Reasoning

The intelligence community relies on human-machine-based analytic strategies that 1) access and integrate vast amounts of information from disparate sources, 2) continuously process this information, so that, 3) a maximally comprehensive understanding of world actors and their behaviors can be developed and updated. Herein we describe an approach to utilizing outcomes-based learning (OBL) to support these efforts that is based on an ontology of the cognitive processes performed by intelligence analysts.

Um die Presse- und Meinungsfreiheit wird Tag für Tag gerungen - auch in Deutschland, wo sie im Grundgesetz verankert ist. Was darf man sagen? Wie weit geht die Meinungsfreiheit? Wo endet die Toleranz? Diese Fragen müssen immer wieder auf ein Neues beantwortet werden. Auch in der Demokratie wird die Meinungsfreiheit bedroht. Politscher Populismus und verrohte Kommunikation im Internet stellen das Grundrecht auf die Probe. Rechtsextremisten inszenieren sich als Opfer einer vermeintlichen Meinungsdiktatur, Hasskommentare zerstören die Streitkultur und provozieren neue Gesetze, die (...) im schlechtesten Fall ihrerseits die Meinungsfreiheit aushöhlen. Gut verständlich beschreiben Experten unterschiedlicher Disziplinen die Dimensionen und Herausforderungen der Meinungsfreiheit. Daraus ergibt sich eine facettenreiche Darstellung zu einem der großen Themen unserer Zeit. (shrink)

In this paper, I examine a kind of delusion in which the patients judge that their occurrent thoughts are false and try to abandon them precisely because they are false, but fail to do so. I call this delusion transparent, since it is transparent to the sufferer that their thought is false. In explaining this phenomenon, I defend a particular two-factor theory of delusion that takes the proper integration of relevant reasoning processes as vital for thought-evaluation. On this proposal, which (...) is a refinement of Gerrans’s account of delusion as unsupervised by decontextualized processing, I can have all my reasoning processes working reliably and thus judge that my delusion is false but, if I cannot use their outputs when revising the thought itself, the delusion will persist. I also sketch how this framework explains some interesting cases of failed belief-revision in the general population in which people judge that ~p but nonetheless continue to believe that p.

Enkratic reasoning – reasoning from believing that you ought to do something to an intention to do that thing – seems good. But there is a puzzle about how it could be. Good reasoning preserves correctness, other things equal. But enkratic reasoning does not preserve correctness. This is because what you ought to do depends on your epistemic position, but what it is correct to intend does not. In this paper, I motivate these claims and thus show that there is (...) a puzzle. I then argue that the best solution is to deny that correctness is always independent of your epistemic position. As I explain, a notable upshot is that a central epistemic norm directs us to believe, not simply what is true, but what we are in a position to know. (shrink)

In this paper, I will focus on a type of confabulation that emerges in relation to questions about mental attitudes whose causes we cannot introspectively access. I argue against two popular views that see confabulations as mainly offering a psychological story about ourselves. On these views, confabulations are the result of either a cause-tracking mechanism or a self-directed mindreading mechanism. In contrast, I propose the view that confabulations are mostly telling a normative story: they are arguments primarily offered to justify (...) one’s attitudes, and they are produced by our argumentative reasoning mechanism driven by the biological goal of presenting ourselves as good reasoners and as reliable sources of information.

John Broome has developed an account of rationality and reasoning which gives philosophical foundations for choice theory and the psychology of rational agents. We formalize his account into a model that differs from ordinary choice-theoretic models through focusing on psychology and the reasoning process. Within that model, we ask Broome’s central question of whether reasoning can make us more rational: whether it allows us to acquire transitive preferences, consistent beliefs, non-akratic intentions, and so on. We identify three structural types of (...) rationality requirements: consistency requirements, completeness requirements, and closedness requirements. Many standard rationality requirements fall under this typology. Based on three theorems, we argue that reasoning is successful in achieving closedness requirements, but not in achieving consistency or completeness requirements. We assess how far our negative results reveal gaps in Broome's theory, or deficiencies in choice theory and behavioral economics. (shrink)

