Fisher, Jennifer, and . On the Philosophy of Logic

2007, Cengage Learning.

Publisher’s Note: Jennifer Fisher’s On the Philosophy of Logic explores questions about logic often overlooked by philosophers. Which of the many different logics available to us is right? How would we know? What makes a logic right in the first place? Is logic really a good guide to human reasoning? An ideal companion text for any course in symbolic logic, this lively and accessible book explains important logical concepts, introduces classical logic and its problems and alternatives, and reveals the rich and interesting philosophical issues that arise in exploring the fundamentals of logic.

Comment: This book provides an introduction to some traditional questions within philosophy of logic. Moreover, it presents some non-classical logics. It includes an introduction to formal classical logic, so no previous technical knowledge is required. Adequate for a first course on philosophy of logic, either as main or further reading.

Sher, Gila, and . Logical Quantifiers

2012, In D. Graff Fara & G. Russell (eds.), Routledge Companion to Philosophy of Language. Routledge. pp. 579-595.

Abstract: This article offers a logical, linguistic, and philosophical account of modern quantification theory. Contrasting the standard approach to quantifiers (according to which logical quantifiers are defined by enumeration) with the generalized approach (according to which quantifiers are defined systematically), the article begins with a brief history of standard quantifier theory and identifies some of its logical, linguistic, and philosophical strengths and weaknesses. It then proceeds to a brief history of generalized quantifier theory and explains how it overcomes the weaknesses of the standard theory. One of the main philosophical advantages of the generalized theory is its philosophically informative criterion of logicality. The paper describes the work done so far in this theory, highlights some of its central logical results, offers an overview of its main linguistic contributions, and discusses its philosophical significance.

Comment: This paper is adequate for an advanced course on philosophy of logic or for a specialised course on quantification. It provides a presentation and a comparison of two different conceptions of quantification: standard modern quantification and generalised quantification. Interestingly, it presents the virtues and drawbacks of each of them from three different points of view: logical, linguistic and philosophical. Moreover, it puts special emphasis on the theme of which quantifiers are to count as logical by focusing on the criterion of logicality which is available for the generalized conception. It presupposes some knowledge of predicate logic as well as of set theory.
