A TREATISE OF HUMAN NATURE.

unintelligible and sophistical. For one in that situation wou'd 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 plac'd in the motive, from which the external action is deriv'd. 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 shou'd we say, that a concern for our private interest or reputation is the legitimate motive to all honest actions; it wou'd 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 shou'd it be affirm'd, 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; shou'd this be said, I wou'd propose the three following considerations, as worthy of our attention. First, public interest is not naturally attach'd 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
