_Seeming Wastefulness of the Cosmic Process_

But as we look still further into the matter, our mood is changed once

more. We find that this hideous hatred and strife, this wholesale famine

and death, furnish the indispensable conditions for the evolution of

higher and higher types of life. Nay more, but for the pitiless

destruction of all individuals that fall short of a certain degree of

fitness to the circumstances of life into which they are born, the type

would inevitably degenerate, the life would become lower and meaner in

kind. Increase in richness, variety, complexity of life is gained only

by the selection of variations above or beyond a certain mean, and the

prompt execution of a death sentence upon all the rest. The principle of

natural selection is in one respect intensely Calvinistic; it elects

the one and damns the ninety and nine. In these processes of Nature

there is nothing that savours of communistic equality; but "to him that

hath shall be given, and from him that hath not shall be taken away even

that which he hath." Through this selection of a favoured few, a higher

type of life--or at all events a type in which there is more life--is

attained in many cases, but not always. Evolution and progress are not

synonymous terms. The survival of the fittest is not always a survival

of the best or of the most highly organized. The environment is

sometimes such that increase of fitness means degeneration of type, and

the animal and vegetable worlds show many instances of degeneration. One

brilliant instance is that which has preserved the clue to the remote

ancestry of the vertebrate type. The molluscoid ascidian, rooted

polyp-like on the sea beach in shallow water, has an embryonic history

which shows that its ancestors had once seen better days, when they

darted to and fro, fishlike, through the waves, with the prophecy of a

vertebrate skeleton within them. This is a case of marked degeneration.

More often survival of the fittest simply preserves the type unchanged

through long periods of time. But now and then under favourable

circumstances it raises the type. At all events, whenever the type is

raised, it is through survival of the fittest, implying destruction of

all save the fittest.

This last statement is probably true of all plants and of all animals

except that as applied to the human race it needs some transcendently

important qualifications which students of evolution are very apt to

neglect. I shall by and by point out these qualifications. At present we

may note that the development of civilization, on its political side,

has been a stupendous struggle for life, wherein the possession of

certain physical and mental attributes has enabled some tribes or

nations to prevail over others, and to subject or exterminate them. On

its industrial side the struggle has been no less fierce; the evolution

of higher efficiency through merciless competition is a matter of common

knowledge. Alike in the occupations of war and in those of peace,

superior capacity has thriven upon victories in which small heed has

been paid to the wishes or the welfare of the vanquished. In human

history perhaps no relation has been more persistently repeated than

that of the hawk and the wren. The aggression has usually been defended

as in the interests of higher civilization, and in the majority of cases

the defence has been sustained by the facts. It has indeed very commonly

been true that the survival of the strongest is the survival of the

fittest.

Such considerations affect our mood toward Nature in a way that is

somewhat bewildering. On the one hand, as we recognize in the universal

strife and slaughter a stern discipline through which the standard of

animate existence is raised and the life of creatures variously

enriched, we become to some extent reconciled to the facts. Assuming,

as we all do, that the attainment of higher life is in itself desirable,

our minds cannot remain utterly inhospitable towards things, however

odious in themselves, that help toward the desirable end. Since we

cannot rid the world of them, we acquiesce in their existence as part of

the machinery of God's providence, the intricacies of which our finite

minds cannot hope to unravel. On the other hand, a thought is likely to

arise which in days gone by we should have striven to suppress as too

impious for utterance; but it is wiser to let such thoughts find full

expression, for only thus can we be sure of understanding the kind of

problem we are trying to solve. Is not, then, this method of Nature,

which achieves progress only through misery and death, an exceedingly

brutal and clumsy method? Life, one would think, must be dear to the

everlasting Giver of life, yet how cheap it seems to be held in the

general scheme of things! In order that some race of moths may attain a

certain fantastic contour and marking of their wings, untold thousands

of moths are doomed to perish prematurely. Instead of making the

desirable object once for all, the method of Nature is to make something

else and reject it, and so on through countless ages, till by slow

approximations the creative thought is realized. Nature is often called

thrifty, yet could anything be more prodigal or more cynical than the

waste of individual lives? Does it not remind one of Charles Lamb's

famous story of the Chinaman whose house accidentally burned down and

roasted a pig, whereupon the dainty meat was tasted and its fame spread

abroad until epicures all over China were to be seen carrying home pigs

and forthwith setting fire to their houses? We need but add that the

custom thus established lasted for centuries, during which every dinner

of pig involved the sacrifice of a homestead, and we seem to have a

close parody upon the wastefulness of Nature, or of what is otherwise

called in these days the Cosmic Process. Upon such a view as this the

Cosmic Process appears in a high degree unintelligent, not to say

immoral.
