In 1924 Dr Rudolf Steiner gave 8 lectures which have since become known as the 'Agriculture Course'. To many this course was the seed which grew into modern organic agriculture, and certainly into biodynamic agriculture. However, even for those familiar with Dr Steiner's wider work - Anthroposophy - these lectures are very challenging to comprehend and build upon. This commentary by Enzo Nastati shows both a thorough penetration of the subject and offers insight to the developments that Enzo Nastati and his team have built upon Dr Steiner's foundation. In 30 meetings from 2001 to 2005 this was explained to the farmers and gardeners who wished to develop Dr Steiner's work. The revised transcripts have now been translated in English, and promise to assist sincere students of biodynamic agriculture to become more conscious of what Dr Steiner offered 80 years previously.
