_DAVID HUME AS A METAPHYSICIAN._
But the mischief lieth here; that when men of less leisure see them
who are supposed to have spent their whole time in the pursuit of
knowledge professing an entire ignorance of all things, or
advancing such notions as are repugnant to plain and commonly
received principles, they will be tempted to entertain suspicions
concerning the most important truths which they had hitherto held
sacred and unquestionable.--Berkeley's _Hylas and Philonous_.
In no department of science is it possible for an enquirer to advance
considerably beyond all his predecessors without serving as a light by
whose aid his successors may advance somewhat beyond him. This is the
only apology that I feel disposed to offer for the freedom with which I
am about to criticize one who, having been, by judges so competent as
Adam Smith and Professor Huxley, pronounced to be 'by far the greatest
philosopher' and 'acutest thinker' of his own age, would, doubtless, be
at least on a level with the greatest philosophers of the present age if
he were living now. The veriest cripple that can manage to sit on
horseback may contrive to crawl some few steps beyond the utmost point
to which his steed has borne him, and, if those steps be uphill, may, by
looking back on the course he has come, perceive where the animal has
deviated from the right road. Yet he does not on that account suppose
that his own locomotive power is in any respect to be compared to his
horse's; neither need an annotator on Hume, when pointing to holes in
his author's metaphysical coat, be supposed not to be perfectly aware
that it is the strength, not of his own eyes, but of the spectacles
furnished to him by his author, that enables him to perceive them.
The concentrated essence of Hume's metaphysics is to be found in 'An
Enquiry concerning Human Understanding,' forming part of a volume of
Essays which Hume published somewhat late in life, and which he desired
might 'alone be regarded as containing his philosophical sentiments and
principles.' To a formal, though necessarily rapid, examination of the
results of this 'Enquiry,' the present chapter will be almost
exclusively devoted. Often as the operation has been performed already,
there are two reasons why its repetition here may not be without
utility: for, first, its subject is a treatise containing the germs of
much subsequent and still current speculation which, in so far as it is
merely a development of those germs, cannot but be infected by whatever
unsoundness may be inherent in them; and, secondly, because the subject,
hackneyed as it may seem, is so far from being exhausted, that there is
scarcely one among the doctrines embodied in it to which, as I proceed
at once to show, fresh objection, more or less grave, may not be taken
by a fresh investigator.
To begin very near indeed to the beginning, let us take, first, the
section of the 'Enquiry' which treats of the 'Origin of Ideas.' All the
perceptions of the mind may, according to Hume, be divided into two
classes, whereof the one consists of all those 'more lively
perceptions,' termed by him indifferently Impressions or Sensations,
which we experience when we 'hear, or see, or feel, or love, or hate, or
desire, or will:' the other, of those 'less lively perceptions of which
we are conscious when we reflect on any of the sensations
above-mentioned,' and which are commonly denominated thoughts or ideas.
'All our ideas or more feeble perceptions,' he continues, 'are copies of
our impressions or more lively ones,' the 'entire creative power of the
mind amounting to no more than the faculty of compounding, transposing,
augmenting, or diminishing the materials afforded by the senses and
experience.' So confident is he of the literal accuracy of this
statement, as to proceed to intimate that whenever we find in
conversation or argument 'a philosophical term employed seemingly
without any idea or meaning,' we have only to enquire from what
impression its idea, if it have one, is derived, when, if no impression
can be adduced, we may be sure that no idea is present either. The only
phenomenon opposed to this rule, which he professes himself able to
think of, is that of a person who, of a colour--as, for instance,
blue--with which he is familiar, is able to conceive a shade somewhat
different from any of the shades which he has actually seen; but this
instance he disregards as too singular to affect the general maxim, to
which, as he might have added, it is not really an exception, any more
than would be the power of a person who had never seen a mountain higher
than Snowdon or Mont Blanc to conceive one as high as Chimborazo or
Mount Everest, for, equally in both cases, the ideas are copies of
sensible impressions, although of complex, not simple, ones--of colour
and graduation in the first case, of size and increase in the second.
Still, there is at least one genuine exception, which it is the more
remarkable that Hume should have overlooked, as it may be said to have
stared him in the face from the very subject-matter he was considering.
Our idea of idea itself, from what sensible impression is that derived?
We have just been told that the difference between an idea and a
sensation is that the first is a copy of the second, a feeble copy of a
lively original. The idea therefore is not itself a sensation; the copy
is not itself an original. Neither consequently can the idea or notion
which the mind proceeds to form of any of its previous ideas be derived
from or be a copy of a sensation: it cannot have entered the mind 'in
the only manner by which,' according to Hume, 'an idea can have access
to the mind, to wit, by actual feeling and sensation.'
Let me not be misunderstood. Let me not be supposed to be courting
collision with the Berkleian thesis of the non-existence of abstract
ideas. I do not for one moment doubt that all our general or class
notions of sensible objects or events are merely concrete ideas of
individual objects or events--that, for instance, whenever we talk of
man or motion in general, we are really thinking of some particular man
or motion, which, as possessing all properties common to all men or
motions, serves as a representative of the entire _genus_. Neither am I
prepared to deny, although scarcely either prepared to admit, that even
of abstract qualities all our general or class notions are equally ideas
of particular specimens of those qualities; that, when we speak, for
instance, of virtue or vice in general, we are thinking of some
particular exhibition of some particular kind of virtue or vice. Nay, I
am not even concerned to deny that our idea of idea in general may
possibly be a copy of some particular one of our previous ideas which,
for the nonce, serves to represent all our other previous ideas. I limit
myself to saying that our idea of idea in general, whether it be or be
not itself an abstraction, is, at all events, not a copy of sensation. I
admit that it thereby differs essentially from most, if not all, other
general ideas. Possibly it may be only through my having myself felt
the promptings of some particular virtue or vice, that I am able to form
an idea of that particular virtue or vice. If so, I admit that my idea
of that particular virtue or vice is but, as Hume would say, a copy of
my feeling. And since, undoubtedly, I can feel myself thinking, or
perceiving, or performing any other mental operation, I am bound to
admit, further, that my idea of any such operation may equally be
described as a copy of a sensation which I have experienced. All I
contend for is that if, after having formed my idea, either of a mental
operation or of anything else whatever, I proceed to ask myself what
sort of an entity that idea is, the answer which I give myself, or, in
other words, the idea which I form of my previous idea, being a copy of
idea, cannot be a copy of sensation.
So much must surely be conceded to me, for that white, being white,
cannot be also black is not nearly so certain as that idea and
sensation, being two distinct things, idea of idea cannot be idea of
sensation. The concession, indeed, is likely enough to be accompanied by
an exclamation of wonder that so microscopic a flaw in an elaborate
exposition should be thought worth pointing out; but Hume himself would
certainly not have so retorted. Of the doctrine which I am impugning,
viz., that every _idea_ is copied from some preceding _sensation_, he
had spoken as follows:--'Those who would assert that this position is
not universally true, nor without exception, have only one, and that an
easy, method of refuting it, by producing the idea which, in their
opinion, is not derived from this source. It will then be incumbent on
us, if we would maintain our doctrine, to produce the impression or
lively perception which corresponds to it.' He was much too candid not
to have acknowledged that this challenge of his had been fairly and
fully met. He was not a man to refuse to own himself refuted when, after
distinctly intimating that the production of one single idea, having no
perception correspondent to it amongst those which we experience 'when
we see, or hear, or feel, or love, or hate, or will, or desire,' would
suffice for his entire refutation, he found such an idea produced. He
knew too well also to what enormous errors of thought minute errors of
expression may lead, to disregard any speck of inaccuracy in any one of
his definitions. The apparently slight oversight committed by him on
this occasion will, indeed, be presently seen to have sensibly
contributed to lead him subsequently into a mistake of no small
practical moment.
