Principles of Spiritual Science

Principles of Spiritual Science

This challenging volume supports and extends the basis of Rudolf Steiner’s philosophical and anthroposophical thinking. Students who are looking for a secure foundation in the spiritual realities spoken of by Steiner will find in this little book a continuing source of inspiration and encouragement. Rudolf Steiner had asked Unger to continue the work Steiner had done on a spiritual scientific theory of knowledge. This volume is the essence of that lifelong effort. Here Carl Unger writes on human nature and the I; natural and spiritual science; and the “philosophy of contradiction” with which we are continually faced.

About the Author

Carl Unger (1878-1929) was born near Stuttgart. His family provided him with a strong background in science and mathematics, which led him to become an engineer and manufacturer. In 1904, he met Rudolf Steiner and soon became a personal student, lecturing extensively on Anthroposophy from 1907 until 1914, when the Goetheanum building began and, as member of the board of the Anthroposophical Society, he assumed the task of overseeing the construction of the Goetheanum in Dornach, Switzerland, until he was prevented by World War I. He resumed his extensive lecturing until he was killed by a gunman in Nuremberg. He was the author of several books on Spiritual Science, including The Language of the Consciousness Soul, a concise study guide to Steiner’s “Leading Thoughts”; Steiner’s Theosophy: Notes on the book “Theosophy”; and Principles of Spiritual Science.
