Fundamental to analytical psychology is the theory of complexes, which recognizes the complex nature of the unconscious and defines complexes as 'living units of the unconscious psyche.'  It also recognizes the complex nature of the ego, which, as the center of consciousness, forms the central complex in the psychic system.\r\n\r\nThis conception of the ego, substantiated by the psychological and psychopathological findings, is one of the distinctive features of analytical psychology:\r\n \r\n>The ego complex is a content of consciousness as well as a condition of consciousness, for a psychic element is conscious to me so far as it is related to the ego complex.  But so far as the ego is only the center of my field of consciousness, it is not identical with the whole of my psyche, being merely one complex among other complexes.\r\n\r\n>Jung, Psychological Types
