Rudolf Steiner, the often undervalued, multifaceted genius of modern times, contributed much to the regeneration of culture. In addition to his philosophical teachings, he provided ideas for the development of many practical activities including education--both general and special--agriculture, medicine, economics, architecture, science, religion, and the arts. Today there are thousands of schools, clinics, farms, and many other organizations based on his ideas. Steiner's original contribution to human knowledge was based on his ability to conduct spiritual research, the investigation of metaphysical dimensions of existence. With his scientific and philosophical training, he brought a new systematic discipline to the field, allowing for conscious methods and comprehensive results. A natural seer from childhood, he cultivated his spiritual vision to a high degree, enabling him to speak with authority on previously veiled mysteries of life. Topics include: the evolving human being; cosmos as the source of life; plants and the living earth; farms and the realms of nature; bringing the chemical elements to life; soil and the world of spirit; supporting and regulating life processes; spirits of the elements; nutrition and vitality; responsibility for the future.
