_Phil._ The same that I should myself, to wit, that it doth exist out of

his mind. But then to a Christian it cannot surely be shocking to say, the

real tree, existing without his mind, is truly known and comprehended by

(that is _exists in_) the infinite mind of God. Probably he may not at

first glance be aware of the direct and immediate proof there is of this;

inasmuch as the very being of a tree, or any other sensible thing, implies

a mind wherein it is. But the point itself he cannot deny. The question

between the Materialists and me is not, whether things have a _real_

existence out of the mind of this or that person(872), but, whether they

have an _absolute_ existence, distinct from being perceived by God, and

exterior to _all_ minds(873). This indeed some heathens and philosophers

have affirmed, but whoever entertains notions of the Deity suitable to the

Holy Scriptures will be of another opinion.

_Hyl._ But, according to your notions, what difference is there between

real things, and chimeras formed by the imagination, or the visions of a

dream—since they are all equally in the mind(874)?

_Phil._ The ideas formed by the imagination are faint and indistinct; they

have, besides, an entire dependence on the will. But the ideas perceived

by sense, that is, real things, are more vivid and clear; and, being

imprinted on the mind by a spirit distinct from us, have not the like

dependence on our will. There is therefore no danger of confounding these

with the foregoing: and there is as little of confounding them with the

visions of a dream, which are dim, irregular, and confused. And, though

they should happen to be never so lively and natural, yet, by their not

being connected, and of apiece with the preceding and subsequent

transactions of our lives, they might easily be distinguished from

realities. In short, by whatever method you distinguish _things_ from

_chimeras_ on your scheme, the same, it is evident, will hold also upon

mine. For, it must be, I presume, by some perceived difference; and I am

not for depriving you of any one thing that you perceive.

_Hyl._ But still, Philonous, you hold, there is nothing in the world but

spirits and ideas. And this, you must needs acknowledge, sounds very

oddly.

_Phil._ I own the word _idea_, not being commonly used for _thing_, sounds

something out of the way. My reason for using it was, because a necessary

relation to the mind is understood to be implied by that term; and it is

now commonly used by philosophers to denote the immediate objects of the

understanding. But, however oddly the proposition may sound in words, yet

it includes nothing so very strange or shocking in its sense; which in

effect amounts to no more than this, to wit, that there are only things

perceiving, and things perceived; or that every unthinking being is

necessarily, and from the very nature of its existence, perceived by some

mind; if not by a finite created mind, yet certainly by the infinite mind

of God, in whom ’we live, and move, and have our being.’ Is this as

strange as to say, the sensible qualities are not on the objects: or that

we cannot be sure of the existence of things, or know anything of their

real natures—though we both see and feel them, and perceive them by all

our senses?

_Hyl._ And, in consequence of this, must we not think there are no such

things as physical or corporeal causes; but that a Spirit is the immediate

cause of all the phenomena in nature? Can there be anything more

extravagant than this?

_Phil._ Yes, it is infinitely more extravagant to say—a thing which is

inert operates on the mind, and which is unperceiving is the cause of our

perceptions, [(875)without any regard either to consistency, or the old

known axiom, _Nothing can give to another that which it hath not itself_].

Besides, that which to you, I know not for what reason, seems so

extravagant is no more than the Holy Scriptures assert in a hundred

places. In them God is represented as the sole and immediate Author of all

those effects which some heathens and philosophers are wont to ascribe to

Nature, Matter, Fate, or the like unthinking principle. This is so much

the constant language of Scripture that it were needless to confirm it by

citations.

_Hyl._ You are not aware, Philonous, that, in making God the immediate

Author of all the motions in nature, you make Him the Author of murder,

sacrilege, adultery, and the like heinous sins.

_Phil._ In answer to that, I observe, first, that the imputation of guilt

is the same, whether a person commits an action with or without an

instrument. In case therefore you suppose God to act by the mediation of

an instrument, or occasion, called _Matter_, you as truly make Him the

author of sin as I, who think Him the immediate agent in all those

operations vulgarly ascribed to Nature. I farther observe that sin or

moral turpitude doth not consist in the outward physical action or motion,

but in the internal deviation of the will from the laws of reason and

religion. This is plain, in that the killing an enemy in a battle, or

putting a criminal legally to death, is not thought sinful; though the

outward act be the very same with that in the case of murder. Since,

therefore, sin doth not consist in the physical action, the making God an

immediate cause of all such actions is not making Him the Author of sin.

