And then he went back to meet the fox.
“Goodbye,” he said.
“Goodbye,” said the fox. “And now here is my secret, a very simple secret: It is only with the heart that one can see rightly; what is essential is invisible to the eye.” (21.34-36)
This statement of the fox’s about being able to see best and most clearly “with the heart” is also the heart of the book. Seriously, though, this important secret is something the fox tells the prince and something the prince tells the narrator – in turn, it’s something all of them tell us, as readers. This is the “secret,” the big deal around which this book is centered, and the clue that helps us understand all the things happening within it. Insides are more important than outsides. You can’t just look at things with your eyes. If you do, you’ll miss what’s really “essential” about them.
