“Religions die when they are proved to be true. Science is the record of dead religions.”

“Truth, in matters of religion, is simply the opinion that has survived.”

“Even things that are true can be proved.”

“The terror of society, which is the basis of morals, the terror of God, which is the secret of religion-these are the two things that govern us.”

“What of Art?-It is a malady.--Love?-An Illusion.--Religion?-The fashionable substitute for Belief.--You are a sceptic.-Never! Scepticism is the beginning of Faith.--What are you?-To define is to limit.”

“A thing is not necessarily true because a man dies for it.”

“Just because a man has died for it, does not make it true.”
