I
THE PRECIOUS TEN

According to our religious belief, the last best work of God is the human race. According to the observation of biologists, the highest product of evolution is the human race. According to our own natural inner conviction, this twofold testimony is quite acceptable: we are the first class.

Whatever our merits when compared with lower species, however, we vary conspicuously when compared with one another. Humanity is superior to equinity, felinity, caninity; but there are degrees of humanness.

Between existing nations there is marked difference in the qualities we call human; and history shows us a long line of advance in these qualities in the same nation. The human race is still in the making, is by no means done; and, however noble it is to be human, it will be nobler to be humaner. As conscious beings, able to modify our own acts, we have power to improve the species, to promote the development of the human race. This brings us to the children. Individuals may improve more or less at any time, though most largely and easily in youth; but race improvement must be made in youth, to be transmitted. The real progress of man is born in him.

If you were buying babies, investing in young human stock as you would in colts or calves, for the value of the beast, a sturdy English baby would be worth more than an equally vigorous young Fuegian. With the same training and care, you could develope higher faculties in the English specimen than in the Fuegian specimen, because it was better bred. The savage baby would excel in some points, but the qualities of the modern baby are those dominant to-day. Education can do much; but the body and brain the child is born with are all that you have to educate. The progress of humanity must be recorded in living flesh. Unless the child is a more advanced specimen than his father and mother, there is no racial improvement. Virtues we still strive for are not yet ours: it is the unconscious virtues we are born with that measure the rise of nations.

Our mechanical products in all their rich variety serve two purposes, – to show the measure of the brains that made them, and to help make better ones.

The printing-press, for instance, marked a century of ability; but its main value is to develope centuries of greater ability. Society secretes, as it were, this mass of material wherewith to nourish its countless young; and, as this material is so permanent and so mobile, it is proportionately more advantageous to our posterity than the careful preparation of some anxious insect for her swarm of progeny. Unless the creature is born better than his creators, they do not save him. He sinks back or is overcome by others, perhaps lingering decadent among the traces of lost arts, like degenerate nomad savages who wander among the ruins of ancestral temples. We see plenty of such cases, individually, showing this arrested social development, – from the eighteenth-century man, who is only a little behind his age and does not hinder us much, to the dragging masses of dull peasantry and crude savagery, which keep us back so seriously. This does not include the reversions and degenerates, the absolutely abortive members of society; but merely its raw stock, that heavy proportion of the people who are not bred up to the standard of the age. To such we may apply every advantage of education, every facile convenience of the latest day; and, though these things do help a little, we have still the slow-minded mass, whose limited range of faculties acts as a steady check on the success of our best intellects. The surest, quickest way to improve humanity is to improve the stock, the people themselves; and all experience shows that the time to improve people is while they are young. As in a growing cornstalk the height is to be measured from joint to joint, not counting the length of its long, down-flowing leaves, so in our line of ascent the height is to be measured from birth to birth, not counting the further development of the parent after the child is born.

The continued life of the parent counts in other ways, as it contributes to social service; and, in especial, as it reacts to promote the further growth of the young. But the best service to society and the child is in the progress made by the individual before parentage, for that progress is born into the race. Between birth and birth is the race bred upward. Suppose we wish to improve a race of low savages, and we carefully select the parents, subjecting them to the most elaborate educational influences, till they are all dead. Then we return, and take a fresh set of parents to place under these advantageous conditions, leaving the children always to grow up in untouched savagery. This might be done for many generations, and we should always have the same kind of savages to labour with, what improvement was made being buried with each set of parents. Now, on the other hand, let us take the children of the tribe, subject them to the most advantageous conditions, and, when they become parents, discontinue our efforts on that generation and begin on the next. What gain was made in this case would be incorporated in the stock; we should have gradually improving relays of children.

So far as environment is to really develope the race, that development must be made before the birth of the next generation.

If a young man and woman are clean, healthy, vigorous, and virtuous before parenthood, they may become dirty, sickly, weak, and wicked afterward with far less ill effect to the race than if they were sick and vicious before their children were born, and thereafter became stalwart saints. The sowing of wild oats would be far less harmful if sowed in the autumn instead of in the spring.

