SECTION V.

OF THE OBLIGATION OF PROMISES.

That the rule of morality, which enjoins the performance of

promises, is not _natural_, will sufficiently appear from these two

propositions, which I proceed to prove, viz. _that a promise would not

be intelligible before human conventions had established it; and that

even if it were intelligible, it would not be attended with any moral

obligation_.

I say, _first_, that a promise is not intelligible naturally, nor

antecedent to human conventions; and that a man, unacquainted with

society, could never enter into any engagements with another, even

though they could perceive each other's thoughts by intuition. If

promises be natural and intelligible, there must be some act of the

mind attending these words, I _promise_; and on this act of the mind

must the obligation depend. Let us therefore run over all the faculties

of the soul, and see which of them is exerted in our promises.

The act of the mind, expressed by a promise, is not a _resolution_ to

perform any thing; for that alone never imposes any obligation. Nor is

it a _desire_ of such a performance; for we may bind ourselves without

such a desire, or even with an aversion, declared and avowed. Neither

is it the _willing_ of that action which we promise to perform; for a

promise always regards some future time, and the will has an influence

only on present actions. It follows, therefore, that since the act of

the mind, which enters into a promise, and produces its obligation,

is neither the resolving, desiring, nor willing any particular

performance, it must necessarily be the _willing_ of that _obligation_

which arises from the promise. Nor is this only a conclusion of

philosophy, but is entirely conformable to our common ways of thinking

and of expressing ourselves, when we say that we are bound by our

own consent, and that the obligation arises from our mere will and

pleasure. The only question then is, whether there be not a manifest

absurdity in supposing this act of the mind, and such an absurdity as

no man could fall into, whose ideas are not confounded with prejudice

and the fallacious use of language.

All morality depends upon our sentiments; and when any action or

quality of the mind pleases us _after a certain manner_, we say it is

virtuous; and when the neglect or non-performance of it displeases

us _after a like manner_, we say that we lie under an obligation

to perform it. A change of the obligation supposes a change of the

sentiment; and a creation of a new obligation supposes some new

sentiment to arise. But 'tis certain we can naturally no more change

our own sentiments than the motions of the heavens; nor by a single

act of our will, that is, by a promise, render any action agreeable or

disagreeable, moral or immoral, which, without that act, would have

produced contrary impressions, or have been endowed with different

qualities. It would be absurd, therefore, to will any new obligation,

that is, any new sentiment of pain or pleasure; nor is it possible

that men could naturally fall into so gross an absurdity. A promise,

therefore, is _naturally_ something altogether unintelligible, nor is

there any act of the mind belonging to it.[7]

But, _secondly_, if there was any act of the mind belonging to it, it

could not _naturally_ produce any obligation. This appears evidently

from the foregoing reasoning. A promise creates a new obligation. A new

obligation supposes new sentiments to arise. The will never creates new

sentiments. There could not naturally, therefore, arise any obligation

from a promise, even supposing the mind could fall into the absurdity

of willing that obligation.

The same truth may be proved still more evidently by that reasoning

which proved justice in general to be an artificial virtue. No action

can be required of us as our duty, unless there be implanted in

human nature some actuating passion or motive capable of producing

the action. This motive cannot be the sense of duty. A sense of

duty supposes an antecedent obligation; and where an action is not

required by any natural passion, it cannot be required by any natural

obligation; since it may be omitted without proving any defect or

imperfection in the mind and temper, and consequently without any

vice. Now, 'tis evident we have no motive leading us to the performance

of promises, distinct from a sense of duty. If we thought that promises

had no moral obligation, we never should feel any inclination to

observe them. This is not the case with the natural virtues. Though

there was no obligation to relieve the miserable, our humanity would

lead us to it; and when we omit that duty, the immorality of the

omission arises from its being a proof that we want the natural

sentiments of humanity. A father knows it to be his duty to take care

of his children, but he has also a natural inclination to it. And if

no human creature had that inclination, no one could lie under any

such obligation. But as there is naturally no inclination to observe

promises distinct from a sense of their obligation, it follows,

that fidelity is no natural virtue, and that promises have no force

antecedent to human conventions.

