    "abstract": "H. P. Stapp has proposed a number of demonstrations of a Bell-type theorem\nwhich dispensed with an assumption of hidden variables, but relied only upon\nlocality together with an assumption that experimenters can choose freely which\nof several incompatible observables to measure. In recent papers his strategy\nhas centered upon counterfactual conditionals. Stapp\u0027s paper in American\nJournal of Physics, 2004, replies to objections raised against earlier\nexpositions of this strategy and proposes a simplified demonstration. The new\ndemonstration is criticized, several subtleties in the logic of counterfactuals\nare pointed out, and the proofs of J. S. Bell and his followers are advocated.",
