John Locke on Revelation and Reason
An Essay Concerning Human Understanding, ed. Alexander Fraser (New York: Dover, 1959; orig. 1689), IV, xix, 14, p. 439.I do not mean that we must consult reason, and examine whether a proposition revealed from God can be made out by natural principles, and if it cannot, that then we may reject it: but consult it we must, and by it examine whether it be a revelation from God or no: and if reason finds it to be revealed from God, reason then declares for it as much as for any other truth, and makes it one of her dictates.
