• This outline is structured to provide "enough to give one the most essential comprehension of the truth."
• Each heading presents a single high-level point. Any arrowhead symbol can be clicked to open up additional detail. This allows easy movement between the big picture and the details. As Epicurus wrote to Herodotus: "Indeed it is necessary to go back on the main principles, and constantly to fix in one’s memory enough to give one the most essential comprehension of the truth. And in fact the accurate knowledge of details will be fully discovered, if the general principles in the various departments are thoroughly grasped and borne in mind; for even in the case of one fully initiated the most essential feature in all accurate knowledge is the capacity to make a rapid use of observation and mental apprehension, and this can be done if everything is summed up in elementary principles and formulae. For it is not possible for anyone to abbreviate the complete course through the whole system, if he cannot embrace in his own mind by means of short formulae all that might be set out with accuracy in detail."

Epicurean Terminology Frequently Differs From Normal Usage.

...

• Epicurus taught that many commonly-used words should be redefined to be more accurate. Epicurus' use of such key terms as "gods" and "pleasure" does not conform to normal usage, but when used in ancient Epicurean texts they should be understood in the Epicurean way, and this leads to a dramatic difference in interpretation. Among these specialized definitions and perspectives are those in the Definitions and Clarifications section.

Epicurean Philosophy Includes Physics, Canonics, and Ethics.

...

• The importance of the Epicurean views of Physics and Canonics are often overlooked over by modern readers, but they are essential to the proper understanding of the philosophy as a whole, especially the Ethics.

Definitions and Clarifications. The following terms and phrases carry special meaning and significance in Epicurean philosophy:

...

"Gods" exist but are not supernatural, omniscient, omnipotent, or many of the other things people often think about them.

...

• Epicurus held that gods exist, but that they are not supernatural, omniscient, omnipotent, or naturally immortal. While it is clear that Epicurus held that life exists throughout the universe, it is unclear from remaining texts whether Epicurus held that the gods have independent physical existence, or whether they exist only through human conceptual construction of their existence based on cues of their existence that arise naturally in the human mind. Regardless of whether such beings truly exist in the spaces between the worlds, Epicurus clearly held that it is essential to human happiness to have a proper conception of divinity as uninvolved in human affairs but symbolic of blessed living.

"Pleasure" includes but stimulation of the senses and appreciation of sound mind and body.

...

• Epicurus held the term "pleasure" to include all mental and physical agreeable experiences of any kind, including both (1) active stimulations of the senses, and (2) all healthy normal functioning of regular day-to-day life. Epicurus held that there are only two feelings, pleasure and pain, and therefore all experiences of life which are not painful are held to be pleasurable. When Epicureans refer to "Pleasure" as "the guide of life" or "the highest good," they should be understood to be referrring to Pleasure in this two-fold sense.

"Absence of Pain" means the same thing as "pleasure."

...

• Epicurus held that because there are only two feelings, the term "absence of pain" means exactly the same thing as the term "pleasure." Use of the term "absence of pain" should be read to mean nothing more or less than the term "pleasure."

"The Highest Pleasure" means your whole experience is filled with pleasure undiluted by any pain.

...

• The Epicureans combined their observation that Absence of Pain "is" pleasure with the observation that the "height" of pleasure, or the "limit" of pleasure occurs when all pain is is reduced to 0% of experience and all experience is filled with 100% pleaasure. On most occasions, as on the last day his life when Epicurus experienced both the bodily pain of kidney disease and the mental pleasure of his relationships with his friends, some combination of pleasures and pains is to be expected. The Epicureans held that the wise man practicing Epicurean Philosophy will be able to arrange his affairs so that he is generally able to experience more pleasures than pains.

• Epicurus denied that the virtues area absolute or ends in themselves. Considered as tools for the purpose of living pleasurably, however, Epicurus considered the practice of the virtues to be inseparable from a happy life.

"Death Is Nothing To Us" means that after you die you never experience anything ever again.

...

• Epicurus held that human consciousness (the soul or spirit) dissipates and ceases to exist when the body dies. As we no longer exist after death, nothing is of concern to us after death, because we no longer exist to experience anything. This does not mean that the time or manner of death is of no significance to us, because life is desirable, and a painful death is undesirable. After we die, however, we are no longer able to have any concerns at all.

"Nothing Exists Except Atoms And Void" does not mean that the things we see around us are unreal.

...

• Epicurus did not hold that the fact that only atoms and void have permanent unchanging characteristics means that only atoms and void are real. Epicurus considered as "real" anything which affects us, including dreams, and certainly including the properties and qualities of bodies which are made up of combinations of atoms and void. As Professor David Sedley states, "Almost uniquely among Greek philosophers [Epicurus] arrived at what is nowadays the unreflective assumption of almost anyone with a smattering of science, that there are truths at the microscopic level of elementary particles, and further very different truths at the phenomenal level; that the former must be capable of explaining the latter; but that neither level of description has a monopoly of truth. (The truth that sugar is sweet is not straightforwardly reducible to the truth that it has such and such a molecular structure, even though the latter truth may be required in order to explain the former)."

"World" refers not just to the Earth but to our corner of the universe, and there are an innumerable number of other worlds.

...

• Epicurus considered our "World" to consist of the Earth and the bodies we see in the sky including the sun, moon, stars, and planets. Epicurus held that an innumerable number of other such worlds existed, and that the spaces between these worlds (the "intermundia") is suitable for the residence of the Epicurean gods.

"Atoms" refers to the lowest level of indivisible particles

...

• Epicurus considered the "atoms" to be the smallest individual unit of matter, which unit is itself eternal and indivisible. In modern terms Epicurean atoms would likely equate to subatomic particles, but the ultimate meaning of the term to Epicurus was that matter is not infinitely divisible, and that at some level exist particles which cannot be further divided.

"Canon" refers to the measuring stick, not to the thing measured.

...

• The "Canon" was the term used to refer to the method by which Epicurus determined that which is true. The Canon does not constitute a set of propositional truths, but the means of acquiring data about the truth. The three "legs" of the Epicurean Canon are the Five Senses (sight, sound, touch, taste, and smell), the Anticipations (also called Prolepsis, an intuitive faculty by which relationships between data are ascertained), and the "Feelings" (the feelings of pleasure and pain). Epicurus did not consider humans to be born with innate "ideas," but he also did not consider them to be born as a "blank slate."

"All Sensations Are True" means that the senses report without giving their own opinion.

...

• Epicurus taught that the senses, anticipations, and feelings are the tools through which we ultimately judge what is true. Epicurus did not teach that the senses are infallible, or fallible, because the senses do not form opinions of their own, Error exists only in the act of reasoning, and the data reported by the senses are reported "truthfully" because the senses do not inject opinion of their own. All data reported by the senses must be considered to be truthfully reported, but that does not mean that each sensation provides a correct opinion of the full facts. Opinions are judged to be true when confirmed by repeated and consistent sensations over time.

Physics - The Universe Is Composed of Atomic Particles And Void, And Was Not Created By Supernatural Forces.

...

Nature has no gods or supernatural forces of any kind over her.

...

• Lucretius Book Two:
  • [1090] And if you learn this surely, and cling to it, nature is seen, free at once, and quit of her proud rulers, doing all things of her own accord alone, without control of gods. For by the holy hearts of the gods, which in their tranquil peace pass placid years, and a life of calm, who can avail to rule the whole sum of the boundless, who to hold in his guiding hand the mighty reins of the deep, who to turn round all firmaments at once, and warm all fruitful lands with heavenly fires, or to be at all times present in all places, so as to make darkness with clouds, and shake the calm tracts of heaven with thunder, and then shoot thunderbolts, and often make havoc of his own temples, or moving away into deserts rage furiously there, plying the bolt, which often passes by the guilty and does to death the innocent and undeserving?

We deduce that atoms exist because nothing comes from nothing or goes to nothing.

...

Nothing Comes From Nothing:

...

• Epicurus - Letter to Herodotus: [38] ... Having made these points clear, we must now consider things imperceptible to the senses. First of all, that nothing is created out of that which does not exist: for if it were, everything would be created out of everything with no need of seeds.
• Lucretius Book One:
  • [146] This terror then, this darkness of the mind, must needs be scattered not by the rays of the sun and the gleaming shafts of day, but by the outer view and the inner law of nature; whose first rule shall take its start for us from this, that nothing is ever begotten of nothing by divine will. Fear forsooth so constrains all mortal men, because they behold many things come to pass on earth and in the sky, the cause of whose working they can by no means see, and think that a divine power brings them about. Therefore, when we have seen that nothing can be created out of nothing, then more rightly after that shall we discern that for which we search, both whence each thing can be created, and in what way all things come to be without the aid of gods.
  • [159] For if things came to being from nothing, every kind might be born from all things, nought would need a seed. First men might arise from the sea, and from the land the race of scaly creatures, and birds burst forth from the sky; cattle and other herds, and all the tribe of wild beasts, with no fixed law of birth, would haunt tilth and desert. Nor would the same fruits stay constant to the trees, but all would change: all trees might avail to bear all fruits. Why, were there not bodies to bring each thing to birth, how could things have a fixed unchanging mother? But as it is, since all things are produced from fixed seeds, each thing is born and comes forth into the coasts of light, out of that which has in it the substance and first-bodies of each; and ’tis for this cause that all things cannot be begotten of all, because in fixed things there dwells a power set apart.
  • [174] Or again, why do we see the roses in spring, and the corn in summer’s heat, and the vines bursting out when autumn summons them, if it be not that when, in their own time, the fixed seeds of things have flowed together, then is disclosed each thing that comes to birth, while the season is at hand, and the lively earth in safety brings forth the fragile things into the coasts of light? But if they sprang from nothing, suddenly would they arise at uncertain intervals and in hostile times of year, since indeed there would be no first-beginnings which might be kept apart from creative union at an ill-starred season.
  • [184] Nay more, there would be no need for lapse of time for the increase of things upon the meeting of the seed, if they could grow from nothing. For little children would grow suddenly to youths, and at once trees would come forth, leaping from the earth. But of this it is well seen that nothing comes to pass, since all things grow slowly, as is natural, from a fixed seed, and as they grow preserve their kind: so that you can know that each thing grows great, and is fostered out of its own substance.
  • [192] There is this too, that without fixed rain-showers in the year the earth could not put forth its gladdening produce, nor again held apart from food could the nature of living things renew its kind or preserve its life; so that rather you may think that many bodies are common to many things, as we see letters are to words, than that without first-beginnings anything can come to being.
  • [199] Once more, why could not nature produce men so large that on their feet they might wade through the waters of ocean or rend asunder mighty mountains with their hands, or live to overpass many generations of living men, if it be not because fixed substance has been appointed for the begetting of things, from which it is ordained what can arise? Therefore, we must confess that nothing can be brought to being out of nothing, inasmuch as it needs a seed for things, from which each may be produced and brought forth into the gentle breezes of the air.
  • [208] Lastly, inasmuch as we see that tilled grounds are better than the untilled, and when worked by hands yield better produce, we must know that there are in the earth first-beginnings of things, which we call forth to birth by turning the teeming sods with the ploughshare and drilling the soil of the earth. But if there were none such, you would see all things without toil of ours of their own will come to be far better.

Nothing Goes To Nothing:

...

• Epicurus - Letter to Herodotus: [39] And again, if that which disappears were destroyed into that which did not exist, all things would have perished, since that into which they were dissolved would not exist.
• Lucretius Book One:
  [215] Then follows this, that nature breaks up each thing again into its own first-bodies, nor does she destroy ought into nothing. For if anything were mortal in all its parts, each thing would on a sudden be snatched from our eyes, and pass away. For there would be no need of any force, such as might cause disunion in its parts and unloose its fastenings. But as it is, because all things are put together of everlasting seeds, until some force has met them to batter things asunder with its blow, or to make its way inward through the empty voids and break things up, nature suffers not the destruction of anything to be seen.
  [225] Moreover, if time utterly destroys whatsoever through age it takes from sight, and devours all its substance, how is it that Venus brings back the race of living things after their kind into the light of life, or when she has, how does earth, the quaint artificer, nurse and increase them, furnishing food for them after their kind? how is it that its native springs and the rivers from without, coming from afar, keep the sea full? how is it that the sky feeds the stars? For infinite time and the days that are gone by must needs have devoured all things that are of mortal body. But if in all that while, in the ages that are gone by, those things have existed, of which this sum of things consists and is replenished, assuredly they are blessed with an immortal nature; all things cannot then be turned to naught.
  [238] And again, the same force and cause would destroy all things alike, unless an eternal substance held them together, part with part interwoven closely or loosely by its fastenings. For in truth a touch would be cause enough of death, seeing that none of these things would be of everlasting body, whose texture any kind of force would be bound to break asunder. But as it is, because the fastenings of the first-elements are variously put together, and their substance is everlasting, things endure with body unharmed, until there meets them a force proved strong enough to overcome the texture of each. No single thing then passes back to nothing, but all by dissolution pass back into the first-bodies of matter.
  [250] Lastly, the rains pass away, when the sky, our father, has cast them headlong into the lap of earth, our mother; but the bright crops spring up, and the branches grow green upon the trees, the trees too grow and are laden with fruit; by them next our race and the race of beasts is nourished, through them we see glad towns alive with children, and leafy woods on every side ring with the young birds’ cry; through them the cattle wearied with fatness lay their limbs to rest over the glad pastures, and the white milky stream trickles from their swollen udders; through them a new brood with tottering legs sports wanton among the soft grass, their baby hearts thrilling with the pure milk. Not utterly then perish all things that are seen, since nature renews one thing from out another, nor suffers anything to be begotten, unless she be requited by another’s death.

