Nicomachean Ethics

use. But the virtues we acquire by doing the acts, as is the case with the arts too. We learn an art by doing that which we wish to do when we have learned it; we become builders by building, and harpers by harping. And so by doing just acts we become just, and by doing acts of temperance and courage we become temperate and courageous.
This is attested, too, by what occurs in states; for the legislators make their citizens good by training;  i.e. this is the wish of all legislators, and those who do not succeed in this miss their aim, and it is this that distinguishes a good from a bad constitution.
Again, both the moral virtues and the corresponding vices result from and are formed by the same acts; and this is the case with the arts also. It is by harping that good harpers and bad harpers alike are produced: and so with builders and the rest; by building well they will become good builders, and bad builders by building badly. Indeed, if it were not so, they would not want anybody to teach them, but would all be born either good or bad at their trades. And it is just the same with the virtues also. It is by our conduct in our intercourse with other men that we become just or unjust, and by acting in circumstances of danger, and training ourselves to feel fear or confidence, that we become courageous or cowardly. So, too, with our animal appetites and the passion of anger; for by behaving in this way or in that on the occasions with which these passions are concerned, some become temperate and gentle, and others profligate and ill-tempered. In a word, acts of any kind produce habits or characters of the same kind.
Hence we ought to make sure that our acts be of a certain kind; for the resulting character varies as they vary. It makes no small difference, therefore, whether a man be trained from his youth up in this way or in that, but a great difference, or rather all the difference.

But our present inquiry has not, like the rest, a merely speculative aim; we are not inquiring merely in order to know what excellence or virtue is, but in order to become good; for otherwise it would profit us nothing. We must ask therefore about these acts, and see of what kind they are to be; for, as we said, it is they that determine our habits or character.
First of all, then, that they must be in accordance with right reason is a common characteristic of them, which we shall here take for granted, reserving for future discussion 21 the question what this right reason is, and how it is related to the other excellences.
But let it be understood, before we go on, that all reasoning on matters of practice must be in outline merely, and not scientifically exact: for, as we said at starting, the kind of reasoning to be demanded varies with the subject in hand; and in practical matters and questions of expediency there are no invariable laws, any more than in questions of health.
And if our general conclusions are thus inexact, still more inexact is all reasoning about particular cases; for these fall under no system of scientifically established rules or traditional maxims, but the agent must always consider for himself what the special occasion requires, just as in medicine or navigation.
But though this is the case we must try to render what help we can.
First of all, then, we must observe that, in matters of this sort, to fall short and to exceed are alike fatal. This is plain (to illustrate what we cannot see by what we can see) in the case of strength and health. Too much and too little exercise alike destroy strength, and to take too much meat and drink, or to take too little, is equally ruinous to health, but the fitting amount produces and increases and preserves them. Just so, then, is it with temperance also, and courage, and the other virtues. The man who shuns and fears everything and never makes a stand, becomes a coward; while the man who fears nothing at all, but will face anything, becomes foolhardy. So, too, the man who takes his fill of any kind of pleasure, and abstains from none, is a profligate, but the man who shuns all (like him whom we call a “boor”) is devoid of sensibility. 22 Thus temperance and courage are destroyed both by excess and defect, but preserved by moderation.
But habits or types of character are not only produced and preserved and destroyed by the same occasions and the same means, but they will also manifest themselves in the same circumstances. This is the case with palpable things like strength. Strength is produced by taking plenty of nourishment and doing plenty of hard work, and the strong man, in turn, has the greatest capacity for these. And the case is the same with the virtues: by abstaining from pleasure we become temperate, and when we have become temperate we are best able to abstain. And so with courage: by habituating ourselves to despise danger, and to face it, we become courageous; and when we have become courageous, we are best able to face danger.


III
The pleasure or pain that accompanies the acts must be taken as a test of the formed habit or character.
He who abstains from the pleasures of the body and rejoices in the abstinence is temperate, while he who is vexed at having to abstain is profligate; and again, he who faces danger with pleasure, or, at any rate, without pain, is courageous, but he to whom this is painful is a coward.
For moral virtue or excellence is closely concerned with pleasure and pain. It is pleasure that moves us to do what is base, and
