'Anthroposophy is a path of knowledge, to guide the Spiritual in the human being to the Spiritual in the universe.' (From the first 'Leading Thought'.) This key volume contains Rudolf Steiner's so-called 'Leading thoughts' and 'Letters' written for members of the Anthroposophical Society. In brief paragraphs, they succinctly present Rudolf Steiner's science of the spirit, Anthroposophy, as a modern path of knowledge. Invaluable as clear summaries of Rudolf Steiner's fundamental lines of thought, they are intended not as doctrine, but as a stimulus and focus for study and discussion. Their intention, as Rudolf Steiner states, is to contribute to a 'unity and organic wholeness of the work of the Society without there being any question of constraint'