We deduce that the void exists because we see bodies move.

...

• Epicurus Letter To Herodotus - [40] - And if there were not that which we term void and place and intangible existence, bodies would have nowhere to exist and nothing through which to move, as they are seen to move. And besides these two, nothing can even be thought of either by conception or on the analogy of things conceivable such as could be grasped as whole existences and not spoken of as the accidents or properties of such existences. Furthermore, among bodies some are compounds, and others those of which compounds are formed.
• Lucretius Book One (Bailey Edition)
  • [329] And yet all things are not held close pressed on every side by the nature of body; for there is void in things. To have learnt this will be of profit to you in dealing with many things; it will save you from wandering in doubt and always questioning about the sum of things, and distrusting my words. There is then a void, mere space untouchable and empty. For if there were not, by no means could things move; for that which is the office of body, to offend and hinder, would at every moment be present to all things; nothing, therefore, could advance, since nothing could give the example of yielding place. But as it is, through seas and lands and the high tracts of heaven, we descry many things by many means moving in diverse ways before our eyes, which, if there were not void, would not so much be robbed and baulked of restless motion, but rather could in no way have been born at all, since matter would on every side be in close-packed stillness.
  • [346] Again, however solid things may be thought to be, yet from this you can discern that they are of rare body. In rocky caverns the liquid moisture of water trickles through, and all weeps with copious dripping: food spreads itself this way and that into the body of every living thing: trees grow and thrust forth their fruit in due season, because the food is dispersed into every part of them from the lowest roots through the stems and all the branches. Noises creep through walls and fly through the shut places in the house, stiffening cold works its way to the bones: but were there no empty spaces, along which each of these bodies might pass, you would not see this come to pass by any means.
  • [358] Again, why do we see one thing surpass another in weight, when its size is no whit bigger? For if there is as much body in a bale of wool as in lead, it is natural it should weigh as much, since ’tis the office of body to press all things downwards, but on the other hand the nature of void remains without weight. So because it is just as big, yet seems lighter, it tells us, we may be sure, that it has more void; but on the other hand the heavier thing avows that there is more body in it and that it contains far less empty space within. Therefore, we may be sure, that which we are seeking with keen reasoning, does exist mingled in things—that which we call void.

Nothing except atoms and void are by nature eternal and unchanging.

...

• Lucretius Book One -
  • [215] Then follows this, that nature breaks up each thing again into its own first-bodies, nor does she destroy ought into nothing. For if anything were mortal in all its parts, each thing would on a sudden be snatched from our eyes, and pass away. For there would be no need of any force, such as might cause disunion in its parts and unloose its fastenings. But as it is, because all things are put together of everlasting seeds, until some force has met them to batter things asunder with its blow, or to make its way inward through the empty voids and break things up, nature suffers not the destruction of anything to be seen.
• Lucretius Book Five:
  • [235] First of all, since the body of earth and moisture, and the light breath of the winds and burning heat, of which this sum of things is seen to be made up, are all created of a body that has birth and death, of such, too, must we think that the whole nature of the world is fashioned. For verily things whose parts and limbs we see to be of a body that has birth and of mortal shapes, themselves too we perceive always to have death and birth likewise. Wherefore, when we see the mighty members and parts of the world consumed away and brought to birth again, we may know that sky too likewise and earth had some time of first-beginning, and will suffer destruction.

The atoms are constantly in motion, but not so fast that we cannot comprehend the nature of the universe, knowledge, and how to live.

...

• Diogenes of Oinoanda Fragment 5 - Now Aristotle and those who hold the same Peripatetic views as Aristotle say that nothing is scientifically knowable, because things are continually in flux and, on account of the rapidity of the flux, evade our apprehension. We on the other hand acknowledge their flux, but not its being so rapid that the nature of each thing [is] at no time apprehensible by sense-perception. And indeed [in no way would the upholders of] the view under discussion have been able to say (and this is just what they do [maintain] that [at one time] this is [white] and this black, while [at another time] neither this is [white nor] that black, [if] they had not had [previous] knowledge of the nature of both white and black.

Humans have free agency because the swerve of the atom frees us from determinism.

...

• Lucretius Book Two: Lucretius Book Two: [216] Herein I would fain that you should learn this too, that when first-bodies are being carried downwards straight through the void by their own weight, at times quite undetermined and at undetermined spots they push a little from their path: yet only just so much as you could call a change of trend. But if they were not used to swerve, all things would fall downwards through the deep void like drops of rain, nor could collision come to be, nor a blow brought to pass for the first-beginnings: so nature would never have brought aught to being.
• [225] But if perchance any one believes that heavier bodies, because they are carried more quickly straight through the void, can fall from above on the lighter, and so bring about the blows which can give creative motions, he wanders far away from true reason. For all things that fall through the water and thin air, these things must needs quicken their fall in proportion to their weights, just because the body of water and the thin nature of air cannot check each thing equally, but give place more quickly when overcome by heavier bodies. But, on the other hand, the empty void cannot on any side, at any time, support anything, but rather, as its own nature desires, it continues to give place; wherefore all things must needs be borne on through the calm void, moving at equal rate with unequal weights. The heavier will not then ever be able to fall on the lighter from above, nor of themselves bring about the blows, which make diverse the movements, by which nature carries things on. Wherefore, again and again, it must needs be that the first-bodies swerve a little; yet not more than the very least, lest we seem to be imagining a sideways movement, and the truth refute it. For this we see plain and evident, that bodies, as far as in them lies, cannot travel sideways, since they fall headlong from above, as far as you can descry. But that nothing at all swerves from the straight direction of its path, what sense is there which can descry?
• [251] Once again, if every motion is always linked on, and the new always arises from the old in order determined, nor by swerving do the first-beginnings make a certain start of movement to break through the decrees of fate, so that cause may not follow cause from infinite time; whence comes this free will for living things all over the earth, whence, I ask, is it wrested from fate, this will whereby we move forward, where pleasure leads each one of us, and swerve likewise in our motions neither at determined times nor in a determined direction of place, but just where our mind has carried us? For without doubt it is his own will which gives to each one a start for this movement, and from the will the motions pass flooding through the limbs.
• [263] Do you not see too how, when the barriers are flung open, yet for an instant of time the eager might of the horses cannot burst out so suddenly as their mind itself desires? For the whole store of matter throughout the whole body must be roused to movement, that then aroused through every limb it may strain and follow the eager longing of the mind; so that you see a start of movement is brought to pass from the heart, and comes forth first of all from the will of the mind, and then afterwards is spread through all the body and limbs.
• [272] Nor is it the same as when we move forward impelled by a blow from the strong might and strong constraint of another. For then it is clear to see that all the matter of the body moves and is hurried on against our will, until the will has reined it back throughout the limbs. Do you not then now see that, albeit a force outside pushes many men and constrains them often to go forward against their will and to be hurried away headlong, yet there is something in our breast, which can fight against it and withstand it? And at its bidding too the store of matter is constrained now and then to turn throughout the limbs and members, and, when pushed forward, is reined back and comes to rest again.
• [284] Wherefore in the seeds too you must needs allow likewise that there is another cause of motion besides blows and weights, whence comes this power born in us, since we see that nothing can come to pass from nothing. For weight prevents all things coming to pass by blows, as by some force without. But that the very mind feels not some necessity within in doing all things, and is not constrained like a conquered thing to bear and suffer, this is brought about by the tiny swerve of the first-beginnings in no determined direction of place and at no determined time.

The universe is eternal, boundless, and filled with innumerable forms of life.

...

• Lucretius Book Two:
  • [2:1048] First of all, we find that in every direction everywhere, and on either side, above and below, through all the universe, there is no limit, as I have shown, and indeed the truth cries out for itself and the nature of the deep shines clear. Now in no way must we think it likely, since towards every side is infinite empty space, and seeds in unnumbered numbers in the deep universe fly about in many ways driven on in everlasting motion, that this one world and sky was brought to birth, but that beyond it all those bodies of matter do naught; above all, since this world was so made by nature, as the seeds of things themselves of their own accord, jostling from time to time, were driven together in many ways, rashly, idly, and in vain, and at last those united, which, suddenly cast together, might become ever and anon the beginnings of great things, of earth and sea and sky, and the race of living things. Wherefore, again and again, you must needs confess that there are here and there other gatherings of matter, such as is this, which the ether holds in its greedy grip.
  • [2:1067] Moreover, when there is much matter ready to hand, when space is there, and no thing, no cause delays, things must, we may be sure, be carried on and completed. As it is, if there is so great a store of seeds as the whole life of living things could not number, and if the same force and nature abides which could throw together the seeds of things, each into their place in like manner as they are thrown together here, it must needs be that you confess that there are other worlds in other regions, and diverse races of men and tribes of wild beasts.
  • [2:1077] This there is too that in the universe there is nothing single, nothing born unique and growing unique and alone, but it is always of some tribe, and there are many things in the same race. First of all turn your mind to living creatures; you will find that in this wise is begotten the race of wild beasts that haunts the mountains, in this wise the stock of men, in this wise again the dumb herds of scaly fishes, and all the bodies of flying fowls. Wherefore you must confess in the same way that sky and earth and sun, moon, sea, and all else that exists, are not unique, but rather of number numberless; inasmuch as the deep-fixed boundary-stone of life awaits these as surely, and they are just as much of a body that has birth, as every race which is here on earth, abounding in things after its kind.

What we call the soul or spirit is not immortal and cannot survive outside the body.

...

