Through the paralyzing paradoxes of Professor Polaro I have learned that The History of Categorical Logic by Jean-Pierre Marquis and Gonzalo E. Reyes is available online for free. So far I just took a quick look, but it seems like a good read. Here.
My visit to Bristol is over, I'm back home (i.e. in Poland) for a few weeks. I used some of the spare time to finish drafting the first paper that I worked on with Oystein Linnebo last semester (stay tuned for another one). The paper is titled Nominalist Neologicism and contains the core of the modal-iterative approach to abstraction principles that I've been advocating over the last year or so. It's based on a talk I gave in Frankfurt (Trends in the Philosophy of Mathematics), so the style is a bit relaxed. If you plan to take a look at it, please let me know in a comment below this post, so that I know I should expect feedback from you. The deadline is Jan 15, so if you have any comments, please share them with me by Jan 10. Here.
I see Louis deRosset has posted a few nice pieces related to modalities on his website. These include "Possible worlds I: Modal Realism", "Possible Worlds II: Nonreductive Theories of Possible Worlds" and his dissertation "Modal Primitivism: A study in the metaphysics of Necessity and Possibility".