Changing our minds isn't easy. Even when we recognize our views are disputed by intelligent and informed people, we rarely doubt our rightness. Why is this so? How can we become more open-minded, putting ourselves in a better position to tolerate conflict, advance collective inquiry, and learn from differing perspectives in a complex world? -/- Nathan Ballantyne defends the indispensable role of epistemology in tackling these issues. For early modern philosophers, the point of reflecting on inquiry was to understand how (...) our beliefs are often distorted by prejudice and self-interest, and to improve the foundations of human knowledge. Ballantyne seeks to recover and modernize this classical tradition by vigorously defending an interdisciplinary approach to epistemology, blending philosophical theorizing with insights from the social and cognitive sciences. -/- Many of us need tools to help us think more circumspectly about our controversial views. Ballantyne develops a method for distinguishing between our reasonable and unreasonable opinions, in light of evidence about bias, information overload, and rival experts. This method guides us to greater intellectual openness--in the spirit of skeptics from Socrates to Montaigne to Bertrand Russell--making us more inclined to admit that sometimes we don't have the right answers. With vibrant prose and fascinating examples from science and history, Ballantyne shows how epistemology can help us know our limits. (shrink)

In this paper we present an approach to conditional reasoning tasks based on two main ideas. The first idea is that, in contrast with what is usually assumed, an ‘if… then…’ sentence is not an adequate translation in natural language of a logical formula containing a material implication as its principal operator. The second idea is that when subjects are required to check the validity of a sentence in a task, their inferences are not driven uniquely by the content of (...) the sentence, but also by other information embedded in the task scenario and, eventually, by their knowledge about the topic (i.e. information stored in memory). Data from 30 subjects tested on six different tasks are reported as evidence for our approach. The results show that conditional tasks are significantly more complex only when they are presented with ‘if… then…’ sentences and when the subject cannot rely on any extra information, such as contextual information or knowledge about the topic.

La superación del racionalismo y del relativismo no ha podido gestarse con fecundidad. Posiblemente porque el absolutismo racionalista -que salva la razón a costa de anular la vida- y el relativismo -que salva la vida negando la razón- se han desplazado en una dimensión única que imposibilitaba la insumisión a ese dilema vertebrado por una concepción absolutista de la verdad y que nos constriñe a instalarnos en alguno de sus términos. La constante aparición del nexo entre los problemas antropológicos más (...) relevantes y la crítica de la metafísica exigen que la postmodernidad sea reubicada en un contexto que supere su inserción en un escenario que tengan por trasfondo únicamente a la modernidad. En otras palabras, hay una necesidad de trascender el binomio modernidad-postmodernidad. De esta manera, se considera que la tradición realista debe aparecer en escena en abierto diálogo crítico con los posicionamientos cronológicamente posteriores. Por lo que se refiere a la estructura de la presente obra hay que decir que sus once capítulos se distribuyen en tres partes. La primera de ellas intenta desentrañar y ordenar los elementos que generan el estado de cierta postración en el que se halla el pensamiento crítico-especulativo. En la segunda parte se procede a recorrer cada una de las derivaciones más relevantes de la desconfianza de la razón hacia sí misma. Por último, la tercera parte intenta poner de manifiesto qué posibilidades quedan al pensamiento de la constitución de lo nuevo tanto en el ámbito filosófico como en el pedagógico. Los modernos creyeron que al ser humano cabe forjarlo por el poder de la razón; los postmodernos estiman que no debe hacerse. ¿Es sólo por casualidad que hay una coincidencia fundamental entre ambas perspectivas? En el fondo, uno y otro convienen que la razón lo puede todo; modernos y postmodernos coinciden en la creencia del poder ilimitado de la razón y, como consecuencia de ello, creen en la posibilidad de la ilimitada y absoluta transformación de la totalidad de lo real. Y ello, aunque lo hagan en sentido diverso y lo valoren de manera inversa. Cabe, pues, pensar que, en el fondo, no hay más que una remodelación monótona de lo mismo. Las repercusiones del nihilismo, del relativismo moral, de la crisis antropológica postmoderna, de los nacionalismos identitarios, del pluralismo religioso, de la política democrática y de los tópicos del relativismo cultural son, pues, abordados –y enhebrados- en la Crítica de la razón moderna. Por ello, esta obra supone una seria y muy completa contribución al esclarecimiento de la vertebración del pensamiento y las prácticas culturales vigentes. Además, es una obra imprescindible en la biblioteca de profesores y de estudiantes de las facultades de Educación, Filosofía, Historia, Teología, Ciencias Políticas y Sociología. Y también resulta relevante para todas aquellas personas que se afanan por comprender los fundamentos teóricos de las perspectivas sociales y humanísticas actuales así como sus derivaciones y praxis concretas.

