When the social sanction operates, not through society generally, but through particular sections of society, it may be called a Law of Honour, a term which originated in the usages of Chivalry. In a complex and civilized form of society, such as our own, there may be many such laws of honour, and the same individual may be subject to several of them. Thus each profession, the army, the navy, the clerical, the legal, the medical, the artistic, the dramatic profession, has its own peculiar code of honour or rules of professional etiquette, which its members can only infringe on pain of ostracism, or, at least, of loss of professional reputation. The same is the case with trades, and is specially exemplified in the instance of trades-unions, or, their mediaeval prototypes, the guilds. A college or a school, again, has its own rules and traditions, which the tutor or undergraduate, the master or boy, can often only violate at his extreme peril. Almost every club, institution, and society affords another instance in point. The class of 'gentlemen,' too, that is to say, speaking roughly, the upper and upper middle ranks of society, claim to have a code of honour of their own, superior to that of the ordinary citizen. A breach of this code is called 'ungentlemanly' rather than wrong or immoral or unjust or unkind. So far as this code insists on courtesy of demeanour and delicacy of feeling and conduct, it is a valuable complement to the ordinary rules of morality, though, so far as it fulfils this function, it plainly ought not to be the exclusive possession of one class, but ought to be communicated, by means of example and education, to the classes who are now supposed to be bereft of it. There are points in this code, however, such as that the payment of 'debts of honour' should take precedence of that of tradesmen's bills, and that less courtesy is due to persons in an inferior station than to those in our own, which at least merit re-consideration. It may, indeed, be said of all these laws or codes of honour, that, though they have probably, on the whole, a salutary effect in maintaining a high standard of conduct in the various bodies or classes where they obtain, they require to be constantly watched, lest they should become capricious or tyrannical, and specially lest they should conflict with the wider interests of society or the deeper instincts of morality. It must not be forgotten that we are 'men' before we are 'gentlemen,' and that no claims of any profession, institution, or class can replace or supplant those of humanity and citizenship.
