Quote from the FOREWORD by J. D. Sutherland:

Dr. Guntrip's qualifications for his task are exceptional. After a training in philosophical, religious, literary and social studies he became a full-time psychotherapist; and although not trained formally as a psycho-analyst he had a long personal analysis with Dr. W. R. D. Fairbairn. Ernest Jones in his Preface to Fairbairn's book, Psycho-analytic Studies of the Personality, wrote that Fairbairn's geographical isolation as a psycho-analyst was conducive to the indisputable originality of his ideas, ideas which would 'surely prove extremely stimulating to thought'. Jones was not given to making such prophecies readily and on this occasion he was certainly right. It does not require more than a look at the chapter headings to see that Dr. Guntrip has been greatly influenced by Fairbairn's contributions to personality theory; and as the author points out, Fairbairn's writings had made a great impression on him before his analysis.
