"This book represents the fruition of four years labor--most of it, fortunately, a labor of love. The idea of translating these papers, originating with Ernest Angel, was welcomed by Basic Books because of their enthusiasm for bringing out significant new material in the sciences of man. I was glad to accept their invitation to participate as one of the editors since I, too, had long been convinced of the importance of making these works available in English, particularly at this crucial moment in the development of modern psychiatry and psychology. We asked Dr. Ellenberger to join us as the third editor because of his extensive knowledge of the literature of phenomenological and existential psychiatry and his clinical experience in using these methods in Switzerland. He and Mr. Angel are chiefly responsible for the selection of the particular papers translated. In our introductory chapters, Dr. Ellenberger and I have undertaken the task of making a bridge between these contributions and American psychiatry and psychology, while Mr. Angel has borne the major weight of the translations themselves"--Preface.
