CHAPTER II

HEREDITY AND ENVIRONMENT

Eugenics is not committed to the Darwinian doctrine of evolution,

although it would probably never have reached the stage of practical

politics but for the encouragement given to all systematic scientific

studies by Darwin's magnificent generalisations. Eugenics takes its

stand on the ascertained fact of heredity, and it owes an immense debt

to the patience with which Lamarck, the Darwins, Weissman and others

have piled instance upon instance to illustrate the fact that "the sins

of the fathers are visited upon the children unto the third and fourth

generation" and "the fathers have eaten sour grapes and the children's

teeth are set on edge." The doctrine of heredity has never been more

resonantly expressed than in these words although they show only one

side and that not the better side of heredity. We are indeed "begotten

not made." Nurture, or environment, has its place, and an important

one, in race improvement, but the overwhelming fact remains that

more than three-fourths of the elements which build up a human soul

are in its nature, not its nurture. The formative factor of greatest

importance in the making of human life and character is heredity.

Mankind has hitherto failed to grasp the full significance of this

admission. Horticulturists have made it the starting point of their

experiments until to-day the Luther Burbanks can almost create

what they will in plant life. Cattle-breeders, dog-fanciers, and

horse-farmers, are able to raise the value of their breeds to a

wonderful degree. Ornithologists have been equally successful; from the

original stock a hundred varieties come at the touch of the scientific

magician's wand. In each case even where at first quantity was

considered of no importance compared with quality, there has been a

steady and unmistakable increase in the effective numbers side by side

with a gigantic development of those elements of strength or beauty

which have been arrived at. Race suicide is a metaphysical phrase not

easily open to definition, but two things may be said about it at this

stage. Race improvement is utterly inconsistent with any intelligent

conception of race suicide. An increasing birthrate is not in itself

a guarantee of progress and may indeed be the means of a nation's

retrogression. Experience and logic lead to the confident conclusion

that increased vitality means increased fecundity.

To acknowledge the law of heredity with its concomitant scientific

implications, must inevitably change our mental outlook in many

directions. Accordingly as we relatively place heredity or environment

first, our views on social politics will be fundamentally sound or

unsound. Taking a large view of society it must make an abysmal

difference whether we think the race can or cannot be improved

(not merely polished or even enlightened but really changed) by

_modifications of environment_. We can no longer pursue the same and

by the same means if we come to the conclusion that the individual is

either born a potential asset to society or "damned into existence,"

a permanent drain on his fellows' comfort and wealth, even a possible

miasma of infectious criminality.

I am a Eugenist because I believe that the nature we have received from

hereditary sources transcends in effectiveness all the nurture which

follows birth. Eugenics means seeking for facts and applying them to

solve the greatest of all problems--looking for light by which the race

may control its destiny. Heredity in the animal and vegetable world may

be considered dispassionately enough. Geology and astronomy are only

hereditary studies affecting the birth of worlds. But from human birth

and sex, the mysteries of creation in their divinest form, from _these_

branches of the study of heredity the flaming sword of prudery warns

us away. The subject of human sex has been the play-ground of neglect,

ignorance, bigotry, superstition, persecution and every other foe to

inquiry. It has been the object of worship but not of explanation, of

romance but not of science, of abuse, mutilation, misunderstanding,

but not of study, reason and generalization. Eugenics of course aims

at expressing the scientific side of the process of which love is the

artistic. The rare handful of brave men and women who against unique

opposition have forced this question to the front are not to be blamed

if up to now Eugenics can hardly be said to exist as a systematised

science. It is in the nature of things that as a philosophy Eugenics

is hardly more than a guess, a probability, an hypothesis. Doubt,

uncertainty and half-heartedness inevitably accompany a movement so

undeservedly discredited as this has been. Without the means to collect

the enormous body of facts required to justify national action the

Eugenists have been content to rely upon personal experiences, isolated

family histories and the normal and abnormal facts which newspapers,

biographies and daily life presented to them. Eugenists have wrestled

against difficulties like Hercules in the Augean stable or Paul in

the Ephesian arena. In fact the stable and the arena throw more light

on Eugenics than any at present available from the human animal. The

existent biology of Eugenics means a study of non-human life. There

is a sufficiently extensive literature and digest of experiments

relating to animal and plant life to serve as the stock in trade of

a fairly complete system of Eugenics--if only fuschias were men or

men were mules. External observations of animal and plant life cannot

universally apply to man even passively, while the active interference

of the human botanist in the affairs of the unprotesting plants

separates these from men by an unpassable chasm.

