Here then is a fact that all positive morality presupposes. It presupposes that life by its very nature contains the possibility in it of some one kind of happiness, which is open to all men, and which is better than all others. The proudest, the serenest, the most successful life of vice, must be miserable when compared with the most painful life of virtue, and miserable in a very high degree; for morality is momentous exactly in proportion to the interval between the things to be gained and escaped by it. Now is this “happiness” a reality or is it a myth? That is the great question. Can human life, cut off utterly from every hope beyond itself — can human life supply it? If it cannot, then evidently there can be no morality without religion. But perhaps it can. Perhaps life has greater capacities than we have hitherto given it credit for. Perhaps this happiness may be really close at hand for each of us, and we have only overlooked it hitherto because it was too directly before our eyes. At all events, wherever it is, let it be pointed out to us. It is useless, as we have seen, if not generally presentable. To those who most need it, it is useless until presented. Indeed, until it is presented we are but acting on the maxim of its advocates by refusing to believe in its existence. ‘No simplicity of mind,’ says Professor Clifford, ‘no obscurity of station, can escape the universal duty of questioning all that we believe.’
