“As this paper contains nothing which deserves the name either of
experiment or discovery, and as it is, in fact, destitute of every
species of merit, we should have allowed it to pass among the
multitude of those articles which must always find their way into the
collections of a society which is pledged to publish two or three
volumes every year. . . . We wish to raise our feeble voice against
innovations, that can have no other effect than to check the progress
of science, and renew all those wild phantoms of the imagination
which Bacon and Newton put to flight from her temple.”—_Opening
Paragraph of a Review of Dr. Young’s Bakerian Lecture_. _Edinburgh
Review_, _January_ 1803, p. 450.
“Young’s work was laid before the Royal society, and was made the
1801 Bakerian Lecture. But he was before his time. The second
number of the _Edinburgh Review_ contained an article levelled
against him by Henry (afterwards Lord) Brougham, and this was so
severe an attack that Young’s ideas were absolutely quenched for
fifteen years. Brougham was then only twenty-four years of age.
Young’s theory was reproduced in France by Fresnel. In our days it
is the accepted theory, and is found to explain all the phenomena of
light.”—_Times Report of a Lecture by Professor Tyndall on Light_,
_April_ 27, 1880.

Note
FOR many years a link in the chain of Samuel Butler’s biological works
has been missing. “Unconscious Memory” was originally published thirty
years ago, but for fully half that period it has been out of print, owing
to the destruction of a large number of the unbound sheets in a fire at
the premises of the printers some years ago. The present reprint comes,
I think, at a peculiarly fortunate moment, since the attention of the
general public has of late been drawn to Butler’s biological theories in
a marked manner by several distinguished men of science, notably by Dr.
Francis Darwin, who, in his presidential address to the British
Association in 1908, quoted from the translation of Hering’s address on
“Memory as a Universal Function of Original Matter,” which Butler
incorporated into “Unconscious Memory,” and spoke in the highest terms of
Butler himself. It is not necessary for me to do more than refer to the
changed attitude of scientific authorities with regard to Butler and his
theories, since Professor Marcus Hartog has most kindly consented to
contribute an introduction to the present edition of “Unconscious
Memory,” summarising Butler’s views upon biology, and defining his
position in the world of science. A word must be said as to the
controversy between Butler and Darwin, with which Chapter IV is
concerned. I have been told that in reissuing the book at all I am
committing a grievous error of taste, that the world is no longer
interested in these “old, unhappy far-off things and battles long ago,”
and that Butler himself, by refraining from republishing “Unconscious
Memory,” tacitly admitted that he wished the controversy to be consigned
to oblivion. This last suggestion, at any rate, has no foundation in
fact. Butler desired nothing less than that his vindication of himself
against what he considered unfair treatment should be forgotten. He
would have republished “Unconscious Memory” himself, had not the latter
years of his life been devoted to all-engrossing work in other fields.
In issuing the present edition I am fulfilling a wish that he expressed
to me shortly before his death.

Introduction
By Marcus Hartog, M.A., D.Sc., F.L.S., F.R.H.S.
IN reviewing Samuel Butler’s works, “Unconscious Memory” gives us an
invaluable lead; for it tells us (Chaps. II, III) how the author came to
write the Book of the Machines in “Erewhon” (1872), with its
foreshadowing of the later theory, “Life and Habit,” (1878), “Evolution,
Old and New” (1879), as well as “Unconscious Memory” (1880) itself. His
fourth book on biological theory was “Luck? or Cunning?” (1887). {0a}
Besides these books, his contributions to biology comprise several
essays: “Remarks on Romanes’ _Mental Evolution in Animals_, contained in
“Selections from Previous Works” (1884) incorporated into “Luck? or
Cunning,” “The Deadlock in Darwinism” (_Universal Review_, April-June,
1890), republished in the posthumous volume of “Essays on Life, Art, and
Science” (1904), and, finally, some of the “Extracts from the Notebooks
of the late Samuel Butler,” edited by Mr. H. Festing Jones, now in course
of publication in the _New Quarterly Review_.
* * * * *
Of all these, “LIFE AND HABIT” (1878) is the most important, the main
building to which the other writings are buttresses or, at most, annexes.
Its teaching has been summarised in “Unconscious Memory” in four main
principles: “(1) the oneness of personality between parent and offspring;
(2) memory on the part of the offspring of certain actions which it did
when in the persons of its forefathers; (3) the latency of that memory
until it is rekindled by a recurrence of the associated ideas; (4) the
unconsciousness with which habitual actions come to be performed.” To
these we must add a fifth: the purposiveness of the actions of living
beings, as of the machines which they make or select.
Butler tells (“Life and Habit,” p. 33) that he sometimes hoped “that this
book would be regarded as a valuable adjunct to Darwinism.” He was
bitterly disappointed in the event, for the book, as a whole, was
received by professional biologists as a gigantic joke—a joke, moreover,
not in the best possible taste. True, its central ideas, largely those
of Lamarck, had been presented by Hering in 1870 (as Butler found shortly
after his publication); they had been favourably received, developed by
Haeckel, expounded and praised by Ray Lankester. Coming from Butler,
they met with contumely, even from such men as Romanes, who, as Butler
had no difficulty in proving, were unconsciously inspired by the same
ideas—“_Nur mit ein bischen ander’n Wörter_.”
It is easy, looking back, to see why “Life and Habit” so missed its mark.
