If any man pretend to me that God hath spoken to him … immediately, and I make doubt of it, I cannot easily perceive what argument he can produce to oblige me to believe it .. For to say that God … hath spoken to him in a dream is no more than to say he dreamed that God spoke to him.
Thomas Hobbes, Leviathan, Chapter 13
