This is the reason why not all things are according to law, because there are things about which it is simply impossible to lay down a law, and so we want special enactments for particular cases. For to speak generally, the rule of the undefined must be itself undefined also, just as the rule to measure Lesbian building is made of lead: for this rule shifts according to the form of each stone and the special enactment according to the facts of the case in question.

[Sidenote: 1138a] It is clear then what the Equitable is; namely that it is Just but better than one form of Just: and hence it appears too who the Equitable man is: he is one who has a tendency to choose and carry out these principles, and who is not apt to press the letter of the law on the worse side but content to waive his strict claims though backed by the law: and this moral state is Equity, being a species of Justice, not a different moral state from Justice.

XI

The answer to the second of the two questions indicated above, "whether it is possible for a man to deal unjustly by himself," is obvious from what has been already stated. In the first place, one cla.s.s of Justs is those which are enforced by law in accordance with Virtue in the most extensive sense of the term: for instance, the law does not bid a man kill himself; and whatever it does not bid it forbids: well, whenever a man does hurt contrary to the law (unless by way of requital of hurt), voluntarily, i.e. knowing to whom he does it and wherewith, he acts Unjustly. Now he that from rage kills himself, voluntarily, does this in contravention of Right Reason, which the law does not permit. He therefore acts Unjustly: but towards whom? towards the Community, not towards himself (because he suffers with his own consent, and no man can be Unjustly dealt with with his own consent), and on this principle the Community punishes him; that is a certain infamy is attached to the suicide as to one who acts Unjustly towards the Community.

Next, a man cannot deal Unjustly by himself in the sense in which a man is Unjust who only does Unjust acts without being entirely bad (for the two things are different, because the Unjust man is in a way bad, as the coward is, not as though he were chargeable with badness in the full extent of the term, and so he does not act Unjustly in this sense), because if it were so then it would be possible for the same thing to have been taken away from and added to the same person: but this is really not possible, the Just and the Unjust always implying a plurality of persons.

Again, an Unjust action must be voluntary, done of deliberate purpose, and aggressive (for the man who hurts because he has first suffered and is merely requiting the same is not thought to act Unjustly), but here the man does to himself and suffers the same things at the same time.

Again, it would imply the possibility of being Unjustly dealt with with one's own consent.

And, besides all this, a man cannot act Unjustly without his act falling under some particular crime; now a man cannot seduce his own wife, commit a burglary on his own premises, or steal his own property. After all, the general answer to the question is to allege what was settled respecting being Unjustly dealt with with one's own consent.

It is obvious, moreover, that being Unjustly dealt by and dealing Unjustly by others are both wrong; because the one is having less, the other having more, than the mean, and the case is parallel to that of the healthy in the healing art, and that of good condition in the art of training: but still the dealing Unjustly by others is the worst of the two, because this involves wickedness and is blameworthy; wickedness, I mean, either wholly, or nearly so (for not all voluntary wrong implies injustice), but the being Unjustly dealt by does not involve wickedness or injustice.

[Sidenote: 1138b] In itself then, the being Unjustly dealt by is the least bad, but accidentally it may be the greater evil of the two.

However, scientific statement cannot take in such considerations; a pleurisy, for instance, is called a greater physical evil than a bruise: and yet this last may be the greater accidentally; it may chance that a bruise received in a fall may cause one to be captured by the enemy and slain.

Further: Just, in the way of metaphor and similitude, there may be I do not say between a man and himself exactly but between certain parts of his nature; but not Just of every kind, only such as belongs to the relation of master and slave, or to that of the head of a family. For all through this treatise the rational part of the Soul has been viewed as distinct from the irrational.

Now, taking these into consideration, there is thought to be a possibility of injustice towards one's self, because herein it is possible for men to suffer somewhat in contradiction of impulses really their own; and so it is thought that there is Just of a certain kind between these parts mutually, as between ruler and ruled.

Let this then be accepted as an account of the distinctions which we recognise respecting Justice and the rest of the moral virtues.

BOOK VI

I having stated in a former part of this treatise that men should choose the mean instead of either the excess or defect, and that the mean is according to the dictates of Right Reason; we will now proceed to explain this term.

For in all the habits which we have expressly mentioned, as likewise in all the others, there is, so to speak, a mark with his eye fixed on which the man who has Reason tightens or slacks his rope; and there is a certain limit of those mean states which we say are in accordance with Right Reason, and lie between excess on the one hand and defect on the other.

