substances, as well as animal identity is preserved in the change of

material substances, or variety of particular bodies: unless they wil

say, it is one immaterial spirit that makes the same life in brutes, as

it is one immaterial spirit that makes the same person in men; which the

Cartesians at least wil not admit, for fear of making brutes thinking

things too.

15. Whether in Change of thinking Substances there can be one Person.

But next, as to the first part of the question, Whether, if the same

thinking substance (supposing immaterial substances only to think) be

changed, it can be the same person? I answer, that cannot be resolved

but by those who know there can what kind of substances they are that do

think; and whether the consciousness of past actions can be transferred

from one thinking substance to another. I grant were the same

consciousness the same individual action it could not: but it being a

present representation of a past action, why it may not be possible,

that that may be represented to the mind to have been which really never

was, will remain to be shown. And therefore how far the consciousness of

past actions is annexed to any individual agent, so that another cannot

possibly have it, will be hard for us to determine, til we know what

kind of action it is that cannot be done without a reflex act of

perception accompanying it, and how performed by thinking substances,

who cannot think without being conscious of it. But that which we call

the same consciousness, not being the same individual act, why one

intellectual substance may not have represented to it, as done

by itself, what IT never did, and was perhaps done by some other

agent--why, I say, such a representation may not possibly be without

reality of matter of fact, as well as several representations in dreams

are, which yet whilst dreaming we take for true--wil be difficult to

conclude from the nature of things. And that it never is so, will by us,

til we have clearer views of the nature of thinking substances, be

best resolved into the goodness of God; who, as far as the happiness or

misery of any of his sensible creatures is concerned in it, will not, by

a fatal error of theirs, transfer from one to another that consciousness

which draws reward or punishment with it. How far this may be an

argument against those who would place thinking in a system of fleeting

animal spirits, I leave to be considered. But yet, to return to the

question before us, it must be allowed, that, if the same consciousness

(which, as has been shown, is quite a different thing from the same

numerical figure or motion in body) can be transferred from one thinking

substance to another, it wil be possible that two thinking substances

may make but one person. For the same consciousness being preserved,

whether in the same or different substances, the personal identity is

preserved.

16. Whether, the same immaterial Substance remaining, there

can be two Persons.

As to the second part of the question, Whether the same immaterial

substance remaining, there may be two distinct persons; which question

seems to me to be built on this,--Whether the same immaterial being,

being conscious of the action of its past duration, may be wholly

stripped of all the consciousness of its past existence, and lose

it beyond the power of ever retrieving it again: and so as it were

beginning a new account from a new period, have a consciousness that

CANNOT reach beyond this new state. Al those who hold pre-existence are

evidently of this mind; since they allow the soul to have no remaining

consciousness of what it did in that pre-existent state, either wholly

separate from body, or informing any other body; and if they should not,

it is plain experience would be against them. So that personal identity,

reaching no further than consciousness reaches, a pre-existent spirit

not having continued so many ages in a state of silence, must needs

make different persons. Suppose a Christian Platonist or a Pythagorean

should, upon God's having ended all his works of creation the seventh

day, think his soul hath existed ever since; and should imagine it

has revolved in several human bodies; as I once met with one, who was

persuaded his had been the SOUL of Socrates (how reasonably I will

not dispute; this I know, that in the post he filled, which was no

inconsiderable one, he passed for a very rational man, and the press has

shown that he wanted not parts or learning;)--would any one say, that

he, being not conscious of any of Socrates's actions or thoughts, could

be the same PERSON with Socrates? Let any one reflect upon himself, and

conclude that he has in himself an immaterial spirit, which is that

which thinks in him, and, in the constant change of his body keeps him

the same: and is that which he cal s HIMSELF: let his also suppose it to

be the same soul that was in Nestor or Thersites, at the siege of Troy,

(for souls being, as far as we know anything of them, in their nature

indifferent to any parcel of matter, the supposition has no apparent

absurdity in it,) which it may have been, as wel as it is now the soul

of any other man: but he now having no consciousness of any of the

actions either of Nestor or Thersites, does or can he conceive himself

the same person with either of them? Can he be concerned in either of

their actions? attribute them to himself, or think them his own more

than the actions of any other men that ever existed? So that this

consciousness, not reaching to any of the actions of either of those

men, he is no more one SELF with either of them than of the soul of

immaterial spirit that now informs him had been created, and began to

exist, when it began to inform his present body; though it were never

so true, that the same SPIRIT that informed Nestor's or Thersites' body

were numerically the same that now informs his. For this would no more

make him the same person with Nestor, than if some of the particles of

smaller that were once a part of Nestor were now a part of this man

the same immaterial substance, without the same consciousness, no more

making the same person, by being united to any body, than the same

particle of matter, without consciousness, united to any body, makes

the same person. But let him once find himself conscious of any of the

actions of Nestor, he then finds himself the same person with Nestor.

