Inst. Lib. IL Tit. i. Sect 28.

(In the case that your grain was mixed with that of Titius,

if it was done voluntarily on the part of both of you, it is

common property, inasmuch as the individual items, i.e., the

single grains, which were the peculiar property of either of

you, were combined with your joint consent. If, however, the

mixture was accidental, or if Titius mixed it without your

consent, it does not appear that it is common property,

Inasmuch as the several components retain their original

identity. Rather, in circumstances of this sort the grain

does not become common property, any more than a herd of

cattle is regarded as common property, If Titius beasts

should have become mixed up with yours.

However, if all of the aforesaid corn is kept by either of

you, this gives rise to a suit to determine the ownership of

property, in respect of the amount of corn belonging to

each. It is in the discretion of the judge to determine

which is the corn belonging to either party.]

Where the properties of two persons are united after such a

manner as neither to admit of division nor separation, as

when one builds a house on another's ground, in that case,

the whole must belong to one of the proprietors: And here I

assert, that it naturally is conceived to belong to the

proprietor of the most considerable part. For however the

compound object may have a relation to two different

persons, and carry our view at once to both of them, yet as

the most considerable part principally engages our attention, and by the strict union draws the inferior along

it; for this reason, the whole bears a relation to the

proprietor of that part, and is regarded as his property.

The only difficulty is, what we shall be pleased to call the

most considerable part, and most attractive to the imagination.

This quality depends on several different circumstances,

which have little connexion with each other. One part of a

compound object may become more considerable than another,

either because it is more constant and durable; because it

is of greater value; because it is more obvious and remarkable; because it is of greater extent; or because its

existence is more separate and independent. It will be easy

to conceive, that, as these circumstances may be conjoined

and opposed in all the different ways, and according to all

the different degrees, which can be imagined, there will

result many cases, where the reasons on both sides are so

equally balanced, that it is impossible for us to give any

satisfactory decision. Here then is the proper business of

municipal laws, to fix what the principles of human nature

have left undetermined.

The superficies yields to the soil, says the civil law: The

writing to the paper: The canvas to the picture.

These

decisions do not well agree together, and are a proof of the

contrariety of those principles, from which they are

derived.

But of all the questions of this kind the most curious is

that, which for so many ages divided the disciples of

Proculus and Sabinus. Suppose a person shoued make a cup

from the metal of another, or a ship from his wood, and

suppose the proprietor of the metal or wood shoued demand

his goods, the question is, whether he acquires a title to

the cup or ship. Sabinus maintained the affirmative, and

asserted that the substance or matter is the foundation of

all the qualities; that it is incorruptible and immortal,

and therefore superior to the form, which is casual and

dependent. On the other hand, Proculus observed, that the

form is the most obvious and remarkable part, and that from

it bodies are denominated of this or that particular

species. To which he might have added, that the matter or

substance is in most bodies so fluctuating and uncertain,

that it is utterly impossible to trace it in all its

changes. For my part, I know not from what principles such a

controversy can be certainly determined. I shall therefore

content my self with observing, that the decision of

Trebonian seems to me pretty ingenious; that the cup belongs

to the proprietor of the metal, because it can be brought

back to its first form: But that the ship belongs to the

author of its form for a contrary reason. But however

ingenious this reason may seem, it plainly depends upon the

fancy, which by the possibility of such a reduction, finds a

closer connexion and relation betwixt a cup and the proprietor of its metal, than betwixt a ship and the

proprietor of its wood, where the substance is more fixed

and unalterable.]

The right of succession is a very natural one, from the presumed

consent of the parent or near relation, and from the general interest

of mankind, which requires, that men's possessions should pass to those,

who are dearest to them, in order to render them more industrious and

frugal. Perhaps these causes are seconded by the influence of relation,

or the association of ideas, by which we are naturally directed to

consider the son after the parent's decease, and ascribe to him a title

to his father's possessions. Those goods must become the property of

some body: But of whom is the question. Here it is evident the persons

children naturally present themselves to the mind; and being already.

connected to those possessions by means of their deceased parent, we are

apt to connect them still farther by the relation of property. Of this

there are many parallel instances.

[Footnote 20 In examining the different titles to authority

in government, we shall meet with many reasons to convince

us, that the right of succession depends, in a great measure

on the imagination. Mean while I shall rest contented with

observing one example, which belongs to the present subject.

Suppose that a person die without children, and that a

dispute arises among his relations concerning his inheritance; it is evident, that if his riches be deriv'd

partly from his father, partly from his mother, the most

natural way of determining such a dispute, is, to divide his

possessions, and assign each part to the family, from whence

it is deriv'd. Now as the person is suppos'd to have been

once the full and entire proprietor of those goods; I ask,

what is it makes us find a certain equity and natural reason

in this partition, except it be the imagination?

