What is Tarski’s response to the liar paradox?
Tarski pointed out that the crucial, unacceptable assumption of the formal version of the Liar Argument is the self-reference allowed by any semantically closed language because any semantically closed language contains its own global truth predicate, and this leads to a contradiction.

The philosophical interest in self-reference is to a large extent centered around the paradoxes. A paradox is a seemingly sound piece of reasoning based on apparently true assumptions that leads to a contradiction.

In philosophy and logic, the classical liar paradox or liar’s paradox or antinomy of the liar is the statement of a liar that they are lying: for instance, declaring that “I am lying”. If the liar is indeed lying, then the liar is telling the truth, which means the liar just lied.

A statement’s logical form, in turn, would help resolve various problems of reference associated with the ambiguity and vagueness of natural language.
