4. The Human Organism Through the Incarnations
Therefore I would like to ask you to pay attention to what I say about the concept of reality in my new book, Vom Menschenrätsel.[^6] We must develop a concept of reality, and not just a concept of the logical. A crystal is a self-contained reality, complete in itself. When I examine the crystal for what it is, it tells me the truth about itself. But look at a tree trunk without its roots and branches, does it also tell us the truth about itself? No, certainly not; it is telling lies as it is lying there, for it cannot exist as a tree trunk by itself. It could never exist if it did not grow in connection with roots, branches, and leaves; all these belong to the tree trunk. I find the truth about it only if I picture the tree as a whole. With the trunk by itself I have a piece cut out of the world of the senses, but this fragment is not a reality.
