MCMP – Philosophy of ScienceOn Bell's local causality in local classical and quantum theoryGábor Hofer-Szabó (Budapest) gives a talk at the MCMP Colloquium (9 April, 2014) titled "On Bell's local causality in local classical and quantum theory". Abstract: This paper aims to give a clear-cut definition of Bell's notion of local causality. Having provided a framework, called local physical theory, which integrates probabilistic and spatiotemporal concepts, we formulate the notion of local causality and relate it to other locality and causality concepts. Then we compare Bell's local causality with Reichenbach's Common Cause Principle and relate both to the Bell inequalities. We find a nice parallelism: both local causality and the Common Cause Principle are mo...

Abstract: In the talk we characterize the different interpretations of QM in an operationalist-frequentist framework and show what entities the different interpretations posit. We define completeness and correctness of an interpretation in terms of how this posited ontology relates to the "real world ontology" posited by principles independent of the interpretations. We argue that the Reality Criterion is just such a principle. We also argue that the EPR argument, making use of the Reality Criterion, is devised to show that ce...
