... 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)
