T 2.2.5.16

This conclusion from a general view of human nature, we may confirm by particular instances, wherein the force of sympathy is very remarkable. Most kinds of beauty are deriv'd from this origin; and tho' our first object be some senseless inanimate piece of matter, 'tis seldom we rest there, and carry not our view to its influence on sensible and rational creatures. A man, who shews us any house or building, takes particular care among other things to point out the convenience of the apartments, the advantages of their situation, and the little room lost in the stairs, anti-|chambers and passages; and indeed 'tis evident, the chief part of the beauty consists in these particulars. The observation of convenience gives pleasure, since convenience is a beauty. But after what manner does it give pleasure? 'Tis certain our own interest is not in the least concern'd; and as this is a beauty of interest, not of form, so to speak, it must delight us merely by communication, and by our sympathizing with the proprietor of the lodging. We enter into his interest by the force of imagination, and feel the same satisfaction, that the objects naturally occasion in him.
