Several traits emerge from this welter of cross-purposes and action. Individualism is a leading motive from the first to the last play; a strong sense of moral responsibility--an oppressive sense, one is tempted to add--is blended with a curious flavour of Calvinism, in which are traces of predestination. A more singular equipment for a modern dramatist is barely conceivable. Soon we discover that Ibsen is playing with the antique dramatic counters under another name. Free-will and determinism--what are these but the very breath of classic tragedy! In one of his rare moments of expansion he said: "Many things and much upon which my later work has turned--the contradiction between endowment and desire, between capacity and will, at once the entire tragedy and comedy of mankind--may here be dimly discerned." Moral responsibility evaded is a favourite theme of his. No Furies of the Greek drama pursued their victims with such relentless vengeance as pursues the unhappy wretches of Ibsen. In Ghosts, the old scriptural wisdom concerning the sins of parents is vividly expounded, though the heredity doctrine is sadly overworked. As in other plays of his, there were false meanings read into the interpretation; the realism of Ghosts is negligible; the symbol looms large in every scene. Search Ibsen throughout and it will be found that his subject-matter is fundamentally the same as that of all great masters of tragedy. It is his novel manner of presentation, his transposition of themes hitherto treated epically, to the narrow, unheroic scale of middle-class family life that blinded critics to his true significance. This tuning down of the heroic, this reversal of the old æsthetic order extorted bitter remonstrances. If we kill the ideal in art and life, what have we left? was the cry. But Ibsen attacks false as well as true ideals and does not always desert us after stripping us of our self-respect. A poet of doubt he is, who seldom attempts a solution; but he is also a puritan--a positivist puritan--and his scourgings are an equivalent for that _katharsis_, in the absence of which Aristotle denied the title of tragedy.
