Baron d'Holbach

"When we examine the opinions of men, we find that nothing is more uncommon, than common sense; or, in other words, they lack judgment to discover plain truths, or to reject absurdities, and palpable contradictions."

Voltaire

"Love truth, but pardon error."

David Hume

"All sentiment is right; because sentiment has a reference to nothing beyond itself, and is always real, wherever a man is conscious of it. But all determinations of the understanding are not right; because they have a reference to something beyond themselves, to wit, real matter of fact; and are not always conformable to that standard."

Christopher Hitchens

"My own view is that this planet is used as a penal colony, lunatic asylum and dumping ground by a superior civilization, to get rid of the undesirable and unfit. I can't prove it, but you can't disprove it either. It happens to be my view, but it doesn't challenge any of the findings of Darwin or Huxley or Einstein or Hawking."
