 It is interesting to observe that the elements of \(\mathcal{V}\) are sometimes referred to as quasi truth values. Siegfried Gottwald (1989: 2) explains that one reason for using the term ‘quasi truth value’ is that there is no convincing and uniform interpretation of the truth values that in many-valued logic are assumed in addition to the classical truth values the True and the False, an understanding that, according to Gottwald, associates the additional values with the naive understanding of being true, respectively the naive understanding of degrees of being true (cf. also the remark by Font (2009: 383) that “[o]ne of the main problems in many-valued logic, at least in its initial stages, was the interpretation of the ‘intermediate’ or ‘non-classical’ values”, et seq.). In later publications, Gottwald has changed his terminology and states that
