|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. |
And/conjunction/definition/logical constants/Dummett: from assertion of P and assertion of Q - not circular: because for that one does not need the concept of conjunction. - E.g. like the dog that is trained to respond to a bell only together with light signal.
Or/disjunction/Problem: for "or" no such explanation in bivalent logic. - It may be that we can assert "P or Q" without being able to assert one individually without the other.
Right explanation: through the fact that makes one of two true - knowledge or recollection does not matter._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
