The topic of true and false intent has been more or less ignored within the field of legal psychology. This is remarkable considering the frequency and importance of situations calling for assessments of whether a person is lying or telling the truth about his or her intentions (e.g., when crossing a border). There were four aims to the present paper. The first was to outline a psycho-legal res...

This paper deals with topos-theoretic truth-value valuations of quantum propositions. Concretely, a mathematical framework of a specific type of modal approach is extended to the topos theory, and further, structures of the obtained truth-value valuations are investigated. What is taken up is the modal approach based on a determinate lattice D(e,R), which is a sublattice of the lattice L of all...

Wavelet based logic is a form of many valued logic, it deals with reasoning that is approximate rather than fixed and exact. Compared to traditional binary sets (where variables may take on true or false values) fuzzy logic variables may have a truth value that ranges in degree between 0 and 1. Fuzzy logic has been extended to handle the concept of partial truth, where the truth value may range...

A method of supervaluation for Kripke's theory of truth is presented. It di ers from Kripke's own method in that it employs trees; results in a compositional semantics; assigns the intuitively correct truth values to the sentences of a particularly tricky example of Gupta's; and it is argued is acceptable as an explication of the correspondence theory of truth. In his (1982) Gupta presents the ...

Different many-valued logic programming frameworks have been proposed to manage uncertain information in deductive databases and logic programming. A feature of these frameworks is that they rely on a predefined assumption or hypothesis, i.e. an interpretation that assigns the same default truth value to all the atoms of a program, e.g. in the open world assumption, by default all atoms have un...

in this article, the author deals with the critical study of rorty and gadamer's doctrines on truth through analyzing its undesirable epistemological and political consequences. rorty denies truth and believes that it is merely the indicator of sentences specification. but gadamer does not deny truth and believes it is as event of appearance which flourishes from within the dialogue and ma...

The Liar Paradox arises when a person stands up and says, “This assertion is false.” Is the speaker telling the truth or telling a lie? At first blush, it seems that the situation is paradoxical: if he is telling the truth, then he is not; if he is not telling the truth, then he is. In fact, that first blush lasted for almost two thousand years. First formulated by the ancient Greeks, the puzzl...

This paper investigates the relationship between reality and model, information and truth. It will argue that meaningful data need not be true in order to constitute information. Information to which truth value cannot be ascribed, partially true information or even false information can lead to an interesting outcome such as technological innovation or scientific breakthrough. In the research ...

Abstract We present a method that generates two-sided sequent calculi for four-valued logics like first degree entailment ( FDE ). (We say logic is FDE-like if it has finitely many operators of finite arity, including negation, and all its are truth-functional over the four truth-values ‘none’, ‘false’, ‘true’, ‘both’, where ‘true’ ‘both’ designated.) First, we show every n -ary operator ⋆ trut...
