ORGANIC NATURE’S RIDDLE.
BY ST. GEORGE MIVART.
II.
A thoroughly mechanical conception of nature is the scientific
ideal of a very large and a very influential school of thinkers.24
and the goal towards which they strive. In so striving they
follow the lead of the earliest of modern philosophers,
Descartes, who would probably have felt no small satisfaction
could he have foreseen that the doctrine of animal automatism
would be so eloquently advocated in the nineteenth century, as
well as that of a mechanical evolution of new species of animals
and plants.
Evidently the last-mentioned conception was necessary to
render the mechanical theory complete. As long as men
believed in the action of any mysterious intelligence hidden in
nature, and working through it in specific evolution towards
foreseen and intended ends, a mechanical conception of nature
was obviously impossible. But no less impossible was the
acceptance of such a mechanical hypothesis as long as any
belief remained in the existence, in individual animals, of an
innate and mysterious instinctive power directing their actions in
ways beneficial to them or to their race, yet unintended and
unforeseen by the creatures which performed those actions. A
denial of the existence of any true “instinct,” as well as of any
unmechanical action in specific evolution, was then necessary
for the maintenance of the mechanical theory, and accordingly
such denials have been confidently made, as we have already
seen.
While, however, this current of thought has been gaining in
volume and velocity, another contrary current has no less made
itself manifest, and amongst its exponents Edward Von
Hartmann25 is an eloquent advocate of the manifest action of
intelligence in nature, and of what may thus be called an
“intellectual” as opposed to a “mechanical” conception of the
universe. He lays much stress upon instinct, and is as earnest in
asserting its distinct existence and nature, as are the
mechanicians in denying its existence.
As was said at the beginning of the former article, the great
interest just now of the study of instinct, lies in its bearings on
the Darwinian hypothesis, or rather on the philosophy therewith
connected. Let us then proceed to examine whether or not the
analogies before pointed out between instinct and other forms
of vital activity can be carried further. Let us especially examine
whether the consideration of instinct in the widest sense of that
term, throws any glimmerings of light upon that most recondite
and still most mysterious process, the genesis of new species.
We may be encouraged to hope that such a result is possible
from the words of one of those twin biologists who on the same
night put forth their independently-arrived-at views as to what
we are all agreed to regard as at least an important factor in the
origin of species. No less a person than Mr. Wallace has written
the following significant words:—
“No thoughtful person can contemplate without amazement the
phenomena presented by the development of animals. We see
the most diverse forms—a mollusk, a frog, and a mammal—
arising from apparently identical primitive cells, and progressing
for a time by very similar initial changes, but thereafter each
pursuing its highly complex and often circuitous course of
development with unerring certainty, by means of laws and
forces of which we are totally ignorant. It is surely a not
improbable supposition that the unknown power which
determines and regulates this marvellous process may also
determine the initiation of these more important changes of
structure, and those developments of new parts and organs
which characterise the successive stages of the evolutions of
animal forms.”
These words advocate and confirm what I have elsewhere
antecedently urged. Many influences doubtless may come into
play in the origin of new species; but let us look a little narrowly
at certain influences which must come into play therein, and the
action of which no man can deny.
One of these influences (which no one has more richly
illustrated than has the late Mr. Darwin) is that of heredity; but
what is heredity?
In the first place it is obviously a property, not of new
individuals, not of offspring, but of parental forms. As every one
knows, it is the innate tendency which each organism possesses
to reproduce its like. If any living creature, x, was self-
impregnating and the outcome of a long line of self-
impregnating predecessors, all existing in the midst of one
uniform and continuously unvarying environment, then x would
produce offspring completely like itself. This fundamental
biological law of reproduction may be compared with the
physical first law of motion, according to which any body in
motion will continue to move on uniformly at the same rate and
in the same direction until some other force or motion is
impressed upon it.
