Now the pupil had become a teacher, and as such he had mastered the major task of his first period in office: the struggle to win authority and forge an identity of person and office. In the course of this he made two discoveries. The first was the pleasure it gives to transplant the achievements of the mind into other minds and see them being transformed into entirely new shapes and emanations — in other words, the joy of teaching. The second was grappling with the personalities of the students, the attainment and practice of authority and leadership — in other words, the joy of educating. He never separated the two, and during his magistracy he not only trained a large number of good and some superb Glass Bead Game players, but also by example, by admonition, by his austere sort of patience, and by the force of his personality and character, elicited from a great many of his students the very best they were capable of.