We come next to the 'Association of Ideas,' the influence of which
almost all of Hume's successors, as well as himself, seem to me to have
greatly over-rated. That there is a 'principle of connection between the
different thoughts or ideas of the mind' is, as he says, sufficiently
evident; and that this principle is, as he was apparently the first to
remark, threefold, deriving its efficacy from resemblance, contiguity in
time or place, and cause or effect, may also be admitted with little
qualification. But I presume to think that he is quite incorrect in
adding that, in virtue of the aforesaid principle, ideas 'introduce each
other with a certain degree of method or regularity.' You are walking,
let us suppose, through Hyde Park, thinking of nothing more particular
than that the morning is a pleasant one, when you suddenly find yourself
in imagination pacing the shore of the Dead Sea, and, pausing to ask
yourself how you got there, you discover, perhaps, that it was by the
following steps. Remarking some landscape effect in the distance, you
were reminded of a similar one which you had remarked years before while
taking a walk fifty miles off in Sussex. Here resemblance operated. Then
you recollected how during that walk you were thinking about Mr. Buckle,
whose lucubrations you had been conning over before starting. Here
entered contiguity both of time and space. The name of Buckle reminded
you how that promising writer ended his travels abroad by dying of a
fever which he caught while sailing over the sites of the engulphed
cities of the plain. Here cause and effect came into action; and, so
far, everything accords with Hume's theory. But if you repeat the same
walk to-morrow, the same landscape effect will almost certainly suggest
a train of ideas quite different from that of to-day. Perhaps it may
begin by reminding you of landscape effects in general; then of Mr.
Ruskin, who has discoursed so eloquently on that topic, and next of Mr.
Ruskin's 'Stones of Venice,' from whence it is equal chances whether
your thoughts radiate, on one side of the compass, to stone china, or
Stoney Stratford, or Stonewall Jackson, or, on the other, to the
'Venetian Bracelet,' L. E. L. and Fernando Po, or to that effective
adaptation of the Venetian style of architecture, the Railway Station at
St. Pancras, and thence to some town or other on the Midland Line.
These examples will be readily recognized as fair average specimens of
those unpremeditated trains of thought with which we are all familiar.
Is there, then, in the arrangement of the consecutive thoughts of which
the several trains are composed, any method or regularity common, I will
not say to all, but to any two of them? According to Hume and to most of
his successors in the same path of enquiry, there ought to be. Thus the
illustrious author of the 'Analysis of the Human Mind' affirms, without
rebuke or protest from any one of his not less illustrious commentators,
that 'our ideas spring up or exist in the order in which the sensations
existed of which they are the copies: that of those sensations which
occurred synchronically, the ideas also spring up synchronically, and
that of the sensations which occurred successively, the ideas rise
successively.' And he adds, 'this is the general law of the Association
of Ideas,' remarking, by way of illustration, that, as 'I have seen the
sun, and the sky in which it is placed, synchronically, if I think of
the one I think of the other at the same time'; and that, as when
committing to memory a passage of words, as, for instance, the Lord's
Prayer, we pronounce the words in successive order, and have
consequently the sensation of the words in successive order, so when we
proceed to repeat the passage, 'the ideas of the words also rise in
succession, _Our_ suggesting _Father, Father_ suggesting _which, which_
suggesting _art_, and so on to the end.'[29]
Oh Law! Law! most abused of scientific terms, what an infinity of
dogmatic illegalities are committed in thy name! The one thing which
scientific law implies is regularity of occurrence, but what regulation
is it that is obeyed in common by a number of sequences commencing at
the same point in Hyde Park, yet terminating, one in Africa, another in
America, a third in Palestine, and a fourth in the centre of England?
Can it have been seriously said that it is impossible for us to think of
the sky without thinking simultaneously of the sun which illuminates
the sky? Is it impossible for us to think instead of the ether which
constitutes it, or peradventure even of the resemblance between its
celestial azure and what Moore calls the 'most unholy blue' of some
frolicsome Cynthia's eyes? And is it not notorious that when saying the
Lord's Prayer--a prayer which, in spite of the injunction by which its
original dictation was accompanied, to 'avoid vain repetitions, as the
heathen do,' many Anglican clergymen insist on repeating half-a-dozen
times in a single service--is it not notorious that, so far from the
idea of one word suggesting to us the idea of the next, no small effort
of attention is requisite to enable us to have any idea at all of what
we are saying?
It would seem that the author of the 'Analysis' either could not help
asking himself questions like these, or, without asking the questions,
could not help seeing the commonplace truths involved in the inevitable
replies to them. It would seem to have been semi-consciousness of the
utter inability of the evidence first cited by him to justify belief in
the necessarily simultaneous or successive occurrence of the ideas of
simultaneously or successively experienced sensations, which made him
have recourse for help to _complex_ ideas. 'If,' he says, 'from a stone
I have had synchronically the sensation of colour, the sensation of
hardness, the sensations of shape and size, the sensation of
weight,--when the idea of one of these sensations occurs, the ideas of
all of them occur.' Because, then, I may have ascertained by experience
that a stone is white, hard, and round, two feet in diameter, and twenty
pounds in weight, am I really incapable, if I happen to break my shin
against it, of thinking how hard it is, without thinking also how heavy;
or, when trying to lift it, of thinking how heavy it is without
thinking likewise of its shape and colour? Elsewhere the same writer
speaks of 'ideas which have been so often conjoined that whenever one
exists in the mind, the others immediately exist along with it, seem to
run into one another, to coalesce, as it were, and out of many to form
one idea.' But which are the ideas whereof this can be said? The writer
instances those simple ideas, colour, hardness, extension, weight,
which, he says, make up our complex ideas of gold or iron. He instances,
too, the ideas of resistance, muscular contractility, direction,
extension, place, and motion, of which he says our apparently simple
idea, weight, is compounded. Does he mean, then, that we cannot
entertain the idea of yellowness without entertaining at the same time
all the other ideas necessary for composing the idea of gold, and
entertaining, too, that idea in addition to all the rest? Does he mean
that a train of thought cannot commence with place without terminating
with weight? Of course he means nothing of the kind, although so he
distinctly says. Rather, he appears to mean the direct converse, viz.,
that we cannot have the idea of gold or of weight present to the mind,
without having present also all the simple ideas of which those complex
ideas are compounded--in other words, not that the occurrence of any one
component necessarily calls up all the other components, and forms with
them the compound, but that the appearance of the compound brings with
it all its separate components.
But neither does this seem to be a strictly correct representation. I am
not sure that I can think of gold without thinking of yellowness, but I
am positive that I can without thinking of hardness. Nor is there any
doubt that the youngest child knows perfectly well what it means when,
trying to lift a stone, it calls the stone heavy, although it might not
be more difficult to make the stone itself than the child understand
what is meant by muscular contractility. I own that if it be here
demanded of me how a compound can be present unless every one of its
components be present also, I may under pressure be constrained to
suggest that possibly, after all, the very term _compound_ or _complex
idea_ may be somewhat of a misnomer, or at any rate that the
constituents of such an idea are much fewer than is commonly supposed.
Be it admitted that the idea, so styled, could not have been formed
without the instrumentality of other and previously-formed ideas, still
it does not follow that the instruments of production should for ever
after accompany the product. The rackful of dry toast which is brought
to you for breakfast could scarcely have been so neatly sliced without
the help of a knife, but the toast is not the less in bodily presence on
the breakfast-table because the knife that cut it has been left behind
in the kitchen. Neither, although you may probably be aware that salt,
suet, sugar, and spice enter into the composition of a Christmas
pudding, do you necessarily think of those separate ingredients when you
think of the pudding, any more than you would see them separately if you
saw the pudding. The only qualities which you apparently cannot help
thinking of when you think of the pudding are its size, shape, and
colour.
One word more about the assumed regularity in the succession of ideas.
