A moralist he must be, if his work is to have any far-reaching significance, any final value. Morality is not something a poet can put into his work deliberately; but it can be left out only at the poet's peril, since few works of art are likely to be worth while if they are ethically empty. Ibsen's inspiration is too rich for it to be void of moral purport, even tho the playwright may not have intended all that we read into his work. There is a moral in 'Ghosts' as there is in 'OEdipus,' in the 'Scarlet Letter,' and in 'Anna Karenina,'--a moral, austere and dispassionate. It contains much that is unpleasant and even painful, but--to quote Arnold's praise of 'Anna Karenina'--nothing "of a nature to trouble the senses or to please those who wish their senses troubled." Ibsen's play, like the tragedy of Sophocles, like the severe stories of Hawthorne and Tolstoi, is not spoon-meat for babes; it is not for young men and maidens; but as Goethe asked nearly a century ago, "What business have our young girls at the theater? They do not belong to it;--they belong to the convent; and the theater is only for men and women who know something of human affairs." It is for these men and these women that Ibsen, with stern self-control, has written his social dramas, that he may force them to look into matters they are willing enough to ignore and to front the facts of life, ugly as these may be. More than once in the course of this essay has there been occasion to evoke the names of Sophocles, of Shakspere and of Moliere, the supreme masters of the dramatic art. To venture upon any comparison with them is to measure Ibsen by the loftiest standard. In his technic alone can he withstand the comparison, for he is the latest and he has profited by all the experiments and achievements of the strong men who came before him; in mere craftsmanship he is beyond question the foremost of all the moderns. It must be said also that in his intellectual honesty, in his respect for the immitigable laws of character, he rarely falls short. He lacks the clear serenity of Sophocles, the depth and the breadth of the myriad-minded Shakspere, the humorous toleration of Moliere. The great Greek, the great Englishman, and the great Frenchman, are, all of them, liberal and sane and wholesome, whatever their subject-matter may be; and here it is that the Scandinavian is felt to be inferior. There are few of his social dramas in which we cannot find more than a hint of abnormal eccentricity or of morbid perversity; and this is the reason why the most of them fail to attain the dignity of true and lofty tragedy.
