Written by pioneering analyst and creative thinker, James Grotstein, A Beam of Intense Darkness offers a thorough overview and illuminating insight into the often-complex work of W. R. Bion. This psychoanalytic classic sees Grotstein introduce over 30 key Bionian theories, comprehensively explaining them to the reader before offering his own insight and commentary. Grotstein first encountered Bion as his analysand and, later, as his friend. This book offers a level of insight only possible through such a close relationship, and offers a dialogue between Bion and Grotstein as they delve into the inner workings of the human psyche. Throughout, Grotstein offers his own original thoughts on topics such as projective trans identification, transcendent position and the truth drive. With a new introduction from Nicola Abel-Hirsch, this book is an essential read for anyone interested in Bion's work and legacy.
