The person-centred approach is one of the most popular, enduring and respected approaches to psychotherapy and counselling. "Person-Centred Therapy" returns to its original formulations to define it as radically different from other self-oriented therapies. Keith Tudor and Mike Worrall draw on a wealth of experience as practitioners, a deep knowledge of the approach and its history, and a broad and inclusive awareness of other approaches. This significant contribution to the advancement of person-centred therapy: examines the roots of person-centred thinking in existential, phenomenological and organismic philosophy; locates the approach in the context of other approaches to psychotherapy and counselling; shows how recent research in areas such as neuroscience support the philosophical premises of person-centred therapy; and challenges person-centred therapists to examine their practice in the light of the history and philosophical principles of the approach. "Person-Centred Therapy" offers new and exciting perspectives on the process and practice of therapy, and will encourage person-centred practitioners to think about their work in deeper and more sophisticated ways.
