There are, as you know, some vices opposed to virtues by a palpable contrast, as imprudence is the opposite of prudence. But there are some vices opposed to virtues simply because they are vices which, nevertheless, by a deceitful appearance resemble virtues; as, for example, in the relation, not of imprudence, but of craftiness to the said virtue of prudence. I speak here of that craftiness ¹ which is wont to be understood and spoken of in connection with the evilly disposed, not in the sense in which the word is usually employed in our Scriptures, where it is often used in a good sense, as, "Be crafty as serpents," ² and again, to give craftiness to the simple." ³ It is true that among heathen writers one of the most accomplished of Latin authors, speaking of Catiline, has said: "Nor was there lacking on his part craftiness to guard against danger," ⁴ using "craftiness" (astutia) in a good sense; but the use of the word in this sense is among them very rare, among us very common. So also in regard to the virtues classed under temperance. Extravagance is most manifestly opposite to the virtue of frugality; but that which the common people are wont to call niggardliness is indeed a vice, yet one which, not in its nature, but by a very deceitful similarity of appearance, usurps the name of frugality. In the same manner injustice is by a palpable contrast opposed to justice; but the desire of avenging oneself is wont often to be a counterfeit of justice, but it is a vice. There is an obvious contrariety between courage and cowardice; but hardihood, though differing from courage in nature, deceives us by its resemblance to that virtue. Firmness is a part of virtue; fickleness is a vice far removed from and undoubtedly opposed to it; but obstinacy lays claim to the name of firmness, yet is wholly different, because firmness is a virtue, and obstinacy is a vice.