The fact that new individual organisms arise from both a
paternal and a maternal influence, and from a line of ancestors
every one of which had a similar bifold origin, modifies this first
law of heredity only so far as to produce a more or less complex
compound of hereditary reproductive tendencies in every
individual, the effect of which must be analogous to that
mechanical law of the composition of forces resulting in the
production of a new creature resembling its immediate and
more remote progenitors in varying degrees, according to (1)
the amount of force springing from each ancestral strain, and
(2) the compatibility or incompatibility26 of the prevailing
tendencies, resulting in an intensification, perpetuation,
modification, or neutralisation of ancestral characters, as the
case may be.
All such action is but “heredity” acting in one or other mode; but
there is another and fundamentally different action which has to
be considered, and that is the action of the environment upon
nascent organisms—an action exercised either directly upon
them, or indirectly upon them through its direct action upon
their parents. That such actions produce unmistakable effects is
notorious. It will be, I think, sufficient here to advert to such
cases as the well-known brood-mare covered by a quagga, and
the peculiar effects of a well-bred bitch being lined by a
mongrel. These show how an action exercised upon the female
parent (but with no direct action on the immediate offspring)
may act indirectly upon her subsequent progeny.
As a rule, modifications accidentally or artificially induced in
parents are not transmitted to their offspring, as is well shown
by the need of the repetition of circumcision, and of pressure of
Indian children’s heads and Chinese girls’ feet, in each
generation. Yet there is good evidence that such changes are
occasionally inherited. The epileptic offspring of injured guinea-
pigs is a case often referred to. Haëckel speaks of a bull which
had lost its tail by accident, and which begot entirely tailless
calves. With respect to cats,27 I am indebted to Mr. John Birkett
for the knowledge of an instance in which a female with an
injured tail produced some stump-tailed kittens in two litters.
There is evidence that certain variations are more apt to be
inherited than others. Amongst those very apt to be inherited
are skin affections, affections of the nervous system and of the
generative organs, e.g. hypospadias and absence of the uterus.
The last case is one especially interesting, because it can only
be propagated indirectly.
Changes in the environment notoriously produce changes in
certain cases, even in adults. The modifications which may
result from the action of unusual agencies on the embryo have
been well shown by M. C. Dareste.28 As has been already
remarked, processes of repair take place the more readily the
younger the age of the subject. Similarly, it is probable that the
action of the environment generally acts more promptly and
intensely on the embryo than in the older young. That the same
organism will sometimes assume very different forms has been
observed by Professor Lankester in the case of Bacterium
rufescens.29
The effects of changed conditions is often very striking. Ficus
stipulata grown on a wall has small, thin leaves, and clings to
the surface like a large moss or a miniature ivy. Planted out, it
forms a shrub, with large, coarse, leathery leaves.
Mr. Wallace has pointed out some of the curious direct effects of
external conditions on organisms. He tells us30 that in the small
island of Amboina the butterflies (twelve species, of nine
different genera) are larger than those of any of the more
considerable islands about it, and that this is an effect probably
due to some local influence. In Celebes a whole series of
butterflies are not only of a larger size, but have the same
peculiar form of wing. The Duke of York’s Island seems, he tells
us, to have a tendency to make birds and insects white, or at
least pale, and the Philippines to develop metallic colors; while
the Moluccas and New Guinea seem to favor blackness and
redness in parrots and pigeons. Species of butterflies which in
India are provided with a tail to the wing, begin to lose that
appendage in the islands, and retain no trace of it on the
borders of the Pacific. The Æneas group of papilios never have
tails in the equatorial region of the Amazon Valley, but gradually
acquire tails, in many cases, as they range towards the northern
and southern tropics. Mr. Gould says that birds are more highly
colored under a clear atmosphere than in islands or on coasts—
a condition which also seems to affect insects, while it is
notorious that many shore plants have fleshy leaves. We need
but refer to the English oysters mentioned by Costa, which,
when transported to the Mediterranean, grew rapidly like the
true Mediterranean oyster, and to the twenty different kinds of
American trees said by Mr. Meehan to differ in the same manner
from their nearest American allies, as well as to the dogs, cats,
and rabbits which have been proved to undergo modifications
directly induced by climatic change. But still more strange and
striking changes have been recorded as due to external
conditions. Thus it is said31 that certain branchiopodous
creatures of the crab and lobster class (certain crustacea) have
been changed from the form characteristic of one genus
(Artemia salina) into that of quite another (Branchipus), by
having been introduced in large numbers by accident into very
salt water. The latter form is not only larger than the former, but
has an additional abdominal segment and a differently formed
tail. Such changes tell strongly in favor of the existence in
creatures of positive, innate tendencies to change in definite
directions under special conditions.
