I shall perhaps best promote the acceptance
of the two main points on which I have been insisting
for some years past, I mean, the substantial identity
between heredity and memory, and the reintroduction
of design into organic development, by treating them
as if they had something of that physical life with
which they are so closely connected. Ideas are
like plants and animals in this respect also, as in
so many others, that they are more fully understood
when their relations to other ideas of their time,
and the history of their development are known and
borne in mind. By development I do not merely
mean their growth in the minds of those who first
advanced them, but that larger development which consists
in their subsequent good or evil fortunes—in
their reception, favourable or otherwise, by those
to whom they were presented. This is to an idea
what its surroundings are to an organism, and throws
much the same light upon it that knowledge of the conditions
under which an organism lives throws upon the organism
itself. I shall, therefore, begin this new work
with a few remarks about its predecessors.
I am aware that what I may say on
this head is likely to prove more interesting to future
students of the literature of descent than to my immediate
public, but any book that desires to see out a literary
three-score years and ten must offer something to future
generations as well as to its own. It is a condition
of its survival that it shall do this, and herein
lies one of the author’s chief difficulties.
If books only lived as long as men and women, we
should know better how to grow them; as matters stand,
however, the author lives for one or two generations,
whom he comes in the end to understand fairly well,
while the book, if reasonable pains have been taken
with it, should live more or less usefully for a dozen.
About the greater number of these generations the author
is in the dark; but come what may, some of them are
sure to have arrived at conclusions diametrically
opposed to our own upon every subject connected with
art, science, philosophy, and religion; it is plain,
therefore, that if posterity is to be pleased, it can
only be at the cost of repelling some present readers.
Unwilling as I am to do this, I still hold it the
lesser of two evils; I will be as brief, however,
as the interests of the opinions I am supporting will
allow.
In “Life and Habit” I
contended that heredity was a mode of memory.
I endeavoured to show that all hereditary traits, whether
of mind or body, are inherited in virtue of, and as
a manifestation of, the same power whereby we are
able to remember intelligently what we did half an
hour, yesterday, or a twelvemonth since, and this in
no figurative but in a perfectly real sense.
If life be compared to an equation of a hundred unknown
quantities, I followed Professor Hering of Prague
in reducing it to one of ninety-nine only, by showing
two of the supposed unknown quantities to be so closely
allied that they should count as one. I maintained
that instinct was inherited memory, and this without
admitting more exceptions and qualifying clauses than
arise, as it were, by way of harmonics from every
proposition, and must be neglected if thought and language
are to be possible.
I showed that if the view for which
I was contending was taken, many facts which, though
familiar, were still without explanation or connection
with our other ideas, would remain no longer isolated,
but be seen at once as joined with the mainland of
our most assured convictions. Among the things
thus brought more comfortably home to us was the principle
underlying longevity. It became apparent why
some living beings should live longer than others,
and how any race must be treated whose longevity it
is desired to increase. Hitherto we had known
that an elephant was a long-lived animal and a fly
short-lived, but we could give no reason why the one
should live longer than the other; that is to say,
it did not follow in immediate coherence with, or
as intimately associated with, any familiar principle
that an animal which is late in the full development
of its reproductive system will tend to live longer
than one which reproduces early. If the theory
of “Life and Habit” be admitted, the fact
of a slow-growing animal being in general longer lived
than a quick developer is seen to be connected with,
and to follow as a matter of course from, the fact
of our being able to remember anything at all, and
all the well-known traits of memory, as observed where
we can best take note of them, are perceived to be
reproduced with singular fidelity in the development
of an animal from its embryonic stages to maturity.
Take this view, and the very general
sterility of hybrids from being a CRUX of the theory
of descent becomes a stronghold of defence. It
appears as part of the same story as the benefit derived
from judicious, and the mischief from injudicious,
crossing; and this, in its turn, is seen as part of
the same story, as the good we get from change of
air and scene when we are overworked. I will
not amplify; but reversion to long-lost, or feral,
characteristics, the phenomena of old age, the fact
of the reproductive system being generally the last
to arrive at maturity—few further developments
occurring in any organism after this has been attained—the
sterility of many animals in confinement, the development
in both males and females under certain circumstances
of the characteristics of the opposite sex, the latency
of memory, the unconsciousness with which we grow,
and indeed perform all familiar actions, these points,
though hitherto, most of them, so apparently inexplicable
that no one even attempted to explain them, became
at once intelligible, if the contentions of “Life
and Habit” were admitted.
