Then followed a period of rapid increase in our knowledge of heredity in animals and plants and in 1901 Galton returned again to the subject, this time in a more direct and elaborate way, and his Huxley Lecture of that year before the Anthropological Institute was upon "The Possible Improvement of the Human Breed under the Existing Conditions of Law and Sentiment." This time he received a real hearing, partly on account of recent disclosures regarding the state of human society and its trends in Great Britain, chiefly because there was at last a real scientific basis for such a proposal. In this lecture, after declaring that the possibility of human race culture is no longer to be considered an academical or impractical problem, Galton proceeded to show that we have a sufficient biological knowledge of man to furnish a working basis. We know of man's variability and heredity—that some men are worth more than others in the community, and that individual traits are also family possessions. This he followed up with definite suggestions as to possible means of the "augmentation of favored stock."
The then recently organized Sociological Society of London took up the subject enthusiastically, and in 1904 and 1905 Galton was invited to deliver addresses before the Society upon this topic. In his first address he spoke upon "Eugenics: its Definition, Scope, and Aims." This proved to be a statement of the elementary principles of the subject—a sort of eugenic creed. Here Galton struck fire. The reading of his paper was followed by very extended discussion and criticism, and he received some enthusiastic support. A few of these enthusiastic supporters brought forth, on the spur of the moment, wonderful, visionary schemes for eugenic progress; much of the adverse criticism went wide of the mark; and, on the whole, Galton must have felt that at least he had demonstrated fully one need for which he had spoken, that of developing a race of able thinkers. Galton's second address before the same society the year following was partly directed at some of this hasty criticism and partly devoted to the setting forth of the possibly ultimate place of the ideals of race improvement in the conscience of the community, and to showing how the whole subject is fraught with "the greatest spiritual dignity and the utmost social importance."
The subject was now fairly launched. Magazine articles appeared on "The New National Patriotism," "Breeding Better Men," et cetera. Meanwhile the bio-sociologist settled down to work. And during the five years that have since passed an immense amount of knowledge has been gained, and a large number of excellent workers recruited. Interest in the subject is now general, and its importance recognized as vital. Karl Pearson, known as a good fighter, is Galton's "beak and claws," performing for him much the same kind of service that Huxley performed for Darwin nearly fifty years ago. Galton himself has established a Eugenics Laboratory under the direction of Professor Pearson in the Biometric Laboratory of the University of London and has endowed a Research Fellowship and Research Scholarships. This laboratory is publishing a series of Memoirs and a series of Lectures upon eugenic topics. The University of London is publishing, with the assistance of the Drapers' Company, a series of "Studies in National Deterioration." A periodical, The Eugenics Review, is established and appearing regularly. A Eugenics Education Society has been founded to popularize and disseminate the technical information contained in the memoirs and special papers. England remains the seat of greatest activity and interest, but much is being done now in this country. In America the subject is largely under the auspices of the American Breeders Association, which has organized an extremely efficient Committee on Eugenics with which a large number of biological and medical workers are coöperating. This committee has coöperated in the establishment of a Eugenics Record Office, at Cold Spring Harbor, under the direction of H. H. Laughlin. Relevant facts are beginning to pour in from many directions; eugenic ideals are being given practical expression, and the science is rapidly gaining headway.
It may be asked: "Well, what is it all about; are we as a nation not doing well—well enough?" Is it not true, as some have suggested, that this eugenic movement is but one more expression of England's temporary national hysteria transferred to this country? In answer to such queries let us state some of the conditions which have suggested to so many sober thinkers and observers that the time is arriving, has in fact arrived, when we must begin to think of the future of our communities and nations and of our race, rather than contentedly to read of and meditate upon the great achievements of our past, or to parade with self-satisfied air through our glass houses of Anglo-Saxon supremacy. Even were we unthreatened, were we amply holding our own, the mere fact of the possibility of a natural increase of human capacity would make it a practical subject of the utmost importance. We may be sure that somewhere a nation will avail itself of such a possibility as the increase of inherent native talent, physical, mental, moral, and will tend to become a strong and dominant people. Why should not we be that people?
It seems that the facts that lead us to think of the future in this matter are of two quite distinct classes. First, we have a great mass of data relative to the composition of our societies and to the changing character of our population, social data of deep significance when broadly viewed and thoughtfully considered. Second, there are certain biological considerations, which all apart from existing social conditions should warn us to be on the lookout. First let us review briefly some of the latter, some of those biological considerations which lead us to regard thoughtfully the problem of the future evolution of man and his societies.
As with other species of animals, each of us comes into the world equipped with a physical constitution and a few simple fundamental instincts. But unlike all other animals, the possession of these alone does not enable us to take and maintain our positions in the community life. Man's life to-day is subject to a great social heritage which, unlike his natural heritage, can be realized only as a result of his own activity and acquisition. Civilized man is the result of Nature plus Nurture. Civilization has been defined as "the sum of human contrivances which enable human beings to advance independently of heredity." The knowledge of fact, historic and scientific, of literature, of art, of custom, and manner, and all that goes to make up the culture and education which are the distinctive traits of our human lives—all this is no possession of ours when we make our first bow to society. Nor do these things become ours through a simple process of growth and development while we remain the passive subjects. All of these things represent the active individual acquirement of the racial accumulation of tradition and learning—what the biologist would call the results of modification. Our troubles begin when we realize that in the acquisition of this load each generation does not begin where the preceding left off, not at all—but we begin where our parents did. The first thing we do toward advancing our places in the world is to absorb what we can of the same kind of thing our forbears absorbed, learn over again their lessons, repeat their experiences; and then we proceed straightway to increase the difficulties for the next generation by writing more books, discovering more facts, making a little more history, and so it goes: the load of tradition increases with every successive generation, and so it has gone since the beginning of man's civilization. It is declared that the modern schoolboy knows more than did Aristotle. We cannot resist the inquiry, Has the modern schoolboy better native ability than had Aristotle? Here is the whole point of this matter; are we any better endowed mentally now that the amount to be mentally absorbed and accomplished is so many times greater? Has our capacity for mental accumulation kept pace with the amount to be accumulated, and with the necessity for such accumulation as a fitting for human life of the civilized variety?
