Race or breed was a moment ago described as a factor in human nature. But to break up human nature into factors is something that we can do, or try to do, in thought only. In practice we can never succeed in doing anything of the kind. A machine such as a watch we can take to bits and then put together again. Even a chemical compound such as water we can resolve into oxygen and hydrogen and then reproduce out of its elements. But to dissect a living thing is to kill it once and for all. Life, as was said in the first chapter, is something unique, with the unique property of being able to evolve. As life evolves, that is to say changes, by being handed on from certain forms to certain other forms, a partial rigidity marks the process together with a partial plasticity. There is a stiffening, so to speak, that keeps the life-force up to a point true to its old direction; though, short of that limit, it is free to take a new line of its own. Race, then, stands for the stiffening in the evolutionary process. Just up to what point it goes in any given case we probably can never quite tell. Yet, if we could think our way anywhere near to that point in regard to man, I doubt not that we should eventually succeed in forging a fresh instrument for controlling the destinies of our species, an instrument perhaps more powerful than education itself--I mean, eugenics, the art of improving the human breed.
The first care of the male stickleback, when he has acquired his courting suit, is to build a suitable home for his future wives and children. So he picks up stems of grass and water-weeds with his mouth, and weaves them deftly into a compact nest as perfect as a bird's, though some what different in shape and pattern, it rather resembles a barrel, open at both ends, as though the bottom were knocked out: this form is rendered necessary because the eggs, when laid, have to be constantly aerated by passing a current of water through the nest as I shall describe hereafter. No. 1 shows us such a nest when completed, with the female stickleback loitering about undecided as to whether or not she shall plunge and enter it. You will observe that the fabric is woven round a fixed support of some waving water-weeds; but the cunning little architect does not trust in this matter to his textile skill alone; he cements the straws and other materials together with a gummy mortar of mucous threads secreted for the purpose by his internal organs.
Any one who will look around upon the families of his acquaintance will observe that family characteristics and resemblances prevail not only in respect to stature, form, expression of countenance, and other outward and bodily tokens, but also in regard to the constitutional temperaments and capacities of the soul. Sometimes we find a group in which high intellectual powers and great energy of action prevail for many successive generations, and in all the branches into which the original stock divides; in other cases, the hereditary tendency is to gentleness and harmlessness of character, with a full development of all the feelings and sensibilities of the soul. Others, again, exhibit congenital tendencies to great physical strength and hardihood, and to powers of muscular exertion and endurance. These differences, notwithstanding all the exceptions and irregularities connected with them, are obviously, where they exist, deeply seated and permanent. They depend very slightly upon any mere external causes. They have, on the contrary, their foundation in some hidden principles connected with the origin of life, and with the mode of its transmission from parent to offspring, which the researches of philosophers have never yet been able to explore.
