He kept on working, however, and made an energetic effort to discover and define the moral values which he wished to propound. But in vain; do what he would, the problem of his third book--_Principle of a New Evaluation_--remained unsolved. "We may here transcribe the more precise definition with which we are furnished by another draft. "_Third Book:_ the problem of the legislator. To bind anew the unregulated energies in such a manner that they are not mutually annihilated by running foul of one another; to mark the _real augmentation_ of force." What does this mean? What real augmentation, what real direction of things is indicated us by these words? Is it an augmentation of intensity? Then every shade of energy, provided it be intense, will be good. But we must not take it in this sense. Nietzsche selected, preferred, excluded. This augmentation is then the sign of an order, of a natural hierarchy. But in every hierarchy there must be a criterion by which the ranks are distributed; what should this criterion be? Nietzsche would formerly have said: It will be my logical affirmation, the beliefs which I shall have given. Does he still think it? Doubtless; his thoughts hardly vary. But his audacity was lessened by his sorrows, his critical mind had been rendered more exacting by long indecisions. He desired, he sought, he seemed to ask science, the "doctor-philosopher," for a real basis which all his habits of thought refused him. Mournful news completed the ruin of his courage. Heinrich von Stein died, before his thirtieth year, of a heart failure. "This has put me out of my senses," wrote Nietzsche to Peter Gast; "I truly loved him. I always thought that he was reserved for me some day. He belonged to that little number of men whose _existence_ rejoiced me; and he too had great confidence in me.... In this very place how we laughed! ... He paid a two days' visit to Sils, he had not a glance for Nature or Switzerland--he came straight from Bayreuth; he went back straight to Halle, to his father;--one of the rarest and most delicate homages I have ever received. It made an impression. He had said at the hotel: 'If I come, it is not for the Engadine.'" Three weeks passed. He complained of bitter inclinations, of susceptibility which lowered his soul. Nevertheless, he announced a new work. What was it? * * * * *
