27. What is the essential of a being's nature? Form. Matter achieves (recognition) through its form; and a soul's destiny is realized by the virtue which is its form. Next we may ask whether this form be a good for a being merely because it suits its (nature)? Does desire pursue that which is suitable to it, or not? No: a being is suited by its like; now, though a being seek and love its like, its possession does not imply the possession of its good. Are we then not implying that something is suitable to a being, on the strength of its being the good of that being? The determination of what is suitable to a being belongs to the superior Being of whom the lower being is a potentiality. When a being is the potentiality of some other, the being needs the other; now the Being which it needs because it is superior is, by that very fact, its good. Of all things matter is the most indigent, and the form suitable to it is the last of all; but, above it, one may gradually ascend. Consequently, if a being be good for itself, so much the more will it consider good what is its perfection and form, namely, the being that is better than it, because of a superior nature, and of supplying the good (of the lower being). But why should that which a being receives from a superior Being be its good? Is it not this because it is eminently suited to it? No: It is so merely because it is a portion of the Good. That is why the purest and best Beings are those that have most intimacy with themselves.[124] Besides it is absurd to seek the cause why what is good, is good for itself; as if, by the mere fact of its being good, it should betray its own nature and not love itself. Nevertheless, speaking of simple beings, it might be asked whether a being which does not contain several things different from each other either possesses intimacy with itself, or can be good for itself. PLEASURE MAY ACCOMPANY THE GOOD, BUT THE GOOD IS INDEPENDENT THEREOF. Now, if all that has been said be right, it is only a gradual upward analysis that reveals the good that is suitable to the nature of any being. Desire does not constitute the good, but is born from its presence. Those who acquire the good receive something from it. Pleasure accompanies the acquirement of good; but even should pleasure not accompany the good, the good should, none the less be chosen, and sought for its own sake. MATTER IS IMPROVED BY FORM, THE DREAM OF THE GOOD.
