agree that he probably did not mean it as a universal law, but rather meant that he prefers reading books that confuse and bewilder him. As an example, here's a really short story of his, "A Little Fable":
"
"Alas", said the mouse, "the whole world is growing smaller every day. At the beginning it was so big that I was afraid, I kept running and running, and I was glad when I saw walls far away to the right and left, but these long walls have narrowed so quickly that I am in the last chamber already, and there in the corner stands the trap that I am running into."
"You only need to change your direction," said the cat, and ate it up.
