William Lane Craig and Walter Sinnott-Armstrong, God? A Debate between a Christian and an Atheist. Craig is the Christian with two earned doctorates, one on Cosmology, the theory of origins. I would like to say this is an easy read, and though in places it is, one has to concentrate hard to keep up with the arguments pro and con. One weakness is that Craig does not challenge the origin of reason or origin of logic and allows Sinnott-Armstrong to pretend the autonomy of human thought.
