Mark well: one can be a strict logician or grammarian and yet be full of fantasy and music. One can be a musician or a bead-player, and yet be devoted to law and order. The person whom we take as our ideal and try to emulate should be able at all times to exchange his art or science for any other, should allow the most crystal clear logic to radiate from his Bead Game and display the most creative fantasy in grammar. That is how we should be, and we should be prepared at any moment to be transferred to another post without opposition or allowing ourselves to become confused.
-- Hermann Hesse, Magister Ludi [Das Glasperlenspiel]
