animal mechanism in the parts of animals; might not vegetables grow,

and shoot forth leaves of blossoms, and animals perform all their

motions as well without as with all that variety of internal parts

so elegantly contrived and put together; which, being ideas, have

nothing powerful or operative in them, nor have any necessary connexion

with the effects ascribed to them? If it be a Spirit that immediately

produces every effect by a fiat or act of his will, we must think all

that is fine and artificial in the works, whether of man or nature,

to be made in vain. By this doctrine, though an artist has made the

spring and wheels, and every movement of a watch, and adjusted them

in such a manner as he knew would produce the motions he designed,

yet he must think all this done to no purpose, and that it is an

Intelligence which directs the index, and points to the hour of the

day. If so, why may not the Intelligence do it, without his being at the

pains of making the movements and putting them together?

Why does not an

empty case serve as well as another? And how comes it to pass that

whenever there is any fault in the going of a watch, there is some

corresponding disorder to be found in the movements, which being mended

by a skilful hand all is right again? The like may be said of all the

clockwork of nature, great part whereof is so wonderfully fine and subtle

as scarce to be discerned by the best microscope. In short, it will be

asked, how, upon our principles, any tolerable account can be given, or

any final cause assigned of an innumerable multitude of bodies and

machines, framed with the most exquisite art, which in the common

philosophy have very apposite uses assigned them, and serve to explain

abundance of phenomena?

61. ANSWER.--To all which I answer, first, that though there were some

difficulties relating to the administration of Providence, and the uses

by it assigned to the several parts of nature, which I could not solve by

the foregoing principles, yet this objection could be of small weight

against the truth and certainty of those things which may be proved a

priori, with the utmost evidence and rigor of demonstration. Secondly,

but neither are the received principles free from the like difficulties;

for, it may still be demanded to what end God should take those

roundabout methods of effecting things by instruments and machines, which

no one can deny might have been effected by the mere command of His will

without all that apparatus; nay, if we narrowly consider it, we shall

find the objection may be retorted with greater force on those who hold

the existence of those machines without of mind; for it has been made

evident that solidity, bulk, figure, motion, and the like have no

activity or efficacy in them, so as to be capable of producing any one

effect in nature. See sect. 25. Whoever therefore supposes them to exist

(allowing the supposition possible) when they are not perceived does it

manifestly to no purpose; since the only use that is assigned to them, as

they exist unperceived, is that they produce those perceivable effects

which in truth cannot be ascribed to anything but Spirit.

62. (FOURTHLY.)--But, to come nigher the difficulty, it must be observed

that though the fabrication of all those parts and organs be not

absolutely necessary to the producing any effect, yet it is necessary

to the producing of things in a constant regular way according to

the laws of nature. There are certain general laws that run through

the whole chain of natural effects; these are learned by the observation

and study of nature, and are by men applied as well to the framing

artificial things for the use and ornament of life as to the

explaining various phenomena--which explication consists only in

showing the conformity any particular phenomenon has to the general

laws of nature, or, which is the same thing, in discovering the

uniformity there is in the production of natural effects; as will

be evident to whoever shall attend to the several instances wherein

philosophers pretend to account for appearances. That there is a

great and conspicuous use in these regular constant methods of

working observed by the Supreme Agent has been shown in sect. 31.

And it is no less visible that a particular size, figure, motion,

and disposition of parts are necessary, though not absolutely to

the producing any effect, yet to the producing it according to the

standing mechanical laws of nature. Thus, for instance, it cannot be

denied that God, or the Intelligence that sustains and rules the ordinary

course of things, might if He were minded to produce a miracle, cause all

the motions on the dial-plate of a watch, though nobody had ever made the

movements and put them in it: but yet, if He will act agreeably to the

rules of mechanism, by Him for wise ends established and maintained in

the creation, it is necessary that those actions of the watchmaker,

whereby he makes the movements and rightly adjusts them, precede the

production of the aforesaid motions; as also that any disorder in them be

attended with the perception of some corresponding disorder in the

movements, which being once corrected all is right again.

63. It may indeed on some occasions be necessary that the Author of

nature display His overruling power in producing some appearance out of

the ordinary series of things. Such exceptions from the general rules of

nature are proper to surprise and awe men into an acknowledgement of the

Divine Being; but then they are to be used but seldom, otherwise there is

a plain reason why they should fail of that effect.

Besides, God seems to

choose the convincing our reason of His attributes by the works of

nature, which discover so much harmony and contrivance in their make, and

are such plain indications of wisdom and beneficence in their Author,

rather than to astonish us into a belief of His Being by anomalous and

surprising events.

