Imagination and the Arts in C. S. Lewis; Journeying to Narnia and Other Worlds, by Peter J. Schakel. Columbia, MO Univ of Missouri Press 2002; First Edition.
From the publisher:
“Imagination has long been regarded as central to C. S. Lewis’s life and to his creative and critical works, but this is the first study to provide a thorough analysis of his theory of imagination, including the different ways he used the word and how those uses relate to each other. Imagination and the Arts in C. S. Lewis will appeal to students and teachers of both children’s literature and twentieth-century British writers. It will also be of value to readers who wish to compare Lewis’s creations with more recent imaginative works such as the Harry Potter series.”
