This is a comprehensive survey of the anthropological study of human universals, human nature, culture vs. biology, etc. It's also a critique of the field of anthropology, and one given from a refreshing outside-looking-in perspective. Brown deals with several influential cases (such as Margaret Mead's study of Samoan adolescence) and shows where they erred. He discusses the processes of defining and demonstrating universals, takes us on a grand tour of the history of universals in anthropology, presents the basic gamut of how universals have been and can be explained. In the final chapters he lays out his position and leaves cultural relativism thoroughly refuted. Cultural relativists, he demonstrates, have relied on universals even in their attempts to show cultural relativity. Among even the most dissimilar human languages, for example, the similarities (grammar, syntax, rhythm, content, etc.) still far outweigh the differences. Anthropologists have historically focused on the differences while remaining blind to the (often more fundamental and important) similarities. I'm a little leery of some of the traits Brown ends up calling universal; he does acknowledge the "working" nature of such a list. But what precisely shall be found to be universal is less important than simply the shift to an orientation that would seek to understand human nature in such terms. This is what Brown proposes. He understands the place of anthropology in the social sciences, the field's potential, where and how that potential has gone unrealized, and how anthropologists will need to alter their approach if they're to be fruitful in the future. I haven't even scraped the surface here; the book is a gold mine of interdisciplinary connections and it brims with insights. More than anything, it's a sensible, biologically-informed, (dare I say) reality-based account of human nature. The tone is that of a genuine pursuit of truth, as opposed to the trend among some social scientists to search high and low for anything that supports established theory. This book is packed, and in many ways it only aims to lay the framework of a better approach to the subject.
