A while ago there was a discussion on this list about the seriousness
of the liar paradox. It seemed to be framed as a criticism of my
book "Truth & Assertibility", which begins with a discussion of this
topic (the question being, I think, why I would waste time on such a
triviality).
(Not all reactions to my book were negative. May I mention that Math
Reviews hailed my "fresh and productive approach" as "a major
contribution"?)
This is just to say that I have written a short paper on the subject
titled "The liar paradox is a real problem". It is available on the
arXiv here:
https://arxiv.org/abs/1702.03875
The key takeaway: "whatever simple idea you have for an easy resolution
of the liar paradox --- we've tried it, and it doesn't work."