Now to speak thus is true enough but conveys no very definite meaning: as, in fact, in all other pursuits requiring attention and diligence on which skill and science are brought to bear; it is quite true of course to say that men are neither to labour nor relax too much or too little, but in moderation, and as Right Reason directs; yet if this were all a man had he would not be greatly the wiser; as, for instance, if in answer to the question, what are proper applications to the body, he were to be told, "Oh! of course, whatever the science of medicine, and in such manner as the physician, directs."

And so in respect of the mental states it is requisite not merely that this should be true which has been already stated, but further that it should be expressly laid down what Right Reason is, and what is the definition of it.

[Sidenote: 1139a] Now in our division of the Excellences of the Soul, we said there were two cla.s.ses, the Moral and the Intellectual: the former we have already gone through; and we will now proceed to speak of the others, premising a few words respecting the Soul itself. It was stated before, you will remember, that the Soul consists of two parts, the Rational, and Irrational: we must now make a similar division of the Rational.

Let it be understood then that there are two parts of the Soul possessed of Reason; one whereby we realise those existences whose causes cannot be otherwise than they are, and one whereby we realise those which can be otherwise than they are (for there must be, answering to things generically different, generically different parts of the soul naturally adapted to each, since these parts of the soul possess their knowledge in virtue of a certain resemblance and appropriateness in themselves to the objects of which they are percipients); and let us name the former, "that which is apt to know," the latter, "that which is apt to calculate" (because deliberating and calculating are the same, and no one ever deliberates about things which cannot be otherwise than they are: and so the Calculative will be one part of the Rational faculty of the soul).

We must discover, then, which is the best state of each of these, because that will be the Excellence of each; and this again is relative to the work each has to do.

II

There are in the Soul three functions on which depend moral action and truth; Sense, Intellect, Appet.i.tion, whether vague Desire or definite Will. Now of these Sense is the originating cause of no moral action, as is seen from the fact that brutes have Sense but are in no way partakers of moral action.

[Intellect and Will are thus connected,] what in the Intellectual operation is Affirmation and Negation that in the Will is Pursuit and Avoidance, And so, since Moral Virtue is a State apt to exercise Moral Choice and Moral Choice is Will consequent on deliberation, the Reason must be true and the Will right, to const.i.tute good Moral Choice, and what the Reason affirms the Will must pursue. Now this Intellectual operation and this Truth is what bears upon Moral Action; of course truth and falsehood than the conclusion such knowledge as he has will be merely accidental.

IV

[Sidenote:1140a] Let thus much be accepted as a definition of Knowledge.

Matter which may exist otherwise than it actually does in any given case (commonly called Contingent) is of two kinds, that which is the object of Making, and that which is the object of Doing; now Making and Doing are two different things (as we show in the exoteric treatise), and so that state of mind, conjoined with Reason, which is apt to Do, is distinct from that also conjoined with Reason, which is apt to Make: and for this reason they are not included one by the other, that is, Doing is not Making, nor Making Doing. Now as Architecture is an Art, and is the same as "a certain state of mind, conjoined with Reason, which is apt to Make," and as there is no Art which is not such a state, nor any such state which is not an Art, Art, in its strict and proper sense, must be "a state of mind, conjoined with true Reason, apt to Make."

Now all Art has to do with production, and contrivance, and seeing how any of those things may be produced which may either be or not be, and the origination of which rests with the maker and not with the thing made.

And, so neither things which exist or come into being necessarily, nor things in the way of nature, come under the province of Art, because these are self-originating. And since Making and Doing are distinct, Art must be concerned with the former and not the latter. And in a certain sense Art and Fortune are concerned with the same things, as, Agathon says by the way,

"Art Fortune loves, and is of her beloved."

So Art, as has been stated, is "a certain state of mind, apt to Make, conjoined with true Reason;" its absence, on the contrary, is the same state conjoined with false Reason, and both are employed upon Contingent matter.

V

As for Practical Wisdom, we shall ascertain its nature by examining to what kind of persons we in common language ascribe it.

[Sidenote: 1140b] It is thought then to be the property of the Practically Wise man to be able to deliberate well respecting what is good and expedient for himself, not in any definite line, as what is conducive to health or strength, but what to living well. A proof of this is that we call men Wise in this or that, when they calculate well with a view to some good end in a case where there is no definite rule. And so, in a general way of speaking, the man who is good at deliberation will be Practically Wise. Now no man deliberates respecting things which cannot be otherwise than they are, nor such as lie not within the range of his own action: and so, since Knowledge requires strict demonstrative reasoning, of which Contingent matter does not admit (I say Contingent matter, because all matters of deliberation must be Contingent and deliberation cannot take place with respect to things which are Necessarily), Practical Wisdom cannot be Knowledge nor Art; nor the former, because what falls under the province of Doing must be Contingent; not the latter, because Doing and Making are different in kind.

