Rudolf Steiner's Lectures

Rudolf Steiner’s lectures form the largest portion of his Collected Works, with over 6,000 lectures delivered between 1900 and 1924 across Europe. These transcribed and translated lecture cycles address virtually every domain of human inquiry — from spiritual science to practical applications in medicine, agriculture, education, and the arts. This section gathers approximately 500 editions available in English translation.

Key cycles include the Karmic Relationships series (GA 235–240), the Agriculture Course (GA 327), and the Faculty Meetings with Rudolf Steiner (GA 300a–c). Lectures range from intimate esoteric lessons given to members of the Anthroposophical Society to large public addresses in cities such as Berlin, Vienna, and Stuttgart. Translations by George and Mary Adams, A. H. Parker, and Johanna Collis ensure fidelity to the original German stenographic records.

Whether you are a seasoned student of anthroposophy seeking a particular lecture series or a newcomer drawn to a specific subject, this collection provides direct access to Steiner’s own voice. The Introductory & Fundamental Works subcategory offers recommended starting points.
