In the greater number of our successions of momentary feelings,

then, when no reference is made to former states of the mind, the

consciousness is obviously nothing more than the simple momentary

feeling itself as it begins and ceases; and when there is a reference

to former states of the mind, we discover on analysis only a

remembrance, like all our other remembrances, and a feeling of common

relation of the past and the present affection of the mind to one

permanent subject. It is the belief of our continued identity which

involves this particular feeling of relation of past and present

feelings; and consciousness, in this sense of the term, is only a word

expressive of that belief.

That the fragrance of a rose, the sound of a flute, and in general

all the other objects of sense, might have excited precisely the

same immediate sensations as at present, Doctor Reid admits, though

the belief of our personal identity had not been impressed upon us;

for he ascribes this belief to an instinctive principle only, and

acknowledges, that there is nothing in our sensations themselves, from

which any such inference could be drawn by reason. If, then, this

instinctive belief of identity had not been, as at present, a natural

law of human thought,--operating irresistibly on the remembrance of

our different feelings, we should have had no notion of _self_, of

_me_, the sentient and thinking being, who exists at the present

moment, and who existed before the present moment:--and what, then,

would have been the consciousness, accompanying, and different from,

our sensations, when they merely flashed along the mind and vanished?

The most zealous defender of consciousness, as a separate intellectual

power, must surely admit, that, in such circumstances, it would have

been nothing more than _sensation_ itself. It is the belief of our

_identity_ only, which gives us the notion of _self_, as the subject

of various feelings, and it is the notion of self, as the subject of

various former feelings, which leads us to regard the consciousness of

the moment, as different from the sensation of the moment; because it

suggests to us those former feelings, which truly were different from

it, or at least that _subject mind_, which unquestionably existed

before the present sensation.

If it be said, that the faculty of consciousness is nothing more

than this reference to the past, and consequent belief of identity,

we may, in that case, very safely admit its existence; though the

classification of it, as a peculiar intellectual power, would in that

case be a most singular anomaly in arrangement, and would involve

a very absurd, or at least a very awkward use of a term. To assert

this signification of it, however, would be to admit everything for

which I have contended. But it certainly is not the sense, which has

been attached to it by philosophers; and indeed, in _this_ sense,

_consciousness_, instead of having for its objects, as Doctor Reid

says, _all_ “our present pains, our pleasures, our hopes, our fears,

our desires, our doubts, our thoughts of every kind; in a word, all the

passions, and all the actions and operations of our own mind, while

they are present,” would be limited to the comparatively few, of which

the consideration of our personal identity forms a part. In far the

greater number of our feelings, as I have already said, the sensation

dies away, almost in the moment,--not indeed, without being enjoyed or

suffered, but without any reference to self, as the subject of various

feelings, or remembrance of any prior state of mind, as distinct

from the present. The belief of our identity, is surely not the only

belief that arises from an instinctive principle; and if its existence

entitle us, in our systematic arrangements, to the possession of a new

intellectual power, every other belief that arises instinctively from a

principle of our constitution, must give us a similar title to enlarge

the catalogue of our faculties. The never-failing and instant faith,

by which we expect, without the slightest doubt of the similarity

of the future, that events will continue to follow each other, in

the same order as at present,--that bodies will fall to the ground,

fire burn, food satisfy the craving of our appetite--that immediate

intuitive principle of belief, on which all our foresight depends,

and according to which we regulate our whole conduct in providing

for the future,--should certainly, in that case, be ascribed by us

to some peculiar intellectual power, for which it would be easy to

invent a name. It is not, by any inference of our reason, we believe,

that the sound of a flute which preceded the fragrance of a rose, and

the fragrance of a rose which followed the sound of a flute, excited

sensations that were states of the same identical mind; for there is

nothing, in either of the separate sensations, or in both together,

from which such an inference can be drawn; and yet, notwithstanding the

impossibility of inferring it, we believe this, at least as strongly,

as we believe any of the conclusions of our reasoning. In like manner,

it is not by any inference of reason we believe, that fire will warm

us to-morrow, as it has warmed us to-day; for there is nothing, in the

fire of to-day, or in the sensation of warmth, considered as a mere

sequence of it, from which the succession of a similar sensation to

the fire of to-morrow can be inferred; yet we also rely on this future

sequence, at least as strongly, as we believe any of the conclusions

of our reasoning. In both cases the parallel is complete; and in both,

the evidence of a particular intellectual faculty, must consequently be

alike,--or in neither is there sufficient evidence of such a power.

