Speaking in the aftermath of the Great War, Rudolf Steiner presents a series of extraordinary lectures on the power and mission of the Archangel Michael. He paints on a broad canvas - in the context of cosmic and human evolution - revealing Michael's tasks in the past, present and future. Rudolf Steiner describes how humanity faces three dangers in the social sphere: spiritual life could flow into the 'pit of mendacity' ruled by Ahriman, individual rights might descend into the 'pit of selfishness' (Lucifer), and economics into cultural sickness and death (Asuras). In order to prevent European-American culture from perishing, it will be necessary to turn towards contemporary 'threefold' social ideas. Steiner also speaks about the principle of metamorphosis in connection with evolution and devolution, as evident in the design of the pillars in the newly-built Goetheanum.
