A Treatise of Human Nature

by David Hume

Of all the animals, with which this globe is peopled, there is none towards whom nature seems, at first sight, to have exercised more cruelty than towards man, in the numberless wants and necessities, with which she has loaded him, and in the slender means, which she affords to the relieving these necessities. In other creatures these two particulars generally compensate each other. If we consider the lion as a voracious and carnivorous animal, we shall easily discover him to be very necessitous; but if we turn our eye to his make and temper, his agility, his courage, his arms, and his force, we shall find, that his advantages hold proportion with his wants. The sheep and ox are deprived of all these advantages; but their appetites are moderate, and their food is of easy purchase. In man alone, this unnatural conjunction of infirmity, and of necessity, may be observed in its greatest perfection. Not only the food, which is required for his sustenance, flies his search and approach, or at least requires his labour to be produced, but he must be possessed of cloaths and lodging, to defend him against the injuries of the weather; though to consider him only in himself, he is provided neither with arms, nor force, nor other natural abilities, which are in any degree answerable to so many necessities.

It is by society alone he is able to supply his defects, and raise himself up to an equality with his fellow-creatures, and even acquire a superiority above them. By society all his infirmities are compensated; and though in that situation his wants multiply every moment upon him, yet his abilities are still more augmented, and leave him in every respect more satisfied and happy, than it is possible for him, in his savage and solitary condition, ever to become. When every individual person labours apart, and only for himself, his force is too small to execute any considerable work; his labour being employed in supplying all his different necessities, he never attains a perfection in any particular art; and as his force and success are not at all times equal, the least failure in either of these particulars must be attended with inevitable ruin and misery. Society provides a remedy for these three inconveniences. By the conjunction of forces, our power is augmented: By the partition of employments, our ability encreases: And by mutual succour we are less exposed to fortune and accidents. It is by this additional force, ability, and security, that society becomes advantageous.

But in order to form society, it is requisite not only that it be advantageous, but also that men be sensible of these advantages; and it is impossible, in their wild uncultivated state, that by study and reflection alone, they should ever be able to attain this knowledge. Most fortunately, therefore, there is conjoined to those necessities, whose remedies are remote and obscure, another necessity, which having a present and more obvious remedy, may justly be regarded as the first and original principle of human society. This necessity is no other than that natural appetite betwixt the sexes, which unites them together, and preserves their union, till a new tye takes place in their concern for their common offspring. This new concern becomes also a principle of union betwixt the parents and offspring, and forms a more numerous society; where the parents govern by the advantage of their superior strength and wisdom, and at the same time are restrained in the exercise of their authority by that natural affection, which they bear their children. In a little time, custom and habit operating on the tender minds of the children, makes them sensible of the advantages, which they may reap from society, as well as fashions them by degrees for it, by rubbing off those rough corners and untoward affections, which prevent their coalition.

For it must be confest, that however the circumstances of human nature may render an union necessary, and however those passions of lust and natural affection may seem to render it unavoidable; yet there are other particulars in our natural temper, and in our outward circumstances, which are very incommodious, and are even contrary to the requisite conjunction. Among the former, we may justly esteem our selfishness to be the most considerable. I am sensible, that generally speaking, the representations of this quality have been carried much too far; and that the descriptions, which certain philosophers delight so much to form of mankind in this particular, are as wide of nature as any accounts of monsters, which we meet with in fables and romances. So far from thinking, that men have no affection for any thing beyond themselves, I am of opinion, that though it be rare to meet with one, who loves any single person better than himself; yet it is as rare to meet with one, in whom all the kind affections, taken together, do not overbalance all the selfish. Consult common experience: Do you not see, that though the whole expence of the family be generally under the direction of the master of it, yet there are few that do not bestow the largest part of their fortunes on the pleasures of their wives, and the education of their children, reserving the smallest portion for their own proper use and entertainment. This is what we may observe concerning such as have those endearing ties; and may presume, that the case would be the same with others, were they placed in a like situation.

But though this generosity must be acknowledged to the honour of human nature, we may at the same time remark, that so noble an affection, instead of fitting men for large societies, is almost as contrary to them, as the most narrow selfishness. For while each person loves himself better than any other single person, and in his love to others bears the greatest affection to his relations and acquaintance, this must necessarily produce an oppositon of passions, and a consequent opposition of actions; which cannot but be dangerous to the new-established union.

It is however worth while to remark, that this contrariety of passions would be attended with but small danger, did it not concur with a peculiarity in our outward circumstances, which affords it an opportunity of exerting itself. There are different species of goods, which we are possessed of; the internal satisfaction of our minds, the external advantages of our body, and the enjoyment of such possessions as we have acquired by our industry and good fortune. We are perfectly secure in the enjoyment of the first. The second may be ravished from us, but can be of no advantage to him who deprives us of them. The last only are both exposed to the violence of others, and may be transferred without suffering any loss or alteration; while at the same time, there is not a sufficient quantity of them to supply every one's desires and necessities. As the improvement, therefore, of these goods is the chief advantage of society, so the instability of their possession, along with their scarcity, is the chief impediment.

In vain should we expect to find, in uncultivated nature, a remedy to this inconvenience; or hope for any inartificial principle of the human mind, which might controul those partial affections, and make us overcome the temptations arising from our circumstances. The idea of justice can never serve to this purpose, or be taken for a natural principle, capable of inspiring men with an equitable conduct towards each other. That virtue, as it is now understood, would never have been dreamed of among rude and savage men. For the notion of injury or injustice implies an immorality or vice committed against some other person: And as every immorality is derived from some defect or unsoundness of the passions, and as this defect must be judged of, in a great measure, from the ordinary course of nature in the constitution of the mind; it will be easy to know, whether we be guilty of any immorality, with regard to others, by considering the natural, and usual force of those several affections, which are directed towards them. Now it appears, that in the original frame of our mind, our strongest attention is confined to ourselves; our next is extended to our relations and acquaintance; and it is only the weakest which reaches to strangers and indifferent persons. This partiality, then, and unequal affection, must not only have an influence on our behaviour and conduct in society, but even on our ideas of vice and virtue; so as to make us regard any remarkable transgression of such a degree of partiality, either by too great an enlargement, or contraction of the affections, as vicious and immoral. This we may observe in our common judgments concerning actions, where we blame a person, who either centers all his affections in his family, or is so regardless of them, as, in any opposition of interest, to give the preference to a stranger, or mere chance acquaintance. From all which it follows, that our natural uncultivated ideas of morality, instead of providing a remedy for the partiality of our affections, do rather conform themselves to that partiality, and give it an additional force and influence.

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 every one in the peaceable enjoyment of what he may acquire by his fortune and industry. By this means, every one 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 every one 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 shewing 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.
