J.S. Bell's work has convinced many that correlations in violation of CHSH inequalities show that the world itself is non-local, and that there is an apparently essential conflict between any sharp formulation of quantum theory and relativity. Against this consensus, this paper argues that there is no conflict between quantum theory and relativity. Quantum theory itself helps us explain such (otherwise) puzzling correlations in a way that contradicts neither Bell's intuitive locality principle nor his local causality condition. The argument depends on understanding quantum theory along pragmatist lines, and on a more general view of how that theory helps us explain. Quantum theory is compatible with Bell's intuitive locality principle and with his local causality condition not because it conforms to them, but because they are simply inapplicable to quantum theory, as so understood.

Despite the many successes of quantum mechanics, a minority within the physics community feels unease and has loudly expressed their discomfort. There are unresolved foundational questions, the measurement problem, wave particle duality, non-local effects, etc. This feeling arises when one realizes that quantum mechanics implies a number of counter-intuitive notions. This has led such a great physicist as Niels Bohr to comment, “Anyone who is not shocked by the quantum mechanics theory does not understand it!” In the same vein, Roger Penrose exclaimed: “Something new will have to come in and change the structure of quantum mechanics.”