Charles Darwin’s presentation of the evolution theory had, for the first
time, rendered it possible for a “sound naturalist” to accept the
doctrine of common descent with divergence; and so given a real meaning
to the term “natural relationship,” which had forced itself upon the
older naturalists, despite their belief in special and independent
creations. The immediate aim of the naturalists of the day was now to
fill up the gaps in their knowledge, so as to strengthen the fabric of a
unified biology. For this purpose they found their actual scientific
equipment so inadequate that they were fully occupied in inventing fresh
technique, and working therewith at facts—save a few critics, such as St.
George Mivart, who was regarded as negligible, since he evidently held a
brief for a party standing outside the scientific world.
Butler introduced himself as what we now call “The Man in the Street,”
far too bare of scientific clothing to satisfy the Mrs. Grundy of the
domain: lacking all recognised tools of science and all sense of the
difficulties in his way, he proceeded to tackle the problems of science
with little save the deft pen of the literary expert in his hand. His
very failure to appreciate the difficulties gave greater power to his
work—much as Tartarin of Tarascon ascended the Jungfrau and faced
successfully all dangers of Alpine travel, so long as he believed them to
be the mere “blagues de réclame” of the wily Swiss host. His brilliant
qualities of style and irony themselves told heavily against him. Was he
not already known for having written the most trenchant satire that had
appeared since “Gulliver’s Travels”? Had he not sneered therein at the
very foundations of society, and followed up its success by a
pseudo-biography that had taken in the “Record” and the “Rock”? In “Life
and Habit,” at the very start, he goes out of his way to heap scorn at
the respected names of Marcus Aurelius, Lord Bacon, Goethe, Arnold of
Rugby, and Dr. W. B. Carpenter. He expressed the lowest opinion of the
Fellows of the Royal Society. To him the professional man of science,
with self-conscious knowledge for his ideal and aim, was a medicine-man,
priest, augur—useful, perhaps, in his way, but to be carefully watched by
all who value freedom of thought and person, lest with opportunity he
develop into a persecutor of the worst type. Not content with
blackguarding the audience to whom his work should most appeal, he went
on to depreciate that work itself and its author in his finest vein of
irony. Having argued that our best and highest knowledge is that of
whose possession we are most ignorant, he proceeds: “Above all, let no
unwary reader do me the injustice of believing in me. In that I write at
all I am among the damned.”
* * * * *
His writing of “EVOLUTION, OLD AND NEW” (1879) was due to his conviction
that scant justice had been done by Charles Darwin and Alfred Wallace and
their admirers to the pioneering work of Buffon, Erasmus Darwin, and
Lamarck. To repair this he gives a brilliant exposition of what seemed
to him the most valuable portion of their teachings on evolution. His
analysis of Buffon’s true meaning, veiled by the reticences due to the
conditions under which he wrote, is as masterly as the English in which
he develops it. His sense of wounded justice explains the vigorous
polemic which here, as in all his later writings, he carries to the
extreme.
As a matter of fact, he never realised Charles Darwin’s utter lack of
sympathetic understanding of the work of his French precursors, let alone
his own grandfather, Erasmus. Yet this practical ignorance, which to
Butler was so strange as to transcend belief, was altogether genuine, and
easy to realise when we recall the position of Natural Science in the
early thirties in Darwin’s student days at Cambridge, and for a decade or
two later. Catastropharianism was the tenet of the day: to the last it
commended itself to his Professors of Botany and Geology,—for whom Darwin
held the fervent allegiance of the Indian scholar, or _chela_, to his
_guru_. As Geikie has recently pointed out, it was only later, when
Lyell had shown that the breaks in the succession of the rocks were only
partial and local, without involving the universal catastrophes that
destroyed all life and rendered fresh creations thereof necessary, that
any general acceptance of a descent theory could be expected. We may be
very sure that Darwin must have received many solemn warnings against the
dangerous speculations of the “French Revolutionary School.” He himself
was far too busy at the time with the reception and assimilation of new
facts to be awake to the deeper interest of far-reaching theories.
It is the more unfortunate that Butler’s lack of appreciation on these
points should have led to the enormous proportion of bitter personal
controversy that we find in the remainder of his biological writings.
Possibly, as suggested by George Bernard Shaw, his acquaintance and
admirer, he was also swayed by philosophical resentment at that
banishment of mind from the organic universe, which was generally thought
to have been achieved by Charles Darwin’s theory. Still, we must
remember that this mindless view is not implicit in Charles Darwin’s
presentment of his own theory, nor was it accepted by him as it has been
by so many of his professed disciples.
* * * * *
“UNCONSCIOUS MEMORY” (1880).—We have already alluded to an anticipation
of Butler’s main theses. In 1870 Dr. Ewald Hering, one of the most
eminent physiologists of the day, Professor at Vienna, gave an Inaugural
Address to the Imperial Royal Academy of Sciences: “Das Gedächtniss als
allgemeine Funktion der organisirter Substanz” (“Memory as a Universal
Function of Organised Matter”). When “Life and Habit” was well advanced,
Francis Darwin, at the time a frequent visitor, called Butler’s attention
to this essay, which he himself only knew from an article in “Nature.”
Herein Professor E. Ray Lankester had referred to it with admiring
sympathy in connection with its further development by Haeckel in a
pamphlet entitled “Die Perigenese der Plastidule.” We may note, however,
that in his collected Essays, “The Advancement of Science” (1890), Sir
Ray Lankester, while including this Essay, inserts on the blank page
{0b}—we had almost written “the white sheet”—at the back of it an apology
for having ever advocated the possibility of the transmission of acquired
characters.
