article description
In his 2013 Foundations of Physics paper Mathias Egg claims to show that my critical arguments toward the foundational significance of Leggett’s non-local theories are misguided. The main motivation is that my argument would connect too strongly the Leggett original motivation for introducing this new class of theories with the foundational significance of these theories per se. Egg basically aims to show that, although it can be conceded that the Leggett original motivation relies on a mistaken view of the original Bell theorem, the investigation on the Leggett theories does have a foundational meaning that can be disassociated from the view that Leggett himself has of of them. As a reply to Egg, I would like to argue here that, even if we assume to disentangle the Leggett view from the fate of the Leggett theories, there is still room to dispute the foundational significance of the Leggett ‘non-local realistic’ research program.
