After this the teaching of Leibnitz slowly disappeared, and though a certain amount of optimism necessarily subsisted, the tendency of thought veered to the opposite direction. Fichte, Kant's immediate successor, declared, in direct contradiction to Leibnitz, that this world was the worst one possible, and was only consoled by thinking he could raise himself by the aid of pure thought into the felicity of the "supersensible." "Men," he says, "in the vehement pursuit of happiness grasp at the first object which offers to them any prospect of satisfaction, but immediately they turn an introspective eye and ask, 'Am I happy?' and at once from their innermost being a voice answers distinctly, 'No, you are as poor and as miserable as before.' Then they think it was the object that deceived them, and turn precipitately to another. But the second holds as little satisfaction as the first.... Wandering then through life, restless and tormented, at each successive station they think that happiness dwells at the next, but when they reach it happiness is no longer there. In whatever position they may find themselves there is always another one which they discern from afar, and which but to touch, they think, is to find the wished delight, but when the goal is reached discontent has followed on the way and stands in haunting constancy before them."[2] Schelling expressed himself more guardedly. As professional pantheist, he seemed to think that anything not rigidly vague and inaccessible was inconsistent with his philosophy. Still there was probably a secret revolt, some propelling impulse to deny his own syllogisms, and to bathe for once in some clear stream of common sense. In the "Nachtwachen," which he published under the pseudonym of Bonaventura, this incentive is evidently, though unsuccessfully, at work. It may be that the force of habit was too strong, but at any rate this rhapsody, which was intended to be a confession of the combat that he had waged with his belief, and a recognition of the immedicable misery of life, brings with it something of that impression of delirium which Poe and Doré not infrequently suggest. Nor was Hegel hostile to pessimism; he regarded it as an inevitable phase of universal evolution, and indeed its dawn as a science had then already broken. Meanwhile the poets had not been idle. Herder and Schiller had already attested the bitterness of life to unreluctant ears, and the number of suicides that were directly traceable to the appearance of Werther and his sorrows was instructively large. This phase of sentimentalism, which immediately preceded the riotous rebirth of the Romantic school, was not without its influence on Heine's verse, and in some measure affected the literary tone of the day.
