Alexander Duff has a lengthy piece on the relevance of Heidegger to the current flush of nationalisms rumbling (if not yet sweeping) both the Western world and parts of the non-Western world (“Heidegger’s Ghosts”):
A specter haunts the post-Cold War liberal order—the specter of radical spiritual malaise. This discontent with or downright opposition to the Western-originated, universalist claims of the broadly liberal cultural, economic, and political order takes diverse forms. One can detect it among Iranian revolutionary theocrats, Russian imperialist ideologues, white supremacist “Identitarians,” European neo-fascists, identity-politics partisans, and anti-foundationalist intellectuals of many stripes. But standing behind some of the leading intellectual and political figures in this mélange of counter-liberalism is one animating mind, that of Martin Heidegger…
… Heidegger’s thought, while not lending itself to any politically cohesive opposition to the liberal West in a manner that characterized Marxism, recommends itself to virtually every variety of particularist opponent of Western universalism. For those inspired by Heidegger, the universalist claims upon which the liberal order is based are too thin, too weak, and too ignoble to provide tangible and meaningful sources of human identity.
