This is a reprinting of Ruark’s response to the EPR paper. Ruark puts the EPR debate down to disagreement over the criterion of reality. Ruark states that the majority of physicists will, pace EPR, consider this criterion satisfied even when the elements of a theory correspond only to indirectly measured features of reality.
This is a reprinting of Margenau’s response to EPR (and to some extent, his evaluation of previous responses to EPR by Bohr, Kemble and Ruark). Margenau’s contribution to the EPR debate is certainly one of the most original, no doubt at least in part due to the meaty correspondence he had with Einstein while producing it. Margenau’s main strategy in this paper is to argue against the standard collapse postulate of quantum mechanics, suggesting that the EPR argument only applies to quantum mechanics with this postulate added. He also argues against the statistical interpretation of the collapse postulate suggested by Kemble and others.