That when you are repeating a familiar form of words or playing a
familiar piece of music, every word uttered or note struck, by reason of
connexion of some sort between itself and the word or note next in
order, enables you without the smallest mental effort to utter that
word or strike that note, is too notorious to be questioned. But I do
very earnestly question whether the connexion that thus operates is an
association of ideas. How can it be, when, as frequently happens, you
have not the smallest idea of what it is you are saying or playing? Have
you not often, after reverently saying grace, like the decent
paterfamilias you probably are, occasioned a giggle round the table by
saying it again a minute or two afterwards, in utter unconsciousness
that you had said it just before? Or, if I may so far flatter myself as
to fancy my reader a fair daughter of the house instead of the staid
house father--has it never happened to you, Miss, while executing a
brilliant performance on the piano, to have been so entirely engrossed
by an animated flirtation carried on simultaneously, that, if at the
conclusion of the piece you had been asked what you had been playing,
you could not have replied whether it was _La ci darem la mano_ or _Non
mi voglio maritar_? And is it not evident that non-existent ideas cannot
have called real ideas into existence?
My own modest contribution towards explanation of these mysterious
phenomena is as follows. Apart from association of _ideas_, there is a
separate and independent association--to wit, association of
_volitions_. While committing to memory a form of words, or trying a new
piece of music, every separate movement of your tongue or of your
fingers is consequent on some separate volition. Each series of
movements is consequent on a series of volitions. By being repeatedly
made to follow each other in the same order, the several volitions
become connected with each other, so that whenever the mind desires to
marshal them in the aforesaid order, each one, as it presents itself,
brings with it the next in succession, until the whole series is
completed; while, as each volition has consequent upon it a
corresponding movement, a series of corresponding movements
simultaneously takes place. The mind meanwhile is quite unconscious of
the muscular movements that are going on. What it is conscious of are
the volitions without which no voluntary movements of the muscles could
have been made, and of which the mind must needs be conscious, because a
volition of which the mind was not conscious would be an involuntary
volition, a birth too monstrous for even metaphysics to be equal to. But
although necessarily conscious of these volitions, the mind is only
momentarily conscious. It pays them barely an instant's attention, and
therefore instantaneously forgets them, retaining no more trace of them
than if they had never been.
The doctrine of Hume's which next confronts us is his famous one
concerning Cause and Effect. He commences it by explaining that all
objects of human enquiry are divisible into two kinds--1. Relations of
Ideas, like those of which geometry, algebra, and arithmetic treat, and
which are either intuitively certain, or 'discoverable by the mere
operation of thought, without dependence on what is anywhere existent in
the universe,' as, for example, the truths demonstrated by Euclid, which
would be equally incontestable even 'though there were never a circle or
a triangle in nature:' 2. Matters of Fact, as, for example, the sun's
rising and setting, or the emission of light and heat by fire, which are
never discoverable by unassisted reason, because of no one of them would
the opposite imply a contradiction or be consequently inconceivable; and
in our knowledge of any one of which we can never 'go beyond the
evidence of our memory and senses,' except by means of reasons derived
from experience of some fact or facts connected in some way or other
with the particular matter of fact we are considering.
So far, all is comparatively plain sailing, but Hume now propounds a
difficulty which he at first presents as seemingly insurmountable, but
which I cannot help thinking to be mainly of his own creation, and which
he himself, almost immediately afterwards, suggests a mode, though a
very inadequate mode, of overcoming. His language here is not marked by
his usual perspicuity, or rather--to speak without respect of
persons--it contradicts itself in most astounding fashion; but his
meaning is not the less certainly the following, for there is no other
construction which his words will bear.
'What,' he asks, 'is the foundation of all conclusions from experience?'
Why is it that, having found that such an object has always been
attended with such an effect, we infer that similar objects will always
be attended with similar effects? The proposition that a certain
antecedent has always been followed by a certain consequent, and the
proposition that the same antecedent will be followed by the same
consequent, are not identical. What, then, is the connexion between them
which causes one to be inferred from the other? The connexion is
unhesitatingly pronounced by him to be neither intuitively perceived,
nor yet to be 'founded on any process of the understanding.' If you
insist that the inference is made by a chain of reasoning, he challenges
you to produce that reasoning, and taking for granted that you have none
to produce, he proceeds to indicate what principle it is which, in his
opinion, does determine us to form the inference. That principle he
declares to be custom or habit, by which alone, he asserts, we are,
after the constant conjunction of two objects, determined to expect the
one from the appearance of the other; adding that all inferences from
experience are effects of custom, not of reasoning.
What is the correct answer to this question of Hume's I shall be rash
enough to endeavour to indicate a little further on; meanwhile there can
be no temerity in saying that whatever be the right answer, Hume's is
certainly a wrong one. Habit plainly cannot be its own parent. It
enables us to repeat more easily what we have already repeatedly done,
but it cannot be the cause of our doing or being able to do anything for
the first time. An infant that has once burnt its fingers by touching
the flame of a candle, expects that if it touch the flame again it will
burn its fingers again, but it does not expect this because it has been
in the habit of expecting it. Neither, if we be here bidden to
understand that the habit referred to is not any mental habit of our
own, but a habit which we have observed certain phenomena to have of
following each other, shall we thereby be brought one whit nearer the
truth. Our infant with the burnt finger has not observed that flame is
in the habit of burning. It only knows that flame did burn on the one
occasion on which it tried the experiment, which experiment it
consequently declines to repeat. Besides, no one needs to be told that
inferences, though thus capable of being drawn from single occurrences,
are drawn with increased confidence from observation of habit. We all
know already that, having always found that fire burns, we infer that it
always will burn. What we want to know is, why we draw this inference.
This is the question which Hume puts, and respecting which he gives
very positively the negative reply that the inference is not drawn
either intuitively, nor yet by any process of the understanding. Yet
that a body when not moving must needs be at rest, is not more certainly
demonstrable than that inferences cannot possibly be drawn except in one
or other of these two ways. Is not every inference a species of belief,
and must not every belief be either innate within us, or have been
acquired artificially; and, as in the latter case, it is a mental
acquisition, must it not in that case have been acquired by an operation
of the mind or understanding? Is it not clear, then, that inferences
must always be either intuitive or ratiocinative; and is it not strange
that Hume should deny that they ever are so? Yet stranger still is it,
that even while denying them to be either one or the other, he, almost
in the same breath, pronounces them to be both. For, after having on one
page denied that they are founded on reason, or any process of the
understanding, he describes them on the next page as being not simply
founded on, but as being themselves 'processes of the mind,' 'processes
of thought,' and immediately afterwards 'arguments,' nay, '_reasonings_
from experience;' and, yet again, after as short a pause, these very
same 'reasonings,' and 'arguments,' and 'processes of the mind and
thought,' he concludes by styling 'natural instincts which no reason or
process of the thought or understanding is able either to produce or to
prevent'--'operations of the soul as unavoidable' when the mind is
placed in certain circumstances, as it is 'to feel the passion of love
when we receive benefits, or hatred when we meet with injuries.'
What are we to say to a description of mental operations which are and
are not 'arguments' and 'reasonings,' which are and are not 'processes
of thought,' which are not 'intuitive,' and which yet are 'instincts?'
How are we to account for such amazing inconsistencies in an exposition
of one of the greatest of philosophers? With all humility, I submit the
following as a possible solution of the enigma.
The one solitary ground on which Hume denies the argumentative and
ratiocinative character of what he nevertheless terms arguments and
reasonings, is the impossibility of producing the _chains_ of argument
or reasoning of which they are composed. But this impossibility can at
most only prove that the reasonings are elementary, and have,
consequently, no component parts into which they can be resolved. But
reasoning is not the less reasoning for being elementary, or for being
only a single link in a chain, instead of being itself a chain composed
of many links. Still, being elementary, it may occur to, and pass
through, the mind with extreme rapidity--with not less rapidity than an
intuition or instinct, for which therefore it may easily be mistaken, as
accordingly it has actually been by Hume. But that a reasoning from
experience is not really an instinct is certain, firstly, because
intuitive or instinctive reasoning, if not a phrase absolutely devoid of
meaning, is a contradiction in terms; and, secondly, because, if it were
instinctive, it would precede instead of following experience, and a
baby, instead of finding out that flame burns by touching it, would know
beforehand that flame burns, and would therefore not touch it.
