Christian’s teaching, it could hardly have survived so long. We are told that it is now dead, but should it ever be revived we may well believe that this is the aspect by which it will be commended. It is a significant fact that at the two spiritual sources of our world, Jesus and Plato, we find the assertion of the principle of eugenics, in one implicitly, in the other explicitly. Jules de Gaultier was not concerned to put forward an aristocratic conception of his æsthetic doctrine, and, as we have seen, he remained on the threshold of eugenics. He was content to suggest, though with no positive assurance, a more democratic conception. He had, indeed, one may divine, a predilection for that middle class which has furnished so vast a number of the supreme figures in art and thought; by producing a class of people dispensed from tasks of utility, he had pointed out, “a society creates for itself an organ fitted for the higher life and bears witness that it has passed beyond the merely biological stage to reach the human stage.” But the middle class is not indispensable, and if it is doomed Gaultier saw ways of replacing it.[158] Especially we may seek to ensure that, in every social group, the individual task of utilitarian work shall be so limited that the worker is enabled to gain a leisure sufficiently ample to devote, if he has the aptitude, to works of intellect or art. He would agree with Otto Braun, the inspired youth who was slain in the Great War, that if we desire the enablement of the people “the eight-hours day becomes nothing less than the most imperative demand of culture.” It is in this direction, it may well be, that social evolution is moving, however its complete realisation may, by temporary causes, from time to time be impeded. The insistent demand for increased wages and diminished hours of work has not been inspired by the desire to raise the level of culture in the social environment, or to inaugurate any æsthetic revolution, yet, by “the law of irony” which so often controls the realisation of things, that is the result which may be achieved. The new leisure conferred on the worker may be transformed into spiritual activity, and the liberated utilitarian energy into æsthetic energy. The road would thus be opened for a new human adventure, of anxious interest, which the future alone can reveal. We cannot be sure that this transformation will take place. We cannot be sure, indeed, that it is possible for it to take place unless the general quality of the population in whom so fine a process must be effected is raised by a more rigid eugenic process than there is yet any real determination among us to exert. Men still bow down before the fetish of mere quantity in population, and that worship may be their undoing. Giant social organisms, like the giant animal species of early times, may be destined to disappear suddenly when they have attained their extreme expansion.