It is also obvious that the very same influences (e.g. amounts of
light, heat, moisture, &c.) will produce different effects in
different species, as also that the nature of some species is
more stubborn and less prone to variation than that of others.
Such, for example, is the case with the ass, the guinea-fowl,
and the goose, as compared with the dog, the horse, the
domestic fowl, and the pigeon. Thus both the amount and the
kind of variability differ in different races, and such
constitutional capacities or incapacities tend to be inherited by
their derivative forms, and so every kind of animal must have its
own inherent powers of modifiability or resistance, so that no
organism or race of organisms can vary in an absolutely
indefinite manner; and if so, then unlimited variability must be a
thing absolutely impossible.
The foregoing considerations tend to show that every variation
is a function32 of “heredity” and “external influence”—i.e. is the
result of the reaction of the special nature of each organism
upon the stimuli of its environment.
In addition to the action of heredity and the action of the
environment, there is also a peculiar kind of action due to an
internal force which has brought about so many interesting
cases of what is called “serial and lateral homology” which
cannot be due to descent, but which demonstrate the existence
of an intra-organic activity, the laws of which have yet to be
investigated. Comparative anatomy, pathology, and teratology
combine to point out the action of this internal force.
“Lateral homology” refers to the production of similar structures
on either side of the body, as in the similarity of our right and
left hands and feet. “Serial homology” refers to the production
of similar structures one behind the other, as in the series of
similar segments in the body of a worm or a centipede, and the
similar series of limbs in the latter animal.
These tendencies to lateral and serial repetition show
themselves in ways which cannot be accounted for by
inheritance from ancestral forms, but loudly proclaim the
presence and action of some internal force tending to produce
such homologous repetitions in organisms in different animals.
Thus even in ourselves, when we compare our leg and foot with
our arm and hand, we find that they have homologous features
which cannot be accounted for as being inheritances from
supposed ancestral animals. Our extremities resemble each
other in the texture of the skin, the shape of the nails, and
other points, and these resemblances are not due to external
conditions, but exist in spite of them; and comparative anatomy
reveals to us countless similar examples in the animal kingdom.
Limbs can hardly be more unlike in form and position than are
the arms and legs of birds, and yet we meet with breeds of
fowls and pigeons the feet of which are furnished with what are
called “boots,” that is, with long feathers which grow on the side
of the foot, serially corresponding with that of the hand, which
grow the feathers of the wing.
Again, in disease, and in cases of monstrosity or congenital
malformation, nothing is more common than to find precisely
similarly diseased conditions, or similar abnormalities of
structure, affecting serially or laterally homologous parts, such
as corresponding parts of the two arms or two legs, or of the
right (or left) arm and hand and leg and foot respectively.
Altogether it seems then to be undeniable that the characters
and the variations of species33 are due to the combined action
of internal and external agencies acting in a direct, positive, and
constructive manner.
It is obvious, however, that no character very prejudicial to a
species could ever be established, owing to the perpetual action
of all the destructive forces of nature which destructive forces,
considered as one whole, have been personified under the
name “natural selection.”
Its action, of course, is, and must be, destructive and negative.
The evolution of a new species is as necessarily a process which
is constructive and positive, and, as all must admit, is one due
to those variations upon which natural selection acts. Variation,
which thus lies at the origin of every new species, is (as we
have seen) the reaction of the nature of the varying animal
upon all the multitudinous agencies which environ it. Thus “the
nature of the animal” must be taken as the cause, “the
environment” being the stimulus which sets that cause in action,
and “natural selection” the agency which restrains it within the
bounds of physiological propriety.