From the species of Belief constituted by an inference from experience,
Hume, by an easy transition, passes on to Belief in general, which he
defines to be 'nothing but a more vivid, lively, forcible, firm, steady
conception of an object, than what the imagination alone is ever able
to attain,' referring, by way of illustration, to an animal with the
head of a man and the body of a horse, which anyone can imagine, but no
one can believe in, and desiring us apparently to suppose that if our
groom were to come and tell us that he had found a centaur feeding in
the paddock beside our favourite saddle-horse, our sole reason for
believing in the horse and for not believing in the centaur would be our
greater ability to conceive the one than the other. That such a
definition should for a moment have satisfied its author's curiosity, is
itself a psychological curiosity which must not, however, be suffered to
detain us. Whoever, not content with knowing perfectly well what belief
is, desires to have his knowledge of it set down in writing, should read
the admirable notes on the subject, with which Mr. John Mill and Mr.
Bain have enriched the last edition of Mr. James Mill's 'Analysis of the
Human Mind.' Most readers, however, will probably be disposed to avail
themselves here of a rather favourite phrase of Hume himself, and to
plead that, 'if we agree about the thing, it is needless to dispute
about terms;' and it is not unlikely that such of them as may have
formed their notion of metaphysical discussions in general from the
specimens given above, may go so far as to hint a doubt whether any of
the nice verbal distinctions which metaphysicians so much affect, are
really worth the trouble required to understand them. Nor would anyone,
perhaps, be much the worse for acting upon this suspicion, provided
that, in accordance with it, he kept altogether aloof from the studies
which it disparages. His ideas need not be the less clear because he
neither knows nor cares of what they are copies, nor whether they are
copies of anything; nor will the order of their occurrence be at all
affected in consequence of his being similarly careless, whether that
order is or is not governed by a _law_ of association; neither need his
inferences from experience be the less sound in consequence of his never
having enquired how or why they are deduced. But although the most
absolute ignorance and corresponding indifference about these and
kindred topics may not tend in the least to disqualify him for
performance of the whole duty of man, it is not the less important that,
if he do care to know aught about them, his knowledge should be exact,
for there is no knowing beforehand how luxuriantly the minutest germ of
theoretical error may ramify in practice, or into what substantive
quagmire trust in deceitful shadows may lead. These respectable
aphorisms may be beneficially borne in mind during perusal of what is
about to be said.
If the fact were really, as Hume supposed, that we have _no_ reason for
our inferences from experience, and draw them only because either we
have been in the habit of drawing them, or because we are so constituted
as to be unable to help drawing them, the reason of our drawing them
plainly could not be that we perceive any necessary connection between
antecedent and consequent events, or any force or power binding these
together as cause and effect. Accordingly, Hume does not scruple to
affirm that 'we have no idea of connection or power at all, and that
these words are absolutely without meaning when employed either in
philosophical reasoning or in common life.' Every idea, he argues,
referring to a rule which he somewhat hastily supposes himself to have
already proved to be without exception, must needs have been copied from
some preceding sensible impression, but neither from within nor from
without can we have received an impression from which this particular
idea can have been copied. No keenest scrutiny of any portion of matter,
no study of its external configuration or internal structure could,
previously to experience, enable us to conjecture that it could produce
any effect whatever, still less any particular effect: could enable us
to guess, for instance, that flame would burn, or ice would chill, if
touched. Nor even though on once touching flame we get our fingers
burnt, are mature philosophers like us to conclude, as if we had no more
intelligence than so many babies, that if we touch again we shall be
burnt again. All we have as yet learnt from the experiment is that the
sensation of touching fire has once been followed by the sensation of
burning, but nothing has occurred to suggest that in the first sensation
lurked any secret power of producing the second. And what a single
experiment does not prove, no number of repetitions of precisely the
same experiment with precisely the same results can prove. Even though
on a lengthened course of experience we have found that in every case of
our touching flame our fingers have been burnt, we are still as far as
ever from perceiving any bond of connection between the two events. We
do indeed believe that as flame when touched has hitherto invariably
burnt, so, whenever touched hereafter, it will hereafter invariably
burn; but this, according to Hume, we believe simply because by long
practice we have contracted such a habit of associating the idea of
touched flame with burnt fingers, that whenever we witness the one we
cannot help expecting the other.
Neither, if, withdrawing our eyes from the outward world, we cast them
inwardly upon the operations of our own minds, shall we, according to
Hume, any the more discover what we are in search of. What though we
know by experience that whatever, within certain limits, our will
appoints, our bodily organs or mental faculties will ordinarily perform;
that our limbs will move as we wish them, and our memory, reason, or
imagination bring forward ideas which we desire to contemplate, what
knowledge have we here beyond that of certain volitions and certain
other acts taking place in succession? What smallest evidence have we of
any connection between the volitions and the other acts? A volition is
an operation of the mind, is it not? and body is matter, is it not? And
do you pretend to know--can you form the smallest approach to a
guess--how mind is united with body, and how it is possible therefore
for the refined spiritual essence to actuate the gross material
substance. If you 'were empowered by a secret wish to remove mountains
or to control the planets in their orbit,' would such extensive
authority be one whit more inexplicable than the supposed ability of
your will to raise your hand to your head or to cause your foot to make
one forward step?
If, nevertheless, you fancy you understand in what manner the will has
some of the bodily organs under its government, how, pray, do you
account for its not having all equally--the heart and liver as well as
the tongue and fingers? Without trying, you never would have discovered
that your bowels _will not_, any more than without trying you could have
known that your limbs _will_, ordinarily move in conformity with your
wishes. Neither, if one of your limbs were to be suddenly paralysed,
would you, until you tried, become aware that it would no longer move as
you wished. If there be, then, a power attached to the will, it is
plainly experience alone which apprises you of its existence; whereas
if you were independently conscious of it, you would know beforehand
precisely what it can and what it cannot effect, and would, moreover,
when you lost it, become instantly aware of your loss.
Again, and above all, does not anatomy teach us that when the mind wills
the movement of any bodily member, it 'is not the member itself which is
immediately moved, but certain intervening nerves, muscles, and animal
spirits, or possibly something still more minute and more unknown,'
through which the motion is successively propagated until it reach the
member? So that when the mind wills one event, a series of other events,
quite different and quite unthought of, take place instead; and it is
only by their means that the will's purpose is finally achieved. But how
can the mind be conscious, how can it form the remotest conception, of a
power which not only never does what the mind desires, but never does
aught of which the mind is cognisant?
And as we are thus utterly unable to perceive any power that the mind
has over the body, so are we equally unconscious of any power of the
mind over itself. We know as little of its internal nature and
constitution as we do of its mode of connection with the body. We know
by experience that at the bidding of the will ideas are continually
brought forward; but by what means they are brought forward we are
absolutely ignorant, as we are also of the reasons of the fluctuation of
mental activity, and why mental operations are more vigorous in health
than in sickness, before breakfast than after a heavy dinner or deep
carouse.
Such, on the issue immediately before us, is Hume's reasoning, to
which--though necessarily very greatly condensing it--I shall, I am
sure, be acknowledged to have conscientiously striven to do full
justice, by bringing all its points into the strongest light, and
arranging them in the most effective order. Still, with its utmost
strength thus displayed before us, we are fully warranted in asserting
_a priori_ that its whole utmost strength is weakness. If, by following
a leader who has engaged to conduct us to a certain spot, we find
ourselves at our journey's end in a quite different place, no appeal
that the guide can make to maps or finger-posts will persuade us that he
has not mistaken the way. Nor need our judgment be otherwise, even
though our guide be Hume, if, having started with him in pursuit of
truth, we are finally landed in a patent absurdity. With all due respect
for logic, we protest with Tony Lumpkin against being argufied out of
our senses, as we plainly should be if we allowed ourselves to be
persuaded that whenever we use the words _power_ or _connection_ we have
no idea thereto correspondent. Since, then, Hume tells us this, we may
be quite sure that he has been deluded by some fallacy which may be
detected by adequate search; and being, moreover, sensible that we
really have the idea our possession of which is denied by him, we may be
equally sure that the original of which the idea is a copy is similarly
discoverable. In sooth, neither the one nor the other is far to seek.
