Chapter 5.—How Vicious Souls, However Worthy of Condemnation They May Be, Excel the Light Which is Praiseworthy in Its Kind.

Certainly nobody doubts that whatever is an object of intellectual perception, by virtue of divine laws surpasses in excellence every sensible object and consequently also this light.  For what, I ask, do we perceive by thought, if not that it is one thing to know with the mind, and another thing to experience bodily sensations, and that the former is incomparably more sublime than the latter, and so that intelligible things must needs be preferred to sensible things, since the intellect itself is so highly exalted above the senses?

5.  Hence this also I should perchance have known, which manifestly follows, since injustice and intemperance and other vices of the mind are not objects of sense, but of intellect, how it comes about that these too which we detest and consider condemnable, yet in as much as they are objects of intellect, can outrank this light however praiseworthy it may be in its kind.  For it is borne in upon the mind subjecting itself well to God, that, first of all, not everything that we praise is to be preferred to everything that we find fault with.  For in praising the purest lead, I do not therefore put a higher value upon it than upon the gold that I find fault with.  For everything must be considered in its kind.  I disapprove of a lawyer ignorant of many statutes, yet I so prefer him to the most approved tailor, that I should think him incomparably superior.  But I praise the tailor because he is thoroughly skilled in his own craft, while I rightly blame the lawyer because he imperfectly fulfills the functions of his profession.  Wherefore I should have found out that the light which in its own kind is perfect, is rightly to be praised; yet because it is included in the number of sensible things, which class must needs yield to the class of intelligible things, it must be ranked below unjust and intemperate souls, since these are intelligible; although we may without injustice judge these to be most worthy of condemnation.  For in the case of these we ask that they be reconciled to God, not that they be preferred to that lightning.  Wherefore, if any one had contended that this luminary is from God, I should not have opposed; but rather I should have said, that souls, even vicious ones, not in so far as they are vicious, but in so far as they are souls, must be acknowledged to be creatures of God.
