T 3.2.6.4

If any one, therefore, wou'd assert, that justice is a natural virtue, and injustice a natural vice, he must assert, that abstracting from the notions of property, and right and obligation, a certain conduct and train of actions, in certain |external relations of objects, has naturally a moral beauty or deformity, and causes an original pleasure or uneasiness. Thus the restoring a man's goods to him is consider'd as virtuous, not because nature has annex'd a certain sentiment of pleasure to such a conduct, with regard to the property of others, but because she has annex'd that sentiment to such a conduct, with regard to those external objects, of which others have had the first or long possession, or which they have receiv'd by the consent of those, who have had first or long possession. If nature has given us no such sentiment, there is not, naturally, nor antecedent to human conventions, any such thing as property. Now, tho' it seems sufficiently evident, in this dry and accurate consideration of the present subject, that nature has annex'd no pleasure or sentiment of approbation to such a conduct; yet that I may leave as little room for doubt as possible, I shall subjoin a few more arguments to confirm my opinion.
