The Stage Society has shown the courage of its opinions by giving an unlicensed play, "Mrs. Warren's Profession," one of the "unpleasant plays" of Mr. George Bernard Shaw, at the theatre of the New Lyric Club. It was well acted, with the exception of two of the characters, and the part of Mrs. Warren was played by Miss Fanny Brough, one of the cleverest actresses on the English stage, with remarkable ability. The action was a little cramped by the smallness of the stage, but, for all that, the play was seen under quite fair conditions, conditions under which it could be judged as an acting play and as a work of art. It is brilliantly clever, with a close, detective cleverness, all made up of merciless logic and unanswerable common sense. The principal characters are well drawn, the scenes are constructed with a great deal of theatrical skill, the dialogue is telling, the interest is held throughout. To say that the characters, without exception, are ugly in their vice and ugly in their virtue; that they all have, men and women, something of the cad in them; that their language is the language of vulgar persons, is, perhaps, only to say that Mr. Shaw has chosen, for artistic reasons, to represent such people just as they are. But there is something more to be said. "Mrs. Warren's Profession" is not a representation of life; it is a discussion about life. Now, discussion on the stage may be interesting. Why not? Discussion is the most interesting thing in the world, off the stage; it is the only thing that makes an hour pass vividly in society; but when discussion ends art has not begun. It is interesting to see a sculptor handling bits of clay, sticking them on here, scraping them off there; but that is only the interest of a process. When he has finished I will consider whether his figure is well or ill done; until he has finished I can have no opinion about it. It is the same thing with discussion on the stage. The subject of Mr. Shaw's discussion is what is called a "nasty" one. That is neither here nor there, though it may be pointed out that there is no essential difference between the problem that he discusses and the problem that is at the root of "The Second Mrs. Tanqueray."
