In this paper we associate the three concepts of language, thinking, and meaning with Fuzzy Sets and Systems and Fuzzy Logic. We present some developments in 20th century history of science and of humanities that show deep links between these concepts and we give a proposal for a fuzzy theoretical interpretation...

In this paper we discuss the multifaceted nature of vagueness, the limits of (standard) set theory in dealing with the foundational aspects that a really innovating theory of vagueness should manifest, and the difficulties in outlining the possible features that such a type of new formalism should exhibit...

Wisdom is an ancient concept, that experiences a renaissance since the last century throughout several scientific communities. In each of them it is interpreted in rather different ways - from a key ability to succesful aging to a human peak perfomance transcending mere knowledge. As a result, miscellaneous...

In this paper we used a two-step procedure for the numerical translation of verbal frequency expressions of the response scale of a questionnaire (STAI-T). In an empirical study, 70 participants estimated numerical equivalents for verbal frequency expressions, data was modeled, and fuzzy membership functions...

This paper takes into account the Wittgenstein's idea of family resemblance as a particular crisp relation between some fuzzy sets, that is, between some representations of predicates use from its use. It is shown that all uses of the same predicate actually do have some kind of family resemblance, that...

The impressive practical applications is one of the main reasons of success of Fuzzy Logic. The Computational Theory of Perceptions (CTP) is an extension of this theory that has not yet reached the same level of applicability. We believe that a review of the fundamentals of CTP from a epistemological...

Different types of inexactness can be represented by fuzzy sets: vagueness, where there are no precise boundaries, ambiguity, when more than one distinguishable concept is described, generality, such that a word applies to a variety of situations, and ambivalence, where conflicting valuations can coexist....

In light of recent research and empirical findings a new view on emotion and affect has surfaced. Within this view `feeling' (core affect) is separated from Ëmotion' (psychological construction). This model appears to be a good candidate for a computation model of affect and emotion. We argue that fuzzy...
