Robert G. Ingersoll, The Ghosts and Other Lectures

"Take from the church the miraculous, the supernatural, the incomprehensible, the unreasonable, the impossible, the unknowable, the absurd, and nothing but a vacuum remains."

"I will not attack your doctrines nor your creeds if they accord liberty to me. If they hold thought to be dangerous - if they aver that doubt is a crime, then I attack them one and all, because they enslave the minds of men. I attack the monsters, the phantoms of imagination that have ruled the world. I attack slavery. I ask for room -- room for the human mind."

"Nothing but truth is immortal."
