  • The Devil’s Dictionary(1911)

Richard Dawkins

On the character of God

“The God of the Old Testament is arguably the most unpleasant character in all fiction: jealous and proud of it; a petty, unjust, unforgiving control-freak; a vindictive, bloodthirsty ethnic cleanser; a misogynistic, homophobic, racist, infanticidal, genocidal, filicidal, pestilential, megalomaniacal, sadomasochistic, capriciously malevolent bully.”

On deriving ethics from scripture

“Jesus was not content to derive his ethics from the scriptures of his upbringing. He explicitly departed from them. […] Since a principal thesis of this chapter is that we do not, and should not, derive our morals from scripture; Jesus has to be honoured as a model for that very thesis.”

Albert Einstein

“It was of course a lie what you read about my religious convictions. I do not believe in a personal God and I have never denied this but have expressed it clearly. If something is in me which can be called religious then it is the inbound admiration for the structure of the world so far as our science can reveal it.”



Tantum religio potuit suadere malorum.“

“To such heights of evil are men driven by religion.”

  • De Rerum Natura (On the Nature of Things)


“All religions are equally sublime to the ignorant, useful to the politician, and ridiculous to the philosopher.”

  • De Rerum Natura (On the Nature of Things)

Friedrich Nietzsche

“There is not enough love and goodness in the world to permit giving any of it away to imaginary beings.”

Edgar Allan Poe

“All religion, my friend, is simply evolved out of fraud, fear, greed, imagination, and poetry.”

Baruch Spinoza

“I do not know how to teach philosophy, without becoming a disturber of established religion.”

Mark Twain

“Religion was invented when the first con man met the first fool.”

Sam Harris

“Faith, if it is ever right about anything, is right by accident.”


On his deathbed when asked to renounce the devil

 “This is no time to be making enemies.”

Absurdities and atrocities

“Those who can make you believe absurdities can make you commit atrocities.”

Truth of Religion

“The truths of religion are never so well understood as by those who have lost the power of reasoning.”

Steven Weinberg

“Religion is an insult to human dignity. With or without it you would have good people doing good things and bad people doing bad things. But for good people to do evil things, that takes religion.”