Lastly, I have nowhere said that God is the only agent who produces all

the motions in bodies. It is true I have denied there are any other agents

besides spirits; but this is very consistent with allowing to thinking

rational beings, in the production of motions, the use of limited powers,

ultimately indeed derived from God, but immediately under the direction of

their own wills, which is sufficient to entitle them to all the guilt of

their actions(876).

_Hyl._ But the denying Matter, Philonous, or corporeal Substance; there is

the point. You can never persuade me that this is not repugnant to the

universal sense of mankind. Were our dispute to be determined by most

voices, I am confident you would give up the point, without gathering the

votes.

_Phil._ I wish both our opinions were fairly stated and submitted to the

judgment of men who had plain common sense, without the prejudices of a

learned education. Let me be represented as one who trusts his senses, who

thinks he knows the things he sees and feels, and entertains no doubts of

their existence; and you fairly set forth with all your doubts, your

paradoxes, and your scepticism about you, and I shall willingly acquiesce

in the determination of any indifferent person. That there is no substance

wherein ideas can exist beside spirit is to me evident. And that the

objects immediately perceived are ideas, is on all hands agreed(877). And

that sensible qualities are objects immediately perceived no one can deny.

It is therefore evident there can be no _substratum_ of those qualities

but spirit; _in_ which they exist, not by way of mode or property, but as

a thing perceived in that which perceives it(878). I deny therefore that

there is any unthinking _substratum_ of the objects of sense, and _in that

acceptation_ that there is any material substance. But if by _material

substance_ is meant only _sensible body_—that which is seen and felt (and

the unphilosophical part of the world, I dare say, mean no more)—then I am

more certain of matter’s existence than you or any other philosopher

pretend to be. If there be anything which makes the generality of mankind

averse from the notions I espouse: it is a misapprehension that I deny the

reality of sensible things. But, as it is you who are guilty of that, and

not I, it follows that in truth their aversion is against your notions and

not mine. I do therefore assert that I am as certain as of my own being,

that there are bodies or corporeal substances (meaning the things I

perceive by my senses); and that, granting this, the bulk of mankind will

take no thought about, nor think themselves at all concerned in the fate

of those unknown natures, and philosophical quiddities, which some men are

so fond of.

_Hyl._ What say you to this? Since, according to you, men judge of the

reality of things by their senses, how can a man be mistaken in thinking

the moon a plain lucid surface, about a foot in diameter; or a square

tower, seen at a distance, round; or an oar, with one end in the water,

crooked?

_Phil._ He is not mistaken with regard to the ideas he actually perceives,

but in the inferences he makes from his present perceptions. Thus, in the

case of the oar, what he immediately perceives by sight is certainly

crooked; and so far he is in the right. But if he thence conclude that

upon taking the oar out of the water he shall perceive the same

crookedness; or that it would affect his touch as crooked things are wont

to do: in that he is mistaken. In like manner, if he shall conclude from

what he perceives in one station, that, in case he advances towards the

moon or tower, he should still be affected with the like ideas, he is

mistaken. But his mistake lies not in what he perceives immediately, and

at present, (it being a manifest contradiction to suppose he should err in

respect of that) but in the wrong judgment he makes concerning the ideas

he apprehends to be connected with those immediately perceived: or,

concerning the ideas that, from what he perceives at present, he imagines

would be perceived in other circumstances. The case is the same with

regard to the Copernican system. We do not here perceive any motion of the

earth: but it were erroneous thence to conclude, that, in case we were

placed at as great a distance from that as we are now from the other

planets, we should not then perceive its motion(879).

_Hyl._ I understand you; and must needs own you say things plausible

enough. But, give me leave to put you in mind of one thing. Pray,

Philonous, were you not formerly as positive that Matter existed, as you

are now that it does not?

