This book is based on various cases whose common factor is how the psychoanalytical setting is created: the internalization and realization inside the patient's mind with the feeling of fixed hours and transferential relation with the psychoanalyst. Referring to the great masters of psychoanalysis, Rosenfeld guides us step by step through the mysterious terrain of the mind, especially in its most regressive, primitive and psychotic aspects. Thomas Ogden, commenting on the papers collected here, wrote that 'they represent two of the most important contributions of the past decade to the understanding of the psychoanalytic treatment of psychotic patients'.