If any one dissent from this, he must give a regular proof of these two

propositions, viz. _that there is a peculiar act of the mind annexed

to promises_; and _that consequent to this act of the mind, there

arises an inclination to perform, distinct from a sense of duty_. I

presume that it is impossible to prove either of these two points; and

therefore I venture to conclude, that promises are human inventions,

founded on the necessities and interests of society.

In order to discover these necessities and interests, we must consider

the same qualities of human nature which we have already found to give

rise to the preceding laws of society. Men being naturally selfish, or

endowed only with a confined generosity, they are not easily induced to

perform any action for the interest of strangers, except with a view

to some reciprocal advantage, which they had no hope of obtaining

but by such a performance. Now, as it frequently happens that these

mutual performances cannot be finished at the same instant, 'tis

necessary that one party be contented to remain in uncertainty, and

depend upon the gratitude of the other for a return of kindness. But

so much corruption is there among men, that, generally speaking, this

becomes but a slender security; and as the benefactor is here supposed

to bestow his favours with a view to self-interest, this both takes

off from the obligation, and sets an example of selfishness, which

is the true mother of ingratitude. Were we, therefore, to follow the

natural course of our passions and inclinations, we should perform

but few actions for the advantage of others from disinterested views,

because we are naturally very limited in our kindness and affection;

and we should perform as few of that kind out of regard to interest,

because we cannot depend upon their gratitude. Here, then, is the

mutual commerce of good offices in a manner lost among mankind, and

every one reduced to his own skill and industry for his well-being

and subsistence. The invention of the law of nature, concerning the

_stability_ of possession, has already rendered men tolerable to each

other; that of the _transference_ of property and possession by consent

has begun to render them mutually advantageous; but still these laws

of nature, however strictly observed, are not sufficient to render

them so serviceable to each other as by nature they are fitted to

become. Though possession be _stable_, men may often reap but small

advantage from it, while they are possessed of a greater quantity of

any species of goods than they have occasion for, and at the same

time suffer by the want of others. The _transference_ of property,

which is the proper remedy for this inconvenience, cannot remedy it

entirely; because it can only take place with regard to such objects

as are _present_ and _individual_, but not to such as are _absent_ or

_general_. One cannot transfer the property of a particular house,

twenty leagues distant, because the consent cannot be attended with

delivery, which is a requisite circumstance. Neither can one transfer

the property of ten bushels of corn, or five hogsheads of wine, by the

mere expression and consent, because these are only general terms, and

have no direct relation to any particular heap of corn or barrels of

wine. Besides, the commerce of mankind is not confined to the barter

of commodities, but may extend to services and actions, which we may

exchange to our mutual interest and advantage. Your corn is ripe

to-day; mine will be so to-morrow. 'Tis profitable for us both that I

should labour with you to-day, and that you should aid me to-morrow. I

have no kindness for you, and know you have as little for me. I will

not, therefore, take any pains upon your account; and should I labour

with you upon my own account, in expectation of a return, I know I

should be disappointed, and that I should in vain depend upon your

gratitude. Here, then, I leave you to labour alone: you treat me in the

same manner. The seasons change; and both of us lose our harvests for

want of mutual confidence and security.

All this is the effect of the natural and inherent principles and

passions of human nature; and as these passions and principles are

unalterable, it may be thought that our conduct, which depends on them,

must be so too, and that 'twould be in vain, either for moralists or

politicians, to tamper with us, or attempt to change the usual course

of our actions, with a view to public interest. And, indeed, did the

success of their designs depend upon their success in correcting the

selfishness and ingratitude of men, they would never make any progress,

unless aided by Omnipotence, which is alone able to new-mould the

human mind, and change its character in such fundamental articles.

All they can pretend to is, to give a new direction to those natural

passions, and teach us that we can better satisfy our appetites in an

oblique and artificial manner, than by their headlong and impetuous

motion. Hence I learn to do a service to another, without bearing him

any real kindness; because I foresee that he will return my service,

in expectation of another of the same kind, and in order to maintain

the same correspondence of good offices with me or with others. And

accordingly, after I have served him, and he is in possession of the

advantage arising, from my action, he is induced to perform his part,

as foreseeing the consequences of his refusal.

