13 lectures in Berlin and Cologne, Oct. 11, 1906-Apr. 26, 1907 (CW 55)Human life is full of mysteries. Why do we suffer? What is evil? What becomes of us after death? What is our origin?Without answers to such questions, our life can seem to lack purpose and meaning. Materialistic science today cannot answer these questions satisfactorily, but Spiritual Science does. In this collection of thirteen lectures, Steiner focuses the light of higher states of consciousness on these pressing concerns of the soul. The resulting suprasensory knowledge gives one's soul the surety and confidence that comes with true knowledge. This volume is a translation of Die Erkenntnis des bersinnlichen in unserer Zeit und deren Bedeutung f r das heutige Leben (GA 55).
