End of the Working of Natural Selection upon Man. Throwing off the

Brute-Inheritance.

As regards the significance of Man's position in the universe, this

gradual elimination of strife is a fact of utterly unparalleled

grandeur. Words cannot do justice to such a fact. It means that the

wholesale destruction of life, which has heretofore characterized

evolution ever since life began, and through which the higher forms of

organic existence have been produced, must presently come to an end in

the case of the chief of God's creatures. It means that the universal

struggle for existence, having succeeded in bringing forth that

consummate product of creative energy, the Human Soul, has done its work

and will presently cease. In the lower regions of organic life it must

go on, but as a determining factor in the highest work of evolution it

will disappear.

The action of natural selection upon Man has long since been essentially

diminished through the operation of social conditions. For in all grades

of civilization above the lowest, "there are so many kinds of

superiorities which severally enable men to survive, notwithstanding

accompanying inferiorities, that natural selection cannot by itself

rectify any particular unfitness." In a race of inferior animals any

maladjustment is quickly removed by natural selection, because, owing to

the universal slaughter, the highest completeness of life possible to a

given grade of organization is required for the mere maintenance of

life. But under the conditions surrounding human development it is

otherwise.[14] There is a wide interval between the highest and lowest

degrees of completeness of living that are compatible with maintenance

of life.

Hence the wicked flourish. Vice is but slowly eliminated, because

mankind has so many other qualities, beside the bad ones, which enable

it to subsist and achieve progress in spite of them, that natural

selection--which always works through death--cannot come into play. The

improvement of civilized man goes on mainly through processes of direct

adaptation. The principle in accordance with which the gloved hand of

the dandy becomes white and soft while the hand of the labouring man

grows brown and tough is the main principle at work in the improvement

of Humanity. Our intellectual faculties, our passions and prejudices,

our tastes and habits, become strengthened by use and weakened by

disuse, just as the blacksmith's arm grows strong and the horse turned

out to pasture becomes unfit for work. This law of use and disuse has

been of immense importance throughout the whole evolution of organic

life. With Man it has come to be paramount.

If now we contrast the civilized man intellectually and morally with the

savage, we find that, along with his vast increase of cerebral surface,

he has an immensely greater power of representing in imagination objects

and relations not present to the senses. This is the fundamental

intellectual difference between civilized men and savages.[15] The power

of imagination, or ideal representation, underlies the whole of science

and art, and it is closely connected with the ability to work hard and

submit to present discomfort for the sake of a distant reward. It is

also closely connected with the development of the sympathetic feelings.

The better we can imagine objects and relations not present to sense,

the more readily we can sympathize with other people. Half the cruelty

in the world is the direct result of stupid incapacity to put one's self

in the other man's place. So closely inter-related are our intellectual

and moral natures that the development of sympathy is very considerably

determined by increasing width and variety of experience. From the

simplest form of sympathy, such as the painful thrill felt on seeing

some one in a dangerous position, up to the elaborate complication of

altruistic feelings involved in the notion of abstract justice, the

development is very largely a development of the representative faculty.

The very same causes, therefore, deeply grounded in the nature of

industrial civilization, which have developed science and art, have also

had a distinct tendency to encourage the growth of the sympathetic

emotions.

But, as already observed, these emotions are still too feebly developed,

even in the highest races of men. We have made more progress in

intelligence than in kindness. For thousands of generations, and until

very recent times, one of the chief occupations of men has been to

plunder, bruise, and kill one another. The selfish and ugly passions

which are primordial--which have the incalculable strength of

inheritance from the time when animal consciousness began--have had but

little opportunity to grow weak from disuse. The tender and unselfish

feelings, which are a later product of evolution, have too seldom been

allowed to grow strong from exercise. And the whims and prejudices of

the primeval militant barbarism are slow in dying out from the midst of

peaceful industrial civilization. The coarser forms of cruelty are

disappearing, and the butchery of men has greatly diminished. But most

people apply to industrial pursuits a notion of antagonism derived from

ages of warfare, and seek in all manner of ways to cheat or overreach

one another. And as in more barbarous times the hero was he who had

slain his tens of thousands, so now the man who has made wealth by

overreaching his neighbours is not uncommonly spoken of in terms which

imply approval. Though gentlemen, moreover, no longer assail one another

with knives and clubs, they still inflict wounds with cruel words and

sneers. Though the free--thinker is no longer chained to a stake and

burned, people still tell lies about him, and do their best to starve

him by hurting his reputation. The virtues of forbearance and

self-control are still in a very rudimentary state, and of mutual

helpfulness there is far too little among men.

Nevertheless in all these respects some improvement has been made, along

with the diminution of warfare, and by the time warfare has not merely

ceased from the earth but has come to be the dimly remembered phantom of

a remote past, the development of the sympathetic side of human nature

will doubtless become prodigious. The manifestation of selfish and

hateful feelings will be more and more sternly repressed by public

opinion, and such feelings will become weakened by disuse, while the

sympathetic feelings will increase in strength as the sphere for their

exercise is enlarged. And thus at length we see what human progress

means. It means throwing off the brute-inheritance,--gradually throwing

it off through ages of struggle that are by and by to make struggle

needless. Man is slowly passing from a primitive social state in which

he was little better than a brute, toward an ultimate social state in

which his character shall have become so transformed that nothing of the

brute can be detected in it. The ape and the tiger in human nature will

become extinct. Theology has had much to say about original sin. This

original sin is neither more nor less than the brute-inheritance which

every man carries with him, and the process of evolution is an advance

toward true salvation. Fresh value is thus added to human life. The

modern prophet, employing the methods of science, may again proclaim

that the kingdom of heaven is at hand. Work ye, therefore, early and

late, to prepare its coming.
