This divergence over the nature of the unconscious has been cited as a key aspect of Jung's famous split from Sigmund Freud and his school of psychoanalysis. Some commentators have rejected Jung's characterization of Freud, observing that in texts such as "Totem and Taboo" (1913) Freud directly addresses the interface between the unconscious and society at large. Jung himself said that Freud had discovered a collective archetype, the Oedipus complex, but that it "was the first archetype Freud discovered, the first and only one".
