From A Commonplace Blog:
No other writer I can name has accepted with such utter self-abnegating devotion to what I can only call, in a blatant allusion to John Erskine’s famous 1915 essay, the moral obligation to write well. This is, I believe, the sum and substance of what it means to respect the institution of literature. The writer shoulders a double burden.
