Third Lecture

And so one can really be, I would say, a very conscientious skeptic about what spiritual research, which I represent, says otherwise. It says that one can come to a kind of exact clairvoyance, an exact examination of this supersensible. I have described how to examine the supersensible exactly in my book, which has been translated into English as Initiation. It is precisely through such investigations of the supersensible that one comes to the conclusion that what no longer follows the physical laws of nature, but is actually a kind of artistic activity in nature, that one pursues these plastic, these plasticizing forces, which are primarily active in the human head organism, and which form those material entities in this head organism that would otherwise be driven outwards as excretory impulses.
