The moralists of last century sometimes divided the field of ethics by assigning to man three grades or kinds of duty: duties to himself, duties to society, and duties to God. For the distinction there is a good deal to be said: there are also faults to be found with it. It may be said, amongst other things, that to speak of duties to self is a metaphorical way of talking, and that God lies out of the range of human duty altogether, except in so far as religious service forms a part of social obligation. It may be urged that man is essentially a social being, and that it is only in his relations to other such beings that his morality can find a sphere. The sphere of morality, according to Dr. Bain, embraces whatever “society has seen fit to enforce with all the rigour of positive inflictions. Positive good deeds and self-sacrifice ... transcend the region of morality proper and occupy a sphere of their own(62).” And there is little doubt that this restriction is in accordance with a main current of usage. It may even be said that there are tendencies towards a narrower usage still, which would restrict the term to questions affecting the relations of the sexes. But, without going so far, we may accept the standpoint which finds in the phrase “popular or social” sanction, as equivalent to the moral sanction, a description of the average level of common opinion on the topic. The morality of an age or country thus denotes, first, the average requirement in act and behaviour imposed by general consent on the members of a community, and secondly, the average performance of the members in response to these requirements. Generally speaking the two will be pretty much the same. If the society is in a state of equilibrium, there will be a palpable agreement between what all severally expect and what all severally perform. On the other hand, as no society is ever in complete equilibrium, this harmony will never be perfect and may often be widely departed from. In what is called a single community, if it reach a considerable bulk, there are (in other words) often a number of minor societies, more or less thwarting and modifying each other; and different observers, who belong in the main to one or other of these subordinate groups, may elicit from the facts before them a somewhat different social code, and a different grade of social observance. Still, with whatever diversity of detail, the important feature of such social ethics is that the stress is laid on the performance of certain acts, in accordance with the organisation of society. So long as the required compliance is given, public opinion is satisfied, and morality has got its due.
