Unlike Sigmund Freud, who believed religion to be an illusory wish
fulfillment for the weak minded, Carl Jung advocated religion as an
indispensable part of an individual's psychological development. Jung viewed the
mind as having three components: the ego, the personal unconscious, and the
collective unconscious. Freud's vision of the mind did not include a
collective unconscious. Instead, Freud proposed a moral super-ego, which grew to
become the mind's administrator according to a learned sense of morality. Jung
believed the self-actualizing properties of Freud's super ego pre-exist in the
mind as a collective unconscious which is to be discovered through introspection
as opposed to learned from experience.