Before I had finished writing this
book I fell in with Professor Mivart’s “Genesis
of Species,” and for the first time understood
the distinction between the Lamarckian and Charles-Darwinian
systems of evolution. This had not, so far as
I then knew, been as yet made clear to us by any of
our more prominent writers upon the subject of descent
with modification; the distinction was unknown to the
general public, and indeed is only now beginning to
be widely understood. While reading Mr. Mivart’s
book, however, I became aware that I was being faced
by two facts, each incontrovertible, but each, if
its leading exponents were to be trusted, incompatible
with the other.
On the one hand there was descent;
we could not read Mr. Darwin’s books and doubt
that all, both animals and plants, were descended
from a common source. On the other, there was
design; we could not read Paley and refuse to admit
that design, intelligence, adaptation of means to
ends, must have had a large share in the development
of the life we saw around us; it seemed indisputable
that the minds and bodies of all living beings must
have come to be what they are through a wise ordering
and administering of their estates. We could
not, therefore, dispense either with descent or with
design, and yet it seemed impossible to keep both,
for those who offered us descent stuck to it that
we could have no design, and those, again, who spoke
so wisely and so well about design would not for a
moment hear of descent with modification.
Each, moreover, had a strong case.
Who could reflect upon rudimentary organs, and grant
Paley the kind of design that alone would content
him? And yet who could examine the foot or the
eye, and grant Mr. Darwin his denial of forethought
and plan?
For that Mr. Darwin did deny skill
and contrivance in connection with the greatly preponderating
part of organic developments cannot be and is not
now disputed. In the first chapter of “Evolution
Old and New” I brought forward passages to show
how completely he and his followers deny design, but
will here quote one of the latest of the many that
have appeared to the same effect since “Evolution
Old and New” was published; it is by Mr. Romanes,
and runs as follows:-
“It is the very essence
of the Darwinian hypothesis that it only seeks to
explain the apparently purposive variations, or
variations of an adaptive kind.” {17a}
The words “apparently purposive”
show that those organs in animals and plants which
at first sight seem to have been designed with a view
to the work they have to do—that is to say,
with a view to future function—had not,
according to Mr. Darwin, in reality any connection
with, or inception in, effort; effort involves purpose
and design; they had therefore no inception in design,
however much they might present the appearance of
being designed; the appearance was delusive; Mr. Romanes
correctly declares it to be “the very essence”
of Mr. Darwin’s system to attempt an explanation
of these seemingly purposive variations which shall
be compatible with their having arisen without being
in any way connected with intelligence or design.
As it is indisputable that Mr. Darwin
denied design, so neither can it be doubted that Paley
denied descent with modification. What, then,
were the wrong entries in these two sets of accounts,
on the detection and removal of which they would be
found to balance as they ought?
Paley’s weakest place, as already
implied, is in the matter of rudimentary organs; the
almost universal presence in the higher organisms
of useless, and sometimes even troublesome, organs
is fatal to the kind of design he is trying to uphold;
granted that there is design, still it cannot be so
final and far-foreseeing as he wishes to make it out.
Mr. Darwin’s weak place, on the other hand,
lies, firstly, in the supposition that because rudimentary
organs imply no purpose now, they could never in time
past have done so—that because they had
clearly not been designed with an eye to all circumstances
and all time, they never, therefore, could have been
designed with an eye to any time or any circumstances;
and, secondly, in maintaining that “accidental,”
“fortuitous,” “spontaneous”
variations could be accumulated at all except under
conditions that have never been fulfilled yet, and
never will be; in other words, his weak place lay
in the contention (for it comes to this) that there
can be sustained accumulation of bodily wealth, more
than of wealth of any other kind, unless sustained
experience, watchfulness, and good sense preside over
the accumulation. In “Life and Habit,”
following Mr. Mivart, and, as I now find, Mr. Herbert
Spencer, I showed (pp. 279-281) how impossible it was
for variations to accumulate unless they were for
the most part underlain by a sustained general principle;
but this subject will be touched upon more fully later
on.
The accumulation of accidental variations
which owed nothing to mind either in their inception,
or their accumulation, the pitchforking, in fact,
of mind out of the universe, or at any rate its exclusion
from all share worth talking about in the process of
organic development, this was the pill Mr. Darwin
had given us to swallow; but so thickly had he gilded
it with descent with modification, that we did as
we were told, swallowed it without a murmur, were lavish
in our expressions of gratitude, and, for some twenty
years or so, through the mouths of our leading biologists,
ordered design peremptorily out of court, if she so
much as dared to show herself. Indeed, we have
even given life pensions to some of the most notable
of these biologists, I suppose in order to reward them
for having hoodwinked us so much to our satisfaction.
