These are moral claims about how to relate to people, given that they are different. But does it also matter whether we are different in the first place? I argue for the intrinsic value to us of individuality, understood in terms of our differences from others. Past defences of individuality often unhelpfully conflate it with autonomy or authenticity, but these can come apart from individuality. Individuality is also distinct from numerical identity and moral status, and cannot be fully captured in terms of rarity, diversity, or irreplaceability. Most current theories of well-being leave it open that lives utterly lacking in individuality might be wonderfully good. These theories, I argue, fail to account for what Valéry called ‘the evil of not being unique’.

I argue that when we take this into account, then it is likely that when the first humans appeared, the world was already at an enormous axiological deficit, and that even on favorable assumptions about humanity, it is doubtful that we have overturned this deficit or ever will. Even if there's no such deficit or we can overturn it, it remains the case that everything of value associated with humanity was made possible by our evolutionary history and all that animal suffering. It can seem indecent to regard all that past suffering as having been worth it simply because it was a causal precondition for our existence. But when we consider the realistic alternatives to the way evolution in fact unfolded, there is nevertheless a conditional case for regarding past sentient suffering as a kind of necessary evil.

Is such moral anthropocentrism based in perceived differences in mental capacity between humans and non-humans or merely because humans favor other members of their own species? We investigated this question in six studies (N = 2,217). We found that most participants prioritized humans over animals even when the animals were described as having equal or more advanced mental capacities than the humans. This applied to both mental capacity at the level of specific individuals (Studies 1a-b) and at the level typical for the respective species (Study 2). The key driver behind moral anthropocentrism was thus mere species-membership (speciesism). However, all else equal, participants still gave more moral weight to individuals with higher mental capacities (individual mental capacity principle), suggesting that the belief that humans have higher mental capacities than animals is part of the reason that they give humans moral ...

But doesn't this commit atheists to wishing that God did exist, and to the pro-theist view that the world would have been better had God existed? This doesn't follow. I argue that if all that evil still remains but is just no longer gratuitous, then, from an atheist perspective, that wouldn't have been better. And while a counterfactual from which that evil is literally absent would have been impersonally better, it wouldn't have been better for anyone, including for those who suffered such evils.

In recent years, there has been increasing interest in such a hybrid views of ethics. Discussions of this Nozickian Hybrid View, and similar approaches to animal ethics, often assume that such an approach reflects the commonsense view, and best captures common moral intuitions. However, recent psychological work challenges this empirical assumption. We review evidence suggesting that the folk is deontological all the way down-it is just that the moral side constraints that protect animals from harm are much weaker than those that protect humans. In fact, it appears that people even attribute some deontological protections, albeit extremely weak ones, to inanimate objects. We call this view Multi-level Weighted Deontology. While such empirical findings cannot show that the Nozickian Hybrid View is false, or that it is unjustified, they do remove its core intuitive support. That support belongs to Multi-level Weighted Deontology, a view that is also in line with the view that Nozick himself seemed to favour. To complicate things, however, we also review evidence that our intuitions about the moral status of humans are, at least in significant part, shaped by factors relating to mere species membership that seem morally irrelevant. We end by considering the potential debunking upshot of such findings about the sources of common moral intuitions about the moral status of animals.

But it’s unclear what it means to describe the universe as indifferent, or what a non-indifferent universe would be like. I suggest that the relevant contrast isn’t simply that between God and His absence, nor is the complaint about indifference focused on the lack of a kind of cosmic concern. At its heart is the idea of a mismatch between world and value. Although the causal forces governing our world are ‘blind’, they nevertheless do partly align with value. Still, our world is so arranged that senseless suffering is depressingly common, and the rosy non-indifferent counterfactual won’t contain such evil. I argue, however, that it is a mistake to long for such an alternative: it must either involve an upside-down moral order, or would be a world from which we, and those who senselessly suffer, will be absent.

What is the relationship between meaning in life and importance? Because both can be described as relating to significance, the two are often conflated. But these are rather different concepts and the meaningful and the important can easily come apart. They do, however, interact in important ways. When importance also meets the conditions for meaningfulness, it amplifies it, and importance on a large scale is a key, and perhaps the only, source of superlative meaningfulness. When contrasted with the quest for meaning, the desire for importance can seem shallow and egocentric. But the desire to make an important contribution reflects a legitimate existential concern. And, in their best form, both the desire for importance, and that for meaningfulness, similarly combine outward-looking and self-regarding aspects.