One of the important problems that have to be dealt with in the Philosophy of Science is to account for the high reliability of a very large part of our inductive inferences. This reliability is noteworthy because not only were many of these inferences made by ordinary people, even by children, but they were very often based on the observation of just a few positive instances. In the present paper, I deal with this problem by treating it as a normal (...) empirical problem. This approach enables us to make an important step towards an explanation of the phenomenon and, consequently, towards the formulation of a general theory of scientific inquiry. (shrink)

In this paper I argue that defeasible inferences are occasion-sensitive: the inferential connections of a given claim depend on features of the circumstances surrounding the occasion of inference. More specifically, it is an occasion-sensitive matter which possible defeaters have to be considered explicitly by the premises of an inference and which possible defeaters may remain unconsidered, without making the inference enthymematic. As a result, a largely unexplored form of occasion-sensitivity arises in inferentialist theories of content that appeal to defeasible inferences.

Lockheed Martin Corp. has funded research to generate a framework and methodology for developing semantic reasoning applications to support the discipline oflntelligence Analysis. This chapter outlines that framework, discusses how it may be used to advance the information sharing and integrated analytic needs of the Intelligence Community, and suggests a system I software architecture for such applications.

If the cultural variations concerning knowledge and research on ordinary reasoning are part of cultural history, what kind of historiographical method is needed in order to present the history of its evolution? This paper proposes to introduce the study of theories of reasoning into a historiographic perspective because we assume that the answer to the previous question does not only depend of internal controversies about how reasoning performance is explained by current theories of reasoning. [...].

This paper examines precursors and consequents of perceived relevance of a proposition A for a proposition C. In Experiment 1, we test Spohn's assumption that ∆P = P − P is a good predictor of ratings of perceived relevance and reason relations, and we examine whether it is a better predictor than the difference measure − P). In Experiment 2, we examine the effects of relevance on probabilistic coherence in Cruz, Baratgin, Oaksford, and Over's uncertain “and-to-if” inferences. The results suggest (...) that ∆P predicts perceived relevance and reason relations better than the difference measure and that participants are either less probabilistically coherent in “and-to-if” inferences than initially assumed or that they do not follow P = P. Results are discussed in light of recent results suggesting that the Equation may not hold under conditions of irrelevance or negative relevance. (shrink)

Laurence BonJour has proposed a novel defense of the inductive principle in response to a skeptical challenge posed by Hume. In this paper, I elaborate and criticize BonJour’s strategy. Along the way, I draw attention to Anthony Brueckner’s criticisms of BonJour’s approach, detailing why they fall short of providing an effective rebuttal of BonJour’s argument. By distinguishing and applying two different kinds of probability assessment to BonJour’s premises, I argue that BonJour’s a priori strategy fails to provide a cogent defense (...) of IP. I conclude by drawing out some implications for a priori attempts to argue for the principle. Laurence BonJour a proposé une façon novatrice de défendre son principe inductif en réponse à une proposition posée par Hume et pouvant être remise en question. Dans cet article, j’élabore et fais la critique de la stratégie de BonJour. Au cours de mon développement, j’attire l’attention sur les critiques formulées par Anthony Brueckner à l’égard de l’approche de BonJour, détaillant les raisons pour lesquelles elles ne parviennent pas à réfuter de manière cohérente l’argument de BonJour. En distinguant et en appliquant deux types distincts d’évaluation des probabilités aux hypothèses de BonJour, j’avance l’argument selon lequel la stratégie déductive de BonJour échoue à fournir une argumentation convaincante en faveur du PI. Je conclus en exposant les implications des tentatives visant à défendre le principe à partir d’arguments a priori. (shrink)

review of Laden's *Reasoning: a social picture* praising the aim and expressing puzzlement at the details,.

Without inductive reasoning, we couldn't generalize from one instance to another, derive scientific hypotheses, or predict that the sun will rise again tomorrow morning. Despite the widespread nature of inductive reasoning, books on this topic are rare. Indeed, this is the first book on the psychology of inductive reasoning in twenty years. The chapters survey recent advances in the study of inductive reasoning and address questions about how it develops, the role of knowledge in induction, how best to model people's (...) reasoning, and how induction relates to other forms of thinking. Written by experts in philosophy, developmental science, cognitive psychology, and computational modeling, the contributions here will be of interest to a general cognitive science audience as well as to those with a more specialized interest in the study of thinking.

