Michael Tomasello offers the most detailed account to date of the evolution of human moral psychology. Based on experimental data comparing great apes and human children, he reconstructs two key evolutionary steps whereby early humans gradually became an ultra-cooperative and, eventually, a moral species capable of acting as a plural agent “we”.

Tool-making or culture, language or religious belief: ever since Darwin, thinkers have struggled to identify what fundamentally differentiates human beings from other animals. Michael Tomasello weaves his twenty years of comparative studies of humans and great apes into a compelling argument that cooperative social interaction is the key to our cognitive uniqueness. Tomasello maintains that our prehuman ancestors, like today's great apes, were social beings who could solve problems by thinking. But they were almost entirely competitive, aiming only at their individual goals. As ecological changes forced them into more cooperative living arrangements, early humans had to coordinate their actions and communicate their thoughts with collaborative partners. Tomasello's "shared intentionality hypothesis" captures how these more socially complex forms of life led to more conceptually complex forms of thinking. In order to survive, humans had to learn to see the world from multiple social perspectives, to draw socially recursive inferences, and to monitor their own thinking via the normative standards of the group. Even language and culture arose from the preexisting need to work together and coordinate thoughts. A Natural History of Human Thinking is the most detailed scientific analysis to date of the connection between human sociality and cognition.

Moral thinking pervades our practical lives, but where did this way of thinking come from, and what purpose does it serve? Is it to be explained by environmental pressures on our ancestors a million years ago, or is it a cultural invention of more recent origin? In The Evolution of Morality, Richard Joyce takes up these controversial questions, finding that the evidence supports an innate basis to human morality. As a moral philosopher, Joyce is interested in whether any implications follow from this hypothesis. Might the fact that the human brain has been biologically prepared by natural selection to engage in moral judgment serve in some sense to vindicate this way of thinking—staving off the threat of moral skepticism, or even undergirding some version of moral realism? Or if morality has an adaptive explanation in genetic terms—if it is, as Joyce writes, "just something that helped our ancestors make more babies"—might such an explanation actually undermine morality's central role in our lives? He carefully examines both the evolutionary "vindication of morality" and the evolutionary "debunking of morality," considering the skeptical view more seriously than have others who have treated the subject. Interdisciplinary and combining the latest results from the empirical sciences with philosophical discussion, The Evolution of Morality is one of the few books in this area written from the perspective of moral philosophy. Concise and without technical jargon, the arguments are rigorous but accessible to readers from different academic backgrounds. Joyce discusses complex issues in plain language while advocating subtle and sometimes radical views. The Evolution of Morality lays the philosophical foundations for further research into the biological understanding of human morality.

What is morality and what is the source of our moral ideas? Philosophers have explored these questions for centuries, suggesting that both emotion and reason play roles but failing to explain how and why Homo sapiens developed these ideas. Author Roger Moseley argues that evolutionary forces that optimize human welfare provide the missing explanation. Morality: A Natural History presents a multi-disciplinary analysis of the topic and reveals a common thread among the seemingly diverse fields of religion, neuroscience, experimental psychology and game theory, child development, evolution and animal behavior, and anthropology and sociology. When humans first appeared, a simple self-interested survival morality sufficed. As societies became more complex, however, rules of behavior became necessary to limit conflict and promote cooperation. The brain evolved, producing language that allowed the articulation of moral ideas which were codified and enforced by religion and social forces. No species lasts forever, and it is at our peril today that we neglect those evolved moral values of cooperation, altruism, truthfulness, and empathy. Rooted in scientific evidence and interspersed with personal anecdotes and humorous observations, Moseley provides a unique perspective on the natural history of morality – how it appeared, evolved, and continues to evolve today. Morality: A Natural History is essential reading for academics and laypersons alike who seek to understand the origin and essence of human morality.

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.

Winner of the William James Book Award “Magisterial...Makes an impressive argument that most distinctly human traits are established early in childhood and that the general chronology in which these traits appear can at least—and at last—be identified.” —Wall Street Journal “Theoretically daring and experimentally ingenious, Becoming Human squarely tackles the abiding question of what makes us human.” —Susan Gelman, University of Michigan Virtually all theories of how humans have become such a distinctive species focus on evolution. Becoming Human proposes a complementary theory of human uniqueness, focused on development. Building on the seminal ideas of Vygotsky, it explains how those things that make us most human are constructed during the first years of a child’s life. In this groundbreaking work, Michael Tomasello draws from three decades of experimental research with chimpanzees, bonobos, and children to propose a new framework for psychological growth between birth and seven years of age. He identifies eight pathways that differentiate humans from their primate relatives: social cognition, communication, cultural learning, cooperative thinking, collaboration, prosociality, social norms, and moral identity. In each of these, great apes possess rudimentary abilities, but the maturation of humans’ evolved capacities for shared intentionality transform these abilities into uniquely human cognition and sociality.
