After the enjoyable Second Cambridge Graduate Conference on the Philosophy of Logic and Mathematics back in January, I wrote up some remarks I gave responding to a talk by Julien Murzi and Ole Hjortland, based on their ‘Inferentialism and the Categoricity Problem: Reply to Raatikainen‘ (which is coming out in Analysis). Luca Incurvati independently shared my worries about what they say about Smiley and rejection, and had more points to make about their remarks on intuitionism. Putting our thoughts together, Luca and I have come up with a joint paper “Rejection and valuations“, now also forthcoming in Analysis: it has, we hope, some stand-alone interest, if you want a steer on what is going on in Smiley’s original paper on Rejection. Enjoy!

Ole Thomassen HjortlandThanks to both of you. Looking forward to reading it.
