Behave: The Biology of Humans at our Best and Worst by Robert M. Sapolsky

Book – It’s the fundamental question of the biological and social sciences — why do humans do the things they do? Every discipline has its own answers, from the complex chemical interactions of neurobiology to the deep history of evolution. In Behave, Sapolsky pulls together all of these and more to explore the causes and meanings of human behavior, with an eye toward the most important question of all: How can we be better people?

This book is long, hard going, but it’s well worth it – it’s one of the only books on neuroscience I’ve ever read where the author doesn’t treat the core biological mechanics of neurochemicals and genes as though that provides a meaningful answer to any question. Rather, Sapolsky goes into detail about the interaction between genes, hormones, biochemistry, environment, and long-lasting biological change, making it clear that while there’s a biological explanation for everything, there are so many variables involved that saying we can identify a single source of any given human behavior is laughable at best. The book really gets good in the second half, when he starts to apply all this to the things we’re really concerned about – compassion and generosity, violence and aggression. Sapolsky is optimistic overall, but he makes it clear that improving society is going to mean fighting our biology in some ways (or, more effectively, learning how to trick it).

About Jen

I'm an Adult Services Librarian at the Warrenville Public Library. I'll read just about anything you put in front of me, but I've always been a science fiction & fantasy fan. I'm also fond of history, true crime, thrillers, and popular anthropology that isn't written by Jared Diamond. When I'm not reading, I'm painting, watching movies from the 1930s and 40s, working on my novel, or out at the archery range playing with pointy sticks.
