Human Social Value.—We have seen that, owing to traditional routine, the intellectual merit of a young man is unfortunately judged by the results of examinations. To succeed in these, a good memory and strong mental receptivity are all that is necessary. It follows from this that nonentities often attain the highest social positions, while originality, creative power, perseverance, honesty, responsibility and duty take a back place. I refer the reader to what I have said on the estimation of human value, especially in the Landerziehungsheime (Chapter XVI). They should be estimated according to their utility in practical social life, where the qualities of will and creative imagination play a more considerable part than memory and rapidity in assimilating the ideas of others.
But we have seen that the standard of ordinary examinations is false, even as regards pure intelligence. Critical judgment and imaginative power of combination have a much greater intellectual value than memory or the power of assimilation. It is, therefore, not to be wondered at that the boy who is at the top of his class so often turns out a failure, while the dunce who failed in his examinations sometimes becomes a genius or at any rate a very useful and capable man. From such facts, which are extremely common, it is falsely concluded, by a kind of fatalism, that "one never knows what will become of a man, for personalities change so much." This false conclusion is simply due to the erroneous criterion which is used in the evaluation of childhood, combined with the disgust inspired in strong and original minds by our schools.
Diseases and other accidents may sometimes hinder the development of good dispositions, or even cause them to abort completely. Nevertheless, we shall rarely make false prophecies if we begin by avoiding the gross errors that we have pointed out in the mental evaluation of youth. It is also necessary to institute extensive psychological observations on the development of individuals, and in the value of their work at adult age compared with their peculiarities observed in childhood. I am certain that in this way the social value of a young man, or even a child, and in general all members of human society, could be calculated in advance in a more exact way.
Domestic Animals and Plants.—The weak constitution of the domestic varieties of plants and animals has been used as an argument against human selection. If the animal and vegetable varieties which we raise by artificial selection have not enough strength when left to themselves, this is due to the fact that in creating them we have not consulted their interests in the struggle for existence, but only our own. For example, we raise for our own use fat pigs which can scarcely walk, pear trees with succulent fruit which has very few seeds, etc. It is obvious that these monstrosities cannot be expected to maintain themselves in the struggle for existence. Human selection, on the contrary, is only concerned with what is advantageous for man, individually as well as socially. It is, therefore, not a question of a Utopian hypothesis, but of facts, the daily consequences of which we can observe in society, if we only look at them without prejudice.
Calculation of Averages.—Francis Galton has studied this question by the aid of the law of variations and by the calculation of probabilities. This law only deals with so-called fortuitous elements, due to thousands of minute causes which act to a great extent against each other and become mutually compensated in their general effect, so that the two extremes are always represented by small numbers and the average by large numbers. But, when certain special and greater forces come into play, the general resultant is deviated in one direction or the other.
Galton shows that this law applies to social relations and mental values as well as to the stature of the body. In a given society there are always some individuals who are very good, some very bad, and many mediocrities. When a powerful general factor, such as alcohol or corruption by money, lowers all the individual values, the total value of the whole scale of capacities is lowered. Galton shows that the average values can be appreciably raised by inducing the class of higher values to reproduce themselves, and by preventing the lower values from doing so.
Prof. Jules Amann has shown how the immigration of the Huguenots into Switzerland and Germany after the Revocation of the Edict of Nantes by Louis XIV (1685) contributed to raise the mental level in these countries and continues to do so at the present day.
Visions of the Past and Future.—It is always sad to see capable, hard-working men and women, very useful from the social point of view, remaining sterile, simply on account of our social or religious prejudices; whereas, for the benefit of the community, they ought to marry as young as possible and procreate numerous children.
I have already said (the idea is found in André Couvreur's La Graine) that, if the sterility of one of the conjoints in marriage unfortunately leads to sterility in the other conjoint, the law, to make good the loss, should allow bigamy or concubinage in favor of the second, when the latter is very capable. I cannot dwell too strongly on the necessity of compensating for the sterilization which is so necessary with ill-formed or incapable beings, as well as for the period of rest which is due to women between their confinements, by an energetic multiplication of all useful and capable individuals.
In the same way, it is a real pity to see so many healthy, active and intelligent girls become old maids, simply because they have no money and do not wish to throw themselves at the first scamp who comes. It would be far better to allow a little free polygamy, with complete equality of the two sexes and certain legal precautions, than to lose so much good seed and grow so many weeds. I refer the reader to what I have said on the duties of parents toward their children, and on the duties of society toward the procreators of healthy children. (Chapter XIII.)
