Go on, presbyters and synods, go on! Thrust the heretics out of the church — that is to say, throw away your brains, — put out your eyes. The infidels will thank you. They are willing to adopt your exiles. Every deserter from your camp is a recruit for the army of progress. Cling to the ignorant dogmas of the past; read the 109th Psalm; gloat over the slaughter of mothers and babes; thank God for total depravity; shower your honors upon hypocrites, and silence every minister who is touched with that heresy called genius.
Be true to your history. Turn out the astronomers, the geologists, the naturalists, the chemists, and all the honest scientists. With a whip of scorpions, drive them all out. We want them all. Keep the ignorant, the superstitious, the bigoted, and the writers of charges and specifications. Keep them, and keep them all. Repeat your pious platitudes in the drowsy ears of the faithful, and read your Bible to heretics, as kings read some forgotten riot-act to stop and stay the waves of revolution. You are too weak to excite anger. We forgive your efforts as the sun forgives a cloud — as the air forgives the breath you waste.
Robert Green Ingersoll – “Heretics and Hericies”(1874)
