William Lane Craig is an American philosopher and Christian theologian. He holds two PHDs in philosophy and theology, and is a professor of philosophy at both Houston Baptist University and Talbot School of Theology at Biola University. Dr. Craig is arguably the world's most famous Christian apologist, and often cited as its most effective public defender. He has taken part in high-profile debates with Christopher Hitchens, Richard Dawkins, Sam Harris, and Anthony Flew, among others. Dr. Craig is the man who gave the kalam cosmological argument its name, and he speaks to Alex in this episode about that argument, and answers a number of objections to it.
