315 pleasure is still closer and more immediate. The will seems to move easily every way, and casts a shadow or image of itself, even to that side, on which it did not settle. By means of this image the enjoyment seems to approach nearer to us, and gives us the same lively satisfaction, as if it were perfectly certain and unavoidable.

’Twill now be easy to draw this whole reasoning to a point, and to prove, that when riches produce any pride or vanity in their possessors, as they never fail to do, 'tis only by means of a double relation of impressions and ideas. The very essence of riches consists in the power of procuring the pleasures and conveniences of life. The very essence of this power consists in the probability of its exercise, and in its causing us to anticipate, by a true or false reasoning, the real existence of the pleasure. This anticipation of pleasure is, in itself, a very considerable pleasure; and as its cause is some possession or property, which we enjoy, and which is thereby related to us, we here clearly see all the parts of the foregoing system most exactly and distinctly drawn out before us.

For the same reason, that riches cause pleasure and pride, and poverty excites uneasiness and humility, power must produce the former emotions, and slavery the latter. Power or an authority over others makes us capable of satisfying all our desires; as slavery, by subjecting us to the will of others, exposes us to a thousand wants, and mortifications.

’Tis here worth observing, that the vanity of power, or shame of slavery, are much augmented by the consideration of the persons, over whom we exercise our authority, or who exercise it over us. For supposing it possible to frame statues of such an admirable mechanism, that they cou'd move and act in obedience to the will; 'tis evident the possession of them wou'd give pleasure and pride, but not to such a degree, as the same authority, when exerted over sensible and rational creatures, whose condition, being compar'd to our own, makes it seem more agreeable and honourable. Comparison is in every case a sure method of
