Commenting on the first edition of Sober's book, David L. Hull wrote, "Elliott Sober has written Philosophy of Biology as an introductory text, and as such it succeeds admirably. But in addition to addressing more popular controversies such as sociobiology and creationism, he also motivates, elucidates, and even advances the current debates among his peers. As always, Sober's exposition is clear and penetrating." The second edition (2000) brings the text up to date. Sober is Hans Reichenbach Professor of Philosophy at the University of Wisconsin at Madison and the editor of Conceptual Issues in Evolutionary Biology (now in its third edition).
