The two attitudes, or personality types, that Jung described were introversion and extroversion. According to Jung, introversion is the habitual attitude of consciousness that prefers introspection and solitary activity. Extroversion is the habitual attitude of consciousness that prefers active interaction with others and the environment. The following are basic introductions to the other components Jung described. It is basically a command center of personal identity, and it controls language, acquisition of knowledge, reflection, problem solving, and free will.
Complexes are the basic structural components of the unconscious.
A complex is a network of associated thoughts, images, fantasies, and repressed memories. It is useful to compare complexes to instincts. Like instincts, complexes produce an automatic, sometimes uncontrollable, response to a specific situation. But, unlike instincts, they are not purely innate. The ego can often neutralize the complex response, which is highly emotionally-charged, but complexes have different energy levels, or intensities, and sometimes cannot be controlled.
