In a rare first1, I was mistaken about the liar paradox. I laid out the solution to the liars paradox here. In particular, I said the following
This also explains why the sentence “this sentence is true,” is not paradoxical. The sentence “not not not not not not not not not not not…P,” for an infinite number of P’s is neither true nor false, but the statement “it is the case that it is the case that it is the case that it is the case that it is the case that…P,” would be true because it’s meaning is not infinitely alternating between two opposite statements.
What I should have realized is that the sentence “this sentence is true” is seemingly problematic. Is it true or is it false? That sentence is underspecified — much like the sentence “the man is tall” has no truth value if no man is specified. Thus, what I saw as a strength, avoiding saying this sentence is true has no truth value, was a weakness.
Now I tentatively endorse Huemer’s solution, but am uncertain.
Okay — second if you want to be precise about things — I have one other article that I no longer endorse, as I point out at the top of that article.
