This book develops in detail the simple idea that assertion is the expression of belief. In it the author puts forward a version of 'probabilistic semantics' which acknowledges that we are not perfectly rational, and which offers a significant advance in generality on theories of meaning couched in terms of truth conditions. It promises to challenge a number of entrenched and widespread views about the relations of language and mind. Part I presents a functionalist account of belief, worked through a (...) modified form of decision theory. In Part II the author generates a theory of meaning in terms of 'assertibility conditions', whereby to know the meaning of an assertion is to know the belief it expresses. (shrink)

A comprehensive theory ofeven if needs to account for consequent ‘entailing’even ifs and in particular those of theif-focused variety. This is where the theory ofeven if ceases to be neutral between conditional theories. I have argued thatif-focusedeven ifs,especially if andonly if can only be accounted for through the suppositional theory ofif. Furthermore, a particular interpretation of this theory — the conditional assertion theory — is needed to account foronly if and a type of metalinguistic negation ofQ if P. We therefore (...) have evidence that the currently accepted approaches to conditionals are basically wrong about the semantic forms they attribute toif P, Q.11. (shrink)

This book offers a unique synthesis of past and current work on the structure, meaning, and use of negation and negative expressions, a topic that has engaged thinkers from Aristotle and the Buddha to Freud and Chomsky. Horn's masterful study melds a review of scholarship in philosophy, psychology, and linguistics with original research, providing a full picture of negation in natural language and thought; this new edition adds a comprehensive preface and bibliography, surveying research since the book's original publication.

A defense of material implication as implication.
