Salmon’s Theory of Causal Explanation and Quantum Mechanics

Abstract

Salmon has said that his theory of causal explanation is not fully adequate for the quantum domain because of certain causal anomalies such as the wave/particle dualism and, in particular, the statistical correlations which arise from EPR-type experiments. This paper analyzes Salmon’s causal notions, on which his probabilistic theory of explanation is based, in order to delimit its scope within that domain by showing that it covers only transition processes but not processes of transmutation. Beside, I propose, very roughly, an alternative notion of indeterministic causality, intended to be adequate for certain quantum processes as stochastic processes. Finally, I also argue that, while the explanation of the quantum correlations is an open problem, is would be a mistake to think that a theory of causal explanation, like Salmon’s, conceived and worked out primarily for individual physical processes, could and should account for such correlations.
