Between tilting at windmills Don Quixote stopped at a printing press. This press was printing books of his adventures.
It marked the first time in literature that a book featured in itself.
And the first time that a character could reflect on their actions. Read for himself how the world is affected by those actions and how it affects others.
He did not. He stuck to his lance and continued following his fancies.
I wonder if I would stop and read a book about my being in the world.
And I wonder which takes the most courage: Reading, or sticking to your lance.