We may compare the production of a new species to the
production of a statue. We have (1) the marble material
responding to the matter of the organism; (2) the intelligent
active force of the sculptor, directing his arm, responding to the
psychic nature of the organism, which reacts according to law
as surely as in the case of reflex action in healing, or in any
other vital action; (3) the various conceptions of the artist,
which stimulate him to model, responding to the environing
agencies which evoke variation; and (4) the blows of the
smiting chisel, corresponding to the action of natural selection.
No one would call the mere blows of the chisel—apart from both
the active force of the artist and the ideal conceptions which
direct that force—the cause of the production of the statue.
They are a cause—they help to produce it and are absolutely
necessary for its production. They are a material cause, but not
the primary cause. This distinction runs through all spheres of
activity. Thus the inadequacy of “natural selection” to explain
the origin of species runs parallel with its inadequacy to explain
the origin of instinct, as before pointed out.
The formal discoverer of a new fossil is the naturalist who first
sees it with an instructed eye, appreciates and describes it, not
the laborer who accidentally uncovers but ignores it, and who
cannot be accounted to be, any more than the spade he
handles, other than a mere material cause of its discovery. So
we must regard the sum of the destructive agencies of nature,
as a material cause of the origin of new species, their formal
cause being the reaction of the nature of their parent organisms
upon the sum of the multitudinous influences of their
environment. This kind of action of “the organism”—this formal
cause—has been compared by Mr. Alfred Wallace, and by me,
with the action of the organism in its embryonic development;
and this, I have further urged, is to be likened to the processes
of repair and reproduction of parts of the individual after injury,
and this, again, to reflex action, and, finally, this last to instinct
as manifested in ourselves and in other animals also.
The phenomena, then, exhibited in the various processes which
have been passed in review—nutrition, growth, repair, reflex
action, instinct, the evolution of the individual and of the species
—will, I think, abundantly serve to convince him who carefully
considers them, that a mechanical conception of nature is
inadequate and untenable. For it cannot be denied that in all
these various natural processes, performed by creatures devoid
of self-conscious intellect, there is somehow and somewhere a
latent rationality, by the imminent existence of which their
various admirably calculated activities are alone explicable. We
are compelled to admit that the merely animal and vegetable
worlds which we regard as irrational, possess a certain
rationality. This innate mysterious rationality blindly executes the
most elaborately contrived actions in order to effect necessary
or useful ends not consciously in view. We have here to consider
the question, “How is this blind rationality, this practical but
unconscious intelligence, explicable?”
Edward Von Hartmann, the eloquent prophet of the unconscious
intelligence of nature, teaches us that such intelligence is the
attribute of the very animals and plants themselves.
But can we limit the manifestations of intelligence and quasi-
instinctive purpose to the organic world? By no means. The
phenomena of crystallisation, the repair in due form of the
broken angle of a crystal, the inherent tendencies of chemical
substances to combine in definite proportions, and other laws of
the inorganic world, speak to us of unconscious intelligence and
volition latent in it also.
A perception of this truth has led to the conception of the
universal presence of true intelligence, as it were in a
rudimentary form, throughout the whole material universe—the
universal diffusion of what the late Professor Clifford called
“mind-stuff” in every particle of matter.
Such a belief can, however, be entertained only by those who
neglect to note the differences of objects presented to the
senses, attending solely to their resemblances, and describing
them by inadequate and misleading terms. The habit of
perverting language in this manner, has been lately well spoken
of as using intellectual false coin. By such an abuse of language
and disregard of points of unlikeness, all diversities may easily
be reduced to identity. Against such abuse the scientific biologist
must energetically protest. The expression “life” refers to
definite phenomena which are not found but in animals and
plants. The crystal is not really alive, because it does not
undergo the cycle of changes characteristic of life. It does not
sustain itself by alimentation, reproduce its kind, and die.
