XI. The World of Dreams as a Transitional Current between the Physical-Natural World and the World of Moral Concepts

One such naturalist, who did not live in the second half of the 19th century but in the first, was Johannes Müller, who was the teacher of Haeckel. He was a man who could truly concentrate at all times. He was completely absorbed in whatever he was doing. The fact that one can really live like that, concentrated in whatever one is doing, sometimes leads to more; in some respects, as I will mention in a moment, it may have downsides. Johannes Müller, for example, was once asked about something during a summer course he taught. He said, “That is something I only know during the winter lectures, not in the summer.” He was so focused on the material for his summer lectures that he freely admitted that he only knew the rest during the winter.
