|Object language, philosophy: The object language is the language in which something is said or written in a situation. In contrast, comments and evaluations of what is said or written are invariably written in a metalanguage when the original utterance is mentioned or quoted in it. Metalanguage is thus language about language. Object language is used to mention objects, metalanguage is used to mention linguistic ways of expression. See also metalanguage, mention, use, quotation._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them. Instead, they are intended to give a short introduction to the contributions below. – Lexicon of Arguments. |

Axiom/(s): not part of the object language.
Schematic formula: can be part of the object language - Field: this detects the concept of truth better._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
