The preface is in the form of a rather tetchy report by a psychoanalyst who has been consulted by Zeno Corsini. The analyst says that he must apologize for having suggested that ‘my patient write his autobiography, students of psychology will frown on this new departure. But he was an old man . . . he seemed so curious about himself.’ His patient has terminated the analysis, so the analyst is publishing his patient’s notes ‘in revenge, and I hope he is displeased’.
