The book presents a thoroughly elaborated logical theory of generalized truth-values understood as subsets of some established set of (basic) truth values. After elucidating the …
In Belnap's useful 4-valued logic, the set 2={T, F} of classical truth values is generalized to the set 4=℘(2)={∅,{T},{F},{T, F}}. In the present paper, we argue in favor of extending this …

In this paper we will consider the existing notions of bilateralism in the context of proof- theoretic semantics and propose, based on our understanding of bilateralism, an extension …

The aim of this paper is to obtain a theoretical foundation of inconsistency-tolerant (or paraconsistent) reasoning by presenting a comprehensive study of the structural proof …
We consider a logic which is semantically dual (in some precise sense of the term) to intuitionistic. This logic can be labeled as “falsification logic”: it embodies the Popperian …

In this introductory chapter, we show how Gottlob Frege's notion of a truth value has become part of the standard philosophical and logical terminology. Nowadays, the notion of a truth …
Abstract According to Suszko's Thesis, there are but two logical values, true and false. In this paper, R. Suszko's, G. Malinowski's, and M. Tsuji's analyses of logical twovaluedness are …

This paper highlights the importance of a strategy for semantic analysis initiated by J. Michael Dunn, known in the literature as the “American Plan.” The key insight of the plan …

The knowability paradox is an instance of a remarkable reasoning pattern (actually, a pair of such patterns), in the course of which an occurrence of the possibility operator, the diamond …
