# Lexical Circularity **Domain:** Linguistics / Lexicography / Philosophy of Language **Doc Type:** Concept Node **Maturity:** Developed **Aliases:** Definitional Circularity, Dictionary Circularity **Related:** [[wiki/Semantics|Semantics]], [[wiki/Symbol Grounding Problem|Symbol Grounding Problem]], [[wiki/Semantic Holism|Semantic Holism]], [[wiki/Computational Linguistics|Computational Linguistics]] --- ## Definition **Lexical circularity is the condition in which words are defined through other words that are themselves defined within the same lexical system.** A reader can move from one definition to another, but definition alone never leaves the network of symbols and touches the object, action, sensation, or event the symbols describe. A finite dictionary whose entries use only words contained in that dictionary must eventually revisit earlier terms or depend upon a smaller vocabulary whose meanings the reader already possesses. Circularity does not make a dictionary useless. The dictionary contains a highly developed relational model: synonymy, contrast, category membership, implication, usage, and historical distinction preserve intelligence accumulated by generations of speakers and lexicographers. The limitation is that the lexical network cannot generate its own connection to the external world. It presupposes a reader whose perception, action, memory, culture, and prior language learning already supply enough grounding for definitions to work. ## Infinite Regress and Closure An infinite regress imagines definitions continuing without terminus; a finite dictionary converts that regress into a closed graph containing cycles. The logical shape is similar in both cases: if every symbol receives meaning only from another symbol, the system never reaches a non-symbolic anchor. Ordinary language escapes the practical paralysis because people do not learn every word from definitions. They learn through pointing, perception, imitation, bodily action, consequence, social correction, and repeated participation in a shared world. ## Corpus Function In [[livestreams/Opening Your Genius Through Language, Abstraction, and Manifesting - Livestream#Language Is an Executable Model of Reality|Language Is an Executable Model of Reality]], Bryant describes the dictionary as a closed synthetic model in which words depend upon other words. The point is double. The system contains intelligence because its relations preserve distinctions made by living minds; it remains closed because those relations alone cannot provide direct access to the physical reality they model. [[blog/20180903 - Before Westworld, the Ghost Was Already in the Machine|Before Westworld, the Ghost Was Already in the Machine]] places this lexical closure beside [[wiki/Artifact Intelligence|artifact intelligence]]: a dictionary stores relational intelligence symbolically, while a roof stores a learned relationship among rain, gravity, material, and shelter as physical constraint. The distinction was also an engineering problem in [[projects/Ten Years Building a Symbolic Language Engine|Ten Years Building a Symbolic Language Engine]]. That system represented English through phonological, semantic, taxonomic, corpus-derived, and associative relations, making the intelligence of the lexical network traversable while preserving the difference between relations inside the model and the experiences to which the relations ultimately refer. [[blog/20171004 - The Intelligence in the Dictionary|The Intelligence in the Dictionary]] follows the argument into [[wiki/Relational Reanimation|relational reanimation]]. A corpus preserves a wider field than explicit definitions alone; a language model can learn enough of that field to make inherited relations generative again, while the difference between generative competence and grounding remains intact. ## Key Insight **A dictionary can preserve an immense model of intelligence while remaining unable to supply the world that gives its symbols a referent.** ## Sources - Stevan Harnad, [“The Symbol Grounding Problem”](https://doi.org/10.1016/0167-2789(90)90087-6), *Physica D* 42 (1990): 335–346. - A.
