After Rudolf Steiner had left us in the body, the gifts of the spirit that were offered by him in such overflowing measure could not continue. It must now happen that a community of human beings takes over the results of his spiritual research, takes them in such a way that they remain alive in the community. People must come together in anthroposophic work, united in such a way that Anthroposophy comes into its own. –Carl Unger (lecture in Stuttgart, Oct. 29, 1928)This volume provides perhaps the most comprehensive and profound exegesis of Rudolf Steiner’s Anthroposophy, especially his book titled Anthroposophical Leading Thoughts. That book provides Steiner’s final and most complete explanation of his Spiritual Science through brief, aphoristic thoughts, or meditations, on the profound esoteric meaning of the modern spiritual path he called Anthroposophy. In The Language of the Consciousness Soul, Carl Unger unfolds and expands Rudolf Steiner’s leading thoughts to help the reader comprehend the deeper meaning behind the words. Unger lets us see how Rudolf Steiner created a mandala-like image of Anthroposophy, revealing an ever-expanding cosmology and epistemology that goes far beyond mere philosophy or a belief system to a practical path of spiritual investigation and knowledge for modern humankind. Rudolf Steiner had this to say about Carl Unger: Dr. Carl Unger, for many years past, has always been the most industrious and devoted collaborator in the anthroposophic movement…At an early date, Dr. Unger saw that Anthroposophy, before all, needs a strong foundation of the theory of knowledge. With a deep understanding he took up what I myself, many years ago, was able to give in my books Goethe’s Theory of Knowledge, Truth and Knowledge, and Intuitive Thinking as a Spiritual Path: A Philosophy of Freedom, he developed independently what I had intimated. Supported by mental discernment, his goal was to see through the nature of the human process of knowledge in a clear analysis, and from that to form its true picture. Dr. Unger is not dialectical but an observer of empirical facts. This is why, through the years, he has been able to give results of the highest value, showing how the process of knowledge in ordinary consciousness produces, always and everywhere, out of itself, the impulses to anthroposophic investigation. Moreover, Dr. Unger’s method of thinking, trained through technical problems, is free from subjective vagueness, and thus his scientific collaboration in Anthroposophy is the most important that we can have. The Language of the Consciousness Soul is an indispensable guidebook for group study and for individuals who wish to penetrate the depths of Anthroposophy and apply its principles both inwardly and to outer daily life.
