Lecture IV
Man is a twofold being. On the one side, we have what may be called man's lower nature—the word leads to misunderstandings, but there are few words in our language that adequately express what one would like to convey from the spiritual-scientific standpoint—namely, the physical, corporeal organization of which he consists in the first place. I have described the latter to you in my last lecture in connection with the sense organization. Today, we shall not go into that but refer to it again tomorrow. Those of you, however, who have studied anthroposophical literature to any extent at all, have some idea of man's physical, bodily organization and know that it is connected to the surrounding environment. What constitutes the outside world and dwells out there in the mineral, plant and animal kingdoms, also constitutes us human beings in the physical, corporeal sense. In a way we are its concentration, elevated to a higher level, and figuratively one could say that we are the crown of creation. In the physical, bodily sense we are a confluence of the effects of forces and substances occurring outside and appearing before us through our sense perceptions.
