In fine, virtue itself, which is not among the primary objects of nature, but succeeds to them as the result of learning, though it holds the highest place among human good things, what is its occupation save to wage perpetual war with vices,--not those that are outside of us, but within; not other men's, but our own,--a war which is waged especially by that virtue which the Greeks call σωφροσύνη, and we temperance,[626] and which bridles carnal lusts, and prevents them from winning the consent of the spirit to wicked deeds? For we must not fancy that there is no vice in us, when, as the apostle says, "The flesh lusteth against the spirit;"[627] for to this vice there is a contrary virtue, when, as the same writer says, "The spirit lusteth against the flesh." "For these two," he says, "are contrary one to the other, so that you cannot do the things which you would." But what is it we wish to do when we seek to attain the supreme good, unless that the flesh should cease to lust against the spirit, and that there be no vice in us against which the spirit may lust? And as we cannot attain to this in the present life, however ardently we desire it, let us by God's help accomplish at least this, to preserve the soul from succumbing and yielding to the flesh that lusts against it, and to refuse our consent to the perpetration of sin. Far be it from us, then, to fancy that while we are still engaged in this intestine war, we have already found the happiness which we seek to reach by victory. And who is there so wise that he has no conflict at all to maintain against his vices?
