Quine’s paradox is as follows: “Yields falsehood when preceded by its quotation” yields falsehood when preceded by its quotation.
Bryan Bunch gives a great overview of this paradox (as well as many others) in his book, Mathematical Paradoxes and Fallacies (Mineola, New York: Dover Publications, 1982). As Bunch puts it:
[T]he Quine paradox is not dependent on the language in which it is expressed or its exact wording. In particular, the Quine paradox can be translated into a statement in mathematics. However, the odd thing that occurs in that translation (if it is carefully done) is that the result is no longer a paradox.