The fallacy consists simply in confusion of the definite with the
indefinite article. The original of our idea of power Hume himself
indicates even while rejecting it. Although constrained by Hume's
demonstration to confess that we cannot even conjecture of what kind is
_the_ authority which the will exercises over the limbs, we are not the
less sensible that it does exercise _an_ authority of some sort or
other, which they are unable to disobey. We know that in ordinary
circumstances our limbs will move when we wish them to move, and will
remain quiet when we wish them not to move. Nor this only. We moreover
know, or at any rate fancy we know, that they would not have moved
unless we had wished them. In examples like these of volitions followed,
as the case may be, by _premeditated_ motion or rest, we have something
more than the simple sequence observable in the succession of external
events. We do not perceive simply that, as when fire is lighted, heat is
emitted, so when the mind wills the body moves. We perceive clearly that
there must be a connection of some sort between antecedent and
consequent, without which the first certainly _would not_ and, we fancy,
_could not_ have followed the first. We perceive, in short, that the
second followed _because_ the first preceded. If fire were an animated
being, capable of forming and manifesting volitions; and if we observed
that whenever it wished to emit heat, heat was emitted; and that
whenever it wished to withhold heat, heat was withheld; and if we were
thereupon to say that fire has the power of emitting or withholding heat
at its pleasure, our words surely would not be destitute of
signification; they would certainly possess some meaning, and that a
very obvious one. And so they as certainly do when we say that the mind
has power over those bodily movements which we observe to take place and
to cease in constant conformity with its will. I am not saying that what
they mean is necessarily truth--we will come to that presently--all I
say as yet is, that they mean something, and that that something,
whether it be a real or only an imaginary perception, is perfectly
fitted to be the original of that idea of 'power' _connecting_ cause and
effect, or of 'connection' _between_ cause and effect, which Hume
maintains does not exist, because there is no original from which it
can have been copied. It matters not that we are quite ignorant of what
nature is the something from which our idea of power possessed by the
mind over the body is derived, and which, for aught we know, may reside,
not in the mind, but in the body, and may consist, not of any strength
inherent in the former, but of loyalty and docility inherent in the
latter. Just as the authority of a popular general over a
well-disciplined army is not the less real because the soldiers, every
one of whose lives is at the general's disposal, might, if so inclined,
mutiny _en masse_, so it can make no difference in the mind's power over
the body whether the mind be intrinsically able to enforce obedience, or
the limbs be so constituted as to be unable to disobey. As little does
it matter that we are also ignorant of the mode in which the mind's
behests are communicated to the members. It is not the less certain that
in some mode or other they are communicated. Neither does it signify
more that the mind does not communicate directly with the part of the
body which it desires to influence, and acts upon that part only by
means of action propagated through a series of intervening parts; or
that it is able to direct only some organs, and not others, or cannot
direct even those, if by some accident they have become seriously
deranged. A strong-armed blockhead is not the less obviously able to
pump up water because the terms 'muscular contractility' and
'atmospheric pressure' are as heathen Greek to him; or because the
pump-handle, which alone is directly moved by him, touches, not the
water itself, but only the first link in a chain of mechanism connecting
it with the water; or because, if the sucker of the pump got choked, or
the well were to dry up, it would be vain for him to go on moving the
pump-handle. Blockhead as he is, nothing of all this in the least
diminishes his conviction that as long as the pump continues in order
and there remains water in the well, he can oblige the water to rise by
moving the pump-handle; nor can anything analogous prevent the mind from
feeling that whenever, in ordinary circumstances, it wills that the
limbs be moved, the limbs not only will be moved, but cannot help being
moved accordingly. But it is simply impossible that, from the exercise
of volitions which it knows will be obeyed, the mind should not receive
the sensation of exercising causal power; and having thus got the
sensation, it has nothing to do but to copy the sensation in order to
get the idea of causal power. _Ce n'est que le premier pas qui coute_;
the first step being taken the others cost nothing. The mind having, by
introspection of its own operations, discovered what Hume, though
professing to look in the same direction, unaccountably contrived to
overlook--the idea, namely, of causal power--proceeds to apply that idea
to the connection of external phenomena. Not only do we, whenever we see
a horse or an ox walking of its own accord, infer that the animal walks
_because_ it wishes to walk; but having observed that, when a stone is
thrown into the air it invariably falls presently afterwards towards the
ground; that a magnet invariably attracts any light piece of iron placed
near it; that red-hot coals always burn; and that water always moistens,
we infer that the second constituent of each brace of phenomena takes
place _because_ of the first, meaning thereby that there is some strong
bond _connecting_ the two and _compelling_ one to follow the other. If
called upon to justify this inference, we may do so by reducing to
absurdity its only possible alternative. If there be supposed to be no
connection between two phenomena constituting one of those invariable
sequences which we are accustomed to denominate cause and effect, the
sequence which they constitute must needs be an unconnected sequence,
and the only reason for styling one of the phenomena a cause is, that it
is an antecedent which the other invariably follows. But according to
this, as has been pointed out over and over again, day would be the
cause of night, and night the cause of day, and tidal flux and reflux
likewise would be each other's causes; and Mr. J. S. Mill has therefore
proposed to interpolate a word, and to define the cause of a phenomenon
as 'the antecedent on which it (the phenomenon) is invariably and
_unconditionally_ consequent.'[30] I must, however, confess myself
unable to perceive how the definition is improved by this emendation.
There is not, and cannot possibly be, such a thing as _unconditionally_
invariable sequence, as, indeed, Mr. Mill himself virtually admits by
expressly assuming as an indispensable condition of all causation that
'the present constitution of things endure.' But if, notwithstanding the
presence of this indispensable condition, it be permissible to call any
sequence unconditionally invariable, then the sequences of night upon
day and of day upon night are such sequences, and day and night continue
consequently entitled to be styled each other's causes as much under the
amended as under the original definition. For as long as 'the present
constitution of things endures,' that is, as long as the earth continues
to revolve on its axis, and the sun continues to shine, and no opaque
substance intervenes between earth and sun, day and night will continue
to be as invariably and unconditionally each other's antecedents as
sunlight will continue to be the antecedent or concomitant of day.
True, Mr. Mill denies that the earth's diurnal motion is part of the
present constitution of things, because, according to him, 'nothing can
be so called which might possibly be terminated or altered by natural
causes:' but, if so, then neither ought sunlight to be so called, for it
too quite possibly may, nay, in the opinion of many philosophers, most
certainly will, be extinguished eventually by natural causes. If day
ought not to be called the unconditionally invariable consequent of
night merely because it would cease to be so if the earth were to cease
turning on its axis, then neither ought it to be called the
unconditionally invariable consequent of the unshrouded proximity of the
sun, inasmuch as it would cease to be thereupon consequent if the sun
were to become burnt out. If night be not, and if sunlight be, the cause
of day, the reason is not that sunlight always hitherto has been, and,
on one indispensable condition, always will be followed by day, for so
equally has hitherto been, and on the same condition will hereafter be,
night. The real reason is, that sunlight not only always has been and
will be, but also always _must_ be followed by day; that unless the
constitution of nature very materially change, wherever is sunlight day
_must_ be; whereas not only might day be, although night had never
preceded, but unless night had preceded, day must have been from the
beginning. In short, to constitute cause, invariability, however
unconditional, will not suffice. Another quality must be added, and that
quality I contend to be obligatoriness. A cause, I maintain, would not
be a cause unless its effect not only do or will, but _must_ necessarily
follow it. In common with the great unphilosophic mass of mankind, I
hold that between cause and effect there is a binding power which
constrains the one to follow the other. If asked whence we suppose that
power can have been derived, such of us, as conscious that we are 'no
very great wits,' don't mind confessing that we 'believe in a God,' will
not mind either suggesting that the power, wherever not exerted by an
animated creature, may possibly be directly from God. One thing certain
is, that inanimate matter cannot possibly possess or exercise any force
or power whatever, so that, unless matter, although apparently dead, be
really alive, attraction, cohesion, gravitation, and all its other so
called forces, being incompatible with dead inertness, must needs be
manifestations of some living, and possibly divine, power. Far from
there being any difficulty in conceiving Omnipresent Deity to be
exhibiting its might in every speck of universal space in every instant
of never-ending time, it is, on the contrary, impossible to conceive
otherwise. We cannot conceive one single minutest point in limitless
extension to be for one moment exempt from the immediate control of a
divine nature assumed to be
Diffused throughout infinity's expanse
And co-existent with eternity.