• Lucretius Book Three:
  • [B-3:417] Come now, that you may be able to learn that the minds and the light souls of living things have birth and death, I will hasten to set forth verses long sought out and found with glad effort, worthy to guide your life. Be it yours to link both of these in a single name, and when, to choose a case, I continue to speak of the soul, proving that it is mortal, suppose that I speak of mind as well, inasmuch as they are at one each with the other and compose a single thing.
  • [B-3:425] First of all, since I have shown that it is finely made of tiny bodies and of first-beginnings far smaller than the liquid moisture of water or cloud or smoke—for it far surpasses them in speed of motion, and is more prone to move when smitten by some slender cause; for indeed it is moved by images of smoke and cloud: even as when slumbering in sleep we see altars breathing steam on high, and sending up their smoke; for beyond all doubt these are idols that are borne to us:—now therefore, since, when vessels are shattered, you behold the water flowing away on every side, and the liquid parting this way and that, and since cloud and smoke part asunder into air, you must believe that the soul too is scattered and passes away far more swiftly, and is dissolved more quickly into its first-bodies, when once it is withdrawn from a man’s limbs, and has departed. For indeed, since the body, which was, as it were, the vessel of the soul, cannot hold it together, when by some chance it is shattered and made rare, since the blood is withdrawn from the veins, how could you believe that the soul could be held together by any air, which is more rare than our body and can contain it less?
  • [B-3:445] Moreover, we feel that the understanding is begotten along with the body, and grows together with it, and along with it comes to old age. For as children totter with feeble and tender body, so a weak judgment of mind goes with it. Then when their years are ripe and their strength hardened, greater is their sense and increased their force of mind. Afterward, when now the body is shattered by the stern strength of time, and the frame has sunk with its force dulled, then the reason is maimed, the tongue raves, the mind stumbles, all things give way and fail at once. And so it is natural that all the nature of the mind should also be dissolved, even as is smoke, into the high breezes of the air; inasmuch as we see that it is born with the body, grows with it, and, as I have shown, at the same time becomes weary and worn with age.
  • [B-3:459] Then follows this that we see that, just as the body itself suffers wasting diseases and poignant pain, so the mind too has its biting cares and grief and fear; wherefore it is natural that it should also share in death. Nay more, during the diseases of the body the mind often wanders astray; for it loses its reason and speaks raving words, and sometimes in a heavy lethargy is carried off into a deep unending sleep, when eyes and head fall nodding, in which it hears not voices, nor can know the faces of those who stand round, summoning it back to life, bedewing face and cheeks with their tears. Therefore you must needs admit that the mind too is dissolved, inasmuch as the contagion of disease pierces into it. For both pain and disease are alike fashioners of death, as we have been taught ere now by many a man’s decease.
  • [B-3:476] Again, when the stinging strength of wine has entered into a man, and its heat has spread abroad throughout his veins, why is it that there follows a heaviness in the limbs, his legs are entangled as he staggers, his tongue is sluggish, and his mind heavy, his eyes swim, shouting, sobbing, quarrelling grows apace, and then all the other signs of this sort that go along with them; why does this come to pass, except that the mastering might of the wine is wont to confound the soul even within the body? But whenever things can be so confounded and entangled, they testify that, if a cause a whit stronger shall have made its way within, they must needs perish, robbed of any further life.
  • [B-3:487] Nay more, some man, often before our very eyes, seized suddenly by violent disease, falls, as though by a lightning-stroke, and foams at the mouth; he groans and shivers throughout his frame, he loses his wits, his muscles grow taut, he writhes, he breathes in gasps, and tossing to and fro wearies his limbs. Because, you may be sure, his soul rent asunder by the violence of disease throughout his frame, is confounded, and gathers foam, as on the salt sea the waters boil beneath the stern strength of the winds. Further, the groaning is wrung from him, because his limbs are racked with pain, and more than all because the particles of voice are driven out, and are carried crowding forth from his mouth, along the way they are wont, where is their paved path. Loss of wits comes to pass, because the force of mind and soul is confounded, and, as I have shown, is torn apart and tossed to and fro, rent asunder by that same poison. Thereafter, when by now the cause of malady has ebbed, and the biting humours of the distempered body return to their hiding-places, then, as it were staggering, he first rises, and little by little returns to all his senses, and regains his soul. When mind and soul then even within the body are tossed by such great maladies, and in wretched plight are rent asunder and distressed, why do you believe that without the body in the open air they can continue life amid the warring winds?
  • [B-3:510] And since we perceive that the mind is cured, just like the sick body, and we see that it can be changed by medicine, this too forewarns us that the mind has a mortal life. For whosoever attempts and essays to alter the mind, or seeks to change any other nature, must indeed add parts to it or transfer them from their order, or take away some small whit at least from the whole. But what is immortal does not permit its parts to be transposed, nor that any whit should be added or depart from it. For whenever a thing changes and passes out of its own limits, straightway this is the death of that which was before. And so whether the mind is sick, it gives signs of its mortality, as I have proved, or whether it is changed by medicine. So surely is true fact seen to run counter to false reasoning, and to shut off retreat from him who flees, and with double-edged refutation to prove the falsehood.
  • [B-3:526] Again, we often behold a man pass away little by little and limb by limb lose the sensation of life; first of all the toes and nails on his feet grow livid, then the feet and legs die, thereafter through the rest of his frame, step by step, pass the traces of chill death. Since this nature of the soul is severed nor does it come forth all intact at one moment, it must be counted mortal. But if by chance you think that it could of its own power draw itself inwards through the frame, and contract its parts into one place, and so withdraw sensation from all the limbs, yet nevertheless that place, to which so great abundance of soul is gathered together, must needs be seen possessed of greater sensation; but since such place is nowhere found, you may be sure, as we said before, it is rent in pieces and scattered abroad, and so perishes. Nay more, if it were our wish to grant what is false, and allow that the soul could be massed together in the body of those, who as they die leave the light of day part by part, still you must needs confess that the soul is mortal, nor does it matter whether it passes away scattered through the air, or is drawn into one out of all its various parts and grows sottish, since sense more and more in every part fails the whole man, and in every part less and less of life remains. [B-3:548] And since the mind is one part of man, which abides rooted in a place determined, just as are ears and eyes and all the other organs of sense which guide the helm of life; and, just as hand and eye or nostrils, sundered apart from us, cannot feel nor be, but in fact are in a short time melted in corruption, so the mind cannot exist by itself without the body and the very man, who seems to be, as it were, the vessel of the mind, or aught else you like to picture more closely bound to it, inasmuch as the body clings to it with binding ties.
  • [B-3:558] Again, the living powers of body and mind prevail by union, one with the other, and so enjoy life; for neither without body can the nature of mind by itself alone produce the motions of life, nor yet bereft of soul can body last on and feel sensation. We must know that just as the eye by itself, if torn out by the roots, cannot discern anything apart from the whole body, so, it is clear, soul and mind by themselves have no power. Doubtless because in close mingling throughout veins and flesh, throughout sinews and bones, their first-beginnings are held close by all the body, nor can they freely leap asunder with great spaces between; and so shut in they make those sense-giving motions, which outside the body cast out into the breezes of air after death they cannot make, because they are not in the same way held together. For indeed air will be body, yea a living thing, if the soul can hold itself together, and confine itself to those motions, which before it made in the sinews and right within the body. Wherefore, again and again, when the whole protection of the body is undone and the breath of life is driven without, you must needs admit that the sensations of the mind and the soul are dissolved, since the cause of life in soul and body is closely linked.
  • [B-3:580] Again, since the body cannot endure the severing of the soul, but that it decays with a foul stench, why do you doubt that the force of the soul has gathered together from deep down within, and has trickled out, scattering abroad like smoke, and that the body has changed and fallen crumbling in such great ruin, because its foundations have been utterly moved from their seat, as the soul trickles forth through the limbs, and through all the winding ways, which are in the body, and all the pores? So that in many ways you may learn that the nature of the soul issued through the frame sundered in parts, and that even within the body it was rent in pieces in itself, before it slipped forth and swam out into the breezes of air.
  • [B-3:592] Nay more, while it moves still within the limits of life, yet often from some cause the soul seems to be shaken and to move, and to wish to be released from the whole body; the face seems to grow flaccid, as at the hour of death, and all the limbs to fall limp on the bloodless trunk. Even so it is, when, as men say, the heart has had a shock, or the heart has failed; when all is alarm, and one and all struggle to clutch at the last link to life. For then the mind is shaken through and through, and all the power of the soul, and both fall in ruin with the body too; so that a cause a whit stronger might bring dissolution. Why do you doubt after all this but that the soul, if driven outside the body, frail as it is, without in the open air, robbed of its shelter, would not only be unable to last on through all time, but could not hold together even for a moment?
  • [B-3:607] For it is clear that no one, as he dies, feels his soul going forth whole from all his body, nor coming up first to the throat and the gullet up above, but rather failing in its place in a quarter determined; just as he knows that the other senses are dissolved each in their own place. But if our mind were immortal, it would not at its death so much lament that it was dissolved, but rather that it went forth and left its slough, as does a snake.
  • [B-3:615] Again, why is the understanding and judgment of the mind never begotten in head or feet or hands, but is fixed for all men in one abode in a quarter determined, except that places determined are assigned to each thing for its birth, and in which each several thing can abide when it is created, that so it may have its manifold parts arranged that never can the order of its limbs be seen reversed? So surely does one thing follow on another, nor is flame wont to be born of flowing streams, nor cold to be conceived in fire.
  • [B-3:624] Moreover, if the nature of the soul is immortal and can feel when sundered from our body, we must, I trow, suppose it endowed with five senses. Nor in any other way can we picture to ourselves the souls wandering in the lower world of Acheron. And so painters and the former generations of writers have brought before us souls thus endowed with senses. Yet neither eyes nor nose nor even hand can exist for the soul apart from body, nor again tongue apart or ears; the souls cannot therefore feel by themselves or even exist.
  • [B-3:634] And since we feel that the sensation of life is present in the whole body, and we see that the whole is a living thing, if some force suddenly hew it in the middle with swift blow, so that it severs each half apart, beyond all doubt the force of the soul too will be cleft in twain, torn asunder and riven together with the body. But what is cleft and separates into any parts, disclaims, assuredly, that its nature is everlasting.
  • [B-3:642] They tell how often scythe-bearing chariots, glowing in the mellay of slaughter, so suddenly lop off limbs, that the part which falls lopped off from the frame is seen to shiver on the ground, while in spite of all the mind and spirit of the man cannot feel the pain, through the suddenness of the stroke, and at the same time, because his mind is swallowed up in the fervour of the fight; with the body that is left him he makes for the fight and the slaughter, and often knows not that his left arm with its shield is gone, carried away by the wheels among the horses and the ravening scythes; and another sees not that his right arm has dropped, while he climbs up and presses onward. Then another struggles to rise when his leg is lost, while at his side on the ground his dying foot twitches its toes. And the head lopped off from the warm living trunk keeps on the ground the look of life and the wide-open eyes, until it has yielded up all the last vestiges of soul.
  • [B-3:657] Nay more, if you should choose to chop into many parts with an axe the body of a snake with quivering tongue, angry tail, and long body, you will then perceive all the hewn parts severally writhing under the fresh blow, and scattering the ground with gore, and the fore part making open-mouthed for its own hinder part, in order that, smitten by the burning pain of the wound, it may quench it with its bite. Shall we say then that there is a whole soul in all those little parts? But by that reasoning it will follow that one living creature had many souls in its body. And so that soul which was one together with the body has been severed; wherefore both body and soul must be thought mortal, since each alike is cleft into many parts.
  • [B-3:670] Moreover, if the nature of the soul is immortal, and it enters into the body at our birth, why can we not remember also the part of our life already gone, why do we not preserve traces of things done before? For if the power of the mind is so much changed that all remembrance of things past is lost to it, that state is not, I trow, a far step from death; wherefore you must needs admit that the soul, which was before, has passed away, and that that which now is, has now been created.
  • [B-3:679] Moreover, if when our body is already formed the living power of the mind is wont to be put in just when we are born, and when we are crossing the threshold into life, it would not then be natural that it should be seen to grow with the body, yea, together with the limbs in the very blood, but ’tis natural that it should live all alone by itself as in a den, yet so that the whole body nevertheless is rich in sensation. Wherefore, again and again, we must not think that souls are without a birth, or released from the law of death. For neither can we think that they could be so closely linked to our bodies if they were grafted in them from without—but that all this is so, plain fact on the other hand declares: for the soul is so interlaced through veins, flesh, sinews, and bones that the teeth, too, have their share in sensation; as toothache shows and the twinge of cold water, and the biting on a sharp stone if it be hid in a piece of bread—nor, when they are so interwoven, can they, it is clear, issue forth entire, and unravel themselves intact from all the sinews and bones and joints.
  • [B-3:698] But if by chance you think that the soul is wont to be grafted in us from without, and then permeate through our limbs, all the more will it perish as it fuses with the body. For that which permeates dissolves, and so passes away. For even as food parcelled out among all the pores of the body, when it is sent about into all the limbs and members, perishes and furnishes a new nature out of itself, so soul and mind, however whole they may pass into the fresh-made body, still are dissolved as they permeate, while through all the pores there are sent abroad into the limbs the particles, whereof this nature of the mind is formed, which now holds sway in our body, born from that which then perished, parcelled out among the limbs. Wherefore it is seen that the nature of the soul is neither without a birthday nor exempt from death.
  • [B-3:713] Moreover, are seeds of soul left or not in the lifeless body? For if they are left and are still there, it will follow that it cannot rightly be held immortal, since it has left the body maimed by the loss of some parts. But if it has been removed and fled from the limbs while still entire, so that it has left no part of itself in the body, how is it that corpses, when the flesh is now putrid, teem with worms, and how does so great a store of living creatures, boneless and bloodless, swarm over the heaving frame? But if by chance you believe that the souls are grafted in the worms from without, and can pass severally into their bodies, and do not consider why many thousands of souls should gather together, whence one only has departed, yet there is this that seems worth asking and putting to the test, whether after all those souls go hunting for all the seeds of the little worms, and themselves build up a home to live in, or whether they are, as it were, grafted in bodies already quite formed. But there is no ready reason why they should make the bodies themselves, why they should be at such pains. For indeed, when they are without a body, they do not flit about harassed by disease and cold and hunger. For the body is more prone to suffer by these maladies, and ’tis through contact with the body that the mind suffers many ills. But still grant that it be ever so profitable for them to fashion a body wherein to enter; yet there seems to be no way whereby they could. Souls then do not fashion for themselves bodies and frames. Nor yet can it be that they are grafted in bodies already made; for neither will they be able to be closely interwoven, nor will contact be made by a sharing of sensation.
  • [B-3:741] Again, why does fiery passion go along with the grim brood of lions and cunning with foxes; why is the habit of flight handed on to deer from their sires, so that their father’s fear spurs their limbs? And indeed all other habits of this sort, why are they always implanted in the limbs and temper from the first moment of life, if it be not because a power of mind determined by its own seed and breed grows along with the body of each animal? But if the soul were immortal and were wont to change its bodies, then living creatures would have characters intermingled; the dog of Hyrcanian seed would often flee the onset of the horned hart, and the hawk would fly fearful through the breezes of air at the coming of the dove; men would be witless, and wise the fierce tribes of wild beasts.
  • [B-3:754] For it is argued on false reasoning, when men say that an immortal soul is altered, when it changes its body: for what is changed, is dissolved, and so passes away. For the parts are transferred and shift from their order; wherefore they must be able to be dissolved too throughout the limbs, so that at last they may all pass away together with the body.
  • [B-3:760] But if they say that the souls of men always pass into human bodies, still I will ask why a soul can become foolish after being wise, why no child has reason, why the mare’s foal is not as well trained as the bold strength of a horse. We may be sure they will be driven to say that in a weak body the mind too is weak. But if that indeed comes to pass, you must needs admit that the soul is mortal, since it changes so much throughout the frame, and loses its former life and sense.
  • [B-3:769] Or in what manner will the force of mind be able along with each several body to wax strong and attain the coveted bloom of life, unless it be partner too with the body at its earliest birth? Or why does it desire to issue forth abroad from the aged limbs? does it fear to remain shut up in a decaying body, lest its home, worn out with the long spell of years, fall on it? But an immortal thing knows no dangers.
  • [B-3:776] Again, that the souls should be present at the wedlock of Venus and the birth of wild beasts, seems to be but laughable; that immortal souls should stand waiting for mortal limbs in numbers numberless, and should wrangle one with another in hot haste, which first before the others may find an entrance; unless by chance the souls have a compact sealed, that whichever arrives first on its wings, shall first have entrance, so that they strive not forcibly at all with one another.
  • [B-3:784] Again, a tree cannot exist in the sky, nor clouds in the deep waters, nor can fishes live in the fields, nor blood be present in wood, nor sap in stones. It is determined and ordained where each thing can grow and have its place. So the nature of the mind cannot come to birth alone without body, nor exist far apart from sinews and blood. But if this could be, far sooner might the force of mind itself exist in head or shoulders, or right down in the heels, and be wont to be born in any part you will, but at least remain in the same man or the same vessel. But since even within our body it is determined and seen to be ordained where soul and mind can dwell apart and grow, all the more must we deny that it could continue or be begotten outside the whole body. Wherefore, when the body has perished, you must needs confess that the soul too has passed away, rent asunder in the whole body.
  • [B-3:800] Nay, indeed, to link the mortal with the everlasting, and to think that they can feel together and act one upon the other, is but foolishness. For what can be pictured more at variance, more estranged within itself and inharmonious, than that what is mortal should be linked in union with the immortal and everlasting to brave raging storms?
  • [B-3:806] Moreover, if ever things abide for everlasting, it must needs be either that, because they are of solid body, they beat back assaults, nor suffer anything to come within them which might unloose the close-locked parts within, such as are the bodies of matter whose nature we have declared before; or that they are able to continue throughout all time, because they are exempt from blows, as is the void, which abides untouched, nor suffers a whit from assault; or else because there is no supply of room all around, into which, as it were, things might part asunder and be broken up—even as the sum of sums is eternal—nor is there any room without into which they may scatter, nor are there bodies which might fall upon them and break them up with stout blow.
  • [B-3:819] But if by chance the soul is rather to be held immortal for this reason, because it is fortified and protected from things fatal to life, or because things harmful to its life come not at all, or because such as come in some way depart defeated before we can feel what harm they do us [B-3:clear facts show us that this is not so]. For besides that it falls sick along with the diseases of the body, there comes to it that which often torments it about things that are to be, and makes it ill at ease with fear, and wears it out with care; and when its evil deeds are past and gone, yet sin brings remorse. There is too the peculiar frenzy of the mind and forgetfulness of the past, yes, and it is plunged into the dark waters of lethargy.

