Austrian philosopher, playwright, and artist Rudolf Steiner (1861–1925) is perhaps best known as an educational philosopher and reformer, the founder of Steiner (or Waldorf) schools located around the world. These schools' philosophy represents the priorities Steiner discusses in Theosophy: the development of body, soul, and spirit. Goethe was an important influence on Steiner, and he edited the poet's scientific works (1889–1896). Steiner was an active member and leader of the German branch of Madame Blavatsky's Theosophical Society, eventually broke away from theosophy, as he developed his own spiritual philosophy termed 'anthroposophy'; this philosophical movement asserted the potential of realizing a spiritual reality through cognition. This 1910 translation by Elizabeth Douglas Shields is of the book's third German edition; it was first published in 1904. This work will be of particular interest to historians of philosophy, of spiritual movements and of education.
