211. II. WITH THOSE WHO ARE IN LOVE TRULY CONJUGIAL, THE FACULTY OF GROWING WISE INCREASES; BUT WITH THOSE WHO ARE NOT IT DECREASES. The faculty of growing wise increases with those who are in love truly conjugial, because this love appertains to married partners on account of wisdom, and according to it, as has been fully proved in the preceding sections; also, because the sense of that love is the touch, which is common to all the senses, and also is full of delights; in consequence of which it opens the interiors of the mind, as it opens the interiors of the senses, and therewith the organical principles of the whole body. Hence it follows, that those who are principled in that love, prefer nothing to growing wise; for a man grows wise in proportion as the interiors of his mind are opened; because by such opening, the thoughts of the understanding are elevated into superior light, and the affections of the will into superior heat; and superior light is wisdom, and superior heat is the love thereof. Spiritual delights conjoined to natural delights, which are the portion of those who are in love truly conjugial, constitute loveliness, and thence the faculty of growing wise. Hence it is that the angels have conjugial love according to wisdom; and the increase of that love and at the same time of its delights is according to the increase of wisdom; and spiritual offspring, which are produced from their marriages, are such things as are of wisdom from the father, and of love from the mother, which they love from a spiritual _storge_; which love unites with their conjugial love, and continually elevates it, and joins them together. 212. The contrary happens with those who are not in any conjugial love, from not having any love of wisdom. These enter the marriage state with no other end in view than lasciviousness, in which is also the love of growing insane; for every end considered in itself is a love, and lasciviousness in its spiritual origin is insanity. By insanity we mean a delirium in the mind occasioned by false principles; and an eminent degree of delirium is occasioned by truths which are falsified until they are believed to be wisdom. That such persons are opposed to conjugial love, is confirmed or evinced by manifest proof in the spiritual world; where, on perceiving the first scent of conjugial love, they fly into caverns, and shut the doors; and if these are opened, they rave like madmen in the world.
