In letters to Besso in 1952, Einstein defended his stubbornness. He insisted that a complete description of nature would describe reality, or a “deterministic real state,” rather than merely describe observations. “The orthodox quantum theoreticians generally refuse to admit the notion of a real state (based on positivist considerations). One thus ends up with a situation that resembles that of the good Bishop Berkeley.” Einstein to Michele Besso, Sept. 10, 1952, AEA 7-412. A month later he noted that quantum theory declared that “laws don’t apply to things, but only to what observation informs us about things
