On Realism and Quantum Mechanics
نویسنده
چکیده
After the definition of a ‘tempered realism’ which rejects a priori ontological propositions, it is shown that basic statements belonging to ‘orthodox’ interpretations of Quantum Mechanics, are realist in a stronger sense because they insert ontological statements like those about the existence of the ‘superposition’ state or of the ‘entangled’ state in the postulates of the theory. A discussion of EPR issues suggests that descriptions containing only statements about state vectors and experiments outputs are the most suitable for Quantum Mechanics: if we follow this prescription, we find that the concept of non locality with its ‘instantaneous action at a distance’ evaporates. Finally, it is argued that usual treatments of philosophical realist positions end up in the construction of theories whose major role is that of being disproved by experiment. This confutation proves simply that the theories are wrong; no conclusion about realism (or any other philosophical position) can be drawn, since experiments deal always with theories and these are never logical consequences of philosophical positions.

Macroscopic Local Realism Incompatible with Quantum Mechanics: Failure of Local Realism where Measurements give Macroscopic Uncertainties
We show that quantum mechanics predicts a contradiction with local hidden variable theories for photon number measurements which have limited resolving power, to the point of imposing an uncertainty in the photon number result which is macroscopic in absolute terms. We show how this can be interpreted as a failure of a new premise, macroscopic local realism. Bell [1] in 1966 showed that the pre...
متن کاملOntic structural realism and the interpretation of quantum mechanics
This paper argues that ontic structural realism (OSR) faces a dilemma: either it remains on the general level of realism with respect to the structure of a given theory, but then it is, like epistemic structural realism, only a partial realism; or it is a complete realism, but then it has to answer the question how the structure of a given theory is implemented, instantiated or realized and thu...
متن کاملThe uninvited guest: ‘local realism’ and the Bell theorem
According to a wrong interpretation of the Bell theorem, it has been repeatedly claimed in recent times that we are forced by experiments to drop any possible form of realism in the foundations of quantum mechanics. In this paper I defend the simple thesis according to which the above claim cannot be consistently supported: the Bell theorem does not concern realism, and realism per se cannot be...
متن کاملReconciling local realism with quantum mechanics: the generalized BCHSH inequalities
Most physicists uphold that the tests of the Bell–Clauser, Horne, Shimony and Holt (BCHSH) inequalities confirm quantum mechanics (QM) and refute local realism. Some scholars, however, criticize this conviction, yet maintaining that QM conflicts with local realism. At variance with both viewpoints one of the authors has recently worked out an extended semantic realism (ESR) model which shows th...
متن کاملRestoring physical realism
Problem Many attempts have been made, starting from Quantum mechanics (QM), to prove the non-viability of hidden-variable (HV) solutions, and to justify the unnaturalness of QM explanations over physical realism. In particular, Colbeck & Renner (C&R) (2011) claimed to prove that no extension of quantum theory can exist with better predictive power than quantum mechanics itself. This implies tha...
