[¶0] In regard to Justice and Injustice, we have to enquire what sort of actions precisely they are concerned with, in what sense Justice is the observance of a mean, and what are the extremes between which that which is just is a mean. Our enquiry may follow the same procedure as our preceding investigations. Now we observe that everybody means by Justice that moral disposition which renders men apt to do just things, and which causes them to act justly and to wish what is just; and similarly by Injustice that disposition which makes men act unjustly and wish what is unjust. Let us then assume this definition to start with as broadly correct. The fact is that it is not the same with dispositions as with sciences and faculties. It seems that the same faculty or science deals with opposite things; but a disposition or condition which produces a certain result does not also produce the opposite results; for example, health does not give rise to unhealthy actions, but only to healthy ones: healthy walking means walking as a healthy man would walk. Hence sometimes the nature of one of two opposite dispositions is inferred from the other, sometimes dispositions are known from the things in which they are found; for instance, if we know what good bodily condition is, we know from this what bad condition is as well, but we also know what good condition is from bodies in good condition, and know what bodies are in good condition from knowing what good condition is.

> Greek: περὶ δὲ δικαιοσύνης καὶ ἀδικίας σκεπτέον, περὶ ποίας τε τυγχάνουσιν οὖσαι πράξεις, καὶ ποία μεσότης ἐστὶν ἡ δικαιοσύνη, καὶ τὸ δίκαιον τίνων μέσον. ἡ δὲ σκέψις ἡμῖν ἔστω κατὰ τὴν αὐτὴν μέθοδον τοῖς προειρημένοις. ὁρῶμεν δὴ πάντας τὴν τοιαύτην ἕξιν βουλομένους λέγειν δικαιοσύνην, ἀφʼ ἧς πρακτικοὶ τῶν δικαίων εἰσὶ καὶ ἀφʼ ἧς δικαιοπραγοῦσι καὶ βούλονται τὰ δίκαια· τὸν αὐτὸν δὲ τρόπον καὶ περὶ ἀδικίας, ἀφʼ ἧς ἀδικοῦσι καὶ βούλονται τὰ ἄδικα. διὸ καὶ ἡμῖν πρῶτον ὡς ἐν τύπῳ ὑποκείσθω ταῦτα. οὐδὲ γὰρ τὸν αὐτὸν ἔχει τρόπον ἐπί τε τῶν ἐπιστημῶν καὶ δυνάμεων καὶ ἐπὶ τῶν ἕξεων. δύναμις μὲν γὰρ καὶ ἐπιστήμη δοκεῖ τῶν ἐναντίων ἡ αὐτὴ εἶναι, ἕξις δʼ ἡ ἐναντία τῶν ἐναντίων οὔ, οἷον ἀπὸ τῆς ὑγιείας οὐ πράττεται τὰ ἐναντία, ἀλλὰ τὰ ὑγιεινὰ μόνον· λέγομεν γὰρ ὑγιεινῶς βαδίζειν, ὅταν βαδίζῃ ὡς ἂν ὁ ὑγιαίνων. πολλάκις μὲν οὖν γνωρίζεται ἡ ἐναντία ἕξις ἀπὸ τῆς ἐναντίας, πολλάκις δὲ αἱ ἕξεις ἀπὸ τῶν ὑποκειμένων· ἐάν τε γὰρ ἡ εὐεξία ᾖ φανερά, καὶ ἡ καχεξία φανερὰ γίνεται, καὶ ἐκ τῶν εὐεκτικῶν ἡ εὐεξία καὶ ἐκ ταύτης τὰ εὐεκτικά.

[¶1] Thus, supposing good condition is firmness of flesh, bad condition must be flabbiness of flesh, and a diet productive of good condition must be a diet producing firmness of flesh. Also, if one of two correlative groups of words is used in several senses, it follows as a rule that the other is used in several senses too: for example, if “just” has more than one meaning, so also has “unjust” and “Injustice.” Now it appears that the terms Justice and Injustice are used in several senses, but as the equivocal uses are closely connected, the equivocation is not detected; whereas in the case of widely different things called by a common name, the equivocation is comparatively obvious: for example (the difference being considerable when it is one of external form), the equivocal use of the word kleis (key) to denote both the bone at the base of the neck and the instrument with which we lock our doors. Let us then ascertain in how many senses a man is said to be “unjust.” Now the term “unjust” is held to apply both to the man who breaks the law and the man who takes more than his due, the unfair man. Hence it is clear that the law-abiding man and the fair man will both be just. “The just” therefore means that which is lawful and that which is equal or fair, and “the unjust” means that which is illegal and that which is unequal or unfair.

> Greek: εἰ γάρ ἐστιν ἡ εὐεξία πυκνότης σαρκός, ἀνάγκη καὶ τὴν καχεξίαν εἶναι μανότητα σαρκὸς καὶ τὸ εὐεκτικὸν τὸ ποιητικὸν πυκνότητος ἐν σαρκί. ἀκολουθεῖ δʼ ὡς ἐπὶ τὸ πολύ, ἐὰν θάτερον πλεοναχῶς λέγηται, καὶ θάτερον πλεοναχῶς λέγεσθαι, οἷον εἰ τὸ δίκαιον, καὶ τὸ ἄδικον. ἔοικε δὲ πλεοναχῶς λέγεσθαι ἡ δικαιοσύνη καὶ ἡ ἀδικία, ἀλλὰ διὰ τὸ σύνεγγυς εἶναι τὴν ὁμωνυμίαν αὐτῶν λανθάνει καὶ οὐχ ὥσπερ ἐπὶ τῶν πόρρω δήλη μᾶλλον, (ἡ γὰρ διαφορὰ πολλὴ ἡ κατὰ τὴν ἰδέαν) οἷον ὅτι καλεῖται κλεὶς ὁμωνύμως ἥ τε ὑπὸ τὸν αὐχένα τῶν ζῴων καὶ ᾗ τὰς θύρας κλείουσιν. εἰλήφθω δὴ ὁ ἄδικος ποσαχῶς λέγεται. δοκεῖ δὴ ὅ τε παράνομος ἄδικος εἶναι καὶ ὁ πλεονέκτης καὶ ἄνισος, ὥστε δῆλον ὅτι καὶ [ὁ] δίκαιος ἔσται ὅ τε νόμιμος καὶ ὁ ἴσος. τὸ μὲν δίκαιον ἄρα τὸ νόμιμον καὶ τὸ ἴσον, τὸ δʼ ἄδικον τὸ παράνομον καὶ τὸ ἄνισον.

[¶2] Again, as the unjust man is one who takes the larger share, he will be unjust in respect of good things; not all good things, but those on which good and bad fortune depend. These though always good in the absolute sense, are not always good for a particular person. Yet these are the goods men pray for and pursue, although they ought not to do so; they ought, while choosing the things that are good for them, to pray that what is good absolutely may also be good for them. The unjust man does not however always choose the larger share: of things that, speaking absolutely, are bad he chooses the smaller share; but nevertheless he is thought to take more than his due, because the lesser of two evils seems in a sense to be a good, and taking more than one’s due means taking more than one’s due of good. Let us call him “unfair,” for that is a comprehensive term, and includes both taking too much of good things and too little of bad things. Again, we saw that the law-breaker is unjust and the law-abiding man just. It is therefore clear that all lawful things are just in one sense of the word, for what is lawful is decided by legislature, and the several decisions of the legislature we call rules of justice. Now all the various pronouncements of the law aim either at the common interest of all, or at the interest of a ruling class determined either by excellence or in some other similar way; so that in one of its senses the term “just” is applied to anything that produces and preserves the happiness, or the component parts of the happiness, of the political community. But the law also prescribes certain conduct: the conduct of a brave man, for example not to desert one’s post, not to run away, not to throw down one’s arms; that of a temperate man, for example not to commit adultery or outrage; that of a gentle man, for example not to strike, not to speak evil; and so with actions exemplifying the rest of the virtues and vices, commanding these and forbidding those—rightly if the law has been rightly enacted, not so well if it has been made at random.

