Lecture II

I want you now to follow me in a brief train of thought. I am giving it merely by way of example, but it will show you the path that must be followed. Take the annual plant that grows out of the earth in spring and passes through its yearly cycle. Now relate these phenomena that you observe in the annual plant with other things you can observe—above all the custom of peasants who, when they want to keep their potatoes through the winter, dig pits of a certain depth and put the potatoes into them so that they may keep for the following year. If the potatoes were kept in an ordinary open cellar, they would not remain fit to eat. Investigations have proven that what originates from the interplay between the sunshine and the earth is contained within the earth during the subsequent winter months. Warmth conditions and light conditions are at play dynamically under the surface of the earth during the winter, so that in winter the aftereffects of summer are actually contained within the earth. Summer surrounds us outside the earth's surface. In winter, the aftereffects of summer work under the earth's surface. And the consequence is that the plant, growing out of the earth in its yearly cycle, is impelled to grow, first and foremost, by the forces that have been poured into the earth by the sun of the previous year, for the plant derives its dynamic force from the soil. (I have to make rather large leaps, of course, but these things can all be verified easily through empirical observations.) This dynamic force that is drawn out of the soil can be traced up into the ovary and on into the developing seed. So you see, we can arrive at a botany that really corresponds to the whole physiological process only if we do not confine ourselves to the dynamic forces of warmth and light and the light conditions during the year when the plant is growing. We must rather take our start from the root, and so from the dynamic forces of light and warmth of at least the year before. These forces can be traced right up into the ovary, so that in the ovary we have something that really is brought into being by the forces of the previous year.
