8 lectures, Oslo, November 25 - December 2, 1921 (CW 79)The lectures in this book remain valid today for a world situation ever more desperate and in need of change based on spiritual-scientific knowledge. The need for developing "consciousness of the self as the spiritual essence of the free, individualistic, single-personality human being" is one of Steiner's unique contributions to the evolving history of humankind. This book marks a real milestone on that path.Self-consciousness is a translation from German of Die Wirklichkeit der höhren Welten (GA 79).
