Lecture II

While humanity lives today as it does, letting authoritative sciences issue from the various establishments, there exists in the spiritual worlds a sacred decree; external science must be supplemented by the science of the knowledge of man' It will be disastrous for mankind if it receives only external science, The Mysteries existed in ancient times in order not to let anything harmful approach man, but that is not compatible with the modern spirit. Mankind therefore in its conscious members must care for what was formerly cared for by outside powers. Those personalities who have come to understand something of these things must take care that the different sciences cannot cast their shadows, by confronting the shadows, which would darken humanity, with the light of a real, genuine, concrete self- knowledge of man. Sciences without this self-knowledge are harmful, for they Ahrimanise humanity-, Sciences with the counterpart of human self-knowledge are beneficial, for they lead mankind in reality to what it must reach in the immediate future. There should be no science which in one respect or another is not brought back to the human being. There should be no science which is not followed up right into the inmost being of man, where, if it is thus followed up, it first acquires its true meaning.
