Why was the act of arson that destroyed the first Goetheanum so devastatingly successful in its malicious intent? What was the nature of the poisoning that Rudolf Steiner suffered in 1923? What was the significance of Steiner's encounter with an unknown Master in 1879, and his later meeting with Friedrich Nietzsche on his sickbed? Rather than presenting an accumulation of data, Meyer takes a symptomatological approach to the evolution of Rudolf Steiner's thinking, pinpointing specific moments in his biography, whilst making numerous links to contemporary issues. Seemingly unimportant details are significant - such as Steiner's boyhood habit of smashing dishes, or the droplet of water that adorned Steiner's forehead at his funeral. The often overlooked language of such images is evaluated within the scope and grandeur of Rudolf Steiner's life's work. An incisive theme running through Milestones is the dual nature of time - 'involution' and 'evolution' - and how it affects the Anthroposophical Society and movement. Following Steiner's death, a one-sided involution process has been evident in the overemphasis on the Christmas Foundation Meeting, as well as Steiner's supposedly 'indissoluble' connection with the Society. This is coupled with distorted evolution processes, as seen in the urge to enter the public domain by jettisoning anthroposophy altogether. Such disharmonies can only be healed, says Meyer, by seeing the reality. This book serves as an essential guide to understanding the task of anthroposophy in the modern world.
