V. Connections Between Organic Processes and the Mental Life of Man

Since the human being as a whole stands in a relation with the outer world, you can readily realize that the lungs have a particular relation to the outer world in connection with the earth element, and the liver in regard to the watery element. If you examine the earthly qualities of plants you will find in them the remedies for diseases which originate in the lungs. (This is of course to be considered in its broadest implications.) If you take what circulates in the plant, its circulation of juices, you will have the remedy for all disturbances connected with the liver. Thus a study of the reciprocal relation of the organs with the outer world offers in fact the foundation for a rational therapy.
