Evolutionary ethics has a bad reputation. But we must not remain prisoners of our past. Recent advances in Darwinian evolutionary biology pave the way for a linking of science and morality, at once more modest yet more profound than earlier excursions in this direction. There is no need to repudiate the insights of the great philosophers of the past, particularly David Hume. So humans’ simian origins really matter. The question is not whether evolution is to be linked to ethics, but (...) how. (shrink)

Hopes of applying the findings and speculations of evolutionary theorizing to the problems of ethics have yielded a program with a bad reputation. At the level of norms – substantival ethics – it has been a platform for some of the more grotesque socio-politico-economic suggestions of our times. At the level of justification – metaethics – it has opened the way to some of the more blatant fallacies in the undergraduate textbook. Recently, however, a number of people, philosophers and biologists, (...) have sensed that a more adequate evolutionary ethics might be possible. United in the conviction that it simply has to matter that we humans are modified monkeys rather than the creation of a Good God, in His image, on the Sixth Day, they argue that recent developments in evolutionary biology, especially those dealing with the genetic basis of social behavior, open the way to a satisfactory biological understanding of morality.

This paper shows how the last twenty-five years of vocal human Darwinism (human sociobiology and evolutionary psychology) directly rejects the ‘selfish gene’ theory it is supposedly based upon. ‘Evangelistic sociobiology’, as Dawkins has called it, argues that humans evolved to be ‘the altruistic ape’. Using selfish gene theory this paper shows that we are born just another selfish ape. Given the ‘gross immorality’ (George Williams) of natural selection, one implication is that modern genetics has yet to face up to our (...) true genetic code. The ultimate conclusion of this paper is that culture makes civilisation possible because it overwrites, or ‘manipulates’, our genetic heritage. We are born ape, but made human. (shrink)

Robert Richards has presented a detailed defense of evolutionary ethics, a revised version of Darwin's views and a major modification of E. O. Wilson's. He contends that humans have evolved to seek the community welfare by acting altruistically. And since the community welfare is the highest moral good, humans ought to act altruistically. Richards asks us to take his empirical premises on faith and aims to show how they can justify an ethical conclusion. He identifies two necessary conditions for a (...) naturalistic justification of morality (NJ): its premises (1) must be empirical and (2) concerned with morally relevant causal factors. I argue that these two conditions are insufficient. An NJ must also appeal to teleogical or teleonomic laws which identify proper effects and reliable causes of these effects. So I supplement biological faith with an NJ that I believe has a better chance of working since faith without works is dead. (shrink)

A familiar position regarding the evolution of ethics is that biology can explain the origin of morals but that in doing so it removes the possibility of their having objective justification. This position is set fourth in detail in the writings of Michael Ruse but it is also taken by many others, notably, Jeffrie Murphy, Andrew Oldenquist, and Allan Gibbard, I argue the contrary view that biology provides a justification of the existence of morals which is objective in the sense (...) of being independent of people's moral views and their particular desires and preferences. Ironically, my argument builds on the very premises which are supposed to undermine the objectivity of morals. But my argument stops short of claiming that biology can give us a basis for justifying some particular system of morals. Drawing on an analogy with social contract theory, I offer a general reason why this more ambitious project cannot be expected to succeed if the argument is pursued along the same lines. Finally, I give reasons why the possibility of objective justification for a particular morality cannot be ruled out in general on evolutionary grounds. (shrink)

The second word in the subtitle of this article is crucial. For there can be no doubt but that the possibility of sociobiology below the human level has already been abundantly realized in, for instance, the main body of E. O. Wilson's enormous and encyclopedic treatise Sociobiology: The New Synthesis. What may more reasonably be doubted, and what is in fact questioned here, is whether, as Wilson and others hope and believe, there is much room, or indeed any, for a (...) sociobiology of our own notoriously wayward and idiosyncratic species. In proposing this particular project Wilson and his colleagues have seen themselves as promoting a climactic conquest for evolutionary biology. For surely, they seem to have thought, now, more than a century after Darwin, it is high time and past time to launch the final assault upon the last citadel. But, as we shall proceed to argue, there are reasons—reasons which were available at least in outline even to Darwin himself—why the ideas which have been so triumphantly successful in explaining The Origin of Species cannot properly be applied to what is in truth a fundamentally different task. They cannot, that is to say, properly be transferred to explain developments either within or out of the particular problem species of which the author of that book, along with both all the authors and all the readers of all other books, have been themselves members.

This book shows how Darwinian biology supports an Aristotelian view of ethics as rooted in human nature. Defending a conception of "Darwinian natural right" based on the claim that the good is the desirable, the author argues that there are at least twenty natural desires that are universal to all human societies because they are based in human biology. The satisfaction of these natural desires constitutes a universal standard for judging social practice as either fulfilling or frustrating human nature, although (...) prudence is required in judging what is best for particular circumstances. -/- The author studies the familial bonding of parents and children and the conjugal bonding of men and women as illustrating social behavior that conforms to Darwinian natural right. He also studies slavery and psychopathy as illustrating social behavior that contradicts Darwinian natural right. He argues as well that the natural moral sense does not require religious belief, although such belief can sometimes reinforce the dictates of nature. (shrink)

Though I have not found enough of the latter to test out this bromide, I am sensible of the value bestowed by colleagues who have taken such exacting care in analyzing my arguments. While their incisive observation and hard objections threaten to leave an extinct theory, I hope the reader will rather judge it one strengthened by adversity. Let me initially expose the heart of my argument so as to make obvious the shocks it must endure. I ask the reader (...) to grant that altruistic behavior can be empirically justified, that is, to allow that we have evolved under the aegis of kin and group selection (or comparably effective mechanisms) to heed the community welfare, to be moved to aid the distressed even at..

We propose an objective and justifiable ethics that is contingent on the truth of evolutionary theory. We do not argue for the truth of this position, which depends on the empirical question of whether moral functions form a natural class, but for its cogency and possibility. The position we propose combines the advantages of Kantian objectivity with the explanatory and motivational advantages of moral naturalism. It avoids problems with the epistemological inaccessibility of transcendent values, while avoiding the relativism or subjectivism (...) often associated with moral naturalism. Our position emerges out of criticisms of the contemporary sociobiological views of morality found in the writings of Richard Alexander, Michael Ruse, and Robert Richards. (shrink)
