Nonlocality: a defence of widespread beliefs

It has been argued, on the basis of an equivalence between the existence of a joint probability distribution for incompatible observables and the satisfaction of the Bell inequalities, that these inequalities are irrelevant to the issue of (non)-locality; and that this issue arises only if we adhere to a notion of objectivity in the description of physical systems that is not justified in quantum mechanics. These arguments are discussed in the orthodox and in the unsharp approach to quantum mechanics, and found defective: the Bell inequalities turn out to be relevant both in the orthodox and in the unsharp approach.
