329. We can tell what a useful function is from the goal of the creation of the universe. The goal of the creation of the universe is to bring about an angelic heaven; and since an angelic heaven is the goal, so is humanity or the human race, since that is where heaven comes from. It follows, then, that everything that has been created is an intermediate goal, and that the functions are useful in the sequence, on the level, and in the specific way that they relate to humanity, and through humanity to the Lord.

363. (1) Love and wisdom, and consequently the will and intellect, constitute a person's very life. Scarcely anyone knows what life is. When anyone thinks about it, it seems as though it were something vaporous, of which no idea is possible. It seems so because people do not know that God alone is life, and that His life is Divine love and wisdom. Consequently it is apparent that nothing else is the life in a person, and that it is the life in him in the degree that he receives it.

People know that the sun radiates heat and light, of which all things in the universe are recipients, and that in the degree that they receive them they are warmed and illuminated. So it is with the sun where the Lord is, the heat radiating from it being love, and the light radiating from it being wisdom, as we showed in Part Two.

Life therefore comes from these two elements which emanate from the Lord as a sun.

[2] That love and wisdom from the Lord are life can also be seen from the fact that as love wanes in a person he becomes listless, and as wisdom fades, dull-witted; and if these were to vanish altogether, he would cease to live.

There are many properties of love which have been given other names, because they are derivations of it, such as affections, lusts, appetites, and their pleasures and delights. There are also many properties of wisdom, such as perception, reflection, recollection, cogitation, and attention to something. In addition there are many properties of both love and wisdom together, such as consent, resolve, and determination to a course of action, among others. Actually, all of these are properties of both, but they are characterized by the one that is predominant and more immediately present.

[3] Deriving finally from these two are sensations, which are those of sight, hearing, smell, taste and touch, with their delights and gratifications. The appearance is that the eye sees, but it is the intellect which sees through the eye. Consequently seeing is predicated also of the intellect. The appearance is that the ear hears, but it is the intellect which hears by means of the ear. Consequently hearing is predicated also of paying attention and listening, which is a function of the intellect. The appearance is that the nose smells, and that the tongue tastes, but it is the intellect with its perception which smells, and also tastes. Consequently smelling and tasting are predicated also of perception. And so on.

The founts of all of these phenomena are love and wisdom, from which it can be seen that these two constitute a person's life.
