Plato's reflections on Forms have generally been overlooked, in contemporary Philosophy of Language, as a serious resource for illuminating the notion of word meaning. In part, this is due to the influence of Wittgenstein's critical reflections on looking for ‘something in common’ as explanatory for use of a general term. I argue that, far from being undermined, appeal to Forms can both help explain, and provide corrective critical insight into, Wittgenstein's observations. Plato's reflections provide insight into word meaning that is (...) relevant for contemporary research. Relevant considerations include an explanation as to why an item is F; looking to ‘what something is’; the compresence of opposites; whether participation in a Form involves approximation to the Form.

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.

It is a commonly raised argument against the family resemblance account of concepts that there is no limit to a concept's extension. An account of family resemblance which attempts to provide a solution to this problem by including both similarity among instances and dissimilarity to non-instances has been developed by the philosopher of science Thomas Kuhn. Similar solutions have been hinted at in the literature on family resemblance concepts, but the solution has never received a detailed investigation. I shall provide (...) a reconstruction of Kuhn's theory and argue that his solution necessitates a developmental perspective wchich builds on both the transmission of taxonomies between generations and a progressive development through history.

I develop in this paper a conception of artefacts based on L. Wittgenstein’s idea of family resemblance. My approach peruses the notion of frame, which was invented in cognitive psychology as an operationisable extension of this philosophical idea. Following the metaphor of life-cycle I show how this schematic notion of frame may be filled with the content relevant for artefacts if we consider them from the point of view of their histories. The resulting conception of artefacts provides a new insight (...) into the current debate on artefact categorisation. (shrink)

Peter Geach proposed a substitutional construal of quantification over thirty years ago. It is not standardly substitutional since it is not tied to those substitution instances currently available to us; rather, it is pegged to possible substitution instances. We argue that (i) quantification over the real numbers can be construed substitutionally following Geach's idea; (ii) a price to be paid, if it is that, is intuitionism; (iii) quantification, thus conceived, does not in itself relieve us of ontological commitment to real (...) numbers.

I argue for a novel answer to the question “What is hope?”. On my view, rather than aiming for a compound account, i.e. analysing hope in terms of desire and belief, we should understand hope as an irreducible concept. After criticizing influential compound accounts of hope, I discuss Segal and Textor's alternative of describing hope as a primitive mental state. While Segal and Textor argue that available developments of the standard definition do not offer sufficient conditions for hope, I question (...) the deep‐seated idea that desire and belief are even necessary conditions for hope. My suggestion is that we should take seriously the fact that we hope in a great variety of ways and should question the search for elements that are common to all cases. A promising alternative follows the Wittgensteinian idea that cases of hope are related in terms of family resemblance, i.e. are multiply realizable on the ontological level while falling under the non‐definable concept of hope.
