Lecture XIII
But now what about potatoes? Suppose a scientist or a doctor were asked to say what effect potatoes have when they are eaten. As you know, potatoes have become a staple. In some places it is very difficult to dissuade the people from feeding almost exclusively on them. What does the modern scientist do when he tests potatoes for their nutritional value? He makes a laboratory investigation to find what substances are contained in the potato. He finds carbohydrates, which consist of carbon, oxygen, and hydrogen in definite proportions; he also discovers that in the human body these substances are finally transformed into a kind of sugar. But he gets no further than that; nor can he do so. For think of this: if some animal is fed on milk, it may thrive. But if the milk is analyzed for its chemical components and if these chemical components are given to the animal instead of the milk, it will waste away for lack of nourishment. Why is that? It is because something is working in the milk in addition to the chemical components. And in the potato, too, there is something more than the mere chemical components: namely, the spiritual element. A spiritual element works everywhere, in all of nature.
