In the German classical gymnasium in which I was educated, our interest and learning was essentially directed toward the humanities, and so was my reading outside of school. Nevertheless, the young men in the gymnasium generally tended to choose natural sciences as a profession. When I had to decide between natural sciences and philosophy before entering the university, I did not know which to choose. In deciding on natural science, I was certain that I would use it only as a basis for becoming a physician. Medicine alone appeared suited to my inclination — to deal with human beings.