But though this self-interested commerce of men begins to take place,

and to predominate in society, it does not entirely abolish the more

generous and noble intercourse of friendship and good offices. I may

still do services to such persons as I love, and am more particularly

acquainted with, without any prospect of advantage; and they may

make me a return in the same manner, without any view but that of

recompensing my past services. In order, therefore, to distinguish

those two different sorts of commerce, the interested and the

disinterested, there is a _certain form of words_ invented for the

former, by which we bind ourselves to the performance of any action.

This form of words constitutes what we call a _promise_, which is

the sanction of the interested commerce of mankind. When a man says

_he promises any thing_, he in effect expresses a _resolution_ of

performing it; and along with that, by making use of this _form of

words,_, subjects himself to the penalty of never being trusted again

in case of failure. A resolution is the natural act of the mind, which

promises express; but were there no more than a resolution in the case,

promises would only declare our former motives, and would not create

any new motive or obligation. They are the conventions of men, which

create a new motive, when experience has taught us that human affairs

would be conducted much more for mutual advantage, were there certain

_symbols_ or _signs_ instituted, by which we might give each other

security of our conduct in any particular incident. After these signs

are instituted, whoever uses them is immediately bound by his interest

to execute his engagements, and must never expect to be trusted any

more, if he refuse to perform what he promised.

Nor is that knowledge, which is requisite to make mankind sensible of

this interest in the _institution_ and _observance_ of promises, to be

esteemed superior to the capacity of human nature, however savage and

uncultivated. There needs but a very little practice of the world, to

make us perceive all these consequences and advantages. The shortest

experience of society discovers them to every mortal; and when each

individual perceives the same sense of interest in all his fellows, he

immediately performs his part of any contract, as being assured that

they will not be wanting in theirs. All of them, by concert, enter

into a scheme of actions, calculated for common benefit, and agree to

be true to their word; nor is there any thing requisite to form this

concert or convention, but that every one have a sense of interest

in the faithful fulfilling of engagements, and express that sense to

other members of the society. This immediately causes that interest

to operate upon them; and interest is the _first_ obligation to the

performance of promises.

Afterwards a sentiment of morals concurs with interest, and becomes

a new obligation upon mankind. This sentiment of morality, in the

performance of promises, arises from the same principles as that

in the abstinence from the property of others. _Public interest,

education_, and _the artifices of politicians_, have the same effect

in both cases. The difficulties that occur to us in supposing a moral

obligation to attend promises, we either surmount or elude. For

instance, the expression of a resolution is not commonly supposed to

be obligatory; and we cannot readily conceive how the making use of a

certain form of words should be able to cause any material difference.

Here, therefore, we _feign_ a new act of the mind, which we call the

_willing_ an obligation; and on this we suppose the morality to depend.

But we have proved already, that there is no such act of the mind, and

consequently, that promises impose no natural obligation.

To confirm this, we may subjoin some other reflections concerning

that will, which is supposed to enter into a promise, and to cause

its obligation. 'Tis evident, that the will alone is never supposed

to cause the obligation, but must be expressed by words or signs, in

order to impose a tie upon any man. The expression being once brought

in as subservient to the will, soon becomes the principal part of the

promise; nor will a man be less bound by his word, though he secretly

give a different direction to his intention, and withhold himself

both from a resolution, and from willing an obligation. But though the

expression makes on most occasions the whole of the promise, yet it

does not always so; and one who should make use of any expression of

which he knows not the meaning, and which he uses without any intention

of binding himself, would not certainly be bound by it. Nay, though he

knows its meaning, yet if he uses it in jest only, and with such signs

as show evidently he has no serious intention of binding himself, he

would not lie under any obligation of performance; but 'tis necessary

that the words be a perfect expression of the will, without any

contrary signs. Nay, even this we must not carry so far as to imagine,

that one, whom, by our quickness of understanding, we conjecture, from

certain signs, to have an intention of deceiving us, is not bound by

his expression or verbal promise, if we accept of it; but must limit

this conclusion to those cases where the signs are of a different kind

from those of deceit. All these contradictions are easily accounted

for, if the obligation of promises be merely a human invention for the

convenience of society; but will never be explained, if it be something

_real_ and _natural_, arising from any action of the mind or body.

