This book presents an attempt to develop a theory of knowledge and a philosophy of mind using ideas derived from the mathematical theory of communication developed by Claude Shannon. Information is seen as an objective commodity defined by the dependency relations between distinct events. Knowledge is then analyzed as information caused belief. Perception is the delivery of information in analog form for conceptual utilization by cognitive mechanisms. The final chapters attempt to develop a theory of meaning by viewing meaning as (...) a certain kind of information-carrying role. (shrink)

This volume puts forward a distinct new theory of direct reference, blending insights from both the Fregean and the Russellian traditions, and fitting the general theory of language understanding used by those working on the pragmatics of natural language.

This book provides a novel interpretation of the ideas about language in Ludwig Wittgenstein's Philosophical Investigations. Travis places the "private language argument" in the context of wider themes in the Investigations, and thereby develops a picture of what it is for words to bear the meaning they do. He elaborates two versions of a private language argument, and shows the consequences of these for current trends in the philosophical theory of meaning.

Let us begin with a piece of intellectual history. The story begins in a period encapsulating the second world war – say the ‘40’s, give and take a bit. Around then, it began to be argued with force that an expression – e.g., an English one – while it well might mean something, does not say anything, and notably no one thing in particular. The principal behind the argument was surely J.L. Austin, though, I would claim, the same point was (...) argued in a somewhat different way by Wittgenstein. The intended point was not merely a grammatical one: we say of an expression that it means such and such, but not that it says such and such. Be that as it may, the main point was quite substantive: typically, an English expression is such that, with its meaning fixed, there are a variety of distinct things to be said in using it on some production of it or other.

The main thrust of the present work is to show why truth and truth bearers lie essentially beyond the descriptive reach of semantics, and to outline a theory of ...

Originally published in 1990, this book centres on a certain way of surveying a variety of theories of language, and on outlining a new proposal of meaning within the framework set by the survey. One of the key features of both survey and proposal is the insistence on the need to locate theories of language within a large framework that includes questions about the nature of thought and about general ontological questions as well. The book deals in an interconnected way (...) with both very general and specific issues. At one end of this spectrum there are discussions of the contrast between realist and nominalist ontologies, while at the other are analyses of specific lexical items of English. (shrink)
