pleasures and pains, and that it is either increased or marred by the same circumstances (differently used) by which it is originally generated, and that it exerts itself on the same circumstances out of which it was generated.
Now I can conceive a person perplexed as to the meaning of our statement, that men must do just actions to become just, and those of self-mastery to acquire the habit of self-mastery; "for," he would say, "if men are doing the actions they have the respective virtues already, just as men are grammarians or musicians when they do the actions of either art." May we not reply by saying that it is not so even in the case of the arts referred to: because a man may produce something grammatical either by chance or the suggestion of another; but then only will he be a grammarian when he not only produces something grammatical but does so grammarian-wise, i.e. in virtue of the grammatical knowledge he himself possesses.
Again, the cases of the arts and the virtues are not parallel: because those things which are produced by the arts have their excellence in themselves, and it is sufficient therefore [Sidenote: 1105b] that these when produced should be in a certain state: but those which are produced in the way of the virtues, are, strictly speaking, actions of a certain kind (say of Justice or perfected Self-Mastery), not merely if in themselves they are in a certain state but if also he who does them does them being himself in a certain state, first if knowing what he is doing, next if with deliberate preference, and with such preference for the things' own sake; and thirdly if being himself stable and unapt to change. Now to constitute possession of the arts these requisites are not reckoned in, excepting the one point of knowledge: whereas for possession of the virtues knowledge avails little or nothing, but the other requisites avail not a little, but, in fact, are all in all, and these requisites as a matter of fact do come from oftentimes doing the actions of Justice and perfected Self-Mastery.
The facts, it is true, are called by the names of these habits when they are such as the just or perfectly self-mastering man would do; but he is not in possession of the virtues who merely does these facts, but he who also so does them as the just and self-mastering do them.
We are right then in saying, that these virtues are formed in a man by his doing the actions; but no one, if he should leave them undone, would be even in the way to become a good man. Yet people in general do not perform these actions, but taking refuge in talk they flatter themselves they are philosophising, and that they will so be good men: acting in truth very like those sick people who listen to the doctor with great attention but do nothing that he tells them: just as these then cannot be well bodily under such a course of treatment, so neither can those be mentally by such philosophising.
[Sidenote: V] Next, we must examine what Virtue is. Well, since the things which come to be in the mind are, in all, of three kinds, Feelings, Capacities, States, Virtue of course must belong to one of the three classes.
By Feelings, I mean such as lust, anger, fear, confidence, envy, joy, friendship, hatred, longing, emulation, compassion, in short all such as are followed by pleasure or pain: by Capacities, those in right of which we are said to be capable of these feelings; as by virtue of which we are able to have been made angry, or grieved, or to have compassionated; by States, those in right of which we are in a certain relation good or bad to the aforementioned feelings; to having been made angry, for instance, we are in a wrong relation if in our anger we were too violent or too slack, but if we were in the happy medium we are in a right relation to the feeling. And so on of the rest.
Now Feelings neither the virtues nor vices are, because in right of the Feelings we are not denominated either good or bad, but in right of the virtues and vices we are.
[Sidenote: 1106_a_] Again, in right of the Feelings we are neither praised nor blamed (for a man is not commended for being afraid or being angry, nor blamed for being angry merely but for being so in a particular way), but in right of the virtues and vices we are.
Again, both anger and fear we feel without moral choice, whereas the virtues are acts of moral choice, or at least certainly not independent of it.
Moreover, in right of the Feelings we are said to be moved, but in right of the virtues and vices not to be moved, but disposed, in a certain way.
And for these same reasons they are not Capacities, for we are not called good or bad merely because we are able to feel, nor are we praised or blamed.
And again, Capacities we have by nature, but we do not come to be good or bad by nature, as we have said before.
Since then the virtues are neither Feelings nor Capacities, it remains that they must be States.
[Sidenote: VI] Now what the genus of Virtue is has been said; but we must not merely speak of it thus, that it is a state but say also what kind of a state it is. We must observe then that all excellence makes that whereof it is the excellence both to be itself in a good state and to perform its work well. The excellence of the eye, for instance, makes both the eye good and its work also: for by the excellence of the eye we see well. So too the excellence of the horse makes a horse good, and good in speed, and in carrying his rider, and standing up against the enemy. If then this is universally the case, the excellence of Man, i.e. Virtue, must be a state whereby Man comes to be good and whereby he will perform well his proper work. Now how this shall be it is true we have said already, but still perhaps it may throw light on the subject to see what is its characteristic nature.
In all quantity then, whether continuous or discrete, one may take the greater part, the less, or the exactly equal, and these either with reference to the thing itself, or relatively to us: and the exactly equal is a mean between excess and defect. Now by the mean of the thing, i.e. absolute mean, I denote that which is equidistant from either extreme (which of course is one and the same to all), and by the mean relatively to ourselves, that which is neither too much nor too little for the particular individual. This of course is not one nor the same to all: for instance, suppose ten is too much and two too little, people take six for the absolute mean; because it exceeds the smaller sum by exactly as much as it is itself exceeded by the larger, and this mean is according to arithmetical proportion.
[Sidenote: 1106_b_] But the mean relatively to ourselves must not be so found ; for it does not follow, supposing ten minæ is too large a quantity to eat and two too small, that the trainer will order his man six; because for the person who is to take it this also may be too much or too little: for Milo it would be too little, but for a man just commencing his athletic exercises too much: similarly too of the exercises themselves, as running or wrestling.
So then it seems every one possessed of skill avoids excess and defect, but seeks for and chooses the mean, not the absolute but the relative.
Now if all skill thus accomplishes well its work by keeping an eye on the mean, and bringing the works to this point (whence it is common enough to say of such works as are in a good state, "one cannot add to or take ought from them," under the notion of excess or defect destroying goodness but the mean state preserving it), and good artisans, as we say, work with their eye on this, and excellence, like nature, is more exact and better than any art in the world, it must have an aptitude to aim at the mean.
It is moral excellence, i.e. Virtue, of course which I mean, because this it is which is concerned with feelings and actions, and in these there can be excess and defect and the mean: it is possible, for instance, to feel the emotions of fear, confidence, lust, anger, compassion, and pleasure and pain generally, too much or too little, and in either case wrongly; but to feel them when we ought, on what occasions, towards whom, why, and as, we should do, is the mean, or in other words the best state, and this is the property of Virtue.
In like manner too with respect to the actions, there may be excess and defect and the mean. Now Virtue is concerned with feelings and actions, in which the excess is wrong and the defect is blamed but the mean is praised
