I’ve never met Orcs or Ents or Elves — but the feel of it, the sense of a huge past, of lowering danger, of heroic tasks achieved by the most apparently unheroic people, of distance, vastness, strangeness, homeliness (all blended together) is so exactly what living feels like to me. Particularly the heart-breaking quality in the most beautiful places, like Lothlorien. And it is so like the real history of the world: “Then, as now, there was a growing darkness and great deeds were done that were not wholly in vain.” Neither optimism (this is the last war and after it all will be lovely forever) nor pessimism (this is the last war and all civilization will end), you notice. No. The darkness comes again and again and is never wholly triumphant nor wholly defeated.
