Two lectures in Bologna: on 31 March 2011 at the International Conference to Mark the Centenary of Rudolf Steiner's Lecture in Bologna, and on 8 April 1911 at the Fourth International Philosophy Congress A special conference took place in Bologna in Spring 2011, marking the hundredth anniversary of a unique lecture Rudolf Steiner delivered to a philosophically-trained audience in the same city.In his key exposition, Steiner had given a concise description of the spiritual-scientific theory of knowledge as well as a brief outline of the anthroposophical path of schooling. In his contribution to the 2011 congress, Sergei O.Prokofieff tackles two principal aspects. On the one hand, he describes how Steiner's Bologna lecture contained the essential foundations for a new 'science of the human ego'.On the other hand, Prokofieff states that Rudolf Steiner was the first person to transform this same theory into a practical path of knowledge, following it to its very conclusion.Thus, the words of Rudolf Steiner's lecture were based entirely on personal experience.Together with a transcript of Rudolf Steiner's full Bologna lecture, Sergei O. Prokofieff's own lecture is reproduced here in an expanded version.In addition, this volume features Rudolf Steiner's important 'summaries of essential points', in which he develops and connects some of his key thoughts with further aspects of anthroposophy, especially in relation to their Christological foundations.
