Edward Feser began life as a Catholic, spent a decade as an atheist, and then returned to the fold. Why atheism didn't stick:
Speaking for myself, anyway, I can say this much. When I was an undergrad I came across the saying that learning a little philosophy leads you away from God, but learning a lot of philosophy leads you back. As a young man who had learned a little philosophy, I scoffed. But in later years and at least in my own case, I would come to see that it’s true.
