> “It is our knowledge — the things we are sure of — that makes the world go wrong and keeps us from seeing and learning,” That's not knowledge - that's belief. > Read books are far less valuable than unread ones. Eh, I agree having books you can refer to is useful, but I would argue you can't really refer to them unless you've read them. If they're really worthwhile, you'll read them, learn something, and keep them…
Another example of "knowledge" being used in the sense meant by the article is this:
"It ain't what you don't know that gets you into trouble. It's what you know for sure that just ain't so." --Mark Twain
