  At root Heidegger's later philosophy shares the deep concerns of Being and Time, in that it is driven by the same preoccupation with Being and our relationship with it that propelled the earlier work. In a fundamental sense, then, the question of Being remains the question. However, Being and Time addresses the question of Being via an investigation of Dasein, the kind of being whose Being is an issue for it. As we have seen, this investigation takes the form of a transcendental hermeneutic phenomenology that begins with ordinary human experience. It is arguable that, in at least one important sense, it is this philosophical methodology that the later Heidegger is rejecting when he talks of his abandonment of subjectivity. Of course, as conceptualized in Being and Time, Dasein is not a Cartesian subject, so the abandonment of subjectivity is not as simple as a shift of attention away from Dasein and towards some other route to Being. Nevertheless the later Heidegger does seem to think that his earlier focus on Dasein bears the stain of a subjectivity that ultimately blocks the path to an understanding of Being. This is not to say that the later thinking turns away altogether from the project of transcendental hermeneutic phenomenology. The project of illuminating the a priori conditions on the basis of which entities show up as intelligible to us is still at the heart of things. What the later thinking involves is a reorientation of the basic project so that, as we shall see, the point of departure is no longer a detailed description of ordinary human experience. (For an analysis of ‘the turn’ that identifies a number of different senses of the term at work in Heidegger's thinking, and which in some ways departs from the brief treatment given here, see Sheehan 2010.)
