`This book is a monumental achievement, and person-centred practitioners will be indebted to Goff Barrett-Lennard for many years to come. He has written no only a definitive study of the history of person-centred approach - what he calls a report of the evolutionary course of a human science - but also an accompanying commentary which is unfailingly enlightening, sometimes provocative and occasional lyrical - Brian Thorne, Emeritus Professor of Counselling, University of East Anglia and Co-Founder, Norwich Centre`I highly recommend this book as a reference source of major import, as bibliography, as history as art, and as a complex discussion of questions that plague the person-centred practitioner and the client-centred therapist - The Person-Centered Journal`If you only ever buy one book about the Person-Centred Approach, other than those written by Rogers himself, this is the one.
