For more than four decades Josef Simon has given important impulses to philosophy which have attracted much international attention. Often unconventional in presentation, his works on Kant, Hegel and Nietzsche, on the philosophy of language and signs but also on practical philosophy have repeatedly made fundamental questions of philosophy appear in a surprising new light. The volume, also containing a complete bibliography of Simon's writings, encompasses 18 of Simon's exemplary works from all creative periods and from the central historical and systematic subject areas of his work.
