Part 2: The Third Logical Type.

Abstract
In Part 1 the properties of QBism are shown to be natural consequences of taking quantum mechanics at face value, as does Everett in his Relative State Formulation (1957). In Part 2 supporting evidence is presented. Parmenides' (Palmer, 2012) notion that the physical world is static and unchanging is vividly confirmed in the new physics. This means the time evolution of the physical world perceived by observers only occurs at the level of appearances as noted by Davies (2002). In order to generate this appearance of time evolution, a moving frame of reference is required: this is the only possible explanation of the enactment of the dynamics of physics in a static universe.
Such a frame of reference can only be a fundamental property of the unitary system as a whole, of different logical type to the quantum state. Thus an ontological category in addition to physical existence is required to complete the science. At this level of logical type, all multiply instantiated copies of an inside view constitute a single entity. Thus the superposition proposed in Part 1 is inevitably effected; and the nature of physical reality on the inside view is as described in QBism.
