ABSTRACT
Foreword. In the remaining chapters of this book I am going to deal essentially with concepts which can be employed only partially in present-day clinical work but which, I feel, will become important in due time. It will be a challenge to future generations of psychoanalysts to understand how and when these concepts may apply and to create new notions which may serve to modify or complete them. If they respond to this, perhaps not only psychoanalysis but also mathematics and epistemology could be enriched. Perhaps too the aspects, either of knowledge or of being, where there is unity in nature will become more apparent. Psychoanalysis, especially through the study of dreams, offers unique opportunities of discovering recondite aspects of being, some of which may even eventually apply to other subjects.
