276. Those who believe that a knowledge of God, of heaven and hell, and of the spiritual things pertaining to the church, can be gained from their own intelligence, do not know that a natural man, viewed in himself, is opposed to the spiritual, and therefore desires to extirpate the spiritual things that enter, or to involve them in fallacies, which are like the worms that consume the roots of herbs and grain. Such may be likened to men who dream that they are seated upon eagles and are borne up on high, or are mounted on Pegasus and are flying over Mount Parnassus to Helicon; while actually they are like the Lucifers in hell, who still call themselves there "sons of the morning" (Isa. 14:12). They are also like the men in the valley of the land of Shinar, who attempted to build a tower, the head of which should reach to heaven (Gen. 11:2-4); and like Goliath they trust to themselves, not foreseeing that like him they might be prostrated by a sling-stone buried in the forehead. I will tell what lot awaits such after death. At first they become as if drunk, then like fools, and at last they become stupid and dwell in darkness. Therefore let men beware of such madness.