Developing the Horizons of the Mind is a comprehensive book on Relational and Contextual Reasoning, a theory of the human mind which powerfully addresses key areas of human conflict such as the ideological conflict between nations, the conflict in close relationships and the conflict between science and religion. K. Helmut Reich provides a clear and accessible introduction to the fresh RCR way of thinking that encourages people to adopt an inclusive rather than an oppositional approach to conflict and problem-solving. Part (...) one outlines the key aspects of RCR theory and supporting empirical data and part two provides examples of its application in the world. RCR provides a stimulating and challenging tool to several disciplines, including philosophy, psychology, religious studies and education, and this book will be a valuable resource for cognitive scientists, psychotherapists, theologians, educators and all those involved in conflict resolution.

First published in 1976, this is a comprehensive study of practical thinking. Professor Körner shows the complex relations which a person's practical attitudes bear to each other, and shows in particular how their moral or prudential character depends not only on their content and form but also on their place in the system constituted by them. There are detailed accounts of the concepts of morality, prudence, justice, welfare and legality, as well as the logical foundations, epistemology and metaphysics of practical (...) thinking. The book is intended for philosophers and for those political theorists and social scientists who are concerned with the philosophical presuppositions and implications of their enquiries. The book is deliberately organized so that those with less interest in the logical issues dealt with in Part I can proceed quickly and easily to the more substantive issues in Parts II and III.

Two theories of propositional deductive reasoning are considered: the mental models of P. N. Johnson-Laird et al and the mental logic of M. D. Braine. The model theory is said to account for practically all of the known phenomena of deductive propositional reasoning, offer a general theory of conditionals, account for the most important aspects of Braine's theory, and predict new phenomena that rule theories cannot explain. It is argued that the model theory is flawed in a way that is (...) difficult to overcome, conditionals are seriously misrepresented, the algorithms proposed to implement it either allow invalid inferences or are psychologically useless, Braine's theory accounts for all of the new phenomena worth considering, and the model theory can predict Braine's results only at the cost of self-refutation. It is concluded that the mental model theory of propositional reasoning offers no reason to reject the program of mental logic. (shrink)

Inferences about spatial, temporal, and other relations are ubiquitous. This article presents a novel model-based theory of such reasoning. The theory depends on 5 principles. The structure of mental models is iconic as far as possible. The logical consequences of relations emerge from models constructed from the meanings of the relations and from knowledge. Individuals tend to construct only a single, typical model. They spontaneously develop their own strategies for relational reasoning. Regardless of strategy, the difficulty of an inference depends (...) on the process of integration of the information from separate premises, the number of entities that have to be integrated to form a model, and the depth of the relation. The article describes computer implementations of the theory and presents experimental results corroborating its main principle. (shrink)

The deductive validity of arguments from analogy is formally demonstrable. After a brief survey of the historical development of doctrines relevant to this claim the present article analyzes the “analogy of proper proportionality”, which meets two requirements of valid deduction. First, the referents of analogues by proportionality must belong to a common genus. Here it must be cautioned, however, that the common genus does not constitute the basis of the deductive inference. Rather, it is a prerequisite for the second and (...) decisive requirement, that the different logical content to which an analogous middle term corresponds must exhibit the same proportional relation to this common genus. In Section II I translate a natural language argument with such an analogous middle term into the language of classical first-order predicate calculus, and show that its conclusion follows from its premises with the force of deductive necessity. The rule of inference justifying the analogical entailment of the conclusion from the premises functions much like the familiar modus ponens rule, and could be called “modus ponens analogice”. The validity of this rule ought to be judged on the same basis as that of the traditional modus ponens rule – immediate logical intuition. The present article endeavors to facilitate this logical intuition by making the logical structure of inference by analogy formally explicit. (shrink)

