Sixth Lecture
What does this change of conditions mean for our earth? Let us say, for example, that spring is coming. When spring comes, it means that the sun's effect on the earth is quite different from that during the winter. We could also say: When spring arrives, the earth is seized by the effects of the sun. During the winter, when our little earth with the great earth was, so to speak, dependent on itself, when the sun did not care about our little earth, now our little earth is also seized by the effects of the sun, by what is outside of our earth. The sum of forces in the little earth is snatched from the earth. Our little earth is, so to speak, no longer dependent on the earth alone; it is claimed by the sun, it is snatched from the earth. Yes, when our little earth is snatched from the earth in this way, then other forces than mere earthly forces play into our little earth, then the external forces communicate with our little earth.
