I will rally to the cry "Pass away, refuge of abstractions." How fitting that you quote Bonhoeffer here, the rare theologian who was willing to give his life away for the truth. I wonder if one of the reasons the romantic poets (Shelly, Byron, Wordsworth, Coleridge) were all political and social activists as well as writers was because, unlike philosophy and theology, poetry does not allow one to dwell in the clouds of abstraction but forces one into the imminent. And in the imminent, one must act. Musings.

Also—T.S. Eliot, Kierkegaard, Bonhoeffer, Calvin, Chesterton, and Augustine. All in one short essay. Wonderful curation of thinkers!
