The remarkable discussions in these two volumes took place between Rudolf Steiner and workers at the Goetheanum, Switzerland, who chose the varied subject matter. Steiner took questions and usually gave immediate answers. The astonishing nature of his responses, their insight, knowledge and spiritual depth, is testimony to his outstanding ability as a spiritual initiate and teacher.
Accessible and stimulating, the records of these sessions are both entertaining and profound. In From Comets to Cocaine, Steiner discusses, among other things, nicotine and alcohol; the causes and timing of illness; pregnancy; vegetarian and meat diets; the human ear, eye and hair color; influenza, hay fever, hemophilia; 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.
