Richard Seddon draws together the essence of hundreds of lectures to create this broad overview of Rudolf Steiner's spiritual research into the course of human evolution. His fascinating survey takes us from the present to the far-future stages of our planet. He also discusses the respiritualization both of the earth and of the whole solar system, which were not mentioned by Steiner but throw considerable light on events in the Apocalypse and on the eventual transforming of evil to good.
