Benson Mates on Identity - Dictionary of Arguments
I 193 Identity/"is"/analytical/intensional/Mates: it is debatable whether "A is A" must be regarded as formal analytically or analytically because of the sense of "is". - Like statements from scheme. Example: If A is warmer than B and B is warmer than C, then A is warmer than C analytically because of the sense of "is warmer than". >Analyticity/Synthetic, >Analytically true, >Synthetic. he dispute is whether "is" can be regarded as a logical constant such as "not" etc, or as a belonging to the non-logical vocabulary. >Is, >Logical constants, >Connectives, cf. >Lexicon/Quine, >Copula. Language L: here was "is" non-logic - that was arbitrary. >Everyday language. I 19 if not -logic, then independent theory of identity possible. >Identity. On the other hand: if "is" logical constant (which means the relation of identity above this area) we construct with that a new language. I 200 Identity/Frege/Mates: "a = a" and "a = b": Difference sense/meaning- E.g. "7 + 5 = 12" does not mean the same as "The expressions" 7 + 5 "and" 12 " refer to the same object ". >Metalanguage, >Object language, >Reference, >Levels/order, >Levels of Description. Solution/Frege: the second is a synthetic truth about language ((s) metalinguistically) - the first an analytic truth about numbers - ((s) object language) - identity/Mates: there is not the relation of identity! - They are different from area to area - ((s) intensional/extensional). >Domains._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
