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.
