It is after all the unifying question all Humans have pondered for possibly hundreds of thousands of years now. We still have no answers, maybe that's why we have religion? In any case, humans can't answer this fundamental question no matter how good our science has gotten so in my book, he's okay to give up on that. Life is too short. If theism works for someone, especially after such a great effort to find answers, he sounds like an ideal human to me. Probably a really level headed individual, but I'm just guessing like everybody else.
