Philip Kitcher makes a provocative proposal: Instead of conceiving ethical commands as divine revelations or as the discoveries of brilliant thinkers, we should see our ethical practices as evolving over tens of thousands of years, as members of our species have worked out how to live together and prosper. Elaborating this radical new vision, Kitcher shows how the limited altruistic tendencies of our ancestors enabled a fragile social life, how our forebears learned to regulate their interactions with one another, and how human societies eventually grew into forms of previously unimaginable complexity. The most successful of the many millennia-old experiments in how to live, he contends, survive in our values today.
