Heidegger in Ruins examines how the political ideology of National Socialism is deeply woven into the philosophy of Martin Heidegger, a central figure in 20th-century thought. Richard Wolin, the author, delves into Heidegger's key works, revealing his strong ties to the conservative revolution. The publication of Heidegger's Black Notebooks in 2014 exposed the extent to which his philosophical ideas were entwined with a radical vision of the conservative revolution. Heidegger in Ruins highlights the philosophy that was not just influenced by but inherently linked to his political beliefs, challenging the separation between his philosophy and politics. Heidegger in Ruins investigates what this revelation means for Heidegger's legacy and the implications for modern philosophical discourse.
