Speaking towards the end of the catastrophic Great War, Rudolf Steiner reveals the spiritual roots of the crises of our times. Since 1879, he says, human minds have been influenced by backward angels, 'spirits of darkness', who - following their defeat in battle with Archangel Michael - were forced out of the heavens and 'fell' to the earth. This war in the spiritual worlds had consequences, and it is essential that people today are sufficiently awake to the retrogressive influences around them. In a positive sense, we can choose freely to engage with the spirits of light, who seek to emancipate human beings from bonds of race, nation and blood. In this extraordinary series of lectures, Rudolf Steiner throws light on hidden aspects of world affairs. With the Bolshevik Revolution having just taken place, he discusses events in Russia and humanity's attempts to build theoretically perfect social orders. Steiner also speaks about the roles and spiritual backgrounds of significant individuals, such as the mystics Johann Valentin Andreae, Vladimir Soloviev and Saint-Martin, the American and British politicians Woodrow Wilson and Lloyd George, and world-historic figures including Charles Darwin and Johann Wolfgang von Goethe. The new edition of this classic work features a revised translation, notes and extensive appendices by editor Frederick Amrine, plus a new introduction by Christopher Schaefer.
