Abstract
This eighth volume of the Collected Works of Jung comprises a collection of essays in which Jung struggles with the basic theoretical problems of his psychology. He brings an impressive erudition to his search for concepts, models and explanatory principles adequate to the refractory psychic phenomena with which he deals. In keeping with Jung's conviction that the psyche is "a thing of such infinite complexity that it can be observed and studied from a great many sides," the essays exhibit a variety of approaches, from the relatively empirical to the frankly speculative. The essays span some forty years of Jung's reflection and, thanks to their arrangement in thematic groupings by the editors, present an interesting study in the refinement of his thought and statement.--J.
