This is a film about Ludwig Wittgenstein and Arnold Schoenberg; two men whose lives and ideas run parallel in the development of Viennese radicalism. Both men emerged from the turmoil of the Habsburg Empire in its closing days with the idea of analyzing language and purging it with critical intent, believing that in the analysis and purification of language lies the greatest hope that we have. They never met and might never have fully understood one another, because while the nature of their genius they found themselves alone breaking new ground of the very frontiers of their respective disciplines. But their work springs from the same soil and shares a common ethical purpose, so that their ideas and methods echo and illuminate those of each other to a remarkable degree.
