Abstract

This chapter considers the prospects, in the present state of research in quantum mechanics, for an ontological foundation for the theory that is compatible with the minimal constraints of scientific realism, that is, compatible with the attribution of physical states to particles. No single interpretation is defended, but it is argued that no-collapse theories such as the various “many-worlds” interpretations cannot coherently satisfy such constraints, while objective collapse theories such as the Ghirardi-Rimini-Weber (GRW) theory offer the possibility, at least, of satisfying both these conceptual constraints and the empirical constraints of quantum phenomena.

Notes

  1. 1.

    See (Putnam 2004), especially the last two chapters, for a discussion.

  2. 2.

    Something I learned from reading Sheldon Goldstein .

  3. 3.

    For a list of related difficulties with the decoherent histories approach, see Ghirardi (2007).

  4. 4.

    See http://www.mathematik.uni-muenchen.de/~bohmmech/BohmHome/weingold.htm.

  5. 5.

    Also see the discussion in (Maudlin 2007, p. 3166) or Maudlin 2002.
