All knowledge of reality starts from experience and ends in it. But he immediately proceeded to emphasize the role that pure reason and logical deductions play. He conceded, without apology, that his success using tensor calculus to come up with the equations of general relativity had converted him to a faith in a mathematical approach, one that emphasized the simplicity and elegance of equations more than the role of experience. The fact that this method paid off in general relativity, he said, justifies us in believing that nature is the realization of the simplest conceivable mathematical ideas.45
This excerpt discusses the relationship between experience and reason in understanding reality, highlighting Einstein's transformative journey. While he acknowledges that experience serves as the foundation for knowledge, he stresses that pure reason and logical deductions are equally important. He reflects on how his work with tensor calculus in developing the equations of general relativity reinforced his belief in a mathematical approach that values simplicity and elegance over experiential evidence.
Einstein's success with general relativity led him to a conviction that the underlying nature of the universe can be explained through straightforward mathematical concepts. This perspective suggests a harmony between mathematics and the physical world, illustrating that complex realities may ultimately stem from simple ideas. His insights encourage a deeper appreciation for the interplay between empirical experience and the power of logic and mathematics in scientific exploration.
