Motivating Structural Realist Interpretations of Spacetime
نویسنده
چکیده
Motivated by examples from general relativity and Newtonian gravitation, this essay attempts to distinguish between the dynamical structure associated with a theory in physics, and its kinematical structure. This enables a distinction to be made between a structural realist interpretation of a theory based on its dynamical structure, and a structural realist interpretation of spacetime, as described by a theory, based on its kinematical structure. I offer category-theoretic formulations of dynamical and kinematical structure and indicate the extent to which such formulations deflect recent criticism of the radical ontic structural realist's conception of structure as "relations devoid of relata".

Challenging the Spacetime Structuralist
Structural realist interpretations of generally relativistic spacetimes have recently come to enjoy a remarkable degree of popularity among philosophers. I present a challenge to these structuralist interpretations that arises from considering cosmological models in general relativity. As a consequence of their high degree of spacetime symmetry, these models resist a structuralist interpretatio...
متن کاملSpacetime Structuralism
In this essay, I consider the ontological status of spacetime from the points of view of the standard tensor formalism and three alternatives: twistor theory, Einstein algebras, and geometric algebra. I briefly review how classical field theories can be formulated in each of these formalisms, and indicate how this suggests a structural realist interpretation of spacetime.
متن کاملWhat is a wavefunction?
The fact that the wavefunction of a many-body quantum mechanical system is a function on a high-dimensional configuration space, rather than our familiar 3-dimensional space or 4dimensional spacetime, has led to the suggestion, by David Albert and others, 1 that any realist interpretation of quantum mechanics must regard this high-dimensional space as the real arena in which events take place, ...
متن کاملOn the property structure of realist collapse interpretations of quantum mechanics and the so-called “counting anomaly”
The aim of this article is twofold. Recently, Lewis has presented an argument, now known as the “counting anomaly”, that the spontaneous localization approach to quantum mechanics, suggested by Ghirardi, Rimini, and Weber, implies that arithmetic does not apply to ordinary macroscopic objects. I will take this argument as the starting point for a discussion of the property structure of realist ...
متن کاملWhy Constructive Relativity Fails
Constructivists, such as Harvey Brown, urge that the geometries of Newtonian and special relativistic spacetimes result from the properties of matter. Whatever this may mean, it commits constructivists to the claim that these spacetime geometries can be inferred from the properties of matter without recourse to spatiotemporal presumptions or with few of them. I argue that the construction proje...