“Unconscious Memory” was largely written to show the relation of Butler’s
views to Hering’s, and contains an exquisitely written translation of the
Address. Hering does, indeed, anticipate Butler, and that in language
far more suitable to the persuasion of the scientific public. It
contains a subsidiary hypothesis that memory has for its mechanism
special vibrations of the protoplasm, and the acquired capacity to
respond to such vibrations once felt upon their repetition. I do not
think that the theory gains anything by the introduction of this even as
a mere formal hypothesis; and there is no evidence for its being anything
more. Butler, however, gives it a warm, nay, enthusiastic, reception in
Chapter V (Introduction to Professor Hering’s lecture), and in his notes
to the translation of the Address, which bulks so large in this book, but
points out that he was “not committed to this hypothesis, though inclined
to accept it on a _prima facie_ view.” Later on, as we shall see, he
attached more importance to it.
The Hering Address is followed in “Unconscious Memory” by translations of
selected passages from Von Hartmann’s “Philosophy of the Unconscious,”
and annotations to explain the difference from this personification of
“_The Unconscious_” as a mighty all-ruling, all-creating personality, and
his own scientific recognition of the great part played by _unconscious
processes_ in the region of mind and memory.
These are the essentials of the book as a contribution to biological
philosophy. The closing chapters contain a lucid statement of objections
to his theory as they might be put by a rigid necessitarian, and a
refutation of that interpretation as applied to human action.
But in the second chapter Butler states his recession from the strong
logical position he had hitherto developed in his writings from “Erewhon”
onwards; so far he had not only distinguished the living from the
non-living, but distinguished among the latter _machines_ or _tools_ from
_things at large_. {0c} Machines or tools are the external organs of
living beings, as organs are their internal machines: they are fashioned,
assembled, or selected by the beings for a purposes so they have a
_future purpose_, as well as a _past history_. “Things at large” have a
past history, but no purpose (so long as some being does not convert them
into tools and give them a purpose): Machines have a Why? as well as a
How?: “things at large” have a How? only.
In “Unconscious Memory” the allurements of unitary or monistic views have
gained the upper hand, and Butler writes (p. 23):—
“The only thing of which I am sure is, that the distinction between
the organic and inorganic is arbitrary; that it is more coherent with
our other ideas, and therefore more acceptable, to start with every
molecule as a living thing, and then deduce death as the breaking up
of an association or corporation, than to start with inanimate
molecules and smuggle life into them; and that, therefore, what we
call the inorganic world must be regarded as up to a certain point
living, and instinct, within certain limits, with consciousness,
volition, and power of concerted action. _It is only of late_,
_however_, _that I have come to this opinion_.”
I have italicised the last sentence, to show that Butler was more or less
conscious of its irreconcilability with much of his most characteristic
doctrine. Again, in the closing chapter, Butler writes (p. 275):—
“We should endeavour to see the so-called inorganic as living in
respect of the qualities it has in common with the organic, rather
than the organic as non-living in respect of the qualities it has in
common with the inorganic.”
We conclude our survey of this book by mentioning the literary
controversial part chiefly to be found in Chapter IV, but cropping up
elsewhere. It refers to interpolations made in the authorised
translation of Krause’s “Life of Erasmus Darwin.” Only one side is
presented; and we are not called upon, here or elsewhere, to discuss the
merits of the question.
* * * * *
“LUCK, OR CUNNING, as the Main Means of Organic Modification? an Attempt
to throw Additional Light upon the late Mr. Charles Darwin’s Theory of
Natural Selection” (1887), completes the series of biological books.
This is mainly a book of strenuous polemic. It brings out still more
forcibly the Hering-Butler doctrine of continued personality from
generation to generation, and of the working of unconscious memory
throughout; and points out that, while this is implicit in much of the
teaching of Herbert Spencer, Romanes, and others, it was nowhere—even
after the appearance of “Life and Habit”—explicitly recognised by them,
but, on the contrary, masked by inconsistent statements and teaching.
Not Luck but Cunning, not the uninspired weeding out by Natural Selection
but the intelligent striving of the organism, is at the bottom of the
useful variety of organic life. And the parallel is drawn that not the
happy accident of time and place, but the Machiavellian cunning of
Charles Darwin, succeeded in imposing, as entirely his own, on the
civilised world an uninspired and inadequate theory of evolution wherein
luck played the leading part; while the more inspired and inspiring views
of the older evolutionists had failed by the inferiority of their luck.
On this controversy I am bound to say that I do not in the very least
share Butler’s opinions; and I must ascribe them to his lack of personal
familiarity with the biologists of the day and their modes of thought and
of work. Butler everywhere undervalues the important work of elimination
played by Natural Selection in its widest sense.
The “Conclusion” of “Luck, or Cunning?” shows a strong advance in
monistic views, and a yet more marked development in the vibration
hypothesis of memory given by Hering and only adopted with the greatest
reserve in “Unconscious Memory.”
“Our conception, then, concerning the nature of any matter depends
solely upon its kind and degree of unrest, that is to say, on the
characteristics of the vibrations that are going on within it. The
exterior object vibrating in a certain way imparts some of its
vibrations to our brain; but if the state of the thing itself depends
upon its vibrations, it [the thing] must be considered as to all
intents and purposes the vibrations themselves—plus, of course, the
underlying substance that is vibrating. . . . The same vibrations,
therefore, form the substance remembered, introduce an infinitesimal
dose of it within the brain, modify the substance remembering, and,
in the course of time, create and further modify the mechanism of
both the sensory and the motor nerves. Thought and thing are one.
