to a man of merit who is connected with us, though we abstain from hurting him in every respect, if we do not exert ourselves to serve him and to place him in that situation in which the impartial spectator would be pleased to see him. The first sense of the word coincides with what Aristotle and the Schoolmen call commutative justice, and with what Grotius calls the justitia expletrix, which consists in abstaining from what is another’s, and in doing voluntarily whatever we can with propriety be forced to do. The second sense of the word coincides with what some have called distributive justice, l and with the justitia attributrix of Grotius, which consists in proper beneficence, in the becoming use of what is our own, and in the applying it to those purposes either of charity or generosity, to which it is most suitable, in our situation, that it should be applied.10 In this sense justice comprehends all the social virtues. There is yet another sense in which the word justice is sometimes taken, still more extensive than either of the former, though very much akin to the last; and which runs too, so far as I know, through all languages. It is in this last sense that we are said to be unjust, when we do not seem to value any particular object with that degree of esteem, or to pursue it with that degree of ardour which to the impartial spectator it may appear to deserve or to be naturally fitted for exciting. Thus we are said to do injustice to a poem or a picture, when we do not admire them enough, and we are said to do them more than justice when we admire them too much. In the same manner we are said to do injustice to ourselves when we appear not to give sufficient attention to any particular object of self-interest. In this last sense, what is called justice means the same thing with exact and perfect propriety of conduct and behaviour, and comprehends in it, not only the offices of both commutative and distributive justice, but of every other virtue, of prudence, of fortitude, of temperance. It is in this last sense that Plato evidently understands what he calls justice, and which, therefore, according to him, comprehends in it the perfection of every sort of virtue.
Such is the account given by Plato of the nature of virtue, or of that temper of mind which is the proper object of praise and approbation. It consists, according to him, in that state of mind in which every faculty confines itself within its proper sphere without encroaching upon that of any other, and performs its proper office with that precise degree of strength and vigour which belongs to it.11 His account, it is evident, coincides in every respect with what we have said above concerning the propriety of conduct.
II. Virtue, according to Aristotle,m consists in the habit of mediocrity according to right reason.12 Every particular virtue, according to him, lies in a kind of middle between two opposite vices, of which the one offends from being too much, the other from being too little affected by a particular species of objects. Thus the virtue of fortitude or courage lies in the middle between the opposite vices of cowardice and of presumptuous rashness, of which the one offends from being too much, and the other from being too little affected by the objects of fear. Thus too the virtue of frugality lies in a middle between avarice and profusion, of which the one consists in an excess, the other in a defect of the proper attention to the objects of self-interest. Magnanimity, in the same manner, lies in a middle between the excess of arrogance and the defect of pusillanimity, of which the one consists in too extravagant, the other in too weak a sentiment of our own worth and dignity.13 It is unnecessary to observe that this account of virtue corresponds too pretty exactly with what has been said above concerning the propriety and impropriety of conduct.
According to Aristotle,n indeed, virtue did not so much consist in those moderate and right affections, as in the habit of this moderation. In order to understand this, it is to be observed, that