The first need then for Eugenic study is some systematic collection of

the ascertainable facts as far as they relate to human beings. This

implies sufficient scientific interest in the phenomena of parentage

to encourage widespread earnest patient desire to exchange information

and to steadily accumulate enough knowledge to justify experiment in

positive and negative Eugenics. No sane Eugenist advocates universal

State action based on the existent records, but it would be against

all good precedent if the absence of sufficient knowledge on a vital

subject were allowed to stultify the efforts of those who seek for

fuller information. Nothing but good will ensue if positive experiments

are boldly labelled as such, instead of pretending that our twilight

of investigation is the full light of perfect knowledge. Experiments

in positive Eugenics will take various forms. They began with the

most ordinary baby-shows; they proceeded through municipal prizes for

the healthiest offsprings. An important stage arose when premiums in

some cities began to be offered to all parents whose babies survived

the critical first year of life. These were elementary experiments,

based on the right motive but ignoring the element of heredity. The

experiments of the future must be on a surer foundation. The current

criteria of judgment are sound enough as far as they go, they encourage

careful nurture, but the limitations of the experiments are those of

an unscientific age. Obviously the next step in the same direction

is to discriminate. The haphazard chance that of fifty children

properly nourished one may be distinguished by its superior physique

does not materially help us to solve our problem if we stop at this

phase. Having found our healthiest child we might at least try to

discover the hereditary history of its progenitors and take steps

to encourage further offsprings from so promising a source. Imagine

a scientific cattle-breeder possessing a perfect bull, contented

that one of its offsprings should take a single prize! Not to unduly

strain the analogy we might with all decorum and wisdom circulate

what knowledge we can glean of those facts which have made perfection

possible. Are we to be everlastingly contented with news of the

romantic, sensational, abnormal and criminal phenomena of sex while

our newspapers and official records are silent concerning ordinary and

desirable experiences, their causes and their results? Heredity as

the basis of legislation is never dreamt of, while our statute books

are crowded with laws passed in a panic, laws which bear no ratio

to essential facts, and laws which look at the elementary passions

of mankind through the refractory media of prejudice, ignorance and

well-meaning misconception. It rarely if ever occurs to legislators

that a scientific system of society demands an acquaintance with

the recently accepted conclusions of our greatest thinkers. We are

suffering to-day from a pre-Darwinian government in almost all our

States. "Authorities" of all kinds are quoted in support of and against

any given proposal, but the "authorities" are seldom the fittest. In

earlier days latin tags were considered a worthy conclusion to a speech

in Senate or Legislature. Nowadays poetry or literature is called

into requisition. Darwin, Spencer and Galton should at least have

taught us to take trouble to learn all about the subject in hand and

what bearing the scientific discoveries of our generation have upon

particular problems. It is a disease of the age that we are conscious

of our national short-comings in only the vaguest possible way. We are

ignorant of the full extent of our misfortunes and we do not apply to

them the time, trouble and money which are a preliminary necessity to

discovering a remedy, and we forget the dynamic difference which must

be made in our treatment of race problems as soon as we accept heredity

as the controlling factor. But the preliminaries must be insisted

on. Investigation, collation, classification, generalisation, and

legislation, must be taken in their right order.

The difficulties in the way of investigating the laws which govern

heredity have as usual led to shirking the issue altogether. Even

when we look the difficulty straight in the face, we pass it by. We

have made a god of environment. Our best social efforts hitherto in

legislation, social conventions, conduct and educational ideals (and

in modern times even our religions), have come to consider environment

as of paramount importance. But take environment at its highest it can

only be the best soil for the best seed. _That_ is a Eugenic ideal

also but it cannot convert a disease germ into a desirable citizen.

Over-emphasis of reform dependent on improved environment implies that

a deadly upas tree, if transplanted and properly watered and "given a

better chance," will reward society with a plentiful harvest of edible

nourishing fruit. The heartless school which on principles hates all

reform derives its chief support from the fact that the reform which

regards only environment too often descends to veneering vice with

respectability or dissipates itself in futilities of a grandmotherly

kind. The reformer of the future must study causes as well as

phenomena. The skilled physician regards symptoms as of importance

only to the extent that they assist the diagnosis of disease. Accurate

analysis must consider hereditary causes as well as local symptoms.

Environment when properly subordinated to and illuminated by heredity

does not cease to be important. Environment may provide wings to

fly with and an atmosphere capable of sustaining weight, even when

it cannot provide the will to fly. To return to our agricultural

symbolism: environment cannot make or change the nature of the seed, it

is the soil, the sunshine and the succulence, but it has to take the

seed as it is. Heredity is inside the seed and goes behind the seed to

the mother plant. Heredity is what our ancestors meant when they said

predestination, necessity, destiny.

Philosophers of pre-Darwin days have lured mankind into the pleasant

but dangerously untrue belief that human nature is essentially and

universally good. This crude generalisation of Rousseau's gospel

does some injustice to that great man's philosophy which represented

a necessary revolt from the soul-destroying perversion of heredity

which described man as uniformly "born in sin and shaped in iniquity."

Experience has revolted against both extremes. The Heavenly father is

no longer a Fiend who destines "one to heav'n and ten to hell," and

the Earthly Parent emerges from his ancient unimportance. Man is in

neither case fortuitous, his nature, potentiality and destiny are writ

large in the study of his heredity. We are all, like poets, born not

made; as we are: we remain: we develop on lines long ago laid down for

us by other forces than those environment can control and it is still

impossible to make a silk purse out of a sow's ear. This consideration

puts into proper perspective the things which matter, and warns us

to cease vain expenditure on unscientific philanthropy. The efforts

wasted on watering weeds might have made the garden smile with fragrant

flowers. Environment means opportunity. We shall understand better how

and why environments need reconstruction when we recognise the superior

importance of heredity. We shall begin to realise the uselessness of

forcing qualities into the human organism, and become all the more

anxious to afford opportunity for developing whatever utilisable

qualities are already there existent. We shall learn to educate, in

the old sense of the word. We shall bring out the maximum of the good

within. We will no longer tolerate the cruelties and crudities of

abortive attempts to instil properties and qualities of character which

not being inherent can never be successfully inoculated.
