Post-Structuralist Heidegger

"Heidegger has said it: 'it is not we who speak language, it is language who speaks us'. It structures our world, it structures our sense of time, of identity, of human relations, of love, of violence, and so on. And so, when Foucault, very, very radically... and brilliantly says: 'there is no more man, there is no more author, etc, etc', when deconstruction speaks of language as an autonomous inward turning game as a dance around an infinity of possible meanings, these are ... footnotes to Heidegger.", George Steiner

It's a century long puzzle... Saussure, Husserl, Heidegger, Levi-Strauss, Sartre, Barthes, Foucault, Deleuze, Derrida...
