Introduction to the Philosophy of Saint Augustine
and in whatever respect I come short, I beg you to supply my deficiencies.
5. Those who maintain that he who has one virtue has all and that he who lacks one lacks all, reason correctly from the fact that prudence cannot be cowardly, nor unjust, nor intemperate; for if it were any of these it would no longer be prudence. Moreover, if it be prudence only when it is brave, and just, and temperate, assuredly wherever it exists it must have the other virtues along with it. In like manner, also, courage cannot be imprudent, or intemperate, or unjust; temperance must of necessity be prudent, brave, and just; and justice does not exist unless it be prudent, brave, and temperate. Thus, wherever any one of these virtues truly exists, the others likewise exist; and where some are absent, that which may appear in some measure to resemble virtue is not really present.
6. There are, as you know, some vices opposed to virtués 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 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," (Matt. 10:16) and again, "to give craftiness to the simple." (Prov. 1:4) 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," using "'craftiness'' (astutia) ina 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