“I commend these two last speculations to the reader’s charitable
consideration, as feeling that I am here travelling beyond the ground
on which I can safely venture. . . . I believe they are both
substantially true.”
In 1885 he had written an abstract of these ideas in his notebooks (see
_New Quarterly Review_, 1910, p. 116), and as in “Luck, or Cunning?”
associated them vaguely with the unitary conceptions introduced into
chemistry by Newlands and Mendelejeff. Judging himself as an outsider,
the author of “Life and Habit” would certainly have considered the mild
expression of faith, “I believe they are both substantially true,”
equivalent to one of extreme doubt. Thus “the fact of the Archbishop’s
recognising this as among the number of his beliefs is conclusive
evidence, with those who have devoted attention to the laws of thought,
that his mind is not yet clear” on the matter of the belief avowed (see
“Life and Habit,” pp. 24, 25).
To sum up: Butler’s fundamental attitude to the vibration hypothesis was
all through that taken in “Unconscious Memory”; he played with it as a
pretty pet, and fancied it more and more as time went on; but instead of
backing it for all he was worth, like the main theses of “Life and
Habit,” he put a big stake on it—and then hedged.
* * * * *
The last of Butler’s biological writings is the Essay, “THE DEADLOCK IN
DARWINISM,” containing much valuable criticism on Wallace and Weismann.
It is in allusion to the misnomer of Wallace’s book, “Darwinism,” that he
introduces the term “Wallaceism” {0d} for a theory of descent that
excludes the transmission of acquired characters. This was, indeed, the
chief factor that led Charles Darwin to invent his hypothesis of
pangenesis, which, unacceptable as it has proved, had far more to
recommend it as a formal hypothesis than the equally formal germ-plasm
hypothesis of Weismann.
* * * * *
The chief difficulty in accepting the main theses of Butler and Hering is
one familiar to every biologist, and not at all difficult to understand
by the layman. Everyone knows that the complicated beings that we term
“Animals” and “Plants,” consist of a number of more or less
individualised units, the cells, each analogous to a simpler being, a
Protist—save in so far as the character of the cell unit of the Higher
being is modified in accordance with the part it plays in that complex
being as a whole. Most people, too, are familiar with the fact that the
complex being starts as a single cell, separated from its parent; or,
where bisexual reproduction occurs, from a cell due to the fusion of two
cells, each detached from its parent. Such cells are called
“Germ-cells.” The germ-cell, whether of single or of dual origin, starts
by dividing repeatedly, so as to form the _primary embryonic cells_, a
complex mass of cells, at first essentially similar, which, however, as
they go on multiplying, undergo differentiations and migrations, losing
their simplicity as they do so. Those cells that are modified to take
part in the proper work of the whole are called tissue-cells. In virtue
of their activities, their growth and reproductive power are limited—much
more in Animals than in Plants, in Higher than in Lower beings. It is
these tissues, or some of them, that receive the impressions from the
outside which leave the imprint of memory. Other cells, which may be
closely associated into a continuous organ, or more or less surrounded by
tissue-cells, whose part it is to nourish them, are called “secondary
embryonic cells,” or “germ-cells.” The germ-cells may be differentiated
in the young organism at a very early stage, but in Plants they are
separated at a much later date from the less isolated embryonic regions
that provide for the Plant’s branching; in all cases we find embryonic
and germ-cells screened from the life processes of the complex organism,
or taking no very obvious part in it, save to form new tissues or new
organs, notably in Plants.
Again, in ourselves, and to a greater or less extent in all Animals, we
find a system of special tissues set apart for the reception and storage
of impressions from the outer world, and for guiding the other organs in
their appropriate responses—the “Nervous System”; and when this system is
ill-developed or out of gear the remaining organs work badly from lack of
proper skilled guidance and co-ordination. How can we, then, speak of
“memory” in a germ-cell which has been screened from the experiences of
the organism, which is too simple in structure to realise them if it were
exposed to them? My own answer is that we cannot form any theory on the
subject, the only question is whether we have any right to _infer_ this
“memory” from the _behaviour_ of living beings; and Butler, like Hering,
Haeckel, and some more modern authors, has shown that the inference is a
very strong presumption. Again, it is easy to over-value such complex
instruments as we possess. The possessor of an up-to-date camera, well
instructed in the function and manipulation of every part, but ignorant
of all optics save a hand-to-mouth knowledge of the properties of his own
lens, might say that _a priori_ no picture could be taken with a
cigar-box perforated by a pin-hole; and our ignorance of the mechanism of
the Psychology of any organism is greater by many times than that of my
supposed photographer. We know that Plants are able to do many things
that can only be accounted for by ascribing to them a “psyche,” and these
co-ordinated enough to satisfy their needs; and yet they possess no
central organ comparable to the brain, no highly specialised system for
intercommunication like our nerve trunks and fibres. As Oscar Hertwig
says, we are as ignorant of the mechanism of the development of the
individual as we are of that of hereditary transmission of acquired
characters, and the absence of such mechanism in either case is no reason
for rejecting the proven fact.
However, the relations of germ and body just described led Jäger,
Nussbaum, Galton, Lankester, and, above all, Weismann, to the view that
the germ-cells or “stirp” (Galton) were _in_ the body, but not _of_ it.
