But that everything which is honourable is to be sought for its own sake, is an opinion common to us with many other schools of philosophers. For, except the three sects which exclude virtue from the chief good, this opinion must be maintained by all philosophers, and above all by us, who do not rank anything whatever among goods except what is honourable. But the defence of this opinion is very easy and simple indeed; for who is there, or who ever was there, of such violent avarice, or of such unbridled desires as not infinitely to prefer that anything which he wishes to acquire, even at the expense of any conceivable wickedness, should come into his power without crime, (even though he had a prospect of perfect impunity,) than through crime? and what utility, or what personal advantage do we hope for, when we are anxious to know whether those bodies are moving whose movements are concealed from us, and owing to what causes they revolve through the heavens? And who is there that lives according to such clownish maxims, or who has so rigorously hardened himself against the study of nature, as to be averse to things worthy of being understood, and to be indifferent to and disregard such knowledge, merely because there is no exact usefulness or pleasure likely to result from it?or, who is there who—when he comes to know the exploits, and sayings, and wise counsels of our forefathers, of the Africani, or of that ancestor of mine whom you are always talking of, and of other brave men, and citizens of pre-eminent virtue—does not feel his mind affected with pleasure? and who that has been brought up in a respectable family, and educated as becomes a freeman, is not offended with baseness as such, though it may not be likely to injure him personally? Who can keep his equanimity while looking on a man who, he thinks, lives in an impure and wicked manner? Who does not hate sordid, fickle, unstable, worthless men? But what shall we be able to say, (if we do not lay it down that baseness is to be avoided for its own sake), is the reason why men do not seek darkness and solitude, and then give the reinto every possible infamy, except that baseness of itself detects them by reason of its own intrinsic foulness? Innumerable arguments may be brought forward to support this opinion; but it is needless, for there is nothing which can be less a matter of doubt than that what is honourable ought to be sought for its own sake; and, in the same manner, what is disgraceful ought to be avoided.
But after that point is established, which we have previously mentioned, that what is honourable is the sole good; it must unavoidably be understood that that which is honourable, is to be valued more highly than those intermediate goods which we derive from it. But when we say that folly, and rashness, and injustice, and intemperance are to be avoided on account of those things which result from them, we do not speak in such a manner that our language is at all inconsistent with the position which has been laid down, that that alone is evil which is dishonourable. Because those things are not referred to any inconvenience of the body, but to dishonourable actions, which arise out of vicious propensities (vitia). For what the Greeks call κακία I prefer translating by vitium rather than by malitia.
