Organized by the inter-university Dutch Categories And Types Seminar, this workshop features talks by John Bourke (Masaryk University, Brno), Wijnand van Woerkom (Utrecht University), Nicola Gambino (University of Leeds), Benno van den Berg (University of Amsterdam) and Paige North (University of Pennsylvania).

Please contact the organizer to join this online talk.

This time we take a recourse to mereology! In his talk, Elias Bronner will introduce the philosophical motivations for the field, Leśniewski's nominalistic position. Further, we will discuss basic mereology and its relation to Boolean Algebras. Elias will conclude with touching upon a recent interpretation of mereology within set theory by J.D. Hamkins which suggests that mereology is too weak of a system to serve as a foundation for mathematics.

We will explore the prospects of a mereological account of proper classes. That is, we will take set theory for granted and consider the hypothesis that proper classes are mereological sums of their parts. Unlike the plural account of classes, for example, the hypothesis construes proper classes as bona fide objects, which are nonetheless significantly different from sets. On the other hand, a mereological account raises questions of its own: if proper classes are bona fide objects, they should be allowed to be members and they should each come with a singleton. But since singletons are arguably mereological atoms, the account will turn out to be incompatible with classical mereology. The question is whether a weaker mereological framework may support a sufficiently rich domain of classes.

On May 17th and 18th, we will have the pleasure of hosting the final workshop of the ERC Cognitive Semantics project. We will have a great lineup of speakers presenting recent advances in semantics and cognition. The day before the workshop, on May 16th, Sonia Ramotowska will defend her thesis "Quantifying quantifier representations: Experimental studies, computational modeling, and individual differences". And the day after the workshop, on May 19th, we will host a half-day satellite meeting on Reasoning & Neural Networks.

All are invited to join the online book launch of Lukas M. Verburgt's John Venn: A Life in Logic  (The University of Chicago Press, 2022) in the form of an online mini-workshop.

This is a hybrid event. Contact the organizer for a link to the online talk.

The Nordic Online Logic Seminar (NOL Seminar) is organised monthly over Zoom, with expository talks on topics of interest for the broader logic community. The seminar is open for professional or aspiring logicians and logic aficionados worldwide.

This is the announcement for the next talk. Those who wish to receive the Zoom ID and password for it, as well as further announcements, can subscribe here: https://listserv.gu.se/sympa/subscribe/nordiclogic .

The Dutch Association for Logic and Philosophy of the Exact Sciences (VvL) is happy to announce the Logic at Large Lecture 2022 aimed at a general audience. We are pleased to announce that Professor Joel David Hamkins (University of Notre Dame) will give a public lecture entitled "Infinite Games & Frivolities of the Gods". The event will take place online using Zoom and will be concluded by a social gathering on the virtual platform Gather.Town.

Registration is free, but necessary to receive links to Zoom and Gather.Town.