There is, indeed, one other sense, in which we often talk of our

consciousness of a feeling, and a sense, in which, it must be allowed,

that the consciousness is not precisely the same as the feeling

itself. This is, when we speak of a feeling, not actually existing at

present, but _past_--as when we say, that we are conscious of having

seen, or heard, or done something. Such a use of the term, however,

is pardonable only in the privileged looseness and inaccuracy of

familiar conversation: the consciousness, in this case, being precisely

synonymous with remembrance or memory, and not a power, different

from the remembrance. The _remembrance_ of the feeling, and the vivid

_feeling_ itself, indeed, are different. But the remembrance, and the

consciousness of the remembrance, are the same--as the consciousness of

a sensation, and the sensation, are the same; and to be conscious that

we have seen or spoken to any one, is only to remember that we have

seen or spoken to him.

Much of this very confusion with respect to memory, however, I have no

doubt, has been always involved in the assertion of consciousness as

a peculiar and distinct power of the mind. When we think of feelings

long past, it is impossible for us not to be aware that our mind is

then truly retrospective; and memory seems to us sufficient to account

for the whole. But when the retrospect is of very recent feelings--of

feelings, perhaps, that existed as distinct states of the mind, the

very moment before our retrospect began, the short interval is

forgotten, and we think that the primary feeling, and our consideration

of the feeling, are strictly simultaneous. We have a sensation;--we

look instantly back on that sensation,--such is consciousness, as

distinguished from the feeling that is said to be its object. When it

is any thing more than the sensation, thought, or emotion, of which

we are said to be conscious, it is a brief and rapid retrospect. Its

object is not a present feeling, but a past feeling, as truly as when

we look back, not on the moment immediately preceding, but on some

distant event or emotion of our boyhood.

After thus distinguishing all that is truly _present_ in consciousness,

from common remembrance, I surely need not undertake, at any length, to

distinguish it from that peculiar species of remembrance, which goes

under the name of _conscience_; though their similar etymology may have

a slight tendency to mislead. _Conscience_ is our _moral memory_;--it

is the _memory of the heart_, if I may apply to it a phrase, which, in

its original application, was much more happily employed, by one of the

deaf and dumb pupils of the Abbe Sicard, who, on being asked what he

understood by the word _gratitude_, wrote down immediately, “_Gratitude

is the memory of the heart_.”

The power of conscience does, indeed, what consciousness does not. It

truly doubles all our feelings, when they have been such as virtue

inspired; “Hoc est vivere _bis_, vita posse priore frui;” and it

multiplies them in a much more fearful proportion, when they have

been of an opposite kind--arresting, as it were every moment of

guilt, which, of itself, would have passed away, as fugitive as our

other moments, and suspending them forever before our eyes, in fixed

and terrifying reality. “Prima et maxima peccantium est pæna,” says

Seneca, “_peccasse_; nec ullum scelus, illud fortuna exornet muneribus

suis, licet tueatur ac vindicet, impunitum est quoniam sceleris in

scelere supplicium est.”[43] “The first and the greatest punishment

of guilt, is to have been guilty; nor can any crime, though fortune

should adorn it with all her most lavish bounty, as if protecting and

vindicating it, pass truly unpunished; because the punishment of the

base or atrocious deed, is in the very baseness or atrocity of the deed

itself.” But this species of memory, which we denominate _conscience_,

and, indeed, every species of memory, which must necessarily have for

its object the past, is essentially different from the consciousness

which we have been considering, that, in its very definition, is

limited to _present_ feelings, and of which, if we really had such an

intellectual power, our moral conscience would, in Dr Reid's sense of

the term, be an _object_ rather than a part.

Consciousness, then, I conclude, in its simplest acceptation, when

it is understood as regarding the present only, is no distinct power

of the mind, or name of a distinct class of feelings, but is only

a general term for all our feelings, of whatever species these may

be, sensations, thoughts, desires;--in short, all those states or

affections of mind, in which the phenomena of mind consist; and when

it expresses more than this, it is only the remembrance of some

former state of the mind, and a feeling of the relation of the past

and the present as states of one sentient substance. The term is very

conveniently used for the purpose of abbreviation, when we speak of the

whole variety of our feelings, in the same manner as any other general

term is used, to express briefly the multitude of individuals that

agree in possessing some common property of which we speak; when the

enumeration of these, by description and name, would be as wearisome to

the patience, as it would be oppressive to the memory. But still, when

we speak of the evidence of consciousness, we mean nothing more, than

the evidence implied in the mere existence of our sensations, thoughts,

desires,--which is utterly impossible for us to believe to be and not

to be; or, in other words, impossible for us to feel and not to feel at

the same moment. This precise limitation of the term, I trust, you will

keep constantly in mind in the course of our future speculations.

LECTURE XII.

ON CONSCIOUSNESS, CONTINUED,--ON MENTAL IDENTITY,--IDENTITY

IRRECONCILABLE WITH THE DOCTRINE OF MATERIALISM,--DIFFERENCE BETWEEN

PERSONAL IDENTITY AND MENTAL IDENTITY,--OBJECTIONS TO THE DOCTRINE OF

MENTAL IDENTITY STATED.

