I should pointoutthat I did not make it clear in the original presentation that Iamtalking about states that are defined at two or more distinct spacetime points. If you have everything at a single point, the distinction between locality and separability becomes blurred.So, inmore detail. We have a state defined at two distinct spacetimepoints,x and y: C(x,y). If we assume Humeanism, each spacetime point is complete and independent of all other spacetime points. This islocality,his is a far stronger constraint than locality, it's onlysatisfied inclassical models with local interactions.It is the relevant concept of locality for consideration of theBellcorrelations. HV models are, in fact, essentially classicalmodelswith local interactions. Other formulations of the localitypostulatealso imply Humeanism -- the complete state of the world isdeterminedby the intrinsic physical state of each spacetime point and the spatio-temporal relations between these points.Local realism, QM is local but does not satisfy realism.It has nothing to do with realism. Local physics is completely defined by what happens at the individual spacetime points. But that does not imply that variables have definite values before they are measured. We allow for stochastic dependence on the physics at local spacetime points and also allow for MWI -- the operation of the deterministic Schrodinger equation giving every possible outcome on every interaction. If you are not careful, you are going to make MWI realistic. The Humean assumption underlies any local theory, including MWI if that can be shown to be local. It is not intrinsically realist. Locality implies separability. If you disagree, show me the mathematics of a local state (referring to distinct spacetime points) that is not separable -- without begging the question, that is!

`Locality refers to the dynamics of a theory, not to properties of some`

`particular state. In classical physics, you don't have non-separable`

`states, but you can get to non-local correlations using only local`

`dynamics. In QM you can get to non-separable states using only local`

`dynamics. The mere fact that you can have non-classical entangled states`

`does not imply that the dynamics of the theory is non-local`
