In Concepts, Kinds, and Cognitive Development, Frank C. Keil provides a coherent account of how concepts and word meanings develop in children, adding to our understanding of the representational nature of concepts and word meanings at all ages. Keil argues that it is impossible to adequately understand the nature of conceptual representation without also considering the issue of learning. Weaving together issues in cognitive development, philosophy, and cognitive psychology, he reconciles numerous theories, backed by empirical evidence from nominal kinds studies, (...) natural-kinds studies, and studies of fundamental categorical distinctions. He shows that all this evidence, when put together, leads to a better understanding of semantic and conceptual development. The book opens with an analysis of the problems of modeling qualitative changes in conceptual development, investigating how concepts of natural kinds, nominal kinds, and artifacts evolve. The studies on nominal kinds document a powerful and unambiguous developmental pattern indicating a shift from a reliance on global tabulations of characteristic features to what appears to be a small set of defining ones. The studies on natural kinds document an analogous shift toward a core theory instead of simple definition. Both sets of studies are strongly supported by cross cultural data. While these patterns seem to suggest that the young child organizes concepts according to characteristic features, Keil argues that there is a framework of conceptual categories and causal beliefs that enables even very young children to understand kinds at a deeper, theoretically guided, level. This account suggests a new way of understanding qualitative change and carries strong implications for how concepts are represented at any point in development. A Bradford Book. (shrink)

Thomas S. Kuhn's classic book is now available with a new index.

Vagueness provides the first comprehensive examination of a topic of increasing importance in metaphysics and the philosophy of logic and language. Timothy Williamson traces the history of this philosophical problem from discussions of the heap paradox in classical Greece to modern formal approaches such as fuzzy logic. He illustrates the problems with views which have taken the position that standard logic and formal semantics do not apply to vague language, and defends the controversial realistic view that vagueness is a kind (...) of ignorance--that there really is a grain of sand whose removal turns a heap into a non-heap, but we cannot know which one it is.

The present paper argues that there is an affinity between Kuhn's "The Structure of Scientific Revolutions" and Wittgenstein's philosophy. It is maintained, in particular, that Kuhn's notion of paradigm draws on such Wittgensteinian concepts as language games, family resemblance, rules, forms of life. It is also claimed that Kuhn's incommensurability thesis is a sequel of the theory of meaning supplied by Wittgenstein's later philosophy. As such its assessment is not fallacious, since it is not an empirical hypothesis and it does (...) not have the relativistic implications Kuhn's critics repeatedly indicated. Although concepts are indeed relative to a language game or paradigm, interparadigmatic intelligibility is preserved through the standard techniques of translation or praxis. The impossibility of radical translation which is captured by the claim of incommensurability lies with that which cannot be said but only shown. (shrink)

This dissertation presents an objection to Wittgenstein's concept of family resemblances, three possible solutions to the objection, evaluations of the solutions, and a sketch of Wittgenstein's approach to the objection. My thesis is that none of the three proposed solutions is satisfactory, but that Wittgenstein can deal with the objection. ;Chapter I presents the Problem of the Under-Determination of Extension, the claim that family resemblances are not enough to explain the extension of a concept, since resemblances may be postulated between (...) cases falling under different concepts. ;Chapters II and III discuss three solutions proposed by commentators on family resemblances. The Basic Predicates Solution claims that points of family resemblance are sufficient conditions, and is incorrect since Wittgenstein denies that one can infer the applicability of a concept based on the presence of a resemblance to an instance of the concept. The Simple Properties Solution claims that only some concepts are family resemblance concepts, and depend upon concepts which are not family resemblance concepts, and is incorrect, since Wittgenstein does not require that family resemblance concepts be reducible to non-family resemblance concepts. The Bi-Directional Determination of Concepts Solution is the claim that a concept is determined by an interaction between facts about cases subsumed under it, and needs and purposes of language-users. This solution is non-Wittgensteinian by ignoring the ramifications of his concepts of grammar and language-games. ;Chapter IV argues that Wittgenstein deals with the original objection by developing new models for understanding language, involving the concepts of grammar and language-games.