Madison Bentley has recently put it nicely in this way. Does talent grow with knowledge? "May we not suppose that the men and women of some distant glacial age, who dwelt upon the ice, wore the skin of the seal, and ate raw fish, had as much brain and as generous a measure of talent as have their remote descendants who wear sealskins, and eat ices and caviar?" He continues that we have little or nothing to show that the hereditary or innate growth of the mind has kept pace with the growing social heritage; that as regards mental endowment we begin where our distant ancestors began. The chief difference between us and them is that we proceed at once to burden ourselves with information and obligation which for them did not exist. To compass our languages, sciences, histories, arts, the complicated social, political, moral régime, we are supplied with virtually the same minds that primitive man used for his primitive needs. Is it any wonder, he asks, that "education" is the central problem for our or any other advanced civilization?
The biologist asks whether it is not high time to look beyond this artificial bolster of education, to the possibility of actual improvement of the innate mental abilities of man. The student of heredity and evolution looking at this problem has two contributions to make. First, if the mental capabilities of the present race are too limited, increase them; if our minds are too weak to carry the burdens which now must be carried, do not give up the task—strengthen the racial mind. Second, if we should seem to be in danger of developing a stock which is well fitted and able to carry the load of mental acquirement and to push on intellectually, but which is at the same time physically deficient, weak, or sterile, or susceptible to disease, do not let the intellectual capabilities diminish, but build up the physical constitution to a higher supporting level. These are not idle suggestions nor whimsical schemes. The biologist makes them knowing that these things are possible; not only possible, they must be accomplished. We are foolishly building our civilization in the form of an inverted pyramid of individually acquired characteristics. This structure can be made stable only by supplying a broader basis of innate ability which can safely carry the load. This is the first biological warning to sociology.
The second warning we may put in the form in which Ray Lankester in his "Kingdom of Man" has recently presented it so strikingly and which we may abstract freely and with some interpolation. "In Nature's struggle for existence, death ... is the fate of the vanquished, while the only reward to the victors ... is the permission to reproduce their kind—to carry on by heredity to another generation, the specific qualities by which they triumphed." The origin of man, partly, at any rate, by such a process of natural selection, is one chapter in his history. Another begins with the development of his mental qualities, which are of such unprecedented power in Nature. These qualities so dominate all else in his "living" activities that they largely cut him off from the general operations of natural selection. Perhaps the only direction in which natural selection is the chiefly operative factor in human evolution to-day is in the development of immunity from infectious disease. Just as man is a new departure in the unfolding scheme of the world, so his presence and characteristics lead to new methods of evolution, of survival, and the like. Knowledge, reason, self-consciousness, will, are new processes in Nature, and it is these which have largely determined the direction of man's history. Nature's discipline of death is more or less successfully resisted by the will of man. Man is Nature's Rebel. "Where Nature says 'Die'! Man says 'I will live.'" By his wits and his will man has overcome many of Nature's bounds and difficulties without changing, as other organisms would, his innate characteristics. Not only this but man has obtained control of his surroundings and at every step of his development he has receded farther from the rule of Nature. Now "he has advanced so far and become so unfitted to the earlier rule, that to suppose that Man can 'return to Nature' is as unreasonable as to suppose that an adult animal can return to its mother's womb."
But at present man puts into operation no real substitute for natural selection. "The standard raised by the rebel man is not that of fitness to the conditions proffered by extra-human Nature, but is one of ideal comfort, prosperity, and conscious joy of life—imposed by the will of man and involving a control, and in important respects a subversion, of what were Nature's methods of dealing with life before she had produced her insurgent son." Progress in the control of Nature has been going on with enormous rapidity during the last two centuries particularly—the "nature searchers" have placed almost limitless power in the hands of men. And yet the builders of society and governments and nations have failed to profit by this increase in natural knowledge. In our social and national organization we remain fixed in the old paths of ignorance. Lankester says: "I speak for those who would urge the conscious and deliberate assumption of his kingdom by Man—not as a matter of markets and of increased opportunity for the cosmopolitan dealers in finance—but as an absolute duty, the fulfillment of Man's destiny." The purpose of his essay is "to point out that civilized man has proceeded so far in his interference with extra-human Nature, has produced for himself and for the living organisms associated with him such a special state of things, by his rebellion against natural selection and his defiance of pre-human dispositions, that he must either go on and acquire firmer control of the conditions, or perish miserably by the vengeance certain to fall on the half-hearted meddler in great affairs." Man is a fighting rebel who at every forward step lays himself open to the liabilities of greater penalties should his attack prove unsuccessful. Moreover, while emancipating himself from the destructive and progressive methods of Nature, man has accumulated a new series of dangers and difficulties with which he must incessantly contend and which he must finally control. Man has taken a tremendous step—created desperate conditions by the exercise of his will—further control is essential in order that he should escape from final misery and destruction.
