Richard Dawkins, biologist and best-selling author, claims that belief in God is a "delusion" and that "religion" harms society. Dawkins contends that he has reason and evidence on his side, and he dismisses faith as unfounded, even irrational. Dominican Thomas Crean tackles Dawkins' claims head-on. He presents straightforward arguments for God's existence, and he uses reason and evidence to defend such things as miracles and the authority of the Bible. He also shows how God is important for a coherent understanding of morality, and why Dawkins' approach winds up reducing morality to the individual's subjective likes and dislikes. By demonstrating how Dawkins' criticisms rest on misunderstandings, superficial readings, poor argumentation, a lack of historical awareness, and not a little prejudice, Crean reveals Dawkins to be out of his philosophical and theological depth, and his case against God to be fundamentally flawed.
