Symbols of Transformation is one of Jung’s major works. Originally published in 1912, it was extensively revised and expanded in the 1952 edition to incorporate Jung’s later mature understanding of the psyche. This work, in its first edition, heralded the irreversible split between Jung and Freud’s personalistic psychology. Edward Edinger’s Transformation of Libido goes straight to the heart of Jung’s early thinking and lays bare the essence of his major pioneering concepts. His interpretive clarity and incisive understanding of Jung’s ideas provide an invaluable resource in comprehending this seminal volume.
