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.
