In his latest book, Ruse uncovers surprising similarities between evolutionist and creationist thinking. Exploring the underlying philosophical commitments of evolutionists, he reveals that those most hostile to religion are just as evangelical as their fundamentalist opponents. But more crucially, and reaching beyond the biblical issues at stake, he demonstrates that these two diametrically opposed ideologies have, since the Enlightenment, engaged in a struggle for the privilege of defining human origins, moral values, and the nature of reality.
