A Treatise of Human Nature

by David Hume

To make this more evident, consider, that though the rules of justice are established merely by interest, their connexion with interest is somewhat singular, and is different from what may be observed on other occasions. A single act of justice is frequently contrary to public interest; and were it to stand alone, without being followed by other acts, may, in itself, be very prejudicial to society. When a man of merit, of a beneficent disposition, restores a great fortune to a miser, or a seditious bigot, he has acted justly and laudably, but the public is a real sufferer. Nor is every single act of justice, considered apart, more conducive to private interest, than to public; and it is easily conceived how a man may impoverish himself by a signal instance of integrity, and have reason to wish, that with regard to that single act, the laws of justice were for a moment suspended in the universe. But however single acts of justice may be contrary, either to public or private interest, it is certain, that the whole plan or scheme is highly conducive, or indeed absolutely requisite, both to the support of society, and the well-being of every individual. It is impossible to separate the good from the ill. Property must be stable, and must be fixed by general rules. Though in one instance the public be a sufferer, this momentary ill is amply compensated by the steady prosecution of the rule, and by the peace and order, which it establishes in society. And even every individual person must find himself a gainer, on ballancing the account; since, without justice society must immediately dissolve, and every one must fall into that savage and solitary condition, which is infinitely worse than the worst situation that can possibly be supposed in society. When therefore men have had experience enough to observe, that whatever may be the consequence of any single act of justice, performed by a single person, yet the whole system of actions, concurred in by the whole society, is infinitely advantageous to the whole, and to every part; it is not long before justice and property take place. Every member of society is sensible of this interest: Every one expresses this sense to his fellows, along with the resolution he has taken of squaring his actions by it, on condition that others will do the same. No more is requisite to induce any one of them to perform an act of justice, who has the first opportunity. This becomes an example to others. And thus justice establishes itself by a kind of convention or agreement; that is, by a sense of interest, supposed to be common to all, and where every single act is performed in expectation that others are to perform the like. Without such a convention, no one would ever have dreamed, that there was such a virtue as justice, or have been induced to conform his actions to it. Taking any single act, my justice may be pernicious in every respect; and it is only upon the supposition that others are to imitate my example, that I can be induced to embrace that virtue; since nothing but this combination can render justice advantageous, or afford me any motives to conform my self to its rules.

We come now to the second question we proposed, viz. Why we annex the idea of virtue to justice, and of vice to injustice. This question will not detain us long after the principles, which we have already established, All we can say of it at present will be dispatched in a few words: And for farther satisfaction, the reader must wait till we come to the third part of this book. The natural obligation to justice, viz, interest, has been fully explained; but as to the moral obligation, or the sentiment of right and wrong, it will first be requisite to examine the natural virtues, before we can give a full and satisfactory account of it. After men have found by experience, that their selfishness and confined generosity, acting at their liberty, totally incapacitate them for society; and at the same time have observed, that society is necessary to the satisfaction of those very passions, they are naturally induced to lay themselves under the restraint of such rules, as may render their commerce more safe and commodious. To the imposition then, and observance of these rules, both in general, and in every particular instance, they are at first induced only by a regard to interest; and this motive, on the first formation of society, is sufficiently strong and forcible. But when society has become numerous, and has encreased to a tribe or nation, this interest is more remote; nor do men so readily perceive, that disorder and confusion follow upon every breach of these rules, as in a more narrow and contracted society. But though in our own actions we may frequently lose sight of that interest, which we have in maintaining order, and may follow a lesser and more present interest, we never fail to observe the prejudice we receive, either mediately or immediately, from the injustice of others; as not being in that case either blinded by passion, or byassed by any contrary temptation. Nay when the injustice is so distant from us, as no way to affect our interest, it still displeases us; because we consider it as prejudicial to human society, and pernicious to every one that approaches the person guilty of it. We partake of their uneasiness by sympathy; and as every thing, which gives uneasiness in human actions, upon the general survey, is called Vice, and whatever produces satisfaction, in the same manner, is denominated Virtue; this is the reason why the sense of moral good and evil follows upon justice and injustice. And though this sense, in the present case, be derived only from contemplating the actions of others, yet we fail not to extend it even to our own actions. The general rule reaches beyond those instances, from which it arose; while at the same time we naturally sympathize with others in the sentiments they entertain of us. Thus self-interest is the original motive to the establishment of justice: but a sympathy with public interest is the source of the moral approbation, which attends that virtue.

