Reason
by Samuel Taylor Coleridge

... 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)
