But it is a conceivable and possible thing that this margin of futile struggling, pain and discomfort and death might be reduced to nearly nothing without checking physical and mental evolution, with indeed an acceleration of physical and mental evolution, by preventing the birth of those who would in the unrestricted interplay of natural forces be born to suffer and fail. The method of Nature "red in tooth and claw" is to degrade, thwart, torture, and kill the weakest and least adapted members of every species in existence in each generation, and so keep the specific average rising; the ideal of a scientific civilisation is to prevent those weaklings being born. There is no other way of evading Nature's punishment of sorrow. The struggle for life among the beasts and uncivilised men means misery and death for the inferior individuals, misery and death in order that they may not increase and multiply; in the civilised State it is now clearly possible to make the conditions of life tolerable for every living creature, provided the inferiors can be prevented from increasing and multiplying. But this latter condition must be respected. Instead of competing to escape death and wretchedness, we may compete to give birth and we may heap every sort of consolation prize upon the losers in that competition. The modern State tends to qualify inheritance, to insist upon education and nurture for children, to come in more and more in the interests of the future between father and child. It is taking over the responsibility of the general welfare of the children more and more, and as it does so, its right to decide which children it will shelter becomes more and more reasonable. How far will such conditions be prescribed? how far can they be prescribed in a Modern Utopia? Let us set aside at once all nonsense of the sort one hears in certain quarters about the human stud farm. [Footnote: See Mankind in the Making, Ch. II.] State breeding of the population was a reasonable proposal for Plato to make, in view of the biological knowledge of his time and the purely tentative nature of his metaphysics; but from anyone in the days after Darwin, it is preposterous. Yet we have it given to us as the most brilliant of modern discoveries by a certain school of sociological writers, who seem totally unable to grasp the modification of meaning "species" and "individual" have undergone in the last fifty years. They do not seem capable of the suspicion that the boundaries of species have vanished, and that individuality now carries with it the quality of the unique! To them individuals are still defective copies of a Platonic ideal of the species, and the purpose of breeding no more than an approximation to that perfection. Individuality is indeed a negligible difference to them, an impertinence, and the whole flow of modern biological ideas has washed over them in vain.
