This line of reflection therefore has landed us in a real perplexity respecting the department of duty which we are at present examining. Justice is something that we conceive to be intrinsically capable of perfectly definite determination: a scrupulously just man, we think, must be very exact and precise in his conduct. But when we consider that part of Justice which consists in satisfying such natural and customary claims as arise independently of contract, it seems impossible to estimate these claims with any exactness. The attempt to map out the region of Justice reveals to us a sort of margin or dim borderland, tenanted by expectations which are not quite claims and with regard to which we do not feel sure whether Justice does or does not require us to satisfy them. For the ordinary actions of men proceed on the expectation that the future will resemble the past: hence it seems natural to expect that any particular man will do as others do in similar circumstances, and, still more, that he will continue to do whatever he has hitherto been in the habit of doing; accordingly his fellow-men are inclined to think themselves wronged by his suddenly omitting any customary or habitual act, if the omission causes them loss or inconvenience.[209] On the other hand, if a man has given no pledge to maintain a custom or habit, it seems hard that he should be bound by the unwarranted expectations of others. In this perplexity, common sense often appears to decide differently cases similar in all respects, except in the quantity of disappointment caused by the change. For instance, if a poor man were to leave one tradesman and deal with another because the first had turned Quaker, we should hardly call it an act of injustice, however unreasonable we might think it: but if a rich country gentleman were to act similarly towards a poor neighbour, many persons would say that it was unjust persecution. The difficulty just pointed out extends equally to the duties of kindness--even to the specially stringent and sacred duties of the domestic affections and gratitude--discussed in the previous chapter. We cannot get any new principle for settling any conflict that may present itself among such duties, by asking ‘what Justice requires of us’: the application of the notion of Justice only leads us to view the problem in a new aspect as a question of the right _distribution_ of kind services--it does not help us to solve it. Had we clear and precise intuitive principles for determining the claims (_e.g._) of parents on children, children on parents, benefactors on the recipients of their benefits, we might say exactly at what point or to what extent the satisfaction of one of these claims ought in justice to be postponed to the satisfaction of another, or to any worthy aim of a different kind: but I know no method of determining a problem of this kind which is not either implicitly utilitarian, or arbitrarily dogmatic, and unsupported by Common Sense.
