Among the many problems posed by Peirce's concept of abduction is how to determine the scope of this form of inference, and how to distinguish different types of abduction. This problem can be illustrated by taking a look at one of his best known definitions of the term:Abduction is the process of forming an explanatory hypothesis. It is the only logical operation which introduces any new idea; for induction does nothing but determine a value, and deduction merely evolves the necessary (...) consequences of a pure hypothesis.The second half of this quote is not part of the definition, but an explanation of it. However, it adds something to this definition because it says implicitly that there are only three logical.. (shrink)

A crucial problem of conflict management is that whatever happens in negotiations will be interpreted and framed by stakeholders based on their different belief-value systems and world views. This problem will be discussed in the first part of this article as the main cognitive problem of conflict management. The second part develops a general semiotic solution of this problem, based on Charles Peirce's concept of "diagrammatic reasoning." The basic idea is that by representing one 's thought in diagrams, the conditions (...) that determine interpretations can become visible, we can "experiment" with them, and we can change them eventually. The third part, finally, focuses on a concrete tool, called Logical Argument Mapping , that can be used in conflict management to perform such diagrammatic reasoning and to cope with the cognitive problems discussed in the first part. The Israeli-Palestinian conflict on the sovereignty over Jerusalem will be used as an example to show how LAM could work in practice. (shrink)

Wicked problems—that is, problems that can be framed in a number of different ways, depending on who is looking at them—pose ethical challenges for professionals that have scarcely been recognized as such. Even though wicked problems are all around us, they are rarely addressed in education. A reason for this failure might be that wicked problems pose almost insurmountable challenges in educational settings. This contribution shows how students can learn to cope with wicked problems in problem-based learning projects that are (...) structured by the Reflect! platform. (shrink)

Parties are back, and many are cheering. Party polarization has voters seeing stark differences between Democrats and Republicans and demonstrating more ideological constraint than previous generations. But these signs of a more “responsible” electorate are an illusion, because the public is no more knowledgeable than ever about the type of “information” it needs if it is to exercise effective control over the public‐policy outcomes it cares the most about. Indeed, polarization has produced a political environment where both voters and policy (...) makers may be less likely to learn about the potential consequences of their governing choices. The result is that holding elected politicians to account for policies treated as divisive ends in themselves has become easier—but that holding them accountable for policies intended as means to the achievement of consensual ends has become harder.

A large body of research in cognitive science differentiates human reasoning into two types: fast, intuitive, and emotional “System 1” thinking, and slower, more reflective “System 2” reasoning. According to this research, human reasoning is by default fast and intuitive, but that means that it is prone to error and biases that cloud our judgments and decision making. To improve the quality of reasoning, critical thinking education should develop strategies to slow it down and to become more reflective. The goal (...) of such education should be to enable and motivate students to identify weaknesses, gaps, biases, and limiting perspectives in their own reasoning and to correct them. This contribution discusses how this goal could be achieved with regard to reasoning that involves the construction of arguments; or more precisely: how computer-supported argument visualization tools could be designed that support reflection on the quality of arguments and their improvement. Three types of CSAV approaches are distinguished that focus on reflection and self-correcting reasoning. The first one is to trigger reflection by confronting the user with specific questions that direct attention to critical points. The second approach uses templates that, on the one hand, provide a particular structure to reason about an issue by means of arguments and, on the other, include prompts to enter specific items. And a third approach is realized in specifically designed user guidance that attempts to trigger reflection and self-correction. These types of approaches are currently realized only in very few CSAV tools. In order to inform the future development of what I call reflection tools, this article discusses the potential and limitations of these types and tools with regard to five explanations of the observation that students hardly ever engage in substantial revisions of what they wrote: a lack of strategies how to do it; cognitive overload; certain epistemic beliefs; myside bias; and over-confidence in the quality of one’s own reasoning. The question is: To what degree can each of the CSAV approaches and tools address these five potential obstacles to reflection and self-correction? (shrink)

