Rudolf Steiner (18611925) called his spiritual philosophy 'anthroposophy', meaning 'wisdom of the human being'. As a highly developed seer, he based his work on direct knowledge and perception of spiritual dimensions. He initiated a modern and universal 'science of spirit', accessible to anyone willing to exercise clear and unprejudiced thinking.

From his spiritual investigations Steiner provided suggestions for the renewal of many activities, including education (both general and special), agriculture, medicine, economics, architecture, science, philosophy, religion and the arts. Today there are thousands of schools, clinics, farms and other organizations involved in practical work based on his principles. His many published works feature his research into the spiritual nature of the human being, the evolution of the world and humanity, and methods of personal development.
