qualities of the image; and this inference of the judgment he confounds

with sensation, as is common on other occasions. Now it is evident,

that the inference of the judgment is here much more lively than what

is usual in our common reasonings, and that a man has a more vivid

conception of the vast extent of the ocean from the image he receives by

the eye, when he stands on the top of the high promontory, than merely

from hearing the roaring of the waters. He feels a more sensible

pleasure from its magnificence; which is a proof of a more lively idea:

And he confounds his judgment with sensation, which is another proof of

it. But as the inference is equally certain and immediate in both cases,

this superior vivacity of our conception in one case can proceed from

nothing but this, that in drawing an inference from the sight, beside

the customary conjunction, there is also a resemblance betwixt the image

and the object we infer; which strengthens the relation, and conveys the

vivacity of the impression to the related idea with an easier and more

natural movement.

No weakness of human nature is more universal and conspicuous than what

we commonly call CREDULITY, or a too easy faith in the testimony of

others; and this weakness is also very naturally accounted for from the

influence of resemblance. When we receive any matter of fact upon human

testimony, our faith arises from the very same origin as our inferences

from causes to effects, and from effects to causes; nor is there

anything but our experience of the governing principles of human nature,

which can give us any assurance of the veracity of men.

But though

experience be the true standard of this, as well as of all other

judgments, we seldom regulate ourselves entirely by it; but have a

remarkable propensity to believe whatever is reported, even concerning

apparitions, enchantments, and prodigies, however contrary to daily

experience and observation. The words or discourses of others have an

intimate connexion with certain ideas in their mind; and these ideas

have also a connexion with the facts or objects, which they represent.

This latter connexion is generally much over-rated, and commands our

assent beyond what experience will justify; which can proceed from

nothing beside the resemblance betwixt the ideas and the facts. Other

effects only point out their causes in an oblique manner; but the

testimony of men does it directly, and is to be considered as an image

as well as an effect. No wonder, therefore, we are so rash in drawing

our inferences from it, and are less guided by experience in our

judgments concerning it, than in those upon any other subject.

As resemblance, when conjoined with causation, fortifies our reasonings;

so the want of it in any very great degree is able almost entirely to

destroy them. Of this there is a remarkable instance in the universal

carelessness and stupidity of men with regard to a future state, where

they show as obstinate an incredulity, as they do a blind credulity on

other occasions. There is not indeed a more ample matter of wonder

to the studious, and of regret to the pious man, than to observe

the negligence of the bulk of mankind concerning their approaching

condition; and it is with reason, that many eminent theologians have not

scrupled to affirm, that though the vulgar have no formal principles

of infidelity, yet they are really infidels in their hearts, and have

nothing like what we can call a belief of the eternal duration of their

souls. For let us consider on the one hand what divines have displayed

with such eloquence concerning the importance of eternity; and at the

same time reflect, that though in matters of rhetoric we ought to lay

our account with some exaggeration, we must in this case allow, that the

strongest figures are infinitely inferior to the subject: And after this

let us view on the other hand, the prodigious security of men in this

particular: I ask, if these people really believe what is inculcated on

them, and what they pretend to affirm; and the answer is obviously in

the negative. As belief is an act of the mind arising from custom, it

is not strange the want of resemblance should overthrow what custom has

established, and diminish the force of the idea, as much as that latter

principle encreases it. A future state is so far removed from our

comprehension, and we have so obscure an idea of the manner, in which we

shall exist after the dissolution of the body, that all the reasons we

can invent, however strong in themselves, and however much assisted

by education, are never able with slow imaginations to surmount this

difficulty, or bestow a sufficient authority and force on the idea. I

rather choose to ascribe this incredulity to the faint idea we form

of our future condition, derived from its want of resemblance to the

present life, than to that derived from its remoteness.

For I observe,

that men are everywhere concerned about what may happen after their

death, provided it regard this world; and that there are few to whom

their name, their family, their friends, and their country are in any

period of time entirely indifferent.

And indeed the want of resemblance in this case so entirely destroys

belief, that except those few, who upon cool reflection on the

importance of the subject, have taken care by repeated meditation to

imprint in their minds the arguments for a future state, there scarce

are any, who believe the immortality of the soul with a true and

established judgment; such as is derived from the testimony of

travellers and historians. This appears very conspicuously wherever

men have occasion to compare the pleasures and pains, the rewards and

punishments of this life with those of a future; even though the case

does not concern themselves, and there is no violent passion to disturb

their judgment. The Roman Clatholicks are certainly the most zealous of

any sect in the Christian world; and yet you'll find few among the

more sensible people of that communion who do not blame the

Gunpowder-treason, and the massacre of St. Bartholomew, as cruel and

barbarous, though projected or executed against those very people, whom

without any scruple they condemn to eternal and infinite punishments.

