But in other arts, when anything is said to have been done according to the rules of art, there is something to be considered which is subsequent and follows upon such compliance; which they call ἐπιγεννηματικόν. But when we say in any matter that a thing has been done wisely, that same thing is from the first said also to have been done most properly; for whatever proceeds from a wise man must at once be perfect in all its parts: for in him is placed that quality which we say is to be desired. For as it is a sin to betray one’s country, to injure one’s parents, to plunder temples, which are all sins of commission; so it is likewise a sin to be afraid, to grieve, to be under the dominion of lust, even if no overt act follows these feelings. But, as these are sins, not in their later periods and consequences, but at once from the first moment; so those actions which proceed from virtue are to be considered right at the first moment that they are undertaken, and not only when they are accomplished. X. But it may be as well to give an explanation and definition of the word good, which, has been so often employed in this discourse. But the definitions of those philosophers differ a good deal from one another, and yet have all reference to the same facts. I myself agree with Diogenes, who has defined good to be that which in its nature is perfect. But that which follows, that which is profitable (for so we may translate his ὼφέλημα), he considered to be a motion, or a state, arising out of the nature of the perfect. And as the notions of things arise in the mind, if anything has become known either by practice, or by combination, or by similitude, or by the comparison of reason; then by this fourth means, which I have placed last, the knowledge of good is arrived at. For when, by a comparison of the reason, the mind ascends from those things which are according to reason, then it arrives at a notion of good. And this good we are speaking of, we both feel to be and call good, not because of any addition made to it, nor from its growth, nor from comparing it with other things, but because of its own proper power. For as honey, although it is very sweet, is still perceived to be sweet by its own peculiar kind of taste, and not by comparison with other things; so this good, which we are now treating of, is indeed to be esteemed of great value; but that valuation depends on kind and not on magnitude. For as estimation, which is called ἀξί, is not reckoned among goods, nor, on the other hand, among evils, whatever you add to it will remain in its kind. There is, therefore, another kind of estimation proper to virtue, which is of weight from its character, and not because of its increasing. Nor, indeed, are the perturbations of the mind, which make the lives of the unwise bitter and miserable, and which the Greeks call πάθη, (I might translate the word itself by the Latin _morbi_, but it would not suit all the meanings of the
