  Notice that while, in the turning, “everything is reversed”, nevertheless it is “not a change of standpoint from Being and Time”, so what we should expect from the later philosophy is a pattern of significant discontinuities with Being and Time, interpretable from within a basic project and a set of concerns familiar from that earlier text. The quotation from the Letter on Humanism provides some clues about what to look for. Clearly we need to understand what is meant by the abandonment of subjectivity, what kind of barrier is erected by the language of metaphysics, and what is involved in the oblivion of Being. The second and third of these issues will be clarified later. The first bears immediate comment.
