First published in 1978, this reissue presents a seminal philosophical work by professor Putnam, in which he puts forward a conception of knowledge which makes ethics, practical knowledge and non-mathematic parts of the social sciences just as much parts of 'knowledge' as the sciences themselves. He also rejects the idea that knowledge can be demarcated from non-knowledge by the fact that the former alone adheres to 'the scientific method'. The first part of the book consists of Professor Putnam's John Locke (...) lectures, delivered at the University of Oxford in 1976, offering a detailed examination of a 'physicalist' theory of reference against a background of the works of Tarski, Carnap, Popper, Hempel and Kant. The analysis then extends to notions of truth, the character of linguistic enquiry and social scientific enquiry in general, interconnecting with the great metaphysical problem of realism, the nature of language and reference, and the character of ourselves.

A natural question to raise about words—or about their mental analogue, concepts—is: in virtue of what facts do they refer to whatever it is that they refer to? In virtue of what does the word ‘insanity’ refer to insanity, the word ‘entropy’ refer to entropy, and so forth? There is a view called “disquotationalism” according to which this question is misconceived. I’ll have something to say about that later. But putting disquotationalism aside for now, it would seem that this question (...) about words or concepts needs an answer. And the only kind of answer we can take seriously is a naturalistic answer: the Brentanian answer that words or concepts refer by virtue of irreducibly mental connections between the mind and the world is not a serious contender. What if no naturalistic answer is possible? If we put disquotationalism aside, the only conclusion to be drawn is that the assumption that ‘insanity’ and ‘entropy’ determinately refer to insanity and to entropy is an illusion. (shrink)

Stephen Schiffer presents a groundbreaking account of meaning and belief, and shows how it can illuminate a range of crucial problems regarding language, mind, knowledge, and ontology. He introduces the new doctrine of 'pleonastic propositions' to explain what the things we mean and believe are. He discusses the relation between semantic and psychological facts, on the one hand, and physical facts, on the other; vagueness and indeterminacy; moral truth; conditionals; and the role of propositional content in information acquisition and explanation. (...) This radical new treatment of meaning will command the attention of everyone who works on fundamental questions about language, and will attract much interest from other areas of philosophy.

Presenting a selection of thirteen essays on various topics at the foundations of philosophy--one previously unpublished and eight accompanied by substantial new postscripts--this book offers outstanding insight on truth, meaning, and propositional attitudes; semantic indeterminacy and other kinds of "factual defectiveness;" and issues concerning objectivity, especially in mathematics and in epistemology. It will reward the attention of any philosopher interested in language, epistemology, or mathematics.

This second edition includes a new Afterword by the author.

Even if non-cognitivists about some subject-matter can meet Geach’s challenge to explain how there can be valid implications involving sentences which express non-cognitive attitudes, they face a further problem. I argue that a non-cognitivist cannot explain how, given a valid argument whose conclusion expresses a belief and at least one of whose premises expresses a non-cognitive attitude, it could be reasonable to infer the conclusion from the premises.
