Philosophy of Mathematics Seminar


The Philosophy of Mathematics seminar covers topics beyond the philosophy of mathematics and logic, including applications of formal methods in philosophy more generally. Speakers come from different disciplines, such as philosophy, computer science, and mathematics. The content of the talks vary from highly technical to purely informal.

All are welcome to attend the seminar. Graduate and undergraduate students from all subject areas are especially welcome. It is perfectly acceptable to attend only selected talks. 

The following meetings of the Philosophy of Mathematics Seminar will take place in Hilary Term 2024 online via Zoom on Mondays 4.30-6.30 pm in weeks 2, 4, 6, and 8, and also in person in weeks 2 and 4 in the Ryle Room of the Radcliffe Humanities Building. 

If you’re not on the circulation list for announcements and would like to attend, write to Daniel Isaacson.

Philosophy of Mathematics Seminar Convenors: James Studd, Christopher Scambler and Daniel Isaacson | Philosophy of Mathematics website
