You can know nothing of God, of nature, of heaven, or hell, or yourself, but so far as all these things are self-evident in you. Neither could any of these things be of any concern to you, but because they can all of them be self-evident in you. For the bare history, or hearsay of any one thing, signifies no more to you, than the hearsay of any other thing. And if God and heaven, hell and the devil, the world and the flesh, were not all of them self-evident in you, you could have no more good or hurt from any hearsay about them, than from the hearsay of pleasant gardens, and dismal prisons, in the world of the moon.