> Greek: ἐπεὶ δὲ πλεονέκτης ὁ ἄδικος, περὶ τἀγαθὰ ἔσται, οὐ πάντα, ἀλλὰ περὶ ὅσα εὐτυχία καὶ ἀτυχία, ἃ ἐστὶ μὲν ἁπλῶς ἀεὶ ἀγαθά, τινὶ δʼ οὐκ ἀεί. οἱ δʼ ἄνθρωποι ταῦτα εὔχονται καὶ διώκουσιν· δεῖ δʼ οὔ, ἀλλʼ εὔχεσθαι μὲν τὰ ἁπλῶς ἀγαθὰ καὶ αὑτοῖς ἀγαθὰ εἶναι, αἱρεῖσθαι δὲ τὰ αὑτοῖς ἀγαθά. ὁ δʼ ἄδικος οὐκ ἀεὶ τὸ πλέον αἱρεῖται, ἀλλὰ καὶ τὸ ἔλαττον ἐπὶ τῶν ἁπλῶς κακῶν· ἀλλʼ ὅτι δοκεῖ καὶ τὸ μεῖον κακὸν ἀγαθόν πως εἶναι, τοῦ δʼ ἀγαθοῦ ἐστὶν ἡ πλεονεξία, διὰ τοῦτο δοκεῖ πλεονέκτης εἶναι. ἔστι δʼ ἄνισος· τοῦτο γὰρ περιέχει καὶ κοινόν. ἐπεὶ δʼ ὁ παράνομος ἄδικος ἦν ὁ δὲ νόμιμος δίκαιος, δῆλον ὅτι πάντα τὰ νόμιμά ἐστί πως δίκαια· τά τε γὰρ ὡρισμένα ὑπὸ τῆς νομοθετικῆς νόμιμά ἐστι, καὶ ἕκαστον τούτων δίκαιον εἶναί φαμεν. οἱ δὲ νόμοι ἀγορεύουσι περὶ ἁπάντων, στοχαζόμενοι ἢ τοῦ κοινῇ συμφέροντος πᾶσιν ἢ τοῖς ἀρίστοις ἢ τοῖς κυρίοις [κατʼ ἀρετὴν] ἢ κατʼ ἄλλον τινὰ τρόπον τοιοῦτον· ὥστε ἕνα μὲν τρόπον δίκαια λέγομεν τὰ ποιητικὰ καὶ φυλακτικὰ εὐδαιμονίας καὶ τῶν μορίων αὐτῆς τῇ πολιτικῇ κοινωνίᾳ. προστάττει δʼ ὁ νόμος καὶ τὰ τοῦ ἀνδρείου ἔργα ποιεῖν, οἷον μὴ λείπειν τὴν τάξιν μηδὲ φεύγειν μηδὲ ῥιπτεῖν τὰ ὅπλα, καὶ τὰ τοῦ σώφρονος, οἷον μὴ μοιχεύειν μηδʼ ὑβρίζειν, καὶ τὰ τοῦ πράου, οἷον μὴ τύπτειν μηδὲ κακηγορεῖν, ὁμοίως δὲ καὶ κατὰ τὰς ἄλλας ἀρετὰς καὶ μοχθηρίας τὰ μὲν κελεύων τὰ δʼ ἀπαγορεύων, ὀρθῶς μὲν ὁ κείμενος ὀρθῶς, χεῖρον δʼ ὁ ἀπεσχεδιασμένος.

[¶3] Justice then in this sense is perfect Virtue, though with a qualification, namely that it is displayed towards others. This is why Justice is often thought to be the chief of the virtues, and more sublime “or than the evening or the morning star”; and we have the proverb—
In Justice is all Virtue found in sum.
And Justice is perfect virtue because it is the practice of perfect virtue; and perfect in a special degree, because its possessor can practise his virtue towards others and not merely by himself; for there are many who can practise virtue in their own private affairs but cannot do so in their relations with another.

> Greek: αὕτη μὲν οὖν ἡ δικαιοσύνη ἀρετὴ μέν ἐστι τελεία, ἀλλʼ οὐχ ἁπλῶς ἀλλὰ πρὸς ἕτερον. καὶ διὰ τοῦτο πολλάκις κρατίστη τῶν ἀρετῶν εἶναι δοκεῖ ἡ δικαιοσύνη, καὶ οὔθʼ ἕσπερος οὔθʼ ἑῷος οὕτω θαυμαστός· καὶ παροιμιαζόμενοί φαμεν
ἐν δὲ δικαιοσύνῃ συλλήβδην πᾶσʼ ἀρετὴ ἔνι
καὶ τελεία μάλιστα ἀρετή, ὅτι τῆς τελείας ἀρετῆς χρῆσίς ἐστιν. τελεία δʼ ἐστίν, ὅτι ὁ ἔχων αὐτὴν καὶ πρὸς ἕτερον δύναται τῇ ἀρετῇ χρῆσθαι, ἀλλʼ οὐ μόνον καθʼ αὑτόν· πολλοὶ γὰρ ἐν μὲν τοῖς οἰκείοις τῇ ἀρετῇ δύνανται χρῆσθαι, ἐν δὲ τοῖς πρὸς ἕτερον ἀδυνατοῦσιν.

[¶4] This is why we approve the saying of Bias, “Office will show a man”; for in office one is brought into relation with others and becomes a member of a community. The same reason, namely that it involves relationship with someone else, accounts for the view that Justice alone of the virtues is “the good of others,” because it does what is for the advantage of another, either a ruler or an associate. As then the worst man is he who practises vice towards his friends as well as in regard to himself, so the best is not he who practises virtue in regard to himself but he who practises it towards others; for that is a difficult task. Justice in this sense then is not a part of Virtue, but the whole of Virtue; and its opposite Injustice is not a part of Vice but the whole of Vice (the distinction between Virtue and Justice in this sense being clear from what has been said: they are the same quality of mind, but their essence is different; what as displayed in relation to others is Justice, as being simply a disposition of a certain kind is Virtue). What we are investigating, however, is the Justice which is a part of Virtue, since we hold that there is such a thing as Justice in this sense; and similarly we are investigating Injustice in the particular sense. The existence of the latter is proved by the following considerations: (1) When a man displays the other vices—for instance, throws away his shield, from Cowardice, or uses abusive language, from Bad Temper, or refuses to assist a friend with money, from Meanness—though he acts unjustly, he is not taking more than his share of anything; whereas when a man takes more than his share, it is frequently not due to any of these vices, and certainly not to all of them, yet nevertheless the action does display some vice, since we blame it; in fact it displays the vice of Injustice.

> Greek: καὶ διὰ τοῦτο εὖ δοκεῖ ἔχειν τὸ τοῦ Βίαντος, ὅτι ἀρχὴ ἄνδρα δείξει· πρὸς ἕτερον γὰρ καὶ ἐν κοινωνίᾳ ἤδη ὁ ἄρχων. διὰ δὲ τὸ αὐτὸ τοῦτο καὶ ἀλλότριον ἀγαθὸν δοκεῖ εἶναι ἡ δικαιοσύνη μόνη τῶν ἀρετῶν, ὅτι πρὸς ἕτερόν ἐστιν· ἄλλῳ γὰρ τὰ συμφέροντα πράττει, ἢ ἄρχοντι ἢ κοινωνῷ. κάκιστος μὲν οὖν ὁ καὶ πρὸς αὑτὸν καὶ πρὸς τοὺς φίλους χρώμενος τῇ μοχθηρίᾳ, ἄριστος δʼ οὐχ ὁ πρὸς αὑτὸν τῇ ἀρετῇ ἀλλὰ πρὸς ἕτερον· τοῦτο γὰρ ἔργον χαλεπόν. αὕτη μὲν οὖν ἡ δικαιοσύνη οὐ μέρος ἀρετῆς ἀλλʼ ὅλη ἀρετή ἐστιν, οὐδʼ ἡ ἐναντία ἀδικία μέρος κακίας ἀλλʼ ὅλη κακία. τί δὲ διαφέρει ἡ ἀρετὴ καὶ ἡ δικαιοσύνη αὕτη, δῆλον ἐκ τῶν εἰρημένων· ἔστι μὲν γὰρ ἡ αὐτή, τὸ δʼ εἶναι οὐ τὸ αὐτό, ἀλλʼ ᾗ μὲν πρὸς ἕτερον, δικαιοσύνη, ᾗ δὲ τοιάδε ἕξις ἁπλῶς, ἀρετή. ζητοῦμεν δέ γε τὴν ἐν μέρει ἀρετῆς δικαιοσύνην· ἔστι γάρ τις, ὡς φαμέν. ὁμοίως δὲ καὶ περὶ ἀδικίας τῆς κατὰ μέρος. σημεῖον δʼ ὅτι ἔστιν· κατὰ μὲν γὰρ τὰς ἄλλας μοχθηρίας ὁ ἐνεργῶν ἀδικεῖ μέν, πλεονεκτεῖ δʼ οὐδέν, οἷον ὁ ῥίψας τὴν ἀσπίδα διὰ δειλίαν ἢ κακῶς εἰπὼν διὰ χαλεπότητα ἢ οὐ βοηθήσας χρήμασι διʼ ἀνελευθερίαν· ὅταν δὲ πλεονεκτῇ, πολλάκις κατʼ οὐδεμίαν τῶν τοιούτων, ἀλλὰ μὴν οὐδὲ κατὰ πάσας, κατὰ πονηρίαν δέ γε τινά (ψέγομεν γάρ) καὶ κατʼ ἀδικίαν.