64. To set this matter in a yet clearer light, I shall observe that what

has been objected in sect. 60 amounts in reality to no more than

this:--ideas are not anyhow and at random produced, there being a certain

order and connexion between them, like to that of cause and effect; there

are also several combinations of them made in a very regular and

artificial manner, which seem like so many instruments in the hand of

nature that, being hid as it were behind the scenes, have a secret

operation in producing those appearances which are seen on the theatre of

the world, being themselves discernible only to the curious eye of the

philosopher. But, since one idea cannot be the cause of another, to what

purpose is that connexion? And, since those instruments, being barely

inefficacious perceptions in the mind, are not subservient to the

production of natural effects, it is demanded why they are made; or, in

other words, what reason can be assigned why God should make us, upon a

close inspection into His works, behold so great variety of ideas so

artfully laid together, and so much according to rule; it not being

credible that He would be at the expense (if one may so speak) of all

that art and regularity to no purpose.

65. To all which my answer is, first, that the connexion of ideas does

not imply the relation of cause and effect, but only of a mark or sign

with the thing signified. The fire which I see is not the cause of the

pain I suffer upon my approaching it, but the mark that forewarns me of

it. In like manner the noise that I hear is not the effect of this or

that motion or collision of the ambient bodies, but the sign thereof.

Secondly, the reason why ideas are formed into machines, that is,

artificial and regular combinations, is the same with that for combining

letters into words. That a few original ideas may be made to signify a

great number of effects and actions, it is necessary they be variously

combined together. And, to the end their use be permanent and universal,

these combinations must be made by rule, and with wise contrivance. By

this means abundance of information is conveyed unto us, concerning what

we are to expect from such and such actions and what methods are proper

to be taken for the exciting such and such ideas; which in effect is all

that I conceive to be distinctly meant when it is said that, by

discerning a figure, texture, and mechanism of the inward parts of

bodies, whether natural or artificial, we may attain to know the several

uses and properties depending thereon, or the nature of the thing.

66. PROPER EMPLOYMENT OF THE NATURAL PHILOSOPHER.--

Hence, it is evident

that those things which, under the notion of a cause co-operating

or concurring to the production of effects, are altogether inexplicable,

and run us into great absurdities, may be very naturally explained,

and have a proper and obvious use assigned to them, when they are

considered only as marks or signs for our information.

And it is

the searching after and endeavouring to understand those signs

instituted by the Author of Nature, that ought to be the employment of

the natural philosopher; and not the pretending to explain things by

corporeal causes, which doctrine seems to have too much estranged the

minds of men from that active principle, that supreme and wise Spirit "in

whom we live, move, and have our being."

67. TWELFTH OBJECTION.--ANSWER.--In the twelfth place, it may perhaps

be objected that--though it be clear from what has been said that

there can be no such thing as an inert, senseless, extended, solid,

figured, movable substance existing without the mind, such as

philosophers describe Matter--yet, if any man shall leave out of

his idea of matter the positive ideas of extension, figure, solidity

and motion, and say that he means only by that word an inert,

senseless substance, that exists without the mind or unperceived,

which is the occasion of our ideas, or at the presence whereof God is

pleased to excite ideas in us: it doth not appear but that Matter taken

in this sense may possibly exist. In answer to which I say, first, that

it seems no less absurd to suppose a substance without accidents, than it

is to suppose accidents without a substance. But secondly, though we

should grant this unknown substance may possibly exist, yet where can it

be supposed to be? That it exists not in the mind is agreed; and that it

exists not in place is no less certain--since all place or extension

exists only in the mind, as has been already proved. It remains

therefore that it exists nowhere at all.

68. MATTER SUPPORTS NOTHING, AN ARGUMENT AGAINST ITS

EXISTENCE.--Let us

examine a little the description that is here given us of

matter. It neither acts, nor perceives, nor is perceived; for this is all

that is meant by saying it is an inert, senseless, unknown substance;

which is a definition entirely made up of negatives, excepting only the

relative notion of its standing under or supporting. But then it must be

observed that it supports nothing at all, and how nearly this comes to

the description of a nonentity I desire may be considered. But, say you,

it is the unknown occasion, at the presence of which ideas are excited in

us by the will of God. Now, I would fain know how anything can be present

to us, which is neither perceivable by sense nor reflexion, nor capable

of producing any idea in our minds, nor is at all extended, nor has any

form, nor exists in any place. The words "to be present," when thus

applied, must needs be taken in some abstract and strange meaning, and

which I am not able to comprehend.

