The unifying theme of the papers collected in this volume is the individuation process as outlined by C.G. Jung and adopted and extended by later generations of scholars and psychoanalysts working in the field of analytical psychology. Individuation is a major contribution to developmental psychology and encompasses the entire lifetime no matter its duration. The unique feature of this notion of human development is that it includes spiritual as well as psychosocial features. The essays in this volume explain and expand on Jung’s fundamental contributions.