Here, indeed, we hasten to acknowledge with Hume that 'our line is too
short to fathom the immense abyss' which we have now reached. But we
need not, therefore, follow Hume to the lengths to which his insidious
mock-modesty would fain entice us. We may concede to him that 'we have
no idea of a Supreme Being but what we learn from reflection on our own
faculties,' but we need not imitate him by perversely shutting our eyes
to the evidences of an energy inherent in our own faculties, and thereby
entitle him to insist on our joining him in denying that there is any
evidence of energy in the Supreme Being. We need not, because
constrained to admit that we know no more of the essence of divine, than
we do of human, power, pretend that we cannot even conceive such a thing
as divine power. Hume's affectation of profound ignorance on the subject
must have occasioned unusual amusement in a certain quarter. The Devil
can seldom have had a more hearty grin at his darling sin than when
witnessing this peculiar exhibition of the pride that apes humility.
That Hume's ignorance was nothing but affectation is proved by his
veering completely round immediately afterwards, and in his very next
chapter, and almost in his very next page, pronouncing it to be
'universally allowed that matter in all its operations is actuated by a
necessary force, and that every natural effect is so precisely
determined by the energy of its cause that no other effect in such
particular circumstances could possibly have resulted from it.'
Throughout the same chapter he argues in the same sense, and quite
forgetting how obstinately he had just before contended that there are
absolutely no such things as connection or power at all, he defies any
one to 'define a cause without comprehending, as part of the definition,
_necessary_ connection with its effect.' So highly, indeed, does he now
rate that connecting power, whose very existence he had previously so
vehemently denied, that he professes himself unable to set any limit to
its efficacy. Even for those who should undertake to deduce from it the
impossibility of any liberty of human will, and consequently of any
human responsibility, pleading that, inasmuch as with a continued chain
of necessary causes, reaching from the first great cause of all to every
separate volition of every single human creature, it must needs be the
Creator of the world who is the ultimate author of all volitions, and
consequently solely accountable for every crime which man commits, he
affects, with exceedingly ill-sitting sanctimoniousness, to have no
better answer than that such belief, being impious, must be absurd and
cannot be true. It did not suit his purpose to point out that the
volitions of Omnipotence itself, equally with human volitions, are
necessary effects of causes--the causes in their case being the other
attributes with which Omnipotence is conjoined--and that as it is
nevertheless impossible for the volitions of Omnipotence to be otherwise
than absolutely free and uncontrolled, so there is no reason why human
volitions likewise should not, in spite of the same objection, be as
thoroughly free as our own feelings assure us they are.
Hume's sudden conversion, so amazing at first sight, from flattest
denial to positivest assertion of causal power, becomes intelligible
when he is seen immediately afterwards using his newly adopted creed as
a fulcrum whereon to rest his argumentative lever in his assault upon
Miracles. About that celebrated piece of reasoning, startling as the
avowal may sound, there is, to my mind, nothing more remarkable than its
celebrity, for, on close inspection, it will be found to be entirely
made up of (1) the demonstration of a truism, and (2) the inculcation of
a confessedly misleading rule. Not far from its commencement will be
found a definition which, if correct, would leave nothing to dispute
about. A miracle, we are told, is 'a violation of the laws of nature,'
of laws which a firm and unalterable experience has established. But if
so, _cadit quaestio_. Of course, there can be no alteration of the
unalterable. No need, of course, of further words to prove that a
miracle thus defined is an impossibility.
Let us suppose, however, the word _unalterable_ to have been used here
by a slip of the pen instead of _unaltered_, and that Hume really meant
by a miracle any alteration of what had previously appeared to be the
constant course of nature. Even so, we shall have him contending that no
amount, however great, of testimony however unimpeachable, ought to be
accepted as adequate proof of such an alteration. Of what he urges in
support of this position much may be at once dismissed as altogether
irrelevant. That the most honest witness may be the dupe of optical or
auricular illusion, or of a distorting or magnifying imagination; that
there is in many minds a natural predisposition to believe in the
marvellous, and that the love of astonishing often gives exaggerated
expression to the exaggerations of the fancy; that self-interest and
religious zeal often furnish additional motives for mendacity, and that
testimony, even when sincere at first, is apt to become corrupted at
every stage as it passes from hand to hand, or is committed to
paper--all this, together with any further enumeration of circumstances
calculated to invalidate testimony, is quite beside the real question.
It merely proves what no one needs to have proved, the propriety, viz.,
of weighing evidence and balancing adverse probabilities; and even
though it proved in addition that of all the so-styled miracles on
record, there is not a single one the evidence for which is sufficient,
it would still prove nothing to the purpose. For Hume is arguing against
the credibility, not of any miracles in particular, but of all miracles
in general, those included the witnesses for which are of indisputable
intelligence and undisputed veracity. Be the quality of the testimony
what it may, no quantity of it, according to him, can be sufficient.
This is the essence of his thesis, the only part of it in which there
is any novelty, and in behalf of this part all that he has to say may be
resolved into a sophism, followed by a repetition of the same begging of
the question, as is involved in his afore-cited definition of a miracle.
In substance it runs as follows. All testimony is at best but a
description of the results of sensible experience--of observations of
the senses--but the most faithful description must needs be a less vivid
presentation of truth than the reality described. A single original is
better evidence than any number of copies. Your own personal experience
is more trustworthy than any number of mere records of the experience of
other people, and where the two conflict, the former always deserves
preference. Now the personal experience of each one of us assures us
that many sets of natural phenomena take place in perfectly invariable
sequences, in sequences so invariable as to appear to be, and to be
familiarly spoken of as, manifestations or operations of certain
inflexible laws of nature. Within our experience there has never been a
single deviation from any such law. Wherefore, though all the rest of
mankind should unite in asserting that they have observed such a
deviation, we ought not to believe them. Even though, for example--the
example, however, being not Hume's, but my own--we were, on leaving home
some morning, to hear on all sides that, while we were yet in bed, the
sun was seen to rise in the west instead of the east, and though we
found the statement repeated in the 'Times' and 'Daily News,' and
presently afterwards saw it posted up at the Exchange as having been
flashed by electric wire from New York and Kurrachee, we are not for a
moment to doubt that these reiterated and mutually corroborative
statements are utterly false. For, numerous and consistent as they may
be, they are but copies of the experience of other people, while,
although we may have to oppose to them only our own single experience,
still that single experience is original, and therefore of more worth.
