II. Nutrition

But you can see from this that spiritual science, as practised here, recognizes precisely the right kind of materialism. Materialism knows nothing at all about the material; spiritual science recognizes precisely that the potato is the right producer of materialism. It is terribly insidious, the potato, cunning, clever to excess. For just see, man can only eat the tubers of the potato, not even the eyes on the potato – they are harmful in themselves – and he certainly cannot eat the flower, because the potato is a member of the nightshade family and the flowers are poisonous. But what is the poison? I already told you last time: in large quantities the poison kills, in small quantities, finely distributed, it is a remedy. The potato itself has a great deal of starch paste in it, it consists almost entirely of starch paste. It could not live because the starch paste would be terribly harmful; at the same time, it draws the poison out of the world and destroys the harmful effect in itself. That is why I call her clever and cunning. She herself has her poison, through which she removes the harmfulness for herself. But the poison of the potato is particularly harmful to humans; she does not give that to him, she only gives him what she herself combats in herself through her poison. It is really something that can be called that: the potato is a clever, cunning creature! And humans must be clear about the fact that if they eat too many potatoes, their midbrain will atrophy and that even their senses can suffer precisely from excessive potato consumption.
