But may not the sense of morality or duty produce an action, without any other motive? I answer, it may; but this is no objection to the present doctrine. When any virtuous motive or principle is common in human nature, a person who feels his heart devoid of that motive, may hate himself upon that account, and may perform the action without the motive, from a certain sense of duty, in order to acquire, by practice, that virtuous principle, or at least to disguise to himself, as much as possible, his want of it. A man that really feels no gratitude in his temper, is still pleased to perform grateful actions, and thinks he has, by that means, fulfilled his duty. Actions are at first only considered as signs of motives: but 'tis usual, in this case, as in all others, to fix our attention on the signs, and neglect, in some measure, the thing signified. But though, on some occasions, a person may perform an action merely out of regard to its moral obligation, yet still this supposes in human nature some distinct principles, which are capable of producing the action, and whose moral beauty renders the action meritorious.

Now, to apply all this to the present case; I suppose a person to have lent me a sum of money, on condition that it be restored in a few days; and also suppose, that after the expiration of the term agreed on, he demands the sum: I ask, What reason or motive have I to restore the money? It will perhaps be said, that my regard to justice, and abhorrence of villany and knavery, are sufficient reasons for me, if I have the least grain of honesty, or sense of duty and obligation. And this answer, no doubt, is just and satisfactory to man in his civilized state, and when trained up according to a certain discipline and education. But in his rude and more natural condition, if you are pleased to call such a condition natural, this answer would be rejected as perfectly unintelligible and sophistical. For one in that situation would immediately ask you, Wherein consists this honesty and justice, which you find in restoring a loan, and abstaining from the property of others? It does not surely lie in the external action. It must, therefore, be placed in the motive from which the external action is derived. This motive can never be a regard to the honesty of the action. For 'tis a plain fallacy to say, that a virtuous motive is requisite to render an action honest, and, at the same time, that a regard to the honesty is the motive of the action. We can never have a regard to the virtue of an action, unless the action be antecedently virtuous. No action can be virtuous, but so far as it proceeds from a virtuous motive. A virtuous motive, therefore, must precede the regard to the virtue; and 'tis impossible that the virtuous motive and the regard to the virtue can be the same.

'Tis requisite, then, to find some motive to acts of justice and honesty, distinct from our regard to the honesty; and in this lies the great difficulty. For should we say, that a concern for our private interest or reputation, is the legitimate motive to all honest actions: it would follow, that wherever that concern ceases, honesty can no longer have place. But 'tis certain that self-love, when it acts at its liberty, instead of engaging us to honest actions, is the source of all injustice and violence; nor can a man ever correct those vices, without correcting and restraining the natural movements of that appetite.

But should it be affirmed, that the reason or motive of such actions is the regard to public interest, to which nothing is more contrary than examples of injustice and dishonesty; should this be said, I would propose the three following considerations as worthy of our attention. First, Public interest is not naturally attached to the observation of the rules of justice; but is only connected with it, after an artificial convention for the establishment of these rules, as shall be shown more at large hereafter. Secondly, If we suppose that the loan was secret, and that it is necessary for the interest of the person, that the money be restored in the same manner (as when the lender would conceal his riches), in that case the example ceases, and the public is no longer interested in the actions of the borrower; though I suppose there is no moralist who will affirm that the duty and obligation ceases. Thirdly, Experience sufficiently proves that men, in the ordinary conduct of life, look not so far as the public interest, when they pay their creditors, perform their promises, and abstain from theft, and robbery, and injustice of every kind. That is a motive too remote and too sublime to affect the generality of mankind, and operate with any force in actions so contrary to private interest as are frequently those of justice and common honesty.

In general, it may be affirmed, that there is no such passion in human minds as the love of mankind, merely as such, independent of personal qualities, of services, or of relation to ourself. 'Tis true, there is no human, and indeed no sensible creature, whose happiness or misery does not, in some measure, affect us, when brought near us, and represented in lively colours: but this proceeds merely from sympathy, and is no proof of such an universal affection to mankind, since this concern extends itself beyond our own species. An affection betwixt the sexes is a passion evidently implanted in human nature; and this passion not only appears in its peculiar symptoms, but also in inflaming every other principle of affection, and raising a stronger love from beauty, wit, kindness, than what would otherwise flow from them. Were there an universal love among all human creatures, it would appear after the same manner. Any degree of a good quality would cause a stronger affection than the same degree of a bad quality would cause hatred; contrary to what we find by experience. Men's tempers are different, and some have a propensity to the tender, and others to the rougher affections: but in the main, we may affirm, that man in general, or human nature, is nothing but the object both of love and hatred, and requires some other cause, which, by a double relation of impressions and ideas, may excite these passions. In vain would we endeavour to elude this hypothesis. There are no phenomena that point out any such kind affection to men, independent of their merit, and every other circumstance. We love company in general; but 'tis as we love any other amusement. An Englishman in Italy is a friend; a European in China; and perhaps a man would be beloved as such, were we to meet him in the moon. But this proceeds only from the relation to ourselves; which in these cases gathers force by being confined to a few persons.

If public benevolence, therefore, or a regard to the interests of mankind, cannot be the original motive to justice, much less can private benevolence, or a regard to the interests of the party concerned, be this motive. For what if he be my enemy, and has given me just cause to hate him? What if he be a vicious man, and deserves the hatred of all mankind? What if he be a miser, and can make no use of what I would deprive him of? What if he be a profligate debauchee, and would rather receive harm than benefit from large possessions? What if I be in necessity, and have urgent motives to acquire something to my family? In all these cases, the original motive to justice would fail; and consequently the justice itself, and along with it all property, right, and obligation.

A rich man lies under a moral obligation to communicate to those in necessity a share of his superfluities. Were private benevolence the original motive to justice, a man would not be obliged to leave others in the possession of more than he is obliged to give them. At least, the difference would be very inconsiderable. Men generally fix their affections more on what they are possessed of, than on what they never enjoyed: for this reason, it would be greater cruelty to dispossess a man of any thing, than not to give it him. But who will assert, that this is the only foundation of justice?

Besides, we must consider, that the chief reason why men attach themselves so much to their possessions, is, that they consider them as their property, and as secured to them inviolably by the laws of society. But this is a secondary consideration, and dependent on the preceding notions of justice and property.

A man's property is supposed to be fenced against every mortal, in every possible case. But private benevolence is, and ought to be, weaker in some persons than in others; and in many, or indeed in most persons, must absolutely fail. Private benevolence, therefore, is not the original motive of justice.

From all this it follows, that we have no real or universal motive for observing the laws of equity, but the very equity and merit of that observance; and as no action can be equitable or meritorious, where it cannot arise from some separate motive, there is here an evident sophistry and reasoning in a circle. Unless, therefore, we will allow that nature has established a sophistry, and rendered it necessary and unavoidable, we must allow, that the sense of justice and injustice is not derived from nature, but arises artificially, though necessarily, from education, and human conventions.
