5. Theory of Logic / L. Paradox / 6. Paradoxes in Language / a. The Liar paradox

19187	The Liar makes us assert a false sentence, so it must be taken seriously [Tarski]
	Full Idea: In my judgement, it would be quite wrong and dangerous from the point of view of scientific progress to depreciate the importance of nhtinomies like the Liar Paradox, and treat them as jokes. The fact is we have been compelled to assert a false sentence.
	From: Alfred Tarski (The Semantic Conception of Truth [1944], 07)
	A reaction: This is the heartfelt cry of the perfectionist, who wants everything under control. It was the dream of the age of Frege to Hilbert, which gradually eroded after Gödel's Incompleteness proof. Short ordinary folk panic about the Liar?
