Gettier Problems, C-Justifications, and C-Truth-Grounds

This paper is a continuation of Usberti (forthcoming), in which I proposed, as the key notion of an anti-realist theory of the meaning of empirical statements, the theoretical notion of C-justification for A, where A is an empirical statement that can be translated into a sentence of first order logic. Here I suggest, first, an extension of the definition of C-justification to statements of the forms “s justifiedly believes that A” and “s knows that A”; second, a characterization of the assertibility conditions of all the statements for which the notion of C-justification has been defined. The definition of C-justifications for “s knows that A” will involve and an analysis of Gettier problems and the definition of the notion of C-truth-ground of A.
