This volume explores Jung's self psychology, its meaning and its application within the context of other contemporary theories of subjectivity. To describe Jung's self psychology more fully in the light of contemporary theories, the authors introduce twelve other self theories in a comparative analysis of the clinical case of a midlife man in psychotherapy. From Kohut and Piaget to Lichtenberg and Loevinger, the authors compare Jung's theories with other clinical and developmental approaches. The book's final chapter offers cogent suggestions for future use of Jung's self psychology. For Jungians, this book provides a contemporary context in which to read and systematize his work. For professionals in the larger therapeutic and educational communities, it offers an up-to-date introduction to a provocative and imaginative body of work that is a central chapter of modern theories of subjectivity.
