479 In short, it may be establish'd 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 pleas'd to perform grateful actions, and thinks he has, by that means, fulfill'd his duty. Actions are at first only consider'd 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 signify'd. But tho', 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 restor'd 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 civiliz'd state, and when train'd up according to a certain discipline and education. But in his rude and more natural condition, if you are pleas'd to call such a condition natural, this answer wou'd be rejected as perfectly
