“The qualities that make for excellence in children's literature can be summed up in a single word: imagination. And imagination as it relates to the child is, to my mind, synonymous with fantasy. Contrary to most of the propaganda in books for the young, childhood is only partly a time of innocence. It is, in my opinion, a time of seriousness, bewilderment, and a good deal of suffering. It's also possibly the best of all times. Imagination for the child is the miraculous, freewheeling device he uses to course his way through the problems of every day....It's through fantasy that children achieve catharsis.”
