From the publisher: "Philip Kitcher is one of the leading figures in the philosophy of science today. Here he collects, for the first time, many of his published articles on the philosophy of biology, spanning from the mid-1980s to the present. ... Kitcher's articles cover a broad range of topics with similar philosophical and social significance: sociobiology, evolutionary psychology, species, race, altruism, genetic determinism, and the rebirth of creationism in Intelligent Design. Kitcher's work on the intersection of biology and the philosophy of science is both unprecedented and wide-ranging, and will appeal not only to philosophers of science, but to scholars and students across disciplines."
