15. In short, let any one consider those arguments which are thought

manifestly to prove that colours and tastes exist only in the mind, and he

shall find they may with equal force be brought to prove the same thing of

extension, figure, and motion. Though it must be confessed this method of

arguing does not so much prove that there is no extension or colour in an

outward object, as that we do not know by sense which is the true

extension or colour of the object. But the arguments foregoing(553)

plainly shew it to be impossible that any colour or extension at all, or

other sensible quality whatsoever, should exist in an unthinking subject

without the mind, or in truth that there should be any such thing as an

outward object(554).

16. But let us examine a little the received opinion. It is said extension

is a _mode_ or _accident_ of Matter, and that Matter is the _substratum_

that supports it. Now I desire that you would explain to me what is meant

by Matter’s _supporting_ extension. Say you, I have no idea of Matter; and

therefore cannot explain it. I answer, though you have no positive, yet,

if you have any meaning at all, you must at least have a relative idea of

Matter; though you know not what it is, yet you must be supposed to know

what relation it bears to accidents, and what is meant by its supporting

them. It is evident _support_ cannot here be taken in its usual or literal

sense, as when we say that pillars support a building. In what sense

therefore must it be taken? [(555) For my part, I am not able to discover

any sense at all that can be applicable to it.]

17. If we inquire into what the most accurate philosophers declare

themselves to mean by _material substance_, we shall find them acknowledge

they have no other meaning annexed to those sounds but the idea of Being

in general, together with the relative notion of its supporting accidents.

The general idea of Being appeareth to me the most abstract and

incomprehensible of all other; and as for its supporting accidents, this,

as we have just now observed, cannot be understood in the common sense of

those words: it must therefore be taken in some other sense, but what that

is they do not explain. So that when I consider the two parts or branches

which make the signification of the words _material substance_, I am

convinced there is no distinct meaning annexed to them. But why should we

trouble ourselves any farther, in discussing this material _substratum_ or

support of figure and motion and other sensible qualities? Does it not

suppose they have an existence without the mind? And is not this a direct

repugnancy, and altogether inconceivable?

18. But, though it were possible that solid, figured, moveable substances

may exist without the mind, corresponding to the ideas we have of bodies,

yet how is it possible for us to know this? Either we must know it by

Sense or by Reason(556). As for our senses, by them we have the knowledge

only of our sensations, ideas, or those things that are immediately

perceived by sense, call them what you will: but they do not inform us

that things exist without the mind, or unperceived, like to those which

are perceived. This the materialists themselves acknowledge.—It remains

therefore that if we have any knowledge at all of external things, it must

be by reason inferring their existence from what is immediately perceived

by sense. But ((557)I do not see) what reason can induce us to believe the

existence of bodies without the mind, from what we perceive, since the

very patrons of Matter themselves do not pretend there is any necessary

connexion betwixt them and our ideas? I say it is granted on all hands

(and what happens in dreams, frensies, and the like, puts it beyond

dispute) that it is possible we might be affected with all the ideas we

have now, though no bodies existed without resembling them(558). Hence it

is evident the supposition of external bodies(559) is not necessary for

the producing our ideas; since it is granted they are produced sometimes,

and might possibly be produced always, in the same order we see them in at

present, without their concurrence.

19. But, though we might possibly have all our sensations without them,

yet perhaps it may be thought easier to conceive and explain the manner of

their production, by supposing external bodies in their likeness rather

than otherwise; and so it might be at least probable there are such things

as bodies that excite their ideas in our minds. But neither can this be

said. For, though we give the materialists their external bodies, they by

their own confession are never the nearer knowing how our ideas are

produced; since they own themselves unable to comprehend in what manner

body can act upon spirit, or how it is possible it should imprint any idea

in the mind(560). Hence it is evident the production of ideas or

sensations in our minds(561), can be no reason why we should suppose

Matter or corporeal substances(562); since that is acknowledged to remain

equally inexplicable with or without this supposition. If therefore it

were possible for bodies to exist without the mind, yet to hold they do so

must needs be a very precarious opinion; since it is to suppose, without

any reason at all, that God has created innumerable beings that are

entirely useless, and serve to no manner of purpose.