The value, moreover, of any experience is, irrespective of originality,
determined by the difference in number between the results of opposite
kinds which it has discovered. The smaller number is deducted from the
larger, and the balance represents the probability that the results
which have most frequently occurred hitherto will continue to occur
henceforward. The larger the deduction thus to be made, the smaller the
probability, and _vice versa_; and when the deduction is _nil_, or when
there has hitherto been complete uniformity, the probability becomes
virtual certainty. When two original experiences are opposed to each
other, their respective values, ascertained in the same manner, are
compared, and trust is reposed in one or the other accordingly. Now,
according to these principles, difficult as it might be in the case
supposed for any one to conceive what motive all the rest of the world
could have for lying, it would be still more difficult to believe them
to be speaking truth. For why do we ever believe anything that anyone
says? Why but because we have learnt by experience that, when people
have no apparent motive for lying, they commonly do speak the truth? But
the same experience which has taught us this has taught us likewise that
people do now and then lie without apparent motive. At best, therefore,
there is never more than a probability that people are speaking the
truth, while in this instance, the supposition that they might be
speaking the truth would imply that there may be a truth against which
there is proof amounting to certainty. For what they affirm is that
something has happened the very reverse of what has invariably happened
before in the same circumstances. Is it not infinitely more likely that
people should be lying as they have often done before, than that the
invariable course of nature should have undergone a variation? With
evidence on the one side that has never yet deceived, with no evidence
on the other save what has often proved deceptive, how can we hesitate
which to accept? Even though the unanimity of testimony be such as might
otherwise be deemed complete proof, it is here met by absolutely
complete proof in the shape of a law of nature. The greater probability
overwhelms the lesser. The stronger proof annihilates the weaker,
leaving none of it behind, so that whoever still persists in believing
that a law of nature has been violated, must be content to do so without
one particle of proof. No quantity of testimony can furnish the smallest
proof of a miracle unless the falsehood of the testimony would be a
greater departure from antecedent uniformity--in other words, would be a
greater miracle--than the miracle which it attests. Unfortunately it is
but too notorious that there is not, and never has been, such a thing as
uniform truthfulness of testimony to depart from.
Such, unless most unintentionally injured by compression, is Hume's
famous argument against miracles, of which the author was sufficiently
proud to boast openly that in it he had discovered what 'will be useful,
as long as the world endures,' as 'an everlasting check to all kinds of
superstitious delusion,' but which, as I nevertheless venture to repeat,
is compounded in about equal moieties of transparent sophism and
baseless assumption. For is it not the veriest juggle of words to insist
on the necessary inferiority of copies to an original, without adverting
to the indispensable proviso that the original with which the copies
are compared should be the original from which the copies have been
taken? May not a copy of Leonardo Da Vinci's 'Last Supper' quite
possibly be equal in force and vividness of expression to the original
painting by Benjamin West bearing the same name? Might it not be wise to
trust rather to an Airy, or a De la Rue, or a Lockyer's account of what
he had observed during a solar eclipse than to your own immediate
observations on the same occasion? Besides, this first branch of Hume's
argument, if sound, would tell quite as much for, as against, miracles,
rendering it equally incumbent on actual witnesses to believe, as on all
but actual witnesses to disbelieve. If you are always to prefer your own
original experience to mere descriptions given by other people of
theirs, then should it happen to be yourself to whom the sun appeared in
the west at an hour when, according to custom, he ought to have been in
the east, you are not to allow the protestations of any number of
persons who, happening at the time to have been looking the other way,
saw the sun in his usual place, to persuade you that what you saw was a
mock sun or an _ignis fatuus_. Rather than imagine that your own senses
can have deceived you, you are to suppose that all about you are in a
league to deceive you. For precisely the same reason for which you
should reject even universal testimony in favour of a miracle which you
have not witnessed, you are equally to reject universal testimony in
opposition to a miracle the similitude of which you have witnessed.
Or is it possible for a question to be more distinctly begged than when,
to the question whether a miracle has occurred, it is answered that a
miracle is not a miracle unless there be uniform experience against it;
that uniformly adverse experience is direct and full proof against
anything; and that therefore there must always be full proof against
miracles? What is here taken for granted to be full proof is the very
thing requiring to be proved. If past uniformity really be a pledge for
continued uniformity, of course there can be no departure from
uniformity. If the whole question does not at once fall to the ground,
it is because no question has ever really arisen. But what shadow of
pretext is there for treating an hitherto unvaried course of events as
necessarily invariable? From past experience we have deduced what we are
pleased to call _laws_ of nature, but it is morally impossible that we
can seriously think, whatever we are in the habit of saying, that these
laws are self-denying ordinances whereby nature's God has voluntarily
abdicated part of His inalienable prerogative. The utmost efficacy we
are warranted in ascribing to them is that of lines marking certain of
the courses within which God's providence is pleased to move. But how
can we pretend to know for how long a season such may continue to be the
divine pleasure? How do we know that the present season may not be the
first of an alternating series, and that it may not at any moment
terminate, and be succeeded by one of an opposite character? What though
we have some shadow of historical evidence that most physical phenomena
have been going on in much the same order for some six thousand years,
is that a basis whereon to theorise with regard to the proceedings of
Him in whose sight one day is as a thousand years and a thousand years
as one day? Might not as well some scientific member of an insect tribe
of ephemera, whom ancestral tradition, confirmed by personal experience,
had assured that an eight-day clock had already gone on for six days,
pronounce it to be a law of the clock's nature that it should go on for
ever without being again wound up? Would the insect philosopher's
dogmatism be one whit less absurd than that of those human ephemera who
so positively lay down the law about the clockwork of the universe?
Those laws of nature to which unerring regularity and perpetuity of
operation are so confidently attributed, may they not, perchance, be but
single clauses of much farther reaching laws, according to whose other
provisions the force of these isolated clauses may, in novel
combinations of circumstances, be counteracted by some latent and
hitherto unsuspected force? Or is it not, at all events, open to their
divine promulgator to suspend their operation at his pleasure? May it
not conceivably have been preordained that the globe of our earth, after
revolving for a given number of ages, in one direction, shall then, like
a meat-jack, or like an Ascidian's heart,[31] reverse its order of
procedure, and commence a contrary series of revolutions? Or might not
He who prescribed to the earth its rotatory movement, will that the
rotation should for some hours cease, and that the sun should in
consequence seem to stand still, as it is recorded to have done at the
command of Joshua? Improbable as these suppositions may be, who that has
not been taken into counsel by his Creator can presume to say that they
may not be correct? The events which they involve are not inconceivable,
and whatever is not utterly inconceivable may possibly occur, however
numerous the chances against its occurrence. It is not then the fact
that 'past experience,' however unvaried, affords full proof of the
future existence of any event, or constitutes certainty against the
future existence of the reverse of that event. Completest uniformity of
experience cannot create a certainty by which any opposite probability
would be completely annihilated. It only creates a probability which,
however great, is still only a probability, and which would become a
smaller probability by deduction from it of any opposite probability.
But mere probability, however great, always includes some doubt as to
its own correctness, some suspicion that its opposite may possibly be
correct. How much soever, therefore, uniform experience may vouch for
the inviolability of natural laws, it always remains possible for those
laws to be violated, and, as miracles are nothing else but violations of
natural laws, it always remains possible for miracles to happen. But
since miracles are possible, testimony to their occurrence may, with
equal possibility, be true, and no further refutation can, I submit, be
needed for an argument which insists that all such testimony should be
set aside without enquiry as self-evidently false.
Had Hume been content to insist that testimony in favour of miracles
should never be received without extreme doubt and hesitation, his
lesson might well have passed without further objection than that of its
being superfluous for any one with sense enough to profit by it. Nor
might it have been easy to discover a flaw in his logic, although he had
gone so far as to maintain that no one of the miracles as yet on record
is either adequately attested, or would, even if it had undoubtedly
occurred, afford sufficient evidence of any religious truth. The best
and only adequate evidence for any religious creed is the satisfaction
which it affords to the soul's cravings and promises to the soul's
aspirations; and no rational Christian would be at all the more disposed
to turn Mussulman, even though it should be demonstrated to his entire
conviction that Christ did not raise Lazarus from the dead, and that
Mahomet did turn the hill Safa into gold, instead of prudently confining
himself to boasting that he could have effected the transmutation if he
had thought proper. But for the purpose which Hume had in view, it was
necessary to establish, not merely the doubtfulness, but the absolute
falsehood of the miracular testimony on which, in his opinion, 'our holy
religion' rests, in order that the character of the superstructure being
inferred from that of the foundation, both might be condemned together.
