What is the role of psychoanalysis in today's world? "Yesterday, Today and Tomorrow" presents a selection of papers written by Hanna Segal. The collection introduces the reader to a wide spectrum of insights into psychoanalysis, ranging from current thoughts on the nature of dreaming to new ideas about vision and disillusionment. Her long interest in factors affecting war is pursued in her examination of the psychotic factors, symbolic significance and psychological impact of the events of September the 11th, and the ensuing war on Iraq.The second half of the book discusses Segal's presentations to conferences and symposia from 1969-2000, this material is split into six sections: Models of the mind and mental processes; Psychoanalytic technique; Segal on Klein; Segal on Bion; Envy and narcissism; and Interviews. "Yesterday, Today and Tomorrow" is a masterly contribution to the field. Segal's clarity of thought and striking clinical illustrations make the book accessible to those new to the field as well as those acquainted with her seminal work.
