In Archetype of the Absolute: The Union of Opposites in Mysticism, Philosophy and Psychology, Sanford Drob traces the problem of the opposites in the history of ideas and develops the thesis that apparent oppositions in philosophy, including those that underlie competing paradigms in psychology, are complementary rather than contradictory. The doctrine of the complementarity and union of opposites underlies the mysticism of the Tao and the Kabbalah, the dialectical thinking of Hegel, the psychology of C.G. Jung, and various interpretations of quantum physics, and it has been spoken of as the master archetype. In this intellectual tour de force, Drob draws upon thinkers from Heraclitus to Jacques Derrida and Slajov Zizek, to resolve metaphysical and psychological puzzles and reconcile a wide range of oppositions, including those between determinism and free-will, realism and idealism, reason and imagination, and theism and atheism. Drob reveals the significance of the doctrine of the union of opposites in the Kabbalah and other mystical traditions, provides a deep examination of Hegel’s dialectical efforts to overcome contradiction, and fully explores C. G. Jung’s notion that the self is a coincidence of opposites. He shows that a full conceptual analysis of competing paradigms in psychological theory and practice reveals them to be complementary and interdependent. Concluding chapters consider the fundamental oppositions between sign and signified, subject and object, and identity and difference, and explore the possibility (and limits) of a rational-mystical ascent to the Absolute.
