403. (5) Love or the will prepares all things in its own human form, that it may act conjointly with wisdom or the understanding. We say, will and understanding, but it is to be carefully borne in mind that the will is the entire man; for it is the will that, with the understanding, is in first principles in the brains, and in derivatives in the body, consequently in the whole and in every part (see above, n. 365-367). From this it can be seen that the will is the entire man as regards his very form, both the general form and the particular form of all parts; and that the understanding is its partner, as the lungs are the partner of the heart. Beware of cherishing an idea of the will as something separate from the human form, for it is that same form. From this it can be seen not only how the will prepares a bridal chamber for the understanding, but also how it prepares all things in its house (which is the whole body) that it may act conjointly with the understanding. This it prepares in such a way that as each and every thing of the body is conjoined to the will, so is it conjoined to the understanding; in other words, that as each and everything of the body is submissive to the will, so is it submissive to the understanding. How each and every thing of the body is prepared for conjunction with the understanding as well as with the will, can be seen in the body only as in a mirror or image, by the aid of anatomical knowledge, which shows how all things in the body are so connected, that when the lungs respire each and every thing in the entire body is moved by the respiration of the lungs, and at the same time from the beating of the heart. Anatomy shows that the heart is joined to the lungs through the auricles, which are continued into the interiors of the lungs; also that all the viscera of the entire body are joined through ligaments to the chamber of the breast; and so joined that when the lungs respire, each and all things, in general and in particular, partake of the respiratory motion. Thus when the lungs are inflated, the ribs expand the thorax, the pleura is dilated, and the diaphragm is stretched wide, and with these all the lower parts of the body, which are connected with them by ligaments therefrom, receive some action through the pulmonic action; not to mention further facts, lest those who have no knowledge of anatomy, on account of their ignorance of its terms should be confused in regard to the subject. Consult any skillful and discerning anatomist whether all things in the entire body, from the breast down be not so bound together, that when the lungs expand by respiration, each and all of them are moved to action synchronous with the pulmonic action. From all this the nature of the conjunction prepared by the will between the understanding and each and every thing of the human form is now evident. Only explore the connections well and scan them with an anatomical eye; then, following the connections, consider their cooperation with the breathing lungs and with the heart; and finally, in thought, substitute for the lungs the understanding, and for the heart the will, and you will see.
