Harnack’s theology was something like Archilochus’s proverbial fox, knowing many little things, while Barth’s theology was like a hedgehog, knowing one big thing. Bonhoeffer would side with the hedgehog, but he was in the fox’s seminar, and through his family and the Grunewald community, he had many ties with the fox. As a result of his intellectual openness, Bonhoeffer learned how to think like a fox and respect the way foxes thought, even though he was in the camp of the hedgehogs.
