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.
