Abstract

In his book Survival of the Virtuous, Dennis Krebs explores the origins of human morality. His approach is decidedly evolutionary. Indeed, he contends that the key to understanding our moral nature is considering the adaptive functions of our moral traits. He does acknowledge the importance of cultural and psychological explanations in filling in some of the particulars, but he argues that such accounts can only get us so far if we want to understand the ultimate underpinnings of morality. We are moral beings because it was advantageous for our survival and reproductive fitness to cooperate, and thus it is through evolutionary explanations that we can best understand our moral nature.