17. The body, as well as the soul, goes to the making of a Man.

And thus may we be able, without any difficulty, to conceive the same

person at the resurrection, though in a body not exactly in make or

parts the same which he had here,--the same consciousness going along

with the soul that inhabits it. But yet the soul alone, in the change of

bodies, would scarce to any one but to him that makes the soul the

man, be enough to make the same man. For should the soul of a prince,

carrying with it the consciousness of the prince's past life, enter and

inform the body of a cobbler, as soon as deserted by his own soul, every

one sees he would be the same PERSON with the prince, accountable only

for the prince's actions: but who would say it was the same MAN? The

body too goes to the making the man, and would, I guess, to everybody

determine the man in this case, wherein the soul, with all its princely

thoughts about it, would not make another man: but he would be the same

cobbler to every one besides himself. I know that, in the ordinary way

of speaking, the same person, and the same man, stand for one and the

same thing. And indeed every one will always have a liberty to speak as

he pleases, and to apply what articulate sounds to what ideas he thinks

fit, and change them as often as he pleases. But yet, when we wil

inquire what makes the same SPIRIT, MAN, or PERSON, we must fix the

ideas of spirit, man, or person in our minds; and having resolved with

ourselves what we mean by them, it wil not be hard to determine, in

either of them, or the like, when it is the same, and when not.

18. Consciousness alone unites actions into the same Person.

But though the same immaterial substance or soul does not alone,

wherever it be, and in whatsoever state, make the same MAN; yet it is

plain, consciousness, as far as ever it can be extended--should it be to

ages past--unites existences and actions very remote in time into the

same PERSON, as well as it does the existences and actions of the

immediately preceding moment: so that whatever has the consciousness of

present and past actions, is the same person to whom they both belong.

Had I the same consciousness that I saw the ark and Noah's flood, as

that I saw an overflowing of the Thames last winter, or as that I write

now, I could no more doubt that I who write this now, that saw the

Thames overflowed last winter, and that viewed the flood at the general

deluge, was the same SELF,--place that self in what SUBSTANCE you

please--than that I who write this am the same MYSELF now whilst I write

(whether I consist of all the same substance material or immaterial, or

no) that I was yesterday. For as to this point of being the same self,

it matters not whether this present self be made up of the same or other

substances--I being as much concerned, and as justly accountable for

any action that was done a thousand years since, appropriated to me now

by this self-consciousness, as I am for what I did the last moment.

19. Self depends on Consciousness, not on Substance.

SELF is that conscious thinking thing,--whatever substance made up

of, (whether spiritual or material, simple or compounded, it matters

not)--which is sensible or conscious of pleasure and pain, capable of

happiness or misery, and so is concerned for itself, as far as that

consciousness extends. Thus every one finds that, whilst comprehended

under that consciousness, the little finger is as much a part of himself

as what is most so. Upon separation of this little finger, should this

consciousness go along with the little finger, and leave the rest of

the body, it is evident the little finger would be the person, the same

person; and self then would have nothing to do with the rest of the

body. As in this case it is the consciousness that goes along with the

substance, when one part is separate from another, which makes the same

person, and constitutes this inseparable self: so it is in reference to

substances remote in time. That with which the consciousness of this

present thinking thing CAN join itself, makes the same person, and is

one self with it, and with nothing else; and so attributes to itself,

and owns al the actions of that thing, as its own, as far as that

consciousness reaches, and no further; as every one who reflects will

perceive.

20. Persons, not Substances, the Objects of Reward and Punishment.

In this personal identity is founded al the right and justice of reward

and punishment; happiness and misery being that for which every one is

concerned for HIMSELF, and not mattering what becomes of any SUBSTANCE,

not joined to, or affected with that consciousness. For, as it is

evident in the instance I gave but now, if the consciousness went along

with the little finger when it was cut off, that would be the same self

which was concerned for the whole body yesterday, as making part of

itself, whose actions then it cannot but admit as its own now. Though,

if the same body should still live, and immediately from the separation

of the little finger have its own peculiar consciousness, whereof the

little finger knew nothing, it would not at all be concerned for it, as

a part of itself, or could own any of its actions, or have any of them

imputed to him.