[¶5] Therefore there is another sort of Injustice, which is a part of Injustice in the universal sense, and there is something unjust which is a part of the unjust in general, or illegal. (2) Again, suppose two men to commit adultery, one for profit, and gaining by the act, the other from desire, and having to pay, and so losing by it: then the latter would be deemed to be a profligate rather than a man who takes more than his due, while the former would be deemed unjust, but not profligate; clearly therefore it is being done for profit that makes the action unjust. (3) Again, whereas all other unjust acts are invariably ascribed to some particular vice—for example, adultery is put down to Profligacy, desertion from the ranks to Cowardice, assault to Anger—an unjust act by which a man has profited is not attributed to any vice except Injustice. Hence it is manifest that there is another sort of Injustice besides universal Injustice, the former being a part of the latter. It is called by the same name because its definition falls in the same genus, both sorts of Injustice being exhibited in a man’s relation to others; but whereas Injustice in the particular sense is concerned with honor or money or security, or whatever term we may employ to include all these things, its motive being the pleasure of gain, Injustice in the universal sense is concerned with all the things that are the sphere of Virtue.

> Greek: ἔστιν ἄρʼ ἄλλη τις ἀδικία ὡς μέρος τῆς ὅλης, καὶ ἄδικόν τι ἐν μέρει τοῦ ὅλου ἀδίκου τοῦ παρὰ τὸν νόμον. ἔτι εἰ ὃ μὲν τοῦ κερδαίνειν ἕνεκα μοιχεύει καὶ προσλαμβάνων, ὃ δὲ προστιθεὶς καὶ ζημιούμενος διʼ ἐπιθυμίαν, οὗτος μὲν ἀκόλαστος δόξειεν ἂν εἶναι μᾶλλον ἢ πλεονέκτης, ἐκεῖνος δʼ ἄδικος, ἀκόλαστος δʼ οὔ· δῆλον ἄρα ὅτι διὰ τὸ κερδαίνειν. ἔτι περὶ μὲν τἆλλα πάντα ἀδικήματα γίνεται ἡ ἐπαναφορὰ ἐπί τινα μοχθηρίαν ἀεί, οἷον εἰ ἐμοίχευσεν, ἐπʼ ἀκολασίαν, εἰ ἐγκατέλιπε τὸν παραστάτην, ἐπὶ δειλίαν, εἰ ἐπάταξεν, ἐπʼ ὀργήν· εἰ δʼ ἐκέρδανεν, ἐπʼ οὐδεμίαν μοχθηρίαν ἀλλʼ ἢ ἐπʼ ἀδικίαν. ὥστε φανερὸν ὅτι ἔστι τις ἀδικία παρὰ τὴν ὅλην ἄλλη ἐν μέρει, συνώνυμος, ὅτι ὁ ὁρισμὸς ἐν τῷ αὐτῷ γένει·

[¶6] Thus it is clear that there are more kinds of Justice than one, and that the term has another meaning besides Virtue as a whole. We have then to ascertain the nature and attributes of Justice in this special sense. Now we have distinguished two meanings of “the unjust,” namely the unlawful and the unequal or unfair, and two meanings of “the just,” namely the lawful and the equal or fair. Injustice then, in the sense previously mentioned, corresponds to the meaning “unlawful”; but since the unfair is not the same as the unlawful, but different from it, and related to it as part to whole (for not everything unlawful is unfair, though everything unfair is unlawful), so also the unjust and Injustice in the particular sense are not the same as the unjust and Injustice in the universal sense, but different from them, and related to them as part to whole; for Injustice in this sense is a part of universal Injustice, and similarly the Justice we are now considering is a part of universal Justice. We have therefore to discuss Justice and Injustice, and the just and unjust, in the particular sense. We may then set aside that Justice which is coextensive with virtue in general, being the practice of virtue in general towards someone else, and that Injustice which is the practice of vice in general towards someone else.

> Greek: ἄμφω γὰρ ἐν τῷ πρὸς ἕτερον ἔχουσι τὴν δύναμιν, ἀλλʼ ἣ μὲν περὶ τιμὴν ἢ χρήματα ἢ σωτηρίαν, ἢ εἴ τινι ἔχοιμεν ἑνὶ ὀνόματι περιλαβεῖν ταῦτα πάντα, καὶ διʼ ἡδονὴν τὴν ἀπὸ τοῦ κέρδους, ἣ δὲ περὶ ἅπαντα περὶ ὅσα ὁ σπουδαῖος. ὅτι μὲν οὖν εἰσὶν αἱ δικαιοσύναι πλείους, καὶ ὅτι ἔστι τις καὶ ἑτέρα παρὰ τὴν ὅλην ἀρετήν, δῆλον· τίς δὲ καὶ ποία τις, ληπτέον. διώρισται δὴ τὸ ἄδικον τό τε παράνομον καὶ τὸ ἄνισον, τὸ δὲ δίκαιον τό τε νόμιμον καὶ τὸ ἴσον. κατὰ μὲν οὖν τὸ παράνομον ἡ πρότερον εἰρημένη ἀδικία ἐστίν. ἐπεὶ δὲ τὸ ἄνισον καὶ τὸ παράνομον οὐ ταὐτὸν ἀλλʼ ἕτερον ὡς μέρος πρὸς ὅλον (τὸ μὲν γὰρ ἄνισον ἅπαν παράνομον, τὸ δὲ παράνομον οὐχ ἅπαν ἄνισον), καὶ τὸ ἄδικον καὶ ἡ ἀδικία οὐ ταὐτὰ ἀλλʼ ἕτερα ἐκείνων, τὰ μὲν ὡς μέρη τὰ δʼ ὡς ὅλα· μέρος γὰρ αὕτη ἡ ἀδικία τῆς ὅλης ἀδικίας, ὁμοίως δὲ καὶ ἡ δικαιοσύνη τῆς δικαιοσύνης. ὥστε καὶ περὶ τῆς ἐν μέρει δικαιοσύνης καὶ περὶ τῆς ἐν μέρει ἀδικίας λεκτέον, καὶ τοῦ δικαίου καὶ ἀδίκου ὡσαύτως. ἡ μὲν οὖν κατὰ τὴν ὅλην ἀρετὴν τεταγμένη δικαιοσύνη καὶ ἀδικία, ἣ μὲν τῆς ὅλης ἀρετῆς οὖσα χρῆσις πρὸς ἄλλον ἣ δὲ τῆς κακίας, ἀφείσθω.

[¶7] It is also clear how we should define what is just and unjust in the corresponding senses. For the actions that spring from virtue in general are in the main identical with the actions that are according to law, since the law enjoins conduct displaying the various particular virtues and forbids conduct displaying the various particular vices. Also the regulations laid down for the education that fits a man for social life are the rules productive of virtue in general. As for the education of the individual as such, that makes a man simply a good man, the question whether this is the business of Political Science or of some other science must be determined later: for it would seem that to be a good man is not in every case the same thing as to be a good citizen. Particular Justice on the other hand, and that which is just in the sense corresponding to it, is divided into two kinds. One kind is exercised in the distribution of honor, wealth, and the other divisible assets of the community, which may be allotted among its members in equal or unequal shares.

