I have quoted in all ninety-seven
passages, as near as I can make them, in which Mr.
Darwin claimed the theory of descent, either expressly
by speaking of “my theory” in such connection
that the theory of descent ought to be, and, as the
event has shown, was, understood as being intended,
or by implication, as in the opening passages of the
“Origin of Species,” in which he tells
us how he had thought the matter out without acknowledging
obligation of any kind to earlier writers. The
original edition of the “Origin of Species”
contained 490 pp., exclusive of index; a claim, therefore,
more or less explicit, to the theory of descent was
made on the average about once in every five pages
throughout the book from end to end; the claims were
most prominent in the most important parts, that is
to say, at the beginning and end of the work, and this
made them more effective than they are made even by
their frequency. A more ubiquitous claim than
this it would be hard to find in the case of any writer
advancing a new theory; it is difficult, therefore,
to understand how Mr. Grant Allen could have allowed
himself to say that Mr. Darwin “laid no sort
of claim to originality or proprietorship” in
the theory of descent with modification.
Nevertheless I have only found one
place where Mr. Darwin pinned himself down beyond
possibility of retreat, however ignominious, by using
the words “my theory of descent with modification.”
{202a} He often, as I have said, speaks of “my
theory,” and then shortly afterwards of “descent
with modification,” under such circumstances
that no one who had not been brought up in the school
of Mr. Gladstone could doubt that the two expressions
referred to the same thing. He seems to have
felt that he must be a poor wriggler if he could not
wriggle out of this; give him any loophole, however
small, and Mr. Darwin could trust himself to get out
through it; but he did not like saying what left no
loophole at all, and “my theory of descent with
modification” closed all exits so firmly that
it is surprising he should ever have allowed himself
to use these words. As I have said, Mr. Darwin
only used this direct categorical form of claim in
one place; and even here, after it had stood through
three editions, two of which had been largely altered,
he could stand it no longer, and altered the “my”
into “the” in 1866, with the fourth edition
of the “Origin of Species.”
This was the only one of the original
forty-five my’s that was cut out before the
appearance of the fifth edition in 1869, and its excision
throws curious light upon the working of Mr. Darwin’s
mind. The selection of the most categorical my
out of the whole forty-five, shows that Mr. Darwin
knew all about his my’s, and, while seeing reason
to remove this, held that the others might very well
stand. He even left “On my view of
descent with modification,” {203a} which, though
more capable of explanation than “my theory,”
&c., still runs it close; nevertheless the excision
of even a single my that had been allowed to stand
through such close revision as those to which the
“Origin of Species” had been subjected
betrays uneasiness of mind, for it is impossible that
even Mr. Darwin should not have known that though
the my excised in 1866 was the most technically categorical,
the others were in reality just as guilty, though
no tower of Siloam in the shape of excision fell upon
them. If, then, Mr. Darwin was so uncomfortable
about this one as to cut it out, it is probable he
was far from comfortable about the others.
This view derives confirmation from
the fact that in 1869, with the fifth edition of the
“Origin of Species,” there was a stampede
of my’s throughout the whole work, no less than
thirty out of the original forty-five being changed
into “the,” “our,” “this,”
or some other word, which, though having all the effect
of my, still did not say “my” outright.
These my’s were, if I may say so, sneaked out;
nothing was said to explain their removal to the reader
or call attention to it. Why, it may be asked,
having been considered during the revisions of 1861
and 1866, and with only one exception allowed to stand,
why should they be smitten with a homing instinct
in such large numbers with the fifth edition?
It cannot be maintained that Mr. Darwin had had his
attention called now for the first time to the fact
that he had used my perhaps a little too freely, and
had better be more sparing of it for the future.
The my excised in 1866 shows that Mr. Darwin had
already considered this question, and saw no reason
to remove any but the one that left him no loophole.
Why, then, should that which was considered and approved
in 1859, 1861, and 1866 (not to mention the second
edition of 1859 or 1860) be retreated from with every
appearance of panic in 1869? Mr. Darwin could
not well have cut out more than he did—not
at any rate without saying something about it, and
it would not be easy to know exactly what say.
Of the fourteen my’s that were left in 1869,
five more were cut out in 1872, and nine only were
allowed eventually to remain. We naturally ask,
Why leave any if thirty-six ought to be cut out, or
why cut out thirty-six if nine ought to be left—especially
when the claim remains practically just the same after
the excision as before it?
