...Finally, what is Reason? You have often asked me; and this is my
answer:--
   Whene'er the mist, that stands 'twixt God and thee,
   [Sublimates] to a pure transparency,
   That intercepts no light and adds no stain--
   There Reason is, and then begins her reign!
   But alas!
  -----------'tu stesso, ti fai grosso
  Col falso immaginar, sì che non vedi
  Ciò che vedresti, se l'avessi scosso.'
(Dante, Paradiso, Canto 1, lines 88-90)
