If any one, therefore, would assert, that justice is a natural virtue, and injustice a natural vice, he must assert, that abstracting from the nations 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 considered as virtuous, not because nature has annexed a certain sentiment of pleasure to such a conduct, with regard to the property of others, but because she has annexed 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 received 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, though it seems sufficiently evident, in this dry and accurate consideration of the present subject, that nature has annexed 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.
First, If nature had given us a pleasure of this kind, it would have been as evident and discernible as on every other occasion; nor should we have found any difficulty to perceive, that the consideration of such actions, in such a situation, gives a certain pleasure and sentiment of approbation. We should not have been obliged to have recourse to notions of property in the definition of justice, and at the same time make use of the notions of justice in the definition of property. This deceitful method of reasoning is a plain proof, that there are contained in the subject some obscurities and difficulties, which we are not able to surmount, and which we desire to evade by this artifice.