There are no Platonic ideal forms or Aristotelian essences.

...

• DeWitt Page 123 - As will be set forth in the chapter on Physics, Epicurus adopted and declared Twelve Elementary Principles, one of which reads: "The universe consists of atoms and void." This is a positive statement. If the implied negative be made explicit, it is this, that there is nothing incorporeal except void. This is destructive of certain teachings of Plato. According to him the sensations inform us only of the things that are transient, that have a beginning and an end. The realities are the eternal forms or ideas, which are not joined up with matter and so are incorporeal. Moreover, according to the same teachings the ideas are apprehensible only by pure reason, which, being, like the ideas, discrete from matter, is itself incorporeal and divine. Logically, therefore, if there is nothing incorporeal except void, the eternal ideas and the divine incorporeal reason are alike absurdities.

Canonics - Knowledge Can Be Obtained Through the Sensations, Anticipations, and Feelings.

...

Knowledge can be obtained, and it is foolish to suggest that nothing can be known.

...

• Lucretius Book IV
  • [469] Again, if any one thinks that nothing is known, he knows not whether that can be known either, since he admits that he knows nothing. Against him then I will refrain from joining issue, who plants himself with his head in the place of his feet. And yet were I to grant that he knows this too, yet I would ask this one question; since he has never before seen any truth in things, whence does he know what is knowing, and not knowing each in turn, what thing has begotten the concept of the true and the false, what thing has proved that the doubtful differs from the certain?
  • [478] You will find that the concept of the true is begotten first from the senses, and that the senses cannot be gainsaid. For something must be found with a greater surety, which can of its own authority refute the false by the true. Next then, what must be held to be of greater surety than sense? Will reason, sprung from false sensation, avail to speak against the senses, when it is wholly sprung from the senses? For unless they are true, all reason too becomes false. Or will the ears be able to pass judgement on the eyes, or touch on the ears? or again will the taste in the mouth refute this touch; will the nostrils disprove it, or the eyes show it false? It is not so, I trow. For each sense has its faculty set apart, each its own power, and so it must needs be that we perceive in one way what is soft or cold or hot, and in another the diverse colours of things, and see all that goes along with colour. Likewise, the taste of the mouth has its power apart; in one way smells arise, in another sounds. And so it must needs be that one sense cannot prove another false. Nor again will they be able to pass judgement on themselves, since equal trust must at all times be placed in them. Therefore, whatever they have perceived on each occasion, is true.
  • [500] And if reason is unable to unravel the cause, why those things which close at hand were square, are seen round from a distance, still it is better through lack of reasoning to be at fault in accounting for the causes of either shape, rather than to let things clear seen slip abroad from your grasp, and to assail the grounds of belief, and to pluck up the whole foundations on which life and existence rest. For not only would all reasoning fall away; life itself too would collapse straightway, unless you chose to trust the senses, and avoid headlong spots and all other things of this kind which must be shunned, and to make for what is opposite to these. Know, then, that all this is but an empty store of words, which has been drawn up and arrayed against the senses.
  • [513] Again, just as in a building, if the first ruler is awry, and if the square is wrong and out of the straight lines, if the level sags a whit in any place, it must needs be that the whole structure will be made faulty and crooked, all awry, bulging, leaning forwards or backwards, and out of harmony, so that some parts seem already to long to fall, or do fall, all betrayed by the first wrong measurements; even so then your reasoning of things must be awry and false, which all springs from false senses.

The senses, feelings, and anticipations are the tests of true knowledge.

...

• Diogenes Laertius 31: "Thus in The Canon Epicurus says that the tests of truth are the sensations and anticipations and the feelings; the Epicureans add to these the intuitive apprehensions of the mind." Direct perceptions of the mind (phantastikai epibolai tes dianoias) are mentioned in the Letter to Herodotus [51] and Principal Doctrine #24, but the remaining texts are unclear as to how direct perceptions of the mind relate to the sensations (aistheseis), anticipations (prolepseis), and feelings (pathe).

The information we obtain about the qualities and properties of bodies that we obtain through our senses is no less real than the atoms.

...

• David Sedley, Epicurus' Refutation of Determinism, p 33: In confirmation of this, we can return to the close and apparently conscious parallelism between Epicurus' treatments of determinism and scepticism. The sceptics refuted in Lucretius IV must be, or prominently include, those fourth-century Detilocriteans like Metrodorus of Chios, Anaxarchus, and even Epicurus' own reviled teacher Nausiphanes, who had played up the sceptical side of Democritus' thought, and against whom Epicurus was eager to marshal the positive empiricist arguments which Democritus had also bequeathed.39 This scepticism was the result of what I shall call reductionist atomism. Because phenomenal objects and properties seemed to reduce to mere configurations of atoms and void, Democritus was inclined to suppose that the atoms and void were real while the phenomenal objects and properties were no more than arbitrary constructions placed upon them by human cognitive organs. In his more extreme moods Democritus was even inclined to doubt the power of human judgment, since judgment was itself no more than a realignment of atoms in the mind XXX. Epicurus' response to this is perhaps the least appreciated aspect of his thought. It was to reject reductionist atomism. Almost uniquely among Greek philosophers he arrived at what is nowadays the unreflective assumption of almost anyone with a smattering of science, that there are truths at the microscopic level of elementary particles, and further very different truths at the phenomenal level; that the former must be capable of explaining the latter; but that neither level of description has a monopoly of truth. (The truth that sugar is sweet is not straightforwardly reducible to the truth that it has such and such a molecular structure, even though the latter truth may be required in order to explain the former). By establishing that cognitive scepticism, the direct outcome of reductionist atomism, is self-refuting and untenable in practice, Epicurus justifies his non-reductionist alternative, according to which sensations are true and there are therefore bona fide truths at the phenomenal level accessible through them. The same will apply to the XXX, which Epicurus also held to be veridical. Pleasure, for example, is a direct datum of experience. It is commonly assumed that Epicurus must have equated pleasure with such and such a kind of movement of soul atoms; but although he will have taken it to have some explanation at the atomic level, I know of no evidence that he, any more than most moral philosophers or psychologists, would have held that an adequate analysis of it could be found at that level. Physics are strikingly absent from Epicurus' ethical writings, and it is curious that interpreters are so much readier to import them there than they are when it comes to the moral philosophy of Plato or Aristotle.

The information we obtain through the feelings of pleasure and pain and the anticipations is also "real."

...

• Diogenes Laertius Biography of Epicurus [32] Nor is there anything which can refute the sensations. For a similar sensation cannot refute a similar because it is equivalent in validity, nor a dissimilar a dissimilar, for the objects of which they are the criteria are not the same; nor again can reason, for all reason is dependent upon sensations; nor can one sensation refute another, for we attend to them all alike. Again, the fact of apperception confirms the truth of the sensations. And seeing and hearing are as much facts as feeling pain. From this it follows that as regards the imperceptible we must draw inferences from phenomena. For all thoughts have their origin in sensations by means of coincidence and analogy and similarity and combination, reasoning too contributing something. And the visions of the insane and those in dreams are true, for they cause movement, and that which does not exist cannot cause movement.
• Epicurus Letter to Herodotus - [62] Moreover, it will be said that in compound bodies too one atom is faster than another, though as a matter of fact all are equal in speed: this will be said because even in the least period of continuous time all the atoms in aggregate bodies move towards one place, even though in moments of time perceptible only by thought they do not move towards one place but are constantly jostling one against another, until the continuity of their movement comes under the ken of sensation. For the addition of opinion with regard to the unseen, that the moments perceptible only by thought will also contain continuity of motion, is not true in such cases; for we must remember that it is what we observe with the senses or grasp with the mind by an apprehension that is true.

All sensations are "true" to us.

...