Though this progress of the sentiments be natural, and even necessary, it is certain, that it is here forwarded by the artifice of politicians, who, in order to govern men more easily, and preserve peace in human society, have endeavoured to produce an esteem for justice, and an abhorrence of injustice. This, no doubt, must have its effect; but nothing can be more evident, than that the matter has been carryed too far by certain writers on morals, who seem to have employed their utmost efforts to extirpate all sense of virtue from among mankind. Any artifice of politicians may assist nature in the producing of those sentiments, which she suggests to us, and may even on some occasions, produce alone an approbation or esteem for any particular action; but it is impossible it should be the sole cause of the distinction we make betwixt vice and virtue. For if nature did not aid us in this particular, it would be in vain for politicians to talk of honourable or dishonourable, praiseworthy or blameable. These words would be perfectly unintelligible, and would no more have any idea annexed to them, than if they were of a tongue perfectly unknown to us. The utmost politicians can perform, is, to extend the natural sentiments beyond their original bounds; but still nature must furnish the materials, and give us some notion of moral distinctions.

As publick praise and blame encrease our esteem for justice; so private education and instruction contribute to the same effect. For as parents easily observe, that a man is the more useful, both to himself and others, the greater degree of probity and honour he is endowed with; and that those principles have greater force, when custom and education assist interest and reflection: For these reasons they are induced to inculcate on their children, from their earliest infancy, the principles of probity, and teach them to regard the observance of those rules, by which society is maintained, as worthy and honourable, and their violation as base and infamous. By this means the sentiments of honour may take root in their tender minds, and acquire such firmness and solidity, that they may fall little short of those principles, which are the most essential to our natures, and the most deeply radicated in our internal constitution.

What farther contributes to encrease their solidity, is the interest of our reputation, after the opinion, that a merit or demerit attends justice or injustice, is once firmly established among mankind. There is nothing, which touches us more nearly than our reputation, and nothing on which our reputation more depends than our conduct, with relation to the property of others. For this reason, every one, who has any regard to his character, or who intends to live on good terms with mankind, must fix an inviolable law to himself, never, by any temptation, to be induced to violate those principles, which are essential to a man of probity and honour.

I shall make only one observation before I leave this subject, viz, that though I assert, that in the state of nature, or that imaginary state, which preceded society, there be neither justice nor injustice, yet I assert not, that it was allowable, in such a state, to violate the property of others. I only maintain, that there was no such thing as property; and consequently could be no such thing as justice or injustice. I shall have occasion to make a similar reflection with regard to promises, when I come to treat of them; and I hope this reflection, when duly weighed, will suffice to remove all odium from the foregoing opinions, with regard to justice and injustice.

SECT. III OF THE RULES WHICH DETERMINE PROPERTY

Though the establishment of the rule, concerning the stability of possession, be not only useful, but even absolutely necessary to human society, it can never serve to any purpose, while it remains in such general terms. Some method must be shewn, by which we may distinguish what particular goods are to be assigned to each particular person, while the rest of mankind are excluded from their possession and enjoyment. Our next business, then, must be to discover the reasons which modify this general rule, and fit it to the common use and practice of the world.

It is obvious, that those reasons are not derived from any utility or advantage, which either the particular person or the public may reap from his enjoyment of any particular goods, beyond what would result from the possession of them by any other person. Twere better, no doubt, that every one were possessed of what is most suitable to him, and proper for his use: But besides, that this relation of fitness may be common to several at once, it is liable to so many controversies, and men are so partial and passionate in judging of these controversies, that such a loose and uncertain rule would be absolutely incompatible with the peace of human society. The convention concerning the stability of possession is entered into, in order to cut off all occasions of discord and contention; and this end would never be attained, were we allowed to apply this rule differently in every particular case, according to every particular utility, which might be discovered in such an application. Justice, in her decisions, never regards the fitness or unfitness of objects to particular persons, but conducts herself by more extensive views. Whether a man be generous, or a miser, he is equally well received by her, and obtains with the same facility a decision in his favours, even for what is entirely useless to him.

It follows therefore, that the general rule, that possession must be stable, is not applied by particular judgments, but by other general rules, which must extend to the whole society, and be inflexible either by spite or favour. To illustrate this, I propose the following instance. I first consider men in their savage and solitary condition; and suppose, that being sensible of the misery of that state, and foreseeing the advantages that would result from society, they seek each other's company, and make an offer of mutual protection and assistance. I also suppose, that they are endowed with such sagacity as immediately to perceive, that the chief impediment to this project of society and partnership lies in the avidity and selfishness of their natural temper; to remedy which, they enter into a convention for the stability of possession, and for mutual restraint and forbearance. I am sensible, that this method of proceeding is not altogether natural; but besides that I here only suppose those reflections to be formed at once, which in fact arise insensibly and by degrees; besides this, I say, it is very possible, that several persons, being by different accidents separated from the societies, to which they formerly belonged, may be obliged to form a new society among themselves; in which case they are entirely in the situation above-mentioned.
