摘要
This article focuses attention on the specification of language expressions in order to express statements having a truth value.Each specified expression(=value expression)introduced can be derived by adding a specification to an expression of the natural language(“Mario Rossi”—“Mario Rossi born in…on…”)or it can be associated with it without sharing any part of it(“water”-“H2O”).We can imagine different languages and different translation procedures from natural language;each procedure imposes a choice among different value expressions.There are two“windows”that the syntax of the specified expressions“opens up to the world”,so to speak;these are the following formulas:The value of/x/=x',where“x”,“x'”are names,/x/is true iffx',where“x”,“x'”are sentences.In the second formula categorical reductions and compositions of the specified expressions must have been performed.In cases where these passages are not available,we would remain with a syntactic expression of the type of sentences,but not,such as to exemplify the traditional definition of truth.

I would like to thank my colleague Andrea Bianchi,philosopher of the language of my Department,for discussions and critical remarks.By a coincidence of fate His name is among the most in need of specification,but he does not agree at all,as well as on the bartender’s beard and on the red color.
