The observation of convenience gives pleasure, since convenience is a beauty.

But after what manner does it give pleasure?
It is certain our own interest is not in the least concerned; 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.
This observation extends to tables, chairs, scritoires, chimneys, coaches, sadles, ploughs, and indeed to every work of art; it being an universal rule, that their beauty is chiefly derived from their utility, and from their fitness for that purpose, to which they are destined.
But this is an advantage, that concerns only the owner, nor is there any thing but sympathy, which can interest the spectator.
It is evident, that nothing renders a field more agreeable than its fertility, and that scarce any advantages of ornament or situation will be able to equal this beauty.

It is the same case with particular trees and plants, as with the field on which they grow.

I know not but a plain, overgrown with furze and broom, may be, in itself, as beautiful as a hill covered with vines or olive-trees; though it will never appear so to one, who is acquainted with the value of each.
