Publisher's Note

The lectures in this volume were given by Rudolf Steiner at different points in his lifetime. At the time when the earlier lectures were given, Rudolf Steiner was still actively participating in the German Section of the Theosophical Society and was using the terms “theosophy” and “theosophical,” although often in the sense of the anthroposophical science of the spirit presented by him from the beginning. In accordance with a suggestion he made later, after forming the Anthroposophical Society, these designations for the most part have been replaced by “anthroposophy” and “anthroposophical,” except in instances where he is referring historically to the theosophical movement.
