Lecture III

And so I could give you many details to show that the insight into the nature of man which is gained by anthroposophical research builds the bridge between pathology and therapy. For how, in the last resort, do the Ego and astral organisms work? They destroy. And because of this destructive process we are beings of soul and spirit. When something is being disintegrated, a purely poisonous activity is taking place and that destroys the organs. If an organ becomes rampant or hypertrophied, we must disintegrate it. The disintegrative activity belongs to the astral body and Ego. Poisons in an external form—they may be either metallic or vegetable poisons—are, in their effect upon the human organism related to the astral body and Ego. We must realise to what extent a poisonous process is taking place in the human organism inasmuch as the Ego and astral body are at work. There is a correspondence between the budding and sprouting forces of the plants—which we eat without harm—and the physical and etheric forces in the human being; and we must learn to recognise the correspondence between the activity of the Ego and the astral body upon the human organism and the working of the forces and substances of those plants which we cannot eat because they are harmful but which, because they resemble the normally destructive processes in man, can work as remedies.
