With its publication of the Collected English Papers of Wolfgang Giegerich, Spring Journal Books makes available the work of one of archetypal psychology's most brilliant theorists. The product of over three decades of critical reflection, Giegerich's English papers are collected in four volumes: The Neurosis of Psychology (Vol. 1), Technology and the Soul (Vol. 2), Soul-Violence (Vol. 3), and The Soul Always Thinks (Vol. 4) This volume takes its title from Giegerich's ground-breaking paper, 'On the Neurosis of Psychology, or The Third of the Two'. The 'third' referred to in the title is psychology itself as the theory in which the two, patient and analyst, are contained as they engage with one another in the analytic process. By applying to psychology itself the ideas that it draws upon when thinking about the patient, Giegerich establishes the basis for a psychology that defines itself as the discipline of interiority. Topics include Neumann's history of consciousness, Jung's thought of the self, the question of a Jungian identity, projection, the origin of psychology, and more.
