It is along such lines as these that our knowledge of the eugenic conditions of life will grow adequate and precise enough to form an effective guide to social conduct. Nature, and a due attention to laws of heredity in life, will then rank in equal honour to our eyes with nurture or that attention to the environmental conditions of life which we already regard as so important. A regard to nurture has led us to spend the greatest care on the preservation not only of the fit but the unfit, while meantime it has wisely suggested to us the desirability of segregating or even of sterilising the unfit. But the study of Nature leads us further and, as Galton said, "Eugenics rests on bringing no more individuals into the world than can be properly cared for, and these only of the best stocks." That is to say that the only instrument by which eugenics can be made practically effective in the modern world is birth-control.

It is not scientific research alone, nor even the wide popular diffusion of knowledge, that will suffice to bring eugenics and birth-control, singly or in their due combination, into the course of our daily lives. They need to be embodied in our instinctive impulses. Galton considered that eugenics must become a factor of religion and be regarded as a sacred and virile creed, while Ellen Key holds that the religions of the past must be superseded by a new religion which will be the awakening of the whole of humanity to a consciousness of the "holiness of generation." For my own part, I scarcely consider that either eugenics or birth-control can be regarded as properly a part of religion. Being of virtue and not of grace they belong more naturally to the sphere of morals. But here they certainly need to go far deeper than the mere intelligence of the mind can take them. They cannot become guides to conduct until their injunctions have been printed on the fleshy tablets of our hearts. The demands of the race must speak from within us, in the voice of conscience which we disobey at our peril. When that happens with regard to ascertained laws of racial well-being we may know that we are truly following, even though not in the letter, those great spirits, like Galton with his intellectual vision and Ellen Key with her inspired enthusiasm, who have pointed out new roads for the ennoblement of the race.

It may be well, before we go further, to look a little more closely into the suspicion and dislike which eugenics still arouses in many worthy old-fashioned people. To some extent that attitude is excused, not only by the mistakes which in a new and complex science must inevitably be made even by painstaking students, but also by the rash and extravagant proposals of irresponsible and eccentric persons claiming without warrant to speak in the name of eugenics. Two thousand years ago the wild excesses of some early Christians furnished an excuse for the ancient world to view Christianity with contempt, although the extreme absence of such excesses has furnished still better ground for the modern world to maintain the same view. To-day such a work as Le Haras Humain ("The Human Stud-farm") of Dr. Binet-Sanglé, putting forward proposals which, whether beneficial or not, will certainly find no one to carry them out, similarly furnishes an excuse to those who would reject eugenics altogether. Utopian schemes have their value; we should be able to find inspiration in the most modern of them, just as we still do in Plato's immortal Republic. But in this, as in other matters, we must exercise a little intelligence. We must not confuse the brilliant excursion of some solitary thinker with the well-grounded proposals of those who are concerned with the sober possibilities of actual life in our own time. People who are incapable of exercising a little shrewd commonsense in the affairs of life, and are in the habit of emptying out the baby with the bath, had better avoid touching the delicate problems connected with practical eugenics.

There is one prejudice already mentioned, due to lack of clear thinking, which deserves more special consideration because it is widespread among the socialistic democracy of several countries as well as among social reformers, and is directed alike against eugenics and birth-control. This prejudice is based on the ground that bad economic conditions and an unwholesome environment are the source of all social evils, and that a better distribution of wealth, or a vast scheme of social welfare, is the one thing necessary, when that is achieved all other things being added unto us, without any further trouble on our part. It is certainly impossible to over-rate the importance of the economic factor in society, or of a good environment. And it is true that eugenics alone, like birth-control alone, can effect little if the economic basis of society is unsound. But it is equally certain that the economic factor can never in itself suffice for fine living or even as a cure-all of social and racial diseases. Its value is not that it can effect these things but that it furnishes the favourable conditions for effecting them. He would be foolish indeed who went to the rich to find the example of good breeding and, as is well known, it is not with the rich that the future of the race lies. The fact is that under any economic system the responsible personal direction of the individual and the family remain equally necessary, and no progress is possible so long as the individual casts all responsibility away from himself on to the social group he forms part of. The social group, after all, is merely himself and the likes of himself. He is merely shifting the burden from his individual self to his collective self, and in so doing he loses more than he gains.

