Prefazione [a Il pensiero di Heidegger nei trattati inediti. Natura, verità e tecnica a partire dall’Ereignis]

Martin Heidegger's unpublished treatises constitute the “laboratory” for the definition of “Ereignis”. Heidegger develops the ideas of “Natur”, “Technik” and “Lichtung”, which are central to understanding Ereignis as a transition from the first beginning to the other beginning of “Seinsgeschichte”, comparing them with the Greek concepts of “phýsis”, “téchne” and “alétheia”. The content of the unpublished treatises can be understood on the basis of Heidegger's contemporary lectures and works published in the 1930s and 1940s.
