The root of that tree is Rudolf Steiner . In The Scientist of the Invisible, biography meets intellectual history to uncover the life of the most enigmatic figure of the 20th century. Born in a railway station on the edge of the Austrian Empire, Rudolf Steiner (1861–1925) lived a life that defied categorization. He was a scholar who edited the scientific papers of Goethe; a philosopher who debated Nietzschean ethics; a social reformer who challenged the rise of German Nationalism; and a clairvoyant who claimed to read the cosmic memory of the universe. Steiner did not ask his followers for faith. He asked for work . He argued that the split between Science and Spirituality was an illusion—and that with rigorous mental training, the human mind could become an objective organ for perceiving the spirit. This definitive biography reveals: The Making of the Mind: How a "Stationmaster's Son" bridged the world of steam engines and the world of angels. - The Great Schism: The dramatic break with Theosophy and Annie Besant over the true nature of Christ and the identity of J. Krishnamurti. - The Builder: The construction of the Goetheanum , the "House of Speech" built by international volunteers while World War I raged around them. - The Fire: The Nazi-led arson attack that burned his life’s work to the ground—and his defiance in rebuilding it in fireproof concrete. - The Legacy: How his specific insights into agriculture, medicine, and education saved them from the crushing materialism of the industrial age. Part history, part philosophy, and part spiritual detective story, this book moves beyond the rumours and the "guru" myths. It presents Steiner as he saw himself: a scientist of the invisible.
