This workshop will commemorate the philosophical work and legacy of Gottlob Frege on the occasion of the centenary, in 2025, of his death. It aims to bring together philosophers working on Frege’s and Fregean approaches to logic and the philosophy of mathematics, both from a historical and a contemporary perspective.