_Phil._ I was. But here lies the difference. Before, my positiveness was

founded, without examination, upon prejudice; but now, after inquiry, upon

evidence.

_Hyl._ After all, it seems our dispute is rather about words than things.

We agree in the thing, but differ in the name. That we are affected with

ideas _from without_ is evident; and it is no less evident that there must

be (I will not say archetypes, but) Powers without the mind(880),

corresponding to those ideas. And, as these Powers cannot subsist by

themselves, there is some subject of them necessarily to be admitted;

which I call _Matter_, and you call _Spirit_. This is all the difference.

_Phil._ Pray, Hylas, is that powerful Being, or subject of powers,

extended?

_Hyl._ It hath not extension; but it hath the power to raise in you the

idea of extension,

_Phil._ It is therefore itself unextended?

_Hyl._ I grant it.

_Phil._ Is it not also active?

_Hyl._ Without doubt. Otherwise, how could we attribute powers to it?

_Phil._ Now let me ask you two questions: _First_, Whether it be agreeable

to the usage either of philosophers or others to give the name _Matter_ to

an unextended active being? And, _Secondly_, Whether it be not

ridiculously absurd to misapply names contrary to the common use of

language?

_Hyl._ Well then, let it not be called Matter, since you will have it so,

but some _Third Nature_ distinct from Matter and Spirit. For what reason

is there why you should call it Spirit? Does not the notion of spirit

imply that it is thinking, as well as active and unextended?

_Phil._ My reason is this: because I have a mind to have some notion of

meaning in what I say: but I have no notion of any action distinct from

volition, neither can I conceive volition to be anywhere but in a spirit:

therefore, when I speak of an active being, I am obliged to mean a Spirit.

Beside, what can be plainer than that a thing which hath no ideas in

itself cannot impart them to me; and, if it hath ideas, surely it must be

a Spirit. To make you comprehend the point still more clearly if it be

possible. I assert as well as you that, since we are affected from

without, we must allow Powers to be without, in a Being distinct from

ourselves. So far we are agreed. But then we differ as to the kind of this

powerful Being(881). I will have it to be Spirit, you Matter, or I know

not what (I may add too, you know not what) Third Nature. Thus, I prove it

to be Spirit. From the effects I see produced, I conclude there are

actions; and, because actions, volitions; and, because there are

volitions, there must be a _will_. Again, the things I perceive must have

an existence, they or their archetypes, out of _my_ mind: but, being

ideas, neither they nor their archetypes can exist otherwise than in an

understanding; there is therefore an _understanding_. But will and

understanding constitute in the strictest sense a mind or spirit. The

powerful cause, therefore, of my ideas is in strict propriety of speech a

_Spirit_.

_Hyl._ And now I warrant you think you have made the point very clear,

little suspecting that what you advance leads directly to a contradiction.

Is it not an absurdity to imagine any imperfection in God?

_Phil._ Without a doubt.

_Hyl._ To suffer pain is an imperfection?

_Phil._ It is.

_Hyl._ Are we not sometimes affected with pain and uneasiness by some

other Being?

_Phil._ We are.

_Hyl._ And have you not said that Being is a Spirit, and is not that

Spirit God?

_Phil._ I grant it.

_Hyl._ But you have asserted that whatever ideas we perceive from without

are in the mind which affects us. The ideas, therefore, of pain and

uneasiness are in God; or, in other words, God suffers pain: that is to

say, there is an imperfection in the Divine nature: which, you

acknowledged, was absurd. So you are caught in a plain contradiction(882).

_Phil._ That God knows or understands all things, and that He knows, among

other things, what pain is, even every sort of painful sensation, and what

it is for His creatures to suffer pain, I make no question. But, that God,

though He knows and sometimes causes painful sensations in us, can Himself

suffer pain, I positively deny. We, who are limited and dependent spirits,

are liable to impressions of sense, the effects of an external Agent,

which, being produced against our wills, are sometimes painful and uneasy.

