The third volume in the Clarkson on Psychotherapy series brings together a fascinating selection of Professor Clarkson?s work. Most of the material has not previously been formally published, and ranges, from the beginnings of Gestalt through the importance - in life and therapy - of inborn constitutional temperamental types, to fundamental concerns in using philisophical discipline in psychology and Clarkson?s demonstration how the five-relational model can be applied to research, is impressive. Psychotherapists of all schools will find much to interest them in Clarkson on Psychotherapy 3, and students as well as practitioners will find the range and depth of papers not only demanding but also stimulating. This volume of papers starts with a paper about the beginnings of Gestalt which was first presented at the World Conference in 1996. Chapters 2 and 3 are here formally published for the first time although the material in it has been well-appreciated over some decades in ?samizdat? copies. Chapter 4 is a sample of Professor Clarkson?s work stressing the importance in life and in therapy of inborn constitutional temperamental types. Chapter 5 reports a joint research project into narratives of psychotherapy in modern English Literature.Chapter 6 surveys the field of Transpersonal psychology. Chapter 7 addresses some foundational concerns in using philosophical discipline in psychology. Finally, chapter 8 shows how the five-relations model can be applied to research.
