This paper uses examples of conversational understandings, misunderstandings and non-understandings to explore the role of prototypes and schemata in conversational understanding. An investigation of the procedures by which we make sense of lexical items in utterances by fitting prototypes into schemata is followed by an examination of how schemata are instantiated across conversational sequences by means of topics. In interaction, conflicts over meaning illuminate the decisive role of social and cultural factors in understanding. Overall, understanding is seen to be critically (...) dependent on principles of categorisation and contrast, which form the basis of both cognitive and sociocultural means of organisation. (shrink)

The study of argument has never before been so wide-ranging. The evidence for this claim is to be found in a growing number of different conceptions of argument, each of which purports to describe some component of argument that is effectively over-looked by other conceptions of this notion. Just this same sense that a vital component of argument is being overlooked by current conceptions of this notion is what motivates Dale Hample to pursue a specifically cognitive conception of argument. However, (...) Hamples contribution to the study of argument extends beyond his development of a view of argument as cognition. For Hample is reflective on the interrelationship of his cognitive conception of argument to two other views of argument within which most conceptions of this notion may be taken to fall, the traditional view of argument as a textual product and the view of argument as a social phenomenon. I will argue, however, that what starts out as a well-intentioned aim on the part of Hample to pursue a comprehensive analysis of the notion of argument ends in the circumscription of this concept through Hample s denial of the primacy of argument. I will also argue that a circumscribed concept of argument is an unintelligible concept of argument. The context of my claims will be a similar charge of unintelligibility by Hilary Putnam against a logical positivistic conception of rationality. (shrink)

Some current attempts to go beyond the narrow scope of rational choice theory (RCT) in the social sciences and the artificial reconstructions it sometimes provides focus on the arguments that people give to justify their beliefs and behaviors themselves. But the available argumentation theories are not constructed to fill this gap. This article argues that relevance theory, on the contrary, suggests interesting tracks. This provocative idea requires a rereading of Sperber and Wilson's theory. Actually, the authors do not explicitly support (...) RCT, and Sperber has even strongly criticized methodological individualism, which most of the time underlies RCT, in favor of infra-individualism. A key point of the argument presented here is to show that Sperber and Wilson do not firmly distinguish between infra-individualism and subintentionality. Only subintentionality is needed. Key Words: argumentation • rational choice • relevance theory • methodological individualism. (shrink)

Systems based on symbolic knowledge have performed extremely well in processing reason, yet, remain beset with problems of brittleness in many domains. Connectionist approaches do similarly well in emulating interactive domains, however, have struggled when modelling higher brain functions. Neither of these dichotomous approaches, however, have provided many inroads into the area of human reasoning that psychology and sociology refer to as the process of practice. This paper argues that the absence of a model for the process of practise in (...) current approaches is a significant contributor to brittleness. This paper will investigate how the process of practise relates to deeper forms of contextual representations of knowledge. While researchers and developers of knowledge based systems have often incorporated the notion of context they treat context as a static entity, neglecting many connectionists’ work in learning hidden and dynamic contexts. This paper argues that the omission of these higher forms of context is one of the fundamental problems in the application and interpretation of symbolic knowledge. Finally, these ideas for modelling context will lead to the reinterpretation of situation cognition which makes a significant step towards a philosophy of knowledge that could lead to the modelling of the process of practice.
