IV. Effects of Substances in the Cosmos and in the Human Body

Think of a baby: it kicks a lot and certainly dreams; but it has neither independent thought nor any free will in the real sense. In the measure that it attains freedom of will, its instincts call for iron. Iron is really necessary for free will. And if you come across a man who is hoarse or has a very weak voice and you want to know what is really the cause of it, you must above all find out if he is getting enough iron, for a man who gets too little iron shows this in the lack of will as expressed in speech. When you come across a man who can literally bellow when he is talking, you need not worry whether he is getting enough iron. But in the case of a man who can hardly make himself heard, you are perfectly right to consider how far iron is lacking. Man's need of iron for his free will is shown outwardly. We can therefore easily understand that the iron which is everywhere present in the universe and in the earth is connected with man's free will.