Wittgenstein expounds his notion of a family resemblance in two important passages. The first is from The Blue Book:This craving for generality is the resultant of a number of tendencies connected with particular philosophical confusions. There is— The tendency to look for something common to entities which we commonly subsume under a general term. We are inclined to think that there must be something common to all games, say, and that this common property is the justification for applying the general (...) term “game” to the various games; whereas the games form a family the members of which have family likenesses …. There is a tendency rooted in our usual forms of expression, to think that a man who has learnt to understand a general term, say, the term “leaf,” has thereby come to possess a kind of general picture of a leaf, as opposed to pictures of particular leaves …. This again is connected with the idea that the meaning of a word is an image, or a thing correlated with the word. (shrink)

To correct the misconception that incommensurability implies incomparability, Kuhn lately develops a new interpretation of incommensurability. This includes a linguistic theory of scientific revolutions (the theory of kinds), a cognitive exploration of the language learning process (the analogy of bilingualism), and an epistemological discussion on the rationality of scientific development (the evolutionary epistemology). My focus in this paper is to review Kuhn's effort in eliminating relativism, highlighting both the insights and the difficulties of his new version of incommensurability . Finally (...) I suggest that some of Kuhn's difficulties can be overcome by adopting a concept of rationality that filly appreciates the important role of instruments in the development of science. (shrink)

Few philosophers of science have influenced as many readers as Thomas S. Kuhn. Yet no comprehensive study of his ideas has existed--until now. In this volume, Paul Hoyningen-Huene examines Kuhn's work over four decades, from the days before The Structure of Scientific Revolutions to the present, and puts Kuhn's philosophical development in a historical framework. Scholars from disciplines as diverse as political science and art history have offered widely differing interpretations of Kuhn's ideas, appropriating his notions of paradigm shifts and (...) revolutions to fit their own theories, however imperfectly. Hoyningen-Huene does not merely offer another interpretation--he brings Kuhn's work into focus with rigorous philosophical analysis. Through extended discussions with Kuhn and an encyclopedic reading of his work, Hoyningen-Huene looks at the problems and justifications of his claims and determines how his theories might be expanded. Most significantly, he discovers that The Structure of Scientific Revolutions can be understood only with reference to the historiographic foundation of Kuhn's philosophy. Discussing the concepts of paradigms, paradigm shifts, normal science, and scientific revolutions, Hoyningen-Huene traces their evolution to Kuhn's experience as a historian of contemporary science. From here, Hoyningen-Huene examines Kuhn's well-known thesis that scientists on opposite sides of a revolutionary divide "work in different worlds," explaining Kuhn's notion of a world-change during a scientific revolution. He even considers Kuhn's most controversial claims--his attack on the distinction between the contexts of discovery and justification and his notion of incommensurability--addressing both criticisms and defenses of these ideas. Destined to become the authoritative philosophical study of Kuhn's work, Reconstructing Scientific Revolutions both enriches our understanding of Kuhn and provides powerful interpretive tools for bridging Continental and Anglo-American philosophical traditions.

The author's concept of incommensurability is explicated by elaborating the claim that some terms essential to the formulation of older theories defy translation into the language of more recent ones. Defense of this claim rests on the distinction between interpreting a theory in a later language and translating the theory into it. The former is both possible and essential, the latter neither. The interpretation/translation distinction is then applied to Kitcher's critique of incommensurability and Quine's conception of a translation manual, both (...) of which take reference-preservation as the sole semantic criterion of translational adequacy. The paper concludes by enquiring about the additional criteria a successful translation must satisfy. (shrink)

A highly condensed account of the author's present view of some philosophical problems unresolved in The Structure of Scientific Revolutions. The concept of incommensurability, now considerably developed, remains at center stage, but the evolutionary metaphor, introduced in the final pages of the book, now also plays a principal role.
