Presenting the most comprehensive and lucid account of the topic currently available, Robert Audi's "Practical Reasoning and Ethical Decision" is essential reading for anyone interested in the role of reason in ethics or the nature of human action. The first part of the book is a detailed critical overview of the influential theories of practical reasoning found in Aristotle, Hume and Kant, whilst the second part examines practical reasoning in the light of important topics in moral psychology - weakness of (...) will, self-deception, rationalization and others. In the third part, Audi describes the role of moral principles in practical reasoning and clarifies the way practical reasoning underlies ethical decisions. He formulates a comprehensive set of concrete ethical principles, explains how they apply to reasoning about what to do, and shows how practical reasoning guides moral conduct. (shrink)

The renowned philosopher John Searle reveals the fundamental nature of social reality. What kinds of things are money, property, governments, nations, marriages, cocktail parties, and football games? Searle explains the key role played by language in the creation, constitution, and maintenance of social reality. We make statements about social facts that are completely objective, for example: Barack Obama is President of the United States, the piece of paper in my hand is a twenty-dollar bill, I got married in London, etc. (...) And yet these facts only exist because we think they exist. How is it possible that we can have factual objective knowledge of a reality that is created by subjective opinions? This is part of a much larger question: How can we give an account of ourselves, with our peculiar human traits DS mind, reason, freedom, society - in a world that we know independently consists of mindless, meaningless particles? How can we account for our social and mental existence in a realm of brute physical facts? In answering this question, Searle avoids postulating different realms of being, a mental and a physical, or worse yet, a mental, a physical, and a social. There is just one reality: Searle shows how the human reality fits into that one reality. Mind, language, and civilization are natural products of the basic facts of the physical world described by physics, chemistry and biology. Searle explains how language creates and maintains the elaborate structures of human social institutions. These institutions serve to create and distribute power relations that are pervasive and often invisible. These power relations motivate human actions in a way that provides the glue that holds human civilization together. Searle shows how this account illuminates human rationality, free will, political power, and human rights. Our social world is a world created and maintained by language. (shrink)

This book provides a systematic analysis of many common argumentation schemes and a compendium of 96 schemes. The study of these schemes, or forms of argument that capture stereotypical patterns of human reasoning, is at the core of argumentation research. Surveying all aspects of argumentation schemes from the ground up, the book takes the reader from the elementary exposition in the first chapter to the latest state of the art in the research efforts to formalize and classify the schemes, outlined (...) in the last chapter. It provides a systematic and comprehensive account, with notation suitable for computational applications that increasingly make use of argumentation schemes. (shrink)

Fundamentals of Critical Argumentation presents the basic tools for the identification, analysis, and evaluation of common arguments for beginners. The book teaches by using examples of arguments in dialogues, both in the text itself and in the exercises. Examples of controversial legal, political, and ethical arguments are analyzed. Illustrating the most common kinds of arguments, the book also explains how to evaluate each kind by critical questioning. Douglas Walton shows how arguments can be reasonable under the right dialogue conditions by (...) using critical questions to evaluate them. The book teaches by example, both in the text itself and in exercises, but it is based on methods that have been developed through the author's thirty years of research in argumentation studies.

David Miller is the foremost exponent of the purist critical rationalist doctrine and here presents his mature views, discussing the role that logic and argument play in the growth of knowledge, criticizing the common understanding of argument as an instrument of justification, persuasion or discovery and instead advocating the critical rationalist view that only criticism matters. Miller patiently and thoroughly undoes the damage done by those writers who attack critical rationalism by invoking the sterile mythology of induction and justification that (...) it seeks to sweep away. In addition his new material on the debate on verisimilitude is essential reading for all working in this field. (shrink)

Media argumentation is a powerful force in our lives. From political speeches to television commercials to war propaganda, it can effectively mobilize political action, influence the public, and market products. This book presents a new and systematic way of thinking about the influence of mass media in our lives, showing the intersection of media sources with argumentation theory, informal logic, computational theory, and theories of persuasion. Using a variety of case studies that represent arguments that typically occur in the mass (...) media, Douglas Walton demonstrates how tools recently developed in argumentation theory can be usefully applied to the identification, analysis, and evaluation of media arguments. He draws upon the most recent developments in artificial intelligence, including dialogical theories of argument, which he developed, as well as speech act theory. Each chapter presents solutions to problems central to understanding, analyzing, and criticizing media argumentation. (shrink)

David Miller elegantly and provocatively reformulates critical rationalism—the revolutionary approach to epistemology advocated by Karl Popper—by answering its most important critics. He argues for an approach to rationality freed from the debilitating authoritarian dependence on reasons and justification. "Miller presents a particularly useful and stimulating account of critical rationalism. His work is both interesting and controversial... of interest to anyone with concerns in epistemology or the philosophy of science." —Canadian Philosophical Reviews.

This paper focuses on argumentation the institutional context of debate in the European Parliament. A parliamentary debate is a distinct argumentative activity type. In the pragma-dialectical approach, argumentative activity types are defined as conventionalized argumentative practices in which the possibilities for strategic maneuvering are predetermined. What are the characteristics of the activity type of a debate in European Parliament that predetermine the possibilities for strategic maneuvering?

The epistemologist John Pollock has implemented computationally an architecture for a rational agent which he calls OSCAR. OSCAR models both practical and theoretical (or epistemic) reasoning. I argue that Pollock's model of practical reasoning, which has seven components, is superior not only to the two-component belief-desire model stemming from Aristotle, but also to the three-component belief-desire-intention model developed especially by Michael Bratman. Despite its advantages, Pollock's model of practical reasoning is incomplete in at least three respects: it is solipsistic, it (...) is egoistic and it is unsocial. (shrink)

If the open society is a society that ‘sets free the critical powers of man’ (Popper, 1945, Introduction), then the subject of critical thinking, now widely taught in universities in North America and at the level of further education in the UK, might seem to be a welcome innovation. Caution is advised. By mistakenly supposing that thinking intelligently is identical with thinking logically, critical thinking textbooks almost invariably regard the purpose of argument to be a combination of justification and persuasion, (...) authoritarian goals that critical rationalists, and other supporters of the open society, must shun. If students do not learn the proper place of reason, and its limitations, they will be disappointed when it fails, and like many irrationalists in the past, may be induced to reason their way out of reason altogether.

This article aims to make a methodological contribution to the ‘argumentative turn’ in policy analysis and to the understanding of the public debate on the UK government’s austerity policies. It suggests that policy arguments are practical arguments from circumstances, goals and means-goal relations to practical conclusions (proposals) that can ground decision and action. Practical proposals are evaluated in light of their potential consequences. The article proposes a deliberation scheme and a set of critical questions for the evaluation of deliberation and (...) decision-making in conditions of incomplete knowledge (uncertainty and risk). It illustrates these questions by analyzing a corpus of articles from five newspapers over the two months following the adoption of the first austerity Budget in June 2010. It also suggests how ‘framing’ functions in deliberation and decision-making, and how analysis of ‘framing’ can be integrated with the analysis and evaluation of argumentation. (shrink)

The non-justificationist deductivism (or critical rationalism) of Karl Popper constitutes the only approach to human knowledge, including of course the natural and social sciences, that is capable of overcoming all the failings, and the plain contradictions, of the traditional doctrine of inductivism and of its modern incarnation, Bayesianism.
