Alexander Roberts

I am a Lecturer for the Faculty of Philosophy, University of Cambridge. I recently submitted my DPhil (PhD) thesis, which was written at the University of Oxford under the supervision of Timothy Williamson and James Studd. My main research interests are in metaphysics and philosophical logic. Before starting my DPhil, I received a BPhil (a Master's degree) from Oxford and an undergraduate degree from Leeds. In Spring 2019, I was a Collaborative Visiting Fellow at ConceptLab, University of Oslo. In Spring 2018, I was a visiting student at Rutgers University working under the supervision of Ted Sider. My DPhil was supported by the Clarendon Fund and the Aristotelian Society.

My DPhil thesis, Investigating Necessity, is a collection of essays on the metaphysics and logic of modality. The central theme of the thesis is that various aspects of the theoretical role of metaphysical necessity are incompatible, in the sense that they cannot all be satisfied by a single notion of necessity. Currently, I am drawing on this theme to explore different stable theories of metaphysical necessity in a higher-order setting. The first paper accepted for publication from my thesis is Modal Expansionism, in which I develop a view according to which metaphysical necessity is indefinitely extensibile.

  • 'Relative Necessity and Propositional Quantification', forthcoming in the Journal of Philosophical Logic. [Preprint]
  • 'Imprecise Quantification', forthcoming in the Proceedings of the Aristotelian Society. [Preprint] [Journal]
  • 'Modal Expansionism', forthcoming in the Journal of Philosophical Logic. [Preprint] [Journal]

In Progress:
    I currently have a number of articles on different topics in the metaphysics and logic of modality under review.

This Michaelmas Term, I'll be lecturing on the philosophy of mathematics, Quine, and the metaphysics of modality. Lecture slides and handouts will be made available on Moodle.