I imagine complaint had early reached
Mr. Darwin that the difference between himself and
his predecessors was unsubstantial and hard to grasp;
traces of some such feeling appear even in the late
Sir Charles Lyell’s “Principles of Geology,”
in which he writes that he had reprinted his abstract
of Lamarck’s doctrine word for word, “in
justice to Lamarck, in order to show how nearly the
opinions taught by him at the beginning of this century
resembled those now in vogue among a large body of
naturalists respecting the infinite variability of
species, and the progressive development in past time
of the organic world.” {205a} Sir Charles Lyell
could not have written thus if he had thought that
Mr. Darwin had already done “justice to Lamarck,”
nor is it likely that he stood alone in thinking as
he did. It is probable that more reached Mr.
Darwin than reached the public, and that the historical
sketch prefixed to all editions after the first six
thousand copies had been sold— meagre and
slovenly as it is—was due to earlier manifestation
on the part of some of Mr. Darwin’s friends
of the feeling that was afterwards expressed by Sir
Charles Lyell in the passage quoted above. I
suppose the removal of the my that was cut out in 1866
to be due partly to the Gladstonian tendencies of
Mr. Darwin’s mind, which would naturally make
that particular my at all times more or less offensive
to him, and partly to the increase of objection to
it that must have ensued on the addition of the “brief
but imperfect” historical sketch in 1861; it
is doubtless only by an oversight that this particular
my was not cut out in 1861. The stampede of 1869
was probably occasioned by the appearance in Germany
of Professor Haeckel’s “History of Creation.”
This was published in 1868, and Mr. Darwin no doubt
foresaw that it would be translated into English,
as indeed it subsequently was. In this book some
account is given—very badly, but still
much more fully than by Mr. Darwin— of
Lamarck’s work; and even Erasmus Darwin is mentioned—
inaccurately—but still he is mentioned.
Professor Haeckel says:-
“Although the theory of development
had been already maintained at the beginning of this
century by several great naturalists, especially by
Lamarck and Goethe, it only received complete demonstration
and causal foundation nine years ago through Darwin’s
work, and it is on this account that it is now generally
(though not altogether rightly) regarded as exclusively
Mr. Darwin’s theory.” {206a}
Later on, after giving nearly a hundred
pages to the works of the early evolutionists—pages
that would certainly disquiet the sensitive writer
who had cut out the “my” which disappeared
in 1866- he continued:
“We must distinguish clearly
(though this is not usually done) between, firstly,
the theory of descent as advanced by Lamarck, which
deals only with the fact of all animals and plants
being descended from a common source, and secondly,
Darwin’s theory of natural selection, which
shows us why this progressive modification of
organic forms took place” (p. 93).
This passage is as inaccurate as most
of those by Professor Haeckel that I have had occasion
to examine have proved to be. Letting alone
that Buffon, not Lamarck, is the foremost name in connection
with descent, I have already shown in “Evolution
Old and New” that Lamarck goes exhaustively
into the how and why of modification. He alleges
the conservation, or preservation, in the ordinary
course of nature, of the most favourable among variations
that have been induced mainly by function; this, I
have sufficiently explained, is natural selection,
though the words “natural selection” are
not employed; but it is the true natural selection
which (if so metaphorical an expression is allowed
to pass) actually does take place with the results
ascribed to it by Lamarck, and not the false Charles-Darwinian
natural selection that does not correspond with facts,
and cannot result in specific differences such as we
now observe. But, waiving this, the “my’s,”
within which a little rift had begun to show itself
in 1866, might well become as mute in 1869 as they
could become without attracting attention, when Mr.
Darwin saw the passages just quoted, and the hundred
pages or so that lie between them.
I suppose Mr. Darwin cut out the five
more my’s that disappeared in 1872 because he
had not yet fully recovered from his scare, and allowed
nine to remain in order to cover his retreat, and tacitly
say that he had not done anything and knew nothing
whatever about it. Practically, indeed, he had
not retreated, and must have been well aware that
he was only retreating technically; for he must have
known that the absence of acknowledgment to any earlier
writers in the body of his work, and the presence
of the many passages in which every word conveyed
the impression that the writer claimed descent with
modification, amounted to a claim as much when the
actual word “my” had been taken out as
while it was allowed to stand. We took Mr. Darwin
at his own estimate because we could not for a moment
suppose that a man of means, position, and education,—one,
moreover, who was nothing if he was not unself-seeking—could
play such a trick upon us while pretending to take
us into his confidence; hence the almost universal
belief on the part of the public, of which Professors
Haeckel and Ray Lankester and Mr. Grant Allen alike
complain—namely, that Mr. Darwin is the
originator of the theory of descent, and that his
variations are mainly functional. Men of science
must not be surprised if the readiness with which
we responded to Mr. Darwin’s appeal to our confidence
is succeeded by a proportionate resentment when the
peculiar shabbiness of his action becomes more generally
understood. For myself, I know not which most
to wonder at—the meanness of the writer
himself, or the greatness of the service that, in
spite of that meanness, he unquestionably rendered.
