Let no one marvel if I speak what seems difficult to understand; for to myself it seems a miracle how it is possible even to arrive at a conclusion concerning it, and to perceive it with the intellect. It is not a thing to reveal in language, especially the language of the Vulgar Tongue; wherefore I will say, even as did the Apostle: "Oh, great is the depth of the riches of Wisdom of God: how incomprehensible are Thy judgments, and Thy ways past finding out!" And since the complex nature of the seed may be better and less good, and the disposition of the receiver of the seed may be better and less good, and the disposition of the dominant Heaven to this effect may be good and better and best, which varies in the constellations, which are continually transformed; it befalls that from the human seed and from these virtues or powers the Soul is produced more or less pure; and according to its purity there descends into it the virtue or power of the possible or passive intellect, as it is called, and as it has been spoken of. And if it happen that through the purity of the receptive Soul the intellectual power is indeed separate and absolute, free from all corporeal shadow, the Divine Goodness multiplies in it, as in a thing sufficient to receive that good gift; and then it multiplies in the Soul of this intelligent being, according as it can receive it; and this is that seed of Happiness of which we speak at present. And this is in harmony with the opinion of Tullius in that book on Old Age when, speaking personally of Cato, he says: "For this reason a celestial spirit descended into us from the highest habitation, having come into a place which is adverse to the Divine Nature and to Eternity." And in such a Soul as this there is its own individual power, and the intellectual power, and the Divine power; that is to say, that influence which has been mentioned. Therefore it is written in the book On Causes: "Each Noble Soul has three operations, that is to say, the animal, the intellectual, and the Divine." And there are some men who hold such opinions that they say, if all the preceding powers were to unite in the production of a Soul in their best disposition, arrangement, order, that into that Soul would descend so much of the Deity that it would be as it were another God Incarnate; and this is almost all that it is possible to say concerning the Natural way.
