This book contains a series of essays that explore the concept of unconsciousness as it is situated between phenomenology and psychoanalysis. A leading goal of the collection is to carve out phenomenological dimensions within psychoanalysis and, equally, to carve out psychoanalytical dimensions within phenomenology. The book examines the nature of unconsciousness and the role it plays in structuring our sense of self. It also looks at the extent to which the unconscious marks the body as it functions outside of experience as well as manifests itself in experience. In addition, the book explores the relationship between unconsciousness and language, particularly if unconsciousness exists prior to language or if the concept can only be understood through speech. The collection includes contributions from leading scholars, each of whom grounds their investigations in a nuanced mastery of the traditional voices of their fields. These contributors provide diverse viewpoints that challenge both the phenomenological and psychoanalytical traditions in their relation to unconsciousness.