Thus there is always a sound core in that Individualism which has been preached so long and practised so energetically, especially in English-speaking lands, however great the abuse involved in its excesses. It is still in the name of Individualism that the most brilliant antagonists of eugenics and of birth-control are wont to direct their attacks. The counsel of self-control and foresight in procreation, the restriction necessary to purify and raise the standard of the race, seem to the narrow and short-sighted advocates of a great principle an unwarrantable violation of the sacred rights of their individual liberty. They have not yet grasped the elementary fact that the rights of the individual are the rights of all individuals, and that Individualism itself calls for a limitation of the freedom of the individual.

That is why even the most uncompromising Individualist must recognise an element of altruism, call it whatever name you will, Collectivism, Socialism, Communism, or merely the vague and long-suffering term, Democracy. One cannot assume Individualism for oneself unless one assumes it for the many. That is a great truth which goes to the heart of the whole complex problem of eugenics and birth-control. As Perrycoste has well argued,[22] biology is altogether against the narrow Individualism which seeks to oppose Collective Individualism. For if, in accordance with the most careful modern investigations, we recognise that heredity is supreme, that the qualities we have inherited from our ancestors count for more in our lives than anything we have acquired by our own personal efforts, then we have to admit that the capable man's wealth is more the community's property than his own, and, similarly, the incapable man's poverty is more the community's concern than his own. So that neither the capable nor the incapable are entitled to an unqualified power of freedom, and neither, likewise, are justly liable to be burdened by an unqualified responsibility. It is the duty of the community to draw on the powers of the fit and equally its duty to care for the unfit. In this way, Perrycoste, whose attitude is that of the Rationalist, is led by science to a conclusion which is that of the Christian. We are all members each of the other, and still more are we members of those who went before us. The generations preceding us have not died to themselves but live in us, and we, whom they produced, live in each other and in those who will come after us. The problems of eugenics and of birth-control affect us all. In the face of these problems it is the voice of Man that speaks: "Inasmuch as ye did it not unto the least of these my brethren, ye did it not unto me." However firmly we base ourselves on the principles of Individualism we are inevitably brought to the fundamental facts of eugenics which, if we fail to recognise, our Individualism becomes of no effect.

But it is the same with Socialism, or by whatever name we chose to call the Collectivist activities of the community in social reform. Socialism also brings us up against the hard rock of eugenic fact which, if we neglect it, will dash our most beautiful social construction to fragments. It is the more necessary to point this out since it is on the Socialist and Democratic side, much more frequently than on the Individualist side, that we find an indifferent or positively hostile attitude towards eugenic considerations. Put social conditions on a sound basis, the people on this side often say, let all receive an adequate economic return for their work and be recognised as having a claim for an adequate share in the products of society, and there is no need to worry about the race or about the need for birth-control, all will go well of itself. There is not the slightest ground for any such comfortable belief.

This has been well shown by Dr. Eden Paul, himself a Socialist and even in sympathy with the extreme Left.[23] After setting forth the present conditions, with our excessive elimination of higher types, and undue multiplication of lower types, the racial degeneration caused by the faulty and anti-selective working of the marriage system in modern capitalist society, so that in our existing civilisation unconscious natural selection has largely ceased to work towards the improvement of the human breed, he proceeds to consider the possible remedies. The frequent impatience of the Socialist, and Social Reformers generally, with eugenic proposals has a certain degree of justification in the fact that many evils thoughtlessly attributed to inferiority of stock are really due to bad environment. But when the environment has been so far improved that all defects due to its badness are removed, we shall be face to face, without possibility of doubt, with bad inheritance as the sole remaining factor in the production of inefficient and anti-social members of the community. A socialist community must recognise the right to work and to maintenance of all its members, Eden Paul points out, but, he adds, a community which allowed this right to all defectives without imposing any restrictions in their perpetuation of themselves would deserve all the evils that would fall upon it. It is quite clear how intolerable the burden of these evils would be. A State that provided an adequate subsistence for all alike, the inefficient as well as the efficient, would encourage a racial degeneration, from excessive multiplication of the unfit, far more dangerous even than that of to-day.[24] Ability to earn the minimum wage, Eden Paul argues in agreement with H.G. Wells, must be the condition of the right to become a parent. "Unless the socialist is a eugenist as well, the socialist state will speedily perish from racial degradation."