20. In short, if there were external bodies(563), it is impossible we

should ever come to know it; and if there were not, we might have the very

same reasons to think there were that we have now. Suppose—what no one can

deny possible—an intelligence, without the help of external bodies, to be

affected with the same train of sensations or ideas that you are,

imprinted in the same order and with like vividness in his mind. I ask

whether that intelligence hath not all the reason to believe the existence

of Corporeal Substances, represented by his ideas, and exciting them in

his mind, that you can possibly have for believing the same thing? Of this

there can be no question. Which one consideration were enough to make any

reasonable person suspect the strength of whatever arguments he may think

himself to have, for the existence of bodies without the mind.

21. Were it necessary to add any farther proof against the existence of

Matter(564), after what has been said, I could instance several of those

errors and difficulties (not to mention impieties) which have sprung from

that tenet. It has occasioned numberless controversies and disputes in

philosophy, and not a few of far greater moment in religion. But I shall

not enter into the detail of them in this place, as well because I think

arguments _a posteriori_ are unnecessary for confirming what has been, if

I mistake not, sufficiently demonstrated _a priori_, as because I shall

hereafter find occasion to speak somewhat of them.

‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐

22. I am afraid I have given cause to think I am needlessly prolix in

handling this subject. For, to what purpose is it to dilate on that which

may be demonstrated with the utmost evidence in a line or two, to any one

that is capable of the least reflexion? It is but looking into your own

thoughts, and so trying whether you can conceive it possible for a sound,

or figure, or motion, or colour to exist without the mind or unperceived.

This easy trial(565) may perhaps make you see that what you contend for is

a downright contradiction. Insomuch that I am content to put the whole

upon this issue:—If you can but conceive it possible for one extended

moveable substance, or in general for any one idea, or anything like an

idea, to exist otherwise than in a mind perceiving it(566), I shall

readily give up the cause. And, as for all that compages of external

bodies you contend for, I shall grant you its existence, though you cannot

either give me any reason why you believe it exists, or assign any use to

it when it is supposed to exist. I say, the bare possibility of your

opinions being true shall pass for an argument that it is so.

23. But, say you, surely there is nothing easier than for me to imagine

trees, for instance, in a park, or books existing in a closet, and nobody

by to perceive them. I answer, you may so, there is no difficulty in it.

But what is all this, I beseech you, more than framing in your mind

certain ideas which you call _books_ and _trees_, and at the same time

omitting to frame the idea of any one that may perceive them? But do not

you yourself perceive or think of them all the while? This therefore is

nothing to the purpose: it only shews you have the power of imagining, or

forming ideas in your mind; but it does not shew that you can conceive it

possible the objects of your thought may exist without the mind(567). To

make out this, it is necessary that you conceive them existing unconceived

or unthought of; which is a manifest repugnancy. When we do our utmost to

conceive the existence of external bodies(568), we are all the while only

contemplating our own ideas. But the mind, taking no notice of itself, is

deluded to think it can and does conceive bodies existing unthought of, or

without the mind, though at the same time they are apprehended by, or

exist in, itself. A little attention will discover to any one the truth

and evidence of what is here said, and make it unnecessary to insist on

any other proofs against the existence of _material substance_.

24. [(569)Could men but forbear to amuse themselves with words, we should,

I believe, soon come to an agreement in this point.] It is very obvious,

upon the least inquiry into our own thoughts, to know whether it be

possible for us to understand what is meant by the _absolute existence of

sensible objects in themselves_, or _without the mind_(570). To me it is

evident those words mark out either a direct contradiction, or else

nothing at all. And to convince others of this, I know no readier or

fairer way than to entreat they would calmly attend to their own thoughts;

and if by this attention the emptiness or repugnancy of those expressions

does appear, surely nothing more is requisite for their conviction. It is

on this therefore that I insist, to wit, that the _absolute existence of

unthinking things_ are words without a meaning, or which include a

contradiction. This is what I repeat and inculcate, and earnestly

recommend to the attentive thoughts of the reader.

‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐

25. All our ideas, sensations, notions(571), or the things which we

perceive, by whatsoever names they may be distinguished, are visibly

inactive: there is nothing of power or agency included in them. So that

one idea or object of thought cannot produce or make any alteration in

another(572). To be satisfied of the truth of this, there is nothing else

requisite but a bare observation of our ideas. For, since they and every

part of them exist only in the mind, it follows that there is nothing in

them but what is perceived; but whoever shall attend to his ideas, whether

of sense or reflexion, will not perceive in them any power or activity;

there is, therefore, no such thing contained in them. A little attention

will discover to us that the very being of an idea implies passiveness and

inertness in it; insomuch that it is impossible for an idea to do

anything, or, strictly speaking, to be the cause of anything: neither can

it be the resemblance or pattern of any active being, as is evident from

sect. 8. Whence it plainly follows that extension, figure, and motion

cannot be the cause of our sensations. To say, therefore, that these are

the effects of powers resulting from the configuration, number, motion,

and size of corpuscles(573), must certainly be false.

26. We perceive a continual succession of ideas; some are anew excited,

others are changed or totally disappear. There is therefore _some_ cause

of these ideas, whereon they depend, and which produces and changes

them(574). That this cause cannot be any quality or idea or combination of

_ideas_, is clear from the preceding section. It must therefore be a

_substance_; but it has been shewn that there is no corporeal or material

substance: it remains therefore that the cause of ideas is an incorporeal

active substance or Spirit(575).

27. A Spirit is one simple, undivided active being—as it perceives ideas

it is called the _understanding_, and as it produces or otherwise operates

about them it is called the _will_. Hence there can be no _idea_ formed of

a soul or spirit; for all ideas whatever, being passive and inert (vid.

sect. 25), they cannot represent unto us, by way of image or likeness,

that which acts. A little attention will make it plain to any one, that to

have an idea which shall be _like_ that active Principle of motion and

change of ideas is absolutely impossible. Such is the nature of Spirit, or

that which acts, that it cannot be of itself perceived, but only by the

effects which it produceth(576). If any man shall doubt of the truth of

what is here delivered, let him but reflect and try if he can frame the

idea of any power or active being; and whether he has ideas of two

principal powers, marked by the names _will_ and _understanding_, distinct

from each other, as well as from a third idea of Substance or Being in

general, with a relative notion of its supporting or being the subject of

the aforesaid powers—which is signified by the name _soul_ or _spirit_.

This is what some hold; but, so far as I can see, the words _will_,

[(577)_understanding_, _mind_,] _soul_, _spirit_, do not stand for

different ideas, or, in truth, for any idea at all, but for something

which is very different from ideas, and which, being an agent, cannot be

like unto, or represented by, any idea whatsoever. [(578)Though it must be

owned at the same time that we have some _notion_ of soul, spirit, and the

operations of the mind, such as willing, loving, hating—inasmuch as we

know or understand the meaning of these words.]

28. I find I can excite ideas(579) in my mind at pleasure, and vary and

shift the scene as oft as I think fit. It is no more than _willing_, and

straightway this or that idea arises in my fancy; and by the same power it

is obliterated and makes way for another. This making and unmaking of

ideas doth very properly denominate the mind active. Thus much is certain

and grounded on experience: but when we talk of unthinking agents, or of

exciting ideas exclusive of volition, we only amuse ourselves with

words(580).

‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐

29. But, whatever power I may have over my own thoughts, I find the ideas

actually perceived by Sense have not a like dependence on _my_ will. When

in broad daylight I open my eyes, it is not in my power to choose whether

I shall see or no, or to determine what particular objects shall present

themselves to my view: and so likewise as to the hearing and other senses;

the ideas imprinted on them are not creatures of _my_ will(581). There is

therefore some other Will or Spirit that produces them.

