ABSTRACT
Reality is a word that carries many meanings and subtlely nuanced concepts. In order to have some reliable understanding of what Einstein and Tagore could have meant when they talked about reality, it is necessary to glean their conceptions from a broad survey of their writings and utterances over many years. Tagore's view on reality was strongly epistemological in character. He was by no means an orthodox idealist, as he is often made out to be. The predominant view is that quantum reality is fundamentally different from classical reality. The uncontrollable effect of a measurement on a quantum system makes all observed phenomena intrinsically probabilistic in nature, and the distinction between the observer and the observed is blurred. The putative nonlocality of quantum mechanics is usually inferred from violations of Bell inequalities by entangled quantum states. However, there are many interpretations of quantum mechanics that do away with this controversial postulate, such as Everett's interpretation and its offspring.
