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.

Timothy Williamson Open Lecture on Higher-order Metaphysics

by events.isfi＠usi.ch

We are happy to invite you to our open lecture on December 10th from 4:30 pm to 6:00 pm CET The open lecture is born to be a safe and friendly space for every student who wants to have a taste of one of our classes. The MAP is glad to welcome you with the help of Professor Williamson and his “Introduction to Higher-order Metaphysics”. Here is the abstract of the lecture: “Higher-order metaphysics articulates metaphysical questions and theories in formal languages for higher-order logic, in which one can generalize into predicate position, sentence position, operator position, etc., as well as the more usual option of just generalizing into name position. This approach provides a more perspicuous and fruitful framework for metaphysical theorizing than traditional talk of properties, relations, propositions, and the like. The higher-order framework receives independent support from its use in mathematics. Questions about how to interpret higher-order quantification will be discussed. The lecture will keep technicalities to a minimum and will not presuppose any prior acquaintance with higher-order languages.” Open lectures are held on campus for philosophy students and on Zoom for everyone. To attend either in presence or online, please register by filling out the form on this page: https://join.usi.ch/en/master-philosophy-open-lecture If you choose to attend the lecture remotely, we will send you an email to the Zoom meeting a couple of hours before the event. Alternatively, if you prefer to join us on campus, please arrive 20 minutes early for check-in. Don’t miss the opportunity to learn about higher-order metaphysics with Professor Williamson!

Online Talk: A truthmaker semantics for modal logic

by events.isfi＠usi.ch

We are pleased to announce that on Friday, December 6 at 17.00 (CET), Alessandro Giordani (Catholic University Milan, USI) and Vita Saitta (Catholic University Milan) will give the talk A truthmaker semantics for modal logic. 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<mailto:events.isfi@usi.ch>. Abstract: Truthmaker semantics is an innovative framework addressing key philosophical questions about meaning and logic. It is emerging as a significant tool in philosophical logic, challenging possible worlds semantics in areas like semantic and linguistic analysis, non-classical logics, counterfactuals, and modalities. This talk has three main aims. The first is to explore what a semantics for modal notions looks like when adopting a truthmaker semantics, wherein truthmakers for modal sentences are identified with specific kinds of norms. The second is to demonstrate that such a semantics is general enough to allow us to capture modal systems characterized by classes of Kripke frames. The final aim is to prove that this semantics also allows us to capture those modal systems that are characterized by classes of neighborhood frames. The results we obtain are somewhat surprising, as they show that an intuitively appealing idea—namely, that every world is endowed with a set of norms determining which other worlds are possible relative to it---is sufficient for unifying Kripke and neighborhood semantics within the framework of truthmaker semantics.
