Altruism and Group Selection Ever since Darwin created his theory of evolution in the nineteenth century, and especially since the nineteen sixties, scientists and philosophers of science have been intensely debating whether and how selection occurs at the level of the group. The debates over group selection maintain their vitality for several reasons: because group selection may explain the evolution of altruism; because “altruistic” traits—traits

Aristotle: Biology Aristotle (384-322 B.C.E.) may be said to be the first biologist in the Western tradition.

Modern Morality and Ancient Ethics It is commonly supposed that there is a vital difference between ancient ethics and modern morality. For example, there appears to be a vital difference between virtue ethics and the modern moralities of deontological ethics (Kantianism) and consequentialism (utilitarianism).