Indeed, in the body and out of it, whether as reproductive cells set
free, or in the developing embryo, they are regarded as forming one
continuous homogeneity, in contrast to the differentiation of the body;
and it is to these cells, regarded as a continuum, that the terms stirp,
germ-plasm, are especially applied. Yet on this view, so eagerly
advocated by its supporters, we have to substitute for the hypothesis of
memory, which they declare to have no real meaning here, the far more
fantastic hypotheses of Weismann: by these they explain the process of
differentiation in the young embryo into new germ and body; and in the
young body the differentiation of its cells, each in due time and place,
into the varied tissue cells and organs. Such views might perhaps be
acceptable if it could be shown that over each cell-division there
presided a wise all-guiding genie of transcending intellect, to which
Clerk-Maxwell’s sorting demons were mere infants. Yet these views have
so enchanted many distinguished biologists, that in dealing with the
subject they have actually ignored the existence of equally able workers
who hesitate to share the extremest of their views. The phenomenon is
one well known in hypnotic practice. So long as the non-Weismannians
deal with matters outside this discussion, their existence and their work
is rated at its just value; but any work of theirs on this point so
affects the orthodox Weismannite (whether he accept this label or reject
it does not matter), that for the time being their existence and the good
work they have done are alike non-existent. {0e}
Butler founded no school, and wished to found none. He desired that what
was true in his work should prevail, and he looked forward calmly to the
time when the recognition of that truth and of his share in advancing it
should give him in the lives of others that immortality for which alone
he craved.
Lamarckian views have never lacked defenders here and in America. Of the
English, Herbert Spencer, who however, was averse to the vitalistic
attitude, Vines and Henslow among botanists, Cunningham among zoologists,
have always resisted Weismannism; but, I think, none of these was
distinctly influenced by Hering and Butler. In America the majority of
the great school of palæontologists have been strong Lamarckians, notably
Cope, who has pointed out, moreover, that the transformations of energy
in living beings are peculiar to them.
We have already adverted to Haeckel’s acceptance and development of
Hering’s ideas in his “Perigenese der Plastidule.” Oscar Hertwig has
been a consistent Lamarckian, like Yves Delage of the Sorbonne, and these
occupy pre-eminent positions not only as observers, but as discriminating
theorists and historians of the recent progress of biology. We may also
cite as a Lamarckian—of a sort—Felix Le Dantec, the leader of the
chemico-physical school of the present day.
But we must seek elsewhere for special attention to the points which
Butler regarded as the essentials of “Life and Habit.” In 1893 Henry P.
Orr, Professor of Biology in the University of Louisiana, published a
little book entitled “A Theory of Heredity.” Herein he insists on the
nervous control of the whole body, and on the transmission to the
reproductive cells of such stimuli, received by the body, as will guide
them on their path until they shall have acquired adequate experience of
their own in the new body they have formed. I have found the name of
neither Butler nor Hering, but the treatment is essentially on their
lines, and is both clear and interesting.
In 1896 I wrote an essay on “The Fundamental Principles of Heredity,”
primarily directed to the man in the street. This, after being held over
for more than a year by one leading review, was “declined with regret,”
and again after some weeks met the same fate from another editor. It
appeared in the pages of “Natural Science” for October, 1897, and in the
“Biologisches Centralblatt” for the same year. I reproduce its closing
paragraph:—
“This theory [Hering-Butler’s] has, indeed, a tentative character,
and lacks symmetrical completeness, but is the more welcome as not
aiming at the impossible. A whole series of phenomena in organic
beings are correlated under the term of _memory_, _conscious and
unconscious_, _patent and latent_. . . . Of the order of unconscious
memory, latent till the arrival of the appropriate stimulus, is all
the co-operative growth and work of the organism, including its
development from the reproductive cells. Concerning the _modus
operandi_ we know nothing: the phenomena may be due, as Hering
suggests, to molecular vibrations, which must be at least as distinct
from ordinary physical disturbances as Röntgen’s rays are from
ordinary light; or it may be correlated, as we ourselves are inclined
to think, with complex chemical changes in an intricate but orderly
succession. For the present, at least, the problem of heredity can
only be elucidated by the light of mental, and not material
processes.”
It will be seen that I express doubts as to the validity of Hering’s
invocation of molecular vibrations as the mechanism of memory, and
suggest as an alternative rhythmic chemical changes. This view has
recently been put forth in detail by J. J. Cunningham in his essay on the
“Hormone {0f} Theory of Heredity,” in the _Archiv für
Entwicklungsmechanik_ (1909), but I have failed to note any direct effect
of my essay on the trend of biological thought.
Among post-Darwinian controversies the one that has latterly assumed the
greatest prominence is that of the relative importance of small
variations in the way of more or less “fluctuations,” and of
“discontinuous variations,” or “mutations,” as De Vries has called them.
Darwin, in the first four editions of the “Origin of Species,” attached
more importance to the latter than in subsequent editions; he was swayed
in his attitude, as is well known, by an article of the physicist,
Fleeming Jenkin, which appeared in the _North British Review_. The
mathematics of this article were unimpeachable, but they were founded on
the assumption that exceptional variations would only occur in single
individuals, which is, indeed, often the case among those domesticated
races on which Darwin especially studied the phenomena of variation.
Darwin was no mathematician or physicist, and we are told in his
biography that he regarded every tool-shop rule or optician’s thermometer
as an instrument of precision: so he appears to have regarded Fleeming
Jenkin’s demonstration as a mathematical deduction which he was bound to
accept without criticism.
Mr. William Bateson, late Professor of Biology in the University of
Cambridge, as early as 1894 laid great stress on the importance of
discontinuous variations, collecting and collating the known facts in his
“Materials for the Study of Variations”; but this important work, now
become rare and valuable, at the time excited so little interest as to be
‘remaindered’ within a very few years after publication.
