The paper entitled “Situated Counting“, written by Peter Gärdenfors & Paula Quinon, has been published in Review of Philosophy and Psychology (open access). We encourage everyone interested to read it: https://link.springer.com/article/10.1007/s13164-020-00508-3.

The steps require conceptual knowledge of three components: numerosity as a property of collections; numerals; and one-to-one mappings between numerals and collections. We argue that establishing one-to-one mappings is the central feature of counting. In the literature, the…continue reading →

On Friday, 2 October, Carlo Rovelli (Aix-Marseille University) will give a talk entitled "Why can we decide what we shall do tomorrow, but we cannot decide what we did yesterday? Time reversibility and the physics of an agent" (abstract below). The meeting will take place online on Zoom (16:00-18:00 CET). If you have not registered yet, you can do so by sending a message to antonio.vassallo@pw.edu.pl. The program for the winter semester can be found here.
