There is no reason to believe that any one of these types of religion is the only one adapted to promoting sound ethics in all individuals, nor that a similar culture can bring about uniformity in the near future, since the religion of a race corresponds to some extent to the inherent nature of the mind of its individuals. Up to a certain point, each type of religion has a distinct appeal to a certain temperament or type of mind. With increasing intelligence, it is probable that a religion tends to emphasize the interests of all rather than the benefits to be derived by one; such has been clearly the case in the history of the Christian religion. The diverse elements of retribution, damnation, "communion with God" and social service still exist, but in America the last-named one is yearly being more emphasized. Emphasis upon it is the marked characteristic of Jesus' teaching. With this rough sketch of religious ideas in mind, the part religion can play at the present day in advancing the eugenic interests of the race or species may be considered. Each religion can serve eugenics just as well as it can serve any other field of ethics, and by the very same devices. We shall run over our four types again and note what appeals eugenics can make to each one. 1. Reward and punishment in this life. Here the value of children, emotionally and economically, to their parents in their later life can be shown, and the dissatisfaction that is felt by the childless. The emotions may be reached (as they have been reached in past centuries) by the painting of Madonnas, the singing of lullabies, by the care of the baby sister, by the laurel wreath of the victorious son, by the great choruses of white-robed girls, by the happiness of the bride, and by the sentiment of the home. Here are some of the noblest subjects for the arts, which in the past have unconsciously served eugenics well. In a less emotional way, a deep desire for that "terrestrial immortality" involved in posterity should be fostered. The doctrine of the continuity of germ-plasm might play a large part in religion. It should at least be brought home to everyone at some point in his education. Man should have a much stronger feeling of identity with his forebears and his progeny. Is it not a loss to Christians that they have so much less of this feeling than the Chinese? It may be urged in opposition that such conceptions are dangerously static and have thereby harmed China. But that can be avoided by shifting the balance a little from progenitors to posterity. If people should live more in their children than they now do, they would be not only anxious to give them a sound heredity, but all the more eager to improve the conditions of their children's environment by modifying their own.