Wie ist der Ort der Vernunft in einer natürlichen Welt zu bestimmen? Diese Frage hat wörtliche und metaphorische Lesarten. Im wörtlichen Sinne kann die Vernunft schwerlich einen Ort haben, wohingegen wir als vernunftfähige Wesen zugleich in der natürlichen Welt situiert sind. Man kann aber sinnvoll nach dem logischen Ort der Vernunft fragen, also danach, wie sich die Rede über Vernünftiges oder potentiell Vernünftiges zur Rede über Natürliches verhält. In der metaphorischen Lesart lautet die Frage, in welchem logischen oder begrifflichen Verhältnis (...) Redeweisen über Vernunft, Geist, Bedeutung, gute Gründe, Normen etc. zu den Diskursen der Naturwissenschaften stehen, die ja höchst erfolgreich ohne diese Begriffe auszukommen scheinen. Der Naturalismus behauptet ein Erklärungsprivileg naturwissenschaftlicher Methoden. Nach Sellars und Quine sind die Naturwissenschaften in kognitiver Hinsicht das Maß aller Dinge, nämlich der einzig verlässliche Weg, Wissen über die Welt zu erlangen. Will die Philosophie dem szientifischen Naturalismus eine vernünftige Alternative entgegensetzen, so ist sie herausgefordert, die Eigenart philosophischer Erkenntnissuche zu verteidigen, ohne die beispiellose Erfolgsgeschichte der Naturwissenschaften zu leugnen. Der Frage nach dem Verhältnis von Philosophie und Naturwissenschaft entspricht auf der Objektebene die nach dem Verhältnis von Vernunft und Natur. Vernunftfähige Wesen sind zwar mit all ihren Fähigkeiten Teil der Welt, doch es ist fraglich, ob und in welchem Sinne vernünftige Gründe, semantische Inhalte, Bewusstsein und Normen als Teil der Natur verstanden werden können. Will man den Begriff der Natur nicht jeglichen einschränkenden Gehaltes berauben, scheint er diese Zuordnung auszuschließen. Die an diesem Band beteiligten Autoren sind sich einig in dem Ziel, die Begriffe von 'Vernunft' und 'Natur' auf eine solche Weise zu entwickeln, dass die Frage nach der Ortsbestimmung eine sinnvolle Antwort ermöglicht, unabhängig davon, wie diese ausfällt.

We present a framework for verifying systems composed of heterogeneous reasoning agents, in which each agent may have differing knowledge and inferential capabilities, and where the resources each agent is prepared to commit to a goal (time, memory and communication bandwidth) are bounded. The framework allows us to investigate, for example, whether a goal can be achieved if a particular agent, perhaps possessing key information or inferential capabilities, is unable (or unwilling) to contribute more than a given portion of its (...) available computational resources or bandwidth to the problem. We present a novel temporal epistemic logic, BMCL-CTL , which allows us to describe a set of reasoning agents with bounds on time, memory and the number of messages they can exchange. The bounds on memory and communication are expressed as axioms in the logic. As an example, we show how to axiomatise a system of agents which reason using resolution and prove that the resulting logic is sound and complete. We then show how to encode a simple system of reasoning agents specified in BMCL-CTL in the description language of the Mocha model checker (Alur et al., Proceedings of the tenth international conference on computer-aided verification (CAV) , 1998), and verify that the agents can achieve a goal only if they are prepared to commit certain time, memory and communication resources.

This paper addresses the problem posed by the current split between the two opposed hypotheses in the growing literature on the fallacy of begging the question the epistemic hypothesis, based on knowledge and belief, and the dialectical one, based on formal dialogue systems. In the first section, the nature of split is explained, and it is shown how each hypothesis has developed. To get the beginning reader up to speed in the literature, a number of key problematic examples are analyzed (...) illustrating how both approaches can be applied. Useful tools are brought to bear on them, including the automated argument diagramming system Araucaria, and profiles of dialogue used to represent circular argumentation in a dialogue tableau format. These tools are used to both to model circular reasoning and to provide the contextual evidence needed to properly determine whether the circular reasoning in a given case is better judged fallacious or not. A number of technical problems that have impeded the development of both hypotheses are studied. One central problem is the distinction between argument and explanation. It is concluded that the best way to move forward and solve these problems is to reformulate the two hypotheses in such a way that they might be able to co-exist. On this basis, a unified methodology is proposed that allows each hypothesis to move forward as a legitimate avenue for research using the same tools. (shrink)

This paper concerns the apparent fact — discussed by Sinan Dogramaci and Brian Weatherson — that inductive reasoning often interacts in disastrous ways with patterns of reasoning that seem perfectly fine in the deductive case. In contrast to Dogramaci's and Weatherson's own suggestions, I argue that these cases show that we cannot reason inductively about arbitrary objects. Moreover, as I argue, this prohibition is neatly explained by a certain hypothesis about the rational basis of inductive reasoning — namely, the hypothesis (...) that inductive reasoning is fundamentally reasoning about what normally happens.

