A Treatise of Human Nature

by David Hume

It is evident, that when we praise any actions, we regard only the motives that produced them, and consider the actions as signs or indications of certain principles in the mind and temper. The external performance has no merit. We must look within to find the moral quality. This we cannot do directly; and therefore fix our attention on actions, as on external signs. But these actions are still considered as signs; and the ultimate object of our praise and approbation is the motive, that produced them.

After the same manner, when we require any action, or blame a person for not performing it, we always suppose, that one in that situation should be influenced by the proper motive of that action, and we esteem it vicious in him to be regardless of it. If we find, upon enquiry, that the virtuous motive was still powerful over his breast, though checked in its operation by some circumstances unknown to us, we retract our blame, and have the same esteem for him, as if he had actually performed the action, which we require of him.

It appears, therefore, that all virtuous actions derive their merit only from virtuous motives, and are considered merely as signs of those motives. From this principle I conclude, that the first virtuous motive, which bestows a merit on any action, can never be a regard to the virtue of that action, but must be some other natural motive or principle. To suppose, that the mere regard to the virtue of the action may be the first motive, which produced the action, and rendered it virtuous, is to reason in a circle. Before we can have such a regard, the action must be really virtuous; and this virtue must be derived from some virtuous motive: And consequently the virtuous motive must be different from the regard to the virtue of the action. A virtuous motive is requisite to render an action virtuous. An action must be virtuous, before we can have a regard to its virtue. Some virtuous motive, therefore, must be antecedent to that regard.

Nor is this merely a metaphysical subtilty; but enters into all our reasonings in common life, though perhaps we may not be able to place it in such distinct philosophical terms. We blame a father for neglecting his child. Why? because it shews a want of natural affection, which is the duty of every parent. Were not natural affection a duty, the care of children could not be a duty; and it were impossible we could have the duty in our eye in the attention we give to our offspring. In this case, therefore, all men suppose a motive to the action distinct from a sense of duty.

Here is a man, that does many benevolent actions; relieves the distressed, comforts the afflicted, and extends his bounty even to the greatest strangers. No character can be more amiable and virtuous. We regard these actions as proofs of the greatest humanity. This humanity bestows a merit on the actions. A regard to this merit is, therefore, a secondary consideration, and derived from the antecedent principle of humanity, which is meritorious and laudable.

In short, it may be established as an undoubted maxim, THAT NO ACTION CAN BE VIRTUOUS, OR MORALLY GOOD, UNLESS THERE BE IN HUMAN NATURE SOME MOTIVE TO PRODUCE IT, DISTINCT FROM THE SENSE OF ITS MORALITY.

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 it is usual, in this case, as in all others, to fix our attention on the signs, and neglect, in some measure, the thing signifyed. 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 villainy 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 it is 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 it is impossible, that the virtuous motive and the regard to the virtue can be the same.

It is 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 it is 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 publick 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 shewn 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.