In my last Lecture, Gentlemen, I brought to a conclusion my remarks

on the _nature_ and _objects_ of _Physical Inquiry_,--the clear

understanding of which seemed to me, essentially necessary before

we could enter with any prospect of success, on the physiological

investigation of the Mind.

We then opened our eyes, as it were on the great field of thought

and passion, and on all the infinite variety of feelings, which, in

assemblages more or less complex, and in colours more or less brilliant

or obscure, it is every moment presenting to our internal glance. The

very attempt to arrange these transient feelings as phenomena of the

mind, however, implies evidently some consideration of the nature of

that varied consciousness in which they consist, and of the identity

of the permanent substance, as _states_ of _which_ we arrange them. My

last Lecture, therefore, was devoted to this primary consideration of

_consciousness_,--which we found reason to regard, not as any separate

and peculiar faculty of the mind, of which our various feelings are,

to use Dr Reid's expression, _objects_, and which is, therefore,

to be added, in every instance, to the separate pleasures, pains,

perceptions, remembrances, passions, that constitute the momentary

states of the mind,--but merely as a short general term, expressive

of all these momentary states in reference to the permanent subject

_mind_. The sensation of fragrance, for example, is the consciousness

of one moment, as the remembrance of that sensation, or some

other sensation, is, perhaps, the consciousness of the succeeding

moment;--the mind, at every moment, existing in one precise state,

which, as one state can be accurately denoted only by one precise name,

or by names that are synonymous, not by names that are significant of

total diversity.

All which we know, or can be supposed to know, of the mind, indeed, is

a certain _series_ of these states or feelings that have succeeded each

other, more or less rapidly, since life began; the sensation, thought,

emotion, of the moment being one of those states, and the supposed

consciousness of the state being only the state itself, whatever it may

be, in which the mind exists at that particular moment; since it would

be manifestly absurd to suppose the same indivisible mind to exist at

the very same moment in two separate states, one of sensation, and one

of consciousness. It is not simply because we _feel_, but because we

remember some _prior_ feeling, and have formed a notion of the mind

as the permanent subject of different feeling, that we conceive the

proposition, “I am _conscious_ of a sensation,” to express more than

the simple existence of the sensation itself; since it expresses,

too, a reference of this to the same mind which had formerly been

recognised as the subject of other feelings. There is a remembrance

of some former feeling, and a reference of the present feeling to the

same subject; and this mere remembrance, and the intuitive belief of

identity which accompanies remembrance, are all that philosophers, by

defective analyses, and a little confusion of language and thought,

have asserted to be the result of a peculiar mental faculty, under the

name of consciousness;--though consciousness, in this sense, far from

embracing all the varieties of feeling,--that, in the greater number of

instances, begin and cease, without any accompanying thought of that

permanent substance to which the transient feeling is referable,--must

be limited to the comparatively few, in which such a reference to self

is made.

Consciousness, in short, whenever it is conceived to express more than

the present feeling, or present momentary state of the mind, whatever

that may be, which is said to be the _object_ of consciousness,--as if

it were at once something different at every moment from the present

state or feeling of the mind, and yet the very state in which the mind

is at every moment supposed to exist,--is a retrospect of some _past_

feeling, with that belief of a common relation of the past and present

feeling to one subject mind, which is involved in the very notion,

or rather constitutes the very notion, of personal identity,--and

all which distinguishes this rapid retrospect from any of the other

retrospects, which we class as remembrances, and ascribe to memory

as their source, is the mere briefness of the interval between the

feeling that is remembered, and the reflective glance which seems to

be immediately retrospective. A feeling of some kind has arisen, and

we look instantly back upon that feeling; but a remembrance is surely

still the same in nature, and arises from the same principle of the

mental constitution, whether the interval which precedes it be that of

a moment, or of many hours, or years.

I now then proceed, after these remarks on our consciousness as

momentary, to a most important inquiry, which arises necessarily from

the consideration of the successions of our momentary consciousness,

and must be considered as involved in all our attempts to arrange

them,--the inquiry into the _Identity_ of the Mind, as truly _one_ and

_permanent_, amid all the variety of its fugitive affections.

In our examination of this very wonderful coincidence of sameness and

diversity, I shall confine my remarks to the phenomena which are purely

mental, omitting the objections drawn from the daily waste and daily

aliment of our corporeal part, the whole force of which objection may

be admitted, without any scruple by those who contend for the identity

only of the thinking principle; since the individuality of _this_

would be as little destroyed, though every particle of the body were

completely changed, as the individuality of the body itself would be

destroyed, by a change of the mere garments that invest it. The manner

in which the mind is united to a system of particles, which are in a

perpetual state of flux, is, indeed, more than we can ever hope to

be able to explain; though it is really not more inexplicable, than

its union to such a system of particles would be, though they were to

continue forever unchanged.

