A man, the wise have always insisted, should look with reverence but not with wonder on himself. Rousseau boasts that if not better than other men, he is at least different. By this gloating sense of his own otherwiseness he may be said to have set the tone for a whole epoch. Chateaubriand, for instance, is quite overcome by his own uniqueness and wonderfulness. At the most ordinary happenings he exclaims, as Sainte-Beuve points out, that such things happen only to him. Hugo again is positively stupefied at the immensity of his own genius. The theatricality that one feels in so much of the art of this period arises from the eagerness of the genius to communicate to others something of the amazement that he feels at himself.
