Quote by Arthur Schopenhauer
Books are like a mirror. If an ass looks in, you can't expect an angel to look out.
Summary
This quote suggests that the kind of knowledge or lessons one gains from books is dependent on their own mindset and willingness to learn. It's emphasizing that if someone lacks intelligence or insight and approaches books with a closed mind, they won't gain anything valuable from them. The metaphor of a mirror highlights the idea that books reflect one's own qualities and attitudes, essentially implying that the quality of one's reading experience depends on their own perception and receptivity.
