The pursuit of truth is like an onion. You peel away one layer and you become reasonably certain you know the answer. This is where most people stop. But if you want to be really certain; you peel away another layer and suddenly you discover facts that draw into question the assumptions you made earlier. Now, you have many more questions and you're far less certain. So, you peel away another layer and there you discover a mind-boggling array of contradictions. You become confused and frightened. Your choice is stark at this point: you either surrender to the comfort of God, the Almighty.... or you peel away another layer and go mad.