All we can say in excuse for this inconsistency is, that they really do

not believe what they affirm concerning a future state; nor is there any

better proof of it than the very inconsistency.

We may add to this a remark; that in matters of religion men take a

pleasure in being terrifyed, and that no preachers are so popular, as

those who excite the most dismal and gloomy passions. In the common

affairs of life, where we feel and are penetrated with the solidity of

the subject, nothing can be more disagreeable than fear and terror; and

it is only in dramatic performances and in religious discourses, that

they ever give pleasure. In these latter cases the imagination reposes

itself indolently on the idea; and the passion, being softened by the

want of belief in the subject, has no more than the agreeable effect of

enlivening the mind, and fixing the attention.

The present hypothesis will receive additional confirmation, if we

examine the effects of other kinds of custom, as well as of other

relations. To understand this we must consider, that custom, to which

I attribute all belief and reasoning, may operate upon the mind in

invigorating an idea after two several ways. For supposing that in all

past experience we have found two objects to have been always conjoined

together, it is evident, that upon the appearance of one of these

objects in an impression, we must from custom make an easy transition to

the idea of that object, which usually attends it; and by means of the

present impression and easy transition must conceive that idea in a

stronger and more lively manner, than we do any loose floating image of

the fancy. But let us next suppose, that a mere idea alone, without any

of this curious and almost artificial preparation, should frequently

make its appearance in the mind, this idea must by degrees acquire a

facility and force; and both by its firm hold and easy introduction

distinguish itself from any new and unusual idea. This is the only

particular, in which these two kinds of custom agree; and if it appear,

that their effects on the judgment, are similar and proportionable, we

may certainly conclude, that the foregoing explication of that faculty

is satisfactory. But can we doubt of this agreement in their influence

on the judgment, when we consider the nature and effects Of EDUCATION?

All those opinions and notions of things, to which we have been

accustomed from our infancy, take such deep root, that it is impossible

for us, by all the powers of reason and experience, to eradicate them;

and this habit not only approaches in its influence, but even on

many occasions prevails over that which a-rises from the constant and

inseparable union of causes and effects. Here we most not be contented

with saying, that the vividness of the idea produces the belief: We must

maintain that they are individually the same. The frequent repetition

of any idea infixes it in the imagination; but coued never possibly

of itself produce belief, if that act of the mind was, by the original

constitution of our natures, annexed only to a reasoning and comparison

of ideas. Custom may lead us into some false comparison of ideas. This

is the utmost effect we can conceive of it. But it is certain it coued

never supply the place of that comparison, nor produce any act of the

mind, which naturally belonged to that principle.

A person, that has lost a leg or an arm by amputation, endeavours for a

long time afterwards to serve himself with them. After the death of any

one, it is a common remark of the whole family, but especially of the

servants, that they can scarce believe him to be dead, but still

imagine him to be in his chamber or in any other place, where they

were accustomed to find him. I have often heard in conversation, after

talking of a person, that is any way celebrated, that one, who has

no acquaintance with him, will say, I have never seen such-a-one, but

almost fancy I have; so often have I heard talk of him.

All these are

parallel instances.

If we consider this argument from EDUCATION in a proper light, it will

appear very convincing; and the more so, that it is founded on one

of the most common phaenomena, that is any where to be met with. I am

persuaded, that upon examination we shall find more than one half of

those opinions, that prevail among mankind, to be owing to education,

and that the principles, which are thus implicitely embraced,

overballance those, which are owing either to abstract reasoning or

experience. As liars, by the frequent repetition of their lies, come at

last to remember them; so the judgment, or rather the imagination, by

the like means, may have ideas so strongly imprinted on it, and conceive

them in so full a light, that they may operate upon the mind in the same

manner with those, which the senses, memory or reason present to us. But

as education is an artificial and not a natural cause, and as its maxims

are frequently contrary to reason, and even to themselves in different

times and places, it is never upon that account recognized by

philosophers; though in reality it be built almost on the same

foundation of custom and repetition as our reasonings from causes and

effects.

