The remedy, then, is not derived from nature, but from artifice; or more properly speaking, nature provides a remedy in the judgment and understanding, for what is irregular and incommodious in the affections. For when men, from their early education in society, have become sensible of the infinite advantages that result from it, and have besides acquired a new affection to company and conversation; and when they have observed, that the principal disturbance in society arises from those goods, which we call external, and from their looseness and easy transition from one person to another; they must seek for a remedy by putting these goods, as far as possible, on the same footing with the fixed and constant advantages of the mind and body. This can be done after no other manner, than by a convention entered into by all the members of the society to bestow stability on the possession of those external goods, and leave everyone in the peaceable enjoyment of what he may acquire by his fortune and industry. By this means, everyone knows what he may safely possess; and the passions ale restrained in their partial and contradictory motions. Nor is such a restraint contrary to these passions; for if so, it could never be entered into, nor maintained; but it is only contrary to their heedless and impetuous movement. Instead of departing from our own interest, or from that of our nearest friends, by abstaining from the possessions of others, we cannot better consult both these interests, than by such a convention; because it is by that means we maintain society, which is so necessary to their well-being and subsistence, as well as to our own.
This convention is not of the nature of a promise: For even promises themselves, as we shall see afterwards, arise from human conventions. It is only a general sense of common interest; which sense all the members of the society express to one another, and which induces them to regulate their conduct by certain rules. I observe, that it will be for my interest to leave another in the possession of his goods, provided he will act in the same manner with regard to me. He is sensible of a like interest in the regulation of his conduct. When this common sense of interest is mutually expressed, and is known to both, it produces a suitable resolution and behaviour. And this may properly enough be called a convention or agreement betwixt us, though without the interposition of a promise; since the actions of each of us have a reference to those of the other, and are performed upon the supposition, that something is to be performed on the other part. Two men, who pull the oars of a boat, do it by an agreement or convention, though they have never given promises to each other. Nor is the rule concerning the stability of possession the less derived from human conventions, that it arises gradually, and acquires force by a slow progression, and by our repeated experience of the inconveniences of transgressing it. On the contrary, this experience assures us still more, that the sense of interest has become common to all our fellows, and gives us a confidence of the future regularity of their conduct: And it is only on the expectation of this, that our moderation and abstinence are founded. In like manner are languages gradually established by human conventions without any promise. In like manner do gold and silver become the common measures of exchange, and are esteemed sufficient payment for what is of a hundred times their value.
After this convention, concerning abstinence from the possessions of others, is entered into, and everyone has acquired a stability in his possessions, there immediately arise the ideas of justice and injustice; as also those of property, right, and obligation. The latter are altogether unintelligible without first understanding the former. Our property is nothing but those goods, whose constant possession is established by the laws of society; that is, by the laws of justice. Those, therefore, who make use of the words property, or right, or obligation, before they have explained the origin of justice, or even make use of them in that explication, are guilty of a very gross fallacy, and can never reason upon any solid foundation. A man’s property is some object related to him. This relation is not natural, but moral, and founded on justice. It is very preposterous, therefore, to imagine, that we can have any idea of property, without fully comprehending the nature of justice, and showing its origin in the artifice and contrivance of man. The origin of justice explains that of property. The same artifice gives rise to both. As our first and most natural sentiment of morals is founded on the nature of our passions, and gives the preference to ourselves and friends, above strangers; it is impossible there can be naturally any such thing as a fixed right or property, while the opposite passions of men impel them in contrary directions, and are not restrained by any convention or agreement.
No one can doubt, that the convention for the distinction of property, and for the stability of possession, is of all circumstances the most necessary to the establishment of human society, and that after the agreement for the fixing and observing of this rule, there remains little or nothing to be done towards settling a perfect
