The book "On the History and Contents of the First Section of the Esoteric School, 1904-1914" by Rudolf Steiner offers a deep insight into the beginnings of the Esoteric School he led. This institution, which existed from 1904 to 1914, was a significant part of the occult movement and was interrupted by the First World War. The present volume gathers all relevant documents from the first section and addresses topics such as the history of the school's formation, the methodology of free esotericism, and the division of the Esoteric School into Eastern and Western currents. Additionally, the book includes transcripts and notes from lectures that illuminate the relationship between the movement, the Esoteric School, and society. A comprehensive index rounds off the content and allows for targeted research.
