In informal terms, abductive reasoning involves inferring the best or most plausible explanation from a given set of facts or data. It is a common occurrence in everyday life and crops up in such diverse places as medical diagnosis, scientific theory formation, accident investigation, language understanding, and jury deliberation. In recent years, it has become a popular and fruitful topic in artificial intelligence research. This volume breaks new ground in the scientific, philosophical, and technological study of abduction. It presents new (...) ideas about inferential and information-processing foundations for knowledge and certainty. The authors argue that knowledge arises from experience by processes of abductive inference, in contrast to the view that it arises non-inferentially, or that deduction and inductive generalization are enough to account for knowledge. Much AI research is hypothetical, so the importance of this book is that it reports key discoveries about abduction that have been made as a result of designing, building, testing, and analyzing actual working knowledge-based systems for medical diagnosis and other abductive tasks. The book tells the story of six generations of increasingly sophisticated generic abduction machines, RED-1, RED-2, PEIRCE, MDX2, TIPS, QUAWDS, and the discovery of reasoning strategies that make it computationally feasible to form well-justified composite explanatory hypotheses, despite the threat of combinatorial explosion. The final chapter argues that perception is logically abductive and presents a layered-abduction computational model of perceptual information processing. This book will be of great interest to researchers in AI, cognitive science, and philosophy of science. (shrink)

This article explores pragmatism's associationwith relativism, not to rescue it fromrelativism but rather to highlight how aspectsof the classic pragmatists' positions supportqualified relativism. I do so in an effort tohelp restore ``relativism'' as a meaningfulconcept that is nuanced and complex, ratherthan naive and vulgar, as it is regularlyportrayed by more traditional philosophers. This nuanced relativism I call qualifiedrelativism. Qualified relativists insist thatall inquiry are affected by philosophicalassumptions which are culturally bound, andthat all inquirers are situated knowers who areculturally bound as (...) well. However, we cancompensate for our cultural embeddedness byopening our horizons and including others inour conversations. I connect the classicpragmatist points to current feministepistemological work and show that qualifiedrelativists (pragmatists, feminists, andpostmodernists) can claim roots to theirpositions in Peirce, James, and Dewey, some ofthe very scholars others turn to for theirpragmatic realism and their nonvulgar absolutism.

John Searle's Speech Acts made a highly original contribution to work in the philosophy of language. Expression and Meaning is a direct successor, concerned to develop and refine the account presented in Searle's earlier work, and to extend its application to other modes of discourse such as metaphor, fiction, reference, and indirect speech arts. Searle also presents a rational taxonomy of types of speech acts and explores the relation between the meanings of sentences and the contexts of their utterance. The (...) book points forward to a larger theme implicit in these problems - the basis certain features of speech have in the intentionality of mind, and even more generally, the relation of the philosophy of language to the philosophy of mind.

In this major new work, Bernstein explores the ethical and political dimensions of the modernity/post-modernity debate. Bernstein argues that modernity / post-modernity should be understood as a kind of mood - one which is amorphous, shifting and protean but which exerts a powerful influence on our current thinking. Focusing on thinkers such as Heidegger, Derrida, Foucault, Habermas and Rorty, Bernstein probes the strengths and weaknesses of their work, and shows how they have contributed to the formation of a new mood, (...) a new and distinctive constellation of ideas. This new constellation has put ethical and political issues back on the philosophical agenda, forcing us to confront anew, the Socratic question 'How should I live?'. (shrink)

Presenting a landmark in linguistics and cognitive science, Ray Jackendoff proposes a new holistic theory of the relation between the sounds, structure, and meaning of language and their relation to mind and brain. Foundations of Language exhibits the most fundamental new thinking in linguistics since Noam Chomsky's Aspects of the Theory of Syntax in 1965—yet is readable, stylish, and accessible to a wide readership. Along the way it provides new insights on the evolution of language, thought, and communication.

Already hailed as a masterpiece, Foundations of Language offers a brilliant overhaul of the last thirty-five years of research in generative linguistics and related fields. "Few books really deserve the cliché 'this should be read by every researcher in the field'," writes Steven Pinker, author of The Language Instinct, "but Ray Jackendoff's Foundations of Language does." Foundations of Language offers a radically new understanding of how language, the brain, and perception intermesh. The book renews the promise of early generative linguistics: (...) that language can be a valuable entrée into understanding the human mind and brain. The approach is remarkably interdisciplinary. Behind its innovations is Jackendoff's fundamental proposal that the creativity of language derives from multiple parallel generative systems linked by interface components. This shift in basic architecture makes possible a radical reconception of mental grammar and how it is learned. As a consequence, Jackendoff is able to reintegrate linguistics with philosophy of mind, cognitive and developmental psychology, evolutionary biology, neuroscience, and computational linguistics. Among the major topics treated are language processing, the relation of language to perception, the innateness of language, and the evolution of the language capacity, as well as more standard issues in linguistic theory such as the roles of syntax and the lexicon. In addition, Jackendoff offers a sophisticated theory of semantics that incorporates insights from philosophy of language, logic and formal semantics, lexical semantics of various stripes, cognitive grammar, psycholinguistic and neurolinguistic approaches, and the author's own conceptual semantics.

Die Wirkung der Schrift "Erkenntnis und Interesse" ging weit über die akademische Debatte hinaus und hatte auch unmittelbaren Einfluß auf den politischen Diskurs in den 70er Jahren. Denn die kritische Reflexion auf die vorgängig leitenden Interessen, die den Erkenntnisprozessen ihre Richtung geben, entzog der Kantischen Vorstellung den Boden, alle Erkenntnis beruhe allein auf der Selbstbestimmtheit des erkennenden Subjekts."Ich verspüre keine große Neigung, Gegenstand einer nostalgischen Veranstaltung zu sein." J.H.

Written in an outstandingly clear and lively style, this 1969 book provokes its readers to rethink issues they may have regarded as long since settled.