But God, whom no external being can affect, who perceives nothing by sense

as we do; whose will is absolute and independent, causing all things, and

liable to be thwarted or resisted by nothing: it is evident, such a Being

as this can suffer nothing, nor be affected with any painful sensation, or

indeed any sensation at all. We are chained to a body: that is to say, our

perceptions are connected with corporeal motions. By the law of our

nature, we are affected upon every alteration in the nervous parts of our

sensible body; which sensible body, rightly considered, is nothing but a

complexion of such qualities or ideas as have no existence distinct from

being perceived by a mind. So that this connexion of sensations with

corporeal motions means no more than a correspondence in the order of

nature, between two sets of ideas, or things immediately perceivable. But

God is a Pure Spirit, disengaged from all such sympathy, or natural ties.

No corporeal motions are attended with the sensations of pain or pleasure

in His mind. To know everything knowable, is certainly a perfection; but

to endure, or suffer, or feel anything by sense, is an imperfection. The

former, I say, agrees to God, but not the latter. God knows, or hath

ideas; but His ideas are not conveyed to Him by sense, as ours are. Your

not distinguishing, where there is so manifest a difference, makes you

fancy you see an absurdity where there is none.

_Hyl._ But, all this while you have not considered that the quantity of

Matter has been demonstrated to be proportioned to the gravity of

bodies(883). And what can withstand demonstration?

_Phil._ Let me see how you demonstrate that point.

_Hyl._ I lay it down for a principle, that the moments or quantities of

motion in bodies are in a direct compounded reason of the velocities and

quantities of Matter contained in them. Hence, where the velocities are

equal, it follows the moments are directly as the quantity of Matter in

each. But it is found by experience that all bodies (bating the small

inequalities, arising from the resistance of the air) descend with an

equal velocity; the motion therefore of descending bodies, and

consequently their gravity, which is the cause or principle of that

motion, is proportional to the quantity of Matter; which was to be

demonstrated.

_Phil._ You lay it down as a self-evident principle that the quantity of

motion in any body is proportional to the velocity and _Matter_ taken

together; and this is made use of to prove a proposition from whence the

existence of _Matter_ is inferred. Pray is not this arguing in a circle?

_Hyl._ In the premise I only mean that the motion is proportional to the

velocity, jointly with the extension and solidity.

_Phil._ But, allowing this to be true, yet it will not thence follow that

gravity is proportional to _Matter_, in your philosophic sense of the

word; except you take it for granted that unknown _substratum_, or

whatever else you call it, is proportional to those sensible qualities;

which to suppose is plainly begging the question. That there is magnitude

and solidity, or resistance, perceived by sense, I readily grant; as

likewise, that gravity may be proportional to those qualities I will not

dispute. But that either these qualities as perceived by us, or the powers

producing them, do exist in a _material substratum_; this is what I deny,

and you indeed affirm, but, notwithstanding your demonstration, have not

yet proved.

_Hyl._ I shall insist no longer on that point. Do you think, however, you

shall persuade me the natural philosophers have been dreaming all this

while? Pray what becomes of all their hypotheses and explications of the

phenomena, which suppose the existence of Matter(884)?

_Phil._ What mean you, Hylas, by the _phenomena_?

_Hyl._ I mean the appearances which I perceive by my senses.

_Phil._ And the appearances perceived by sense, are they not ideas?

_Hyl._ I have told you so a hundred times.

_Phil._ Therefore, to explain the phenomena is, to shew how we come to be

affected with ideas, in that manner and(885) order wherein they are

imprinted on our senses. Is it not?

_Hyl._ It is.

_Phil._ Now, if you can prove that any philosopher has explained the

production of any one idea in our minds by the help of _Matter_(886), I

shall for ever acquiesce, and look on all that hath been said against it

as nothing; but, if you cannot, it is vain to urge the explication of

phenomena. That a Being endowed with knowledge and will should produce or

exhibit ideas is easily understood. But that a Being which is utterly

destitute of these faculties should be able to produce ideas, or in any

sort to affect an intelligence, this I can never understand. This I say,

though we had some positive conception of Matter, though we knew its

qualities, and could comprehend its existence, would yet be so far from

explaining things, that it is itself the most inexplicable thing in the

world. And yet, for all this, it will not follow that philosophers have

been doing nothing; for, by observing and reasoning upon the connexion of

ideas(887), they discover the laws and methods of nature, which is a part

of knowledge both useful and entertaining.

