The rich world of his ancestors set the standards for Dietrich Bonhoeffer’s own life. It gave him a certainty of judgement and manner that cannot be acquired in a single generation. He grew up in a family that believed the essence of learning lay not in a formal education but in the deeply rooted obligation to be guardians of a great historical heritage and intellectual tradition.
