Many children and adults experience significant breakdown in the use of language. The resulting pragmatic disorders present a considerable barrier to effective communication. This book is the first critical examination of the current state of our knowledge of pragmatic disorders and provides a comprehensive overview of the main concepts and theories in pragmatics. It examines the full range of pragmatic disorders that occur in children and adults and discusses how they are assessed and treated by clinicians. Louise Cummings attempts to integrate the fields of pragmatics, language pathology and cognitive science by examining the ways in which pragmatics can make a useful contribution to debates about cognitive theories of autism. The reader is encouraged to think in a critical fashion about how clinicians, experimentalists and theorists deal with pragmatic issues.

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

Few, if any, scientific inquiries are conducted against a background of complete knowledge, a background in which inquirers are in possession of the ‘full facts’ that relate to a particular question or issue. More often than not, scientists are compelled to conduct their deliberations in contexts of epistemic uncertainty, in which partial knowledge or even a total absence of knowledge characterise inquiry. Nowhere is this epistemic uncertainty more evident, or indeed more successfully controlled, than in the branch of scientific inquiry called epidemiology. In this paper, I examine how epidemiologists overcome the unique challenges to inquiry that are posed by epistemic uncertainty. In specific terms, I contend that epidemiologists employ analogical reasoning strategies in an attempt to advance their inquiries in situations that are epistemically uncertain. The context for my claims will be the early inquiries that were conducted into the emergence of HIV/AIDS in the United States. I argue that early scientific work in relation to HIV/AIDS was directly premised upon epidemiological investigations in which analogical reasoning with hepatitis B had featured significantly. I conclude that epidemiological investigations of AIDS exemplify the capacity of analogical reasoning to advance inquiry under conditions of epistemic uncertainty. To this extent, analogical reasoning should be a concern both to those who address practical problems of uncertainty management and to those who pursue theoretical debates within argumentation studies and epistemology.

The study of the fallacies has changed almost beyond recognition since Charles Hamblin called for a radical reappraisal of this area of logical inquiry in his 1970 book Fallacies. The “witless examples of his forbears” to which Hamblin referred have largely been replaced by more authentic cases of the fallacies in actual use. It is now not unusual for fallacy and argumentation theorists to draw on actual sources for examples of how the fallacies are used in our everyday reasoning. However, an aspect of this move towards greater authenticity in the study of the fallacies, an aspect which has been almost universally neglected, is the attempt to subject the fallacies to empirical testing of the type which is more commonly associated with psychological experiments on reasoning. This paper addresses this omission in research on the fallacies by examining how subjects use two fallacies – circular argument and analogical argument – during a reasoning task in which subjects are required to consider a number of public health scenarios. Results are discussed in relation to a view of the fallacies as cognitive heuristics that facilitate reasoning in a context of uncertainty.
