Venue:
Institute of Philosophy, Nicolaus Copernicus University in Toruń,

Event website: https://logika.net.pl/language/en/pcl-2/
The Congress aims to present key research relevant to the development of contemporary logic, with particular emphasis on the contribution of Polish logicians. The Polish Association of Logic and Philosophy of Science (PTLiFN), the second-oldest logic society in the world (after the Association for Symbolic Logic in the USA), is the main initiator of the first edition of the Polish Congress of Logic.
This event refers to the ethos of Polish logicians, particularly within the Lvov–Warsaw School and the Polish School of Mathematics. At the same time, it is intended to unite researchers currently working in logic in Poland and abroad, and to facilitate the exchange of scientific results and professional experience.