In 1901 Hugo De Vries, Professor of Botany in the University of
Amsterdam, published “Die Mutationstheorie,” wherein he showed that
mutations or discontinuous variations in various directions may appear
simultaneously in many individuals, and in various directions. In the
gardener’s phrase, the species may take to sporting in various directions
at the same time, and each sport may be represented by numerous
specimens.
De Vries shows the probability that species go on for long periods
showing only fluctuations, and then suddenly take to sporting in the way
described, short periods of mutation alternating with long intervals of
relative constancy. It is to mutations that De Vries and his school, as
well as Luther Burbank, the great former of new fruit- and flower-plants,
look for those variations which form the material of Natural Selection.
In “God the Known and God the Unknown,” which appeared in the _Examiner_
(May, June, and July), 1879, but though then revised was only published
posthumously in 1909, Butler anticipates this distinction:—
“Under these circumstances organism must act in one or other of these
two ways: it must either change slowly and continuously with the
surroundings, paying cash for everything, meeting the smallest change
with a corresponding modification, so far as is found convenient, or
it must put off change as long as possible, and then make larger and
more sweeping changes.
“Both these courses are the same in principle, the difference being
one of scale, and the one being a miniature of the other, as a ripple
is an Atlantic wave in little; both have their advantages and
disadvantages, so that most organisms will take the one course for
one set of things and the other for another. They will deal promptly
with things which they can get at easily, and which lie more upon the
surface; _those_, _however_, _which are more troublesome to reach_,
_and lie deeper_, _will be handled upon more cataclysmic principles_,
_being allowed longer periods of repose followed by short periods of
greater activity_ . . . it may be questioned whether what is called a
sport is not the organic expression of discontent which has been long
felt, but which has not been attended to, nor been met step by step
by as much small remedial modification as was found practicable: so
that when a change does come it comes by way of revolution. Or,
again (only that it comes to much the same thing), it may be compared
to one of those happy thoughts which sometimes come to us unbidden
after we have been thinking for a long time what to do, or how to
arrange our ideas, and have yet been unable to come to any
conclusion” (pp. 14, 15). {0g}
We come to another order of mind in Hans Driesch. At the time he began
his work biologists were largely busy in a region indicated by Darwin,
and roughly mapped out by Haeckel—that of phylogeny. From the facts of
development of the individual, from the comparison of fossils in
successive strata, they set to work at the construction of pedigrees, and
strove to bring into line the principles of classification with the more
or less hypothetical “stemtrees.” Driesch considered this futile, since
we never could reconstruct from such evidence anything certain in the
history of the past. He therefore asserted that a more complete
knowledge of the physics and chemistry of the organic world might give a
scientific explanation of the phenomena, and maintained that the proper
work of the biologist was to deepen our knowledge in these respects. He
embodied his views, seeking the explanation on this track, filling up
gaps and tracing projected roads along lines of probable truth in his
“Analytische Theorie der organische Entwicklung.” But his own work
convinced him of the hopelessness of the task he had undertaken, and he
has become as strenuous a vitalist as Butler. The most complete
statement of his present views is to be found in “The Philosophy of Life”
(1908–9), being the Giffold Lectures for 1907–8. Herein he postulates a
quality (“psychoid”) in all living beings, directing energy and matter
for the purpose of the organism, and to this he applies the Aristotelian
designation “Entelechy.” The question of the transmission of acquired
characters is regarded as doubtful, and he does not emphasise—if he
accepts—the doctrine of continuous personality. His early youthful
impatience with descent theories and hypotheses has, however,
disappeared.
* * * * *
In the next work the influence of Hering and Butler is definitely present
and recognised. In 1906 Signor Eugenio Rignano, an engineer keenly
interested in all branches of science, and a little later the founder of
the international review, _Rivistà di Scienza_ (now simply called
_Scientia_), published in French a volume entitled “Sur la
transmissibilité des Caractères acquis—Hypothèse d’un Centro-épigenèse.”
Into the details of the author’s work we will not enter fully. Suffice
it to know that he accepts the Hering-Butler theory, and makes a distinct
advance on Hering’s rather crude hypothesis of persistent vibrations by
suggesting that the remembering centres store slightly different forms of
energy, to give out energy of the same kind as they have received, like
electrical accumulators. The last chapter, “Le Phénomène mnémonique et
le Phénomène vital,” is frankly based on Hering.
In “The Lesson of Evolution” (1907, posthumous, and only published for
private circulation) Frederick Wollaston Hutton, F.R.S., late Professor
of Biology and Geology, first at Dunedin and after at Christchurch, New
Zealand, puts forward a strongly vitalistic view, and adopts Hering’s
teaching. After stating this he adds, “The same idea of heredity being
due to unconscious memory was advocated by Mr. Samuel Butler in his “Life
and Habit.”
Dr. James Mark Baldwin, Stuart Professor of Psychology in Princeton
University, U.S.A., called attention early in the 90’s to a reaction
characteristic of all living beings, which he terms the “Circular
Reaction.” We take his most recent account of this from his “Development
and Evolution” (1902):—{0h}
“The general fact is that the organism reacts by concentration upon
the locality stimulated for the _continuance_ of the conditions,
movements, stimulations, _which are vitally beneficial_, and for the
cessation of the conditions, movements, stimulations _which are
vitally depressing_.”
This amounts to saying in the terminology of Jenning (see below) that the
living organism alters its “physiological states” either for its direct
benefit, or for its indirect benefit in the reduction of harmful
conditions.
