§ 2. Perhaps we shall find it easier to answer this question, if we examine the notion of Justice as applied to that part of private conduct which lies beyond the sphere of law. Here, again, we may observe that the notion of Justice always involves allotment of something considered as advantageous or disadvantageous: whether it be money or other material means of happiness; or praise, or affection, or other immaterial good, or some merited pain or loss. Hence I should answer the question raised in the preceding chapter (§ 3), as to the classification of the duties there discussed under the heads of Justice and Benevolence respectively, by saying that the fulfilment of any duty of the affections, considered by itself, does not exemplify Justice: but that when we come to compare the obligations arising out of different affectionate relations, and to consider the right allotment of love and kind services, the notion of Justice becomes applicable. In order to arrange this allotment properly we have to inquire what is Just. What then do we mean by a just man in matters where law-observance does not enter? It is natural to reply that we mean an impartial man, one who seeks with equal care to satisfy all claims which he recognises as valid and does not let himself be unduly influenced by personal preferences. And this seems an adequate account of the virtue of justice so far as we consider it merely subjectively, and independently of the intellectual insight required for the realisation of objective justice in action: if we neglect to give due consideration to any claim which we regard as reasonable, our action cannot be just in intention. This definition suffices to exclude wilful injustice: but it is obvious that it does not give us a sufficient criterion of just acts, any more than the absence of arbitrary inequality was found to be a sufficient criterion of just laws.[208] We want to know what are reasonable claims. Well, of these the most important--apart from the claims discussed in the preceding chapter--seems to be that resulting from contract. This is to a certain extent enforced by law: but it is clear to us that a just man will keep engagements generally, even when there may be no legal penalty attached to their violation. The exact definition of this duty, and its commonly admitted qualifications, will be discussed in the next chapter: but of its general bindingness Common Sense has no doubt.
