When I consider that I doubt, in other words that I am an incomplete and dependent being, the idea of a complete and independent being, that is to say, of God, occurs to my mind with so much clearness and distinctness,—and from the fact alone that this idea is found in me, or that I who possess it exist, the conclusions that God exists, and that my own existence, each moment of its continuance, is absolutely dependent upon him, are so manifest,—as to lead me to believe it impossible that the human mind can know anything with more clearness and certitude.
