Buller, a philosopher of science, takes on evolutionary psychology, arguing that the conventional wisdom of the field is misguided: human minds are not adapted to the Pleistocene; rather, they are continually adapting, both over evolutionary time and within individual lifetimes. Elliott Sober writes, "Buller's critique of evolutionary psychology is measured, logical, and clearly developed. It is also devastating. Buller does not seek to refute the entirety of evolutionary psychology by finding a single magic bullet. Rather, he attends to the details, finding a variety of serious problems in the different arguments that evolutionary psychologists deploy. This is philosophy of science in the trenches, and it is excellent."