• DeWitt 142 - By way of concluding this account of the Sensations as criteria it is well to present a synoptic view of the evidence. Nowhere in our extant Little Epitome or the Authorized Doctrines do we find the statement "that all sensations are true." On the contrary, the Epitome begins by urging the student "to give heed to the sensations under all circumstances and especially the immediate perceptions whether of the intelligence or of any criterion whatsoever," which manifestly allows some value to all sensations and special value to immediate sensations. At the end of the Epitome the student is warned to check his own observations by those of others. These authentic statements are incompatible with belief in the infallibility of sensation. They presume belief in gradations of value among sensations and also the need of perpetual caution against error.
• DeWitt 138 - While Epicurus was adamant in his determination to defend the validity of the sensations as being the means of direct contact between man and reality and as possessing precedence over reason, he exhibits no desire to defend the individual sensation. The fallacies of those who impute to him belief in the infallibility of sensation lie partly in their failure to observe the ambiguity of the word true and in their confusion of "truth" with "value." It is not difficult to differentiate the various meanings of true and it is essential to right understanding. For example, when Epicurus declared that "the phantasms seen by the insane and in dreams are true," he meant that they were "real" and existed independently of the madman or the dreamer, because "they act as a stimulus and that which does not exist does not deliver a stimulus." These phantasms, however, are not "true" in the sense that a sensation experienced by the waking observer is true. The dreamer may have a vision of a centaur but no centaurs exist in real life. If the waking man sees an ox, then the sensation is true because the stimulus is delivered by a living ox. A still different meaning of true may be discerned when Epicurus denominates his system as "true philosophy." He means it is true in the sense that his Twelve Elementary Principles are true or in the sense that the modern scientist believes the accepted calculation of the speed of light to be true. This may be called absolute truth, if there is such a thing. It remains to speak of the relatively true. The views of a tower at various distances may be cited as examples. Each is true relative to the distance; its value as evidence of the facts is another mauer. This distinction was no novelty to the ancients; Sextus Empiricus sets it forth at some length in a discussion of Epicureanism.
• DeWitt 139 - Also worthy of mention is the sensation which is optically true but false to the facts. An example much brandished by the skeptics was the bent image of the oar immersed in the water. Epicurus made logical provision for this difficulty: "Of two sensations the one cannot refute the other, because we give attention to all sensations." This statement alone would acquit him of belief in the infallibility of sensation, because it is distinctly implied that some sensations are employed to correct others. The example of the tower will serve as a transition from the topic of ambiguity to that of confusion. When modern scholars seize upon the saying "all sensations are true," which appears nowhere in the extant writings of Epicurus, and stretch it to mean that all sensations are reliable or trustworthy or "that the senses cannot be deceived," they are confusing the concept of truth with the concept of value. They overlook the fact that even a truthful witness may fall short of delivering the whole truth or may even give false evidence. The distant view of the square tower is quite true relative to the distance but it fails to reveal the whole truth about the tower.
• DeWitt 139 - To assume that Epicurus was unaware of these plain truths, as one must if belief in the infallibility of sensation is imputed to him, is absurd. It is because he was aware that the value of sensations, apart from their truth, varied all the way from totality to zero, that he exhorted beginners "under all circumstances to watch the sensations and especially the immediate perceptions whether of the intellect or any of the criteria whatsoever." Obviously, so far from thinking the sensations infallible, he was keenly aware of the possibility of error and drew sharp attention to the superior values of immediate sensations. When once these ambiguities and confusions have been discerned and eliminated, it is possible to state the teaching of Epicurus with some of that precision by which he set high store. In the meaning of the Canon, then, a sensation is an aisthesis. All such sensations may possess value; otherwise there would be no sense in saying, "We pay attention to all sensations." Their values, however, range all the way from totality to zero. The value is total only when the sensation is immediate.

Nature has priority over reason.

...

• DeWitt 128 - This ascription of benevolence to Nature and the narrowing of the concept to denote human nature or the composite experience of the race all reflects the pronounced ethical bias of Epicurus. Along with this bias goes a deliberate plan to exalt Nature over reason. In point of time and succession Nature is made to possess precedence. His most telling argument has been preserved by Cicero. Let it be assumed that a human being has been deprived of all his five senses. This is tantamount to death and the subject has ceased to be a rational creature. In a muddled paragraph our biographer Laertius ascribes to Epicums the idea "that the Sensations lead the way." In the present context this notion seems to have apposite application: the possession of sensation seems to be construed as antecedent to rational activity. The priority of Nature was also insisted upon in establishing the identity of the end or telos. Aristotle had furnished a precious hint in this connection; he wrote "that perhaps even in the case of the lower animals there is some natural good superior to their scale of intelligence which aims at the corresponding good." To this principle Epicurus adapted his procedure. By the promptings of Nature alone, apart from reason, every animate thing, the moment it is born, reaches out for pleasure and shrinks from pain. Consistent with this reasoning is the steady practice of referring to pleasure as "the end of Nature," which occurs five times in our scant remains. As analogous phrases may be cited "the good of Nature" and "the pleasure of Nature," all of them imply- ing that reason played no necessary role in establishing the truth. Similar is the implication of parallel phrases such as lithe wealth of Nature," signifying that Nature and not reason reveals the true meaning of wealth; and also "the limits of Nature," implying that Nature and not reason teaches the true limits of the desires.

Practical reason is the way the wise person makes decisions.

• DeWitt 125 - Three kinds of reason are thus recognized: first, a dependable kind that proceeds by deduction from first principles; second, an inferior kind that proceeds by analogy from the visible to the invisible and is subject to correction by the former; third, ordinary human intelligence (dianoia), which is normally automatic and hence fallible and is subject to correction by the volitional intelligence. Common to all these forms of reason is their restriction to the human mind; all are faculties of that mind. Outside of this human mind there is no reason in the universe, no world-mind which expresses itself in eternal ideas, regularities of motion, harmonic relationships, and spherical perfections and is identifiable with truth itself.

Ethics - The Feeling of Pleasure Is The Guide of Life.

...

Ethics cannot be based on supernatural gods because supernatural gods do not exist.

...

• Lucretius Book Two: [1090] And if you learn this surely, and cling to it, nature is seen, free at once, and quit of her proud rulers, doing all things of her own accord alone, without control of gods. For by the holy hearts of the gods, which in their tranquil peace pass placid years, and a life of calm, who can avail to rule the whole sum of the boundless, who to hold in his guiding hand the mighty reins of the deep, who to turn round all firmaments at once, and warm all fruitful lands with heavenly fires, or to be at all times present in all places, so as to make darkness with clouds, and shake the calm tracts of heaven with thunder, and then shoot thunderbolts, and often make havoc of his own temples, or moving away into deserts rage furiously there, plying the bolt, which often passes by the guilty and does to death the innocent and undeserving?

Ethics cannot be based on a logic deriving from Platonic ideal forms or Aristotelian essences such things do not exist.

...

• DeWitt Page 123 - As will be set forth in the chapter on Physics, Epicurus adopted and declared Twelve Elementary Principles, one of which reads: "The universe consists of atoms and void." This is a positive statement. If the implied negative be made explicit, it is this, that there is nothing incorporeal except void. This is destructive of certain teachings of Plato. According to him the sensations inform us only of the things that are transient, that have a beginning and an end. The realities are the eternal forms or ideas, which are not joined up with matter and so are incorporeal. Moreover, according to the same teachings the ideas are apprehensible only by pure reason, which, being, like the ideas, discrete from matter, is itself incorporeal and divine. Logically, therefore, if there is nothing incorporeal except void, the eternal ideas and the divine incorporeal reason are alike absurdities.

There is no life after death and therefore no heaven or hell or reward or punishment after death.

...

• Epicurus To Herodotus
  • [64] Further, you must grasp that the soul possesses the chief cause of sensation: yet it could not have acquired sensation, unless it were in some way enclosed by the rest of the structure. And this in its turn having afforded the soul this cause of sensation acquires itself too a share in this contingent capacity from the soul. Yet it does not acquire all the capacities which the soul possesses: and therefore when the soul is released from the body, the body no longer has sensation. For it never possessed this power in itself, but used to afford opportunity for it to another existence, brought into being at the same time with itself: and this existence, owing to the power now consummated within itself as a result of motion, used spontaneously to produce for itself the capacity of sensation and then to communicate it to the body as well, in virtue of its contact and correspondence of movement, as I have already said.
  • [65] Therefore, so long as the soul remains in the body, even though some other part of the body be lost, it will never lose sensation; nay more, whatever portions of the soul may perish too, when that which enclosed it is removed either in whole or in part, if the soul continues to exist at all, it will retain sensation. On the other hand the rest of the structure, though it continues to exist either as a whole or in part, does not retain sensation, if it has once lost that sum of atoms, however small it be, which together goes to produce the nature of the soul. Moreover, if the whole structure is dissolved, the soul is dispersed and no longer has the same powers nor performs its movements, so that it does not possess sensation either.
  • [66] For it is impossible to imagine it with sensation, if it is not in this organism and cannot effect these movements, when what encloses and surrounds it is no longer the same as the surroundings in which it now exists and performs these movements.
  • [67] Furthermore, we must clearly comprehend as well, that the incorporeal in the general acceptation of the term is applied to that which could be thought of as such as an independent existence. Now it is impossible to conceive the incorporeal as a separate existence, except the void: and the void can neither act nor be acted upon, but only provides opportunity of motion through itself to bodies. So that those who say that the soul is incorporeal are talking idly. For it would not be able to act or be acted on in any respect, if it were of this nature. But as it is, both these occurrences are clearly distinguished in respect of the soul.
• Epicurus to Menoeceus 124 - Become accustomed to the belief that death is nothing to us. For all good and evil consists in sensation, but death is deprivation of sensation. And therefore a right understanding that death is nothing to us makes the mortality of life enjoyable, not because it adds to it an infinite span of time, but because it takes away the craving for immortality.
• Lucretius Book 3 -
  • [3:417] Come now, that you may be able to learn that the minds and the light souls of living things have birth and death, I will hasten to set forth verses long sought out and found with glad effort, worthy to guide your life. Be it yours to link both of these in a single name, and when, to choose a case, I continue to speak of the soul, proving that it is mortal, suppose that I speak of mind as well, inasmuch as they are at one each with the other and compose a single thing.
  • [3:425] First of all, since I have shown that it is finely made of tiny bodies and of first-beginnings far smaller than the liquid moisture of water or cloud or smoke—for it far surpasses them in speed of motion, and is more prone to move when smitten by some slender cause; for indeed it is moved by images of smoke and cloud: even as when slumbering in sleep we see altars breathing steam on high, and sending up their smoke; for beyond all doubt these are idols that are borne to us:—now therefore, since, when vessels are shattered, you behold the water flowing away on every side, and the liquid parting this way and that, and since cloud and smoke part asunder into air, you must believe that the soul too is scattered and passes away far more swiftly, and is dissolved more quickly into its first-bodies, when once it is withdrawn from a man’s limbs, and has departed. For indeed, since the body, which was, as it were, the vessel of the soul, cannot hold it together, when by some chance it is shattered and made rare, since the blood is withdrawn from the veins, how could you believe that the soul could be held together by any air, which is more rare than our body and can contain it less?
  • [B-3:445] Moreover, we feel that the understanding is begotten along with the body, and grows together with it, and along with it comes to old age. For as children totter with feeble and tender body, so a weak judgment of mind goes with it. Then when their years are ripe and their strength hardened, greater is their sense and increased their force of mind. Afterward, when now the body is shattered by the stern strength of time, and the frame has sunk with its force dulled, then the reason is maimed, the tongue raves, the mind stumbles, all things give way and fail at once. And so it is natural that all the nature of the mind should also be dissolved, even as is smoke, into the high breezes of the air; inasmuch as we see that it is born with the body, grows with it, and, as I have shown, at the same time becomes weary and worn with age.
  • [B-3:459] Then follows this that we see that, just as the body itself suffers wasting diseases and poignant pain, so the mind too has its biting cares and grief and fear; wherefore it is natural that it should also share in death. Nay more, during the diseases of the body the mind often wanders astray; for it loses its reason and speaks raving words, and sometimes in a heavy lethargy is carried off into a deep unending sleep, when eyes and head fall nodding, in which it hears not voices, nor can know the faces of those who stand round, summoning it back to life, bedewing face and cheeks with their tears. Therefore you must needs admit that the mind too is dissolved, inasmuch as the contagion of disease pierces into it. For both pain and disease are alike fashioners of death, as we have been taught ere now by many a man’s decease.

Nature gives nothing else besides two categories of feeling - Pleasure and Pain - by which to determine what to choose and what to avoid.

...

• Torquatus In On Ends Book One: Every creature, as soon as it is born, seeks after pleasure and delights therein as in its supreme good, while it recoils from pain as its supreme evil, and banishes that, so far as it can, from its own presence, and this it does while still uncorrupted, and while nature herself prompts unbiased and unaffected decisions. So he says we need no reasoning or debate to shew why pleasure is matter for desire, pain for aversion. These facts he thinks are simply perceived, just as the fact that fire is hot, snow is white, and honey sweet, no one of which facts are we bound to support by elaborate arguments; it is enough merely to draw attention to the fact; and there is a difference between proof and formal argument on the one hand and a slight hint and direction of the attention on the other; the one process reveals to us mysteries and things under a veil, so to speak; the other enables us to pronounce upon patent and evident facts. Moreover, seeing that if you deprive a man of his senses there is nothing left to him, it is inevitable that nature herself should be the arbiter of what is in accord with or opposed to nature. Now what facts does she grasp or with what facts is her decision to seek or avoid any particular thing concerned, unless the facts of pleasure and pain?

Because there are only two feelings, "pleasure" is the same as "absence of pain," and includes all bodily and mental experiences which are not painful. There is no pain where pleasure is present, and thus pleasure is present where pain is absent.

...

