Moral Darwinism: Ethical evidence for the descent of man (original) (raw)

1995, Biology & Philosophy

Could an ethical theory ever play a substantial evidential role in a scientific argument for an empirical hypothesis? InThe Descent of Man, Darwin includes an extended discussion of the nature of human morality, and the ethical theory which he sketches is not simply developed as an interesting ramification of his theory of evolution, but is used as a key part of his evidence for human descent from animal ancestors. Darwin must rebut the argument that, because of our moral nature, humans are essentially different in kind from other animals and so had to have had a different origin. I trace his causal story of how the moral sense could develop out of social instincts by evolutionary mechanisms of group selection, and show that the form of Utilitarianism he proposes involves a radical reduction of the standard of value to the concept of biological fitness. I argue that this causal analysis, although a weakness from a normative standpoint, is a strength when judged for its intended purpose as part of an evidential argument to confirm the hypothesis of human descent.

The Prospects for Evolutionary Ethics Today

One reason for the widespread resistance to evolutionary accounts of the origins of humanity is the fear that they undermine morality: if morality is based on nothing more than evolved dispositions, it would be shown to be illusory, many people suspect. This view is shared by some philosophers who take their work on the evolutionary origins of morality to undermine moral realism. If they are right, we are faced with an unpalatable choice: to reject morality on scientific grounds, or to reject our best-confirmed scientific explanation of our origins in order to save morality. Fortunately, as I show, we have no reason to accept the deflationary claims of some evolutionary ethicists: morality, as we ordinarily understand it, is fully compatible with evolution.

Founding Moral Reasoning on Evolutionary Psychology

The Ruffin Series of the Society for Business Ethics, 2004

In this paper I develop a critique of the strong adaptationist view inherent in the work of Leda Cosmides and John Tooby, as presentedat the Ruffin Lectures series in 2002. My critique proceeds in two stages. In the first stage, I advance arguments as to why I find the particular adaptation story that the authors advance for their experimental results unpersuasive even when I fully accept the value of their experimental results. In the second stage, I grant them their adaptation story and critique the implications of such stories forbusiness ethics and for future research. In sum, I argue against recasting key problems in the social sciences to fit the use of toolsdeveloped in the so-called “hard” sciences. Instead, I urge that we deal with these problems on their own terms, i.e. through their basisin and dependence on deliberate social action.
