This progressive assimilation of unconscious contents gradually builds up the personality, thus creating an enlarged psychic system which forms the basis of man's inner spiritual history as this makes itself increasingly independent of the collective history going on all around him.  This process, initiated in the first instance by philosophy, has today reached what is chronologically its latest stage in psychology, still of course only in its infancy.  Hand in hand with this there goes a 'psychization' of the world.  Gods, demons, heaven and hell are, as psychic forces, withdrawn from the objective world and incorporated in the human sphere, which thereupon undergoes a very considerable expansion.  When we give the name of 'sexuality' to what was once experienced as a chthonic divinity, or speaking of 'hallucination' instead of revelation, and when the gods of heaven and the underworld are recognized as dominants of man's unconscious, it means that an immense tract of external world has dropped into the human psyche.  Introjection and psychization are on the other side of the process by which a world of physical objects becomes visible, and this world can no longer be modified by projections to the degree that it could before.
