"Whereas we think in periods of years, the unconscious
thinks and lives in terms of millennia. So when something happens that seems to
us an unexampled novelty, it is generally a very old story indeed. We still
forget, like children, what happened yesterday. We are still living in a
wonderful new world where man thinks himself astonishingly new and “modern.”
This is unmistakable proof of the youthfulness of human consciousness, which
has not yet grown aware of its historical antecedents." G.G. Jung, from CW Vol. 9.1 Conscious, Unconscious and Individuation
