This book discusses the body-psyche relationship - in a historical context - through the contributions that psychoanalytic theory and Jungian theory - each with its own framework - bring to understanding the subject. It is didactic material that offers an initiation for those who wish it. It also provides an understanding of the participation of Freud's and Jung's praxis in the body-psyche relationship and in contemporary psychosomatic apprehensions. The transition from the paradigm of modernity to the paradigm of complexity - which we have been witnessing ever since - and the concept of transdisciplinarity, pointed out by Edgar Morin, have been emphasised here in the current entanglement of the sciences and are postulated, in this dissertation, inexorably, as the ideal model for their applicability.
