The editors of this volume started with a good idea and abundant good intentions. Volume II of Ralph Greenson's much used, one- of-a-kind textbook of psychoanalysis was never written. His illness and subsequent death appeared to make it certain that it never would be, but years later an outline for the planned second volume and preliminary drafts of several chapters were found among his papers. The editors designed a volume that might accomplish Greenson's intentions according to his original design and might also serve as testimonial and tribute to this creative clinician, teacher, and thinker.
