Of the beauty which the appearance of utility bestows upon all the productions of art, and of the extensive influence of this species of beauty

1 That utility is one of the principal sources of beauty has been observed by every body, who has considered with any attention what constitutes the nature of beauty. The conveniency of a house gives pleasure to the spectator as well as its regularity, and he is as much hurt when he observes the contrary defect, as when he sees the correspondent windows of different forms, or the door not placed exactly in the middle of the building. That the fitness of any system or machine to produce the end for which it was intended, bestows a certain propriety and beauty upon the whole, and renders the very thought and contemplation of it agreeable, is so very obvious that nobody has overlooked it.

2 The cause too, why utility pleases, has of late been assigned by an ingenious and agreeable philosopher, who joins the greatest depth of thought to the greatest elegance of expression, and possesses the singular and happy talent of treating the abstrusest subjects not only with the most perfect perspicuity, but with the most lively eloquence. The utility of any object, according to him, pleases the master by perpetually suggesting to him the pleasure or conveniency which it is fitted to promote.
