Joshua Rosaler (University of Pittsburg / University of Minnesota): "Interpretation Neutrality in the Classical Domain of Quantum Theory". Listen to the talk here.

Abstract: In this paper, I seek to alleviate a tension that arises in the effort to account for macroscopic Newtonian behavior within quantum theory: namely, the tension between, on the one hand, a desire to have a clearly defined quantum theory to serve as the basis of the analysis (that is, a theory that avoids the vagueness and ad hoc-ness of the conventional interpretation of quantum theory) and, on the other hand, a certain hesitancy prevalent among many philosophers of physics to commit to any of the existing realist proposals for correcting the vagueness of conventional quantum theory. Prima facie, it would seem that the task of retrieving Newtonian behavior from quantum mechanics in the macroscopic realm depends strongly on the particular interpretation of quantum mechanics that one adopts specifically, because the question of how one extracts the determinacy of Newtonian descriptions from a theory that allows indeterminate superpositions depends entirely on the attitude that one takes toward the measurement problem and its resolution. In this paper, I argue that, within the context of realist approaches to the measurement problem, the manner of accounting for Newtonian behavior is to a very large extent independent of the particular realist interpretation that one adopts as the basis for the analysis.
