What can we know about the nature of reality? A wonderful story for motivating conversations about this question is Harold and the Purple Crayon by Crockett Johnson. First published in 1955, the story begins with Harold deciding, “after thinking it over for some time,” to take a walk in the moonlight. No moon is out, so Harold takes his purple crayon and draws one, and then he draws something to walk on. Harold goes on to draw a forest in which he wanders, a dragon that ends up frightening him, an ocean in which he almost drowns and a boat which saves him, a beach, a lunch to eat, etc.
