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, etc. [28]

Exact investigation is now showing that feeble-mindedness is passed on from parent to child to an enormous extent. Some years ago Ashby, speaking from a large experience in the North of England, estimated that at least seventy-five per cent of feeble-minded children are born with an inherited tendency to mental defect. More precise investigation has since shown that this estimate was under the mark. Tredgold, who in England has most carefully studied the heredity of the feeble-minded, [29] found that in over eighty-two per cent cases there is a bad nervous inheritance. In a large number of cases the bad heredity was associated with alcoholism or consumption in the parentage, but only in a small proportion of cases (about seven per cent) was it probable that alcoholism and consumption alone, and usually combined, had sufficed to produce the defective condition of the children, while environmental conditions only produced mental defect in ten per cent cases. [30] Heredity is the chief cause of feeble-mindedness, and a normal child is never born of two feeble-minded parents. The very thorough investigation of the heredity of the feeble-minded which is now being carried on at the institution for their care at Vineland, New Jersey, shows even more decisive results. By making careful pedigrees of the families to which the inmates at Vineland belong it is seen that in a large proportion of cases feeble-mindedness is handed on from generation to generation, and is traceable through three generations, though it sometimes skips