Many hold, however, that anti-theism is incoherent if we assume that God would not permit gratuitous evil to occur. This is because that would entail that any alleged downsides of God's existence would be permitted only if they are necessary to bring about a greater good or to prevent an even greater evil. I will argue that this emerging consensus is mistaken: the argument from the principle of non-gratuitous evil to the falsity of anti-theism is invalid because it trades on an ambiguity. Appealing directly to God's perfect goodness fails for similar reasons. Anti-theism can therefore only be rejected via substantive axiological debate.

Some crave fame, or at least wide recognition. And some even desire glory that will only be realised after their death. Such desires are either ignored or disparaged by many philosophers. I argue, however, that although few of us have a real shot at importance and fame on any grand scale, these can be genuine personal goods when they meet certain further conditions. Importance that relates to positive impact and reflects our agency answers a distinctive existential concern for one's life, and existence, to matter. And since what is important merits wide appreciation, the step from wanting to be significant and wanting that significance fittingly and widely appreciated is small. Still, desires for importance and fame can take a more vicious character when they are not properly structured, and when they are not dominated by more impartial aims. If we accept the personal value of importance and fame, it is hard to see why that value cannot extend beyond our death; the temporal distribution of glory is actually irrelevant to its value. It is therefore a mistake to identify a concern with posthumous glory with the wish to leave a trace after our death.

B... more Many believe that because we’re so small, we must be utterly insignificant on the cosmic scale. But whether this is so depends on what it takes to be important. On one view, what matters for importance is the difference to value that something makes. On this view, what determines our cosmic importance isn’t our size, but what else of value is out there. But a rival view also seems plausible: that importance requires sufficient causal impact on the relevant scale; since we have no such impact on the grand scale, that would entail our cosmic insignificance. I argue that despite appearances, causal impact is neither necessary nor sufficient for importance. All that matters is impact on value. Since parts can have non-causal impact on the value of the wholes that contain them, this means that we might have great impact on the grandest scale without ever leaving our little planet.

I argue that even if atheism was incompatible with existential optimism in this way, this presents no threat to atheism. Moreover, it's unclear how the suffering associated with evolution could on its own undermine existential optimism. Links between Nagasawa argument and the current debate about the axiology of (a)theism are also explored.

But our concern about history can seem puzzling, and needs justification. After all, the past cannot be changed: we can help the living needy, but the tears we shed for the long dead victims of past tragedies help no one. Attempts to justify our concern about history typically take one of two opposing forms. It is assumed either that such concern must be justified in instrumental or otherwise self- and present-centered terms, or that our interest in history must be utterly disinterested, and pursued for its own sake. But neither approach can fully explain, or justify, our concern about the past. I propose a third approach, on which the past matters because it contains much that is of value—all those past people, and the things they did, or had endured—and this value calls for our fitting response. In short: the significance of the past is past significance.

Do... more Most people hold that it is wrong to sacrifice some humans to save a greater number of humans. Do people also think that it is wrong to sacrifice some animals to save a greater number of animals, or do they answer such questions about harm to animals by engaging in a utilitarian cost-benefit calculation? Across 10 studies (N = 4,662), using hypothetical and real-life sacrificial moral dilemmas, we found that participants considered it more permissible to harm a few animals to save a greater number of animals than to harm a few humans to save a greater number of humans. This was explained by a reduced general aversion to harm animals compared to humans, which was partly driven by participants perceiving animals to suffer less and to have lower cognitive capacity than humans. However, the effect persisted even in cases where animals were described as having greater suffering capacity and greater cognitive capacity than some humans, and even when participants felt more socially connected to animals than to humans. The reduced aversion to harming animals was thus also partly due to speciesism—the tendency to ascribe lower moral value to animals due to their species-membership alone. In sum, our studies show that deontological constraints against instrumental harm are not absolute but get weaker the less people morally value the respective entity. These constraints are strongest for humans, followed by dogs, chimpanzees, pigs, and finally inanimate objects.

In two pre-registered studies (N = 622), 5- to 9-year-old children and adults were presented with moral dilemmas pitting varying numbers of humans against varying numbers of either dogs or pigs and were asked who should be saved. In both studies, children had a weaker tendency to prioritize humans over animals than adults. They often chose to save multiple dogs over one human, and many valued the life of a dog as much as the life of a human. While they valued pigs less, the majority still prioritized ten pigs over one human. By contrast, almost all adults chose to save one human over even one hundred dogs or pigs. Our findings suggest that the common view that humans are far more morally important than animals appears late in development and is likely socially acquired.

But to what extent can responses to sacrificial dilemmas shed light on utilitarian decision making? We consider two key questions: First, how meaningful is the relationship between responses to sacrificial dilemmas and what is distinctive of a utilitarian approach to morality? Second, to what extent do findings about sacrificial dilemmas generalise to other moral contexts where there is tension between utilitarianism and common-sense intuitions? We argue that sacrificial dilemmas only capture one point of conflict between utilitarianism and common-sense morality, and new paradigms are needed to investigate other key aspects of utilitarianism, such as its radical impartiality.

