Theorem 6.5 Let τ be a modal similarity type. Any normal modal logic in a language for τ has the finite model property iffit has the finite frame property. Definition 6.6 (Strong Finite Model Property) Let Λ be a normal modal logic, M a set of finitely based models such that Λ = ΛM, and f a function mapping natural numbers to natural numbers.

Modal logic is the logic of necessity and possibility, and by extension of analogously paired notions like validity and consistency, obligation and permission, the known and the not-ruled-out. This a first course in the area. A solid background in first-order logic is essential. Modern Origins of Modal Logic. First published Tue Nov 16, 2010; substantive revision Mon May 8, 2017. Modal logic can be viewed broadly as the logic of different sorts ofmodalities, or modes of truth: alethic (“necessarily”),epistemic (“it is known that”), deontic (“it oughtto be the case that”), or temporal (“it has been the casethat”) among others. The idea is that modal calculi describe several possible worlds at once, instead of just one.

Modal logic

Modal logic is most commonly interpreted in terms of possible world semantics or Kripke structures. This semantics carries over naturally to dynamic logic by interpreting worlds as states of a computer in the application to program verification, or states of our environment in applications to linguistics, AI, etc.

Recall that a pointed Kripke frame is a Kripke frame (W, R) with a designated world w 0 ∈ W, and a sentence is valid in Alethic modal logic (modal logic in the narrow sense) interprets the strong and the weak modal operator as “necessarily” and “possibly”, respectively.

| Adlibris Alethic modal logic (modal logic in the narrow sense) interprets the strong and the weak modal operator as “necessarily” and “possibly”, respectively. Necessity and possibility, however, can be understood differently. Se hela listan på iep.utm.edu While predicate logic is especially interesting to mathematicians, modal logic is especially interesting to philosophers because many of the most interesting arguments in the history of philosophy—arguments about the nature and existence of God, free will, the soul, and much more—are modal in nature and can only be analyzed in a deep way using the techniques of modal logic. This is a thorough treatment of first-order modal logic. The book covers such issues as quantification, equality (including a treatment of Frege's morning star/evening star puzzle), the notion of existence, non-rigid constants and function symbols, predicate abstraction, the distinction between nonexistence and nondesignation, and definite descriptions, borrowing from both Fregean and Modal definition is - of or relating to modality in logic.

Whether it is also valid with legal or moral necessity is a qu Elements of modal logic were in essence already known to Aristotle (4th century B.C.) and became part of classical philosophy. Modal logic was formalized for the first time by C.I. Lewis , who constructed five propositional systems of modal logic, given in the literature the notations S1–S5 (their formulations are given below). Other systems of modal logic were then constructed and investigated. The term modal logic refers to an enrichment of standard formal logic where the standard operations (and, or, not, implication and perhaps forall, etc.) are accompanied by certain extra operations – called modal operators and often denoted by “ \lozenge ” and “ \Box ” or similar – such that for p p any proposition the expression p \Box p is a new proposition whose interpretation is roughly as “ p p holds (only) in some mode” or “ p p holds (only) in a certain way”, such to Modal Logic W.Gunther Propositional Logic Our Language Semantics Syntax Results Modal Logic Our language Semantics Relations Soundness Results Modal Models De nition A model M = hW;R;Vi is a triple, where: W is a nonempty set.
