15. Those who claim that matter does not exist, will have to be referred to our extended discussion[196] where we have demonstrated the necessity of its hypostatic existence. Those who would assert that evil does not belong among beings would, if logical, thereby also deny the existence of the good, and of anything that was desirable; thereby annihilating desire, as well as aversion, and even thought; for everybody shares desire for the good, and aversion for the evil. Thought and knowledge, simultaneously, apply to good and evil; thought itself is a good. EXPLANATION OF THE EVIL OF THE SOUL. We must, therefore, acknowledge the existence first of Good, unmixed, and then the nature mingled of good and evil; but what most participates in evil thereby trends towards absolute Evil; and what participates in it to a less degree thereby trends towards good. For what is evil to soul? It is being in contact with inferior nature; otherwise the soul would not have any appetite, pain, or fear. Indeed fear is felt by us only for the composite (of soul and body), fearing its dissolution, which thus is the cause of our pains and sufferings. The end of every appetite is to put aside what troubles it, or to forestall what might do so. As to sense-representations (fancy[197]), it is the impression made by an exterior object on the irrational part of the soul, a part which can receive this impression only because it is not indivisible. False opinion rises within the soul because it is no longer within truth, and this occurs because the soul is no longer pure. On the contrary, the desire of the intelligible leads the soul to unite intimately with intelligence, as she should, and there remain solidly entrenched, without declining towards anything inferior. It is only because of the nature and power of the Good that evil does not remain pure Evil. (Matter, which is synonymous with evil) is like a captive which beauty covers with golden chains, so that the divinities might not see its nakedness, and that men might not be intruded on by it; or that men, if they must see it, shall be reminded of beauty on observing an even weakened image thereof. SECOND ENNEAD, BOOK THREE. Whether Astrology is of any Value.[198] OF THE INFLUENCE OF THE STARS. 1. It has been said[199] that the course of the stars indicates what is to happen to each being; though, it does not, as many persons think, cause every event. To the supporting proofs hereof we are to add now more precise demonstrations, and new considerations, for the opinion held about this matter is no trifle. VARIOUS PRETENSIONS OF ASTROLOGY.
