{"product_id":"books-first-order-modal-logic-by-melvin-fitting","title":"First-Order Modal Logic","description":"This revised edition of the highly recommended book \"First-Order Modal Logic\", originally published in 1998, contains both new and modified chapters reflecting the latest scientific developments. Fitting and Mendelsohn present a thorough treatment of first-order modal logic, together with some propositional background. They adopt throughout a threefold approach. Semantically, they use possible world models; the formal proof machinery is tableaus; and full philosophical discussions are provided of the way that technical developments bear on well-known philosophical problems. The book covers quantification itself, including the difference between actualist and possibilist quantifiers; equality, leading to a treatment of Frege's morning star\/evening star puzzle; the notion of existence and the logical problems surrounding it; non-rigid constants and function symbols; predicate abstraction, which abstracts a predicate from a formula, in effect providing a scoping function for constants andfunction symbols, leading to a clarification of ambiguous readings at the heart of several philosophical problems; the distinction between nonexistence and nondesignation; and definite descriptions, borrowing from both Fregean and Russellian paradigms. Review of the First Edition: \"This Text is an excellent and most useful volume. It is pitched  correctly: the exercises are just right... It sets a high standard for  anything following. It is to be highly recommended.\"  (Bulletin of Symbolic Logic, 8:3)","brand":"World of Books ","offers":[{"title":"Default Title","offer_id":53671263338769,"sku":null,"price":0.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9783031407130.jpg?v=1781515545","url":"https:\/\/www.worldofbooks.com\/en-gb\/products\/books-first-order-modal-logic-by-melvin-fitting","provider":"World of Books ","version":"1.0","type":"link"}
