Einstein’s statements expressing his admiration for Spinoza are well known and have led some commentators to attempt to identify their theoretical parallels and to seek to answer the question of whether Spinoza’s philosophy had, to any extent, an influence on Einstein’s thinking and theory. The answers typically settle on determinism, realism, and intellectualism as rationalist shared moments of the two rationalist thinkers. The study presented here accepts these conclusions as initial assumptions and focuses instead on a closer examination of the “rationalist” method that both thinkers considered to be highly scientific and which they were not only able to formally articulate, but also to precisely apply in their own thought processes. The study thus aims to demonstrate that it is precisely this method, primarily consisting of intuitive deduction and an adequate definition of the objects of investigation, that unites both thinkers, and that it is also extremely likely that Einstein’s rejection of the interpretations of quantum theory at that time was also due to his devotion to this “intuitive physics.”
