[CHAPTER III]
NATURAL SELECTION AND THE LAW OF LOVE
“Truth justifies herself; and as she dwells
With hope, who would not follow where she leads?”
Wordsworth.
“La plus haute tâche de l'action morale est le travail pour le bien des générations futures.”—Forel.
Before looking more closely than we are commonly apt to do at the meaning of the phrases “natural selection” and “survival of the fittest,” let us exercise the right of man the moral being, as distinguished from man the scientist or observer of Nature, to pass ethical judgments upon the facts which it is the business of all the sciences, except ethics itself, merely to record and interpret in and for themselves. We are beginning at last, half a century after the publication of the Origin of Species in 1859, to realise the power of the law of selection; what is the moral judgment which is to be passed upon it? In a passage from the last page of Herbert Spencer's Autobiography, we find words which may be quoted on both sides: “When we think of the myriads of years of the Earth's past, during which have arisen and passed away low forms of creatures, small and great, which, murdering and being murdered, have gradually evolved,[5] how shall we answer the question—To what end?”
“Murdering and being murdered” suggests the adverse, and “have gradually evolved,” the favourable, ethical judgment.
Many thinkers, finding Nature “so careless of the single life,” finding the murderous struggle for existence the dominant fact of the history of the living world, return an adverse verdict. Amongst them are to be found not merely those who are inclined, by temperament or imperfect education, to rebellion against any conclusions of science, but also, as we saw in the second chapter, such a great biologist as Huxley. In another part of the lecture already cited he says that the Stoics failed to see
“... that cosmic nature is no school of virtue, but the headquarters of the enemy of ethical nature. The logic of facts was necessary to convince them that the cosmos works through the lower nature of man, not for righteousness, but against it.... The practice of that which is ethically best—what we call goodness or virtue—involves a course of conduct which, in all respects, is opposed to that which leads to success in the cosmic struggle for existence.”
In other words, honesty is the worst policy: and to worship natural selection is to deify the devil.
The reader will realise that, if we are to succeed in establishing the claim of natural selection to be the natural model upon which those who desire the progress of society are to base their policy, it is necessary to controvert the doctrine that natural selection is an anti-moral process. But let us hear the other side.