• Epicurus [PD03]: The limit of quantity in pleasures is the removal of all that is painful. Wherever pleasure is present, as long as it is there, there is neither pain of body, nor of mind, nor of both at once.
• Epicurus Letter to Menoeceus: By pleasure we mean the absence of pain in the body and of trouble in the soul.
• Diogenes Laertius X-34: The internal sensations they say are two, pleasure and pain, which occur to every living creature, and the one is akin to nature and the other alien: by means of these two choice and avoidance are determined.
• On Ends Book One, 30: Moreover, seeing that if you deprive a man of his senses there is nothing left to him, it is inevitable that nature herself should be the arbiter of what is in accord with or opposed to nature. Now what facts does she grasp or with what facts is her decision to seek or avoid any particular thing concerned, unless the facts of pleasure and pain?
• On Ends Book One, 38: Therefore Epicurus refused to allow that there is any middle term between pain and pleasure; what was thought by some to be a middle term, the absence of all pain, was not only itself pleasure, but the highest pleasure possible. Surely any one who is conscious of his own condition must needs be either in a state of pleasure or in a state of pain. Epicurus thinks that the highest degree of pleasure is defined by the removal of all pain, so that pleasure may afterwards exhibit diversities and differences but is incapable of increase or extension.
• On Ends Book One, 39: For if that were the only pleasure which tickled the senses, as it were, if I may say so, and which overflowed and penetrated them with a certain agreeable feeling, then even a hand could not be content with freedom from pain without some pleasing motion of pleasure. But if the highest pleasure is, as Epicurus asserts, to be free from pain, then, O Chrysippus, the first admission was correctly made to you, that the hand, when it was in that condition, was in want of nothing; but the second admission was not equally correct, that if pleasure were a good it would wish for it. For it would not wish for it for this reason, inasmuch as whatever is free from pain is in pleasure.
• On Ends Book One, 56: By this time so much at least is plain, that the intensest pleasure or the intensest annoyance felt in the mind exerts more influence on the happiness or wretchedness of life than either feeling, when present for an equal space of time in the body. We refuse to believe, however, that when pleasure is removed, grief instantly ensues, excepting when perchance pain has taken the place of the pleasure; but we Embrace of Practical Reasonthink on the contrary that we experience joy on the passing away of pains, even though none of that kind of pleasure which stirs the senses has taken their place; and from this it may be understood how great a pleasure it is to be without pain. [57] But as we are elated by the blessings to which we look forward, so we delight in those which we call to memory. Fools however are tormented by the recollection of misfortunes; wise men rejoice in keeping fresh the thankful recollection of their past blessings. Now it is in the power of our wills to bury our adversity in almost unbroken forgetfulness, and to agreeably and sweetly remind ourselves of our prosperity. But when we look with penetration and concentration of thought upon things that are past, then, if those things are bad, grief usually ensues, if good, joy.
• On Ends Book One, 62: But these doctrines may be stated in a certain manner so as not merely to disarm our criticism, but actually to secure our sanction. For this is the way in which Epicurus represents the wise man as continually happy; he keeps his passions within bounds; about death he is indifferent; he holds true views concerning the eternal gods apart from all dread; he has no hesitation in crossing the boundary of life, if that be the better course. Furnished with these advantages he is continually in a state of pleasure, and there is in truth no moment at which he does not experience more pleasures than pains. For he remembers the past with thankfulness, and the present is so much his own that he is aware of its importance and its agreeableness, nor is he in dependence on the future, but awaits it while enjoying the present; he is also very far removed from those defects of character which I quoted a little time ago, and when he compares the fool’s life with his own, he feels great pleasure. And pains, if any befall him, have never power enough to prevent the wise man from finding more reasons for joy than for vexation.
• On Ends Book Two, 9 : Cicero: …[B]ut unless you are extraordinarily obstinate you are bound to admit that 'freedom from pain' does not mean the same thing as 'pleasure.' Torquatus: “Well but on this point you will find me obstinate, for it is as true as any proposition can be.
• On Ends, Book Two, 11: Cicero: Still, I replied, granting that there is nothing better (that point I waive for he moment), surely it does not therefore follow that what I may call the negation of pain is the same thing as pleasure? Torquatus: Absolutely the same, indeed the negation of pain is a very intense pleasure, he most intense pleasure possible.
• On Ends Book Two, 16 : This, O Torquatus, is doing violence to one's senses; it is wresting out of our minds the understanding of words with which we are imbued; for who can avoid seeing that these three states exist in the nature of things: first, the state of being in pleasure; secondly, that of being in pain; thirdly, that of being in such a condition as we are at this moment, and you too, I imagine, that is to say, neither in pleasure nor in pain; in such pleasure, I mean, as a man who is at a banquet, or in such pain as a man who is being tortured. What! do you not see a vast multitude of men who are neither rejoicing nor suffering, but in an intermediate state between these two conditions? No, indeed, said he; I say that all men who are free from pain are in pleasure, and in the greatest pleasure too. Do you, then, say that the man who, not being thirsty himself, mingles some wine for another, and the thirsty man who drinks it when mixed, are both enjoying the same pleasure?
• Epicurus to Idomeneus, Diogenes Laertius: On this blissful day, which is also the last of my life, I write this to you. My continual sufferings from strangury and dysentery are so great that nothing could increase them; but I set above them all the gladness of mind at the memory of our past conversations. But I would have you, as becomes your lifelong attitude to me and to philosophy, watch over the children of Metrodorus.
• Lucretius Book 3 line 98: Thus often the body, which is clear to see, is sick, when, all the same we feel pleasure in some other hidden part; and contrariwise it happens that the reverse often comes to be in turn, when one wretched in mind feels pleasure in all his body; in no other wise than if, when a sick man’s foot is painful, all the while, may be, his head is in no pain. Moreover, when the limbs are given up to soft sleep, and the heavy body lies slack and senseless, yet there is something else in us, which at that very time is stirred in many ways, and admits within itself all the motions of joy and baseless cares of heart.

The limit of quantity of pleasure that a person can experience is reached when that person feels only pleasures and no pains of body or mind.

...

• Epicurus PD03. The limit of quantity in pleasures is the removal of all that is painful. Wherever pleasure is present, as long as it is there, there is neither pain of body, nor of mind, nor of both at once.

Pleasure is the only thing which is desirable in and of itself, and is the alpha and omega and guide of life.

...

• Epicurus to Menoeceus - [129] And for this cause we call pleasure the beginning and end of the blessed life. For we recognize pleasure as the first good innate in us, and from pleasure we begin every act of choice and avoidance, and to pleasure we return again, using the feeling as the standard by which we judge every good. And since pleasure is the first good and natural to us, for this very reason we do not choose every pleasure, but sometimes we pass over many pleasures, when greater discomfort accrues to us as the result of them: and similarly we think many pains better than pleasures, since a greater pleasure comes to us when we have endured pains for a long time. Every pleasure then because of its natural kinship to us is good, yet not every pleasure is to be chosen: even as every pain also is an evil, yet not all are always of a nature to be avoided.
• Lucretius 2:167 - But some in opposition to this, ignorant of matter, believe that nature cannot without the providence of the gods, in such nice conformity to the ways of men, vary the seasons of the year and bring forth crops, ay and all the other things, which divine pleasure, the guide of life, prompts men to approach, escorting them in person and enticing them by her fondlings to continue their races through the arts of Venus, that mankind may not come to an end.

Mental pleasures and pains can be more significant to us than bodily pleasures and pains.

...

• Torquatus in Cicero's On Ends, Book One XVII - Again, we aver that mental pleasures and pains arise out of bodily ones (and therefore I allow your contention that any Epicureans who think otherwise put themselves out of court; and I am aware that many do, though not those who can speak with authority); but although men do experience mental pleasure that is agreeable and mental pain that is annoying, yet both of these we assert arise out of and are based upon bodily sensations. (3) Yet we maintain that this does not preclude mental pleasures and pains from being much more intense than those of the body; since the body can feel only what is present to it at the moment, whereas the mind is also cognizant of the past and of the future. For granting that pain of body is equally painful, yet our sensation of pain can be enormously increased by the belief that some evil of unlimited magnitude and duration threatens to befall us hereafter. And the same consideration may be transferred to pleasure: a pleasure is greater if not accompanied by any apprehension of evil. This therefore clearly appears, that intense mental pleasure or distress contributes more to our happiness or misery than a bodily pleasure or pain of equal duration.

Pain is undesirable, but pain should be chosen when greater pleasure or lesser pain results.

...

• Epicurus to Menoeceus: [129] And for this cause we call pleasure the beginning and end of the blessed life. For we recognize pleasure as the first good innate in us, and from pleasure we begin every act of choice and avoidance, and to pleasure we return again, using the feeling as the standard by which we judge every good. And since pleasure is the first good and natural to us, for this very reason we do not choose every pleasure, but sometimes we pass over many pleasures, when greater discomfort accrues to us as the result of them: and similarly we think many pains better than pleasures, since a greater pleasure comes to us when we have endured pains for a long time. Every pleasure then because of its natural kinship to us is good, yet not every pleasure is to be chosen: even as every pain also is an evil, yet not all are always of a nature to be avoided.
• Torquatus In Cicero's On Ends, Book One, X - But I must explain to you how all this mistaken idea of reprobating pleasure and extolling pain arose. To do so, I will give you a complete account of the system, and expound the actual teachings of the great explorer of the truth, the master-builder of human happiness. No one rejects, dislikes or avoids pleasure itself, because it is pleasure, but because those who do not know how to pursue pleasure rationally encounter consequences that are extremely painful. Nor again is there anyone who loves or pursues or desires to obtain pain of itself, because it is pain, but because occasionally circumstances occur in which toil and pain can procure him some great pleasure. To take a trivial example, which of us ever undertakes laborious physical exercise, except to obtain some advantage from it? But who has any right to find fault with a man who chooses to enjoy a pleasure that has no annoying consequences, or one who avoids a pain that produces no resultant pleasure? On the other hand, we denounce with righteous indignation and dislike men who are so beguiled and demoralized by the charms of the pleasure of the moment, so blinded by desire, that they cannot foresee the pain and trouble that are bound to ensue; and equal blame belongs to those who fail in their duty through weakness of will, which is the same as saying through shrinking from toil and pain. These cases are perfectly simple and easy to distinguish. In a free hour, when our power of choice is untrammeled and when nothing prevents our being able to do what we like best, every pleasure is to be welcomed and every pain avoided. But in certain emergencies and owing to the claims of duty or the obligations of business it will frequently occur that pleasures have to be repudiated and annoyances accepted. The wise man therefore always holds in these matters to this principle of selection: he rejects pleasures to secure other greater pleasures, or else he endures pains to avoid worse pains.

Pain is manageable because it is short if intense, endurable if long, and terminable by death if it is not endurable.

...

• PD04. Pain does not last continuously in the flesh, but the acutest pain is there for a very short time, and even that which just exceeds the pleasure in the flesh does not continue for many days at once. But chronic illnesses permit a predominance of pleasure over pain in the flesh.
• Torquatus in On Ends Book One - XII. The truth of the position that pleasure is the ultimate good will most readily appear from the following illustration. Let us imagine a man living in the continuous enjoyment of numerous and vivid pleasures alike of body and of mind, undisturbed either by the presence or by the prospect of pain: what possible state of existence could we describe as being more excellent or more desirable? One so situated must possess in the first place a strength of mind that is proof against all fear of death or of pain; he will know that death means complete unconsciousness, and that pain is generally light if long and short if strong, so that its intensity is compensated by brief duration and its continuance by diminishing severity.
• Torquatus In On Ends Book One - XV - So on the other hand a strong and lofty spirit is entirely free from anxiety and sorrow. It makes light of death, for the dead are only as they were before they were born. It is schooled to encounter pain by recollecting that pains of great severity are ended by death, and slight ones have frequent intervals of respite; while those of medium intensity lie within our own control: we can bear them if they are endurable, or if they are not, we may serenely quit life's theater, when the play has ceased to please us. These considerations prove that timidity and cowardice are not blamed, nor courage and endurance praised, on their own account; the former are rejected because they beget pain, the latter coveted because they beget pleasure.

Humans have a degree of free will and are therefore responsible for their actions, which are not dictated by Fate.

...

