Abstract

Available from UMI in association with The British Library. Requires signed TDF. ;This work pursues certain themes in the rise and development of analytic philosophy, focussing in particular on the relationship between Aristotelian and Fregean logic, and the emergence and evolution of interest in questions of meaning, with reference to Frege and Wittgenstein. ;In the introductory chapter I consider the general relationship between analytic philosophy and the history of philosophy, suggesting the need for a closer examination of the 'paradigm shift' from syllogistic theory to modern logic. In Part One I undertake this examination, with a chapter outlining the development, nature and purpose of Aristotle's logical theory, followed by a chapter describing Frege's achievement in the Begriffsschrift. My central concern here is with the emergence of a conception of sense--as grounded in the notion of logical equivalence. Aristotle, I argue, had no such conception; and it only emerged as Frege was led to reflect on the differences between his own logical system and traditional logic. ;In Part Two I consider the tightening of the 'bonds of sense' which Frege created, looking first at Frege's logicist project and then at Wittgenstein's Tractatus . I describe the epistemological motivation of Frege's work and the way that this led him to distinguish between Sinn and Bedeutung, and I argue that there is a fundamental tension in his mature thought between a semantic and an epistemic conception of sense. This tension was ironed out, however, in the early work of Wittgenstein, who rigorously thought through the implications of the semantic conception. I trace the evolution of his early ideas, in the framework provided by Frege and Russell, and explain how his saying/showing distinction shaped both his account of logic and his picture theory of language. ;In Part Three I discuss Wittgenstein's later philosophy, showing how it developed in response to problems he later perceived in both his own earlier work and the writings of Frege. I describe the shift from simples to samples, and explain his conception of meaning as use and his remarks on rule-following . In the final chapter, I consider the implications of our discussion of sense for the issues as to the nature of logic and the role of philosophical analysis
