uneasy, the passion of love or hatred must arise towards the person, who is thus connected to the cause of the impression by these double relations, which I have all along requir'd. The virtue of a brother must make me love him; as his vice or infamy must excite the contrary passion. But to judge only from the situation of affairs, I shou'd not expect, that the affections wou'd rest there, and never transfuse themselves into any other impression. As there is here a person, who by means of a double relation is the object of my passion, the very same reasoning leads me to think the passion will be carry'd farther. The person has a relation of ideas to myself, according to the supposition; the passion, of which he is the object, by being either agreeable or uneasy, has a relation of impressions to pride or humility. 'Tis evident, then, that one of these passions must arise from the love or hatred.
This is the reasoning I form in conformity to my hypothesis; and am pleas'd to find upon trial that every thing answers exactly to my expectation. The virtue or vice of a son or brother not only excites love or hatred, but by a new transition, from similar causes, gives rise to pride or humility. Nothing causes greater vanity than any shining quality in our relations; as nothing mortifies us more than their vice or infamy. This exact conformity of experience to our reasoning is a convincing proof of the solidity of that hypothesis, upon which we reason.
Sixth Experiment. This evidence will be still augmented, if we reverse the experiment, and preserving still the same relations, begin only with a different passion. Suppose, that instead of the virtue or vice of a son or brother, which causes first love or hatred, and afterwards pride or humility, we place these good or bad qualities on ourselves, without any immediate connexion with the person, who is related to us: Experience shews us, that by this change of situation the whole chain is broke, and that the mind is not convey'd from one passion to another, as in the preceding instance.
