Thus Rudolf Steiner presented the threefoldness here quite differently than in Germany and showed new perspectives of this topic. A First English Edition, translated from the original German by Nesta Carsten. Nine public lectures, held between March 11th and November 10th 1919 in Basel, Bern, and Winterthur.
