“I have never made but one prayer to God, a very short one: Oh Lord, make my enemies ridiculous. And God granted it."(Letter to Étienne Noël Damilaville, May 16, 1767)”

“May God defend me from my friends: I can defend myself from my enemies. ”

“mankind have a little corrupted nature, for they were not born wolves, and they have become wolves; God has given them neither cannon of four-and-twenty pounders, nor bayonets; and yet they have made cannon and bayonets to destroy one another.”

“If God has made us in his image, we have returned him the favor.”

“Doubt is an uncomfortable condition, but certainty is a ridiculous one.”

“What can be feared when one is doing one's duty? I know the rage of my enemies. I know all their slanders; but when one only tries to do good to men and when one does not offend heaven, one can fear nothing, neither during life nor after death.”

“To pray to God is to flatter oneself that with words one can alter nature.”
