Drawing on Heidegger's corpus, the work of historians and biblical specialists, and contemporary philosophers like Levinas and Derrida, Zarader brings to light the evolution of an impense-or unthought thought-that bespeaks a complex debt at the core of Heidegger's hermeneutic ontology. Zarader argues forcefully that in his interpretation of Western thought and culture, Heidegger manages to recognize only two main lines of inheritance: the "Greek" line of philosophical thinking, and the Christian tradition of "faith." From this perspective, Heidegger systematically avoids any explicit or meaningful recognition of the contribution made by the Hebraic biblical and exegetical traditions to Western thought and culture. Zarader argues that this avoidance is significant, not simply because it involves an inexcusable historical oversight, but more importantly because Heidegger's own philosophical project draws on and develops themes that appear first, and fundamentally, within the very Hebraic traditions that he avoids, betraying an "unthought debt" to Hebraic tradition.

Phusis, Aletheia, Khreon, Moira, Logos: tels sont les Grundworte, ces paroles fondamentales qui inaugurerent notre destin, et dont Heidegger devoile le double statut: ouvrant le commencement, elles abritent l'origine; donnant le branle a l'histoire manifeste de la pensee, elles restent en meme temps porteuses de son versant secret, et toujours oublie. C'est ce versant secret qui est ici explore, faisant de ce livre la patiente reconstitution du texte de l'origine. Texte essentiel, puisque ce n'est que lorsqu'il est retabli que notre histoire, enfin rendue a elle-meme, peut trouver sa cloture; que la question de l'etre, enfin pensee comme question, peut etre abandonnee. C'est dire que l'oeuvre heideggerienne connait un double tournant: le premier permet a la pensee de s'engager dans la question de l'etre comme histoire; le second lui permet de se degager de cette meme question, et de clore l'histoire. De ces deux ruptures, l'une precoce et assez generalement reconnue, est celle de la Kehre, l'autre, tardive et plus meconnue, est celle de l'Ereignis.