There is, however, an irreligious as well as a religious fanaticism,
and, though it is difficult, while looking at Hume's portrait, to credit
the owner of that plump, good-humoured face with feeling of any sort
warm enough to be termed fanatical, it is humiliating to note from his
example into what strange inconsistency the coolest and calmest judgment
may be warped by irreligious prejudice. Having not long before, in order
to disparage _natural_ religion, emphatically denied the existence of
any causal connection between successive events, he now, in order
equally to discredit the very possibility of _revealed_ religion,
tacitly assumes that same connection, not simply to exist, but to be of
an efficacy which no disturbing forces can impair. Admitting that 'the
Indian prince who refused to believe the first relations concerning the
effects of frost' was wrong in his belief, Hume will have it that the
prince nevertheless 'reasoned justly.' Although recognising truth to be
the sole worthy object of quest, he yet enjoins rigid adherence to a
rule which he is aware must inevitably lead to frequent error.
Rather strikingly contrasted, in respect of execution, with Hume's
chapter on Miracles, comes the one next in order on a Providence and a
Future State, which, for the skill with which the fallacy involved in it
is disguised, may be regarded as quite a masterpiece of false reasoning.
Among its leading propositions there is but one which does not command
immediate assent. That we can argue but from what we know; that of
causes, known to us only by their effects, our estimate ought to be
exactly proportioned to the effects; that of a Creator manifested only
by His works, no higher qualities, no greater degrees of power,
intelligence, justice, or benevolence, can be confidently
predicated--whatever be conjectured--than are apparent in his
workmanship: all this, on one moment's reflection, is perceived to be
indisputable. Needs must it be, however reluctantly, admitted that
nothing can be more illogical than to return back to the cause, and
infer from it other effects beyond those by which alone it is known to
us, or to infer from creative attributes, distinctly manifested, the
existence of other and not apparent attributes, endowed with some
efficacy additional to that possessed by the former. But does it hence
follow that faith in a superintending Providence is so mere a matter of
'conceit and imagination,' a faith so absolutely irrational as Hume
considered it? A candid examination of God's works will warrant us in
coming to a widely different conclusion. Among those works is man--a
being who, in spite of the utter insignificance of his greatest
_performances_, is capable of forming most exalted _conceptions_ of
justice, benevolence, and goodness in general, and of feeling the most
eager desire to act up to his own ideal. If the divine notions of
goodness in its several varieties be not identical with the human, it
can only be because they are superior; and so, too, of the divine love
of, and zeal for, goodness. It cannot be that the Creator is inferior to
the creature in virtues which the creature derives from Him alone.
Demonstrably, therefore, God is good and just in the very highest degree
in which those qualities can be conceived by man. Demonstrably, too,
since the universe is the work of His hands, He must be possessed of
power which, if not necessarily unbounded, is at least as boundless as
the universe. Thus, rigidly arguing from effects to causes, and
scrupulously proportioning the one to the other, man sees imaged on the
face of creation a creator, both realising his highest conception of
goodness, and wielding measureless might. Is not such a being worthy to
be looked up to, and confided in, and adored and loved as a
superintending providence? Is not faith in such a providence not simply
not irrational, but the direct result of a strictly inductive process?
And would it be an irrational stretch of faith sanguinely to hope, if
not implicitly to believe, that an union of infinite justice with
measureless might may, in some future stage of existence, afford
compensation for the apparently inequitable distribution of good and
evil which, according to all experience, has hitherto taken place among
human beings?
Were it desirable to amplify the apology with which this paper
commenced, some additional justification of the freedom of the
foregoing criticisms might be found in hints thrown out by Hume in
various parts of the treatise which we have been examining, and
particularly in its concluding chapter, that in many of his most
startling doctrines he was but half in earnest. Hume's temperament, too
cool for fanaticism, had yet in it enough of a certain tepid geniality
to save him from becoming a scoffer. The character which he claims for
himself, and somewhat ostentatiously parades, is that of a sceptic or
general doubter--a character in which, when rightly understood, there is
nothing to be ashamed of. To take nothing on trust, to believe nothing
without proof, to show no greater respect for authority than may consist
in attentive and candid examination of its statements, to accept only
verified facts as bases for reasoning on matters of fact and
existence--these are golden rules of philosophical research, principles
in which lies the secret of all real progress in any of the higher
departments of science. By Hume they were adopted _con amore_, and with
keen appreciation, not more of their practical utility, than of the
sport which he perceived them to be capable of yielding. His serious
purpose was to unmask the numberless pretences which in politics,
political economy, metaphysics, morals, and theology he found
universally current as gospel truths; to expose the ambiguity and
contradictions latent in popular thought, and in the popular forms of
expression which are so apt to be mistaken for thought, and to indicate
the only safe mode of investigation and the only trustworthy tests of
genuine knowledge; his favourite amusement to put time-honoured
commonplaces on the rack, and demanding their _raison d'etre_, to pass
on them summary sentence of extinction if they failed to account
satisfactorily for their existence. Unfortunately, in his keen
enjoyment of the fun of the thing, he not unfrequently overlooked the
solid interests at stake. Like a huntsman who, for the sake of a better
run, should outrace his quarry, or who, seeing that the dogs were close
upon the hare, should, in order to prolong the chase, start a fresh
hare, kept till then snug at his saddle-bow, so Hume, in the excitement
of metaphysical pursuit, instead of stopping to gather up whatever
verified affirmations came in his way, would prefer to follow any new
negation that he espied, or, if momentarily accepting any affirmation as
established, would proceed forthwith to affirm its direct opposite with
the view of neutralising both. In this, his practice resembled that of
metaphysicians in general, who take a singular delight in setting
themselves riddle after riddle, which they either assume to be
hopelessly insoluble, or which they no sooner solve than they use the
solution as the subject of another riddle involving its predecessor in
redoubled perplexity. Now, little harm, and little, perhaps, of anything
but good, might thereby be done if the lovers of this game were content
to play it by themselves, without inviting others to join who are
constitutionally unfit for such intellectual wrestling. But mental
exercises may to philosophers be health and invigorating sport, and yet
be death to the multitude; and Hume, as an Utilitarian, stands
self-condemned for making ordinary people uncomfortable by challenging
them to disputations confessedly leading no whither, and bewildering
them with confessedly 'vain and profane babblings, and strivings after
words to no profit, but to subverting of the hearers, and overthrow of
the faith of some.' And it is as poor an excuse for this wanton
tampering with other people's creeds, as it is poor amends for its
mischievous consequences, that Hume offers when, after watching for a
while his puzzled disciples blown about by the winds of adverse doctrine
that he has let loose upon them, he proceeds to rally them on their
'whimsical condition,' which he speaks of as a mere laughing matter got
up chiefly for amusement. It is only an aggravation of offence that,
while, on the one hand, he solemnly pronounces everything to be 'a
riddle, an enigma, an inexplicable mystery,' he, on the other hand,
cheerily exhorts us not to suffer the 'doubts raised by philosophy to
affect our actions.' 'Nature,' he says, 'is always too strong for
principles, will always maintain her rights, and prevail, in the end,
against all reasoning whatever.' 'The great subverter of Pyrrhonism,' he
continues, 'is actual employment and the occupations of common life,' in
presence of which its overstrained scruples 'vanish like smoke.'
Although real knowledge consists solely in knowing that we know nothing,
and in doubting everything, and although sceptics may 'justly triumph'
in principles which lead them to deny even the attraction of
gravitation, still they had better beware how they act on these
principles, lest by stepping unconcernedly out of window they come
fatally to grief on the stones below, and so the sect and its tenets be
annihilated together. So, or to such effect, Hume: but how can there be
just ground for pride in speculations which, as their own professors
admit, would, on the first attempt to reduce them to practice, be
shattered to pieces by hard facts? That cannot possibly, even on Hume's
recommendation, be accepted as metaphysical truth, which flatly
contradicts common sense, nor can there be any unbecoming
self-confidence in seeking, even though Hume pronounce the search
hopeless, for metaphysical truth, with which common sense may be
reconciled.

in that year M. von Hasselt, happening to examine a transparent animal
