Another special mood is not at all prone to ponder whether behind the phenomena there is still this or that, as is done by the Gnostic mood, or the idealistic or voluntary moods, but which simply says: “I will incorporate into my world-conception whatever I meet with in the world, whatever shows itself to me externally.‿ One can do this in all domains — i.e. through all mental constellations. One can do it as a materialism who accepts only what he encounters externally; one can also do it as Spiritist. A man who has this mood will not trouble himself to seek for a special connection behind the phenomena; he lets things approach and waits for whatever comes from them. This mood we can call Empiricism. Empiricism signifies a soul-mood which simply accepts whatever experience may offer. Through all twelve constellations one can be an empiricist, a man with a world-conception based on experience. Empiricism is the fourth psychic mood which can go through all twelve constellations.
