Third Lecture
Thus we must accept such things, as they have been touched upon today, in such a way that we really say more and more to ourselves: For spiritual science, different human attitudes must be inwardly adopted than those in the culture up to now. There must arise a much greater striving for constant activity among people, for activity, for being there. The idea that one has grasped something and can retain it and carry it through life must disappear. If that disappears, all the other things that stand in the way of clear perception will disappear as well. I have often pointed out how people, even in science, have the most confused ideas about what is true. For example, you will often read in physiological works today that people sleep because they experience this or that in their waking state and become tired from it. Sleep would therefore be a result of fatigue. I have pointed out that the reindeer, which does not need to work very hard, should not have any need for sleep either. But if you listen to the reindeer, you will learn that if you do nothing at all, you feel most tired and you fall asleep without having done the slightest thing. From this you can see that fatigue has nothing to do with sleep, and sleep has nothing to do with fatigue, any more than day has to do with night.
