the total renunciation of all minimal standards of realism, even at the microscopic level, that the acceptance of the completeness of the theory implied. Since the early days of quantum theory the assumption of locality and Lorentz invariance guided his thoughts and led to his determination that if we demand strict locality then hidden variables are naturally implied apropos EPR. Bell, starting from this EPR logic (which is widely misunderstood or forgotten) showed that local hidden variables imply a conflict with experiment. Ultimately what was at stake for Einstein was the assumption that physical reality be universally local. Although the majority of experts in the field agree that Einstein was wrong, the current understanding is still not complete (see Interpretation of quantum mechanics).