We examine the ethical, social, and regulatory barriers that may hinder research on therapeutic potential of certain controversial controlled substances like marijuana, heroin, or ketamine. Hazards for individuals and society and potential adverse effects on communities may be good reasons for limiting access and justify careful monitoring of these substances. Overly strict regulations, fear of legal consequences, stigma associated with abuse and populations using illicit drugs, and lack of funding may, however, limit research on their considerable therapeutic potential. We review (...) the surprisingly sparse literature and address the particular ethical concerns pertinent to research with illicit and addictive substances, such as undue inducement, informed consent, therapeutic misconception, and risk to participants, researchers, and institutions. We consider the perspectives of key research stakeholders and explore whether they may be infected with bias. We conclude by proposing an empirical research agenda to provide an evidentiary basis for ethical reasoning. (shrink)

Can punishments ever meaningfully be proportioned in severity to the seriousness of the crimes for which they are imposed? A great deal of attention has been paid to the general justification of punishment, but the thorny practical questions have received significantly less. Serious analysis has seldom delved into what makes crimes more or less serious, what makes punishments more or less severe, and how links are to be made between them. In Of One-eyed and Toothless Miscreants, Michael Tonry has (...) gathered together a distinguished cast of contributors to offer among the first sustained efforts to specify with precision how proportionality can be understood in relation to the implementation of punishment. Each chapter examines scholarly and lay thinking about punishment of people convicted of crimes with particular emphasis on "making the punishment fit the crime." The contributors challenge the most prevalent current theories and emphasize the need for a shift away from the politicized emotionalism of recent decades. They argue that theories that coincided with mass incarceration and rampant injustice to countless individuals are evolving in ways that better countenance moving toward more humane and thoughtful approaches.0Written by many of the leading thinkers on punishment, this volume dissects previously undeveloped issues related to considerations of deserved punishment and provides new ways to understand both the severities of punishment and the seriousness of crime.

_Taking Religious Claims Seriously_ is a systematic, critical, and comprehensive study of the fundamental questions of the philosophy of religion: religious experience, the existence and nature of God, religious knowledge and truth, good and evil, immortality of the soul, religious diversity, religious claims about the person, faith, and the religious way of life. In this study the author seeks to capture the reality and meaning of the religious as such: What is the foundation of religion? Under what conditions is an (...) authentic religious way of life possible? His method of inquiry is phenomenological. The author begins his discussion with a general characterization of the basic features of all the literate and illiterate religions of the world. He then identifies the ideas, beliefs, and concerns which are common to these religions: What are the central claims of these religions? How did the various religions understand these claims? The author makes a serious attempt to clarify these claims and explore the possibility for a reconcilation between them. For him, the foundation of religion is the religious experience, and the essence of this experience consists in a serious, cognitive, and meaningful encounter with the Ultimate Being. This being is the ground of the world and human life. This book is a comparative, pluralistic study of the philosophy of religion. (shrink)

This volume provides a critical survey of the major figures and ideas of 20th century political philosophy.

Founded in 1365, not long after the Great Plague ravaged Europe, the University of Vienna was revitalized in 1384 by prominent theologians displaced from Paris--among them Henry of Langenstein. Beginning with the 1384 revival, Michael Shank explores the history of the university and its ties with European intellectual life and the city of Vienna. In so doing he links the abstract discussions of university theologians with the burning of John Hus and Jerome of Prague at the Council of Constance (...) (1415-16) and the destruction of the Jewish community of Lower Austria (1421). Like most other scholars of the period, Henry of Langenstein (d. 1397) at one time believed that Aristotle's syllogistic was universally valid even in Trinitarian theology. In touch with the vibrant Jewish community in Vienna, Langenstein had high hopes of converting its members by logical argument. When he failed in his purpose, he lost his confidence in Aristotle's syllogistic as a universal tool of apologetics and handmaiden to Trinitarian theology. ("Unless you believe, you shall not understand," he quoted from Isaiah, in order to express his change of opinion.) During the next generation, the intellectual climate at the university changed from academic openness to increasing rigidity, and theologians turned from argument to persecution.

