Self-reference is the property of a sentence, utterance, symbol, or system indicating or referring to “itself.” Studied in logic, philosophy, mathematics, computer science, literature, and other fields, it is investigated as a source of contradictions (paradoxes) and a basis for advanced recursive systems (self-referential systems). Main characteristics and examples of self-reference Definition: a symbol or description having “itself” as its referent. Self-reference paradox: Logical contradictions caused by self-reference. A famous example is the liar paradox: if “This sentence is false” is true, it becomes false, and if false, it becomes true. Literature/art: A technique of referring within a work to the work itself (for example, Don Quixote addressing readers of Don Quixote within the story). Technology and sociology: Recursive processing in computer programs and “autopoietic” structures in which social systems monitor and observe their own workings. Museum and art information Specific examples of paradoxes Liar paradox: “I am lying right now.” Russell's paradox: Does “the set of sets not containing themselves” contain itself? (Collapse of logical hierarchy.) Taiheiyo Newspaper, digital edition Aspects by field Mathematics and logic: The concept underlying Gödel's incompleteness theorem (“This sentence cannot be proved”). Law: The property of law defining its own validity and grounds.
