Various reasons have been given for romantic conversions to Catholicism--for example, the desire for confession (though the Catholic does not, like the Rousseauist, confess himself from the housetops), the æsthetic appeal of Catholic rites and ceremonies, etc. The sentence of Nietzsche puts us on the track of still another reason. The affinity of certain romantic converts for the Church is that of the jelly-fish for the rock. It is appropriate that Friedrich Schlegel, the great apostle of irony, should after a career as a heaven-storming Titan end by submitting to this most rigid of all forms of outer authority. For it should now be possible to return after our digression on paradox and the idea of the infinite and the perils of aimlessness, to romantic irony with a truer understanding of its significance. Like so much else in this movement it is an attempt to give to a grave psychic weakness the prestige of strength--unless indeed one conceives the superior personality to be the one that lacks a centre and principle of control. Man it has usually been held should think lightly of himself but should have some conviction for which he is ready to die. The romantic ironist, on the other hand, is often morbidly sensitive about himself, but is ready to mock at his own convictions. Rousseau was no romantic ironist, but the root of self-parody is found nevertheless in his saying that his heart and his head did not seem to belong to the same individual. Everything of course is a matter of degree. What poor mortal can say that he is perfectly at one with himself? Friedrich Schlegel is not entirely wrong when he discovers elements of irony based on an opposition between the head and the heart in writers like Ariosto and Cervantes, who love the very mediæval tales that they are treating in a spirit of mockery. Yet the laughter of Cervantes is not gypsy laughter. He is one of those who next to Shakespeare deserve the praise of having dwelt close to the centre of human nature and so can in only a minor degree be ranked with the romantic ironists.
