Rule Perspective and the Everett Interpretation to understand quantum theory without supplementing its standard formalism in any way.

Dissolving the paradoxes
========================

The present section gives an outline of how the epistemic conception of quantum states dissolves the measurement problem and the problem of quantum “non-locality”, that is, the claimed tension between quantum theory and relativity theory. I consider the measurement problem first.

The measurement problem
-----------------------

There are various different formulations of the measurement problem in the literature, sometimes even conceived of as different measurement problems.[^5] Here I focus on an exposition due to [@maudlin95] (who alone gives three different formulations), to illustrate how the epistemic conception of quantum states dissolves it. In Maudlin’s formulation, the problem arises from the incompatibility of the following three assumptions:

> 1.A The wave-function of a system is complete, i.e. the wave-function specifies (directly or indirectly) all of the physical properties of a system.\
> 1.B The wave-function always evolves in accord with a linear dynamical equation (e.g. the Schrödinger equation).\
> 1.C Measurements of, e.g., the spin of an electron always (or at least usually) have determinate outcomes, i.e., at the end of the measurement the measuring device is either in a
