According to the author, what is a teacher's role?

This book suggests that teachers should inspire their students with love, but should also teach them the "hard words," the truly difficult truths painstakingly gathered by the wisdom of traditional culture. For Le Guin, the central truth seems to be that humanity must live and seek happiness in the world that is given. For her, human happiness arises from a freely chosen and social alliance on the side of creation. People are happy when they are creating the works and institutions that are essential for peace and well-being. In so doing, they oppose the natural forces of nonbeing that continuously break down what is made.
