Your favorite occupation? Pondering and musing.Your idea of happiness? Pondering and musing.Your most extreme aversion? Pedantry and a sense of order.Of what are you afraid? Punctuality.These quotations are from a questionnaire filled in by a young man in his late twenties. That person, Rudolf Steiner, would later initiate Spiritual Science, or Anthroposophy, and the many practical disciplines that arose from it. Eventually, he would write his Autobiography: Chapters in the Course of My Life, although its completion would be interrupted by his unexpected death. This book is an essential complement to Steiner's unfinished Autobiography. It gathers a wealth of personal testimonies―including lectures, résumés, notebook entries, a questionnaire, as well as biographical notes written for Édouard Schuré―much of which has not been previously published in English. The various materials, together with rare photographs, have been expertly collated and introduced by Walter Kugler.See also the comprehensive biography by Christoph Lindenberg, Rudolf Steiner: A Biography.