> Greek: καὶ τὸ δίκαιον δὲ καὶ τὸ ἄδικον τὸ κατὰ ταύτας φανερὸν ὡς διοριστέον· σχεδὸν γὰρ τὰ πολλὰ τῶν νομίμων τὰ ἀπὸ τῆς ὅλης ἀρετῆς προσταττόμενά ἐστιν· καθʼ ἑκάστην γὰρ ἀρετὴν προστάττει ζῆν καὶ καθʼ ἑκάστην μοχθηρίαν κωλύει ὁ νόμος. τὰ δὲ ποιητικὰ τῆς ὅλης ἀρετῆς ἐστὶ τῶν νομίμων ὅσα νενομοθέτηται περὶ παιδείαν τὴν πρὸς τὸ κοινόν. περὶ δὲ τῆς καθʼ ἕκαστον παιδείας, καθʼ ἣν ἁπλῶς ἀνὴρ ἀγαθός ἐστι, πότερον τῆς πολιτικῆς ἐστὶν ἢ ἑτέρας, ὕστερον διοριστέον· οὐ γὰρ ἴσως ταὐτὸν ἀνδρί τʼ ἀγαθῷ εἶναι καὶ πολίτῃ παντί. τῆς δὲ κατὰ μέρος δικαιοσύνης καὶ τοῦ κατʼ αὐτὴν δικαίου ἓν μέν ἐστιν εἶδος τὸ ἐν ταῖς διανομαῖς τιμῆς ἢ χρημάτων ἢ τῶν ἄλλων ὅσα μεριστὰ τοῖς κοινωνοῦσι τῆς πολιτείας (ἐν τούτοις γὰρ ἔστι καὶ ἄνισον ἔχειν καὶ ἴσον ἕτερον ἑτέρου), ἓν δὲ τὸ ἐν τοῖς συναλλάγμασι διορθωτικόν.

[¶8] The other kind is that which supplies a corrective principle in private transactions. This Corrective Justice again has two sub-divisions, corresponding to the two classes of private transactions, those which are voluntary and those which are involuntary. Examples of voluntary transactions are selling, buying, lending at interest, pledging, lending without interest, depositing, letting for hire; these transactions being termed voluntary because they are voluntarily entered upon. Of involuntary transactions some are furtive, for instance, theft, adultery, poisoning, procuring, enticement of slaves, assassination, false witness; others are violent, for instance, assault, imprisonment, murder, robbery with violence, maiming, abusive language, contumelious treatment. Now since an unjust man is one who is unfair, and the unjust is the unequal, it is clear that corresponding to the unequal there is a mean, namely that which is equal; for every action admitting of more and less admits of the equal also. If then the unjust is the unequal, the just is the equal—a view that commends itself to all without proof; and since the equal is a mean, the just will be a sort of mean too. Again, equality involves two terms at least. It accordingly follows not only (a) that the just is a mean and equal [and relative to something and just for certain persons ], but also (b) that, as a mean, it implies certain extremes between which it lies, namely the more and the less; (c) that, as equal, it implies two shares that are equal; and (d) that, as just, it implies certain persons for whom it is just. It follows therefore that justice involves at least four terms, namely, two persons for whom it is just and two shares which are just.

> Greek: τούτου δὲ μέρη δύο· τῶν γὰρ συναλλαγμάτων τὰ μὲν ἑκούσιά ἐστι τὰ δʼ ἀκούσια, ἑκούσια μὲν τὰ τοιάδε οἷον πρᾶσις ὠνὴ δανεισμὸς ἐγγύη χρῆσις παρακαταθήκη μίσθωσις (ἑκούσια δὲ λέγεται, ὅτι ἡ ἀρχὴ τῶν συναλλαγμάτων τούτων ἑκούσιος), τῶν δʼ ἀκουσίων τὰ μὲν λαθραῖα, οἷον κλοπὴ μοιχεία φαρμακεία προαγωγεία δουλαπατία δολοφονία ψευδομαρτυρία, τὰ δὲ βίαια, οἷον αἰκία δεσμὸς θάνατος ἁρπαγὴ πήρωσις κακηγορία προπηλακισμός. ἐπεὶ δʼ ὅ τʼ ἄδικος ἄνισος καὶ τὸ ἄδικον ἄνισον, δῆλον ὅτι καὶ μέσον τι ἔστι τοῦ ἀνίσου. τοῦτο δʼ ἐστὶ τὸ ἴσον· ἐν ὁποίᾳ γὰρ πράξει ἔστι τὸ πλέον καὶ τὸ ἔλαττον, ἔστι καὶ τὸ ἴσον. εἰ οὖν τὸ ἄδικον ἄνισον, τὸ δίκαιον ἴσον· ὅπερ καὶ ἄνευ λόγου δοκεῖ πᾶσιν. ἐπεὶ δὲ τὸ ἴσον μέσον, τὸ δίκαιον μέσον τι ἂν εἴη. ἔστι δὲ τὸ ἴσον ἐν ἐλαχίστοις δυσίν. ἀνάγκη τοίνυν τὸ δίκαιον μέσον τε καὶ ἴσον εἶναι καὶ πρός τι καὶ τισίν, καὶ ᾗ μὲν μέσον, τινῶν (ταῦτα δʼ ἐστὶ πλεῖον καὶ ἔλαττον), ᾗ δʼ ἴσον, δυοῖν, ᾗ δὲ δίκαιον, τισίν. ἀνάγκη ἄρα τὸ δίκαιον ἐν ἐλαχίστοις εἶναι τέτταρσιν· οἷς τε γὰρ δίκαιον τυγχάνει ὄν, δύο ἐστί, καὶ ἐν οἷς, τὰ πράγματα, δύο.

[¶9] And there will be the same equality between the shares as between the persons, since the ratio between the shares will be equal to the ratio between the persons; for if the persons are not equal, they will not have equal shares; it is when equals possess or are allotted unequal shares, or persons not equal equal shares, that quarrels and complaints arise. This is also clear from the principle of “assignment by desert.” All are agreed that justice in distributions must be based on desert of some sort, although they do not all mean the same sort of desert; democrats make the criterion free birth; those of oligarchical sympathies wealth, or in other cases birth; upholders of aristocracy make it virtue. Justice is therefore a sort of proportion; for proportion is not a property of numerical quantity only, but of quantity in general, proportion being equality of ratios, and involving four terms at least. (That a discrete proportion has four terms is plain, but so also has a continuous proportion, since it treats one term as two, and repeats it:

> Greek: καὶ ἡ αὐτὴ ἔσται ἰσότης, οἷς καὶ ἐν οἷς· ὡς γὰρ ἐκεῖνα ἔχει, τὰ ἐν οἷς, οὕτω κἀκεῖνα ἔχει· εἰ γὰρ μὴ ἴσοι, οὐκ ἴσα ἕξουσιν, ἀλλʼ ἐντεῦθεν αἱ μάχαι καὶ τὰ ἐγκλήματα, ὅταν ἢ μὴ ἴσα ἴσοι ἢ μὴ ἴσοι ἴσα ἔχωσι καὶ νέμωνται. ἔτι ἐκ τοῦ κατʼ ἀξίαν τοῦτο δῆλον· τὸ γὰρ δίκαιον ἐν ταῖς νομαῖς ὁμολογοῦσι πάντες κατʼ ἀξίαν τινὰ δεῖν εἶναι, τὴν μέντοι ἀξίαν οὐ τὴν αὐτὴν λέγουσι πάντες [ὑπάρχειν], ἀλλʼ οἱ μὲν δημοκρατικοὶ ἐλευθερίαν, οἱ δʼ ὀλιγαρχικοὶ πλοῦτον, οἳ δʼ εὐγένειαν, οἱ δʼ ἀριστοκρατικοὶ ἀρετήν. ἔστιν ἄρα τὸ δίκαιον ἀνάλογόν τι. τὸ γὰρ ἀνάλογον οὐ μόνον ἐστὶ μοναδικοῦ ἀριθμοῦ ἴδιον, ἀλλʼ ὅλως ἀριθμοῦ· ἡ γὰρ ἀναλογία ἰσότης ἐστὶ λόγων, καὶ ἐν τέτταρσιν ἐλαχίστοις. ἡ μὲν οὖν διῃρημένη ὅτι ἐν τέτταρσι, δῆλον. ἀλλὰ καὶ ἡ συνεχής· τῷ γὰρ ἑνὶ ὡς δυσὶ χρῆται καὶ δὶς λέγει, οἷον ὡς ἡ τοῦ α πρὸς τὴν τοῦ β, οὕτως ἡ τοῦ β πρὸς τὴν τοῦ γ.

