This is not from a book, but is rather from Dr. Seuss himself. Here he points out the importance of fantasy, which his books all seem to delve into. From the way they talk to the way they look, his characters forced readers to escape into the world he dreamt up. Seuss himself even said that he wouldn’t show up to a dinner party with his characters, as they’re too zany and unpredictable. It also seems like he’s saying that fantasy helps you turn the focus inward, rather than outward, you learn about yourself in the process.
