Self-reference is a phenomenon in which a statement, concept, action, or system refers to itself. In other words, it is a situation in which an expression can function simultaneously as both a function and an argument of that function.
Self-reference can:
– lead to logical paradoxes (for example, “This statement is false”);
– be used for self-description and self-identification;
– serve as a tool for analyzing thought, language, and consciousness.
Key Aspects and Examples
1. Logic and Mathematics
Self-referential constructions often give rise to paradoxes, such as the liar paradox (“I am lying”), as well as statements that refer to their own number or their own truth. Such cases can lead to a loss of predicativity and problems of formalization.
2. Psychology: The Self-Reference Effect
In cognitive psychology, the self-reference effect is well known: people remember and process information better when it relates to them personally (for example, words describing a person’s own qualities).
3. Language and Art
In language, self-reference appears in sentences that describe themselves (for example, “This sentence has five words”). In art, it appears in works that depict their own creation or incorporate the author and the creative process into the very structure of the work.
Synonyms and Related Terms
- self-relatedness;
- self-referencing (more often in psychology);
- self-referentiality;
- self-description.
Conclusion
Self-reference can be both a source of logical errors and paradoxes and a foundation for self-description, self-identification, and personal self-awareness.
