22. Let them perish from thy presence, O God, as vain talkers, and deceivers of the soul perish, who, when they observe that there are two wills in the act of deliberation, go on to affirm that there are two kinds of minds in us: one good, the other evil. They are indeed themselves evil when they hold these evil opinions--and they shall become good only when they come to hold the truth and consent to the truth that thy apostle may say to them: "You were formerly in darkness, but now are you in the light in the Lord." But they desired to be light, not "in the Lord," but in themselves. They conceived the nature of the soul to be the same as what God is, and thus have become a thicker darkness than they were; for in their dread arrogance they have gone farther away from thee, from thee "the true Light, that lights every man that comes into the world." Mark what you say and blush for shame; draw near to him and be enlightened, and your faces shall not be ashamed.
While I was deliberating whether I would serve the Lord my God now, as I had long purposed to do, it was I who willed and it was also I who was unwilling. In either case, it was I. I neither willed with my whole will nor was I wholly unwilling. And so I was at war with myself and torn apart by myself. And this strife was against my will; yet it did not show the presence of another mind, but the punishment of my own. Thus it was no more I who did it, but the sin that dwelt in me--the punishment of a sin freely committed by Adam, and I was a son of Adam.
23. For if there are as many opposing natures as there are opposing wills, there will not be two but many more. If any man is trying to decide whether he should go to their conventicle or to the theater, the Manicheans at once cry out, "See, here are two natures--one good, drawing this way, another bad, drawing back that way; for how else can you explain this indecision between conflicting wills?" But I reply that both impulses are bad--that which draws to them and that which draws back to the theater. But they do not believe that the will which draws to them can be anything but good. Suppose, then, that one of us should try to decide, and through the conflict of his two wills should waver whether he should go to the theater or to our Church. Would not those also waver about the answer here? For either they must confess, which they are unwilling to do, that the will that leads to our church is as good as that which carries their own adherents and those captivated by their mysteries; or else they must imagine that there are two evil natures and two evil minds in one man, both at war with each other, and then it will not be true what they say, that there is one good and another bad. Else they must be converted to the truth, and no longer deny that when anyone deliberates there is one soul fluctuating between conflicting wills.
24. Let them no longer maintain that when they perceive two wills to be contending with each other in the same man the contest is between two opposing minds, of two opposing substances, from two opposing principles, the one good and the other bad. Thus, O true God, thou dost reprove and confute and convict them. For both wills may be bad: as when a man tries to decide whether he should kill a man by poison or by the sword; whether he should take possession of this field or that one belonging to someone else, when he cannot get both; whether he should squander his money to buy pleasure or hold onto his money through the motive of covetousness; whether he should go to the circus or to the theater, if both are open on the same day; or, whether he should take a third course, open at the same time, and rob another man's house; or, a fourth option, whether he should commit adultery, if he has the opportunity--all these things concurring in the same space of time and all being equally longed for, although impossible to do at one time. For the mind is pulled four ways by four antagonistic wills--or even more, in view of the vast range of human desires--but even the Manicheans do not affirm that there are these many different substances. The same principle applies as in the action of good wills. For I ask them, "Is it a good thing to have delight in reading the apostle, or is it a good thing to delight in a sober psalm, or is it a good thing to discourse on the gospel?" To each of these, they will answer, "It is good." But what, then, if all delight us equally and all at the same time? Do not different wills distract the mind when a man is trying to decide what he should choose? Yet they are all good, and are at variance with each other until one is chosen. When this is done the whole united will may go forward on a single track instead of remaining as it was before, divided in many ways. So also, when eternity attracts us from above, and the pleasure of earthly delight pulls us down from below, the soul does not will either the one or the other with all its force, but still it is the same soul that does not will this or that with a united will, and is therefore pulled apart with grievous perplexities, because for truth's sake it prefers this, but for custom's sake it does not lay that aside.
