"Jung only used the term ‘psychoid’ occasionally, and mostly in works published towards the end of his life. Yet the term signals themes of the relationship between mind and body and between mind and matter that are pivotal for an understanding of his entire psychological project. In this book, through detailed historical reconstruction and innovative empirical research, Ann Addison has clarified as never before both what Jung meant by ‘psychoid’ and how the concept now informs the thought and practice of contemporary analysts. Lucid, authoritative, and rich in both clinical and scholarly insights, Jung’s Psychoid Concept Contextualised deserves to become a key reference point in the study of Jungian theory and praxis."Professor Roderick Main, Department of Psychosocial and Psychoanalytic Studies, University of Essex."Depth Psychology in the 21st century is undergoing some fundamental changes and expansions. Dr. Addison’s reexamination of the concept of the psychoid is a very valuable contribution in furthering our understanding the full range of the psyche, especially its fuzzy margins. By embracing the new holism found in complexity theory she grounds and revivifies the links between psyche and nature, moving us towards a much needed re-visioning of our models of consciousness and the mind."Joe Cambray, Ph.D., IAAP, President, Pacifica Graduate Institute.
