To invent anything is difficult, and in proportion to its merits praiseworthy. To cavil at that which has been devised, to point with the finger of scorn at its imperfections, to "run it down," is only too easy a pastime. Oscar Wilde was before all an inventor. Whatever he touched he endowed with the gracious gift of style that bore the stamp of his own individual genius. He originated a new treatment for ancient themes. For there is no such thing as an absolutely new "plot." Every play that has been written is founded on doings, dealings, incidents that have happened over and over again. Love, licit or illicit, the mainspring of all drama, is the same to-day as it was yesterday, and will be for ever and ever in this world. One man and one woman, or one woman and two men, or again, as a pleasant variant, two women and one man. Such are the eternal puppets that play the game of Love upon the Stage of Life; the unconscious victims of the sentiment which sometimes makes for tragedy. They are always with us, placed in the same situations, and extricating themselves (or otherwise) in the same old way. So that when a new playwright is condemned by the critics as a furbisher-up of well-known _clichés_ he is hardly treated. He cannot help himself. He must tread the familiar paths, _faute de mieux_. And the public, with its big human heart and unquestioning traditions, knows this, and is satisfied therewith. Nothing really pleases people so much as to tell them something they already know. What an accomplished dramatist can do is to rehabilitate his characters by the power of his own personality, and by felicitous treatment invest his action with fresh interest. And this is what Oscar Wilde effected in stagecraft. He vitalised it.