• Epicurus Letter to Menoeceus - [133] For indeed who, think you, is a better man than he who holds reverent opinions concerning the gods, and is at all times free from fear of death, and has reasoned out the end ordained by nature? He understands that the limit of good things is easy to fulfill and easy to attain, whereas the course of ills is either short in time or slight in pain; he laughs at (destiny), whom some have introduced as the mistress of all things. (He thinks that with us lies the chief power in determining events, some of which happen by necessity) and some by chance, and some are within our control; for while necessity cannot be called to account, he sees that chance is inconstant, but that which is in our control is subject to no master, and to it are naturally attached praise and blame. For, indeed, it were better to follow the myths about the gods than to become a slave to the destiny of the natural philosophers: for the former suggests a hope of placating the gods by worship, whereas the latter involves a necessity which knows no placation. As to chance, he does not regard it as a god as most men do (for in a god’s acts there is no disorder), nor as an uncertain cause (of all things) for he does not believe that good and evil are given by chance to man for the framing of a blessed life, but that opportunities for great good and great evil are afforded by it. He believes that the misfortune of the wise is better than the prosperity of the fool. It is better, in short, that what is well judged in action should not owe its successful issue to the aid of chance.
• Lucretius Book Two - [251] Once again, if every motion is always linked on, and the new always arises from the old in order determined, nor by swerving do the first-beginnings make a certain start of movement to break through the decrees of fate, so that cause may not follow cause from infinite time; whence comes this free will for living things all over the earth, whence, I ask, is it wrested from fate, this will whereby we move forward, where pleasure leads each one of us, and swerve likewise in our motions neither at determined times nor in a determined direction of place, but just where our mind has carried us? For without doubt it is his own will which gives to each one a start for this movement, and from the will the motions pass flooding through the limbs. [263] Do you not see too how, when the barriers are flung open, yet for an instant of time the eager might of the horses cannot burst out so suddenly as their mind itself desires? For the whole store of matter throughout the whole body must be roused to movement, that then aroused through every limb it may strain and follow the eager longing of the mind; so that you see a start of movement is brought to pass from the heart, and comes forth first of all from the will of the mind, and then afterwards is spread through all the body and limbs. [272] Nor is it the same as when we move forward impelled by a blow from the strong might and strong constraint of another. For then it is clear to see that all the matter of the body moves and is hurried on against our will, until the will has reined it back throughout the limbs. Do you not then now see that, albeit a force outside pushes many men and constrains them often to go forward against their will and to be hurried away headlong, yet there is something in our breast, which can fight against it and withstand it? And at its bidding too the store of matter is constrained now and then to turn throughout the limbs and members, and, when pushed forward, is reined back and comes to rest again. [284] Wherefore in the seeds too you must needs allow likewise that there is another cause of motion besides blows and weights, whence comes this power born in us, since we see that nothing can come to pass from nothing. For weight prevents all things coming to pass by blows, as by some force without. But that the very mind feels not some necessity within in doing all things, and is not constrained like a conquered thing to bear and suffer, this is brought about by the tiny swerve of the first-beginnings in no determined direction of place and at no determined time.

Happiness requires a proper view that the gods are not supernatural but rather models of blessed living, and they do not interfere in the affairs of men.

...

• PD12. A man cannot dispel his fear about the most important matters if he does not know what is the nature of the universe, but suspects the truth of some mythical story. So that, without natural science, it is not possible to attain our pleasures unalloyed.
• PD13. There is no profit in securing protection in relation to men, if things above, and things beneath the earth, and indeed all in the boundless universe, remain matters of suspicion.
• Epicurus to Menoeceus - [123] The things which I used unceasingly to commend to you, these do and practice, considering them to be the first principles of the good life. First of all believe that god is a being immortal and blessed, even as the common idea of a god is engraved on men’s minds, and do not assign to him anything alien to his immortality or ill-suited to his blessedness: but believe about him everything that can uphold his blessedness and immortality. For gods there are, since the knowledge of them is by clear vision. But they are not such as the many believe them to be: for indeed they do not consistently represent them as they believe them to be. And the impious man is not he who popularly denies the gods of the many, but he who attaches to the gods the beliefs of the many. [124] For the statements of the many about the gods are not conceptions derived from sensation, but false suppositions, according to which the greatest misfortunes befall the wicked and the greatest blessings (the good) by the gift of the gods. For men being accustomed always to their own virtues welcome those like themselves, but regard all that is not of their nature as alien.
• Epicururus to Pythocles - [116] All these things, Pythocles, you must bear in mind; for thus you will escape in most things from superstition and will be enabled to understand what is akin to them. And most of all give yourself up to the study of the beginnings and of infinity and of the things akin to them, and also of the criteria of truth and of the feelings, and of the purpose for which we reason out these things. For these points when they are thoroughly studied will most easily enable you to understand the causes of the details. But those who have not thoroughly taken these things to heart could not rightly study them in themselves, nor have they made their own the reason for observing them.
• Epicurus to Herodotus - [81] And besides all these matters in general we must grasp this point, that the principal disturbance in the minds of men arises because they think that these celestial bodies are blessed and immortal, and yet have wills and actions and motives inconsistent with these attributes; and because they are always expecting or imagining some everlasting misery, such as is depicted in legends, or even fear the loss of feeling in death as though it would concern them themselves; and, again, because they are brought to this pass not by reasoned opinion, but rather by some irrational presentiment, and therefore, as they do not know the limits of pain, they suffer a disturbance equally great or even more extensive than if they had reached this belief by opinion. [82] But peace of mind is being delivered from all this, and having a constant memory of the general and most essential principles. Wherefore we must pay attention to internal feelings and to external sensations in general and in particular, according as the subject is general or particular, and to every immediate intuition in accordance with each of the standards of judgment. For if we pay attention to these, we shall rightly trace the causes whence arose our mental disturbance and fear, and, by learning the true causes of celestial phenomena and all other occurrences that come to pass from time to time, we shall free ourselves from all which produces the utmost fear in other men.
• Lucretius Book Six - [68] And unless you spew out all this from your mind and banish far away thoughts unworthy of the gods and alien to their peace, the holy powers of the gods, degraded by thy thought, will often do thee harm; not that the high majesty of the gods can be polluted by thee, so that in wrath they should yearn to seek sharp retribution, but because you yourself will imagine that those tranquil beings in their placid peace set tossing the great billows of wrath, nor with quiet breast will you approach the shrines of the gods, nor have strength to drink in with tranquil peace of mind the images which are borne from their holy body to herald their divine form to the minds of men. And therefore what manner of life will follow, you may perceive.

There is no absolute virtue, but practical virtue is instrumental for achieving pleasure.

...

Prudence

...

• Epicurus' Letter to Menoeceus - Of all this the beginning and the greatest good is prudence. Wherefore prudence is a more precious thing even than philosophy: for from prudence are sprung all the other virtues, and it teaches us that it is not possible to live pleasantly without living prudently and honorably and justly, (nor, again, to live a life of prudence, honor, and justice) without living pleasantly. For the virtues are by nature bound up with the pleasant life, and the pleasant life is inseparable from them.
• Cicero's Torquatus in On Ends Book 1 - XII - For as the chief annoyances to human life proceed from ignorance of what things are good and what bad, and as by reason of that mistake men are often deprived of the greatest pleasures, and tortured by the most bitter grief of mind, we have need to exercise wisdom, which, by removing groundless alarms and vain desires, and by banishing the rashness of all erroneous [pg 114] opinions, offers herself to us as the surest guide to pleasure. For it is wisdom alone which expels sorrow from our minds, and prevents our shuddering with fear: she is the instructress who enables us to live in tranquility, by extinguishing in us all vehemence of desire. For desires are insatiable, and ruin not only individuals but entire families, and often overturn the whole state. From desires arise hatred, dissensions, quarrels, seditions, wars. Nor is it only out of doors that these passions vent themselves, nor is it only against others that they run with blind violence; but they are often shut up, as it were, in the mind, and throw that into confusion with their disagreements.
• Cicero's Torquatus in On Ends Book 1 XIV - But if we see that the whole life of man is into disorder by error and ignorance; and that wisdom is the only thing which can relieve us from the sway of the passions and the fear of danger, and which can teach us to bear the injuries of fortune itself with moderation, and which shows us all the ways which lead to tranquility and peace; what reason is there that we should hesitate to say that wisdom is to be sought for the sake of pleasure, and that folly is to be avoided on account of its annoyances?

Friendship

...

• PD27 - Of all the things which wisdom acquires to produce the blessedness of the complete life, far the greatest is the possession of friendship.
• PD28 - The same knowledge that makes one confident that nothing dreadful is eternal or long-lasting also recognizes, in the face of these limited evils, the security afforded by friendship.
• VS23 - Every friendship is worth choosing for its own sake, though it takes its origin from the benefits.
• VS28 - We must not approve either those who are always ready for friendship, or those who hang back, but for friendship’s sake we must run risks.
• VS34 - It is not so much our friends' help that helps us, as it is the confidence of their help.
• VS39 - He is no friend who is continually asking for help, nor he who never associates help with friendship. For the former barters kindly feeling for a practical return, and the latter destroys the hope of good in the future.
• VS52 - Friendship dances around the world, bidding us all to awaken to the recognition of happiness.
• VS56 - The wise man feels no more pain, when being tortured himself than when his friend is tortured.
• VS57 - On occasion a man will die for his friend, for if he betrays his friend, his whole life will be confounded by distrust and completely upset.
• VS66 - Let us show our feeling for our lost friends, not by lamentation, but by meditation.
• VS78 - The truly noble man busies himself chiefly with wisdom and friendship, of which the one is an understandable good but the other is immortal.

Courage

...

• Diogenes Laertius X - 122 - They hold that ... courage does not come by nature, but by a calculation of advantage.
• Epicurus to Herotodus 83 - Here, Herodotus, is my treatise on the chief points concerning the nature of the general principles, abridged so that my account would be easy to grasp with accuracy. I think that, even if one were unable to proceed to all the detailed particulars of the system, he would from this obtain an unrivaled strength compared with other men. For indeed he will clear up for himself many of the detailed points by reference to our general system, and these very principles, if he stores them in his mind, will constantly aid him. For such is their character that even those who are at present engaged in working out the details to a considerable degree, or even completely, will be able to carry out the greater part of their investigations into the nature of the whole by conducting their analysis in reference to such a survey as this. And as for all who are not fully among those on the way to being perfected, some of them can from this summary obtain a hasty view of the most important matters without oral instruction so as to secure peace of mind.
• Cicero's Torquatus in On Ends Book 1 - XV - The same principle will be found to hold good with respect to courage. For the discharge of labours and the endurance of pain are neither of them intrinsically tempting; nor is patience, nor diligence, nor watchfulness, nor industry which is so much extolled, nor even courage itself: but we cultivate these habits in order that we may live without care and fear, and may be able, as far as is in our power, to release our minds and bodies from annoyance. For as the whole condition of tranquil life is thrown into confusion by the fear of death, and as it is a miserable thing to yield to pain and to bear it with a humble and imbecile mind; and as on account of that weakness of mind many men have ruined their parents, many men their friends, some their country, and very many indeed have utterly undone themselves; so a vigorous and lofty mind is free from all care and pain, since it despises death, which only places those who encounter it in [pg 116] the same condition as that in which they were before they were born; and it is so prepared for pain that it recollects that the very greatest are terminated by death, and that slight pains have many intervals of rest, and that we can master moderate ones, so as to bear them if they are tolerable, and if not, we can depart with equanimity out of life, just as out of a theatre, when it no longer pleases us. By all which considerations it is understood that cowardice and idleness are not blamed, and that courage and patience are not praised, for their own sakes; but that the one line of conduct is rejected as the parent of pain, and the other desired as the author of pleasure.

Justice

...

• PD31 - The justice which arises from nature is a pledge of mutual advantage, to restrain men from harming one another, and save them from being harmed.
• PD32 - For all living things which have not been able to make compacts not to harm one another, or be harmed, nothing ever is either just or unjust; and likewise, too, for all tribes of men which have been unable, or unwilling, to make compacts not to harm or be harmed.
• PD33 - Justice never is anything in itself, but in the dealings of men with one another, in any place whatever, and at any time, it is a kind of compact not to harm or be harmed.
• PD34 - Injustice is not an evil in itself, but only in consequence of the fear which attaches to the apprehension of being unable to escape those appointed to punish such actions.
• PD35 - It is not possible for one who acts in secret contravention of the terms of the compact not to harm or be harmed to be confident that he will escape detection, even if, at present, he escapes a thousand times. For up to the time of death it cannot be certain that he will indeed escape.
• PD36 - In its general aspect, justice is the same for all, for it is a kind of mutual advantage in the dealings of men with one another; but with reference to the individual peculiarities of a country, or any other circumstances, the same thing does not turn out to be just for all.
• PD37 - Among actions which are sanctioned as just by law, that which is proved, on examination, to be of advantage, in the requirements of men's dealings with one another, has the guarantee of justice, whether it is the same for all or not. But if a man makes a law, and it does not turn out to lead to advantage in men's dealings with each other, then it no longer has the essential nature of justice. And even if the advantage in the matter of justice shifts from one side to the other, but for a while accords with the general concept, it is nonetheless just for that period, in the eyes of those who do not confound themselves with empty sounds, but look to the actual facts.
• PD38 - Where, provided the circumstances have not been altered, actions which were considered just have been shown not to accord with the general concept, in actual practice, then they are not just. But where, when circumstances have changed, the same actions which were sanctioned as just no longer lead to advantage, they were just at the time, when they were of advantage for the dealings of fellow-citizens with one another, but subsequently they are no longer just, when no longer of advantage.