In _Reliable Reasoning_, Gilbert Harman and Sanjeev Kulkarni -- a philosopher and an engineer -- argue that philosophy and cognitive science can benefit from statistical learning theory, the theory that lies behind recent advances in machine learning. The philosophical problem of induction, for example, is in part about the reliability of inductive reasoning, where the reliability of a method is measured by its statistically expected percentage of errors -- a central topic in SLT. After discussing philosophical attempts to evade the (...) problem of induction, Harman and Kulkarni provide an admirably clear account of the basic framework of SLT and its implications for inductive reasoning. They explain the Vapnik-Chervonenkis dimension of a set of hypotheses and distinguish two kinds of inductive reasoning. The authors discuss various topics in machine learning, including nearest-neighbor methods, neural networks, and support vector machines. Finally, they describe transductive reasoning and suggest possible new models of human reasoning suggested by developments in SLT. (shrink)

Isaac Levi is one of the preeminent philosophers in the areas of pragmatic rationality and epistemology. This collection of essays constitutes an important presentation of his original and influential ideas about rational choice and belief. A wide range of topics is covered, including consequentialism and sequential choice, consensus, voluntarism of belief, and the tolerance of the opinions of others. The essays elaborate on the idea that principles of rationality are norms that regulate the coherence of our beliefs and values with (...) our rational choices. The norms impose minimal constraints on deliberation and inquiry, but they also impose demands well beyond the capacities of deliberating agents. This major collection will be eagerly sought out by a wide range of philosophers in epistemology, logic, and philosophy of science, as well as economists, decision theorists, and statisticians.

There has been a great deal of interaction among game theorists, philosophers and logicians in certain foundational problems concerning rationality, the formalization of knowledge and practical reasoning, and models of learning and deliberation. This volume brings together the work of some of the pre-eminent figures in their respective disciplines, all of whom are engaged in research at the forefront of their fields. Together they offer a conspectus of the interaction of game theory, logic and epistemology in the formal models of (...) knowledge, belief, deliberation and learning, and in the relationship between Bayesian decision theory and game theory, as well as between bounded rationality and computational complexity.

This is a major contribution to the theory of rational choice which will be of particular interest to philosophers and economists. The author sets out the foundations of rational choice, and then sketches a dynamic choice framework in which principles of ordering and independence follow from a number of apparently plausible conditions. However, there is potential conflict among these conditions, and when they are weakened to avoid it the usual foundations of rational choice no longer prevail. The thrust of the (...) argument is to suggest that the theory of rational choice is less deterministic than many suppose. (shrink)

What are our reasons for acting? Morality purports to give us these reasons, and so do norms of prudence and the laws of society. The theory of practical reason assesses the authority of these potentially competing claims, and for this reason philosophers with a wide range of interests have converged on the topic of reasons for action. This volume contains eleven essays on practical reason by leading and emerging philosophers. Topics include the differences between practical and theoretical rationality, practical conditionals (...) and the wide-scope ought, the explanation of action, the sources of reasons, and the relationship between morality and reasons for action. The volume will be essential reading for all philosophers interested in ethics and practical reason. (shrink)

In How We Get Along, philosopher David Velleman compares our social interactions to the interactions among improvisational actors on stage. He argues that we play ourselves - not artificially but authentically, by doing what would make sense coming from us as we really are. And, like improvisational actors, we deal with one another in dual capacities: both as characters within the social drama and as players contributing to the shared performance. In this conception of social intercourse, Velleman finds rational grounds (...) for morality, though not a rational guarantee. He maps a middle course between skepticism and rationalism, arguing that practical reasoning is 'pro-moral' without requiring moral action. The result is what he calls a 'Kinda Kantian metaethics'. How We Get Along is the summation of Velleman's thinking to date, incorporating and unifying previous work on agency, the self, the emotions, narrative and Kantian moral theory. (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.

Practical conflicts pervade human life. Agents have many different desires, goals, and commitments, all of which can come into conflict with each other. How can practical reasoning help to resolve these practical conflicts? In this collection of essays a distinguished roster of philosophers analyse the diverse forms of practical conflict. Their aim is to establish an understanding of the sources of these conflicts, to investigate the challenge they pose to an adequate conception of practical reasoning, and to assess the degree (...) to which that challenge can be met. These essays will serve as a major resource for students of philosophy but will also interest students and professionals in related fields of the social sciences such as psychology, political science, sociology and economics.
