A strange loop is a case of Self-reference which affects (or even damages) the original item, possibly causing a Paradox . EXAMPLES For example, Abbie Hoffman once wrote a book called '' Steal This Book '', which thereby tried to undermine its own sales in bookstores. The band System Of A Down did the same later with the album '' Steal This Album! ''. The Liar Paradox and Russell's Paradox also involve strange loops. In Art , M.C. Escher's Drawing Hands is an example of a strange loop, as is René Magritte's ''The Treachery of Images''. Strange loops often involve violation of Hierarchies , in which (for example) a computer program (rather than a person) writes computer programs. This, by itself, is not enough to be a strange loop (it is merely self reference, and is common practice for a Compiler ). An example of a strange loop in software is a Quine , which is a program that produces a new version of itself without any input from the outside. Metamorphic Code is similar. Strange loops are frequently intriguing or even humorous. A sketch on '' Late Night With Conan O'Brien '' once had Conan (seemingly spontaneously) become upset with a cue-card holder and tell him to leave the set; immediately, the cue-card holder was shown, holding a card with Conan's "you'd better leave" line written on it. The concept of a strange loop was proposed and extensively discussed by Douglas Hofstadter in '' Gödel, Escher, Bach ''. SEE ALSO |
