I don't think Lewis made the distinction so much (though he might have) -- I'm using my own words to describe some ideas I'm getting from Barfield. Lewis would have been familiar with the idea in Barfield's terms, but I don't know that he ever used it. (Now I'm tempted to go looking for Eustace's conversation and see if it's Barfieldian!)

I wonder how much understanding of the stars is shaped by how well we can see them. They're so easy to abstract when we're thinking about the science, but faced with thousands of glittering lights above, I find it hard to remember the "facts" and am much more drawn to their beauty. It's almost like two separate things -- the stars I see and the stars I've read about in books. And even though the science is wrong, I think the woman in Kentucky has something right -- if we forget that these big balls of gas thousands of miles away are also points of light in the darkness, we've lost something important.
