“One sees clearly only with the heart. Anything essential is invisible to the eyes.” — Antoine De Saint-Exupéry, The Little Prince

“‘Where there is great love there are always miracles,’ he said at length. ‘One might almost say that an apparition is human vision corrected by divine love. I do not see you as you really are, Joseph; I see you through my affection for you.'” — Willa Cather, Death Comes for the Archbishop

“I do not perceive any thing with my sense-organs alone, but with a great part of my whole human being. Thus, I may say, loosely, that I ‘hear a thrush singing’. But in strict truth all that I ever merely ‘hear’ — all that I ever hear simply by virtue of having ears — is sound. When I ‘hear a thrush singing’, I am hearing, not with my ears alone, but with all sorts of other things like mental habits, memory, imagination, feeling and (to the extent at least that the act of attention involves it) will.  Of a man who merely heard in the first sense, it could meaningfully be said that ‘having ears’ (i. e. not being deaf) ‘he heard not’.” — Owen Barfield, Saving the Appearances

“Enthusiastic admiration is the first principle of knowledge and its last.” — William Blake

“May I be so converted and see with these eyes?” — William Shakespeare’s Benedick, Much Ado About Nothing
