He insists, again and again: 'Environment has a great influence upon the forms in which the imagination creates'; and, in a tone of half-burlesque, but with something serious in his meaning, he declares that wine had something to do with the exaltation of _Brand_ and _Peer Gynt_, and sausages and beer with the satirical analysis of _The League of Youth_. And he adds: 'I do not intend by this to place the last-mentioned play on a lower level. I only mean that my point of view has changed, because here I am in a community well ordered even to weariness.' He says elsewhere that he could only have written _Peer Gynt_ where he wrote it, at Ischia and Sorrento, because it is 'written without regard to consequences--as I only dare to write far away from home.' If we trace him through his work we shall see him, with a strange docility, allowing not only 'frame of mind and situation in life,' but his actual surroundings, to mould his work, alike in form and in substance. If he had never left Norway he might have written verse to the end of his life; if he had not lived in Germany, where there is 'up-to-date civilisation to study,' he would certainly never have written the social dramas; if he had not returned to Norway at the end of his life, the last plays would not have been what they were. I am taking him at his word; but Ibsen is a man who must be taken at his word. What is perhaps most individual in the point of view of Ibsen in his dramas is his sense of the vast importance trifles, of the natural human tendency to invent or magnify misunderstandings. A misunderstanding is his main lever of the tragic mischief; and he has studied and diagnosed this unconscious agent of destiny more minutely and persistently than any other dramatist. He found it in himself. We see just this brooding over trifles, this sensitiveness to wrongs, imaginary or insignificant, in the revealing pages of his letters. It made the satirist of his earlier years; it made him a satirist of non-essentials. A criticism of one of his books sets him talking of wide vengeance; and he admitted in later life that he said to himself, 'I am ruined,' because a newspaper had attacked him overnight.
