Late Heidegger is characterized by the way he went from a resolute sort of grasping of things to a kind of openness and so forth.
The Late Heidegger is a shift form asking the question of Being from the perspective of Dasein, to asking it from the perspective of Being.
Late Heidegger is uniquely interested in thinking Being historically, in showing how things showed up differently or the Greeks (heroes), or or the Christians (saints and sinners), or or us moderns (anxiety and technological nihilism).
The Late Heidegger is a subtle reformulation of the question of Being itself. The question now becomes not ‘What is the meaning of Being?’ but rather ‘How does Being essentially unfold?’
The Late Heidegger is a transition in focus from Dasein's distinctive mode of Being which is identified is temporality to a shift in focus to the claim that human Being consists most fundamentally in dwelling.