Happily the old saying, Naturam expellas
furca, tamen usque recurret, still holds true, and
the reaction that has been gaining force for some
time will doubtless ere long brush aside the cobwebs
with which those who have a vested interest in Mr.
Darwin’s reputation as a philosopher still try
to fog our outlook. Professor Mivart was, as
I have said, among the first to awaken us to Mr. Darwin’s
denial of design, and to the absurdity involved therein.
He well showed how incredible Mr Darwin’s system
was found to be, as soon as it was fully realised,
but there he rather left us. He seemed to say
that we must have our descent and our design too, but
he did not show how we were to manage this with rudimentary
organs still staring us in the face. His work
rather led up to the clearer statement of the difficulty
than either put it before us in so many words, or
tried to remove it. Nevertheless there can be
no doubt that the “Genesis of Species”
gave Natural Selection what will prove sooner or later
to be its death-blow, in spite of the persistence
with which many still declare that it has received
no hurt, and the sixth edition of the” Origin
of Species,” published in the following year,
bore abundant traces of the fray. Moreover, though
Mr. Mivart gave us no overt aid, he pointed to the
source from which help might come, by expressly saying
that his most important objection to Neo-Darwinism
had no force against Lamarck.
To Lamarck, therefore, I naturally
turned, and soon saw that the theory on which I had
been insisting in” Life and Habit” was
in reality an easy corollary on his system, though
one which he does not appear to have caught sight
of. I saw also that his denial of design was
only, so to speak, skin deep, and that his system was
in reality teleological, inasmuch as, to use Isidore
Geoffroy’s words, it makes the organism design
itself. In making variations depend on changed
actions, and these, again, on changed views of life,
efforts, and designs, in consequence of changed conditions
of life, he in effect makes effort, intention, will,
all of which involve design (or at any rate which
taken together involve it), underlie progress in organic
development. True, he did not know he was a
teleologist, but he was none the less a teleologist
for this. He was an unconscious teleologist,
and as such perhaps more absolutely an upholder of
teleology than Paley himself; but this is neither
here nor there; our concern is not with what people
think about themselves, but with what their reasoning
makes it evident that they really hold.
How strange the irony that hides us
from ourselves! When Isidore Geoffroy said that
according to Lamarck organisms designed themselves,
{20a} and endorsed this, as to a great extent he did,
he still does not appear to have seen that either
he or Lamarck were in reality reintroducing design
into organism; he does not appear to have seen this
more than Lamarck himself had seen it, but, on the
contrary, like Lamarck, remained under the impression
that he was opposing teleology or purposiveness.
Of course in one sense he did oppose
it; so do we all, if the word design be taken to intend
a very far-foreseeing of minute details, a riding
out to meet trouble long before it comes, a provision
on academic principles for contingencies that are
little likely to arise. We can see no evidence
of any such design as this in nature, and much everywhere
that makes against it. There is no such improvidence
as over providence, and whatever theories we may form
about the origin and development of the universe, we
may be sure that it is not the work of one who is
unable to understand how anything can possibly go
right unless he sees to it himself. Nature works
departmentally and by way of leaving details to subordinates.
But though those who see nature thus do indeed deny
design of the prescient-from-all-eternity order, they
in no way impugn a method which is far more in accord
with all that we commonly think of as design.
A design which is as incredible as that a ewe should
give birth to a lion becomes of a piece with all that
we observe most frequently if it be regarded rather
as an aggregation of many small steps than as a single
large one. This principle is very simple, but
it seems rather difficult to understand. It has
taken several generations before people would admit
it as regards organism even after it was pointed out
to them, and those who saw it as regards organism
still failed to understand it as regards design; an
inexorable “Thus far shalt thou go and no farther”
barred them from fruition of the harvest they should
have been the first to reap. The very men who
most insisted that specific difference was the accumulation
of differences so minute as to be often hardly, if
at all, perceptible, could not see that the striking
and baffling phenomena of design in connection with
organism admitted of exactly the same solution as
the riddle of organic development, and should be seen
not as a result reached per saltum, but as an accumulation
of small steps or leaps in a given direction.
It was as though those who had insisted on the derivation
of all forms of the steam-engine from the common
kettle, and who saw that this stands in much the same
relations to the engines, we will say, of the Great
Eastern steamship as the amoeba to man, were to declare
that the Great Eastern engines were not designed at
all, on the ground that no one in the early kettle
days had foreseen so great a future development, and
were unable to understand that a piecemeal solvitur
ambulando design is more omnipresent, all-seeing,
and all-searching, and hence more truly in the strictest
sense design, than any speculative leap of fancy,
however bold and even at times successful.
