TO BASIL HALL CHAMBERLAIN

KŌBE, April, 1895.

DEAR CHAMBERLAIN,--"The law of heredity is unlimited in its application"

(Spencer, "Biology," vol. I, chapter "Heredity"). "Some naturalists

seem to entertain a vague belief [like yours?] that the law of heredity

applies only to main characters of structure, and not to details; or

that though it applies to such details as constitute differences of

species, it does not apply to smaller details. The circumstance that the

tendency to repetition is in a slight degree qualified by the tendency

to variation (which ... is but an indirect result of the tendency

to repetition) leads some to doubt whether heredity is unlimited. A

careful weighing of the evidence ... will remove the ground for this

skepticism." ("Biology," vol. I, p. 239.)

Your statement that the "weak person will always remain weak," but that

"the manifestations of his weakness will surely depend on the nature of

the obstacles in his way," is a proof that you do not perceive the full

reach of the explanation. The manifestations of weakness may be evoked

by obstacles, but the nature of those manifestations cannot possibly

have anything in common with the nature of the obstacles. The weakness

being hereditary, the nature of the obstacle cannot change it.

The case of the Northern nations seems to me direct proof of the

contrary to what you suggest. Olaf Trygvesson and others never really

changed the national religion, except in name,--no such rapid change

would have been possible. The worship of Odin and Thor continued under

the name of Christ and the Saints,--and still continues to some extent

to influence English life. The shaking-off of ecclesiastical power at a

later day,--the protestantizing of the Northern races,--is certainly the

manifestation in history of the same fierce love of freedom that founded

the Icelandic Republic. So with English limitation of monarchical power,

the history of the constitution, etc. So with the superiority of English

and Norse seamanship to-day,--Vikings still command our fleet. The

changes you cite as evidence of the non-influence of heredity really

prove it: they are, moreover, mere surface-shiftings of colour, and do

not reach down into the national life. Variations are the result of

heredity, not the exceptions to it. The explanation of this fact would

necessitate, however, a long discussion on the deepening or weakening

of those channels of nerve-force which are the river-courses of life

and thought. Similarly, growth--of brain and thought as well as of

body--is the consequence, not the contradiction, of inheritance. So with

instinct,--which is organized memory,--and with genius, which represents

accumulations of capacity (often at the expense of other growths).

I fear you think of Galton only when you limit the word heredity.

Universal life and growth is touched by the larger meaning: Galton's

wonderful books represent merely a domestic paragraph of the subject.

The underlying principles of evolution--the deep laws of physiological

growth and development--involve far vaster and profounder consideration

of the subject. Inheritance is no "fad:" it means you and me and the

world and our central sun.

My text was plain,--but you have forgotten it. I spoke of "ancestral

pleasure," "hereditary delight." You deny their possibility. The toys

are not ancestral, of course, nor did I say they were,--but they

appealed to ancestral feeling. Why? All pleasure is hereditary--every

feeling is inherited. Why, then, say so? Because in this case we are

considering race-feelings widely differentiated from our own.

But all this is surface,--the ghostly side of the question is the

beautiful one, and one which you would not deny without examining

the evidence? Perhaps you think that the first time you saw Fuji or

Miyanoshita, you had really a new sensation. But you had nothing of

the kind. The sensations of that new experience in your own life

were millions of years old! Far from simple is the commonest of our

pleasures, but a layer, infinitely multiple, of myriads of millions

of ancestral impressions. Try to analyze the sensation of pleasure in

a sunrise, or the smell of hay, and how soon we are lost. We can only

classify the elements of such a pleasure "by bundles," so to speak.

It might at first sight shock a strong soul to perceive itself not

individual and original, but an infinite compound. But I think one's

pride in one's good should subsequently expand. The thought that one's

strength is the strength of one's ancestors--of a host innumerable and

ancient as the race--has its larger consolation. And here is the poetry

of the thing. You are my friend B. H. C. But you are much more--you are

also Captain B. H., and a host of others--doubtless Viking and Norman

and Danish--a procession reaching back into the weird twilight of the

Northern gods.

So much for the fun of our discussion. I won't send the long screed:

it is too full of dry stuff, and on reading it over I find that my

enthusiasm betrayed me into several wild misstatements.

I am sorry about your cold, and I can sympathize; for I also have been

ill, and my boy, and I find spring very trying. I am all right to-day,

and so are we all.

Wish I were nineteen years old, and, like Ben, going to sea. As a boy, I

cried and made a great fuss because they told me, "You can't go to sea:

you are too near-sighted." Perhaps I was saved from disillusions.

You know Frederick Soulié's "Si jeunesse savait, si vieillesse pouvait."

There was an unconscious recognition of heredity,--before modern biology

had been synthetized.

Ever with best wishes and regards,

LAFCADIO HEARN.
