Ta-Nehesi Coates on hope and historians:
... I think that a writer wedded to “hope” is ultimately divorced from “truth.” Two creeds can’t occupy the same place at the same time. If your writing must be hopeful, then there’s only room for the kind of evidence which verifies your premise. The practice of history can’t help there. Thus writers who commit themselves to only writing hopeful things, are committing themselves to the ahistorical, to the mythical, to the hagiography of humanity itself. I can’t write that way—because I can’t study that way. I have to be open to things falling apart. Indeed, much of our history is the story of things just not working out.