69. Again, let us examine what is meant by occasion. So far as I can

gather from the common use of language, that word signifies either the

agent which produces any effect, or else something that is observed to

accompany or go before it in the ordinary course of things. But when it

is applied to Matter as above described, it can be taken in neither of

those senses; for Matter is said to be passive and inert, and so cannot

be an agent or efficient cause. It is also unperceivable, as being devoid

of all sensible qualities, and so cannot be the occasion of our

perceptions in the latter sense: as when the burning my finger is said to

be the occasion of the pain that attends it. What therefore can be meant

by calling matter an occasion? The term is either used in no sense at

all, or else in some very distant from its received signification.

70. You will Perhaps say that Matter, though it be not perceived by us,

is nevertheless perceived by God, to whom it is the occasion of exciting

ideas in our minds. For, say you, since we observe our sensations to be

imprinted in an orderly and constant manner, it is but reasonable to

suppose there are certain constant and regular occasions of their being

produced. That is to say, that there are certain permanent and distinct

parcels of Matter, corresponding to our ideas, which, though they do not

excite them in our minds, or anywise immediately affect us, as being

altogether passive and unperceivable to us, they are nevertheless to God,

by whom they art perceived, as it were so many occasions to remind Him

when and what ideas to imprint on our minds; that so things may go on in

a constant uniform manner.

71. In answer to this, I observe that, as the notion of Matter is here

stated, the question is no longer concerning the existence of a thing

distinct from Spirit and idea, from perceiving and being perceived; but

whether there are not certain ideas of I know not what sort, in the mind

of God which are so many marks or notes that direct Him how to produce

sensations in our minds in a constant and regular method--much after the

same manner as a musician is directed by the notes of music to produce

that harmonious train and composition of sound which is called a tune,

though they who hear the music do not perceive the notes, and may be

entirely ignorant of them. But, this notion of Matter seems too

extravagant to deserve a confutation. Besides, it is in effect no

objection against what we have advanced, viz. that there is no senseless

unperceived substance.

72. THE ORDER OF OUR PERCEPTIONS SHOWS THE GOODNESS OF

GOD, BUT

AFFORDS NO PROOF OF THE EXISTENCE OF MATTER.--If we follow the light

of reason, we shall, from the constant uniform method of our

sensations, collect the goodness and wisdom of the Spirit who

excites them in our minds; but this is all that I can see reasonably

concluded from thence. To me, I say, it is evident that the being of a

spirit infinitely wise, good, and powerful is abundantly sufficient to

explain all the appearances of nature. But, as for inert, senseless

Matter, nothing that I perceive has any the least connexion with it, or

leads to the thoughts of it. And I would fain see any one explain any the

meanest phenomenon in nature by it, or show any manner of reason, though

in the lowest rank of probability, that he can have for its existence, or

even make any tolerable sense or meaning of that supposition. For, as to

its being an occasion, we have, I think, evidently shown that with regard

to us it is no occasion. It remains therefore that it must be, if at all,

the occasion to God of exciting ideas in us; and what this amounts to we

have just now seen.

73. It is worth while to reflect a little on the motives which induced

men to suppose the existence of material substance; that so having

observed the gradual ceasing and expiration of those motives or reasons,

we may proportionably withdraw the assent that was grounded on them.

First, therefore, it was thought that colour, figure, motion, and the

rest of the sensible qualities or accidents, did really exist without the

mind; and for this reason it seemed needful to suppose some unthinking

substratum or substance wherein they did exist, since they could not be

conceived to exist by themselves. Afterwards, in process of time, men

being convinced that colours, sounds, and the rest of the sensible,

secondary qualities had no existence without the mind, they stripped this

substratum or material substance of those qualities, leaving only the

primary ones, figure, motion, and suchlike, which they still conceived to

exist without the mind, and consequently to stand in need of a material

support. But, it having been shown that none even of these can possibly

exist otherwise than in a Spirit or Mind which perceives them it follows

that we have no longer any reason to suppose the being of Matter; nay,

that it is utterly impossible there should be any such thing, so long as

that word is taken to denote an unthinking substratum of qualities or

accidents wherein they exist without the mind.

74. But though it be allowed by the materialists themselves that Matter

was thought of only for the sake of supporting accidents, and, the reason

entirely ceasing, one might expect the mind should naturally, and without

any reluctance at all, quit the belief of what was solely grounded

thereon; yet the prejudice is riveted so deeply in our thoughts, that we

can scarce tell how to part with it, and are therefore inclined, since

the thing itself is indefensible, at least to retain the name, which we

apply to I know not what abstracted and indefinite notions of being, or

occasion, though without any show of reason, at least so far as I can

see. For, what is there on our part, or what do we perceive, amongst all

the ideas, sensations, notions which are imprinted on our minds, either

by sense or reflexion, from whence may be inferred the existence of an

inert, thoughtless, unperceived occasion? and, on the other hand, on the

part of an All-sufficient Spirit, what can there be that should make us

believe or even suspect He is directed by an inert occasion to excite

ideas in our minds?

