This paper aims to motivate Bell’s notion of local causality by means of Bayesian networks. In a locally causal theory any superluminal correlation should be screened off by atomic events localized in any so-called shielder-off region in the past of one of the correlating events. In a Bayesian network any correlation between non-descendant random variables are screened off by any so-called d-separating set of variables. We will argue that the shielder-off regions in the definition of local…

Bell’s Notion of Local Causality

The three key concepts featuring in Bell’s final formulation of local causality, namely “local beables,” “shielder-off region”, and “complete specification” are translated into the LPT framework and a generalized definition ofLocal causality is provided.

Relating Bell’s Local Causality to the Causal Markov Condition

The aim of the paper is to relate Bell’s notion of local causality to the Causal Markov Condition. To this end, first a framework, called local physical theory, will be introduced integrating…

Local causality and complete specification: a reply to Seevinck and Uffink

A physical theory is called locally causal if any correlation between spacelike separated events is screened-off by local beables completely specifying an appropriately chosen region in the past of…

Bell ’ s concept of local causality

John Stewart Bell’s famous theorem is widely regarded as one of the most important developments in the foundations of physics. Yet even as we approach the 50th anniversary of Bell’s discovery, its…

Causal Markov, Robustness and the Quantum Correlations

It is still a matter of controversy whether the Principle of the Common Cause (PCC) can be used as a basis for sound causal inference. It is thus to be expected that its application to quantum…

On the concept of Bell’s local causality in local classical and quantum theory

The aim of this paper is to implement Bell’s notion of local causality into a framework, called local physical theory. This framework, based on the axioms of algebraic field theory, is broad enough…

Non-separability Does Not Relieve the Problem of Bell’s Theorem

This paper addresses arguments that “separability” is an assumption of Bell’s theorem, and that abandoning this assumption in our interpretation of quantum mechanics (a position sometimes referred to…

I discuss various formulations of stochastic Einstein locality (SEL), which is a version of the idea of relativistic causality, that is, the idea that influences propagate at most as fast as light.…

Relativistic Causality in Algebraic Quantum Field Theory

This paper surveys the issue of relativistic causality within the framework of algebraic quantum field theory (AQFT). In doing so, we distinguish various notions of causality formulated in the…

Interventions and Causality in Quantum Mechanics

I argue that the Causal Markov Condition (CMC) is in principle applicable to the Einstein–Podolsky–Rosen (EPR) correlations. This is in line with my defence in the past of the applicability of the…