_Hyl._ After all, can it be supposed God would deceive all mankind? Do you

imagine He would have induced the whole world to believe the being of

Matter, if there was no such thing?

_Phil._ That every epidemical opinion, arising from prejudice, or passion,

or thoughtlessness, may be imputed to God, as the Author of it, I believe

you will not affirm. Whatsoever opinion we father on Him, it must be

either because He has discovered it to us by supernatural revelation; or

because it is so evident to our natural faculties, which were framed and

given us by God, that it is impossible we should withhold our assent from

it. But where is the revelation? or where is the evidence that extorts the

belief of Matter? Nay, how does it appear, that Matter, _taken for

something distinct from what we perceive by our senses_, is thought to

exist by all mankind; or, indeed, by any except a few philosophers, who do

not know what they would be at? Your question supposes these points are

clear; and, when you have cleared them, I shall think myself obliged to

give you another answer. In the meantime, let it suffice that I tell you,

I do not suppose God has deceived mankind at all.

_Hyl._ But the novelty, Philonous, the novelty! There lies the danger. New

notions should always be discountenanced; they unsettle men’s minds, and

nobody knows where they will end.

_Phil._ Why the rejecting a notion that has no foundation, either in

sense, or in reason, or in Divine authority, should be thought to unsettle

the belief of such opinions as are grounded on all or any of these, I

cannot imagine. That innovations in government and religion are dangerous,

and ought to be discountenanced, I freely own. But is there the like

reason why they should be discouraged in philosophy? The making anything

known which was unknown before is an innovation in knowledge: and, if all

such innovations had been forbidden, men would have made a notable

progress in the arts and sciences. But it is none of my business to plead

for novelties and paradoxes. That the qualities we perceive are not on the

objects: that we must not believe our senses: that we know nothing of the

real nature of things, and can never be assured even of their existence:

that real colours and sounds are nothing but certain unknown figures and

motions: that motions are in themselves neither swift nor slow: that there

are in bodies absolute extensions, without any particular magnitude or

figure: that a thing stupid, thoughtless, and inactive, operates on a

spirit: that the least particle of a body contains innumerable extended

parts:—these are the novelties, these are the strange notions which shock

the genuine uncorrupted judgment of all mankind; and being once admitted,

embarrass the mind with endless doubts and difficulties. And it is against

these and the like innovations I endeavour to vindicate Common Sense. It

is true, in doing this, I may perhaps be obliged to use some _ambages_,

and ways of speech not common. But, if my notions are once thoroughly

understood, that which is most singular in them will, in effect, be found

to amount to no more than this:—that it is absolutely impossible, and a

plain contradiction, to suppose any unthinking Being should exist without

being perceived by a Mind. And, if this notion be singular, it is a shame

it should be so, at this time of day, and in a Christian country.

_Hyl._ As for the difficulties other opinions may be liable to, those are

out of the question. It is your business to defend your own opinion. Can

anything be plainer than that you are for changing all things into ideas?

You, I say, who are not ashamed to charge me with _scepticism_. This is so

plain, there is no denying it.

_Phil._ You mistake me. I am not for changing things into ideas, but

rather ideas into things(888); since those immediate objects of

perception, which, according to you, are only appearances of things, I

take to be the real things themselves(889).

_Hyl._ Things! You may pretend what you please; but it is certain you

leave us nothing but the empty forms of things, the outside only which

strikes the senses.

_Phil._ What you call the empty forms and outside of things seem to me the

very things themselves. Nor are they empty or incomplete, otherwise than

upon your supposition—that Matter(890) is an essential part of all

corporeal things. We both, therefore, agree in this, that we perceive only

sensible forms: but herein we differ—you will have them to be empty

appearances, I real beings. In short, you do not trust your senses, I do.

_Hyl._ You say you believe your senses; and seem to applaud yourself that

in this you agree with the vulgar. According to you, therefore, the true

nature of a thing is discovered by the senses. If so, whence comes that

disagreement? Why is not the same figure, and other sensible qualities,

perceived all manner of ways? and why should we use a microscope the

better to discover the true nature of a body, if it were discoverable to

the naked eye?
