Abstract
The paper focuses on the problematic pattern of the Black Notebooks in a crucial and dramatic period of Heidegger’s course, that is the one between the thirties and the forties of the last century. In particular, Heidegger’s relationship with National Socialism will be outlined and the interpretation of World Judaism and modern Christianity as a figure of nihilism, namely that of fulfilled metaphysics. From the implication of these three elements, the fundamental feature of the Notebooks can thus be found. This critical reconstruction aims to survey the trend, which is widely present in the philosophical literature of the last decades of the XXth century, of a post-metaphysical and post-Christian image of Heidegger’s thought. The paper intends to replace the core of the unsolved tangle of his thought: the broken confrontation with modernity and his clinch with the Cristlichkeit. It could be said that what appeared to be solved to him was the possible future of his presence in the philosophy of our time.
