    • Self-reference occurs in natural or formal languages when a sentence, idea or formula refers to itself. The reference may be expressed either directly—through some intermediate sentence or formula—or by means of some encoding. In philosophy, it also refers to the ability of a subject to speak of or refer to i ... Read »

    • Circular reference

    • A circular reference is a series of references where the last object references the first, resulting in a closed loop. A circular reference is not to be confused with the logical fallacy of a circular argument. Although a circular reference will often be unhelpful and reveal no information, such as two entries in ...

    • Corecursion

    • In computer science, corecursion is a type of operation that is dual to recursion. Whereas recursion works analytically, starting on data further from a base case and breaking it down into smaller data and repeating until one reaches a base case, corecursion works synthetically, starting from a base case and building i ...

    • Fumblerules

    • A fumblerule is a rule of language or linguistic style, humorously written in such a way that it breaks this rule. Fumblerules are a form of self-reference. The science editor George L. Trigg published a list of such rules in 1979. The term fumblerules was coined in a list of such rules compiled by William Safire on S ... Read »

    • Impredicativity

    • In mathematics and logic, a self-referencing definition is called impredicative. Roughly speaking, a definition is said to be impredicative if it invokes (mentions or quantifies over) the set being defined, or (more commonly) another set which contains the thing being defined. There is no generally accepted precise def ... Read »

    • Indirect self-reference

    • Indirect self-reference describes an object referring to itself indirectly. For example, define the function f such that f(x) = x(x). Any function passed as an argument to f is invoked with itself as an argument, and thus in any use of that argument is indirectly referring to itself. This example is similar to the Sc ... Read »

    • Liar paradox in early Islamic tradition

    • Many early Islamic philosophers and logicians discussed the liar paradox. Their work on the subject began in the 10th century and continued to AthÄ«r al-DÄ«n al-AbharÄ« and Nasir al-Din al-Tusi of the middle 13th century and beyond. Although the Liar paradox has been well known in Greek and Latin traditions, the ... Read »

    • Non-well-founded set theory

    • Non-well-founded set theories are variants of axiomatic set theory that allow sets to contain themselves and otherwise violate the rule of well-foundedness. In non-well-founded set theories, the foundation axiom of ZFC is replaced by axioms implying its negation. The study of non-well-founded sets was initiated by Dmi ... Read »

    • Recursion

    • Recursion occurs when a thing is defined in terms of itself or of its type. Recursion is used in a variety of disciplines ranging from linguistics to logic. The most common application of recursion is in mathematics and computer science, where a function being defined is applied within its own definition. While this ap ... Read »

    • Recursive acronym

    • A recursive acronym is an acronym that refers to itself. The term was first used in print in 1979 in Douglas Hofstadter's book Gödel, Escher, Bach: An Eternal Golden Braid, in which Hofstadter invents the acronym GOD, meaning "GOD Over Djinn", to help explain infinite series, and describes it as a recursive acronym. ...

    • Self-perpetuation

    • Self-perpetuation, the capability of something to cause itself to continue to exist, is one of the main characteristics of life. Organisms' capability of reproduction leads to self-perpetuation of the species, if not to the individual. Populations self-perpetuate and grow. Entire ecosystems show homeostasis, and thus p ...

    • Self-referential encoding

    • Every day, people are presented with endless amounts of information, and in an effort to help keep track and organize this information, people must be able to recognize, differentiate and store information. One way to do that is to organize information as it pertains to the self. The overall concept of self-reference s ... Read »

    • Universal set

    • In set theory, a universal set is a set which contains all objects, including itself. In set theory as usually formulated, the conception of a universal set leads to a paradox (Russell's paradox) and is consequently not allowed. However, some non-standard variants of set theory include a universal set. It is often symb ... Read »
