The etymology of ‘truth’ by Martin Heidegger
The etymology of ‘truth’ as ‘revelation’ and ‘exit from oblivion’ is not a contribution by Martin Heidegger: he just received this from the Greeks (which he said en passant, yet without specifying his sources), particularly from Damascius (which Heidegger did not say).
