What is personal identity? What forms its nature? Is there a difference between identity and personality? What makes a 'person' an individual, and what exactly is the person? What role is played by character, nature, environment, society, values and destiny in defining and substantiating a personal identity? The dialectics of different disciplinary approaches and knowledges, as well as different theoretical-speculative perspectives and traditions, can be more productive in deepening and readdressing problems concerning human identity. It is by following this line of reasoning that this book analyses and discusses the above questions from the dialectical perspective of psychoanalysis, psychiatry and philosophy. It offers a new point of departure for theoretical-scientific and speculative advancement. The book also reconsiders the fundamental characteristics of a dynamic and hermeneutic vision of identity, tracing a middle-way perspective and, at the same time, absorbing Wilfred Bion's idea of transformation and Paul Ricoeur's philosophy of translation.
