No one who has followed the history of the theater for the past quarter of a century can fail to acknowledge that these social plays of Ibsen have exerted a direct, an immediate and a powerful influence on the development of the contemporary drama. It is easy to dislike them; indeed, it is not hard even to detest them; but it is impossible to deny that they have been a stimulus to the dramatists of every modern language--and not least to playwrights of various nationalities wholly out of sympathy with Ibsen's own philosophy. The fascination of these social dramas may be charmless, as Mr. Henry James once asserted; but there is no gainsaying the fascination itself. As M. Maeterlinck has declared, Ibsen is "perhaps the only writer for the stage who has caught sight of and set in motion, a new, tho still disagreeable, poetry, which he has succeeded in investing with a kind of savage, gloomy beauty"; and M. Maeterlinck then questions whether this beauty is not too savage and too gloomy to become general or definitive. But, none the less, it is at least beauty, a quality long banished from the stage, when Ibsen showed how it might be made to bloom there again. Nor is there any dispute as to the variety and the veracity of the characters that people these studies from life. Indeed, as Mr. Archer once pointed out, "habitually and instinctively men pay to Ibsen the compliment (so often paid to Shakspere) of discussing certain of his female characters as tho they were real women, living lives apart from the poet's creative intelligence." And in yet another way is Ibsen treated like Shakspere, in that there is superabundant discussion not only of his characters, male and female, but also of his moral aim, of his sociological intention, of his philosophy of life, while very little attention is paid to his dramaturgic craftsmanship, to his command of structural beauty, to his surpassing skill in the difficult art of the play-maker. Yet Shakspere and Ibsen are professional playwrights, both of them, each making plays adjusted exactly to the conditions of the theater of his own time; and if the author of 'Othello' can prove himself (when the spirit moves him) to be a master-technician, so also can the author of 'Ghosts.'
