“for what is religion if not a kind of madness, and what is madness without a touch of religion?”

“There is no genius without a touch of madness.”
“No life is complete without a touch of madness.”
“No great mind has ever existed without a touch of madness.”
“It is impossible for there to be a person with no religion (i.e. without any kind of relationship to the world) as it is for there to be a person without a heart. He may not know that he has a religion, just as a person may not know that he has a heart, but it is no more possible for a person to exist without a religion than without a heart.”
