Chapter 11.—What is
Called Evil in the Universe is But the Absence of Good.
And in the universe, even that
which is called evil, when it is regulated and put in its own
place, only enhances our admiration of the good; for we enjoy and
value the good more when we compare it with the evil. For the
Almighty God, who, as even the heathen acknowledge, has supreme
power over all things, being Himself supremely good, would never
permit the existence of anything evil among His works, if He were
not so omnipotent and good that He can bring good even out of evil.
For what is that which we call evil but the absence of good? In the
bodies of animals, disease and wounds mean nothing but the absence
of health; for when a cure is effected, that does not mean that the
evils which were present—namely, the diseases and wounds—go
away from the body and dwell elsewhere: they altogether cease to
exist; for the wound or disease is not a substance, but a defect in
the fleshly substance,—the flesh itself being a substance, and
therefore something good, of which those evils—that is,
privations of the good which we call health—are accidents. Just
in the same way, what are called vices in the soul are nothing but
privations of natural good. And when they are cured, they are not
transferred elsewhere: when they cease to exist in the healthy
soul, they cannot exist anywhere else.