I may remark, however, by the way, that though the constant state of

flux of the corporeal particles furnishes no argument against the

identity of the principle which feels and thinks, if feeling and

thought be states of a substance, that is essentially distinct from

these changing particles, the unity and identity of this principle,

amid all the corpuscular changes,--if it can truly be proved to be

identical,--furnish a very strong argument, in disproof of those

systems which consider thought and feeling as the result of material

organization. Indeed the attempts which have been seriously made by

materialists to obviate this difficulty, involve, in every respect,

as much absurdity, though certainly not so much pleasantry, at least

so much _intentional_ pleasantry, as the demonstrations, which the

Society of Freethinkers communicated to Martinus Scriblerus, in their

letter of greeting and invitation. The arguments, which they are

represented as urging in this admirable letter, ludicrous as they may

seem, are truly as strong, at least, as those of which they are a

parody; and indeed, in this case, where both are so like, a very little

occasional change of expression is all which is necessary, to convert

the grave ratiocination into the parody, and the parody into the grave

ratiocination.

“The parts (say they) of an animal body,” stating the objection which

they profess to answer, “are perpetually changed, and the fluids

which seem to be the subject of consciousness, are in a perpetual

circulation; so that the same individual particles do not remain in

the brain; from whence it will follow, that the idea of individual

consciousness must be constantly translated from one particle of matter

to another, whereby the particle A, for example must not only be

conscious, but conscious that it is the same being with the particle B

that went before.

“We answer, this is only a fallacy of the imagination, and is to be

understood in no other sense than that maxim of the English law,

that the _king never dies_. This power of thinking, self-moving, and

governing the whole machine, is communicated from every particle to its

immediate successor, who, as soon as he is gone, immediately takes upon

him the government, which still preserves the unity of the whole system.

“They make a great noise about this individuality, how a man is

conscious to himself that he is the same individual he was twenty years

ago, notwithstanding the flux state of the particles of matter that

compose his body. We think this is capable of a very plain answer, and

may be easily illustrated by a familiar example.

“Sir John Cutler had a pair of black worsted stockings, which his maid

darned so often with silk, that they became at last a pair of silk

stockings. Now supposing those stockings of Sir John's endued with some

degree of consciousness at every particular darning, they would have

been sensible, that they were the same individual pair of stockings

both before and after the darning; and this sensation would have

continued in them through all the succession of darnings; and yet after

the last of all, there was not perhaps one thread left of the first

pair of stockings; but they were grown to be silk stockings, as was

said before.

“And whereas it is affirmed, that every animal is conscious of some

individual self-moving, self-determining principle; it is answered,

that, as in a House of Commons all things are determined by a

_majority_, so it is in every animal system. As that which determines

the house is said to be the reason of the whole assembly; it is no

otherwise with thinking beings, who are determined by the greater force

of several particles, which, like so many unthinking members, compose

one thinking system.”[44]

The _identity_, which we are to consider, is, as I have already said,

the identity only of the principle which feels and thinks, without

regard to the changeable state of the particles of the brain, or of

the body in general. This unity and permanence of the principle,

which thinks, if we had still to invent a phrase, I would rather

call _mental_ identity, than _personal_ identity, though the latter

phrase may now be considered as almost fixed by the general use of

philosophers. On no system can there be this absolute identity, unless

as strictly mental; for, if we adopt the system of materialism, we

must reject the absolute lasting identity of the thinking principle

altogether; and if we do not adopt that system, it is in the _mind_

alone that we must conceive the identity to subsist. The _person_, in

the common and familiar meaning of the term, though involving the mind,

is yet more than the mere mind; and, by those, at least, who are not

conversant with the writings of philosophers on the subject, sameness

of person would be understood as not _mental_ only, but as combining

with the absolute identity of the mind, some sort of identity of the

body also; though, it must be confessed, that, in its application to

the body, the term _identity_ is not used with the same strictness,

as in its application to the mind; the bodily identity being not

absolute, but admitting of considerable, and ultimately, perhaps,

even of total, change, provided only the change be so gradual, as

not to be inconsistent with apparent continuity of existence. Still,

however, identity of _person_, at least in the popular notion of it, is

something more than identity of mind.

“All mankind,” says Dr Reid, “place their personality in something,

that cannot be divided or consist of parts. A part of a person is a

manifest absurdity.

“When a man loses his estate, his health, his strength, he is still the

same person, and has lost nothing of his personality. If he has a leg

or an arm cut off, he is the same person he was before. The amputated

member is no part of his person, otherwise it would have a right to

a part of his estate, and be liable for a part of his engagements;

it would be entitled to a share of his merit and demerit, which is

manifestly absurd. A person is something indivisible, and is what

Leibnitz calls a monad.”[45]