[Footnote 7. In general we may observe, that as our assent

to all probable reasonings is founded on the vivacity of

ideas, It resembles many of those whimsies and prejudices,

which are rejected under the opprobrious character of being

the offspring of the imagination. By this expression it

appears that the word, imagination, is commonly usd in two

different senses; and tho nothing be more contrary to true

philosophy, than this inaccuracy, yet in the following

reasonings I have often been obligd to fall into it. When I

oppose the Imagination to the memory, I mean the faculty, by

which we form our fainter ideas. When I oppose it to reason,

I mean the same faculty, excluding only our demonstrative

and probable reasonings. When I oppose it to neither, it is

indifferent whether it be taken in the larger or more

limited sense, or at least the context will sufficiently

explain the meaning.]

SECT. X. OF THE INFLUENCE OF BELIEF.

But though education be disclaimed by philosophy, as a fallacious ground

of assent to any opinion, it prevails nevertheless in the world, and

is the cause why all systems are apt to be rejected at first as new

and unusual. This perhaps will be the fate of what I have here advanced

concerning belief, and though the proofs I have produced appear to

me perfectly conclusive, I expect not to make many proselytes to

my opinion. Men will scarce ever be persuaded, that effects of

such consequence can flow from principles, which are seemingly so

inconsiderable, and that the far greatest part of our reasonings with

all our actions and passions, can be derived from nothing but custom and

habit. To obviate this objection, I shall here anticipate a little what

would more properly fall under our consideration afterwards, when we

come to treat of the passions and the sense of beauty.

There is implanted in the human mind a perception of pain and pleasure,

as the chief spring and moving principle of all its actions. But pain

and pleasure have two ways of making their appearance in the mind; of

which the one has effects very different from the other.

They may either

appear in impression to the actual feeling, or only in idea, as at

present when I mention them. It is evident the influence of these upon

our actions is far from being equal. Impressions always actuate the

soul, and that in the highest degree; but it is not every idea which

has the same effect. Nature has proceeded with caution in this came, and

seems to have carefully avoided the inconveniences of two extremes.

Did impressions alone influence the will, we should every moment of our

lives be subject to the greatest calamities; because, though we foresaw

their approach, we should not be provided by nature with any principle

of action, which might impel us to avoid them. On the other hand,

did every idea influence our actions, our condition would not be much

mended. For such is the unsteadiness and activity of thought, that

the images of every thing, especially of goods and evils, are always

wandering in the mind; and were it moved by every idle conception of

this kind, it would never enjoy a moment's peace and tranquillity.

Nature has, therefore, chosen a medium, and has neither bestowed on

every idea of good and evil the power of actuating the will, nor yet has

entirely excluded them from this influence. Though an idle fiction has

no efficacy, yet we find by experience, that the ideas of those objects,

which we believe either are or will be existent, produce in a lesser

degree the same effect with those impressions, which are immediately

present to the senses and perception. The effect, then, of belief is to

raise up a simple idea to an equality with our impressions, and bestow

on it a like influence on the passions. This effect it can only have by

making an idea approach an impression in force and vivacity. For as the

different degrees of force make all the original difference betwixt an

impression and an idea, they must of consequence be the source of all

the differences in the effects of these perceptions, and their removal,

in whole or in part, the cause of every new resemblance they acquire.

Wherever we can make an idea approach the impressions in force and

vivacity, it will likewise imitate them in its influence on the mind;

and vice versa, where it imitates them in that influence, as in the

present case, this must proceed from its approaching them in force and

vivacity. Belief, therefore, since it causes an idea to imitate

the effects of the impressions, must make it resemble them in these

qualities, and is nothing but A MORE VIVID AND INTENSE

CONCEPTION OF

ANY IDEA. This, then, may both serve as an additional argument for

the present system, and may give us a notion after what manner our

reasonings from causation are able to operate on the will and passions.

As belief is almost absolutely requisite to the exciting our passions,

so the passions in their turn are very favourable to belief; and not

only such facts as convey agreeable emotions, but very often such as

give pain, do upon that account become more readily the objects of faith

and opinion. A coward, whose fears are easily awakened, readily assents

to every account of danger he meets with; as a person of a sorrowful and

melancholy disposition is very credulous of every thing, that nourishes

his prevailing passion. When any affecting object is presented, it

gives the alarm, and excites immediately a degree of its proper passion;

especially in persons who are naturally inclined to that passion. This

emotion passes by an easy transition to the imagination; and diffusing

itself over our idea of the affecting object, makes us form that

idea with greater force and vivacity, and consequently assent to it,

according to the precedent system. Admiration and surprize have the same

effect as the other passions; and accordingly we may observe, that

among the vulgar, quacks and projectors meet with a more easy faith upon

account of their magnificent pretensions, than if they kept themselves

within the bounds of moderation. The first astonishment, which naturally

attends their miraculous relations, spreads itself over the whole soul,

and so vivifies and enlivens the idea, that it resembles the inferences

we draw from experience. This is a mystery, with which we may be already

a little acquainted, and which we shall have farther occasion to be let

into in the progress of this treatise.

