Tim Button is Head of the Philosophy Department, and a Professor of Philosophy & Logic, at UCL.

I work at the area where philosophy meets logic and mathematics. Here are some short words about some things I like. Right now, I am thinking about theoretical equivalence, types, and sets.

I recently published a serialized trilogy on Level Theory. Before that, Sean Walsh and I published Philosophy and Model Theory (OUP, 2018). My first book was The Limits of Realism (OUP, 2013). I have made some open education resources. I am an associate editor of MIND.

You can email me at . This is my main site, and gives you access to pre-prints (or better) of all my papers. I have less well maintained profiles at arXiv, google scholar, ORCID, PhilPapers, and UCL Profiles. (I have stopped maintaining my academia & SocArXiv profiles.)
