The founding of the Anthroposophical Society in 1913 marked a major change in Rudolf Steiner's work. Although Steiner had always been an independent spiritual researcher, the break with the theosophists removed all constraints, allowing for a full flowering of anthroposophy. These lectures are filled with a freshness and vitality that reflect this new beginning, providing intriguing glimpses of great themes that Steiner was to develop in the years ahead.
