This chapter provides an up-to-date, comprehensive discussion of substantivalist and
relationalist approaches to spacetime. It analyzes why Isaac Newton postulated absolute …

This paper scrutinises the tenability of a strict conceptual distinction between space (time)
and matter via the lens of the debate between modified gravity and dark matter. In particular …

Our best theory of space, time, and gravity is the general theory of relativity (GR). It accounts
for gravitational phenomena in terms of the curvature of spacetime. In more mathematical …

The presence of symmetries in physical theories implies a pernicious form of
underdetermination. In order to avoid this theoretical vice, philosophers often espouse a …

Radical ontic structural realism (ROSR) claims that structure exists independently of objects
that may instantiate it. Critics of ROSR contend that this claim is conceptually incoherent …

The aim of this thesis is to extend the success of a novel strategy for the interpretation of
symmetry-related models—sophistication—to contemporary physical theories' internal …

We should see the debate over the existence of spacetime as a debate about the
fundamentality of spatiotemporal structure to the physical world. This is a non-traditional …

The hole argument purports to show that all spacetime theories of a certain form are
indeterministic, including the General Theory of Relativity. The argument has given rise to an …

This paper pushes back against the Democritean-Newtonian tradition of assuming a strict
conceptual dichotomy between spacetime and matter. Our approach proceeds via the more …

I explore some of the ways that assumptions about the nature of substance shape
metaphysical debates about the structure of Reality. Assumptions about the priority of …
