" Stendhal knows the source of his greatest happiness and his worst misery: the reflexivity of his spiritual life. When he loves, enjoys beauty, feels free and unconstrained, he realizes not only the bliss of these feelings but, at the same time, the happiness of being aware of this happiness. But now that he ought to be completely absorbed by his happiness and feel redeemed from all his limitations and inadequacies, he is still full of problems and doubts: Is that the whole story?—he asks himself. Is that what they call love? Is it possible to love, to feel, to be delighted and yet to observe oneself so coolly and so calmly? Stendhal’s answer is by no means the usual one, which assumes the existence of an insurmountable gulf between feeling and reason, passion and reflexion, love and ambition, but is based on the assumption that modern man simply feels differently, is enraptured and enthusiastic differently from a contemporary of Racine or Rousseau. For them, spontaneity and reflexivity of the emotions were incompatible, for Stendhal and his heroes they are quite inseparable; none of their passions is so strong as the desire to be constantly calling themselves to account for what is going on inside them. Compared with the older literature, this self consciousness implies just as profound a change as Stendhal’s realism, and the overcoming of classical-romantic psychology is just as strictly one of the preconditions of his art as the abolition of the alternative between the romantic escape from the world and the anti-romantic belief in the world.
