We find that astrology is the psychology of the ancients projected into the heavens, into the most remote bodies. There are two main principles in a horoscope, the sun and the moon.  The sun has the psychological quality of man’s active nature, the moon of man’s reacting nature.

In his active nature one would designate his character as willed, voluntary. In his reactive nature he is passive, merely responding to stimuli. As a matter of fact, when you meet a man in his lazy hours, as he is at home, for instance, you find that he is quite different from the man in his business hours. They are two different men; astrology would say that one was his sun character and the other was his mooon character.

People having such reactive natures are passive, they are parts of nature in mind or mood. They play parts in which they are surely not the active leaders but more or less the victims, managed by circumstances or by other people, by external and internal stimuli. They are not quite free. They are under a dark law. That is what man feels most in the night, so the moon became the exponent of that side of man’s psychology, quite different from the sun psychology.

And because it is so difficult to deal with, the moon is an appropriate symbol; the contradictions and paradoxes of night psychology fit in well with the moon. As Dr. Harding has pointed out, it is exceedingly difficult to deal with this psychology in rational language. It seems to be violated by that approach. It is as treacherous as moonlight in masking forms. Such a psychology represents an indefinite, peculiar condition of mind where a thing may be so and not so at the same time. All our attempts to define it refer to a condition that is semiconscious, nocturnal.

So when we speak of the unconscious in terms of the moon, we are really talking about the psyche in a semiconscious state, where thing are unclear and contradictory. In the unconscious, opposite things are lying close together.
