Bertrand Russell

"Most of the greatest evils that man has inflicted upon man have come through people feeling quite certain about something which, in fact, was false."

Robert Green Ingersoll

"I admit that reason is a small and feeble flame, a flickering torch by stumblers carried in the star-less night, -- blown and flared by passion's storm, -- and yet, it is the only light. Extinguish that, and nought remains."

Sam Harris

"The president of the United States has claimed, on more than one occasion, to be in dialogue with God. If he said that he was talking to God through his hairdryer, this would precipitate a national emergency. I fail to see how the addition of a hairdryer makes the claim more ridiculous or offensive."

Mark Twain

"Often, the less there is to justify a traditional custom, the harder it is to get rid of it."
