There is an obvious example with Heidegger. https://plato.stanford.edu/entries/heidegger/#Lat > After Being and Time there is a shift in Heidegger's thinking that he > himself christened ‘the turn’ (die Kehre). ... > > 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.)
