In Love and its Vicissitudes André Green and Gregorio Kohon draw on their extensive clinical experience to produce an insightful contribution to the psychoanalytic understanding of love.In Part I, 'To Love or Not to Love - Eros and Eris', André Green addresses some important questions: What is essential to love in life? What, in the psychoanalytic method, is related to it? Should we understand love by referring to its earliest and most primitive roots? Or should we take as our starting point the experience of the adult? He argues that while science has made no contribution to our understanding of love, art, literature and especially poetry are the best introduction to it. In Part II, Love in the Time of Madness, Gregorio Kohon provides a detailed clinical study of an individual suffering a psychotic breakdown. He describes how the exclusive as well as the intense lasting dependence to a primary carer create the conditions for a "normal madness" to develop. This is not only at the source of later psychotic states and the perversions but also at the origin of all forms of love, as demonstrated in its re-appearance in the situation of transference.Love and its Vicissitudes moves beyond conventional psychoanalytic discourse to provide a stimulating and revealing reflection on the place of love in psychoanalytic theory and practice.