After this account of the influence of belief on the passions, we shall

find less difficulty in explaining its effects on the imagination,

however extraordinary they may appear. It is certain we cannot take

pleasure in any discourse, where our judgment gives no assent to those

images which are presented to our fancy. The conversation of those who

have acquired a habit of lying, though in affairs of no moment, never

gives any satisfaction; and that because those ideas they present to us,

not being attended with belief, make no impression upon the mind. Poets

themselves, though liars by profession, always endeavour to give an air

of truth to their fictions; and where that is totally neglected, their

performances, however ingenious, will never be able to afford much

pleasure. In short, we may observe, that even when ideas have no manner

of influence on the will and passions, truth and reality are still

requisite, in order to make them entertaining to the imagination.

But if we compare together all the phenomena that occur on this head,

we shall find, that truth, however necessary it may seem in all works

of genius, has no other effect than to procure an easy reception for the

ideas, and to make the mind acquiesce in them with satisfaction, or at

least without reluctance. But as this is an effect, which may easily be

supposed to flow from that solidity and force, which, according to

my system, attend those ideas that are established by reasonings from

causation; it follows, that all the influence of belief upon the fancy

may be explained from that system. Accordingly we may observe, that

wherever that influence arises from any other principles beside truth or

reality, they supply its place, and give an equal entertainment to

the imagination. Poets have formed what they call a poetical system of

things, which though it be believed neither by themselves nor readers,

is commonly esteemed a sufficient foundation for any fiction. We have

been so much accustomed to the names of MARS, JUPITER, VENUS, that

in the same manner as education infixes any opinion, the constant

repetition of these ideas makes them enter into the mind with facility,

and prevail upon the fancy, without influencing the judgment. In like

manner tragedians always borrow their fable, or at least the names of

their principal actors, from some known passage in history; and that not

in order to deceive the spectators; for they will frankly confess, that

truth is not in any circumstance inviolably observed: but in order

to procure a more easy reception into the imagination for those

extraordinary events, which they represent. But this is a precaution,

which is not required of comic poets, whose personages and incidents,

being of a more familiar kind, enter easily into the conception, and are

received without any such formality, even though at first night they be

known to be fictitious, and the pure offspring of the fancy.

This mixture of truth and falshood in the fables of tragic poets not

only serves our present purpose, by shewing, that the imagination can be

satisfyed without any absolute belief or assurance; but may in another

view be regarded as a very strong confirmation of this system. It is

evident, that poets make use of this artifice of borrowing the names

of their persons, and the chief events of their poems, from history, in

order to procure a more easy reception for the whole, and cause it

to make a deeper impression on the fancy and affections.

The several

incidents of the piece acquire a kind of relation by being united into

one poem or representation; and if any of these incidents be an object

of belief, it bestows a force and vivacity on the others, which are

related to it. The vividness of the first conception diffuses itself

along the relations, and is conveyed, as by so many pipes or canals,

to every idea that has any communication with the primary one. This,

indeed, can never amount to a perfect assurance; and that because

the union among the ideas is, in a manner, accidental: But still it

approaches so near, in its influence, as may convince us, that they

are derived from the same origin. Belief must please the imagination

by means of the force and vivacity which attends it; since every idea,

which has force and vivacity, is found to be agreeable to that faculty.

To confirm this we may observe, that the assistance is mutual betwixt

the judgment and fancy, as well as betwixt the judgment and passion;

and that belief not only gives vigour to the imagination, but that a

vigorous and strong imagination is of all talents the most proper to

procure belief and authority. It is difficult for us to withhold our

assent from what is painted out to us in all the colours of eloquence;

and the vivacity produced by the fancy is in many cases greater than

that which arises from custom and experience. We are hurried away by the

lively imagination of our author or companion; and even he himself is

often a victim to his own fire and genius.

Nor will it be amiss to remark, that as a lively imagination very often

degenerates into madness or folly, and bears it a great resemblance in

its operations; so they influence the judgment after the same manner,

and produce belief from the very same principles. When the imagination,

from any extraordinary ferment of the blood and spirits, acquires such a

vivacity as disorders
