I knew that writing a comparison of two points of view in psychoanalysis would be difficult when I proposed this project. But I didn't know how difficult. It was one of the hardest writing tasks I have ever had. The difficulty of the task, though, is interesting, at least in retrospect, because I believe that in it lies a hint of why the comparison of theories is seldom attempted. I have come up with three reasons for the difficulty. In the course of describing these reasons, I respond to John (Jack) C. Foehl's commentary. After that, I turn to the discussion by Don Troise.
