  2. Liar paradox - Wikipedia

    en.wikipedia.org/wiki/Liar_paradox

    If the liar is indeed lying, then the liar is telling the truth, which means the liar just lied.

It is still generally called the "liar paradox" although abstraction is made precisely from the liar making the statement.

    The Liar sentence, however, has neither an empty subject nor counter-instance. This fact creates obstacles for Athīr's view, who must show what is unique about the Liar sentence, and how the Liar sentence still could be only true or false in view of the "true" and "false" conditions set up in the universal proposition's description.

    en.wikipedia.org/wiki/Quine's_paradox

    Quine's paradox is a paradox concerning truth values, stated by Willard Van Orman Quine.

    The Pinocchio paradox arises when Pinocchio says "My nose grows now" and is a version of the liar paradox. [1] The liar paradox is defined in philosophy and logic as the statement "This sentence is false." Any attempts to assign a classical binary truth value to this statement lead to a contradiction, or paradox. This occurs because if the ...

    Thomas Fowler (1869) states the paradox as follows: "Epimenides the Cretan says, 'that all the Cretans are liars,' but Epimenides is himself a Cretan; therefore he is himself a liar. But if he is a liar, what he says is untrue, and consequently, the Cretans are veracious; but Epimenides is a Cretan, and therefore what he says is true; saying ...

    en.wikipedia.org/wiki/Lewis's_trilemma

    It is sometimes described as the "Lunatic, Liar, or Lord", or "Mad, Bad, or God" argument. It takes the form of a trilemma—a choice among three options, each of which is in some way difficult to accept. A form of the argument can be found as early as 1846, and many other versions of the argument preceded Lewis's formulation in the 1940s.
