“I think seeing happens partly through the eyes, but not entirely.”

“I had very good eyes once. Though it's another thing to say what I saw. In my experience, it is entirely possible to watch something happen and not to see it at all.”

“Look at my glasses. I can't even see that there are any stars in the sky without them, but it's not the glasses that are doing the seeing, it's me, Madeleine. I don't think Father's eyes are seeing now, but he is. And maybe his brain isn't thinking, but a brain's just something to think through, the way my glasses are something to see through.”

“And these are your reasons, my lord?""Do you think I have others?" said Lord Vetinari. "My motives, as ever, are entirely transparent."Hughnon reflected that 'entirely transparent' meant either that you could see right through them or that you couldn't see them at all.”

“The eye through which I see God is the same eye through which God sees me; my eye and God's eye are one eye, one seeing, one knowing, one love.”

“I see the beauty of the world through your eyes. I can't see it through my own.”
