Chapter XVI.—Because Some are Wise, Nothing Prevents Others from Being So; Virtue is to Be Acquired by Diligence and Study; By a Sounder Philosophy Men are to Be Carried Onwards to the Good; The Common Study of Virtue Has by Christ Been Opened Up to All. In general, it is worth while to inquire of these men, “Is it possible for no man to become good, or is it in the power of any one?” For if no man is wise, what of Manichæus himself? I pass over the fact that he not only calls others good, but he also says that they are able to make others such. But if one individual is entirely good, what prevents all from becoming good? For what is possible for one is possible also for all. And by the means by which one has become virtuous, by the same all may become so, unless they assert that the larger share of this virtue is intercepted by such. Again, therefore, first, What necessity is there for labour in submitting to discipline (for even whilst sleeping we may become virtuous), or what cause is there for these men rousing their hearers to hopes of good? For even though wallowing in the mire with harlots, they can obtain their proper good. But if discipline, and better instruction and diligence in acquiring virtue, make a man to become virtuous, let all become so, and that oft-repeated phrase of theirs, the unordered motion of matter, is made void. But it would be much better for them to say that wisdom is an instrument given by God to man, in order that by bringing round by degrees to good that which arises to them, from the fact of their being endowed with sense, out of desire or pleasure, it might remove from them the absurdities that flow from them. For thus they themselves who profess to be teachers of virtue would be objects of emulation for their purpose, and for their mode of life, and there would be great hopes that one day evils will cease, when all men have become wise. And this it seems to me that Jesus took into consideration; and in order that husbandmen, carpenters, builders, and other artisans, might not be driven away from good, He convened a common council of them altogether, and by simple and easy conversations He both raised them to a sense of God, and brought them to desire what was good.
