C.S. Lewis on Intelligent Design

"Suppose there were no intelligence behind the universe. In that case, nobody designed my brain for the purpose of thinking. Thought is merely the by-product of some atoms within my skull. But if so, how can I trust my own thinking to be true? But if I can't trust my own thinking, of course, I can't trust the arguments leading to atheism, and therefore have no reason to be an atheist, or anything else. Unless I believe in God, I can't believe in thought; so I can never use thought to disbelieve in God." ~C.S. Lewis
