Current philosophical studies of the implications of a "minimalist" theory of truth reveal how problems otherwise unnoticed are arisen by the issue of true or false. As catalyzer of linguistic problems, this issue appears even today as a dark mirror wherein language reflects its profound enigmas and unavoidable uncertainties.

From the analysis of some proposals regarding Frege's reasoning about the indefinibility of the truth and supported on different considerations developed by J. Simon on this matter, this project proposes a new interpretation of the relations that the different theories of the truth have among themselves.
