Abstract

David Mermin suggests that my recent proof pertaining to quan tum nonlocality is undermined by an essential ambiguity pertaining to the meaning of counterfactual statements in quantum physics The ambiguity he cites arise from his imposition of a certain criterion for the meaningfulness of such counterfactual statements That criterion con ates the meaning of a counterfactual statement with the details of a proof of its validity in such a way as to make the meaning of such a statement dependent upon the context in which it occurs That dependence violates the normal demand in logic that the meaning of a statement be de ned by the words in the statement itself not by the context in which the statement occurs My proof conforms to that normal requirement I describe the context independent meaning within my proof of the counterfactual statements in question..
