In 1890 Steiner was summoned to collaborate in the archives of Goethe and Schiller at Weimar, to superintend the re-editing of Goethe's scientific works. Shortly after, he published two important works, _Truth and Science_ and _The Philosophy of Liberty_. "The occult powers that guided me," he says, "forced me to introduce spiritualistic ideas imperceptibly into the current literature of the time." But in these various tasks he was but studying his ground while trying his strength. So distant was the goal that he did not dream of being able to reach it as yet. To travel round the world in a sailing vessel, to cross the Atlantic, the Pacific and the Indian Ocean, in order to return to a European port, would have seemed easier to him. While awaiting the events that would allow him to equip his ship and to launch it on the open sea, he came into touch with two illustrious personalities who helped to determine his intellectual position in the contemporary world. These two persons were the celebrated philosopher, Friedrich Nietzsche, and the no less famous naturalist, Ernst Haeckel. Rudolf Steiner had just written an impartial treatise on the author of _Zarathustra_. In consequence of this, Nietzsche's sister begged the sympathetic critic to come and see her at Naumburg, where her unhappy brother was slowly dying. Madame Foerster took the visitor to the door of the apartment where Nietzsche was lying on a couch in a comatose condition, inert, stupified. To Steiner there was something very significant in this melancholy sight. In it he saw the final act in the tragedy of the would-be superman. Nietzsche, the author of _Beyond Good and Evil_, had not, like the realists of Bismarckian imperialism, renounced idealism, for he was naturally intuitive; but in his individualistic pride he sought to cut off the spiritual world from the universe, and the divine from human consciousness. Instead of placing the superman, of whom he had a poetic vision, in the spiritual kingdom, which is his true sphere, he strove to force him into the material world, which alone was real in his eyes. Hence, in that splendid intellect arose a chaos of ideas and a wild struggle which finally brought on softening of the brain. To explain this particular case, it is needless to bring in atavism or the theory of degeneracy. The frenzied combat of ideas and of contradictory sentiments, of which this brain was the battlefield, was enough. Steiner had done justice to all the genius that marked the innovating ideas of Nietzsche, but this victim of pride, self-destroyed by negation, was to him none the less a tragic instance of the ruin of a mighty intellect which madly destroys itself in breaking away from spiritual intelligence.
