The Legend of Death. John Milbank

The Earth's thin crust of organic matter and the still thinner crust of the spirit is the most concentrated, the most suggestive part of the cosmos.

Poetry attends to the resultant human diagonal. –from the preface to the first sequence, «On the Diagonal: Metaphysical Landscapes»
