The author focuses on some clinical implications of Bion's thought. He takes into particular consideration the great technical importance of Bion's concept of ‘waking dream thought’. He also proposes some developments of Bion's thought. Psychoanalytic exercises like those suggested by Bion are presented along with clinical material in order to render the author s theoretical–technical ideas as clear as possible. Furthermore, he deals with the fertile connection between Bion s theories and the field concept in psychoanalysis.
