Imaginable Impossibilities and Thought Experiments

Some images from our conference on medieval logic and modalities

We had three beautiful and exciting days in Parma, during our conference “Logic and Modalities in the Late Middle Ages” which took place on October 17-19.

The conference was one of the milestones of our Calculatores Project, and it was a real pleasure to host at UNIPR so many young and senior scholars from all over the world.

The next appointment is to June 2024, when Parma will host the next European Symposium on Medieval Logic and Semantics, organized by Irene Binini and Fabrizio Amerini.

Here are some images from these days. Below, you may find the event’s programme.
