Three and a half years ago I had the pleasure of doing a guest post here on PEA Soup. I'm still working on the same stuff, so I thought I'd start my non-guest posting with an update. There's quite a few things going on in the paper, so I'll just try to hit the highlights here in the hopes that it generates discussion. (I'll also be talking about this stuff at RoME in August, for those of you who will be there.)
I think that expressivism is incompatible with the possibility of expressing certain kinds of negated normative judgements that further express nihilism or nihilistic doubt. And I think that because nihilism is a view that we must at least be able to entertain, this is a serious problem for expressivism.