This simple point is routinely overlooked by familiar attitudes and evaluative judgments about the past, even those of sophisticated historians. I shall argue, however, that it means that when we feel sadness about some historical tragedy, or think of one possible course of history as better than another, these judgments and attitudes can be understood in terms of two opposing perspectives on the past: an impersonal standpoint concerned only with how much value each course of history contains, and a person-centred standpoint concerned with harms and benefits to the people who had actually existed. In this paper, I will set out these radically different visions of what matters in history and point out some of their surprising implications.

The prospects of prudential arguments that aim to show that God doesn't exist seem to me dim. But I will consider whether prudential considerations can give us pragmatic reasons for not believing that God exists. I will also consider how prudential considerations can figure in debunking arguments against theist belief. I will then turn to the question of whether we should want God to exist. In answering this question, I will consider a further kind of prudential argument-an argument that moves from claims about what would follow from God's existence or non-existence, to prudential conclusions. In particular, I will consider axiological arguments purporting to show that God's existence would make our lives worse. I will end by briefly considering questions relating to nihilism, meaning, and significance.

This research has generated important insights into people’s attitudes toward instrumental harm—that is, the sacrifice of an individual to save a greater number. But this approach also has serious limitations. Most notably, it ignores the positive, altruistic core of utilitarianism, which is characterized by impartial concern for the well-being of everyone, whether near or far. Here, we develop, refine, and validate a new scale—the Oxford Utilitarianism Scale—to dissociate individual differences in the ‘negative’ (permissive attitude toward instrumental harm) and ‘positive’ (impartial concern for the greater good) dimensions of utilitarian thinking as manifested in the general population. We show that these are two independent dimensions of proto-utilitarian tendencies in the lay population, each exhibiting a distinct psychological profile. Empathic concern, identification with the whole of humanity, and concern for future generations were positively associated with impartial beneficence but negatively associated with instrumental harm; and although instrumental harm was associated with subclinical psychopathy, impartial beneficence was associated with higher religiosity. Importantly, although these two dimensions were independent in the lay population, they were closely associated in a sample of moral philosophers. Acknowledging this dissociation between the instrumental harm and impartial beneficence components of utilitarian thinking in ordinary people can clarify existing debates about the nature of moral psychology and its relation to moral philosophy as well as generate fruitful avenues for further research.

They long for the world described by traditional religion. They do not believe in God, but they wish He had existed. I argue that this is a mistake. The naturalist world we inhabit is admittedly rather bleak. It is very far from being the best of all possible worlds. But an alternative governed by God is also unwelcome, and the things that might make God’s existence attractive—cosmic justice or the afterlife—could also be had without God. The most desirable of all possible worlds are therefore godless.

In particular, I will consider axiological arguments purporting to show that God's existence would make our lives worse. I will end by briefly considering questions relating to nihilism, meaning, and significance.

This research has generated important insights into people’s attitudes toward instrumental harm—that is, the sacrifice of an individual to save a greater number. But this approach also has serious limitations. Most notably, it ignores the positive, altruistic core of utilitarianism, which is characterized by impartial concern for the well-being of everyone, whether near or far. Here, we develop, refine, and validate a new scale—the Oxford Utilitarianism Scale—to dissociate individual differences in the ‘negative’ (permissive attitude toward instrumental harm) and ‘positive’ (impartial concern for the greater good) dimensions of utilitarian thinking as manifested in the general population. We show that these are two independent dimensions of proto-utilitarian tendencies in the lay population, each exhibiting a distinct psychological profile. Empathic concern, identification with the whole of humanity, and concern for future generations were positively associated with impartial beneficence but negatively associated with instrumental harm; and although instrumental harm was associated with subclinical psychopathy, impartial beneficence was associated with higher religiosity. Importantly, although these two dimensions were independent in the lay population, they were closely associated in a sample of moral philosophers. Acknowledging this dissociation between the instrumental harm and impartial beneficence components of utilitarian thinking in ordinary people can clarify existing debates about the nature of moral psychology and its relation to moral philosophy as well as generate fruitful avenues for further research.

Does God Matter? Essays on the Axiological Consequences of Theism, 2018

They long for the world described by traditional religion. They do not believe in God, but they wish He had existed. I argue that this is a mistake. The naturalist world we inhabit is admittedly rather bleak. It is very far from being the best of all possible worlds. But an alternative governed by God is also unwelcome, and the things that might make God’s existence attractive—cosmic justice or the afterlife—could also be had without God. The most desirable of all possible worlds are therefore godless.