His

affection to these families does not depend upon his

possessions; for which reason his consent can never be

presum'd precisely for such a partition. And as to the

public interest, it seems not to be in the least concern'd

on the one side or the other.]

SECT. IV OF THE TRANSFERENCE OF PROPERTY BY CONSENT

However useful, or even necessary, the stability of possession may be to

human society, it is attended with very considerable inconveniences.

The relation of fitness or suitableness ought never to enter into

consideration, in distributing the properties of mankind; but we must

govern ourselves by rules, which are more general in their application,

and more free from doubt and uncertainty. Of this kind is present

possession upon the first establishment of society; and afterwards

occupation, prescription, accession, and succession. As these depend

very much on chance, they must frequently prove contradictory both to

men's wants and desires; and persons and possessions must often be very

ill adjusted. This is a grand inconvenience, which calls for a remedy.

To apply one directly, and allow every man to seize by violence what he

judges to be fit for him, would destroy society; and therefore the

rules of justice seek some medium betwixt a rigid stability, and this

changeable and uncertain adjustment. But there is no medium better than

that obvious one, that possession and property should always be stable,

except when the proprietor consents to bestow them on some other

person. This rule can have no ill consequence, in occasioning wars and

dissentions; since the proprietor's consent, who alone is concerned, is

taken along in the alienation: And it may serve to many good purposes

in adjusting property to persons. Different parts of the earth produce

different commodities; and not only so, but different men both are

by nature fitted for different employments, and attain to greater

perfection in any one, when they confine themselves to it alone. All

this requires a mutual exchange and commerce; for which reason the

translation of property by consent is founded on a law of nature, as

well as its stability without such a consent.

So far is determined by a plain utility and interest.

But perhaps it is

from more trivial reasons, that delivery, or a sensible transference of

the object is commonly required by civil laws, and also by the laws of

nature, according to most authors, as a requisite circumstance in the

translation of property. The property of an object, when taken for

something real, without any reference to morality, or the sentiments of

the mind, is a quality perfectly insensible, and even inconceivable; nor

can we form any distinct notion, either of its stability or translation.

This imperfection of our ideas is less sensibly felt with regard to its

stability, as it engages less our attention, and is easily past over by

the mind, without any scrupulous examination. But as the translation

of property from one person to another is a more remarkable event, the

defect of our ideas becomes more sensible on that occasion, and obliges

us to turn ourselves on every side in search of some remedy. Now as

nothing more enlivens any idea than a present impression, and a relation

betwixt that impression and the idea; it is natural for us to seek

some false light from this quarter. In order to aid the imagination in

conceiving the transference of property, we take the sensible object,

and actually transfer its possession to the person, on whom we would

bestow the property. The supposed resemblance of the actions, and the

presence of this sensible delivery, deceive the mind, and make it fancy,

that it conceives the mysterious transition of the property. And that

this explication of the matter is just, appears hence, that men have

invented a symbolical delivery, to satisfy the fancy, where the real one

is impracticable. Thus the giving the keys of a granary is understood

to be the delivery of the corn contained in it: The giving of stone

and earth represents the delivery of a mannor. This is a kind of

superstitious practice in civil laws, and in the laws of nature,

resembling the Roman catholic superstitions in religion.

As the Roman

catholics represent the inconceivable mysteries of the Christian

religion, and render them more present to the mind, by a taper, or

habit, or grimace, which is supposed to resemble them; so lawyers and

moralists have run into like inventions for the same reason, and

have endeavoured by those means to satisfy themselves concerning the

transference of property by consent.

SECT. 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, exprest 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 coued 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 nonperformance 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

it is 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 coued

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.

[Footnote 21 Were morality discoverable by reason, and not

by sentiment, it would be still more evident, that promises

cou'd make no alteration upon it. Morality is suppos'd to

consist in relation. Every new imposition of morality,

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

consequently the will coud not produce immediately any

change in morals, but cou'd 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.

Shou'd it be said, that this act of the will being in effect

a new object, produces new relations and new duties; I wou'd

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 form'd 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 cou'd 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. It is impossible,

therefore, we cou'd ever will a new obligation; and consequently it is impossible the will cou'd ever accompany

a promise, or produce a new obligation of morality.]

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 it is

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 indination,

no one coued 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, ANNEXT 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, it is 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 to 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 distinterested views; because we are naturally

very limited in our kindness and affection: And we should perform as few

of that kind, out of a 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 tomorrow. It is 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

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

must be so too, and that it would 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 aid
