Three centuries ago an inspired monk set forth his ideal of an ennobled world in The City of the Sun. Campanella wrote that prophetic book in prison. But his spirit was unfettered, and his conception of human society, though in daring it outruns all the visions we may compare it with, is yet on the lines along which our civilization lies. In the City of the Sun not only was the nobility of work, even mechanical work—which Plato rejected and More was scarcely conscious of—for the first time recognized, but the supreme impulse of procreation was regarded as a sacred function, to be exercised in the light of scientific knowledge. It was a public rather than a private duty, because it concerned the interests of the race; only valorous and high-spirited men ought to procreate, and it was held that the father should bear the punishments inflicted on the son for faults due to his failure by defects in generation. [23] Moreover, while unions not for the end of procreation were in the City of the Sun left to the judgment of the individuals alone concerned, it was not so with unions for the end of procreation. These were arranged by the "great Master," a physician, aided by the chief matrons, and the public exercises of the youths and maidens, performed in a state of nakedness, were of assistance in enabling unions to be fittingly made. No eugenist under modern conditions of life proposes that unions should be arranged by a supreme medical public official, though he might possibly regard such an official, if divested of any compulsory powers, a kind of public trustee for the race, as a useful institution. But it is easy to see that the luminous conception of racial betterment which, since Galton rendered it practicable, is now inspiring social progress, was already burning brightly three centuries ago in the brain of this imprisoned Italian monk. Just as Thomas More has been called the father of modern Socialism, so Campanella may be said to be the prophet of modern Eugenics.
By "Eugenics" is meant the scientific study of all the agencies by which the human race may be improved, and the effort to give practical effect to those agencies by conscious and deliberate action in favour of better breeding. Even among savages eugenics may be said to exist, if only in the crude and unscientific practice of destroying feeble, deformed, and abnormal infants at birth. In civilized ages elaborate and more or less scientific attempts are made by breeders of animals to improve the stocks they breed, and their efforts have been crowned with much success. The study of the same methods in their bearing on man proceeded out of the Darwinian school of biology, and is especially associated with the great name of Sir Francis Galton, the cousin of Darwin. Galton first proposed to call this study "Stirpiculture." Under that name it inspired Noyes, the founder of the Oneida Community, with the impulse to carry it into practice with a thoroughness and daring—indeed a similarity of method—which caused Oneida almost to rival the City of the Sun. But the scheme of Noyes, excellent as in some respects it was as an experiment, outran both scientific knowledge and the spirit of the times. It was not countenanced by Galton, who never had any wish to offend general sentiment, but sought to win it over to his side, and before 1880 the Oneida Community was brought to an end in consequence of the antagonism it aroused. Galton continued to develop his conceptions slowly and cautiously, and in 1883, in his Inquiries into Human Faculty, he abandoned the term "Stirpiculture" and devised the term "Eugenics," which is now generally adopted to signify Good Breeding.
Galton was quite well aware that the improved breeding of men is a very different matter from the improved breeding of animals, requiring a different knowledge and a different method, so that the ridicule which has sometimes been ignorantly flung at Eugenics failed to touch him. It would be clearly undesirable to breed men, as animals are bred, for single points at the sacrifice of other points, even if we were in a position to breed men from outside. Human breeding must proceed from impulses that arise, voluntarily, in human brains and wills, and are carried out with a human sense of personal responsibility. Galton believed that the first need was the need of knowledge in these matters. He was not anxious to invoke legislation. [24] The compulsory presentation of certificates of health and good breeding as a preliminary to marriage forms no part of Eugenics, nor is compulsory sterilization a demand made by any reasonable eugenist. Certainly the custom of securing certificates of health and ability is excellent, not only as a preliminary to marriage, but as a general custom. Certainly, also, there are cases in which sterilization is desirable, if voluntarily accepted. [25] But neither certification nor sterilization should be compulsory. They only have their value if they are intelligent and deliberate, springing out of a widened and enlightened sense of personal responsibility to society and to the race.
Eugenics constitutes the link between the Social Reform of the past, painfully struggling to improve the conditions of life, and the Social Hygiene of the future, which is authorized to deal adequately with the conditions of life because it has its hands on the sources of life. On this plane we are able to concentrate our energies on the finer ends of life, because we may reasonably expect to be no longer hampered by the ever-increasing burdens which were placed upon us by the failure to control life; while the more we succeed in our efforts to purify and strengthen life, the more magnificent become the tasks we may reasonably hope to attempt and compass.
A problem which is often and justly cited as one to be settled by Eugenics is that presented by the existence among us of the large class of the feeble-minded. No doubt there are some who would regret the disappearance of the feeble-minded from our midst. The philosophies of the Bergsonian type, which to-day prevail so widely, place intuition above reason, and the "pure fool" has sometimes been enshrined and idolized. But we may remember that Eugenics can never prevent absolutely the occurrence of feeble-minded persons, even in the extreme degree of the imbecile and the idiot. [26] They come within the range of variation, by the same right as genius so comes. We cannot, it may be, prevent the occurrence of such persons, but we can prevent them from being the founders of families tending to resemble themselves. And in so doing, it will be agreed by most people, we shall be effecting a task of immense benefit to society and the race.
Feeble-mindedness is largely handed on by heredity. It was formerly supposed that idiocy and feeble-mindedness are mainly due to environmental conditions, to the drink, depravity, general disease, or lack of nutrition of the parents, and there is no doubt an element of truth in that view. But serious and frequent as are the results of bad environment and acquired disease in the parentage of the feeble-minded, they do not form the fundamental factor in the production of the feeble-minded. [27]
Feeble-mindedness is essentially a germinal variation, belonging to the same large class as all other biological variations, occurring, for the most part, in the first place spontaneously, but strongly tending to be inherited. It thus resembles congenital cataract, deaf-mutism, the susceptibility to tuberculous infection,
