Lecture V

I have a few things to add to the four lectures on freedom and necessity which more or less form a connected whole. Let us take another look at one of our basic truths of spiritual science, the structure of the human being that we have become so well acquainted with. We consider man as a synthesis of four members: the physical body, the etheric body, the astral body and the I. If we confine ourselves to what is in the physical world, to the part of the human being that is given, we can state that in our ordinary waking condition we have in the first place the physical body. We know our physical body for the very reason that we can obviously observe it externally with our senses, and everyone else in the physical world can observe it in the same way and has to agree with us that the physical body exists. Therefore, in the physical world this physical body can be perceived from outside.
