Conceptual combination with prototype concepts

This paper deals with how people combine simple, prototype concepts into complex ones; e.g., how people combine the prototypes for brown and apple so they can determine the typicality of objects in the conjunction brown apple. We first consider a proposal from fuzzy-set theory (Zadeh, 1965), namely, that the typicality of an object in a conjunction is equal to the minimum of that object's typicality in the constituents (e.g., an object's typicality as a brown apple cannot exceed its typicality as a brown or as an apple). We evaluated this “min rule” against the typicality ratings of naive subjects in two experiments. For each of numerous pictured objects, one group of subjects rated its typicality with respect to an adjective concept, a second group rated its typicality vis-à-vis a noun concept, and a third group rated its typicality with respect to the adjective-noun conjunction. In both studies, most objects were rated as more typical of the conjunction than of the noun. These findings violate not only the min rule but also other simple rules for relating typicality in a conjunction to typicalities in the constituents. As an alternative to seeking such rules, we argue for an approach to conceptual combination that starts with the prototype representations themselves. We illustrate one version of this approach in some detail, and show how it accounts for the major findings of the present experiments.     

“All history is the history of thought”: competing British idealist historiographies

ABSTRACT

Along with utilitarianism, British idealism was the most important philosophical and practical movement in Britain and its Empire during the late-nineteenth and early-twentieth centuries. Even though the British idealists have regained some of their standing in the history of philosophy, their own historical theories still fail to receive the deserved scholarly attention. This article helps to fill that major gap in the literature. Understanding historiography as concerning the appropriate modes of enquiring into the recorded past, this article analyses the key historiographical commitments that underpin the writings of the early T.H. Green (section two), Edward Caird (section three), and F.H. Bradley (sections four and five). Section six explores the influence of Bradley's historiography. These approaches are linked by the belief that all thought can be properly understood only by critical historians who possess the appropriate tools with which to distinguish permanently valid truths from the transient imperfections with which those truths are mixed. A crucial division between them is the invocation of a neo-Hegelian Geist by the early Green and Caird, and Bradley's reliance on a progressive human nature. Moreover, the article establishes that R.G. Collingwood's highly influential theories of “absolute presuppositions” and “re-enactment” were taken largely from Bradley's historiography.     

The Cultural Turn: Empirical Studies and their Implications

This essay uses empirical studies to engage Richard Miller’s advocacy of a “cultural turn” in the study of religious ethics found in Friends and Other Strangers. The particular kind of empirical research I highlight here, cultural cognition, emphasizes the ways that belonging to a cultural group influences one’s reasoning when faced with controversial issues involving disputed facts. This approach underscores the significance of the cultural turn, but it also raises some important challenges for Miller’s accounts of moral psychology and public reason. I work to elucidate what those challenges are and point to some ways that taking cultural cognition seriously might open up fresh avenues for addressing perennial ethical issues.
