Nicomachean Ethics

Next comes the question, whether a man is a man of Self-Control for abiding by his conclusions and moral choice be they of what kind they may, or only by the right one; or again, a man of Imperfect Self-Control for not abiding by his conclusions and moral choice be they of whatever kind; or, to put the case we did before, is he such for not abiding by false conclusions and wrong moral choice?

Is not this the truth, that it is by conclusions and moral choice of any kind that the one character abides and the other does not, but true conclusions and right moral choice:[19] to explain what is meant by incidentally, and ; suppose a man chooses or pursues this thing for the sake of that, he is said to pursue and choose that , but this only incidentally. For the term we use commonly the word “simply,” and so, in a way, it is opinion of any kind soever by which the two characters respectively abide or not, but he is “simply” entitled to the designations who abides or not by the true opinion.

There are also people, who have a trick of abiding by their, own opinions, who are commonly called Positive, as they who are hard to be persuaded, and whose convictions are not easily changed: now these people bear some resemblance to the character of Self-Control, just as the prodigal to the liberal or the rash man to the brave, but they are different in many points. The man of Self-Control does not change by reason of passion and lust, yet when occasion so requires he will be easy of persuasion: but the Positive man changes not at the call of Reason, though many of this class take up certain desires and are led by their pleasures. Among the class of Positive are the Opinionated, the Ignorant, and the Bearish: the first, from the motives of pleasure and pain: I mean, they have the pleasurable feeling of a kind of victory in not having their convictions changed, and they are pained when their decrees, so to speak, are reversed: so that, in fact, they rather resemble the man of Imperfect Self-Control than the man of Self-Control.

Again, there are some who depart from their resolutions not by reason of any Imperfection of Self-Control; take, for instance, Neoptolemus in the Philoctetes of Sophocles. Here certainly pleasure was the motive of his departure from his resolution, but then it was one of a noble sort: for to be truthful was noble in his eyes and he had been persuaded by Ulysses to lie.

So it is not every one who acts from the motive of pleasure who is utterly destitute of Self-Control or base or of Imperfect Self-Control, only he who acts from the impulse of a base pleasure.
