On Quantified Modal Logic
Propositional modal logic is a standard tool in many disciplines, but first-order modal logic is not. There are several reasons for this, including multiplicity of versions and inadequate syntax. In this paper we sketch a syntax and semantics for a natural, well-behaved version of first-order modal logic, and show it copes easily with several familiar difficulties. And we provide tableau proof ...
متن کاملQuantified Modal Logic on the Rational Line
In the topological semantics for propositional modal logic, S4 is known to be complete for the class of all topological spaces, for the rational line, for Cantor space, and for the real line. In the topological semantics for quantified modal logic, QS4 is known to be complete for the class of all topological spaces, and for the family of subspaces of the irrational line. The main result of the ...
متن کاملSemantics and Ontology in Quantified Modal Logic
Philosophical logic studies the relationships between philosophical stands and logic as well as the logical and philosophical consequences that can be drawn from these connections. There is a good deal of results in this area spread over the second half of last century and, these days, there seems to be a renewed interest in this topic perhaps due to the introduction of ontological concerns in ...
متن کاملCounterpart Semantics for Quantified Modal Logic
In this paper we deal with the semantics for quantified modal logic, QML in short, and their philosophical relevance. In the first part we introduce Kripke semantics for the first-order modal language L= with identity, then we consider some unsatisfactory features of this account from an actualist point of view. In addition, we show that the calculus QE .K + BF on free logic, with the Barcan fo...
متن کاملLabelled Proofs for Quantified Modal Logic
In this paper we describe a modal proof system arising from the combination of a tableau-like classical system, which incorporates a restricted (“analytic”) version of the cut rule, with a label formalism which allows for a specialised, logic-dependent unification algorithm. The system provides a uniform proof-theoretical treatment of first-order (normal) modal logics with and without the Barca...
