|Definition: determination of the use of linguistic signs (words, symbols, connectives) for non-linguistic or linguistic objects. New definitions are not supposed to be creative, that is, they are to be derived from the use of the signs already employed. See also definability, conservativity, systems, theories, models, reference systems, context definition, explicit defnition, implicit definition._____________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. |

Prior: "tonk": do not do connections first and then meaning - then it cannot cause another pair of statements to be equivalent - N.B.: "analytical validity" cannot show this - BelnapVsPrior: (pro analytical validity): should not get mixed with the definition of existence, it first has to show how it works -> classical negation is illegitimate - negation-free fragment - Peirce's law.

Some words must be defined in non-linguistic ways.

Context definition: many logical words are explained by context definition. E.g. "All F are G" is equal to "Only F are G" This is a definition of the word "only"._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
