Chapter III

In the library I spent my time on Herbart's metaphysics through Zimmermann's Aesthetic als Formwissenschaft[^9] which was written from Herbart's point of view. Together with this I made a thorough study of Haeckel's Generelle Morphologie.[^10] I may say that everything which I felt to be entering into me through the lectures of Schröer and Zimmermann, as well as the reading I have mentioned, became a matter of the deepest mental experience. Riddles of knowledge and of world conception shaped themselves within me from these things.
