This vintage book contains a collection of fascinating lectures by Rudolf Steiner. They chiefly concern the goals of spiritual science and the concepts of truth, anger, and reverence. The lectures also deal with the exploration of the human condition, egoism, asceticism and illness, and Buddha and Christ. This volume is highly recommended for those with an interest in philosophy and the work of Rudolf Steiner. Rudolf Joseph Lorenz Steiner (1861-1925) was an Austrian author, philosopher and esotericist. The lectures include: "The Mission of Spiritual Science", "The Mission of Anger", "The Mission of Truth", "The Mission of Reverence", "Human Character", "Asceticism and Illness", "Human Egoism", "Buddha and Christ", and "Something about the Moon in the Light of Spiritual Science". Many vintage books such as this are increasingly scarce and expensive. We are republishing this volume now in an affordable, modern edition complete with a specially commissioned new introduction.
