Symmetry, Structure, and Spacetime Philosophy and Foundations of Physics Series

In this book Rickles considers several interpretative difficulties raised by gauge-type symmetries (those that correspond to no change in physical state). The ubiquity of such symmetries in modern physics renders them an urgent topic in philosophy of physics. Rickles focuses on spacetime physics, and in particular classical and quantum general relativity. Here the problems posed are at their most pathological, involving the apparent disappearance of spacetime! Rickles argues that both traditional ontological positions should be replaced by a structuralist account according to which relational structure is what the physics is about.

Dean Rickles's main research interests lie in the general area of philosophy of physics, especially quantum gravity. He recently coedited a book on The Structural Foundations of Quantum Gravity (Oxford University Press, 2006) and has a forthcoming edited philosophy of physics textbook: The Ashgate Companion to the New Philosophy of Physics (Ashgate, 2008).
