141. Farewell to color; that is to say, if the thing is to be seen distinctly, and you have only wise people to show it to; but if it is to be seen indistinctly, at a distance, color may become explanatory; and if you have simple people to show it to, color may be necessary to excite _their_ imaginations, though not to excite yours. And the art is great always by meeting its conditions in the straightest way; and if it is to please a multitude of innocent and bluntly-minded persons, must express itself in the terms that will touch them; else it is not good. And I have to trace for you through the history of the past, and possibilities of the future, the expedients used by great sculptors to obtain clearness, impressiveness, or splendor; and the manner of their appeal to the people, under various light and shadow, and with reference to different degrees of public intelligence: such investigation resolving itself again and again, as we proceed, into questions absolutely ethical; as, for instance, whether color is to be bright or dull,--that is to say, for a populace cheerful or heartless;--whether it is to be delicate or strong,--that is to say, for a populace attentive or careless; whether it is to be a background like the sky, for a procession of young men and maidens, because your populace revere life--or the shadow of the vault behind a corpse stained with drops of blackened blood, for a populace taught to worship Death. Every critical determination of rightness depends on the obedience to some ethic law, by the most rational and, therefore, simplest means. And you see how it depends most, of all things, on whether you are working for chosen persons, or for the mob; for the joy of the boudoir, or of the Borgo. And if for the mob, whether the mob of Olympia, or of St. Antoine. Phidias, showing his Jupiter for the first time, hides behind the temple door to listen, resolved afterwards "[Greek: rhythmizein to agalma pros to tois pleistois dokoun, ou gar hegeito mikran einai symboulen demou tosoutou]," and truly, as your people is, in judgment, and in multitude, so must your sculpture be, in glory. An elementary principle which has been too long out of mind. 142. I leave you to consider it, since, for some time, we shall not again be able to take up the inquiries to which it leads. But, ultimately, I do not doubt that you will rest satisfied in these following conclusions: 1. Not only sculpture, but all the other fine arts, must be for the people. 2. They must be didactic to the people, and that as their chief end. The structural arts, didactic in their manner; the graphic arts, in their matter also. 3. And chiefly the great representative and imaginative arts--that is to say, the drama and sculpture--are to teach what is noble in past history, and lovely in existing human and organic life.
