But if thou art perplexed yet and dizzy at hearing this, I will ask thee nothing difficult nor involved, but a simple and plain question. Hast thou become some time bad? and hast thou become some time also good? What I mean, is like this. Didst thou prevail some time over passion, and wast thou taken again by passion? Hast thou been overtaken by drunkenness, and hast thou prevailed over drunkenness? Wast thou once moved to wrath, and again not moved to wrath? Didst thou overlook a poor man, and not overlook him? Didst thou commit whoredom once? and didst thou become chaste again? Whence then are all these things? tell me, whence? Nay if thou thyself do not tell, I will say. Because at one time thou didst restrain thyself and strive, but after that thou becamest remiss and careless. For to those that are desperate, and are continually in wickedness, and are in a state of senselessness, and are mad, and who are not willing so much as to hear what will amend them, I will not even discourse of self restraint; but to them that have been sometimes in the one, and sometimes in the other, I will gladly speak. Didst thou once take by violence the things that belonged not to thee; and after this, subdued by pity, didst impart even of thine unto him that was in need? Whence then this change? Is it not quite plain it is from the mind, and the choice of will?