[¶10] for example, as the line representing term one is to the line representing term two, so is the line representing term two to the line representing term three; here the line representing term two is mentioned twice, so that if it be counted twice, there will be four proportionals.) Thus the just also involves four terms at least, and the ratio between the first pair of terms is the same as that between the second pair. For the two lines representing the persons and shares are similarly divided; then, as the first term is to the second, so is the third to the fourth; and hence, by alternation, as the first is to the third, so is the second to the fourth; and therefore also, as the first is to the second, so is the sum of the first and third to the sum of the second and fourth. Now this is the combination effected by a distribution of shares, and the combination is a just one, if persons and shares are added together in this way. The principle of Distributive Justice, therefore, is the conjunction of the first term of a proportion with the third and of the second with the fourth; and the just in this sense is a mean between two extremes that are disproportionate, since the proportionate is a mean, and the just is the proportionate. (This kind of proportion is termed by mathematicians geometrical proportion; for a geometrical proportion is one in which the sum of the first and third terms will bear the same ratio to the sum of the second and fourth as one term of either pair bears to the other term.— Distributive justice is not a continuous proportion, for its second and third terms, a person and a share, do not constitute a single term.) The just in this sense is therefore the proportionate, and the unjust is that which violates proportion. The unjust may therefore be either too much or too little; and this is what we find in fact, for when injustice is done, the doer has too much and the sufferer too little of the good in question; though vice versa in the case of an evil, because a lesser evil in comparison with a greater counts as a good, since the lesser of two evils is more desirable than the greater, but what is desirable is good, and the more desirable it is, the greater good it is.

> Greek: δὶς οὖν ἡ τοῦ β εἴρηται· ὥστʼ ἐὰν ἡ τοῦ β τεθῇ δίς, τέτταρα ἔσται τὰ ἀνάλογα. ἔστι δὲ καὶ τὸ δίκαιον ἐν τέτταρσιν ἐλαχίστοις, καὶ ὁ λόγος ὁ αὐτός· διῄρηται γὰρ ὁμοίως οἷς τε καὶ ἅ. ἔσται ἄρα ὡς ὁ α ὅρος πρὸς τὸν β, οὕτως ὁ γ πρὸς τὸν δ, καὶ ἐναλλὰξ ἄρα, ὡς ὁ α πρὸς τὸν γ, ὁ β πρὸς τὸν δ. ὥστε καὶ τὸ ὅλον πρὸς τὸ ὅλον· ὅπερ ἡ νομὴ συνδυάζει, κἂν οὕτω συντεθῇ, δικαίως συνδυάζει. ἡ ἄρα τοῦ α ὅρου τῷ γ καὶ ἡ τοῦ β τῷ δ σύζευξις τὸ ἐν διανομῇ δίκαιόν ἐστι, καὶ μέσον τὸ δίκαιον τοῦτʼ ἐστί, ⟨τὸ δʼ ἄδικον⟩ τὸ παρὰ τὸ ἀνάλογον· τὸ γὰρ ἀνάλογον μέσον, τὸ δὲ δίκαιον ἀνάλογον. καλοῦσι δὲ τὴν τοιαύτην ἀναλογίαν γεωμετρικὴν οἱ μαθηματικοί· ἐν γὰρ τῇ γεωμετρικῇ συμβαίνει καὶ τὸ ὅλον πρὸς τὸ ὅλον ὅπερ ἑκάτερον πρὸς ἑκάτερον. ἔστι δʼ οὐ συνεχὴς αὕτη ἡ ἀναλογία· οὐ γὰρ γίνεται εἷς ἀριθμῷ ὅρος, ᾧ καὶ ὅ. τὸ μὲν οὖν δίκαιον τοῦτο, τὸ ἀνάλογον· τὸ δʼ ἄδικον τὸ παρὰ τὸ ἀνάλογον. γίνεται ἄρα τὸ μὲν πλέον τὸ δʼ ἔλαττον, ὅπερ καὶ ἐπὶ τῶν ἔργων συμβαίνει· ὁ μὲν γὰρ ἀδικῶν πλέον ἔχει, ὁ δʼ ἀδικούμενος ἔλαττον τοῦ ἀγαθοῦ.

[¶11] This then is one kind of Justice. The remaining kind is Corrective Justice, which operates in private transactions, both voluntary and involuntary. This justice is of a different sort from the preceding. For justice in distributing common property always conforms with the proportion we have described (since when a distribution is made from the common stock, it will follow the same ratio as that between the amounts which the several persons have contributed to the common stock); and the injustice opposed to justice of this a kind is a violation of this proportion. But the just in private transactions, although it is the equal in a sense (and the unjust the unequal), is not the equal according to geometrical but according to arithmetical proportion.

> Greek: ἐπὶ δὲ τοῦ κακοῦ ἀνάπαλιν· ἐν ἀγαθοῦ γὰρ λόγῳ γίνεται τὸ ἔλαττον κακὸν πρὸς τὸ μεῖζον κακόν· ἔστι γὰρ τὸ ἔλαττον κακὸν μᾶλλον αἱρετὸν τοῦ μείζονος, τὸ δʼ αἱρετὸν ἀγαθόν, καὶ τὸ μᾶλλον μεῖζον. τὸ μὲν οὖν ἓν εἶδος τοῦ δικαίου τοῦτʼ ἐστίν. τὸ δὲ λοιπὸν ἓν τὸ διορθωτικόν, ὃ γίνεται ἐν τοῖς συναλλάγμασι καὶ τοῖς ἑκουσίοις καὶ τοῖς ἀκουσίοις. τοῦτο δὲ τὸ δίκαιον ἄλλο εἶδος ἔχει τοῦ πρότερον. τὸ μὲν γὰρ διανεμητικὸν δίκαιον τῶν κοινῶν ἀεὶ κατὰ τὴν ἀναλογίαν ἐστὶ τὴν εἰρημένην· καὶ γὰρ ἀπὸ χρημάτων κοινῶν ἐὰν γίνηται ἡ διανομή, ἔσται κατὰ τὸν λόγον τὸν αὐτὸν ὅνπερ ἔχουσι πρὸς ἄλληλα τὰ εἰσενεχθέντα· καὶ τὸ ἄδικον τὸ ἀντικείμενον τῷ δικαίῳ τούτῳ τὸ παρὰ τὸ ἀνάλογόν ἐστιν. τὸ δʼ ἐν τοῖς συναλλάγμασι δίκαιον ἐστὶ μὲν ἴσον τι, καὶ τὸ ἄδικον ἄνισον, ἀλλʼ οὐ κατὰ τὴν ἀναλογίαν ἐκείνην ἀλλὰ κατὰ τὴν ἀριθμητικήν.

[¶12] For it makes no difference whether a good man has defrauded a bad man or a bad one a good one, nor whether it is a good or a bad man that has committed adultery; the law looks only at the nature of damage, treating the parties as equal, and merely asking whether one has done and the other suffered injustice, whether one inflicted and the other has sustained damage. Hence the unjust being here the unequal, the judge endeavors to equalize it: inasmuch as when one man has received and the other has inflicted a blow, or one has killed and the other been killed, the line representing the suffering and doing of the deed is divided into unequal parts, but the judge endeavors to make them equal by the penalty or loss he imposes, taking away the gain. (For the term “gain” is used in a general way to apply to such cases, even though it is not strictly appropriate to some of them, for example to a person who strikes another, nor is “loss” appropriate to the victim in this case; but at all events the results are called “loss” and “gain” respectively when the amount of the damage sustained comes to be estimated.) Thus, while the equal is a mean between more and less, gain and loss are at once both more and less in contrary ways, more good and less evil being gain and more evil and less good loss; and as the equal, which we pronounce to be just, is, as we said, a mean between them, it follows that Justice in Rectification will be the mean between loss and gain. This is why when disputes occur men have recourse to a judge.

