ponder this

"Suppose there were no intelligence behind the universe.
In that case, nobody designed my brain for
the purpose of thinking.
Thought is merely a 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
