Lecture VII

These forces are still unknown to external natural science, which is only beginning to surmise them. Science, however, is on the way and one day will reveal these forces by purely external methods. Indeed, there are already exceptions to the statement that the forces leading man out beyond the animal nature are ordinarily unobservable in him. When science once learns to distinguish these forces in man it will discover in the sleeping human body the physical evidence of man's transcending the animal kingdom. When it distinguishes the regenerative forces in man from what is present in the animal kingdom also, it will recognize how the creative forces active in the earth's life to raise man beyond the animal are awake only when man sleeps. From all this we can gather that in self-knowledge man's creative forces, the real human forces, can only be perceived by man when he becomes clairvoyant during sleep; that is, when in a condition otherwise like sleep he awakes clairvoyantly. In the fifth lecture we already indicated this fact.
