line of ancestors. The imagination runs not along them with facility, nor is able to transfer the honour and credit of the ancestors to their posterity of the same name and family so readily, as when the transition is conformable to the general rules, and passes from father to son, or from brother to brother. [4] Part II. Sect, 2. SECT. X OF PROPERTY AND RICHES But the relation, which is esteemed the closest, and which of all others produces most commonly the passion of pride, is that of property. This relation it will be impossible for me fully to explain before I come to treat of justice and the other moral virtues. It is sufficient to observe on this occasion, that property may be defined, such a relation betwixt a person and an object as permits him, but forbids any other, the free use and possession of it, without violating the laws of justice and moral equity. If justice, therefore, be a virtue, which has a natural and original influence on the human mind, property may be looked upon as a particular species of causation; whether we consider the liberty it gives the proprietor to operate as he please upon the object or the advantages, which he reaps from it. It is the same case, if justice, according to the system of certain philosophers, should be esteemed an artificial and not a natural virtue. For then honour, and custom, and civil laws supply the place of natural conscience, and produce, in some degree, the same effects. This in the mean time is certain, that the mention of the property naturally carries our thought to the proprietor, and of the proprietor to the property; which being a proof of a perfect relation of ideas is all that is requisite to our present purpose. A relation of ideas, joined to that of impressions, always produces a transition of affections; and therefore, whenever any pleasure or pain arises from an object, connected with us by property. we may be certain, that either pride or humility must arise from this conjunction of relations; if the foregoing system be solid and satisfactory. And whether it be so or not, we may soon satisfy ourselves by the most cursory view of human life.