> Greek: οὐδὲν γὰρ διαφέρει, εἰ ἐπιεικὴς φαῦλον ἀπεστέρησεν ἢ φαῦλος ἐπιεικῆ, οὐδʼ εἰ ἐμοίχευσεν ἐπιεικὴς ἢ φαῦλος· ἀλλὰ πρὸς τοῦ βλάβους τὴν διαφορὰν μόνον βλέπει ὁ νόμος, καὶ χρῆται ὡς ἴσοις, εἰ ὃ μὲν ἀδικεῖ ὃ δʼ ἀδικεῖται, καὶ εἰ ἔβλαψεν ὃ δὲ βέβλαπται. ὥστε τὸ ἄδικον τοῦτο ἄνισον ὂν ἰσάζειν πειρᾶται ὁ δικαστής· καὶ γὰρ ὅταν ὃ μὲν πληγῇ ὃ δὲ πατάξῃ, ἢ καὶ κτείνῃ ὃ δʼ ἀποθάνῃ, διῄρηται τὸ πάθος καὶ ἡ πρᾶξις εἰς ἄνισα· ἀλλὰ πειρᾶται τῇ ζημίᾳ ἰσάζειν, ἀφαιρῶν τοῦ κέρδους. λέγεται γὰρ ὡς ἁπλῶς εἰπεῖν ἐπὶ τοῖς τοιούτοις, κἂν εἰ μή τισιν οἰκεῖον ὄνομα εἴη, τὸ κέρδος, οἷον τῷ πατάξαντι, καὶ ἡ ζημία τῷ παθόντι· ἀλλʼ ὅταν γε μετρηθῇ τὸ πάθος, καλεῖται τὸ μὲν ζημία τὸ δὲ κέρδος. ὥστε τοῦ μὲν πλείονος καὶ ἐλάττονος τὸ ἴσον μέσον, τὸ δὲ κέρδος καὶ ἡ ζημία τὸ μὲν πλέον τὸ δʼ ἔλαττον ἐναντίως, τὸ μὲν τοῦ ἀγαθοῦ πλέον τοῦ κακοῦ δʼ ἔλαττον κέρδος, τὸ δʼ ἐναντίον ζημία· ὧν ἦν μέσον τὸ ἴσον, ὃ λέγομεν εἶναι δίκαιον· ὥστε τὸ ἐπανορθωτικὸν δίκαιον ἂν εἴη τὸ μέσον ζημίας καὶ κέρδους. διὸ καὶ ὅταν ἀμφισβητῶσιν, ἐπὶ τὸν δικαστὴν καταφεύγουσιν·

[¶13] To go to a judge is to go to justice, for the ideal judge is so to speak justice personified. Also, men require a judge to be a middle term or medium—indeed in some places judges are called mediators—, for they think that if they get the mean they will get what is just. Thus the just is a sort of mean, inasmuch as the judge is a medium between the litigants. Now the judge restores equality: if we represent the matter by a line divided into two unequal parts, he takes away from the greater segment that portion by which it exceeds one-half of the whole line, and adds it to the lesser segment. When the whole has been divided into two halves, people then say that they “have their own,” having got what is equal. This is indeed the origin of the word dikaion (just): it means dicha (in half), as if one were to pronounce it dichaion; and a dikast (judge) is a dichast (halver). The equal is a mean by way of arithmetical proportion between the greater and the less. For when of two equals a part is taken from the one and added to the other, the latter will exceed the former by twice that part, since if it had been taken from the one but not added to the other, the latter would exceed the former by once the part in question only.

> Greek: τὸ δʼ ἐπὶ τὸν δικαστὴν ἰέναι ἰέναι ἐστὶν ἐπὶ τὸ δίκαιον· ὁ γὰρ δικαστὴς βούλεται εἶναι οἷον δίκαιον ἔμψυχον· καὶ ζητοῦσι δικαστὴν μέσον, καὶ καλοῦσιν ἔνιοι μεσιδίους, ὡς ἐὰν τοῦ μέσου τύχωσι, τοῦ δικαίου τευξόμενοι. μέσον ἄρα τι τὸ δίκαιον, εἴπερ καὶ ὁ δικαστής. ὁ δὲ δικαστὴς ἐπανισοῖ, καὶ ὥσπερ γραμμῆς εἰς ἄνισα τετμημένης, ᾧ τὸ μεῖζον τμῆμα τῆς ἡμισείας ὑπερέχει, τοῦτʼ ἀφεῖλε καὶ τῷ ἐλάττονι τμήματι προσέθηκεν. ὅταν δὲ δίχα διαιρεθῇ τὸ ὅλον, τότε φασὶν ἔχειν τὸ αὑτοῦ ὅταν λάβωσι τὸ ἴσον. τὸ δʼ ἴσον μέσον ἐστὶ τῆς μείζονος καὶ ἐλάττονος κατὰ τὴν ἀριθμητικὴν ἀναλογίαν. διὰ τοῦτο καὶ ὀνομάζεται δίκαιον, ὅτι δίχα ἐστίν, ὥσπερ ἂν εἴ τις εἴποι δίχαιον, καὶ ὁ δικαστὴς διχαστής. ἐπὰν γὰρ δύο ἴσων ἀφαιρεθῇ ἀπὸ θατέρου, πρὸς θάτερον δὲ προστεθῇ, δυσὶ τούτοις ὑπερέχει θάτερον· εἰ γὰρ ἀφῃρέθη μέν, μὴ προσετέθη δέ, ἑνὶ ἂν μόνον ὑπερεῖχεν.

[¶14] Therefore the latter will exceed the mean by once the part, and the mean will exceed the former, from which the part was taken, by once that part. This process then will enable us to ascertain what we ought to take away from the party that has too much and what to add to the one that has too little: we must add to the one that has too little the amount whereby the mean between them exceeds him, and take away from the greatest of the three the amount by which the mean is exceeded by him. Let the lines AA, BB, CC be equal to one another; let the segment AE be taken away from the line AA, and let the segment CD be added to the line CC, so that the whole line DCC exceeds the line EA by CD+CF; then DCC will exceed BB by CD. The terms “loss” and “gain” in these cases are borrowed from the operations of voluntary exchange. There, to have more than one’s own is called gaining, and to have less than one had at the outset is called losing, as for instance in buying and selling, and all other transactions sanctioned by law; while if the result of the transaction is neither an increase nor a decrease, but exactly what the parties had of themselves, they say they “have their own” and have neither lost nor gained. Hence Justice in Involuntary Transactions is a mean between gain and loss in a sense: it is to have after the transaction an amount equal to the amount one had before it.

> Greek: τοῦ μέσου ἄρα ἑνί, καὶ τὸ μέσον, ἀφʼ οὗ ἀφῃρέθη, ἑνί. τούτῳ ἄρα γνωριοῦμεν τί τε ἀφελεῖν δεῖ ἀπὸ τοῦ πλέον ἔχοντος, καὶ τί προσθεῖναι τῷ ἔλαττον ἔχοντι· ᾧ μὲν γὰρ τὸ μέσον ὑπερέχει, τοῦτο προσθεῖναι δεῖ τῷ ἔλαττον ἔχοντι, ᾧ δʼ ὑπερέχεται, ἀφελεῖν ἀπὸ τοῦ μεγίστου. ἴσαι αἱ ἐφʼ ὧν αα ββ γγ ἀλλήλαις· ἀπὸ τῆς αα ἀφῃρήσθω τὸ αε, καὶ προσκείσθω τῇ γγ τὸ ἐφʼ ᾧ γδ, ὥστε ὅλη ἡ δγγ τῆς εα ὑπερέχει τῷ γδ καὶ τῷ γζ· τῆς ἄρα ββ τῷ γδ. [ἔστι δὲ τοῦτο καὶ ἐπὶ τῶν ἄλλων τεχνῶν· ἀνῃροῦντο γὰρ ἄν, εἰ μὴ ἐποίει τὸ ποιοῦν καὶ ὅσον καὶ οἷον, καὶ τὸ πάσχον ἔπασχε τοῦτο καὶ τοσοῦτον καὶ τοιοῦτον.] ἐλήλυθε δὲ τὰ ὀνόματα ταῦτα, ἥ τε ζημία καὶ τὸ κέρδος, ἐκ τῆς ἑκουσίου ἀλλαγῆς· τὸ μὲν γὰρ πλέον ἔχειν ἢ τὰ αὑτοῦ κερδαίνειν λέγεται, τὸ δʼ ἔλαττον τῶν ἐξ ἀρχῆς ζημιοῦσθαι, οἷον ἐν τῷ ὠνεῖσθαι καὶ πωλεῖν καὶ ἐν ὅσοις ἄλλοις ἄδειαν δέδωκεν ὁ νόμος· ὅταν δὲ μήτε πλέον μήτʼ ἔλαττον ἀλλʼ αὐτὰ ⟨τὰ⟩ διʼ αὐτῶν γένηται, τὰ αὑτῶν φασὶν ἔχειν καὶ οὔτε ζημιοῦσθαι οὔτε κερδαίνειν. ὥστε κέρδους τινὸς καὶ ζημίας μέσον τὸ δίκαιόν ἐστι τῶν παρὰ τὸ ἑκούσιον, τὸ ἴσον ἔχειν καὶ πρότερον καὶ ὕστερον.

