CHAPTER VII.

OF SIMPLE IDEAS OF BOTH SENSATION AND REFLECTION.

1. Ideas of Pleasure and Pain.

There be other simple ideas which convey themselves into the mind by

all the ways of sensation and reflection, _viz_.

_Pleasure_ or _Delight_, and its opposite,

_Pain_, or _Uneasiness;_

_Power;_

_Existence;_

_Unity_ mix with almost all our other Ideas.

2. Delight or uneasiness, one or other of them, join themselves to

almost all our ideas both of sensation and reflection: and there is

scarce any affection of our senses from without, any retired thought of

our mind within, which is not able to produce in us pleasure or pain.

By pleasure and pain, I would be understood to signify, whatsoever

delights or molests us; whether it arises from the thoughts of our

minds, or anything operating on our bodies. For, whether we call it;

satisfaction, delight, pleasure, happiness, &c., on the one side, or

uneasiness, trouble, pain, torment, anguish, misery, &c., the other,

they are still but different degrees of the same thing, and belong to

the ideas of pleasure and pain, delight or uneasiness; which are the

names I shall most commonly use for those two sorts of ideas.

3. As motives of our actions.

The infinite wise Author of our being, having given us the power over

several parts of our bodies, to move or keep them at rest as we think

fit; and also, by the motion of them, to move ourselves and other

contiguous bodies, in which consist all the actions of our body: having

also given a power to our minds, in several instances, to choose,

amongst its ideas, which it will think on, and to pursue the inquiry of

this or that subject with consideration and attention, to excite us to

these actions of thinking and motion that we are capable of,—has been

pleased to join to several thoughts, and several sensations a

perception of delight. If this were wholly separated from all our

outward sensations, and inward thoughts, we should have no reason to

prefer one thought or action to another; negligence to attention, or

motion to rest. And so we should neither stir our bodies, nor employ

our minds, but let our thoughts (if I may so call it) run adrift,

without any direction or design, and suffer the ideas of our minds,

like unregarded shadows, to make their appearances there, as it

happened, without attending to them. In which state man, however

furnished with the faculties of understanding and will, would be a very

idle, inactive creature, and pass his time only in a lazy, lethargic

dream. It has therefore pleased our wise Creator to annex to several

objects, and the ideas which we receive from them, as also to several

of our thoughts, a concomitant pleasure, and that in several objects,

to several degrees, that those faculties which he had endowed us with

might not remain wholly idle and unemployed by us.

4. An end and use of pain.

Pain has the same efficacy and use to set us on work that pleasure has,

we being as ready to employ our faculties to avoid that, as to pursue

this: only this is worth our consideration, that pain is often produced

by the same objects and ideas that produce pleasure in us. This their

near conjunction, which makes us often feel pain in the sensations

where we expected pleasure, gives us new occasion of admiring the

wisdom and goodness of our Maker, who, designing the preservation of

our being, has annexed pain to the application of many things to our

bodies, to warn us of the harm that they will do, and as advices to

withdraw from them. But he, not designing our preservation barely, but

the preservation of every part and organ in its perfection, hath in

many cases annexed pain to those very ideas which delight us. Thus

heat, that is very agreeable to us in one degree, by a little greater

increase of it proves no ordinary torment: and the most pleasant of all

sensible objects, light itself, if there be too much of it, if

increased beyond a due proportion to our eyes, causes a very painful

sensation. Which is wisely and favourably so ordered by nature, that

when any object does, by the vehemency of its operation, disorder the

instruments of sensation, whose structures cannot but be very nice and

delicate, we might, by the pain, be warned to withdraw, before the

organ be quite put out of order, and so be unfitted for its proper

function for the future. The consideration of those objects that

produce it may well persuade us, that this is the end or use of pain.

For, though great light be insufferable to our eyes, yet the highest

degree of darkness does not at all disease them: because that, causing

no disorderly motion in it, leaves that curious organ unharmed in its

natural state. But yet excess of cold as well as heat pains us: because

it is equally destructive to that temper which is necessary to the

preservation of life, and the exercise of the several functions of the

body, and which consists in a moderate degree of warmth; or, if you

please, a motion of the insensible parts of our bodies, confined within

certain bounds.

5. Another end.

Beyond all this, we may find another reason why God hath scattered up

and down several degrees of pleasure and pain, in all the things that

environ and affect us; and blended them together in almost all that our

thoughts and senses have to do with;—that we, finding imperfection,

dissatisfaction, and want of complete happiness, in all the enjoyments

which the creatures can afford us, might be led to seek it in the

enjoyment of Him with whom there is fullness of joy, and at whose right

hand are pleasures for evermore.

6. Goodness of God in annexing pleasure and pain to our other ideas.

Though what I have here said may not, perhaps, make the ideas of

pleasure and pain clearer to us than our own experience does, which is

the only way that we are capable of having them; yet the consideration

of the reason why they are annexed to so many other ideas, serving to

give us due sentiments of the wisdom and goodness of the Sovereign

Disposer of all things, may not be unsuitable to the main end of these

inquiries: the knowledge and veneration of him being the chief end of

all our thoughts, and the proper business of all understandings.

7. Ideas of Existence and Unity.

EXISTENCE and UNITY are two other ideas that are suggested to the

understanding by every object without, and every idea within. When

ideas are in our minds, we consider them as being actually there, as

well as we consider things to be actually without us;—which is, that

they exist, or have existence. And whatever we can consider as one

thing, whether a real being or idea, suggests to the understanding the

idea of unity.

8. Idea of Power.

POWER also is another of those simple ideas which we receive from

sensation and reflection. For, observing in ourselves that we do and

can think, and that we can at pleasure move several parts of our bodies

which were at rest; the effects, also, that natural bodies are able to

produce in one another, occurring every moment to our senses,—we both

these ways get the idea of power.

9. Idea of Succession.

Besides these there is another idea, which, though suggested by our

senses, yet is more constantly offered to us by what passes in our

minds; and that is the idea of SUCCESSION. For if we look immediately

into ourselves, and reflect on what is observable there, we shall find

our ideas always, whilst we are awake, or have any thought, passing in

train, one going and another coming, without intermission.

10. Simple Ideas the materials of all our Knowledge.

These, if they are not all, are at least (as I think) the most

considerable of those simple ideas which the mind has, out of which is

made all its other knowledge; all which it receives only by the two

forementioned ways of sensation and reflection.

Nor let any one think these too narrow bounds for the capacious mind of

man to expatiate in, which takes its flight further than the stars, and

cannot be confined by the limits of the world; that extends its

thoughts often even beyond the utmost expansion of Matter, and makes

excursions into that incomprehensible Inane. I grant all this, but

desire any one to assign any SIMPLE IDEA which is not received from one

of those inlets before mentioned, or any COMPLEX IDEA not made out of

those simple ones. Nor will it be so strange to think these few simple

ideas sufficient to employ the quickest thought, or largest capacity;

and to furnish the materials of all that various knowledge, and more

various fancies and opinions of all mankind, if we consider how many

words may be made out of the various composition of twenty-four

letters; or if, going one step further, we will but reflect on the

variety of combinations that may be made with barely one of the

above-mentioned ideas, viz. number, whose stock is inexhaustible and

truly infinite: and what a large and immense field doth extension alone

afford the mathematicians?
