In these five talks, Rudolf Steiner laid out the foundations for a truly spiritual psychology. The first two lectures take a critical look at the principles of Freud and Jung’s early work. The last three lectures describe the threefold structure of human consciousness and then outline a psychological approach that considers both the soul’s hidden powers and the complex connections between psychological and organic, bodily processes. Robert Sardello, codirector of The School of Spiritual Psychology, contributed an important and provocative introduction from the perspective of a practicing psychotherapist. Chapters include “Anthroposophy and Psychoanalysis,” parts 1 and 2; “Spiritual Psychology: Subconscious and Supra-conscious”; “Hidden Depths of Soul”; and “Organic Processes and Soul Life.” This is an important work for understanding Steiner’s views on psychoanalytic practices as they appeared in the first quarter of the twentieth century.
