This is a pretty good, albeit somewhat introductory, book on the major theistic proofs. Covering the Ontological, Cosmological, and Teleological Arguments in Davis’ chosen formulation, each is presented and defended from objections. Along the way Davis discusses religious realism vs. non-realism, reformed epistemology, and a few other topics related to theistic proofs.
The writing is clear and engaging, and the arguments are well defended. Of course not every single possible objection can be met in a short book such as this, but I felt reasonably happy that any of my own personal objections to the major arguments had been met. I also emailed Davis with a question about the Ontological Argument and he responded, which is always appreciated! As of today this is probably the book I would recommend to someone showing interest in arguments for God’s existence.
