THE ARRIVAL OF THE FIT

In my youth I once heard the then well-known lecturer Starr King speak

on "The Law of Disorder." I have no recollection of the main thought of

his discourse, but can see that it might have been upon the order and

harmony that finally come out of the disharmonies of nature and of man.

The whole universe goes blundering on, but surely arrives. Collisions

and dispersions in the heavens above, and failure and destruction among

living things on the earth below, yet here we all are in a world good to

be in! The proof that it is good to be in is that we are actually here.

It is as if the Creator played his right hand against his left--what one

loses the other gains.

It has been aptly said that while Darwin's theory of natural selection

may account for the survival of the fittest, it does not account for the

arrival of the fittest. The arrival of the fittest, sooner or later,

seems in some way guaranteed by tendencies that are beyond the

hit-and-miss method of natural selection.

When we look back over the course of organic evolution, we see the

unfolding of a great drama, or tragedy, in which, for millions upon

millions of years the sole actors are low and all but brainless forms

of life, devouring and devoured, in the old seas. We see, during other

millions upon millions of years, a savage carnival of huge bestial forms

upon the land, amphibian monsters and dragons of the land and air,

devouring and being devoured, a riot of blood and carnage. We see the

shifting of land and sea, the folding and crumpling of the earth's

crust, the rise of mountains, the engulfing of forests, a vast

destruction of life, immense numbers of animal forms becoming extinct

through inability to adapt themselves to new conditions, or from other

causes. We see creatures, half beast, half bird, or half dragon, half

fish; we see the evolutionary process thwarted or delayed apparently by

the hardening or fixing of its own forms. We see it groping its way like

a blind man, and experimenting with this device and with that, fumbling,

awkward, ineffectual, trying magnitude of body and physical strength

first, and then shifting the emphasis to size of brain and delicacy and

complexity of nerve-organization, pushing on but gropingly, learning

only by experience, regardless of pain and waste and suffering; whole

races of sentient beings swept away by some terrestrial cataclysm, as at

the end of Palæozoic and Mesozoic times; prodigal, inhuman, riotous,

arming some vegetable growths with spurs and thorns that tear and stab,

some insects with stings, some serpents with deadly fangs, the

production of pain as much a part of the scheme of things as the

production of pleasure; the creative impulse feeling its way through the

mollusk to the fish, and through the fish to the amphibian and the

reptile, through the reptile to the mammal, and through the mammal to

the anthropoid apes, and through the apes to man, then through the rude

and savage races of man, the long-jawed, small-brained, Pliocene man,

hairy and savage, to the cave-dwellers and stone-implement man of

Pleistocene times, and so on to our rude ancestors whom we see dimly at

the dawn of history, and thus rapidly upward to the European man of our

own era. What a record! What savagery, what thwartings and delays, what

carnage and suffering, what an absence of all that we mean by

intelligent planning and oversight, of love, of fatherhood! Just a clash

of forces, the battle to the strong and the race to the fleet.

It is hard to believe that the course of organic evolution would have

eventuated in man and the other higher forms of life without some

guiding principle; yet it is equally difficult to believe that the

course of any guiding intelligence down the ages would have been strewn

with so many failures and monstrosities, so much waste and suffering and

delay. Man has not been specially favored by one force or element in

nature. Behold the enemies that beset him without and within, and that

are armed for his destruction! The intelligence that appears to pervade

the organic world, and that reaches its conscious expression in the

brain of man, is just as manifest in all the forms of animals and plants

that are inimical to him, in all his natural enemies,--venomous snakes

and beasts of prey, and insect pests,--as in anything else. Nature is as

wise and solicitous for rats and mice as for men. In fact, she has

endowed many of the lower creatures with physical powers that she has

denied him. Evidently man is only one of the cards in her pack;

doubtless the highest one, but the game is not played for him alone.

There is no economy of effort or of material in nature as a whole,

whatever there may be in special parts. The universe is not run on

modern business-efficiency principles. There is no question of time, or

of profit, of solvency or insolvency. The profit-and-loss account in the

long run always balances. In our astronomic age there are probably

vastly more dead suns and planets strewing the depths of sidereal space

than there are living suns and planets. But in some earlier period in

the cycle of time the reverse may have been true, or it may be true in

some future period.

