Some people may exclaim: "Why should the dramatist concern himself about his audience? That may be all very well for the mere journeymen of the theatre, the hacks who write to an actor-manager's order--not for the true artist! He has a soul above all such petty considerations. Art, to him, is simply self-expression. He writes to please himself, and has no thought of currying favour with an audience, whether intellectual or idiotic." To this I reply simply that to an artist of this way of thinking I have nothing to say. He has a perfect right to express himself in a whole literature of so-called plays, which may possibly be studied, and even acted, by societies organized to that laudable end. But the dramatist who declares his end to be mere self-expression stultifies himself in that very phrase. The painter may paint, the sculptor model, the lyric poet sing, simply to please himself,[5] but the drama has no meaning except in relation to an audience. It is a portrayal of life by means of a mechanism so devised as to bring it home to a considerable number of people assembled in a given place. "The public," it has been well said, "constitutes the theatre." The moment a playwright confines his work within the two or three hours' limit prescribed by Western custom for a theatrical performance, he is currying favour with an audience. That limit is imposed simply by the physical endurance and power of sustained attention that can be demanded of Western human beings assembled in a theatre. Doubtless an author could express himself more fully and more subtly if he ignored these limitations; the moment he submits to them, he renounces the pretence that mere self-expression is his aim. I know that there are haughty-souls who make no such submission, and express themselves in dramas which, so far as their proportions are concerned, might as well be epic poems or historical romances.[6] To them, I repeat, I have nothing to say. The one and only subject of the following discussions is the best method of fitting a dramatic theme for representation before an audience assembled in a theatre. But this, be it noted, does not necessarily mean "writing down" to the audience in question. It is by obeying, not by ignoring, the fundamental conditions of his craft that the dramatist may hope to lead his audience upward to the highest intellectual level which he himself can attain.
