Principles of right and wrong guide the lives of almost all human beings, but we often see them as external to ourselves, outside our own control. In a revolutionary approach to the problems of moral philosophy, 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.

Drawing on natural science, social science, and philosophy to develop an approach he calls "pragmatic naturalism," Kitcher reveals the power of an evolving ethics built around a few core principles-including justice and cooperation-but leaving room for a diversity of communities and modes of self-expression. Ethics emerges as a beautifully human phenomenon-permanently unfinished, collectively refined and distorted generation by generation. Our human values, Kitcher shows, can be understood not as a final system but as a project-the ethical project-in which our species has engaged for most of its history, and which has been central to who we are.

To observe a dog's guilty look.

to witness a gorilla's self-sacrifice for a wounded mate, to watch an elephant herd's communal effort on behalf of a stranded calf--to catch animals in certain acts is to wonder what moves them. Might there he a code of ethics in the animal kingdom? Must an animal be human to he humane? In this provocative book, a renowned scientist takes on those who have declared ethics uniquely human Making a compelling case for a morality grounded in biology, he shows how ethical behavior is as much a matter of evolution as any other trait, in humans and animals alike.

World famous for his brilliant descriptions of Machiavellian power plays among chimpanzees-the nastier side of animal life--Frans de Waal here contends that animals have a nice side as well. Making his case through vivid anecdotes drawn from his work with apes and monkeys and holstered by the intriguing, voluminous data from his and others' ongoing research, de Waal shows us that many of the building blocks of morality are natural: they can he observed in other animals. Through his eyes, we see how not just primates but all kinds of animals, from marine mammals to dogs, respond to social rules, help each other, share food, resolve conflict to mutual satisfaction, even develop a crude sense of justice and fairness.

Natural selection may be harsh, but it has produced highly successful species that survive through cooperation and mutual assistance. De Waal identifies this paradox as the key to an evolutionary account of morality, and demonstrates that human morality could never have developed without the foundation of fellow feeling our species shares with other animals. As his work makes clear, a morality grounded in biology leads to an entirely different conception of what it means to he human--and humane.

A Natural History of Human Morality offers the most detailed account to date of the evolution of human moral psychology. Based on extensive experimental data comparing great apes and human children, Michael Tomasello reconstructs how early humans gradually became an ultra-cooperative and, eventually, a moral species.

“Tomasello is convincing, above all, because he has run many of the relevant studies (on chimps, bonobos and children) himself. He concludes by emphasizing the powerful influence of broad cultural groups on modern humans… Tomasello also makes an endearing guide, appearing happily amazed that morality exists at all.”
—Michael Bond, New Scientist

“Most evolutionary theories picture humans as amoral ‘monads’ motivated by self-interest. Tomasello presents an innovative and well-researched, hypothesized natural history of two key evolutionary steps leading to full-blown morality.”