21. Which shows wherein Personal identity consists.

This may show us wherein personal identity consists: not in the identity

of substance, but, as I have said, in the identity of consciousness,

wherein if Socrates and the present mayor of Queenborough agree, they

are the same person: if the same Socrates waking and sleeping do not

partake of the same consciousness, Socrates waking and sleeping is

not the same person. And to punish Socrates waking for what sleeping

Socrates thought, and waking Socrates was never conscious of, would be

no more of right, than to punish one twin for what his brother-twin did,

whereof he knew nothing, because their outsides were so like, that they

could not be distinguished; for such twins have been seen.

22. Absolute oblivion separates what is thus forgotten from the person,

but not from the man.

But yet possibly it will stil be objected,--Suppose I wholly lose the

memory of some parts of my life, beyond a possibility of retrieving

them, so that perhaps I shall never be conscious of them again; yet am

I not the same person that did those actions, had those thoughts that I

once was conscious of, though I have now forgot them? To which I answer,

that we must here take notice what the word _I_ is applied to; which, in

this case, is the MAN only. And the same man being presumed to be the

same person, I is easily here supposed to stand also for the same

person. But if it be possible for the same man to have distinct

incommunicable consciousness at different times, it is past doubt the

same man would at different times make different persons; which, we see,

is the sense of mankind in the solemnest declaration of their opinions,

human laws not punishing the mad man for the sober man's actions,

nor the sober man for what the mad man did,--thereby making them two

persons: which is somewhat explained by our way of speaking in English

when we say such an one is 'not himself,' or is 'beside himself'; in

which phrases it is insinuated, as if those who now, or at least first

used them, thought that self was changed; the selfsame person was no

longer in that man.

23. Difference between Identity of Man and of Person.

But yet it is hard to conceive that Socrates, the same individual man,

should be two persons. To help us a little in this, we must consider

what is meant by Socrates, or the same individual MAN.

First, it must be either the same individual, immaterial, thinking

substance; in short, the same numerical soul, and nothing else.

Secondly, or the same animal, without any regard to an immaterial soul.

Thirdly, or the same immaterial spirit united to the same animal.

Now, take which of these suppositions you please, it is impossible to

make personal identity to consist in anything but consciousness; or

reach any further than that does.

For, by the first of them, it must be alowed possible that a man born

of different women, and in distant times, may be the same man. A way of

speaking which, whoever admits, must allow it possible for the same man

to be two distinct persons, as any two that have lived in different ages

without the knowledge of one another's thoughts.

By the second and third, Socrates, in this life and after it, cannot be

the same man any way, but by the same consciousness; and so making

human identity to consist in the same thing wherein we place personal

identity, there will be difficulty to al ow the same man to be the same

person. But then they who place human identity in consciousness only,

and not in something else, must consider how they wil make the infant

Socrates the same man with Socrates after the resurrection. But

whatsoever to some men makes a man, and consequently the same individual

man, wherein perhaps few are agreed, personal identity can by us be

placed in nothing but consciousness, (which is that alone which makes

what we call SELF,) without involving us in great absurdities.

24.

But is not a man drunk and sober the same person? why else is he

punished for the fact he commits when drunk, though he be never

afterwards conscious of it? Just as much the same person as a man that

walks, and does other things in his sleep, is the same person, and is

answerable for any mischief he shall do in it. Human laws punish both,

with a justice suitable to THEIR way of knowledge;--because, in these

cases, they cannot distinguish certainly what is real, what counterfeit:

and so the ignorance in drunkenness or sleep is not admitted as a plea.

But in the Great Day, wherein the secrets of all hearts shall be laid

open, it may be reasonable to think, no one shall be made to answer for

what he knows nothing of; but shall receive his doom, his conscience

accusing or excusing him.

25. Consciousness alone unites remote existences into one Person.

Nothing but consciousness can unite remote existences into the same

person: the identity of substance wil not do it; for whatever substance

there is, however framed, without consciousness there is no person:

and a carcass may be a person, as well as any sort of substance be so,

without consciousness.

Could we suppose two distinct incommunicable consciousnesses acting the

same body, the one constantly by day, the other by night; and, on the

other side, the same consciousness, acting by intervals, two distinct

bodies: I ask, in the first case, whether the day and the night--man

would not be two as distinct persons as Socrates and Plato? And whether,

in the second case, there would not be one person in two distinct

bodies, as much as one man is the same in two distinct clothings? Nor

is it at all material to say, that this same, and this distinct

consciousness, in the cases above mentioned, is owing to the same and

distinct immaterial substances, bringing it with them to those bodies;

which, whether true or no, alters not the case: since it is evident the

personal identity would equally be determined by the consciousness,

whether that consciousness were annexed to some individual immaterial

substance or no. For, granting that the thinking substance in man must

be necessarily supposed immaterial, it is evident that immaterial

thinking thing may sometimes part with its past consciousness, and be

restored to it again: as appears in the forgetfulness men often have of

their past actions; and the mind many times recovers the memory of a

past consciousness, which it had lost for twenty years together.

