As NCSE deputy director Glenn Branch wrote in BioScience, "Kitcher discusses the evidence for, and the creationist resistance to, deep time, common ancestry, and natural selection, in vivid and fluent prose, and always with accuracy and insight. Recognizing the historical respectability and the current bankruptcy of intelligent design, he describes it as 'dead science' — although, in light of its shambling tenacity, 'zombie science' is perhaps a preferable label. Kitcher concludes by offering a historically detailed and sociologically acute diagnosis of creationism as a reaction to what is understood — and not unreasonably so, he suggests — as the vanguard of the Enlightenment's critique of supernaturalist and providentialist forms of religion."
