363. (i) Love and wisdom, and the will and the understanding therefrom, make the very life of man. Hardly anyone knows what life is. When one thinks about it, it seems as if it were a volatile something, of which no idea is possible. It seems so, because it is not known that God alone is Life, and that His Life is Divine Love and Wisdom; hence it is plain that in man life is nothing else, and that life is in man in the degree in which he receives this love and wisdom. It is known that light and heat go forth from the sun, and that all things in the universe are recipients, and become warm and bright in the degree in which they receive these. So also do heat and light go forth from the Sun where the Lord is; the heat going forth therefrom is Love, and the light going forth is Wisdom, as was shown in Part II. Life, therefore, comes from these two, which go forth from the Lord as the Sun. That love and wisdom from the Lord is life can be established also from this, that man grows listless as love recedes from him, and stupid as wisdom leaves him, and, if they were to recede altogether, he would be deprived of life. There are many things pertaining to love, which have had other names assigned to them because they are derivatives-as affections, desires, appetites, and their pleasures and enjoyments; and there are many things pertaining to wisdom-as perception, reflection, recollection, thought and intention towards a thing; and there are many things pertaining to both love and wisdom-as consent, conclusion and determination to action, besides others. All these, in fact, pertain to both, but are named from the more important and characteristic of the two. Finally from these two are derived sensations; they are sight, hearing, smell, taste and touch, with their enjoyments and pleasures. It is according to appearance that the eye sees, but in fact the understanding sees through the eye; on which account seeing is attributed also to the understanding. The appearance is that the ear hears, but in fact the understanding hears through the ear; therefore hearing is predicated of attention and listening which are of the understanding. The appearance is that the nose smells, and that the tongue tastes; but it is the understanding that by its perception smells and also tastes; for this reason, smelling and tasting are attributed also to perception. And so in other cases. The sources of all of these are love and wisdom; from which it can be established that these two make the life of man.
