We see then that all men mean by the term Justice a moral state such that in consequence of it men have the capacity of doing what is just, and actually do it, and wish it:[1] similarly also with respect to Injustice, a moral state such that in consequence of it men do unjustly and wish what is unjust: let us also be content then with these as a ground-work sketched out. I mention the two, because the same does not hold with regard to States whether of mind or body as with regard to Sciences or Faculties: I mean that whereas it is thought that the same Faculty or Science embraces contraries, a State will not: from health, for instance, not the contrary acts are done but the healthy ones only; we say a man walks healthily when he walks as the healthy man would. However, of the two contrary states the one may be frequently known from the other, and oftentimes the states from their subject-matter: if it be seen clearly what a good state of body is, then is it also seen what a bad state is, and from the things which belong to a good state of body the good state itself is seen, and _vice versâ_. If, for instance, the good state is firmness of flesh it follows that the bad state is flabbiness of flesh; and whatever causes firmness of flesh is connected with the good state. It follows moreover in general,[2] that if of two contrary terms the one is used in many senses so also will the other be; as, for instance, if “the Just,” then also “the Unjust.” Now Justice and Injustice do seem to be used respectively in many senses, but, because the line of demarcation between these is very fine and minute,[3] it commonly escapes notice that they are thus used, and it is not plain and manifest as where the various significations of terms are widely different for in these last the visible difference is great, for instance, the word κλεὶς is used equivocally to denote the bone which is under the neck of animals and the instrument with which people close doors. Let it be ascertained then in how many senses the term “Unjust man” is used. Well, he who violates the law, and he who is a grasping man, and the unequal man, are all thought to be Unjust and so manifestly the Just man will be, the man who acts according to law, and the equal man “The Just” then will be the lawful and the equal, and “the Unjust” the unlawful and the unequal. Well, since the Unjust man is also a grasping man, he will be so, of course, with respect to good things, but not of every kind, only those which are the subject-matter of good and bad fortune and which are in themselves always good but not always to the individual.[4] Yet men pray for and pursue these things: this they should not do but pray that things which are in the abstract good may be so also to them, and choose what is good for themselves.
