Heidegger's destruction of Aristotle's ontology in being and time

The focus of my thesis is Heidegger's critical interpretation of Aristotle's ontology in Being and Time. I will juxtapose Heidegger's project of a fundamental ontology, that is to say, his attempt to work out the meaning of being as such, with Aristotle's attempt to ground a science of being qua being and, in so doing, I hope to shed some more light on the raising of the question of the meaning of being (Seinsfrage). I try to show that although Aristotle, in his account of being, did not explicitly raise this question, his ontology nonetheless prepared the ground for Heidegger to raise the Seinsfrage. In the first half of the thesis, I selectively present Heidegger's account of being in Being and Time. My exegesis of the existential analytic of Dasein in terms of temporality will provide the relevant and required background considerations for the argument I present in the latter half of the thesis. I argue that Heidegger's critical remarks in The Basic Problems of Phenomenology concerning Aristotle's interpretation of time are paramount to understanding his critique of Aristotle's interpretation of being in the primary sense as ousia. I place this argument in the wider context of Heidegger's reading of Aristotle in the Introduction, where I provide a narrative account of Heidegger's engagement with Aristotle through a parallel discussion of Heidegger's other key works on Aristotle and the relevant secondary literature. Although it will be impossible to give an exhaustive overview of Heidegger's account of being, or of the entirety of his philosophical consideration of Aristotle, my textual focus, limited by the constraints of an MPhil thesis, will concern those texts of Heidegger's that I deem most helpful for the attainment of my stated aim
