Disobedience to custom evokes public indignation. In the lower stages of civilisation, especially, custom is a tyrant who binds man in iron fetters, and who threatens the transgressor, not only with general disgrace, but often with bodily suffering. “To believe that man in a savage state is endowed with freedom either of thought or action,” says Sir G. Grey, “is erroneous in the highest degree”;[31] and this statement is corroborated by an array of facts from all quarters of the savage world.[32] Now, as the rule of custom is a moral rule, the indignation aroused by its transgression is naturally a moral emotion. Moreover, where all the duties incumbent on a man are expressed in the customs of the society to which he belongs, it is obvious that the characteristics of moral indignation are to be sought for in its connection with custom. The most salient feature of custom is its generality. Its transgression calls forth public indignation; hence the flavour of generality which characterises moral disapproval. Custom is fixed once for all, and takes no notice of the preferences of individuals. By recognising the validity of a custom, I implicitly admit that the custom is equally binding for me and for you and for all the other members of the society. This involves disinterestedness; I admit that a breach of the custom is equally wrong whether I myself am immediately concerned in the act or not. It also involves apparent impartiality; I assume that my condemnation of the act is independent of the relationship in which the parties concerned in it stand to me personally, or, at least, I am not aware that my condemnation is influenced by any such relationship. And this holds good whatever be the origin of the custom. Though customs are very frequently rooted in public sympathetic resentment or in public disinterested aversions, they may have a selfish and partial origin as well. At first the leading men of the society may have prohibited certain acts because they found them disadvantageous to themselves, or to those with whom they particularly sympathised. Where custom is an oppressor of women, this oppression may certainly be traced back to the selfishness of men. Where custom sanctions slavery, it is certainly not impartial to the slaves. Yet in the one case as in the other, I assume custom to be in the right, irrespectively of my own station, and I even expect the women and slaves themselves to be of the same opinion. Such an expectation is by no means a chimera. Under normal social conditions, largely owing to men’s tendency to share sympathetically the resentment of their superiors, the customs of a society are willingly submitted to, and recognised as right, by the large majority of its members, whatever may be their station. Among the Rejangs of Sumatra, says Marsden, “a man without property, family, or connections, never, in the partiality of self-love, considers his own life as being of equal value with that of a man of substance.”[33] However selfish, however partial a certain rule may be, it becomes a true custom, a moral rule, as soon as the selfishness or the partiality of its makers is lost sight of.

It will perhaps be argued that, by deriving the characteristics of moral indignation from its connection with custom, we implicitly contradict our initial assumption that moral emotions lie at the bottom of all moral judgments. But it is not so. Custom is a moral rule only on account of the indignation called forth by its transgression. In its ethical aspect it is nothing but a generalisation of emotional tendencies, applied to certain modes of conduct, and transmitted from generation to generation. Public indignation lies at the bottom of it. In its capacity of a rule of duty, custom, mos, is derived from the emotion to which it gave its name.

As public indignation is the prototype of moral disapproval, so public approval, expressed in public praise, is the prototype of moral approval. Like public indignation, public approval is characterised by a flavour of generality, by disinterestedness, by apparent impartiality. But of these two emotions public indignation, being at the root of custom and leading to the infliction of punishment, is by far the more impressive. Hence it is not surprising that the term “moral” is etymologically connected with mos, which always implies the existence of a social rule the transgression of which evokes public indignation. Only by analogy it has come to be applied to the emotion of approval as well.

Though taking their place in the system of human emotions as public emotions felt by the society at large, moral disapproval and approval have not always remained inseparably connected with the feelings of any special society. The unanimity of opinion which originally characterised the members of the same social unit was disturbed by its advancement in civilisation. Individuals arose who found fault with the moral ideas prevalent in the community to which they belonged, criticising those ideas on the basis of their own individual feelings. Such rebels are certainly no less justified in speaking in the name of morality true and proper, than is society itself. The emotions from which their opposition against public opinion springs may be, in nature, exactly similar to the approval or disapproval felt by the society at large, though they are called forth by different facts or, otherwise, differ from these emotions in degree. They may present the same disinterestedness and apparent impartiality—indeed, dissent from the established moral ideas largely rises from the conviction that the apparent impartiality of public feelings is an illusion. As will be seen, the evolution of the moral consciousness involves a progress in impartiality and justice; it tends towards an equalisation of rights, towards an expansion of the circle within which the same moral rules are held applicable; and this process is in no small degree effected by the efforts made by high-minded individuals to raise public opinion to their own standard of right. Nay, as we have already noticed, individual moral feelings do not even lack that flavour of generality which characterises the resentment and approval felt unanimously by a body of men. Though, perhaps, persecuted by his own people as an outcast, the moral dissenter does not regard himself as the advocate of a mere private opinion.[34] Even when standing alone, he feels that his conviction is shared at least by an ideal society, by all those who see the matter as clearly as he does himself, and who are animated with equally wide sympathies, an equally broad sense of justice. Thus the moral emotions remain to the last public emotions—if not in reality, then as an ideal.
