Both Einstein and Spinoza shared a similar perspective on the existence of God; neither believed in a God that had a personal interaction with humanity. Instead, they saw evidence of a divine design in the universe's intricate laws. This belief was not just a matter of faith for Einstein; he considered it fundamental to his understanding of physics, paralleling how he valued the principle of relativity.
Einstein approached scientific theories with a unique mindset. He questioned whether, if he were in a divine position, he would have structured the world in a specific manner, using this thought process to evaluate the validity of theories. This perspective influenced the way he conducted his work and shaped his broader philosophical views on the universe.
