I wanted to let you know about a paper that was recently put on the arXiv which I think you and many readers of this site will find very interesting, in case it hasn’t been noticed yet:
Penelope Maddy & Jouko Väänänen “Philosophical Uses of Categoricity Arguments” https://arxiv.org/abs/2204.13754
This does indeed on a quick skim look a seriously interesting and thought-provoking paper (though not an easy read: there is a lot of detailed argument here). Thanks for the pointer!
