This book is an attempt to understand the therapeutic experience of psychological individuation. It represents current psychoanalytic research in the service of illuminating a more clinically effective theory and methodology for psychoanalytic practice. In the text, the author presents his conviction, drawn from experience, that indivisibility is an accessible and intermittent experience of psychological living and a necessary prerequisite for enduring psychological health and maturation. His recommendations concerning the clinical practice of psychoanalysis are meant to reorganize expectations of psychoanalytic treatment to include an awareness of each patient¹s need for an individuation. Section 1, Psychological Representation, explores the problem of mental representation that promotes unconscious individuality. Section 2, Individuation of Human Experience, explores the experience of individuation specifically. Section 3, Individuation in Psychoanalysis, revisits the psychology of representation as it appears clinically in the building blocks of character, personality, and identity. Section 4, The Psychoanalytic Presence, elaborates upon the issue of an optimal interpersonal context for the experience of emergence and transformation of psychological representations. This book represents an important contribution to the theory and practice of contemporary psychoanalysis and is a theoretical and clinical revision of current perspectives in relational psychoanalysis. The book will be very useful to psychologists, psychiatrists, and social workers who are interested in deepening the effectiveness of their work by encouraging the direct experience of a patient¹s unique individuality.
