The paper shows that the past, “history” in a non-technical sense, can be changed in quantum mechanics. The first part of the paper reviews Deutsch's analysis in his paper of 1991. It is demonstrated that Deutsch assumes the existence of a multiplicity of essentially classical worlds. Such a multiplicity of worlds would allow the past to be changed in classical mechanics. It is argued that the existence of multiple “classical” worlds is not required by quantum mechanics. It is then shown (...) that it is possible to change the past in conventional quantum mechanics even without the assumption of a multiplicity of worlds. (shrink)

The article aims at a determination of Heidegger's contribution to a theory of subjectivity and self-consciousness. It does so through a discussion of Øverenget's book on this topic and in particular of his thesis that according to Heidegger the self is given “with” our consciousness of objects. Three ways are considered in which this thesis might apply on the one hand to Heidegger's argument and on the other to the phenomenon in question: with Kant as an expression of a functional (...) conception of our self-awareness, as a determination of its epistemic structure, and as a claim of the irreducible concreteness of subjectivity. It is, among other things, argued that the first way at best does not exhaust the thesis, that the second way corresponds to Heidegger's intention, but that his argumentation does not reach such a determination, and that the third way expresses both his ultimate intention and the field of his real contribution in the theory of subjectivity. Besides, it is argued that Heidegger at these points is much closer to German idealism than he and Øverenget realize. (shrink)
