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."

According to Kant, all thinking stays bound to the original subject of thinking and its possibilities. Simon describes Kant's work as a system that distinguishes its own particular approach to thought as something special in relation to others. Although the subject does not always understand the thoughts of others, each subject incorporates this 'foreign thought' into its own view of the world. Thus arises the need for finding a language allowing for conveying the own preliminary interpretation of something to others in such a way that the said something becomes meaningful also for them, and in this sense appears to be true for them. At that point, the concept of meaning changes, as does the language of philosophy.