Based on a typology of five basic forms of abduction, I propose a new definition of abductive insight that empha sizes in particular the inferential structure of a belief system that is able to explain a phenomenon after a new, abductive ly created component has been added to this system or the entire system has been abductively restructured. My thesis is, first, that the argumentative structure of the pursued problem solution guides abductive creativity and, second, that diagrammatic reasoning—if conceptualized according (...) to the requirements defined by Charles Peirce—can support this guidance. This support is mainly possible based on the normative power of the system of representation that has to be used to construct diagrams and to perform experiments with them. (shrink)

Mirrored-self misidentification is the delusional belief that one's own reflection in the mirror is a stranger. In two experiments, we tested the ability of hypnotic suggestion to model this condition. In Experiment 1, we compared two suggestions based on either the delusion's surface features (seeing a stranger in the mirror) or underlying processes (impaired face processing). Fifty-two high hypnotisable participants received one of these suggestions either with hypnosis or without in a wake control. In Experiment 2, we examined the extent (...) to which social cues and role-playing could account for participants' behaviour by comparing the responses of 14 hypnotised participants to the suggestion for impaired face processing (reals) with those of 14 nonhypnotised participants instructed to fake their responses (simulators). Overall, results from both experiments confirm that we can use hypnotic suggestion to produce a compelling analogue of mirrored-self misidentification that cannot simply be attributed to social cues or role-playing.

A central challenge for research on how we should prepare students to manage crossing boundaries between different knowledge settings in life long learning processes is to identify those forms of knowledge that are particularly relevant here. In this paper, we develop by philosophical means the concept of a dialectical system as a general framework to describe the de-velopment of knowledge networks that mark the starting point for learning processes, and we use semiotics to discuss the epistemological thesis that any cognitive (...) access to our world of objects is mediated by signs and diagrammatic reasoning and abduction as those forms of practical knowledge that are crucial for the development of knowledge networks. The rich-ness of this theoretical approach becomes evident by applying it to an example of learning in a biological research context. At the same time, we take a new look at the role of mathematical knowledge in this process. (shrink)

Some philosophers and theologians have argued that God-centeredness cannot be a condition of inter-religious dialogue for at least four reasons. First, it is an existential fact that all religions tend to view the truth of their beliefs and values as absolute. Second, all religions are embedded in radically different cultural contexts; this kind of difference undercuts the possibility of inter-religious dialogue. Third, grounding all the religions in a transcendent reality relativizes their beliefs and values. Moreover, people worship “their” God, not (...) a neutral reality. Fourth, it is difficult to ground all the religions in a transcendent, neutral realty. This paper critically evaluates these arguments and defends the proposition that the mystical experience provides a justifiable basis for the claim that the transcendent is not only a wealth of being but also an infinite wealth of being and that the same transcendent is “revealed” in the mystical experience which underlies all the major religions. The transcendent is the common ground on which all the religions stand in inter-religious dialogue qua religions. (shrink)

This argument map presents Paul Loewi’s crucial experiment in which he showed that neural transmissions of signals are chemical in nature, not electrical, in form of an argumentation. The map can be used in science education to show how the formulation of hypotheses should be related to a corresponding determination of experimental designs.

In both Marx and Schaff, Marxism does not provide an adequate interpretation of the individual. The main reason for this is that there is no satisfactory analysis of autonomy.

Why do we formulate arguments? Usually, things such as persuading opponents, finding consensus, and justifying knowledge are listed as functions of arguments. But arguments can also be used to stimulate reflection on one’s own reasoning. Since this cognitive function of arguments should be important to improve the quality of people’s arguments and reasoning, for learning processes, for coping with “wicked problems,” and for the resolution of conflicts, it deserves to be studied in its own right. This contribution develops first steps (...) towards a theory of reflective argumentation. It provides a definition of reflective argumentation, justifies its importance, delineates it from other cognitive functions of argumentation in a new classification of argument functions, and it discusses how reflection on one’s own reasoning can be stimulated by arguments.
