Last week, Mona Charen had a column emphasizing the importance of the teacher: Of all the things that go into a good education, it’s hard to beat an excellent teacher. This reminded me of a favorite statement of mine, which I found while studying the Nobel Peace Prize. It comes from a Dutchman who was the first U.N. high commissioner for refugees. That office won the peace prize for 1954. And, in his lecture, Gerrit Jan van Heuven Goedhart said, “Many years ago, I participated in a discussion on the problem of international education. After many experts had presented their complicated theories, an old headmaster of a certain school got up and quietly said, ‘There is only one system of education — through love and one’s own example.’”