From Lamarck I went on to Buffon and
Erasmus Darwin—better men both of them
than Lamarck, and treated by him much as he has himself
been treated by those who have come after him—and
found that the system of these three writers, if considered
rightly, and if the corollary that heredity is only
a mode of memory were added, would get us out of our
dilemma as regards descent and design, and enable us
to keep both. We could do this by making the
design manifested in organism more like the only design
of which we know anything, and therefore the only
design of which we ought to speak—I mean
our own.
Our own design is tentative, and neither
very far-foreseeing nor very retrospective; it is
a little of both, but much of neither; it is like
a comet with a little light in front of the nucleus
and a good deal more behind it, which ere long, however,
fades away into the darkness; it is of a kind that,
though a little wise before the event, is apt to be
much wiser after it, and to profit even by mischance
so long as the disaster is not an overwhelming one;
nevertheless, though it is so interwoven with luck,
there is no doubt about its being design; why, then,
should the design which must have attended organic
development be other than this? If the thing
that has been is the thing that also shall be, must
not the thing which is be that which also has been?
Was there anything in the phenomena of organic life
to militate against such a view of design as this?
Not only was there nothing, but this view made things
plain, as the connecting of heredity and memory had
already done, which till now had been without explanation.
Rudimentary organs were no longer a hindrance to
our acceptance of design, they became weighty arguments
in its favour.
I therefore wrote “Evolution
Old and New,” with the object partly of backing
up “Life and Habit,” and showing the easy
rider it admitted, partly to show how superior the
old view of descent had been to Mr. Darwin’s,
and partly to reintroduce design into organism.
I wrote “Life and Habit” to show that
our mental and bodily acquisitions were mainly stores
of memory: I wrote “Evolution Old and New”
to add that the memory must be a mindful and designing
memory.
I followed up these two books with
“Unconscious Memory,” the main object
of which was to show how Professor Hering of Prague
had treated the connection between memory and heredity;
to show, again, how substantial was the difference
between Von Hartmann and myself in spite of some little
superficial resemblance; to put forward a suggestion
as regards the physics of memory, and to meet the most
plausible objection which I have yet seen brought against
“Life and Habit.”
Since writing these three books I
have published nothing on the connection between heredity
and memory, except a few pages of remarks on Mr. Romanes’
“Mental Evolution in Animals” in my book,
{23a} from which I will draw whatever seems to be more
properly placed here. I have collected many
facts that make my case stronger, but am precluded
from publishing them by the reflection that it is
strong enough already. I have said enough in
“Life and Habit” to satisfy any who wish
to be satisfied, and those who wish to be dissatisfied
would probably fail to see the force of what I said,
no matter how long and seriously I held forth to them;
I believe, therefore, that I shall do well to keep
my facts for my own private reading and for that of
my executors.
I once saw a copy of “Life and
Habit” on Mr. Bogue’s counter, and was
told by the very obliging shopman that a customer had
just written something in it which I might like to
see. I said of course I should like to see,
and immediately taking the book read the following—which
it occurs to me that I am not justified in publishing.
What was written ran thus:-
“As a reminder of our pleasant
hours on the broad Atlantic, will Mr. —
please accept this book (which I think contains more
truth, and less evidence of it, than any other I have
met with) from his friend — ?”
I presume the gentleman had met with
the Bible—a work which lays itself open
to a somewhat similar comment. I was gratified,
however, at what I had read, and take this opportunity
of thanking the writer, an American, for having liked
my book. It was so plain he had been relieved
at not finding the case smothered to death in the
weight of its own evidences, that I resolved not to
forget the lesson his words had taught me.
The only writer in connection with
“Life and Habit” to whom I am anxious
to reply is Mr. Herbert Spencer, but before doing this
I will conclude the present chapter with a consideration
of some general complaints that have been so often
brought against me that it may be worth while to notice
them.
These general criticisms have resolved
themselves mainly into two.
Firstly, it is said that I ought not
to write about biology on the ground of my past career,
which my critics declare to have been purely literary.
I wish I might indulge a reasonable hope of one day
becoming a literary man; the expression is not a good
one, but there is no other in such common use, and
this must excuse it; if a man can be properly called
literary, he must have acquired the habit of reading
accurately, thinking attentively, and expressing himself
clearly. He must have endeavoured in all sorts
of ways to enlarge the range of his sympathies so
as to be able to put himself easily en rapport with
those whom he is studying, and those whom he is addressing.
