Gottlob Frege's Über Sinn und Bedeutung (`On Sense and Reference'), has come to be seen, in the century since its publication in 1892, as one of the seminal texts of analytic philosophy. It, along with the rest of Frege's writings on logic and mathematics, came to mark out a whole new domain of inquiry. This volume bears witness to the continuing importance and influence of that agenda. It contains original papers written by leading Frege scholars for the conference held in 1992 in Karlovy Vary to celebrate the publication of Frege's essay. The fourteen essays show how the questions Frege discusses in that essay connect intimately with issues much debated in current philosophy of language and philosophy of mind.

A rich and informative biography of one of the most important and influential figures of analytic philosophy.

The nature of propositions and the cognitive value of names have been the focal point of philosophy of language for the last few decades. The advocates of the causal reference theory have favored the view that the semantic contents of proper names are their referents. However, Frege's puzzle about the different cognitive value of coreferential names has made this identification seem impossible. Geirsson provides a detailed overview of the debate to date, and then develops a novel account that explains our reluctance, even when we know about the relevant identity, to substitute coreferential names in both simple sentences and belief contexts while nevertheless accepting the view that the semantic content of names is their referents. The account focuses on subjects organizing information in webs; a name can then access and elicit information from a given web. Geirsson proceeds to extend the account of information to non-referring names, but they have long provided a serious challenge to the causal reference theorist.

Part of theLongman Library of Primary Sources in Philosophy, this edition of Frege's Foundations of Arithmetic is framed by a pedagogical structure designed to make this important work of philosophy more accessible and meaningful for undergraduates.

In this challenging and provocative analysis, Dale Jacquette argues that contemporary philosophy labours under a number of historically inherited delusions about the nature of logic and the philosophical significance of certain formal properties of specific types of logical constructions. Exposing some of the key misconceptions about formal symbolic logic and its relation to thought, language and the world, Jacquette clears the ground of some very well-entrenched philosophical doctrines about the nature of logic, including some of the most fundamental seldom-questioned parts of elementary propositional and predicate-quantificational logic. Having presented difficulties for conventional ways of thinking about truth functionality, the metaphysics of reference and predication, the role of a concept of truth in a theory of meaning, among others, Jacquette proceeds to reshape the network of ideas about traditional logic that philosophy has acquired along with modern logic itself. In so doing Jacquette is able to offer a new perspective on a number of existing problems in logic and philosophy of logic.

Gottlob Frege is considered the father of modern logic and one of the founding figures of analytic philosophy. His writings are difficult and deal with technical, asbtract concepts. The Routledge Philosophy Guidebook to Frege On Sense and Reference helps the student to get to grips with Frege's thought.

The nature of the information content of declarative sentences is a central topic in the philosophy of language. The natural view that a sentence like "John loves Mary" contains information in which two individuals occur as constituents is termed the naive theory, and is one that has been abandoned by most contemporary scholars. This theory was refuted originally by philosopher Gottlob Frege. His argument that the naive theory did not work is termed Frege's puzzle, and his rival account of information content is termed the orthodox theory. In this detailed study, Nathan Salmon defends a version of the naive theory and presents a proposal for its extension that provides a better picture of information content than the orthodox theory gives. He argues that a great deal of what has generally been taken for granted in the philosophy of language over the past few decades is either mistaken or unsupported, and consequently, much current research is focused on the wrong set of questions. Salmon dissolves Frege's puzzle as it is usually formulated and demonstrates how it can be reconstructed and strengthened to yield a more powerful objection to the naive theory. He then defends the naive theory against the new Frege puzzle by presenting an idea that yields both a surprisingly rich and powerful extension of the naive theory and a better picture of information content than that of the original orthodox theory.
