Friedrich Schlegel sought illustrious sponsors in the past for his theory of irony. Among others he invoked the Greeks and put himself in particular under the patronage of Socrates. But Greek irony always had a centre. The ironical contrast is between this centre and something that is less central. Take for example the so-called irony of Greek tragedy. The tragic character speaks and acts in darkness as to his impending doom, regarding which the spectator is comparatively enlightened. To take another example, the German romanticists were especially absurd in their attempts to set up Tieck as a new Aristophanes. For Aristophanes, however wild and irresponsible he may seem in the play of his imagination, never quite loses sight of his centre, a centre from which the comic spirit proceeds and to which it returns. Above all, however far he may push his mockery, he never mocks at his own convictions; he never, like Tieck, indulges in self-parody. A glance at the parabasis of almost any one of his plays will suffice to show that he was willing to lay himself open to the charge of being unduly didactic rather than to the charge of being aimless. The universe of Tieck, on the other hand, is a truly romantic universe: it has no centre, or what amounts to the same thing, it has at its centre that symbol of spiritual stagnation, the philistine, and his inability to rise above a dull didacticism. The romanticist cherishes the illusion that to be a spiritual vagrant is to be exalted on a pinnacle above the plain citizen. According to Professor Stuart P. Sherman, the Irish dramatist Synge indulges in gypsy laughter from the bushes,[173] a good description of romantic irony in general.
