To say he hath spoken to him in a Dream, is no more then to say he dreamed that God spake to him; which is not of force to win beleef from any man, that knows dreams are for the most part naturall, and may proceed from former thoughts; and such dreams as that, from selfe conceit, and foolish arrogance, and false opinion of a mans own goodlinesse, or other vertue, by which he thinks he hath merited the favour of extraordinary Revelation. To say he hath seen a Vision, or heard a Voice, is to say, that he dreamed between sleeping and waking: for in such manner a man doth many times naturally take his dream for a vision, as not having well observed his own slumbering. To say he speaks by supernaturall Inspiration, is to say he finds an ardent desire to speak, or some strong opinion of himself, for which hee can alledge no naturall and sufficient reason. So that though God Almighty can speak to a man, by Dreams, Visions, Voice, and Inspiration; yet he obliges no man to beleeve he hath so done to him that pretends it; who (being a man) may erre, and (which is more) may lie.
Thomas Hobbes