Anyone choosing to stretch terms may say that molecules of
inorganic matter live, because molecules exist. But in that case
we shall have to create a new term to denote what we now call
life. We might as well say a lamp-post “feels” because we can
make an impression on it, or that crystals “calculate” because of
their geometrical proportions, or that oxygen “lusts” after that
which it rusts. As the late Mr. G. H. Lewes has said: “We deny
that a crystal has sensibility; we deny it on the ground that
crystals exhibit no more signs of sensibility than plants exhibit
signs of civilisation, and we deny it on the ground that among
the conditions of sensibility there are some positively known to
us, and these are demonstrably absent from the crystal. We
have full evidence that it is only special kinds of molecular
change that exhibit the special signs called sentient; we have as
good evidence that only special aggregations of molecules are
vital, and that sensibility never appears except in a living
organism, disappearing with the vital activities, as we know that
banks and trades-unions are specifically human institutions.”
The considerations which are here applied to vital activity, may
be paralleled by others applied to intelligence. They will show us
that however profoundly rational may be that world which is
commonly spoken of as irrational, yet that its rationality is not
truly the attribute of the various animals which perform such
admirably calculated actions, but truly belongs to what is the
ultimate and common cause of them all, and to that only.
There is, indeed, a logic in mere “feeling,” there is a logic even
in insentient nature; but that logic is not the logic of the crystal
nor of the brute; its true position must be sought elsewhere. It
is in them, but it is not of them.
However, let us patiently consider a little this hypothesis of an
innate, unconscious intelligence as the cause of the various
strictly, or analogically, instinctive actions of animals.
It is in the first place plain that no intelligence could exist so as
to adjust “means” to “ends,” except by the aid of memory; and
“memory” has therefore been freely attributed even to the lower
animals. Let us see, then, what the term “memory” really
denotes. Now we cannot be said to remember anything unless
we are conscious that what is again made present to our mind
has been present to our mind before. An image might recur to
our imagination a hundred times, but if at each recurrence it
was for us something altogether new and unconnected with the
past, we could not be said to remember it. It would rather be an
example of extreme “forgetfulness” than of “memory.” In
“memory,” then, there are and must be two distinct elements.
The first is the reproduction before the mind of what has been
before the mind previously, and the second element is the
recognition of what is so reproduced as being connected with
the past.
There is yet a further distinction which may be drawn between
acts of true recollection.
We are all aware that every now and then we direct our
attention to try and recall something which we know we have
for the moment forgotten, and which we instantly recognise
when we have recalled it. But besides this voluntary memory we
are sometimes startled by the flashing into consciousness of
something we had forgotten, and which we were so far from
trying to recollect that we were thinking of something entirely
different.
There are, then, two kinds of true memory—one in which the
will intervenes, and which may be spoken of as recollection, and
the other in which it does not, and which may be termed
reminiscence. Neither of these can exist in a creature destitute
of true self-consciousness. There are, however, two other kinds
of repeated action which take place even in ourselves, and
which should be carefully distinguished.
The first of these are practically automatic actions, which are
repeated unconsciously after having been learned, as in
walking, reading, speaking, and often in playing some musical
instrument. In a certain vague and improper sense we may be
said—having learned how to do these things—to recollect how
to do them; but unless the mind recognises the past in the
present while performing them they are not instances of
memory, but merely a form of habit in which consciousness may
or may not intervene.
The second class of repeated actions just referred to are, on the
other hand, those in which consciousness cannot be made to
intervene, and are mere acts of organic habit. Thus a man
wrecked on an island inhabited by savages, and long dwelling
there, may at first have the due action of his digestive organs
impeded by the unwonted food on which he may have to live.
After a little while, however, the evil diminishes, and in time his
organism may have “learnt” how to correspond perfectly with
the new conditions. Then with each fresh meal the alimentary
canal and glands must practically “recognise” a return of the
recently obtained experience, and repeat its freshly acquired
power of healthy response thereto. Can “memory” be properly
predicated of such actions of the alimentary glands? It can be
so predicated only by a perversion of language. It is not
memory, because not only is it divorced from consciousness as
it occurs, but it cannot anyhow be made present to
consciousness. Again, a boy at school has had a kick at football,
which has left a deep scar on his leg. That boy, now become an
old man, still bears the same scar, though all his tissues have
been again and again transformed in the course of seventy
years. Can the constant reproduction of the mark, in any
reasonable sense, be said to be an act of, or due to, memory?