It remains then that it must be "a state of mind true, conjoined with Reason, and apt to Do, having for its object those things which are good or bad for Man:" because of Making something beyond itself is always the object, but cannot be of Doing because the very well-doing is in itself an End.

For this reason we think Pericles and men of that stamp to be Practically Wise, because they can see what is good for themselves and for men in general, and we also think those to be such who are skilled in domestic management or civil government. In fact, this is the reason why we call the habit of perfected self-mastery by the name which in Greek it bears, etymologically signifying "that which preserves the Practical Wisdom:" for what it does preserve is the Notion I have mentioned, _i.e._ of one's own true interest, For it is not every kind of Notion which the pleasant and the painful corrupt and pervert, as, for instance, that "the three angles of every rectilineal triangle are equal to two right angles," but only those bearing on moral action.

For the Principles of the matters of moral action are the final cause of them: now to the man who has been corrupted by reason of pleasure or pain the Principle immediately becomes obscured, nor does he see that it is his duty to choose and act in each instance with a view to this final cause and by reason of it: for viciousness has a tendency to destroy the moral Principle: and so Practical Wisdom must be "a state conjoined with reason, true, having human good for its object, and apt to do."

Then again Art admits of degrees of excellence, but Practical Wisdom does not: and in Art he who goes wrong purposely is preferable to him who does so unwittingly, but not so in respect of Practical Wisdom or the other Virtues. It plainly is then an Excellence of a certain kind, and not an Art.

Now as there are two parts of the Soul which have Reason, it must be the Excellence of the Opinionative [which we called before calculative or deliberative], because both Opinion and Practical Wisdom are exercised upon Contingent matter. And further, it is not simply a state conjoined with Reason, as is proved by the fact that such a state may be forgotten and so lost while Practical Wisdom cannot.

VI

Now Knowledge is a conception concerning universals and Necessary matter, and there are of course certain First Principles in all trains of demonstrative reasoning (that is of all Knowledge because this is connected with reasoning): that faculty, then, which takes in the first principles of that which comes under the range of Knowledge, cannot be either Knowledge, or Art, or Practical Wisdom: not Knowledge, because what is the object of Knowledge must be derived from demonstrative reasoning; not either of the other two, because they are exercised upon Contingent matter only. [Sidenote: 1141a] Nor can it be Science which takes in these, because the Scientific Man must in some cases depend on demonstrative Reasoning.

It comes then to this: since the faculties whereby we always attain truth and are never deceived when dealing with matter Necessary or even Contingent are Knowledge, Practical Wisdom, Science, and Intuition, and the faculty which takes in First Principles cannot be any of the three first; the last, namely Intuition, must be it which performs this function.

VII

Science is a term we use princ.i.p.ally in two meanings: in the first place, in the Arts we ascribe it to those who carry their arts to the highest accuracy; Phidias, for instance, we call a Scientific or cunning sculptor; Polycleitus a Scientific or cunning statuary; meaning, in this instance, nothing else by Science than an excellence of art: in the other sense, we think some to be Scientific in a general way, not in any particular line or in any particular thing, just as Homer says of a man in his Margites; "Him the G.o.ds made neither a digger of the ground, nor ploughman, nor in any other way Scientific."

So it is plain that Science must mean the most accurate of all Knowledge; but if so, then the Scientific man must not merely know the deductions from the First Principles but be in possession of truth respecting the First Principles. So that Science must be equivalent to Intuition and Knowledge; it is, so to speak, Knowledge of the most precious objects, _with a head on_.

I say of the most precious things, because it is absurd to suppose [Greek: politikae], or Practical Wisdom, to be the highest, unless it can be shown that Man is the most excellent of all that exists in the Universe. Now if "healthy" and "good" are relative terms, differing when applied to men or to fish, but "white" and "straight" are the same always, men must allow that the Scientific is the same always, but the Practically Wise varies: for whatever provides all things well for itself, to this they would apply the term Practically Wise, and commit these matters to it; which is the reason, by the way, that they call some brutes Practically Wise, such that is as plainly have a faculty of forethought respecting their own subsistence.

And it is quite plain that Science and [Greek: politikae] cannot be identical: because if men give the name of Science to that faculty which is employed upon what is expedient for themselves, there will be many instead of one, because there is not one and the same faculty employed on the good of all animals collectively, unless in the same sense as you may say there is one art of healing with respect to all living beings.

[Sidenote: 1141b] If it is urged that man is superior to all other animals, that makes no difference: for there are many other things more G.o.dlike in their nature than Man, as, most obviously, the elements of which the Universe is composed.
