Rudolf Steiner was active at the beginning of the 20th century as the founder and leader of the anthroposophical movement, which developed out of his teachings and insights. His oeuvre comprises over 6,000 lectures and dozens of written works. David Eyes is a lifelong student of anthroposophy and has served for a number of years on the core group of the Anthroposophical Society branch where he lives in Santa Cruz, California.