30. The ideas of Sense are more strong, lively, and distinct than those of

the Imagination(582); they have likewise a steadiness, order, and

coherence, and are not excited at random, as those which are the effects

of human wills often are, but in a regular train or series—the admirable

connexion whereof sufficiently testifies the wisdom and benevolence of its

Author. Now the set rules, or established methods, wherein the Mind we

depend on excites in us the ideas of Sense, are called _the laws of

nature_; and these we learn by experience, which teaches us that such and

such ideas are attended with such and such other ideas, in the ordinary

course of things.

31. This gives us a sort of foresight, which enables us to regulate our

actions for the benefit of life. And without this we should be eternally

at a loss: we could not know how to act anything that might procure us the

least pleasure, or remove the least pain of sense. That food nourishes,

sleep refreshes, and fire warms us; that to sow in the seed-time is the

way to reap in the harvest; and in general that to obtain such or such

ends, such or such means are conducive—all this we know, not by

discovering any _necessary connexion_ between our ideas, but only by the

observation of the _settled laws_ of nature; without which we should be

all in uncertainty and confusion, and a grown man no more know how to

manage himself in the affairs of life than an infant just born(583).

32. And yet this consistent uniform working, which so evidently displays

the Goodness and Wisdom of that Governing Spirit whose Will constitutes

the laws of nature, is so far from leading our thoughts to Him, that it

rather sends them wandering after second causes(584). For, when we

perceive certain ideas of Sense constantly followed by other ideas, and we

know this is not of our own doing, we forthwith attribute power and agency

to the ideas themselves, and make one the cause of another, than which

nothing can be more absurd and unintelligible. Thus, for example, having

observed that when we perceive by sight a certain round luminous figure,

we at the same time perceive by touch the idea or sensation called heat,

we do from thence conclude the sun to be the _cause_ of heat. And in like

manner perceiving the motion and collision of bodies to be attended with

sound, we are inclined to think the latter the _effect_ of the

former(585).

33. The ideas imprinted on the Senses by the Author of nature are called

_real things_: and those excited in the imagination, being less regular,

vivid, and constant, are more properly termed _ideas_ or _images of_

things, which they copy and represent. But then our _sensations_, be they

never so vivid and distinct, are nevertheless ideas(586): that is, they

exist in the mind, or are perceived by it, as truly as the ideas of its

own framing. The ideas of Sense are allowed to have more reality(587) in

them, that is, to be more strong, orderly, and coherent than the creatures

of the mind; but this is no argument that they exist without the mind.

They are also less dependent on the spirit or thinking substance which

perceives them, in that they are excited by the will of another and more

powerful Spirit; yet still they are _ideas_: and certainly no idea,

whether faint or strong, can exist otherwise than in a mind perceiving

it(588).

‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐

34. Before we proceed any farther it is necessary we spend some time in

answering Objections(589) which may probably be made against the

Principles we have hitherto laid down. In doing of which, if I seem too

prolix to those of quick apprehensions, I desire I may be excused, since

all men do not equally apprehend things of this nature; and I am willing

to be understood by every one.

_First_, then, it will be objected that by the foregoing principles all

that is real and substantial in nature is banished out of the world, and

instead thereof a chimerical scheme of _ideas_ takes place. All things

that exist exist only in the mind; that is, they are purely notional. What

therefore becomes of the sun, moon, and stars? What must we think of

houses, rivers, mountains, trees, stones; nay, even of our own bodies? Are

all these but so many chimeras and illusions on the fancy?—To all which,

and whatever else of the same sort may be objected, I answer, that by the

Principles premised we are not deprived of any one thing in nature.

Whatever we see, feel, hear, or any wise conceive or understand, remains

as secure as ever, and is as real as ever. There is a _rerum natura_, and

the distinction between realities and chimeras retains its full force.

