Vice, when placed on another, excites, by means of its double relations, the passion of hatred, instead of love, which for the same reason arises from virtue.
To continue the experiment, I change anew the relation of ideas, and suppose the vice to belong to myself.

What follows?
What is usual.

A subsequent change of the passion from hatred to humility.

This humility I convert into pride by a new change of the impression; and find after all that I have compleated the round, and have by these changes brought back the passion to that very situation, in which I first found it.
But to make the matter still more certain, I alter the object; and instead of vice and virtue, make the trial upon beauty and deformity, riches and poverty, power and servitude.

Each of these objects runs the circle of the passions in the same manner, by a change of their relations: And in whatever order we proceed, whether through pride, love, hatred, humility, or through humility, hatred, love, pride, the experiment is not in the least diversifyed.