If Mr. Darwin had been dealing fairly
by us, when he saw that we had failed to catch the
difference between the Erasmus-Darwinian theory of
descent through natural selection from among variations
that are mainly functional, and his own alternative
theory of descent through natural selection from among
variations that are mainly accidental, and, above
all, when he saw we were crediting him with other men’s
work, he would have hastened to set us right.
“It is with great regret,” he might have
written, “and with no small surprise, that I
find how generally I have been misunderstood as claiming
to be the originator of the theory of descent with
modification; nothing can be further from my intention;
the theory of descent has been familiar to all biologists
from the year 1749, when Buffon advanced it in its
most comprehensive form, to the present day.”
If Mr. Darwin had said something to the above effect,
no one would have questioned his good faith, but it
is hardly necessary to say that nothing of the kind
is to be found in any one of Mr. Darwin’s many
books or many editions; nor is the reason why the requisite
correction was never made far to seek. For if
Mr. Darwin had said as much as I have put into his
mouth above, he should have said more, and would ere
long have been compelled to have explained to us wherein
the difference between himself and his predecessors
precisely lay, and this would not have been easy.
Indeed, if Mr. Darwin had been quite open with us
he would have had to say much as follows:-
“I should point out that, according
to the evolutionists of the last century, improvement
in the eye, as in any other organ, is mainly due to
persistent, rational, employment of the organ in question,
in such slightly modified manner as experience and
changed surroundings may suggest. You will have
observed that, according to my system, this goes for
very little, and that the accumulation of fortunate
accidents, irrespectively of the use that may be made
of them, is by far the most important means of modification.
Put more briefly still, the distinction between me
and my predecessors lies in this;- -my predecessors
thought they knew the main normal cause or principle
that underlies variation, whereas I think that there
is no general principle underlying it at all, or that
even if there is, we know hardly anything about it.
This is my distinctive feature; there is no deception;
I shall not consider the arguments of my predecessors,
nor show in what respect they are insufficient; in
fact, I shall say nothing whatever about them.
Please to understand that I alone am in possession
of the master key that can unlock the bars of the
future progress of evolutionary science; so great an
improvement, in fact, is my discovery that it justifies
me in claiming the theory of descent generally, and
I accordingly claim it. If you ask me in what
my discovery consists, I reply in this;—
that the variations which we are all agreed accumulate
are caused— by variation. {209a} I admit
that this is not telling you much about them, but
it is as much as I think proper to say at present;
above all things, let me caution you against thinking
that there is any principle of general application
underlying variation.”
This would have been right.
This is what Mr. Darwin would have had to have said
if he had been frank with us; it is not surprising,
therefore, that he should have been less frank than
might have been wished. I have no doubt that
many a time between 1859 and 1882, the year of his
death, Mr. Darwin bitterly regretted his initial error,
and would have been only too thankful to repair it,
but he could only put the difference between himself
and the early evolutionists clearly before his readers
at the cost of seeing his own system come tumbling
down like a pack of cards; this was more than he could
stand, so he buried his face, ostrich-like, in the
sand. I know no more pitiable figure in either
literature or science.
As I write these lines (July 1886)
I see a paragraph in Nature which I take it is intended
to convey the impression that Mr. Francis Darwin’s
life and letters of his father will appear shortly.
I can form no idea whether Mr. F. Darwin’s
forthcoming work is likely to appear before this present
volume; still less can I conjecture what it may or
may not contain; but I can give the reader a criterion
by which to test the good faith with which it is written.
If Mr. F. Darwin puts the distinctive feature that
differentiates Mr. C. Darwin from his predecessors
clearly before his readers, enabling them to seize
and carry it away with them once for all—if
he shows no desire to shirk this question, but, on
the contrary, faces it and throws light upon it, then
we shall know that his work is sincere, whatever its
shortcomings may be in other respects; and when people
are doing their best to help us and make us understand
all that they understand themselves, a great deal
may be forgiven them. If, on the other hand,
we find much talk about the wonderful light which
Mr. Charles Darwin threw on evolution by his theory
of natural selection, without any adequate attempt
to make us understand the difference between the natural
selection, say, of Mr. Patrick Matthew, and that of
his more famous successor, then we may know that we
are being trifled with; and that an attempt is being
again made to throw dust in our eyes.
