Every notion that any man, dead, living, or unborn, might form as to the universe will necessarily prove wrong

The optimist sees a light at the end of the tunnel, the realist sees a train entering the tunnel, the pessimist sees a train speeding at him, hell for leather, and the machinist sees three idiots sitting on the rail track. "The optimist proclaims that we live in the best of all possible worlds; the pessimist fears this is true."

People must have both their dreams and their dinners in this world, and when we go out of it we must take what we find. That is all.

People never want to be told anything they do not believe already.

I have followed after the truth, across this windy planet upon which every person is nourished by one or another lie.

Good and evil keep very exact accounts... and the face of every man is their ledger.

What am I that I am called upon to have prejudices concerning the universe?
