Abstract

An account is given of Frege semantic theory and of its capacity to explain the ‘phenomenon of truth’, that is why there is the distinction between true sentences and false sentences. Some limits of Frege’s theory are stressed. Truth is meant of as ‘correspondence to facts’ and some attempts are made to insert a suitable notion of fact in the general frame of Frege’s theory. Among them, there is one which exploits Frege’s distinction between thought and apparent thought. The final step is a proposal to reconcile Frege’s theory of denotation with Russell-Wittgenstein’s theory of the representation of facts
