The aim of this paper is to analyze those passages of the Black Notebooks where Heidegger mentions Søren Kierkegaard and to see how Heidegger interprets Kierkegaard’s impact on his own philosophical thought. The paper intends to clarify whether, and to what extent, Heidegger’s rejection of an existentialist reading of his early thought is plausible and justified. The conclusions reached will be twofold. First, Heidegger tries to reinterpret his existential analytic by using the approach he has developed in his work after (...) Being and Time. In so doing, Heidegger tries to understate or diminish the Kierkegaardian background of his analytic of existence. Second, Heidegger’s retrospective self-interpretation argues for a continuity between the approach he develops in Being and Time and that which he calls the question of ‘the truth of beyng’. In so doing, he does not recognize the inconsistencies and mismatches that characterize his thought during the transition from the existential analytic to the philosophy of the event. The passages dealing with Kierkegaard in the Black Notebooks are important sources that allow us to note how problematic Heidegger’s self-interpretation is. (shrink)
