Chapter III

The summer months of 1879, from the end of my Realschule period until my entrance into the Technische Hochschule, I spent entirely in such philosophical studies. In the autumn I was to decide my choice of studies with reference to my future career. I decided to prepare to teach in a Realschule. The study of mathematics and descriptive geometry would have suited my inclination. But I should have to give up the latter; for the study of this subject required a great many practice hours during the day in geometrical drawings, but in order to earn some money I had to have leisure to devote to tutoring. This was possible while attending lectures whose subject-matter, when it was necessary to be absent from lectures, could afterwards be taken up in readings, but not possible when one had to spend hours assigned for drawing regularly in the school.
