“The great law of variation teaches--both in the general theory of evolution and in the smaller field of biology where it becomes the theory of descent--that the variety of phenomena flows from an original unity, the diversity of functions from a primitive identity, and the complexity of organization from a primordial simplicity. The conditions of existence for all individuals are, from their very birth, unequal. There must also be taken into consideration the inherited qualities and the innate tendencies, which also vary more or less widely. In view of all this, how can the work and the reward be equal for all? “The more highly the social life is developed, the more important becomes the great principle of the division of labor, the more requisite it becomes for the stable existence of the state as a whole that its members should distribute among themselves the multifarious tasks of life, each performing a single function; and as the labor which must be performed by the individuals, as well as the expenditure of strength, talent, money, etc., which it necessitates, differs more and more, it is natural that the remuneration of this labor must also vary widely. These are facts so simple and so obvious that it seems to me every intelligent and enlightened statesman ought to be an advocate of the theory of descent and the general doctrine of evolution as the best antidote for the absurd equalitarian, utopian notions of the Socialists. “And it was Darwinism, the theory of selection, that Virchow, in his denunciation, had in mind, rather than the mere metamorphic development, the theory of descent, with which it is always confused! Darwinism is anything rather than socialistic. “If one wishes to attribute a political tendency to this English theory--which is quite permissible--this tendency can be nothing but aristocratic; by no means can it be democratic, still less socialistic. “The theory of selection teaches that in the life of mankind, as in that of plants and animals, it is always and everywhere a small and privileged minority alone which succeeds in living and developing itself; the immense majority, on the contrary suffer and succumb more or less prematurely. Countless are the seeds and eggs of every species of plants and animals, and the young individuals who issue from them. But the number of those who have the good fortune to reach fully developed maturity and to attain the goal of their existence is relatively insignificant.
