Einstein was interpreted as a relativist by many (including some whose disdain fueled their anti-Semitism.) This was not the case. Beneath all of Einstein’s theories, including relativity, was a quest for certainties and absolutes. In fact, he considered calling his masterwork “Invariance Theory” rather than “Relativity Theory,” because it was based on underlying invariances and certainties. His objection to quantum mechanics was that it assumed that the realities of the universe depended on our observation of it, which conflicted with his own faith that there was a reality that existed independent of our ability to observe it.
