The Fallen Spirits' Influence in the World
Dornach, 27 October 1917
In these 14 lectures, given at the end of 1917 following four years of war in Europe, Steiner speaks on the complex spiritual forces behind the Great War, humanity's attempts to build theoretically perfect social orders, and the many divisions and disruptions that would continue to occur on earth in our time. Humanity in general was asleep to the fact that fallen spirits, cast out of the spiritual worlds, had become intensely active on earth. This manifested particularly in people's thinking and in their perception of the world about them. But the defeat and fall of these spirits also ensured that a science of the spirit would always be available to humanity.
