This passage may be said to foreshadow the two types of art and literature that have been prevalent since Rousseau--romantic art and the so-called realistic art that tended to supplant it towards the middle of the nineteenth century.[71] This so-called realism does not represent any fundamental change of direction as compared with the earlier romanticism; it is simply, as some one has put it, romanticism going on all fours. The extreme of romantic unreality has always tended to produce a sharp recoil. As the result of the wandering of the imagination in its own realm of chimeras, one finally comes to feel the need of refreshing one’s sense of fact; and the more trivial the fact, the more certain one is that one’s feet are once more planted on _terra firma_. Don Quixote is working for the triumph of Sancho Panza. Besides this tendency of one extreme to produce the other, there are special reasons that I shall point out more fully later for the close relationship of the romanticism and the so-called realism of the nineteenth century. They are both merely different aspects of naturalism. What binds together realism and romanticism is their common repudiation of decorum as something external and artificial. Once get rid of decorum, or what amounts to the same thing, the whole body of “artificial” conventions, and what will result is, according to the romanticist, Arcadia. But what actually emerges with the progressive weakening of the principle of restraint is _la bête humaine_. The Rousseauist begins by walking through the world as though it were an enchanted garden, and then with the inevitable clash between his ideal and the real he becomes morose and embittered. Since men have turned out not to be indiscriminately good he inclines to look upon them as indiscriminately bad and to portray them as such. At the bottom of much so-called realism therefore is a special type of satire, a satire that is the product of violent emotional disillusion. The collapse of the Revolution of 1848 produced a plentiful crop of disillusion of this kind. No men had ever been more convinced of the loftiness of their idealism than the Utopists of this period, or failed more ignominiously when put to the test. All that remained, many argued, was to turn from an ideal that had proved so disappointing to the real, and instead of dreaming about human nature to observe men as coolly, in Flaubert’s phrase, as though they were mastodons or crocodiles. But what lurks most often behind this pretence to a cold scientific impassiveness in observing human nature is a soured and cynical emotionalism and a distinctly romantic type of imagination. The imagination is still idealistic, still straining, that is, away from the real, only its idealism has undergone a strange inversion; instead of exaggerating the loveliness it exaggerates the ugliness of human nature; it finds a sort of morose satisfaction in building for itself not castles but dungeons in Spain.
