The collective unconscious contains the whole spiritual heritage of mankind’s evolution, born anew in the brain structure of every individual.
His conscious mind is an ephemeral phenomenon that accomplishes all provisional adaptations and orientations, for which reason one can best compare its function to orientation in space.
The unconscious, on the other hand, is the source of the instinctual forces of the psyche and of the forms or categories that regulate them, namely the archetypes.
All the most powerful ideas in history go back to archetypes.
This is particularly true of religious ideas, but the central concepts of science, philosophy, and ethics are no exception to this rule.
In their present form they are variants of archetypal ideas, created by consciously applying and adapting these ideas to reality.
For it is the function of consciousness not only to recognize and assimilate the external world through the gateway of the senses, but to translate into visible reality the world within us. ~Carl Jung, CW 8, Para 342
