Martin Heidegger is one of the most influential philosophers of the 20th Century, and a key philosophical resource for literary critics. Not only has he written about poetry, generations of poets have engaged his writings. And yet, for Heidegger poetry and literature are separate. An essential part of the project of this book therefore is to show how both the distinction and connection between literature and poetry is staged within Heidegger's thought. It offers Heidegger's perspective on a range of key themes, topics, poets, and writers, including Poetry and Poetics, Ancient Greek theatre and tragedies and then specifically Friedrich Hoelderlin, Thomas Mann, Paul Celan, Euripides and Sophocles. As the Chapters comprising this book make clear, Heidegger's work remains indispensable for any serious engagement with either literature or poetry today.
