A Treatise of Human Nature

pleasures and conveniences of life. The very essence of this 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 dearly 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. It is 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 could move and act in obedience to the will; it is evident the possession of them would give pleasure and pride, but not to such a degree, as the same authority, when exerted over sensible and rational creatures, whose condition, being compared to our own, makes it seem more agreeable and honourable. Comparison is in every case a sure method of augmenting our esteem of any thing. A rich man feels the felicity of his condition better by opposing it to that of a beggar. But there is a peculiar advantage in power, by the contrast, which is, in a manner, presented to us, betwixt ourselves and the person we command. The comparison is obvious and natural: The imagination finds it in the very subject: The passage of the thought to its conception is smooth and easy. And that this circumstance has a considerable effect in augmenting its influence, will appear afterwards in examining the nature of malice and envy.
