23. For if there be as many contrary natures as there are conflicting wills, there will not now be two natures only, but many. If any one deliberate whether he should go to their conventicle, or to the theatre, those men at once cry out, Behold, here are two natures—one good, drawing this way, another bad, drawing back that way; for whence else is this indecision between conflicting wills? But I reply that both are bad— that which draws to them, and that which draws back to the theatre. But they believe not that will to be other than good which draws to them. Supposing, then, one of us should deliberate, and through the conflict of his two wills should waver whether he should go to the theatre or to our church, would not these also waver what to answer? For either they must confess, which they are not willing to do, that the will which leads to our church is good, as well as that of those who have received and are held by the mysteries of theirs, or they must imagine that there are two evil natures and two evil minds in one man, at war one with the other; and that will not be true which they say, that there is one good and another bad; or they must be converted to the truth, and no longer deny that where any one deliberates, there is one soul fluctuating between conflicting wills.
