Although Heidegger's writings are not extensively concerned with the analysis of political concepts or with advocating particular arrangements of political institutions, his basic way of understanding the human relation to the world accords a constitutive significance to its social, cultural and historical dimensions. There is thus a political aspect to his thinking about every philosophical matter to which he turns his attention. This collection of essays is designed to identify, contextualize and critically evaluate the main phases of his intellectual development from that perspective.