Again:—
“This form of concentration of energy on stimulated localities, with
the resulting renewal through movement of conditions that are
pleasure-giving and beneficial, and the consequent repetition of the
movements is called ‘circular reaction.’”
Of course, the inhibition of such movements as would be painful on
repetition is merely the negative case of the circular reaction. We must
not put too much of our own ideas into the author’s mind; he nowhere says
explicitly that the animal or plant shows its sense and does this because
it likes the one thing and wants it repeated, or dislikes the other and
stops its repetition, as Butler would have said. Baldwin is very strong
in insisting that no full explanation can be given of living processes,
any more than of history, on purely chemico-physical grounds.
The same view is put differently and independently by H. S. Jennings,
{0i} who started his investigations of living Protista, the simplest of
living beings, with the idea that only accurate and ample observation was
needed to enable us to explain all their activities on a mechanical
basis, and devised ingenious models of protoplastic movements. He was
led, like Driesch, to renounce such efforts as illusory, and has come to
the conviction that in the behaviour of these lowly beings there is a
purposive and a tentative character—a method of “trial and error”—that
can only be interpreted by the invocation of psychology. He points out
that after stimulation the “state” of the organism may be altered, so
that the response to the same stimulus on repetition is other. Or, as he
puts it, the first stimulus has caused the organism to pass into a new
“physiological state.” As the change of state from what we may call the
“primary indifferent state” is advantageous to the organism, we may
regard this as equivalent to the doctrine of the “circular reaction,” and
also as containing the essence of Semon’s doctrine of “engrams” or
imprints which we are about to consider. We cite one passage which for
audacity of thought (underlying, it is true, most guarded expression) may
well compare with many of the boldest flights in “Life and Habit”:—
“It may be noted that regulation in the manner we have set forth is
what, in the behaviour of higher organisms, at least, is called
intelligence [the examples have been taken from Protista, Corals, and
the Lowest Worms]. If the same method of regulation is found in
other fields, there is no reason for refusing to compare the action
to intelligence. Comparison of the regulatory processes that are
shown in internal physiological changes and in regeneration to
intelligence seems to be looked upon sometimes as heretical and
unscientific. Yet intelligence is a name applied to processes that
actually exist in the regulation of movements, and there is, _a
priori_, no reason why similar processes should not occur in
regulation in other fields. When we analyse regulation objectively
there seems indeed reason to think that the processes are of the same
character in behaviour as elsewhere. If the term intelligence be
reserved for the subjective accompaniments of such regulation, then
of course we have no direct knowledge of its existence in any of the
fields of regulation outside of the self, and in the self perhaps
only in behaviour. But in a purely objective consideration there
seems no reason to suppose that regulation in behaviour
(intelligence) is of a fundamentally different character from
regulation elsewhere.” (“Method of Regulation,” p. 492.)
Jennings makes no mention of questions of the theory of heredity. He has
made some experiments on the transmission of an acquired character in
Protozoa; but it was a mutilation-character, which is, as has been often
shown, {0j} not to the point.

One of the most obvious criticisms of Hering’s exposition is based upon
the extended use he makes of the word “Memory”: this he had foreseen and
deprecated.
“We have a perfect right,” he says, “to extend our conception of
memory so as to make it embrace involuntary [and also unconscious]
reproductions of sensations, ideas, perceptions, and efforts; but we
find, on having done so, that we have so far enlarged her boundaries
that she proves to be an ultimate and original power, the source and,
at the same time, the unifying bond, of our whole conscious life.”
(“Unconscious Memory,” p. 68.)
This sentence, coupled with Hering’s omission to give to the concept of
memory so enlarged a new name, clear alike of the limitations and of the
stains of habitual use, may well have been the inspiration of the next
work on our list. Richard Semon is a professional zoologist and
anthropologist of such high status for his original observations and
researches in the mere technical sense, that in these countries he would
assuredly have been acclaimed as one of the Fellows of the Royal Society
who were Samuel Butler’s special aversion. The full title of his book is
“DIE MNEME als erhaltende Prinzip im Wechsel des organischen Geschehens”
(Munich, Ed. 1, 1904; Ed. 2, 1908). We may translate it “MNEME, a
Principle of Conservation in the Transformations of Organic Existence.”
From this I quote in free translation the opening passage of Chapter II:—
“We have shown that in very many cases, whether in Protist, Plant, or
Animal, when an organism has passed into an indifferent state after
the reaction to a stimulus has ceased, its irritable substance has
suffered a lasting change: I call this after-action of the stimulus
its ‘imprint’ or ‘engraphic’ action, since it penetrates and imprints
itself in the organic substance; and I term the change so effected an
‘imprint’ or ‘engram’ of the stimulus; and the sum of all the
imprints possessed by the organism may be called its ‘store of
imprints,’ wherein we must distinguish between those which it has
inherited from its forbears and those which it has acquired itself.
Any phenomenon displayed by an organism as the result either of a
single imprint or of a sum of them, I term a ‘mnemic phenomenon’; and
the mnemic possibilities of an organism may be termed, collectively,
its ‘MNEME.’
“I have selected my own terms for the concepts that I have just
defined. On many grounds I refrain from making any use of the good
German terms ‘Gedächtniss, Erinnerungsbild.’ The first and chiefest
ground is that for my purpose I should have to employ the German
words in a much wider sense than what they usually convey, and thus
leave the door open to countless misunderstandings and idle
controversies. It would, indeed, even amount to an error of fact to
give to the wider concept the name already current in the narrower
sense—nay, actually limited, like ‘Erinnerungsbild,’ to phenomena of
consciousness. . . . In Animals, during the course of history, one
set of organs has, so to speak, specialised itself for the reception
and transmission of stimuli—the Nervous System. But from this
specialisation we are not justified in ascribing to the nervous
system any monopoly of the function, even when it is as highly
developed as in Man. . . . Just as the direct excitability of the
nervous system has progressed in the history of the race, so has its
capacity for receiving imprints; but neither susceptibility nor
retentiveness is its monopoly; and, indeed, retentiveness seems
inseparable from susceptibility in living matter.”