75. ABSURDITY OF CONTENDING FOR THE EXISTENCE OF MATTER

AS THE OCCASION

OF IDEAS.--It is a very extraordinary instance of the force of prejudice,

and much to be lamented, that the mind of man retains so great a fondness,

against all the evidence of reason, for a stupid thoughtless somewhat, by

the interposition whereof it would as it were screen itself from the

Providence of God, and remove it farther off from the affairs of the

world. But, though we do the utmost we can to secure the belief of

Matter, though, when reason forsakes us, we endeavour to support our

opinion on the bare possibility of the thing, and though we indulge

ourselves in the full scope of an imagination not regulated by reason to

make out that poor possibility, yet the upshot of all is, that there are

certain unknown Ideas in the mind of God; for this, if anything, is all

that I conceive to be meant by occasion with regard to God. And this at

the bottom is no longer contending for the thing, but for the name.

76. Whether therefore there are such Ideas in the mind of God, and

whether they may be called by the name Matter, I shall not dispute. But,

if you stick to the notion of an unthinking substance or support of

extension, motion, and other sensible qualities, then to me it is most

evidently impossible there should be any such thing, since it is a plain

repugnancy that those qualities should exist in or be supported by an

unperceiving substance.

77. THAT A SUBSTRATUM NOT PERCEIVED, MAY EXIST, UNIMPORTANT.--But,

say you, though it be granted that there is no thoughtless support

of extension and the other qualities or accidents which we perceive,

yet there may perhaps be some inert, unperceiving substance or

substratum of some other qualities, as incomprehensible to us as colours

are to a man born blind, because we have not a sense adapted to them.

But, if we had a new sense, we should possibly no more doubt of their

existence than a blind man made to see does of the existence of light and

colours. I answer, first, if what you mean by the word Matter be only the

unknown support of unknown qualities, it is no matter whether there is

such a thing or no, since it no way concerns us; and I do not see the

advantage there is in disputing about what we know not what, and we know

not why.

78. But, secondly, if we had a new sense it could only furnish us with

new ideas or sensations; and then we should have the same reason against

their existing in an unperceiving substance that has been already offered

with relation to figure, motion, colour and the like.

Qualities, as has

been shown, are nothing else but sensations or ideas, which exist only in

a mind perceiving them; and this is true not only of the ideas we are

acquainted with at present, but likewise of all possible ideas

whatsoever.

79. But, you will insist, what if I have no reason to believe the

existence of Matter? what if I cannot assign any use to it or explain

anything by it, or even conceive what is meant by that word? yet still it

is no contradiction to say that Matter exists, and that this Matter is in

general a substance, or occasion of ideas; though indeed to go about to

unfold the meaning or adhere to any particular explication of those words

may be attended with great difficulties. I answer, when words are used

without a meaning, you may put them together as you please without danger

of running into a contradiction. You may say, for example, that twice two

is equal to seven, so long as you declare you do not take the words of

that proposition in their usual acceptation but for marks of you know not

what. And, by the same reason, you may say there is an inert thoughtless

substance without accidents which is the occasion of our ideas. And we

shall understand just as much by one proposition as the other.

80. In the last place, you will say, what if we give up the cause of

material Substance, and stand to it that Matter is an unknown

somewhat--neither substance nor accident, spirit nor idea, inert,

thoughtless, indivisible, immovable, unextended, existing in no place.

For, say you, whatever may be urged against substance or occasion, or any

other positive or relative notion of Matter, has no place at all, so

long as this negative definition of Matter is adhered to. I answer, you

may, if so it shall seem good, use the word "Matter" in the same sense as

other men use "nothing," and so make those terms convertible in your

style. For, after all, this is what appears to me to be the result of

that definition, the parts whereof when I consider with attention, either

collectively or separate from each other, I do not find that there is any

kind of effect or impression made on my mind different from what is

excited by the term nothing.

81. You will reply, perhaps, that in the fore-said definition is included

what doth sufficiently distinguish it from nothing--the positive abstract

idea of quiddity, entity, or existence. I own, indeed, that those who

pretend to the faculty of framing abstract general ideas do talk as if

they had such an idea, which is, say they, the most abstract and general

notion of all; that is, to me, the most incomprehensible of all others.

That there are a great variety of spirits of different orders and

capacities, whose faculties both in number and extent are far exceeding

those the Author of my being has bestowed on me, I see no reason to deny.

And for me to pretend to determine by my own few, stinted narrow inlets

of perception, what ideas the inexhaustible power of the Supreme Spirit

may imprint upon them were certainly the utmost folly and

pre