Honesty

...

• VS29 - For I would certainly prefer, as I study Nature, to announce frankly what is beneficial to all people, even if none agrees with me, rather than to compromise with common opinions, and thus reap the frequent praise of the many.
• VS54 - We must not pretend to study philosophy, but study it in reality, for it is not the appearance of health that we need, but real health.
• Diogenes Laertius - When once a man has attained wisdom, he no longer has any tendency contrary to it or willingly pretends that he has.

Confidence

...

• PD12 - A man cannot dispel his fear about the most important matters if he does not know what is the nature of the universe, but suspects the truth of some mythical story. So that, without natural science, it is not possible to attain our pleasures unalloyed.
• PD13 - There is no profit in securing protection in relation to men, if things above, and things beneath the earth, and indeed all in the boundless universe, remain matters of suspicion.
• VS34 - It is not so much our friends' help that helps us, as it is the confidence of their help.
• PD04 - As many as possess the power to procure complete immunity from their neighbors, these also live most pleasantly with one another, since they have the most certain pledge of security, and, after they have enjoyed the fullest intimacy, they do not lament the previous departure of a dead friend, as though he were to be pitied.
• Epicurus to Herotodus [83] - Here, Herodotus, is my treatise on the chief points concerning the nature of the general principles, abridged so that my account would be easy to grasp with accuracy. I think that, even if one were unable to proceed to all the detailed particulars of the system, he would from this obtain an unrivaled strength compared with other men. For indeed he will clear up for himself many of the detailed points by reference to our general system, and these very principles, if he stores them in his mind, will constantly aid him. For such is their character that even those who are at present engaged in working out the details to a considerable degree, or even completely, will be able to carry out the greater part of their investigations into the nature of the whole by conducting their analysis in reference to such a survey as this. And as for all who are not fully among those on the way to being perfected, some of them can from this summary obtain a hasty view of the most important matters without oral instruction so as to secure peace of mind.

Beneficence

...

• VS52 - Friendship dances around the world, bidding us all to awaken to the recognition of happiness.
• Diogenes of Oinoanda - Having already reached the sunset of my life (being almost on the verge of departure from the world on account of old age), I wanted, before being overtaken by death, to compose a [fine] anthem [to celebrate the] fullness [of pleasure] and so to help now those who are well-constituted. Now, if only one person or two or three or four or five or six or any larger number you choose, sir, provided that it is not very large, were in a bad predicament, I should address them individually and do all in my power to give them the best advice. But, as I have said before, the majority of people suffer from a common disease, as in a plague, with their false notions about things, and their number is increasing (for in mutual emulation they catch the disease from one another, like sheep) moreover, [it is] right to help [also] generations to come (for they too belong to us, though they are still unborn) and, besides, love of humanity prompts us to aid also the foreigners who come here. Now, since the remedies of the inscription reach a larger number of people, I wished to use this stoa to advertise publicly the [medicines] that bring salvation. These medicines we have put [fully] to the test; for we have dispelled the fears [that grip] us without justification, and, as for pains, those that are groundless we have completely excised, while those that are natural we have reduced to an absolute minimum, making their magnitude minute. ... So (to reiterate what I was saying) observing that these people are in this predicament, I bewailed their behaviour and wept over the wasting of their lives, and I considered it the responsibility of a good man to give [benevolent] assistance, to the utmost of one's ability, to those of them who are well-constituted. [This] is the first reason [for the inscription].

Temperance

...

Considerateness

...

Hope

...

• Epicurus to Menoeceus: We must then bear in mind that the future is neither ours, nor yet wholly not ours, so that we may not altogether expect it as sure to come, nor abandon hope of it, as if it will certainly not come.
• VS33. The flesh cries out to be saved from hunger, thirst, and cold. For if a man possess this safety, and hope to possess it, he might rival even Zeus in happiness.

Gratitude

...

• VS17 - It is not the young man who should be thought happy, but the old man who has lived a good life. For the young man at the height of his powers is unstable, and is carried this way and that by fortune, like a headlong stream. But the old man has come to anchor in old age, as though in port, and the good things for which before he hardly hoped he has brought into safe harbor in his grateful recollections.
• VS55 - We must heal our misfortunes by the grateful recollection of what has been, and by the recognition that it is impossible to undo that which has been done.
• VS67 - A free life cannot acquire many possessions, because this is not easy to do without servility to mobs or monarchs, yet it possesses all things in unfailing abundance; and if by chance it obtains many possessions, it is easy to distribute them so as to win the gratitude of neighbors.
• VS69 -. The ungrateful greed of the soul makes the creature everlastingly desire varieties in its lifestyle.
• VS75 - The saying, “look to the end of a long life,“ shows ungratefulness for past good fortune.
• U469 - Johannes Stobaeus, Anthology, XVII.23 - Thanks be to blessed Nature because she has made what is necessary easy to supply, and what is not easy unnecessary.

Living In The Present

...

• Epicurus to Menoeceus - And the man who says that the age for philosophy has either not yet come or has gone by is like the man who says that the age for happiness is not yet come to him, or has passed away.
• VS14 - We are born once and cannot be born twice, but for all time must be no more. But you, who are not master of tomorrow, postpone your happiness. Life is wasted in procrastination, and each one of us dies while occupied.
• VS30 - Some men, throughout their lives, spend their time gathering together the means of life, for they do not see that the draught swallowed by all of us at birth is a draught of death.

...

• PD27 - Of all the things which wisdom acquires to produce the blessedness of the complete life, far the greatest is the possession of friendship.
• Epicurus' Letter to Menoeceus - Meditate therefore on these things and things akin to them night and day by yourself; and with a companion like to yourself, and never shall you be disturbed waking or asleep, but you shall live like a god among men. For a man who lives among immortal blessings is not like unto a mortal being.
• Epicurus' Letter to Herodotus - Here, Herodotus, is my treatise on the chief points concerning the nature of the general principles, abridged so that my account would be easy to grasp with accuracy. I think that, even if one were unable to proceed to all the detailed particulars of the system, he would from this obtain an unrivaled strength compared with other men. For indeed he will clear up for himself many of the detailed points by reference to our general system, and these very principles, if he stores them in his mind, will constantly aid him.

And as for all who are not fully among those on the way to being perfected, some of them can from this summary obtain a hasty view of the most important matters without oral instruction so as to secure peace of mind.
• Epicurus' Letter to Pythocles - All these things, Pythocles, you must bear in mind; for thus you will escape in most things from superstition and will be enabled to understand what is akin to them. And most of all give yourself up to the study of the beginnings and of infinity and of the things akin to them, and also of the criteria of truth and of the feelings, and of the purpose for which we reason out these things. For these points when they are thoroughly studied will most easily enable you to understand the causes of the details. But those who have not thoroughly taken these things to heart could not rightly study them in themselves, nor have they made their own the reason for observing them.
• VS41 - We must laugh and philosophize at the same time, and do our household duties, and employ our other faculties, and never cease proclaiming the sayings of the true philosophy.

Remind yourself that supernatural gods do not exist. Gods did not create the universe and are not involved with humans, so gods are nothing to worry about.

...

• PD12 - A man cannot dispel his fear about the most important matters if he does not know what is the nature of the universe, but suspects the truth of some mythical story. So that, without natural science, it is not possible to attain our pleasures unalloyed. Epicurus' PD12
• PD13 - There is no profit in securing protection in relation to men, if things above, and things beneath the earth, and indeed all in the boundless universe, remain matters of suspicion.
• VS49 - It is impossible for someone to dispel his fears about the most important matters if he does not know the Nature of the universe, but still gives some credence to myths. So, without the study of Nature, there is no enjoyment of pure pleasure.

Remind yourself that you need not live forever to experience a full life. Pleasure has a limit in quantity; when all pain is eliminated, the quantity of pleasure does not increase, but only varies.

...

• PD03. The limit of quantity in pleasures is the removal of all that is painful. Wherever pleasure is present, as long as it is there, there is neither pain of body, nor of mind, nor of both at once.
• PD18. The pleasure in the flesh is not increased when once the pain due to want is removed, but is only varied: and the limit as regards pleasure in the mind is begotten by the reasoned understanding of these very pleasures, and of the emotions akin to them, which used to cause the greatest fear to the mind.
• PD19. Infinite time contains no greater pleasure than limited time, if one measures, by reason, the limits of pleasure.
• PD20. The flesh perceives the limits of pleasure as unlimited, and unlimited time is required to supply it. But the mind, having attained a reasoned understanding of the ultimate good of the flesh and its limits, and having dissipated the fears concerning the time to come, supplies us with the complete life, and we have no further need of infinite time; but neither does the mind shun pleasure, nor, when circumstances begin to bring about the departure from life, does it approach its end as though it fell short, in any way, of the best life.

Remind yourself that life is short and there is no life after death, so treasure your life and do not procrastinate in pursuing pleasure.

...

• PD02 - Death is nothing to us, for that which is dissolved is without sensation; and that which lacks sensation is nothing to us.
• VS10 - Remember that you are mortal, and have a limited time to live, and have devoted yourself to discussions on Nature for all time and eternity, and have seen “things that are now and are to come and have been.”
• VS14 - We are born once and cannot be born twice, but for all time must be no more. But you, who are not master of tomorrow, postpone your happiness. Life is wasted in procrastination, and each one of us dies while occupied.
• VS30 - Some men, throughout their lives, spend their time gathering together the means of life, for they do not see that the draught swallowed by all of us at birth is a draught of death.
• VS31 - Against all else it is possible to provide security, but as against death all of us, mortals alike, dwell in an unfortified city.
• VS38 - He is a little man in all respects who has many good reasons for quitting life.
• VS60 - Every man passes out of life as though he had just been born.

Remind yourself that unendurable pain is not to be feared. Pain is short if intense, endurable and offset by pleasure if long, and can always be escaped by death.

...

• PD04. Pain does not last continuously in the flesh, but the acutest pain is there for a very short time, and even that which just exceeds the pleasure in the flesh does not continue for many days at once. But chronic illnesses permit a predominance of pleasure over pain in the flesh.

Surround yourself, remember, and occupy your mind with things that bring you pleasure.

...

• VS18 - Remove sight, association, and contact, and the passion of love is at an end.
• VS19 - Forgetting the good that has been, he has become old this very day.
• VS55 - We must heal our misfortunes by the grateful recollection of what has been, and by the recognition that it is impossible to undo that which has been done.

Be honest and frank with yourself and your friends.

...

• VS29. For I would certainly prefer, as I study Nature, to announce frankly what is beneficial to all people, even if none agrees with me, rather than to compromise with common opinions, and thus reap the frequent praise of the many.

Become as self-sufficient and independent of the "crowd" - those who are not your friends - as reasonably possible, and do not err in being either too extravagant or too frugal.

...

• VS44 - The wise man, when he has accommodated himself to straits, knows better how to give than to receive, so great is the treasure of self-sufficiency which he has discovered.
• VS45 - The study of nature does not make men productive of boasting or bragging, nor apt to display that culture which is the object of rivalry with the many, but high-spirited and self-sufficient, taking pride in the good things of their own minds and not of their circumstances.
• VS58 - We must free ourselves from the prison of public education and politics.
• PD39 - The man who has best ordered the element of disquiet arising from external circumstances has made those things that he could akin to himself, and the rest at least not alien; but with all to which he could not do even this, he has refrained from mixing, and has expelled from his life all which it was of advantage to treat thus.
• PD40 - As many as possess the power to procure complete immunity from their neighbors, these also live most pleasantly with one another, since they have the most certain pledge of security, and, after they have enjoyed the fullest intimacy, they do not lament the previous departure of a dead friend, as though he were to be pitied.
• VS63. Frugality too has a limit, and the man who disregards it is like him who errs through excess.
• VS77. The greatest fruit of self-sufficiency is freedom.

Value prudence and live wisely.

...

• VS46. Let us utterly drive from us our bad habits, as if they were evil men who have long done us great harm.
• VS47. I have anticipated thee, Fortune, and I have closed off every one of your devious entrances. And we will not give ourselves up as captives, to thee or to any other circumstance; but when it is time for us to go, spitting contempt on life and on those who cling to it maundering, we will leave from life singing aloud a glorious triumph-song on how well we lived.
• VS48. We must try to make the end of the journey better than the beginning, as long as we are journeying; but when we come to the end, we must be happy and content.
• VS71. Every desire must be confronted by this question: What will happen to me if the object of my desire is accomplished, and what if it is not?
