How else could it have occurred to man to divide the cosmos, on the analogy of day and night, summer and winter, into a bright day-world and a dark night-world peopled with fabulous monsters, unless he had the prototype of such a division in himself, in the polarity between the conscious and the invisible and unknowable unconscious?

It is only through the psyche that we can establish that God acts upon us, but we are unable to distinguish whether these actions emanate from God or from the unconscious.