I shall farther observe, that, since every new promise imposes a new

obligation of morality on the person who promises, and since this

new obligation arises from his will; 'tis one of the most mysterious

and incomprehensible operations that can possibly be imagined, and

may even be compared to _transubstantiation_, or _holy orders_,[8]

where a certain form of words, along with a certain intention,

changes entirely the nature of an external object, and even of a

human creature. But though these mysteries be so far alike, 'tis very

remarkable that they differ widely in other particulars, and that this

difference may be regarded as a strong proof of the difference of their

origins. As the obligation of promises is an invention for the interest

of society, 'tis warped into as many different forms as that interest

requires, and even runs into direct contradictions, rather than lose

sight of its object. But as those other monstrous doctrines are mere

priestly inventions, and have no public interest in view, they are less

disturbed in their progress by new obstacles; and it must be owned,

that, after the first absurdity, they follow more directly the current

of reason and good sense. Theologians clearly perceived, that the

external form of words, being mere sound, require an intention to make

them have any efficacy; and that this intention being once considered

as a requisite circumstance, its absence must equally prevent the

effect, whether avowed or concealed, whether sincere or deceitful.

Accordingly, they have commonly determined, that the intention of

the priest makes the sacrament, and that when he secretly withdraws

his intention, he is highly criminal in himself; but still destroys

the baptism, or communion, or holy orders. The terrible consequences

of this doctrine were not able to hinder its taking place; as the

inconvenience of a similar doctrine, with regard to promises, have

prevented that doctrine from establishing itself. Men are always more

concerned about the present life than the future; and are apt to think

the smallest evil which regards the former, more important than the

greatest which regards the latter.

We may draw the same conclusion, concerning the origin of promises,

from the force which is supposed to invalidate all contracts, and

to free us from their obligation. Such a principle is a proof

that promises have no natural obligation, and are mere artificial

contrivances for the convenience and advantage of society. If we

consider aright of the matter, force is not essentially different

from any other motive of hope or fear, which may induce us to engage

our word, and lay ourselves under any obligation. A man, dangerously

wounded, who promises a competent sum to a surgeon to cure him, would

certainly be bound to performance; though the case be not so much

different from that of one who promises a sum to a robber, as to

produce so great a difference in our sentiments of morality, if these

sentiments were not built entirely on public interest and convenience.

[7] Were morality discoverable by reason, and not by sentiment, 'twould

be still more evident that promises could make no alteration upon it.

Morality is supposed to consist in relation. Every new imposition of

morality, therefore, must arise from some new relation of objects;

and consequently the will could not produce immediately any change in

morals, but could have that effect only by producing a change upon the

objects. But as the moral obligation of a promise is the pure effect

of the will, without the least change in any part of the universe, it

follows, that promises have no natural obligation.

Should it be said, that this act of the will, being in effect a new

object, produces new relations and new duties; I would answer, that

this is a pure sophism, which may be detected by a very moderate share

of accuracy and exactness. To will a new obligation, is to will a new

relation of objects; and therefore, if this new relation of objects

were formed by the volition itself, we should, in effect, will the

volition, which is plainly absurd and impossible. The will has here

no object to which it could tend, but must return upon itself in

_infinitum_. The new obligation depends upon new relations. The new

relations depend upon a new volition. The new volition has for object a

new obligation, and consequently new relations, and consequently a new

volition; which volition, again, has in view a new obligation, relation

and volition, without any termination. 'Tis impossible, therefore, we

could ever will a new obligation; and consequently 'tis impossible the

will could ever accompany a promise, or produce a new obligation of

morality.

[8] I mean so far as holy orders are supposed to produce the _indelible

Character_. In other respects they are only a legal qualification.
