"Semantic Antinomies outside semantically closed languages:  A critique of Tarski’s analysis of the liar antinomy"


Tarski’s famous analysis of the liar antinomy comes to the conclusion: The liar can be constructed in a language if, and only if, this language is semantically closed. My main point is to show that Tarski’s conclusion is false and that his analysis is aporetic. The conclusion is false because the liar can be constructed in languages that are not semantically closed; the analysis is aporetic because there is no language in which the analysis can be expressed consistently.
