XXXIV. (188) Such then are the fountains of intermediate instruction. Let us now consider the fountain of folly, concerning which the lawgiver speaks thus, "Whosoever shall lie with a woman who is sitting apart has uncovered her fountain, and she has uncovered the issue of blood; they shall both be Destroyed."[Le 20:18.] Here he calls the external sense a woman, representing the mind as her husband. (189) When therefore the woman, having forsaken her legitimate husband, settles near those objects of the external sense which allures and destroys, and embraces them all in this amorous manner; then therefore, if the mind be turned to sleep when it is necessary that it should be awakened, it has uncovered the fountain of the external sense, that is itself, that is to say, it has rendered itself, without a covering and without a wall, and easy to be plotted against. (190) But nevertheless the woman also has uncovered the fountain of her blood, for every external sense, when flowing towards the external object appreciable by it, is cheered and restrained by being under the dominion of the reason; and it is left in a solitary condition, being deprived of any proper governor. And as the most terrible misfortune for a city is to be without walls, so the most unfortunate state for a soul is to be without a guardian. (191) When, then, is it without a guardian? Is it not when the sight is without any covering, being poured forth upon the objects of sight; and when the hearing is without a covering, being occupied in drinking in all kinds of sounds; and when the sense of smell is uncovered, and the kindred powers are left to themselves, and so are most ready to suffer whatever the invading enemy may be disposed to inflict? And that speech is uncovered and uttered which speaks ten thousand things in an unseasonable manner, without any thing to restrain its impetuosity; therefore flowing on unrestrainedly, it overturns many noble purposes and plans of life which were previously sailing on erect as though in calm weather. (192) This is that great deluge in which "the cataracts of heaven were opened"58--by heaven I here mean the mind--and the fountains of the bottomless pit were revealed; that is to say, of the outward sense; for in this way alone is the soul overwhelmed, iniquities being broken up and poured over it from above, as from the heaven of the mind, and the passions irrigating it from below, as from the earth of the outward senses. (193) For which reason Moses forbids a man to uncover the nakedness of his father or of his mother, [Le 18:7.] well knowing how great an evil it is not to check and to conceal the offences of the mind and of the external senses, but to bring them forward and display them as though they were good actions.