Evidently it cannot, and neither can it be reasonably predicated
of any of the actions of plants or of the lowest animals.
As, then, “memory” cannot be predicated, except by an abuse
of language, of the lower forms of life, it would appear that
neither intelligence nor rationality can truly exist in them, so as
to preside over all those actions of nutrition, repair,
reproduction, and instinct which we have examined and
distinguished.
Nevertheless, Hartmann and his followers do not on this
account hesitate to ascribe true intelligence to unconscious
nature, and though such ascription may seem too absurd to
deserve serious consideration, it would nevertheless be a great
mistake to despise such opinions. For, as Mr. Lewes truly says,34
“As there are many truths which cease to be appreciated
because they are never disputed,” so there are many errors
which are best exposed by allowing them to run to a head. Mr.
Butler, who carries this hypothesis of unconscious intelligence to
its last consequences, asks,35 “What is to know how to do a
thing?” His answer is, “Surely, to do it.” And he represents how,
when many things have been perfectly learnt, they may be
performed unconsciously. In a very amusing chapter on
“Conscious and unconscious knowers,” he says, “Whenever we
find people knowing they know this or that ... they do not yet
know it perfectly.” In another place he says,36 “We say of the
chicken that it knows how to run about as soon as it is hatched
... but had it no knowledge before it was hatched? It grew eyes,
feathers, and bones; yet we say it knew nothing about all this....
What, then, does it know? Whatever it knows so well as to be
unconscious of knowing it. Knowledge dwells on the confines of
uncertainty. When we are very certain we do not know that we
know. When we will very strongly, we do not know that we will.”
Now the fact is that there is great ambiguity in the use of the
word know. Just as before with the term memory, so also here,
certain distinctions must be drawn if we would think coherently.
A. To “know,” in the highest sense which we give to the word, is
to be aware (by a reflex act) that we really have a certain given
perception. It is a voluntary, intelligent, self-conscious act,
parallel to that kind of memory which we before distinguished
as “recollection.”
B. We also say we “know” when we do not use a reflex act, but
yet have a true perception—a perception accompanied by
consciousness—as when we teach, and in most of our ordinary
intellectual acts.
C. When we so “know” a thing that it can be done with perfect
unconsciousness, we cannot be said to “know” it intellectually,
although in doing that thing our nervous and motor mechanism
acts (in response to sensational stimuli) as perfectly as, or more
perfectly than, in our conscious activity. The “knowledge” which
accompanies such “unconscious action” is improperly so called,
except in so far as we may be able to direct our minds to its
perception, and so render it worthy of the name—as we have
seen we may direct attention to our unconscious reminiscences,
and so make them conscious ones. In the same way then in
which we have already distinguished such acts of memory
(while unconscious) as sensuous memory, so we may
distinguish such acts of apprehension (while unconscious) as
sensuous cognition. By it we can understand, to a certain
extent, what may be the “knowledge” or “sensuous cognition”
of mere animals.
D. Besides the above three kinds of apprehensions, we may
distinguish others which can be only very remotely, if at all,
compared with knowledge, since they can never, by any effort,
be brought within the sphere of consciousness. Such are the
actions of our organism by which it responds to impressions in
an orderly and appropriate but unfelt manner—the intimate
actions of our visceral organs, which can be modified, within
limits, according to the influence brought to bear on them, as
we may see in the oarsman’s hand, the blacksmith’s arm, and
the ballet-dancer’s leg.
If such actions could be spoken of as in any sense
apprehensive, they would have to be spoken of as “organic
cognitions,” but they may be best distinguished as “organic
response” or “organic correspondence.”
That the inorganic world, no less than the organic, is instinct
with reason, and that we find in it objective conditions which
correspond with our subjective conceptions, is perfectly true;
but when once the profound difference between mere organic
habit and intellectual memory is apprehended, there will be little
difficulty in recognising the yet greater difference between
“organic correspondence” and the faithfulness of inorganic
matter to the laws of its being.
