Artistic Beauty : Sir Joshua Reynolds, Ninth Discourse, 1776

The art which we profess has beauty for its object; this it is our business to discover and to express; the beauty of which we are in quest is general and intellectual; it is an idea that subsists only in the mind; the sight never beheld it, nor has the hand expressed it: it is an idea residing in the breast of the artist, which he is always laboring to impart, and which he dies at last without imparting; but which he is yet so far able to communicate, as to raise the thoughts, and extend the views of the spectator; and which, by a succession of art, may be so far diffused, that its effects may extend themselves imperceptibly into public benefits, and be among the means of bestowing on whole nations refinement of taste: which, if it does not lead directly to purity of manners, obviates, at least their greatest depravation, by disentangling the mind from appetite, and conducting the thoughts through successive stages of excellence, till that contemplation of universal rectitude and harmony which began by taste, may, as it is exalted and refined, conclude in virtue.