[¶15] The view is also held by some that simple Reciprocity is Justice. This was the doctrine of the Pythagoreans, who defined the just simply as “suffering reciprocally with another.” Reciprocity however does not coincide either with Distributive or with Corrective Justice (although people mean to identify it with the latter when they quote the rule of Rhadamanthys—
An a man suffer even that which he did,
Right justice will be done). For in many cases Reciprocity is at variance with Justice: for example, if an officer strikes a man, it is wrong for the man to strike him back; and if a man strikes an officer, it is not enough for the officer to strike him, but he ought to be punished as well. Again, it makes a great difference whether an act was done with or without the consent of the other party. But in the interchange of services Justice in the form of Reciprocity is the bond that maintains the association: reciprocity, that is, on the basis of proportion, not on the basis of equality. The very existence of the state depends on proportionate reciprocity; for men demand that they shall be able to requite evil with evil— if they cannot, they feel they are in the position of slaves—and to repay good with good— failing which, no exchange takes place, and it is exchange that binds them together.

> Greek: δοκεῖ δέ τισι καὶ τὸ ἀντιπεπονθὸς εἶναι ἁπλῶς δίκαιον, ὥσπερ οἱ Πυθαγόρειοι ἔφασαν· ὡρίζοντο γὰρ ἁπλῶς τὸ δίκαιον τὸ ἀντιπεπονθὸς ἄλλῳ. τὸ δʼ ἀντιπεπονθὸς οὐκ ἐφαρμόττει οὔτʼ ἐπὶ τὸ νεμητικὸν δίκαιον οὔτʼ ἐπὶ τὸ διορθωτικόν—καίτοι βούλονταί γε τοῦτο λέγειν καὶ τὸ Ῥαδαμάνθυος δίκαιον·
εἴ κε πάθοι τά τʼ ἔρεξε, δίκη κʼ ἰθεῖα γένοιτο
—πολλαχοῦ γὰρ διαφωνεῖ· οἷον εἰ ἀρχὴν ἔχων ἐπάταξεν, οὐ δεῖ ἀντιπληγῆναι, καὶ εἰ ἄρχοντα ἐπάταξεν, οὐ πληγῆναι μόνον δεῖ ἀλλὰ καὶ κολασθῆναι. ἔτι τὸ ἑκούσιον καὶ τὸ ἀκούσιον διαφέρει πολύ. ἀλλʼ ἐν μὲν ταῖς κοινωνίαις ταῖς ἀλλακτικαῖς συνέχει τὸ τοιοῦτον δίκαιον, τὸ ἀντιπεπονθὸς κατʼ ἀναλογίαν καὶ μὴ κατʼ ἰσότητα. τῷ ἀντιποιεῖν γὰρ ἀνάλογον συμμένει ἡ πόλις. ἢ γὰρ τὸ κακῶς ζητοῦσιν·

[¶16] This is why we set up a shrine of the Graces in a public place, to remind men to return a kindness; for that is a special characteristic of grace, since it is a duty not only to repay a service done one, but another time to take the initiative in doing a service oneself. Now proportionate requital is effected by diagonal conjunction. For example, let A be a builder, B a shoemaker, C a house, and D a shoe. It is required that the builder shall receive from the shoemaker a portion of the product of his labor, and give him a portion of the product of his own. Now if proportionate equality between the products be first established, and then reciprocation take place, the requirement indicated will have been achieved; but if this is not done, the bargain is not equal, and intercourse does not continue. For it may happen that the product of one of the parties is worth more than that of the other, and in that case therefore they have to be equalized. This holds good with the other arts as well; for they would have passed out of existence if the active element did not produce, and did not receive the equivalent in quantity and quality of what the passive element receives. For an association for interchange of services is not formed between two physicians, but between a physician and a farmer, and generally between persons who are different, and who may be unequal, though in that case they have to be equalized. Hence all commodities exchanged must be able to be compared in some way.

> Greek: εἰ δὲ μή, δουλεία δοκεῖ εἶναι [εἰ μὴ ἀντιποιήσει]· ἢ τὸ εὖ· εἰ δὲ μή, μετάδοσις οὐ γίνεται, τῇ μεταδόσει δὲ συμμένουσιν. διὸ καὶ Χαρίτων ἱερὸν ἐμποδὼν ποιοῦνται, ἵνʼ ἀνταπόδοσις ᾖ· τοῦτο γὰρ ἴδιον χάριτος· ἀνθυπηρετῆσαι γὰρ δεῖ τῷ χαρισαμένῳ, καὶ πάλιν αὐτὸν ἄρξαι χαριζόμενον. ποιεῖ δὲ τὴν ἀντίδοσιν τὴν κατʼ ἀναλογίαν ἡ κατὰ διάμετρον σύζευξις. οἰκοδόμος ἐφʼ ᾧ α, σκυτοτόμος ἐφʼ ᾧ β, οἰκία ἐφʼ ᾧ γ, ὑπόδημα ἐφʼ ᾧ δ. δεῖ οὖν λαμβάνειν τὸν οἰκοδόμον παρὰ τοῦ σκυτοτόμου τὸ ἐκείνου ἔργον, καὶ αὐτὸν ἐκείνῳ μεταδιδόναι τὸ αὑτοῦ. ἐὰν οὖν πρῶτον ᾖ τὸ κατὰ τὴν ἀναλογίαν ἴσον, εἶτα τὸ ἀντιπεπονθὸς γένηται, ἔσται τὸ λεγόμενον. εἰ δὲ μή, οὐκ ἴσον, οὐδὲ συμμένει· οὐθὲν γὰρ κωλύει κρεῖττον εἶναι τὸ θατέρου ἔργον ἢ τὸ θατέρου· δεῖ οὖν ταῦτα ἰσασθῆναι. ἔστι δὲ τοῦτο καὶ ἐπὶ τῶν ἄλλων τεχνῶν· ἀνῃροῦντο γὰρ ἄν, εἰ μὴ ⟨ὃ⟩ ἐποίει τὸ ποιοῦν καὶ ὅσον καὶ οἷον, καὶ τὸ πάσχον ἔπασχε τοῦτο καὶ τοσοῦτον καὶ τοιοῦτον. οὐ γὰρ ἐκ δύο ἰατρῶν γίνεται κοινωνία, ἀλλʼ ἐξ ἰατροῦ καὶ γεωργοῦ, καὶ ὅλως ἑτέρων καὶ οὐκ ἴσων· ἀλλὰ τούτους δεῖ ἰσασθῆναι. διὸ πάντα συμβλητὰ δεῖ πως εἶναι, ὧν ἐστὶν ἀλλαγή.

[¶17] It is to meet this requirement that men have introduced money; money constitutes in a manner a middle term, for it is a measure of all things, and so of their superior or inferior value, that is to say, how many shoes are equivalent to a house or to a given quantity of food. As therefore a builder is to a shoemaker, so must such and such a number of shoes be to a house, [or to a given quantity of food]; for without this reciprocal proportion, there can be no exchange and no association; and it cannot be secured unless the commodities in question be equal in a sense. It is therefore necessary that all commodities shall be measured by some one standard, as was said before. And this standard is in reality demand, which is what holds everything together, since if men cease to have wants or if their wants alter, exchange will go on no longer, or will be on different lines. But demand has come to be conventionally represented by money; this is why money is called nomisma (customary currency), because it does not exist by nature but by custom (nomos), and can be altered and rendered useless at will. There will therefore be reciprocal proportion when the products have been equated, so that as farmer is to shoemaker, so may the shoemaker’s product be to the farmer’s product.

