"A Cooperative Species is a fresh and pioneering entry into the pivotal field of human social evolution."--Edward O. Wilson, Harvard University

"In A Cooperative Species, Bowles and Gintis draw on their own research and teaching about understanding the complex human being in the context of diverse ways of organizing life. They show that humans can evolve cooperative strategies when they participate in groups that share long-term similar norms and are willing to sanction those that do not follow group agreements. An important book for all social scientists."--Elinor Ostrom, Nobel Laureate in Economics

"Why we form cooperative societies is not hard to understand given all of the advantages we derive, but how we do it is far less understood. Humans have powerful selfish tendencies, but Bowles and Gintis are not of the school of thought that everything can be reduced to selfishness. They muster all of their expert knowledge to make clear that evolution has produced a species with a truly cooperative spirit and the means to encourage cooperation in others."--Frans de Waal, author of The Age of Empathy

"Bowles and Gintis stress that cooperation among individuals who are only distantly related is a critical distinguishing feature of the human species. They argue forcefully that the best explanation for such cooperation is altruism. Many will dispute this claim, but it deserves serious consideration."--Eric Maskin, Nobel Laureate in Economics
