“If such as Thomas a Kempis and Bernard of Clairvaux are generous providers of the occasion of education, rather than reciters of precepts and beliefs, it is because they are seeking to be virtuous and to compose their own lives, rather than worrying that others might be vicious, leading discordant lives. Such teachers do the best that a teacher can do. In their own deliberations, they cast enough light that I may see something by it, if I happen to be looking.”