That the absence of consciousness in actions which are
perfectly performed, does not make such actions into acts of
“perfect knowledge,” is demonstrated by every calculating
machine. No sane person can say that such a machine
“possesses” knowledge, though it is true that it “exhibits” it.
Similarly we must refuse to apply the terms “memory” and
“intelligence” to the merely organic activity of animals and
plants.
The assertion that in the vegetal and lowest animal forms of life
there is an innate but unconscious intelligence, is an assertion
which contains an inherent contradiction, and is therefore
fundamentally irrational. Anyone who says that blind actions (in
which no end is perceived or intended) are truly intelligent ones,
abuses language. The meaning of words is due to convention,
and anyone who calls such actions truly intelligent, divides
himself from the rest of mankind by refusing to speak their
language.
What experience have we which can justify such a conception
as that of “unconscious intelligence?” We are indeed aware of a
multitude of actions which are evidently the outcome of
intelligence, but which (like the analogous action of a calculating
machine) are performed by creatures really unconscious, though
they may possess consentience. But consciousness is the
accompaniment of all those actions which we know to be
intellectual and rational. Our experience then contradicts the
hypothesis of the existence of any such thing as “unconscious
intelligence.” Such a thing is indeed no true concept, for it is
incapable not only of being imagined but also of being really
conceived of. It resembles such unmeaning expressions as “a
square pentagon” or a “pitch-dark luminosity.”
Nevertheless, our experience is in favor of the existence of an
intelligence which can implant in and elicit from unconscious
bodies activities which are intelligent in appearance and result.
Thus we can construct calculating machines and train animals to
perform many actions which have a delusive semblance of
rationality.
“Truly intelligent action” we know as being intelligent and
rational in its foresight, and therefore as necessarily conscious in
the very principle of its being.
“Unconsciously intelligent action,” improperly called “intelligent”
or “wise,” is that which is intelligent and wise only as to its
results, and not in the innermost principle of the creatures
(whether living or mere machines) which perform such action.
To speak technically, we have “formal” and “material”
intelligence, as we have “formal” and “material” vice and
virtue.37 We have already distinguished between the “formal”
and the merely “material” discoverer of a new fossil, and this
distinction is one which it is most important to bear in mind. It
is the failure to apprehend this distinction which is the root of a
vast number of modern philosophical errors, and the error which
consists in asserting the reality of “unconscious intelligence” is
one of them.
In fact “intelligence” exists very truly, in a certain sense, in the
admirably directed actions blindly performed by living beings. It
is not, however, “formally” in them, but exists formally in their
ultimate cause. Nevertheless that intelligence is so implanted
within them that it truly exists in them “materially” though it is
not “formally” in them.
We have here, then, the answer to the question, “What is the
rationality of the irrational?” It is a rationality which is very
really, though not materially, present in the irrational world,
while it is formally present in that world’s cause and origin.
To every Theist this answer will be a satisfactory one. To him
who is not a Theist there is no really satisfactory answer
possible. This is a question not of theology but of pure reason
antecedent to all theology. To reason, and to reason only, I
appeal when I affirm that the existence of a constant,
pervading, sustaining, directing, and all-controlling but
unfathomable Intelligence which is not the intelligence of
irrational creatures themselves, is the supreme truth which
nature eloquently proclaims to him who with unprejudiced
reason and loving sympathy will carefully consider her ways. He
can hardly fail to discover, immanent in the material universe,
“an action the results of which harmonize with man’s reason; an
action which is orderly, and disaccords with blind chance, or ‘a
fortuitous concurrence of atoms,’ but which ever eludes his
grasp, and which acts in modes different from those by which
we should attempt to accomplish similar ends.”38 For myself, I
am bound humbly to confess that the more I study nature the
more I am convinced that in the action of this all-pervading but
inscrutable and unimaginable intelligence, of which self-
conscious human rationality is the utterly inadequate image,
though the image attainable by us, is to be sought the sole
possible explanation of the mysterious but undeniable presence
in nature of a rationality in that which is in itself irrational.—
