In Popular Culture
The liar paradox is occasionally used in fiction to shut down artificial intelligences, who are presented as being unable to process the sentence. In Star Trek: The Original Series episode I, Mudd, the Liar paradox is used by the characters of Captain Kirk and Harry Mudd to confuse and ultimately disable an android, and in the 1973 Doctor Who serial The Green Death, the Doctor temporarily stumps the insane Computer BOSS by asking it "If I were to tell you that the next thing I say would be true, but the last thing I said was a lie, would you believe me?" In the 2011 videogame Portal 2, GLaDOS attempts to use the "this sentence is false" paradox to defeat the naïve artificial intelligence Wheatley, but he responds saying "Um, true. I'll go with true. There, that was easy." and is unaffected.
Comedian George Carlin says "The following statement is true: the preceding statement is false!" within a list of announcements on his 1981 comedy album A Place For My Stuff.
In Lois McMaster Bujold's Vorkosigan Saga, Cordelia Naismith frequently muses on the axiom "all Cretans are liars" in her inner monologue.

Famous quotes containing the words popular and/or culture:
“If our entertainment culture seems debased and unsatisfying, the hope is that our children will create something of greater worth. But it is as if we expect them to create out of nothing, like God, for the encouragement of creativity is in the popular mind, opposed to instruction. There is little sense that creativity must grow out of tradition, even when it is critical of that tradition, and children are scarcely being given the materials on which their creativity could work”
—C. John Sommerville (20th century)
“The first time many women hold their tiny babies, they are apt to feel as clumsy and incompetent as any man. The difference is that our culture tells them they’re not supposed to feel that way. Our culture assumes that they will quickly learn how to be a mother, and that assumption rubs off on most women—so they learn.”
—Pamela Patrick Novotny (20th century)