Make these intervals of memory and forgetfulness to take their turns

regularly by day and night, and you have two persons with the same

immaterial spirit, as much as in the former instance two persons with

the same body. So that self is not determined by identity or diversity

of substance, which it cannot be sure of, but only by identity of

consciousness.

26. Not the substance with which the consciousness may be united.

Indeed it may conceive the substance whereof it is now made up to have

existed formerly, united in the same conscious being: but, consciousness

removed, that substance is no more itself, or makes no more a part of

it, than any other substance; as is evident in the instance we have

already given of a limb cut off, of whose heat, or cold, or other

affections, having no longer any consciousness, it is no more of a man's

self than any other matter of the universe. In like manner it will be

in reference to any immaterial substance, which is void of that

consciousness whereby I am myself to myself: so that I cannot upon

recollection join with that present consciousness whereby I am now

myself, it is, in that part of its existence, no more MYSELF than any

other immaterial being. For, whatsoever any substance has thought or

done, which I cannot recollect, and by my consciousness make my own

thought and action, it wil no more belong to me, whether a part of me

thought or did it, than if it had been thought or done by any other

immaterial being anywhere existing.

27. Consciousness unites substances, material or spiritual, with the

same personality.

I agree, the more probable opinion is, that this consciousness is

annexed to, and the affection of, one individual immaterial substance.

But let men, according to their diverse hypotheses, resolve of that as

they please. This every intelligent being, sensible of happiness or

misery, must grant--that there is something that is HIMSELF, that he is

concerned for, and would have happy; that this self has existed in a

continued duration more than one instant, and therefore it is possible

may exist, as it has done, months and years to come, without any certain

bounds to be set to its duration; and may be the same self, by the

same consciousness continued on for the future. And thus, by this

consciousness he finds himself to be the same self which did such and

such an action some years since, by which he comes to be happy or

miserable now. In al which account of self, the same numerical

SUBSTANCE is not considered a making the same self; but the same

continued CONSCIOUSNESS, in which several substances may have been

united, and again separated from it, which, whilst they continued in a

vital union with that wherein this consciousness then resided, made a

part of that same self. Thus any part of our bodies, vitally united

to that which is conscious in us, makes a part of ourselves: but

upon separation from the vital union by which that consciousness is

communicated, that which a moment since was part of ourselves, is now no

more so than a part of another man's self is a part of me: and it is

not impossible but in a little time may become a real part of another

person. And so we have the same numerical substance become a part of two

different persons; and the same person preserved under the change of

various substances. Could we suppose any spirit wholly stripped of all

its memory of consciousness of past actions, as we find our minds always

are of a great part of ours, and sometimes of them al ; the union or

separation of such a spiritual substance would make no variation of

personal identity, any more than that of any particle of matter does.

Any substance vitally united to the present thinking being is a part

of that very same self which now is; anything united to it by a

consciousness of former actions, makes also a part of the same self,

which is the same both then and now.

28. Person a forensic Term.

PERSON, as I take it, is the name for this self. Wherever a man finds

what he cal s himself, there, I think, another may say is the same

person. It is a forensic term, appropriating actions and their merit;

and so belongs only to intel igent agents, capable of a law, and

happiness, and misery. This personality extends itself beyond present

existence to what is past, only by consciousness,--whereby it becomes

concerned and accountable; owns and imputes to itself past actions, just

upon the same ground and for the same reason as it does the present. All

which is founded in a concern for happiness, the unavoidable concomitant

of consciousness; that which is conscious of pleasure and pain, desiring

that that self that is conscious should be happy. And therefore whatever

past actions it cannot reconcile or APPROPRIATE to that present self by

consciousness, it can be no more concerned in than if they had never

been done: and to receive pleasure or pain, i.e. reward or punishment,

on the account of any such action, is all one as to be made happy or

miserable in its first being, without any demerit at al . For, supposing

a MAN punished now for what he had done in another life, whereof he

could be made to have no consciousness at al , what difference is there

between that punishment and being CREATED miserable? And therefore,

conformable to this, the apostle tells us, that, at the great day, when

every one shall 'receive according to his doings, the secrets of al

hearts shall be laid open.' The sentence shall be justified by the

consciousness al persons shall have, that THEY THEMSELVES, in what

bodies soever they appear, or what substances soever that consciousness

adheres to, are the SAME that committed those actions, and deserve that

punishment for them.

29. Suppositions that look strange are pardonable in our ignorance.

I
