course: but clearly there is in them, beside the Reason, some other natural principle which fights with and strains against the Reason. (For in plain terms, just as paralysed limbs of the body when their owners would move them to the right are borne aside in a contrary direction to the left, so is it in the case of the Soul, for the impulses of men who cannot control their appetites are to contrary points: the difference is that in the case of the body we do see what is borne aside but in the case of the soul we do not. But, it may be, not the less on that account are we to suppose that there is in the Soul also somewhat besides the Reason, which is opposed to this and goes against it; as to how it is different, that is irrelevant.)
But of Reason this too does evidently partake, as we have said: for instance, in the man of self-control it obeys Reason: and perhaps in the man of perfected self-mastery, or the brave man, it is yet more obedient; in them it agrees entirely with the Reason.
So then the Irrational is plainly twofold: the one part, the merely vegetative, has no share of Reason, but that of desire, or appetition generally, does partake of it in a sense, in so far as it is obedient to it and capable of submitting to its rule. (So too in common phrase we say we have [Greek: logos] of our father or friends, and this in a different sense from that in which we say we have [Greek: logos] of mathematics.)
Now that the Irrational is in some way persuaded by the Reason, admonition, and every act of rebuke and exhortation indicate. If then we are to say that this also has Reason, then the Rational, as well as the Irrational, will be twofold, the one supremely and in itself, the other paying it a kind of filial regard.
The Excellence of Man then is divided in accordance with this difference: we make two classes, calling the one Intellectual, and the other Moral; pure science, intelligence, and practical wisdom—Intellectual: liberality, and perfected self-mastery—Moral: in speaking of a man's Moral character, we do not say he is a scientific or intelligent but a meek man, or one of perfected self-mastery: and we praise the man of science in right of his mental state; and of these such as are praiseworthy we call Excellences.
BOOK II
Well: human Excellence is of two kinds, Intellectual and Moral: now the Intellectual springs originally, and is increased subsequently, from teaching (for the most part that is), and needs therefore experience and time; whereas the Moral comes from custom, and so the Greek term denoting it is but a slight deflection from the term denoting custom in that language.
From this fact it is plain that not one of the Moral Virtues comes to be in us merely by nature: because of such things as exist by nature, none can be changed by custom: a stone, for instance, by nature gravitating downwards, could never by custom be brought to ascend, not even if one were to try and accustom it by throwing it up ten thousand times; nor could file again be brought to descend, nor in fact could anything whose nature is in one way be brought by custom to be in another. The Virtues then come to be in us neither by nature, nor in despite of nature, but we are furnished by nature with a capacity for receiving themu and are perfected in them through custom.
Again, in whatever cases we get things by nature, we get the faculties first and perform the acts of working afterwards; an illustration of which is afforded by the case of our bodily senses, for it was not from having often seen or heard that we got these senses, but just the reverse: we had them and so exercised them, but did not have them because we had exercised them. But the Virtues we get by first performing single acts of working, which, again, is the case of other things, as the arts for instance; for what we have to make when we have learned how, these we learn how to make by making: men come to be builders, for instance, by building; harp-players, by playing on the harp: exactly so, by doing just actions we come to be just; by doing the actions of self-mastery we come to be perfected in self-mastery; and by doing brave actions brave.
And to the truth of this testimony is borne by what takes place in communities: because the law-givers make the individual members good men by habituation, and this is the intention certainly of every law-giver, and all who do not effect it well fail of their intent; and herein consists the difference between a good Constitution and a bad.
Again, every Virtue is either produced or destroyed from and by the very same circumstances: art too in like manner; I mean it is by playing the harp that both the good and the bad harp-players are formed: and similarly builders and all the rest; by building well men will become good builders; by doing it badly bad ones: in fact, if this had not been so, there would have been no need of instructors, but all men would have been at once good or bad in their several arts without them.
So too then is it with the Virtues: for by acting in the various relations in which we are thrown with our fellow men, we come to be, some just, some unjust: and by acting in dangerous positions and being habituated to feel fear or confidence, we come to be, some brave, others cowards.
Similarly is it also with respect to the occasions of lust and anger: for some men come to be perfected in self-mastery and mild, others destitute of all self-control and passionate; the one class by behaving in one way under them, the other by behaving in another. Or, in one word, the habits are produced from the acts of working like to them: and so what we have to do is to give a certain character to these particular acts, because the habits formed correspond to the differences of these.
So then, whether we are accustomed this way or that straight from childhood, makes not a small but an important difference, or rather I would say it makes all the difference.
II
Since then the object of the present treatise is not mere speculation, as it is of some others (for we are inquiring not merely that we may know what virtue is but that we may become virtuous, else it would have been useless), we must consider as to the particular actions how we are to do them, because, as we have just said, the quality of the habits that shall be formed depends on these.
Now, that we are to act in accordance with Right Reason is a general maxim, and may for the present be taken for granted: we will speak of it hereafter, and say both what Right Reason is, and what are its relations to the other virtues.
[Sidenote: 1104a]
But let this point be first thoroughly understood between us, that all which can be said on moral action must be said in outline, as it were, and not exactly: for as we remarked at the commencement, such reasoning only must be required as the nature of the subject-matter admits of, and matters of moral action and expediency have no fixedness any more than matters of health. And if the subject in its general maxims is such, still less in its application to particular cases is exactness attainable: because these fall not under any art or system of rules, but it must be left in each instance to the individual agents to look to the exigencies of the particular case, as it is in the art of healing, or that of navigating a ship. Still, though the present subject is confessedly such, we must try and do what we can for it.
First then this must be noted, that it is the nature of such things to be spoiled by defect and excess; as we see in the case of health and strength (since for the illustration of things which cannot be seen we must use those that can), for excessive training impairs the strength as well as deficient: meat and drink, in like manner, in too great or too small quantities, impair the health: while in due proportion they cause, increase, and preserve it.
Thus it is therefore with the habits of perfected Self-Mastery and Courage and the rest of the Virtues: for the man who flies from and fears all things, and never stands up against anything, comes to be a coward; and he who fears nothing, but goes at everything, comes to be rash. In like manner too, he that tastes of every pleasure and abstains from none comes to lose all self-control; while he who avoids all, as do the dull and clownish, comes as it were to lose his faculties of perception: that is to say, the habits of perfected Self-Mastery and Courage are spoiled by the excess and defect, but by the mean state are preserved.
Furthermore, not only do the origination, growth, and marring of the habits come from and by the same circumstances, but also the