If he cannot speak with tongues himself, he is the
interpreter of those who can—without whom
they might as well be silent. I wish I could
see more signs of literary culture among my scientific
opponents; I should find their books much more easy
and agreeable reading if I could; and then they tell
me to satirise the follies and abuses of the age,
just as if it was not this that I was doing in writing
about themselves.
What, I wonder, would they say if
I were to declare that they ought not to write books
at all, on the ground that their past career has been
too purely scientific to entitle them to a hearing?
They would reply with justice that I should not bring
vague general condemnations, but should quote examples
of their bad writing. I imagine that I have
done this more than once as regards a good many of
them, and I dare say I may do it again in the course
of this book; but though I must own to thinking that
the greater number of our scientific men write abominably,
I should not bring this against them if I believed
them to be doing their best to help us; many such
men we happily have, and doubtless always shall have,
but they are not those who push to the fore, and it
is these last who are most angry with me for writing
on the subjects I have chosen. They constantly
tell me that I am not a man of science; no one knows
this better than I do, and I am quite used to being
told it, but I am not used to being confronted with
the mistakes that I have made in matters of fact,
and trust that this experience is one which I may
continue to spare no pains in trying to avoid.
Nevertheless I again freely grant
that I am not a man of science. I have never
said I was. I was educated for the Church.
I was once inside the Linnean Society’s rooms,
but have no present wish to go there again; though
not a man of science, however, I have never affected
indifference to the facts and arguments which men of
science have made it their business to lay before us;
on the contrary, I have given the greater part of
my time to their consideration for several years past.
I should not, however, say this unless led to do
so by regard to the interests of theories which I
believe to be as nearly important as any theories can
be which do not directly involve money or bodily convenience.
The second complaint against me is
to the effect that I have made no original experiments,
but have taken all my facts at second hand. This
is true, but I do not see what it has to do with the
question. If the facts are sound, how can it
matter whether A or B collected them? If Professor
Huxley, for example, has made a series of valuable
original observations (not that I know of his having
done so), why am I to make them over again?
What are fact-collectors worth if the fact co-ordinators
may not rely upon them? It seems to me that
no one need do more than go to the best sources for
his facts, and tell his readers where he got them.
If I had had occasion for more facts I daresay I
should have taken the necessary steps to get hold
of them, but there was no difficulty on this score;
every text-book supplied me with all, and more than
all, I wanted; my complaint was that the facts which
Mr. Darwin supplied would not bear the construction
he tried to put upon them; I tried, therefore, to
make them bear another which seemed at once more sound
and more commodious; rightly or wrongly I set up as
a builder, not as a burner of bricks, and the complaint
so often brought against me of not having made experiments
is about as reasonable as complaint against an architect
on the score of his not having quarried with his own
hands a single one of the stones which he has used
in building. Let my opponents show that the
facts which they and I use in common are unsound,
or that I have misapplied them, and I will gladly
learn my mistake, but this has hardly, to my knowledge,
been attempted. To me it seems that the chief
difference between myself and some of my opponents
lies in this, that I take my facts from them with
acknowledgment, and they take their theories from me—
without.
One word more and I have done.
I should like to say that I do not return to the
connection between memory and heredity under the impression
that I shall do myself much good by doing so.
My own share in the matter was very small.
The theory that heredity is only a mode of memory
is not mine, but Professor Hering’s. He
wrote in 1870, and I not till 1877. I should
be only too glad if he would take his theory and follow
it up himself; assuredly he could do so much better
than I can; but with the exception of his one not
lengthy address published some fifteen or sixteen years
ago he has said nothing upon the subject, so far at
least as I have been able to ascertain; I tried hard
to draw him in 1880, but could get nothing out of
him. If, again, any of our more influential writers,
not a few of whom evidently think on this matter much
as I do, would eschew ambiguities and tell us what
they mean in plain language, I would let the matter
rest in their abler hands, but of this there does
not seem much chance at present.
I wish there was, for in spite of
the interest I have felt in working the theory out
and the information I have been able to collect while
doing so, I must confess that I have found it somewhat
of a white elephant. It has got me into the hottest
of hot water, made a literary Ishmael of me, lost
me friends whom I have been sorry to lose, cost me
a good deal of money, done everything to me, in fact,
which a good theory ought not to do. Still, as
it seems to have taken up with me, and no one else
is inclined to treat it fairly, I shall continue to
report its developments from time to time as long
as life and health are spared me. Moreover, Ishmaels
are not without their uses, and they are not a drug
in the market just now.
I may now go on to Mr. Spencer.
