This book explores the analyst's countertransference experience in clinical settings from a number of theoretical perspectives in order to develop a transtheoretical definition of countertransference. Stemming from an examination of the definition of countertransference itself, the author utilizes a philosophical hermeneutic approach to ask how pathological countertransference develops, how analysts separate themselves from the patient's experience, and what analysts should do to prevent their countertransference response from interfering with treatment. Through the unique hermeneutic methodology, philosophical themes within selected writings are explored as a way of gaining a deeper meaning and understanding of countertransference. By re-interpreting these selected writings in a new light, the book develops a transtheoretical definition and approach to countertransference. As such, the author offers a timely reassessment of the meaning and understanding of countertransference as it has evolved over the past century, going from being considered an obstacle to treatment brought on by the analyst's unconscious conflicts to being understood as a way of communicating and understanding the patient's unconscious material. It also provides a unique pathway through various depth psychological, therapeutic, and theoretical approaches to countertransference, foregrounding the significance and therapeutic value of the concept and seeking a new transtheoretical definition. This volume will appeal to scholars and researchers of psychology and mental health.
