The remarkable discussions in this volume took place between Rudolf Steiner and workers at the Goetheanum, Switzerland. The varied subject-matter was chosen by his audience at Rudolf Steiner's instigation. Steiner took their questions and usually gave immediate answers. The astonishing nature of these responses - their insight, knowledge and spiritual depth - is testimony to his outstanding ability as a spiritual initiate and profound thinker. Accessible, entertaining and stimulating, the records of these sessions will be a delight to anybody with an open mind. In this particular collection, Rudolf Steiner deals with topics ranging from elephants to Einstein. He discusses, among other things, ants and bees; shells and skeletons; animal and plant poisons - arsenic and lead; nutrition - proteins and fats, potatoes; the human eye and its colour; fresh and salt water; fish and bird migration; human clothing; opium and alcohol; thinking, and bodily secretions.
