Knowledge

“You deal with the madmen. All men are mad in some way or the other; and inasmuch as you deal discreetly with your madmen, so deal with God’s madmen, too—the rest of the world. You tell not your madmen what you do nor why you do it; you tell them not what you think. So you shall keep knowledge in its place, where it may rest—where it may gather its kind around it and breed.”

Bram Stoker, Dracula (Prof. Abraham Van Helsing)
