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 anyone with an open mind. In this particular collection, Rudolf Steiner deals with topics ranging from comets to cocaine! He discusses, among other things, nicotine and alcohol; the causes and timing of illness; pregnancy; vegetarian and meat diets; the human ear, eye and hair colour; influenza, hay fever, haemophilia; planets and metals; mental illness; the ice age; the thyroid gland and hormones; beavers, wasps and bees; the nose, smell and taste; and jaundice, smallpox and rabies.
