Is Faith in God Reasonable? — William Lane Craig vs. Alex Rosenberg

Topic: Whether religious belief can be rationally justified in light of a naturalistic worldview

Debaters: Dr. William Lane Craig vs. Dr. Alex Rosenberg (philosopher of science, Duke University)

Recorded at Purdue University in 2013, this debate is notable because Rosenberg is an unusually consistent naturalist: he argues that if atheism is true, there is no libertarian free will, no objective purpose, no enduring self, and no real moral facts. Craig's strategy was to use Rosenberg's own consistency against him, arguing that a worldview which cannot ground reason, morality, or personal identity undercuts its own claim to be believed. One of the best debates for showing that atheism carries philosophical costs its casual defenders rarely spell out.
