The Austrian philosopher and writer Rudolf Steiner was one of the most original thinkers of the 20th century. His writings cover a wide range of subjects, and he made valuable and influential contributions in many fields, including education, science, medicine and social reform. The basis of his researches was the science of the spirit which he called anthroposophy. He maintained that material science could never comprehend the whole of nature as it excluded the realm of the spirit. Bridging between the physical and spiritual worlds, anthroposophy would show the way towards a true understanding of humanity and its relation to the universe. This book is a concise illustrated introduction to Steiner's life and work, describing how many of his ideas have been put into practice, and are still giving inspiration and guidance to many people all over the world.