There is economy of effort in the individual organism, but not in the

organic series, at least from the human point of view. During the

biologic ages there have been a vast number of animal forms, great and

small, and are still, that had no relation to man, that were not in his

line of descent, and played no part in his evolution. During that

carnival of monstrous and gigantic forms in Mesozoic time the ancestor

of man was probably some small and insignificant creature whose life was

constantly imperiled by the huge beasts about it. That it survived at

all in the clash of forces, bestial and elemental, during those early

ages, is one of the wonders of time. The drama or tragedy of evolution

has had many actors, some of them fearful and terrible to look upon, who

have played their parts and passed off the stage, as if the sole purpose

was the entertainment of some unseen spectator. When we reach human

history, what wasted effort, what failures, what blind groping, what

futile undertakings!--war, famine, pestilence, delaying progress or

bringing to naught the wisdom of generations of men! Those who live in

this age are witnessing in the terrible European war something analogous

to the blind, wasteful fury of the elemental forces; millions of men who

never saw one another, and who have not the shadow of a quarrel, engage

in a life-and-death struggle, armed with all the aids that centuries of

science and civilization can give them--a tragedy that darkens the very

heavens and makes a mockery of all our age-old gospel of peace and good

will to men. It is a catastrophe on a scale with the cataclysms of

geologic time when whole races disappeared and the face of continents

was changed. It seems that men in the aggregate, with all their science

and religion, are no more exempt from the operation of cosmic laws than

are the stocks and stones. Each party to this gigantic struggle declares

that he is in it against his will; the fate that rules in the solar

system seems to have them all in its grip; the working of forces and

tendencies for which no man was responsible seems to have brought it

about. Social communities grow in grace and good-fellowship, but

governments in their relations to one another, and often in relation to

their own subjects, are still barbarous. Men become christianized, but

man is still a heathen, the victim of savage instincts. In this struggle

one of the most admirable and efficient of nations, and one of the most

solicitous for the lives and well-being of its citizens, is suddenly

seized with a fury of destruction, hurling its soldiers to death as if

they were only the waste of the fields, and trampling down other peoples

whose geographic position placed them in their way as if they were

merely vermin, throwing international morality to the winds, looking

upon treaties as "scraps of paper," regarding themselves as the salt of

the earth, the chosen of the Lord, appropriating the Supreme Being as

did the colossal egotism of old Israel, and quickly getting down to the

basic principle of savage life--that might makes right.

Little wonder that the good people are asking, Have we lost faith? We

may or we may not have lost faith, but can we not see that our faith

does not give us a key to the problem? Our faith is founded on the old

prescientific conception of a universe in which good and evil are

struggling with each other, with a Supreme Being aiding and abetting the

good. We fail to appreciate that the cosmic laws are no respecters of

persons. Emerson says there is no god dare wrong a worm, but worms dare

wrong one another, and there is no god dare take sides with either. The

tides in the affairs of men are as little subject to human control as

the tides of the sea and the air. We may fix the blame of the European

war upon this government or upon that, but race antagonisms and

geographical position are not matters of choice. An island empire, like

England, is bound to be jealous of all rivals upon the sea, because her

very life, when nations clash, depends upon her control of it; and an

inland empire, like Germany, is bound to grow restless under the

pressure of contiguous states of other races. A vast empire, like

Russia, is always in danger of falling apart by its own weight. It is

fused and consolidated by a turn of events that arouse the patriotic

emotions of the whole people and unite them in a common enthusiasm.

The evolution of nations is attended by the same contingencies, the same

law of probability, the same law of the survival of the fit, as are

organic bodies. I say the survival of the fit; there are degrees of

fitness in the scale of life; the fit survive, and the fittest lead and

dominate, as did the reptiles in Mesozoic time, and the mammals in

Tertiary time. Among the mammals man is dominant because he is the

fittest. Nations break up or become extinct when they are no longer fit,

or equal to the exigencies of the struggles of life. The Roman Empire

would still exist if it had been entirely fit. The causes of its

unfitness form a long and intricate problem. Germany of to-day evidently

looks upon herself as the dominant nation, the one fittest to survive,

and she has committed herself to the desperate struggle of justifying

her self-estimate. She tramples down weaker nations as we do the stubble

of the fields. She would plough and harrow the world to plant her

Prussian _Kultur_. This _Kultur_ is a mighty good product, but we

outside of its pale think that French _Kultur_, and English _Kultur_,

and American _Kultur_ are good products also, and equally fit to

survive. We naturally object to being ploughed under. That Russian

_Kultur_ has so far proved itself a vastly inferior product cannot be

doubted, but the evolutionary processes will in time bring a finer and

higher Russia out of this vast weltering and fermenting mass of

humanity. In all these things impersonal laws and forces are at work,

and the balance of power, if temporarily disturbed, is bound, sooner or

later, to be restored just as it is in the inorganic realm.

Evolution is creative, as Bergson contends. The wonder is that,

notwithstanding the indifference of the elemental forces and the blind

clashing of opposing tendencies among living forms,--a universe that

seems run entirely on the trial-and-error principle,--evolution has gone

steadily forward, a certain order and stability has been reached in the

world of inert bodies and forces, and myriads of forms of wonderful

fitness and beauty have been reached in the organic realm. Just as the

water-system and the weather-system of the globe have worked themselves

out on the hit-and-miss plan, but not without serious defects,--much too

much water and heat at a few places, and much too little at a few

others,--so the organic impulse, warred upon by the blind inorganic

elements and preyed upon by the forms it gave rise to, has worked itself

out and peopled the world as we see it peopled to-day--not with forms

altogether admirable and lovely from our point of view, but so from the

point of view of the whole. The forests get themselves planted by the

go-as-you-please winds and currents, the pines in one place, the spruce,

the oaks, the elms, the beeches, in another, all with a certain fitness

and system. The waters gather themselves together in great bodies and

breathe salubrity and fertility upon the land.

A certain order and reasonableness emerges from the chaos and

cross-purposes. There are harmony and coöperation among the elemental

forces, as well as strife and antagonism. Life gets on, for all groping

and blundering. There is the inherent variability of living forms to

begin with--the primordial push toward the development from within

which, so far as we can see, is not fortuitous, but predestined; and

there is the stream of influences from without, constantly playing upon

and modifying the organism and taken advantage of by it.

The essence of life is in adaptability; it goes into partnership with

the forces and conditions that surround it. It is this trait which leads

the teleological philosopher to celebrate the fitness of the environment

when its fitness is a foregone conclusion. Shall we praise the fitness

of the air for breathing, or of the water for drinking, or of the winds

for filling our sails? If we cannot say explicitly, without speaking

from our anthropomorphism, that there is a guiding intelligence in the

evolution of living forms, we can at least say, I think, that the

struggle for life is favored by the very constitution of the universe

and that man in some inscrutable way was potential in the fiery nebula

itself.
