“This must be our belief when we have a correct knowledge of our own self, and comprehend the true nature of everything; we must be content, and not trouble our mind with seeking a certain final cause for things that have none, or have no other final cause but their own existence, which depends on the Will of God, or, if you prefer, on the Divine Wisdom.”

1790s, Discourse to the Theophilanthropists (1798)
Context: The universe is the bible of a true Theophilanthropist. It is there that he reads of God. It is there that the proofs of his existence are to be sought and to be found. As to written or printed books, by whatever name they are called, they are the works of man's hands, and carry no evidence in themselves that God is the author of any of them. It must be in something that man could not make, that we must seek evidence for our belief, and that something is the universe; the true bible; the inimitable word, of God.
