Famed atheist Antony Flew found himself in such a position. Flew was an influential atheist and a self-identified evidentialist. He became a prominent spokesperson for atheism even as he attended C. S. Lewis’s Socratic Club, and although he respected Lewis’s work and character, he remained ambivalent to Lewis’s arguments for Christianity. Flew believed that atheism should be everyone’s default position until an evidential case for God could be made. He eventually began to question his atheism, however, as science provided him with the evidence he’d been looking for.
