From Aquinas to Leibniz to Pruss and Rasmussen, cosmological arguments have a long and formidable pedigree. I this video, I analyze twenty such arguments for God's existence. NOTE (ADDED 3/21/26): This video represented my views at the time of recording. Some of my views have changed since then, but I'm leaving the video up because it contains lots of helpful information, and also shows my thinking at the time. Like the show? Help it grow!
