Thus we have in the case of a community, be it the city or be it the state, an illustration of a sanction which is sufficient to compel observance of a rule without any question of the application of force. This kind of sanction may be of a highly compelling quality, and it often extends so far as to make the individual prefer the good of the community to his own. The development of many of our social institutions, of our hospitals, of our universities, and of other establishments of the kind, shows the extent to which it reaches and is powerful. But it has yet higher forms in which it approaches very nearly to the level of the obligation of conscience, although it is distinct from that form of obligation. I will try to make clear what I mean by illustrations. A man may be impelled to action of a high order by his sense of unity with the society to which he belongs, action of which, from the civic standpoint, all approve. What he does in such a case is natural to him, and is done without thought of reward or punishment; but it has reference to standards of conduct set up by society and accepted just because society has set them up. There is a poem by the late Sir Alfred Lyall which exemplifies the high level that may be reached in such conduct. The poem is called _Theology in Extremis_, and it describes the feelings of an Englishman who had been taken prisoner by Mahometan rebels in the Indian Mutiny. He is face to face with a cruel death. They offer him his life if he will repeat something from the Koran. If he complies, no one is likely ever to hear of it, and he will be free to return to England and to the woman he loves. Moreover, and here is the real point, he is not a believer in Christianity, so that it is no question of denying his Savior. What ought he to do? Deliverance is easy, and the relief and advantage would be unspeakably great. But he does not really hesitate, and every shadow of doubt disappears when he hears his fellow-prisoner, a half-caste, pattering eagerly the words demanded.
