One of Jung's early works, first published in German (titled Wandlungen und Symbole der Libido) in 1912. A more recent publisher's (Dover) description describes the book as "his most famous and influential work," in which "Jung made a dramatic break from the psychoanalytic tradition established by his mentor, Sigmund Freud." by using dreams, mythology, and literature to define the universal patterns of the psyche. "In Psychology of the Unconscious, Jung seeks a symbolic meaning and purpose behind a given set of symptoms, placing them within the larger context of the psyche. The 1912 text examines the fantasies of a patient whose poetic and vivid mental images helped Jung redefine libido as psychic energy, arising from the unconscious and manifesting itself consciously in symbolic form. Jung's commentary on his patient's fantasies offers a complex study of symbolic psychiatry and foreshadows his development of the theory of collective unconscious and its constituents, the archetypes."
