The Karma of Untruthfulness, Volume Two (Lectures Section)

Out of his research into the spiritual impulses of human evolution, Steiner reveals the dominant role secret brotherhoods played in the events culminating in World War One, and warns that the retarding forces of nationalism must be overcome if Europe is to find its new destiny. He emphasizes the urgent need for a new social structure to emerge out of the insight of spiritual science if humanity is to progress into the future with confidence. This volume is a continuation of Karma of Untruthfulness, Volume One.
