General Relativity and Philosophy

Is philosophy useful for physics? Many physicists and philosophers believe that it is; but there are those who challenge the usefulness of philosophy for science. Three major objections can be identified in their reasoning: 1. Philosophy’s death diagnosis, which states that philosophy is dead and has nothing new to teach us. 2. Historic-agnostic argument/challenge, which states that there is no historical evidence for the claim that philosophy is useful for science, or if it is, it is unknown to us. 3. The division of property argument, which states that philosophy and science are two distinct fields. The purpose of this article is to respond to these three objections by examining the case study of the relationship between general relativity and philosophy. By looking at the history of the formation and development of general relativity, we will argue that: 1. Philosophy has led to a refinement and deep understanding of the important concepts of covariance and invariance. 2. There is clear historical evidence for the positive influence of philosophy on the development of the core concepts of general relativity, as one of the most important physical theories, as well as the undeniable evidence for the key role of some philosophers in the development of the theory. 3. Physics and philosophy, in seeking answers to fundamental questions, are two highly intertwined fields.
