6. Let us examine the significance of the doctrine[174] that evils cannot be destroyed, that they are necessary, that they do not exist among the divinities, but that they ever besiege our mortal nature, and the place in which we dwell.[175] Surely heaven is free from all evil because it moves eternally with regularity, in perfect order; because in the stars is neither injustice nor any other kind of evil, because they do not conflict with each other in their courses; and because their revolutions are presided over by the most beautiful harmony.[164] On the contrary, the earth reveals injustice and disorder, (chiefly) because our nature is mortal, and we dwell in a lower place. But when Plato,[176] says, that we must flee from here below, he does not mean that we should leave the earth, but, while remaining therein, practice justice, piety, and wisdom. It is wickedness that must be fled from, because wickedness and its consequences are the evil of man. EVIL IS NOT GOOD'S QUALITATIVE, BUT ONLY FIGURATIVE ANTAGONIST. When[176] (Theodor) tells (Socrates) that evils would be annihilated if men practised (Socrates') teachings, the latter answers that that is impossible, for evil is necessary even if only as the contrary of good. But how then can wickedness, which is the evil of man, be the contrary of good? Because it is the contrary of virtue. Now virtue, without being Good in itself, is still a good, a good which makes us dominate matter. But how can Good in itself, which is not a quality, have a contrary? Besides, why need the existence of one thing imply its contrary? Though we may grant that there is a possibility of the existence of the contrary of some things--as for instance, that a man in good health might become sick--there is no such necessity. Nor does Plato assert that the existence of each thing of this kind necessarily implies that of its contrary; he makes this statement exclusively of the Good. But how can there be a contrary to good, if the good be "being," let alone "above being"?[177] Evidently, in reference to particular beings, there can be nothing contrary to "being." This is proved by induction; but the proposition has not been demonstrated as regards universal Being. What then is the contrary of universal Being, and first principles in general? The contrary of "being" must be nonentity; the contrary of the nature of the Good is the nature and principle of Evil. These two natures are indeed respectively the principles of goods and of evils. All their elements are mutually opposed, so that both these natures, considered in their totality, are still more opposed than the other contraries. The latter, indeed, belong to the same form, to the same kind, and they have something in common in whatever subjects they may be. As to the Contraries that are essentially distinguished from each other, whose nature is constituted of elements opposed to the constitutive elements of the other, those
