Bub and Dieks both take this to mean that von Neumann uses assumption B' to define linear combinations of physical quantities that are not simultaneously measurable. This is the entire basis for their criticisms of Bell and Hermann. If B' is just a definition, it cannot also be an invalid assumption, as Hermann and Bell maintain. But [...] the full set of von Neumann's four assumptions contains another way to define linear combinations of physical quantities that are not simultaneously measurable. With that alternative definition, Assumption B' can indeed impose a nontrivial constraint on the values an Exp function can have for such linear combinations. There is no reason to insist that Assumption B' must be taken as a definition.
Although an atheist for most of his life, while at Queen's University [John Bell] had many discussions with a Catholic friend, Denis McConalogue, about the devil, and even attended some meetings of the Student Christian Movement for the sake of argument.
Non-contextual hidden variables are those that fix values or probabilities or expectation values for all quantum mechanical observables, independent of any experimental context. The impossibility proofs of von Neumann (1932), Gleason (1957), and Kochen and Specker (1967) refer to this kind of hidden variables.