Human beings are said to have a longer period of immaturity than other animals; but it is not prolonged childhood which distinguishes us so much as prolonged parenthood. In early forms of life the parent promptly dies after having reproduced the species. He is of no further use to the race, and therefore his life is discontinued. In the evolution of species, as the parent becomes more and more able to benefit the young, he is retained longer in office; and in humanity, as it developes, we see an increasing prolongation of parental usefulness. The reactive value of the adult upon the young is very great, covering our whole range of conscious education; but the real worth of that education is in its effects on the young before they become parents, that the training and improvement may become ours by birth, an inbred racial progress.

It may be well here to consider the objections raised by the Weissman theory that "acquired traits are not transmissible." To those who believe this it seems useless to try to improve a race by development of the young with a view to transmission. They hold that the child inherits a certain group of faculties, differing from the parents perhaps through the "tendency to vary," and that, although you may improve the individual indefinitely through education, that improvement is not transmissible to his offspring. The original faculties may be transmitted, but not the individual modification. Thus they would hold that, if two brothers inherited the same kind and amount of brain power, and one brother was submitted to the finest educational environment, while the other was entirely neglected, yet the children of the two brothers would inherit the same amount of brain development: the training and exercise which so visibly improved the brain of the educated brother would be lost to his children.

Or, if two brothers inherited the same physical constitution, and one developed and improved it by judicious care and exercise, while the other wasted strength and contracted disease, the children of either would inherit the original constitutional tendencies of the parent, unaffected by that parent's previous career.

This would mean that the whole tremendous march of race-modification has been made under no other influence than the tendency to vary, and that individual modification in no way affects the race.

Successive generations of individuals may be affected by the cumulative pressure of progress, but not the race itself. Under this view the Fuegian baby would be as valuable an investment as the English baby, unless, indeed, successive and singularly connected tendencies to vary had worked long upon the English stock and peculiarly neglected the Fuegian. In proof of this claim that "acquired traits are not transmissible," an overwhelming series of experiments are presented, as wherein many consecutive generations of peaceful guinea pigs are mutilated in precisely the same way, and, lo! the last guinea pig is born as four-legged and symmetrically-featured as the first.

If it had been so arranged that the crippled guinea pigs obtained some advantage because of their injuries, they might have thus become "fittest"; and the "tendency to vary" would perhaps have launched out a cripple somewhere, and so evolved a triumphant line of three-legged guinea pigs.

But, as proven by these carefully conducted scientific experiments, it does not "modify the species" at all to cut off its legs, – not in a score of generations. It modifies the immediate pig, of course, and is doubtless unpleasant to him; but the effect is lost with his death.

It has always seemed to me that there was a large difference between a mutilation and an acquired trait. An acquired trait is something that one uses and developes, not something one has lost.

The children of a soldier are supposed to inherit something of his courage and his habit of obedience, not his wooden leg.

The dwindled feet of the Chinese ladies are not transmitted; but the Chinese habits are. The individual is most modified by what he does, not by what is done to him; and so is the race.

Let a new experiment be performed on the long-suffering guinea pig. Take two flourishing pair of the same family (fortunately, the tendency to vary appears to be but slight in guinea pigs, so there is not serious trouble from that source), and let one pair of guinea pigs be lodged in a small but comfortable cage, and fed and fed and fed, – not to excess, but so as to supply all guinea-piggian desires as soon as felt, – them and their descendants in their unnumbered generations. Let the other pair be started on a long, slow, cautious, delicate but inexorable system of exercise, not exercise involving any advantage, with careful mating of the most lively, – for this would be claimed as showing only the "tendency to vary" and "survival of the fittest," – but exercise forced upon the unwilling piggies to no profit whatever.

A wheel, such as mitigates the captivity of the nimble squirrel, should be applied to these reluctant victims; a well-selected, stimulating diet given at slowly increasing intervals; and the physical inequalities of their abode become greater, so that the unhappy subjects of scientific research would find themselves skipping ever faster and farther from day to day.

If, after many generations of such training, the descendants of these cultivated guinea pigs could not outrun the descendants of the plump and puffy cage-fed pair, the Weissman theory would be more strongly re-enforced than by all the evidence of his suffering cripples. Meanwhile the parent and teacher in general is not greatly concerned about theories of pan-genesis or germ-plasm. He knows that, "as the twig is bent, the tree's inclined," and that, if the fathers have eaten sour grapes, the children's teeth are pretty certain to be set on edge.
