We are pleased to announce that on Thursday, December 12 at 5.30pm (CET) , Timothy Williamson (Oxford) will give the talk Temporal Logic as Metaphysics as part of the Lugano Philosophy Colloquia Fall 2024 organised by the Institute of Philosophy (ISFI) at USI. This hybrid talk will take place in Room Multiuso, FTL Building (USI West Campus) and online via Zoom. If you are interested in joining online, please write to events.isfi(a)usi.ch. Here is the abstract of the talk: The talk will explain a logic-based approach to the metaphysics of time. As the title hints, it will be analogous to the logic-based approach to the metaphysics of possibility and necessity developed in Modal Logic as Metaphysics, though knowledge of that book will not be presupposed. I will discuss the purely logical sense of ‘exist’ and its interaction with temporal operators, the contrast between permanentism (the thesis that always everything is always something) and its denial, temporaryism (the thesis that sometimes something is sometimes nothing), and the logical nature of genuine change.
