Best known for his work Being and Time, Martin Heidegger has been hailed by many as the greatest philosopher of the twentieth century. He has also been criticized for being both nearly unreadable and a Nazi. Yet there is no disputing his seminal place in the history of Western thought.

Should we even read the works of a Nazi? John and Ken are present and ready with Thomas Sheehan from Stanford University, author of Making Sense of Heidegger: A Paradigm Shift.
