Rudolf Steiner (1861-1925) was an Austrian philosopher, writer, and lecturer, and the founder of anthroposophy, a system of thought that integrates spiritual and philosophical inquiry. His work spans a wide range of subjects, including education, agriculture, medicine, and the arts, reflecting a comprehensive approach to the relationship between human development and the world.Steiner's writings and lectures present a method for understanding both the material and spiritual dimensions of experience, often emphasising the role of disciplined thought and perception. How to Know Higher Worlds is among his most widely read works, outlining a structured approach to the development of inner awareness. His influence extends across multiple fields, and his work continues to be studied for its scope and its integration of philosophical and spiritual ideas.