This is evident from sect. 29, 30, and 33, where we have shewn what is

meant by _real things_, in opposition to _chimeras_ or _ideas of our own

framing_; but then they both equally exist in the mind, and in that

sense(590) are alike _ideas_.

35. I do not argue against the existence of any one thing that we can

apprehend, either by sense or reflection. That the things I see with my

eyes and touch with my hands do exist, really exist, I make not the least

question. The only thing whose existence we deny is that which

_philosophers_ call Matter or corporeal substance. And in doing of this

there is no damage done to the rest of mankind, who, I dare say, will

never miss it. The Atheist indeed will want the colour of an empty name to

support his impiety; and the Philosophers may possibly find they have lost

a great handle for trifling and disputation. [(591)But that is all the

harm that I can see done.]

36. If any man thinks this detracts from the existence or reality of

things, he is very far from understanding what hath been premised in the

plainest terms I could think of. Take here an abstract of what has been

said:—There are spiritual substances, minds, or human souls, which will or

excite ideas(592) in themselves at pleasure; but these are faint, weak,

and unsteady in respect of others they perceive by sense: which, being

impressed upon them according to certain rules or laws of nature, speak

themselves the effects of a Mind more powerful and wise than human

spirits(593). These latter are said to have _more reality_(594) in them

than the former;—by which is meant that they are more affecting, orderly,

and distinct, and that they are not fictions of the mind perceiving

them(595). And in this sense the sun that I see by day is the real sun,

and that which I imagine by night is the idea of the former. In the sense

here given of _reality_, it is evident that every vegetable, star,

mineral, and in general each part of the mundane system, is as much a

_real being_ by our principles as by any other. Whether others mean

anything by the term _reality_ different from what I do, I entreat them to

look into their own thoughts and see.

37. It will be urged that thus much at least is true, to wit, that we take

away all _corporeal substances_. To this my answer is, that if the word

_substance_ be taken in the vulgar sense, for a _combination_ of sensible

qualities, such as extension, solidity, weight, and the like—this we

cannot be accused of taking away: but if it be taken in a philosophic

sense, for the support of accidents or qualities without the mind—then

indeed I acknowledge that we take it away, if one may be said to take away

that which never had any existence, not even in the imagination(596).

38. But after all, say you, it sounds very harsh to say we eat and drink

ideas, and are clothed with ideas. I acknowledge it does so—the word

_idea_ not being used in common discourse to signify the several

combinations of sensible qualities which are called _things_; and it is

certain that any expression which varies from the familiar use of language

will seem harsh and ridiculous. But this doth not concern the truth of the

proposition, which in other words is no more than to say, we are fed and

clothed with those things which we perceive immediately by our

senses(597). The hardness or softness, the colour, taste, warmth, figure,

and suchlike qualities, which combined together(598) constitute the

several sorts of victuals and apparel, have been shewn to exist only in

the mind that perceives them: and this is all that is meant by calling

them _ideas_; which word, if it was as ordinarily used as _thing_, would

sound no harsher nor more ridiculous than it. I am not for disputing about

the propriety, but the truth of the expression. If therefore you agree

with me that we eat and drink and are clad with the immediate objects of

sense, which cannot exist unperceived or without the mind, I shall readily

grant it is more proper or conformable to custom that they should be

called _things_ rather than _ideas_.

39. If it be demanded why I make use of the word _idea_, and do not rather

in compliance with custom call them _things_; I answer, I do it for two

reasons:—First, because the term _thing_, in contradistinction to _idea_,

is generally supposed to denote somewhat existing without the mind:

Secondly, because _thing_ hath a more comprehensive signification than

_idea_, including spirits, or thinking things(599), as well as ideas.

Since therefore the objects of sense exist only in the mind, and are

withal thoughtless and inactive, I chose to mark them by the word _idea_;

which implies those properties(600).
