Steiner gives his most concise and detailed account of human nature in these lectures, which are absolutely essential for anyone who wants a deeper understanding of Steiner’s spiritual science. Those who are willing to work through this work will discover here a new, powerful, convincing, and profoundly phenomenological “anthropology” of human spiritual psychology. In these lectures, Steiner laid out for the first time the principles that form the basis for renewing the art of teaching. The Foundations of Human Experience is the most important text for studying and understanding the human developmental and psychological basis for Waldorf education. Translated from the German editions: Allgemeine Menschenkunde als Grundlage der Pädagogik (GA 239); appendix from Geist und Stoff—Leben und Tod (GA 66). A previous translation of GA 239 was titled Study of Man.