Semen here takes the instance of stimulus and imprint actions affecting
the nervous system of a dog
“who has up till now never experienced aught but kindness from the
Lord of Creation, and then one day that he is out alone is pelted
with stones by a boy. . . . Here he is affected at once by two sets
of stimuli: (1) the optic stimulus of seeing the boy stoop for stones
and throw them, and (2) the skin stimulus of the pain felt when they
hit him. Here both stimuli leave their imprints; and the organism is
permanently changed in relation to the recurrence of the stimuli.
Hitherto the sight of a human figure quickly stooping had produced no
constant special reaction. Now the reaction is constant, and may
remain so till death. . . . The dog tucks in its tail between its
legs and takes flight, often with a howl [as of] pain.”
“Here we gain on one side a deeper insight into the imprint action of
stimuli. It reposes on the lasting change in the conditions of the
living matter, so that the repetition of the immediate or synchronous
reaction to its first stimulus (in this case the stooping of the boy,
the flying stones, and the pain on the ribs), no longer demands, as
in the original state of indifference, the full stimulus _a_, but may
be called forth by a partial or different stimulus, _b_ (in this case
the mere stooping to the ground). I term the influences by which
such changed reaction are rendered possible, ‘outcome-reactions,’ and
when such influences assume the form of stimuli, ‘outcome-stimuli.’”
They are termed “outcome” (“ecphoria”) stimuli, because the author
regards them and would have us regard them as the outcome, manifestation,
or efference of an imprint of a previous stimulus. We have noted that
the imprint is equivalent to the changed “physiological state” of
Jennings. Again, the capacity for gaining imprints and revealing them by
outcomes favourable to the individual is the “circular reaction” of
Baldwin, but Semon gives no reference to either author. {0k}
In the preface to his first edition (reprinted in the second) Semon
writes, after discussing the work of Hering and Haeckel:—
“The problem received a more detailed treatment in Samuel Butler’s
book, ‘Life and Habit,’ published in 1878. Though he only made
acquaintance with Hering’s essay after this publication, Butler gave
what was in many respects a more detailed view of the coincidences of
these different phenomena of organic reproduction than did Hering.
With much that is untenable, Butler’s writings present many a
brilliant idea; yet, on the whole, they are rather a retrogression
than an advance upon Hering. Evidently they failed to exercise any
marked influence upon the literature of the day.”
This judgment needs a little examination. Butler claimed, justly, that
his “Life and Habit” was an advance on Hering in its dealing with
questions of hybridity, and of longevity puberty and sterility. Since
Semon’s extended treatment of the phenomena of crosses might almost be
regarded as the rewriting of the corresponding section of “Life and
Habit” in the “Mneme” terminology, we may infer that this view of the
question was one of Butler’s “brilliant ideas.” That Butler shrank from
accepting such a formal explanation of memory as Hering did with his
hypothesis should certainly be counted as a distinct “advance upon
Hering,” for Semon also avoids any attempt at an explanation of “Mneme.”
I think, however, we may gather the real meaning of Semon’s strictures
from the following passages:—
“I refrain here from a discussion of the development of this theory
of Lamarck’s by those Neo-Lamarckians who would ascribe to the
individual elementary organism an equipment of complex psychical
powers—so to say, anthropomorphic perception and volitions. This
treatment is no longer directed by the scientific principle of
referring complex phenomena to simpler laws, of deducing even human
intellect and will from simpler elements. On the contrary, they
follow that most abhorrent method of taking the most complex and
unresolved as a datum, and employing it as an explanation. The
adoption of such a method, as formerly by Samuel Butler, and recently
by Pauly, I regard as a big and dangerous step backward” (ed. 2, pp.
380–1, note).
Thus Butler’s alleged retrogressions belong to the same order of thinking
that we have seen shared by Driesch, Baldwin, and Jennings, and most
explicitly avowed, as we shall see, by Francis Darwin. Semon makes one
rather candid admission, “The impossibility of interpreting the phenomena
of physiological stimulation by those of direct reaction, and the
undeception of those who had put faith in this being possible, have led
many on the _backward path of vitalism_.” Semon assuredly will never be
able to complete his theory of “Mneme” until, guided by the experience of
Jennings and Driesch, he forsakes the blind alley of mechanisticism and
retraces his steps to reasonable vitalism.

But the most notable publications bearing on our matter are incidental to
the Darwin Celebrations of 1908–9. Dr. Francis Darwin, son,
collaborator, and biographer of Charles Darwin, was selected to preside
over the Meeting of the British Association held in Dublin in 1908, the
jubilee of the first publications on Natural Selection by his father and
Alfred Russel Wallace. In this address we find the theory of Hering,
Butler, Rignano, and Semon taking its proper place as a _vera causa_ of
that variation which Natural Selection must find before it can act, and
recognised as the basis of a rational theory of the development of the
individual and of the race. The organism is essentially purposive: the
impossibility of devising any adequate accounts of organic form and
function without taking account of the psychical side is most strenuously
asserted. And with our regret that past misunderstandings should be so
