This paper gives a characterization of those quasi-normal extensions of the modal system S4 into which intuitionistic propositional logic Int is embeddable by the Gödel translation. It is shown that, as in the normal case, the set of quasi-normal modal companions of Int contains the greatest logic, M*, for which, however, the analog of the Blok-Esakia theorem does not hold. M* is proved to be decidable and Halldén-complete; it has the disjunction property but does not have the finite model property. 相似文献

Does Physicalism lead to absurd results? Franz von Kutschera argued in his book ?Grundfragender Erkenntnistheorie” that the weakest version of physicalism, i. e. the thesis that physical facts determine all the facts there are, leads to the absurd result that events in a remote future determine the present brain states of a person. It is shown that the argument is flawed in several respects and that the absurd result is not a consequence of physicalism but of an auxiliary premiss of Kutschera's. 相似文献

From about the fourth to the tenth century Buddhist monks in China engaged in formal, semi-public, religious disputation. I describe the Indian origins of this disputation and outline its settings, procedures, and functions. I then propose that this disputation put its participants at risk of performative contradiction with Buddhist tenets about language and salvation, and I illustrate how some chinese Buddhists attempted to transcend these contradictions, subverting disputation through creative linguistic and extra- linguistic strategies. 相似文献

A Proof of Standard Completeness for Esteva and Godo's Logic MTL 总被引:7,自引:0,他引:7
In the present paper we show that any at most countable linearly-ordered commutative residuated lattice can be embedded into a commutative residuated lattice on the real unit interval [0, 1]. We use this result to show that Esteva and Godo's logic MTL is complete with respect to interpretations into commutative residuated lattices on [0, 1]. This solves an open problem raised in. 相似文献

Certain extensions of Nelson's constructive logic N with strong negation have recently become important in arti.cial intelligence
and nonmonotonic reasoning, since they yield a logical foundation for answer set programming (ASP). In this paper we look
at some extensions of Nelson's .rst-order logic as a basis for de.ning nonmonotonic inference relations that underlie the
answer set programming semantics. The extensions we consider are those based on 2-element, here-and-there Kripke frames. In
particular, we prove completeness for .rst-order here-and-there logics, and their minimal strong negation extensions, for
both constant and varying domains. We choose the constant domain version, which we denote by QNc5, as a basis for de.ning a .rst-order nonmonotonic extension called equilibrium logic. We establish several metatheoretic
properties of QNc5, including Skolem forms and Herbrand theorems and Interpolation, and show that the .rst-oder version of equilibrium logic can be used as a foundation for answer set inference. 相似文献

This paper develops a new proof method for two propositional paraconsistent logics: the propositional part of Batens' weak
paraconsistent logic CLuN and Schütte's maximally paraconsistent logic Φv. Proofs are de.ned as certain sequences of questions. The method is grounded in Inferential Erotetic Logic. 相似文献
