Book excerpt: The writings of C. G. Jung himself are the best place to read about all his main ideas—but where to start, when Jung's Collected Works run to more than eighteen volumes? Robert H. Hopcke's guide to Jung's voluminous writings shows exactly the best place to begin for getting a handle on each of Jung's key concepts and ideas—from archetypal symbols to analytical psychology to UFOs. Each chapter explains one of Jung's principal concerns, then directs the reader where to read about it in depth in the Collected Works. Each chapter includes a list of secondary sources to approach for further study—which the author has updated for this edition to include books published in the ten years since the Guided Tour's first appearance.
