I just came across a short post by Leiter with the unbelievable title 'European formal philosophers, don't relax yet...', which made me truly uncomfortable. I've said before in comments here that, in my opinion, to insist on the differences between 'Americans' and 'Europeans' in the Synthese affair is only likely to make matters even worse. It is my conviction that a lot of the drama has been caused precisely by mutual misunderstanding on both sides, but this is all the more reason to avoid this kind of polarization and stereotypical generalization at this point. Even as a joke, it's not funny, unless Leiter's goal was to alienate even further those 'European formal philosophers' who are truly dissatisfied with the editorial decisions made by the EiC as well as with their later statements, but who may think that a boycott approach is not the most likely way to reach a resolution of the situation. (That's roughly my own position; do I count as an 'European formal philosopher'?)
For the record, I do think that the attribution of parochialism to the critics of the EiC coming from my esteemed colleagues Martin Stokhof and Frank Veltman (and there's not a hint of irony here, they are both fantastic colleagues and philosophers) was itself parochial. But by putting up a post like this, I'm not sure what exactly Leiter is trying to accomplish, beyond provoking even more unhelpful animosity.
UPDATE - Leiter has added an update in his original post, which addresses some of the concerns that have been voiced here.
