|Logical constants: logical constants are also called logical particles or connectives, they are e.g. “and”; “or”; “if”; “then”; “not”. The expression constant is used, because the meaning of the logical links cannot change also in the translation into other languages, but always remains. For example, if one was to try to replace "and" with "or" in the case of a translation, mistakes would arise which could be determined, even if the vocabulary of the foreign language is not entirely known._____________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. |
