Boehm, professor of anthropology and director of the Jane Goodall Research Center at the University of Southern California, ranges broadly in his quest to determine the evolutionary origins of social and political behavior. Combining an exhaustive ethnographic survey of human societies from groups of hunter-gatherers to contemporary residents of the Balkans with a detailed analysis of the behavioral attributes of nonhuman primates (chimpanzees, gorillas, bonobos), Boehm focuses on whether humans are hierarchical or egalitarian by nature. His thesis "is that egalitarianism does not result from the mere absence of hierarchy, as is commonly assumed. Rather egalitarianism involves a very special type of hierarchy, a curious type that is based on antihierarchical feelings." This "reverse dominance hierarchy," as Boehm calls it, depends on the rank and file banding together "to deliberately dominate their potential master if they wish to remain equal." Boehm extends his analysis to argue that the processes of group selection originally advanced by David Sloan Wilson can account for the evolution of altruistic behavior in humans. While Boehm's hypotheses are not always persuasive, they are invariably intriguing and well documented. His presentation can be difficult for the nonspecialist, but he raises topics of wide interest and his book should gain attention.

Derived from Thomas Nagel's Locke Lectures, Equality and Partiality proposes a nonutopian account of political legitimacy, based on the need to accommodate both personal and impersonal motives in any credible moral theory, and therefore in any political theory with a moral foundation. Within each individual, Nagel believes, there is a division between two standpoints, the personal and the impersonal. Without the impersonal standpoint, there would be no morality, only the clash, compromise, and occasional convergence of individual perspectives. It is because a human being does not occupy only his own point of view that each of us is susceptible to the claims of others through private and public morality. Political systems, to be legitimate, must achieve an integration of these two standpoints within the individual. These ideas are applied to specific problems such as social and economic inequality, toleration, international justice, and the public support of culture. Nagel points to the problem of balancing equality and partiality as the most important issue with which political theorists are now faced.