> Greek: ἐφʼ ὃ τὸ νόμισμʼ ἐλήλυθε, καὶ γίνεταί πως μέσον· πάντα γὰρ μετρεῖ, ὥστε καὶ τὴν ὑπεροχὴν καὶ τὴν ἔλλειψιν, πόσα ἄττα δὴ ὑποδήματʼ ἴσον οἰκίᾳ ἢ τροφῇ. δεῖ τοίνυν ὅπερ οἰκοδόμος πρὸς σκυτοτόμον, τοσαδὶ ὑποδήματα πρὸς οἰκίαν ἢ τροφήν. εἰ γὰρ μὴ τοῦτο, οὐκ ἔσται ἀλλαγὴ οὐδὲ κοινωνία. τοῦτο δʼ, εἰ μὴ ἴσα εἴη πως, οὐκ ἔσται. δεῖ ἄρα ἑνί τινι πάντα μετρεῖσθαι, ὥσπερ ἐλέχθη πρότερον. τοῦτο δʼ ἐστὶ τῇ μὲν ἀληθείᾳ ἡ χρεία, ἣ πάντα συνέχει· εἰ γὰρ μηθὲν δέοιντο ἢ μὴ ὁμοίως, ἢ οὐκ ἔσται ἀλλαγὴ ἢ οὐχ ἡ αὐτή· οἷον δʼ ὑπάλλαγμα τῆς χρείας τὸ νόμισμα γέγονε κατὰ συνθήκην· καὶ διὰ τοῦτο τοὔνομα ἔχει νόμισμα, ὅτι οὐ φύσει ἀλλὰ νόμῳ ἐστί, καὶ ἐφʼ ἡμῖν μεταβαλεῖν καὶ ποιῆσαι ἄχρηστον. ἔσται δὴ ἀντιπεπονθός, ὅταν ἰσασθῇ, ὥστε ὅπερ γεωργὸς πρὸς σκυτοτόμον, τὸ ἔργον τὸ τοῦ σκυτοτόμου πρὸς τὸ τοῦ γεωργοῦ.

[¶18] And when they exchange their products they must reduce them to the form of a proportion, otherwise one of the two extremes will have both the excesses; whereas when they have their own, they then are equal, and can form an association together, because equality in this sense can be established in their case (farmer A, food C, shoemaker B, shoemaker’s product equalized D ); whereas if it were impossible for reciprocal proportion to be effected in this way, there could be no association between them. That it is demand which, by serving as a single standard, holds such an association together, is shown by the fact that, when there is no demand for mutual service on the part of both or at least of one of the parties, no exchange takes place between them [as when someone needs something that one has oneself, for instance the state offering a license to export corn in exchange for wine]. This inequality of demand has therefore to be equalized. Now money serves us as a guarantee of exchange in the future: supposing we need nothing at the moment, it ensures that exchange shall be possible when a need arises, for it meets the requirement of something we can produce in payment so as to obtain the thing we need. Money, it is true, is liable to the same fluctuation of demand as other commodities, for its purchasing power varies at different times; but it tends to be comparatively constant. Hence the proper thing is for all commodities to have their prices fixed; this will ensure that exchange, and consequently association, shall always be possible. Money then serves as a measure which makes things commensurable and so reduces them to equality. If there were no exchange there would be no association, and there can be no exchange without equality, and no equality without commensurability. Though therefore it is impossible for things so different to become commensurable in the strict sense, our demand furnishes a sufficiently accurate common measure for practical purposes.

> Greek: εἰς σχῆμα δʼ ἀναλογίας οὐ δεῖ ἄγειν, ὅταν ἀλλάξωνται (εἰ δὲ μή, ἀμφοτέρας ἕξει τὰς ὑπεροχὰς τὸ ἕτερον ἄκρον), ἀλλʼ ὅταν ἔχωσι τὰ αὑτῶν. οὕτως ἴσοι καὶ κοινωνοί, ὅτι αὕτη ἡ ἰσότης δύναται ἐπʼ αὐτῶν γίνεσθαι. γεωργὸς α, τροφὴ γ, σκυτοτόμος β, τὸ ἔργον αὐτοῦ τὸ ἰσασμένον δ. εἰ δʼ οὕτω μὴ ἦν ἀντιπεπονθέναι, οὐκ ἂν ἦν κοινωνία. ὅτι δʼ ἡ χρεία συνέχει ὥσπερ ἕν τι ὄν, δηλοῖ ὅτι ὅταν μὴ ἐν χρείᾳ ὦσιν ἀλλήλων, ἢ ἀμφότεροι ἢ ἅτερος, οὐκ ἀλλάττονται, †ὥσπερ ὅταν οὗ ἔχει αὐτὸς δέηταί τις, οἷον οἴνου, διδόντες σίτου ἐξαγωγήν.† δεῖ ἄρα τοῦτο ἰσασθῆναι. ὑπὲρ δὲ τῆς μελλούσης ἀλλαγῆς, εἰ νῦν μηδὲν δεῖται, ὅτι ἔσται ἂν δεηθῇ, τὸ νόμισμα οἷον ἐγγυητής ἐσθʼ ἡμῖν· δεῖ γὰρ τοῦτο φέροντι εἶναι λαβεῖν. πάσχει μὲν οὖν καὶ τοῦτο τὸ αὐτό· οὐ γὰρ ἀεὶ ἴσον δύναται· ὅμως δὲ βούλεται μένειν μᾶλλον. διὸ δεῖ πάντα τετιμῆσθαι· οὕτω γὰρ ἀεὶ ἔσται ἀλλαγή, εἰ δὲ τοῦτο, κοινωνία. τὸ δὴ νόμισμα ὥσπερ μέτρον σύμμετρα ποιῆσαν ἰσάζει· οὔτε γὰρ ἂν μὴ οὔσης ἀλλαγῆς κοινωνία ἦν, οὔτʼ ἀλλαγὴ ἰσότητος μὴ οὔσης, οὔτʼ ἰσότης μὴ οὔσης συμμετρίας. τῇ μὲν οὖν ἀληθείᾳ ἀδύνατον τὰ τοσοῦτον διαφέροντα σύμμετρα γενέσθαι, πρὸς δὲ τὴν χρείαν ἐνδέχεται ἱκανῶς.

[¶19] There must therefore be some one standard, and this accepted by agreement (which is why it is called nomisma, customary currency); for such a standard makes all things commensurable, since all things can be measured by money. Let A be a house, B ten minae and C a bedstead. Then A=B/2 (supposing the house to be worth, or equal to, five minae), and C (the bedstead) =B/10; it is now clear how many bedsteads are equal to one house, namely five. It is clear that before money existed this is how the rate of exchange was actually stated—five beds for a house—since there is no real difference between that and the price of five beds for a house. We have now stated what Justice and Injustice are in principle. From the definition given, it is plain that just conduct is a mean between doing and suffering injustice, for the former is to have too much and the latter to have too little. And Justice is a mode of observing the mean, though not in the same way as the other virtues are, but because it is related to a mean, while Injustice is related to the extremes.

> Greek: ἓν δή τι δεῖ εἶναι, τοῦτο δʼ ἐξ ὑποθέσεως· διὸ νόμισμα καλεῖται· τοῦτο γὰρ πάντα ποιεῖ σύμμετρα· μετρεῖται γὰρ πάντα νομίσματι. οἰκία α, μναῖ δέκα β, κλίνη γ. τὸ α τοῦ β ἥμισυ, εἰ πέντε μνῶν ἀξία ἡ οἰκία, ἢ ἴσον· ἡ δὲ κλίνη δέκατον μέρος, τὸ γ τοῦ β· δῆλον τοίνυν πόσαι κλῖναι ἴσον οἰκίᾳ, ὅτι πέντε. ὅτι δʼ οὕτως ἡ ἀλλαγὴ ἦν πρὶν τὸ νόμισμα εἶναι, δῆλον· διαφέρει γὰρ οὐδὲν ἢ κλῖναι πέντε ἀντὶ οἰκίας, ἢ ὅσου αἱ πέντε κλῖναι. τί μὲν οὖν τὸ ἄδικον καὶ τί τὸ δίκαιόν ἐστιν, εἴρηται. διωρισμένων δὲ τούτων δῆλον ὅτι ἡ δικαιοπραγία μέσον ἐστὶ τοῦ ἀδικεῖν καὶ ἀδικεῖσθαι· τὸ μὲν γὰρ πλέον ἔχειν τὸ δʼ ἔλαττόν ἐστιν. ἡ δὲ δικαιοσύνη μεσότης τίς ἐστιν, οὐ τὸν αὐτὸν δὲ τρόπον ταῖς ἄλλαις ἀρεταῖς, ἀλλʼ ὅτι μέσου ἐστίν· ἡ δʼ ἀδικία τῶν ἄκρων.
