This title was first published in 2002: 'I sincerely believe that Dr Kolnai is one of the most original and stimulating thinkers in the field of political philosophy alive today.' Karl Popper Kolnai's moral and political thought was developed against the background of Liberal and then Bolshevist revolutions in Hungary, the gradual move towards fascism in twenties and thirties Vienna, and the progress of the Second World War as seen from the USA. Born a Jew, he became a Roman Catholic, and lived successively in Hungary, Austria, France, the USA, Canada and England. He remained, throughout his extraordinary life, a passionate believer in reason and common sense, and the sworn enemy of all philosophical and political systems. Study of Kolnai has been hampered by political developments, his own peripatetic life, and the fact that his writings appeared in five different languages, yet interest in Kolnai is now growing. This book offers the first comprehensive picture of Kolnai's complete works and life. Dunlop presents Kolnai the man in his social and political setting, and offers an accessible exploration of all his writings, whether published or not, including translated passages from papers and letters in Kolnai's various languages. Including a selective bibliography of Kolnai's works, this book presents an important study of this unique political and moral philosopher, showing his relevance in contemporary philosophical thought.
