“The noscript of this book may sound to some readers like Good as Evil, or perhaps Cabbages as Kings. If logic and metaphysics appear disjoint, the reason is not just the lingering spell of a logical positivist conception of metaphysics as cognitively meaningless and logic as cognitively meaningful but analytic.”

Consider the contrast between a newtonian conception of absolute space and a Galilean conception of relative space. The relativist claims that there is no fact of the matter about absolute motion, no difference between an inertial frame moving at constant velocity through space and the frame at rest. The newtonian acknowledges that according to the physical theory they both accept, there is no difference in the way bodies behave in an inertial frame at rest and the way they behave in one moving at constant velocity. The issue between the absolut- ist and the relativist is whether there is a metaphysical difference.

The upshot is that in a coherent equivalence system, worlds indistinguishable at a given world must in particular be indistinguishable in terms of indistinguishability.
