Absolute representations and modern physicsAbsolute representations and modern physicsC. Jacobs and J. Read

Famously, Adrian Moore has argued that an absolute representation of reality is possible: that it is possible to represent reality from no particular point of view. Moreover, Moore believes that such absolute representations are a desideratum of physics. Recently, however, debates in the philosophy of physics have arisen regarding the apparent impossibility of an absolute representation of certain aspects of nature in light of our current best theories of physics. Throughout this article, we take gravitational energy as a particular case study of an aspect of nature that seemingly does not admit of an absolute representation. There is, therefore, a prima facie tension between Moore’s a priori case on the one hand, and the state-of-play in modern physics on the other. This article overcomes this tension by demonstrating how, when formulated in the correct way, modern physics admits of an absolute representation of gravitational energy after all. In so doing, the article offers a detailed case study of Moore’s argument for absolute representation, clarifying its structure and bringing it into contact with the distinction drawn by philosophers of physics between coordinate-freedom and coordinate-independence, as well as the philosophy of spacetime physics.
