Grennan bases his evaluation of arguments on two criteria: logical adequacy and pragmatic adequacy. He asserts that the common formal logic systems, while logically sound, are not very useful for evaluating everyday inferences, which are almost all deductively invalid as stated. Turning to informal logic, he points out that while more recent informal logic and critical thinking texts are superior in that their authors recognize the need to evaluate everyday arguments inductively, they typically cover only inductive fallacies, ignoring the inductively (...) sound patterns frequently used in successful persuasion. To redress these problems, Grennan introduces a variety of additional inductive patterns. Concluding that informal logic texts do not encourage precision in evaluating arguments, Grennan proposes a new argument evaluation procedure that expresses judgments of inferential strength in terms of probabilities. Based on theories of Stephen Toulmin, Roderick Chisholm, and John Pollock, his proposed system allows for a more precise judgment of the persuasive force of arguments. (shrink)

This article draws on Hannah Arendt’s analysis of authority in education, along with her insights into the workings of the imagination and the thinking process, to argue that participation in education should be conceived as an invitation to become towards the world. The potential of this invitation, the article argues, is located in the educator’s imaginative and thoughtful responsibility to receive the young as they are and as they are becoming on the one hand, and to represent the world to (...) them, on the other hand. The ways in which this potential can be negated are examined in relation to Arendt’s accounts of non-thinking and wilfulness. The article advances to the conclusion that participation in an education is possible only where young persons are received by educators who are persistently awake to their responsibility to receive the young people they educate anew.

The framework of plateaus, dips, and leaps shines light on periods when individuals may be inventing new methods of skilled performance. We begin with a review of the role performance plateaus have played in experimental psychology, human–computer interaction, and cognitive science. We then reanalyze two classic studies of individual performance to show plateaus and dips which resulted in performance leaps. For a third study, we show how the statistical methods of Changepoint Analysis plus a few simple heuristics may direct our (...) focus to periods of performance change for individuals. For the researcher, dips become the marker of exploration where performance suffers as new methods are invented and tested. Leaps mark the implementation of a successful new method and an incremental jump above the path plotted by smooth and steady log–log performance increments. The methods developed during these dips and leaps are the key to surpassing one's teachers and acquiring extreme expertise. (shrink)

The goal of this paper is two-fold. First, I begin by reviewing several of themajor points of emphasis among health educatorsas they begin to incorporate multiculturalissues into healthcare education. I thenconsider the role of moral relativism, which iscurrently being endorsed by some healtheducators, as the foundation for resolvingcross-cultural conflicts in healthcare. Iargue that moral relativism is ultimatelyinconsistent with the stated goals inmulticultural curricular proposals and fails toprovide an effective framework for consideringmoral conflicts in cross-cultural settings. Instead, I propose that those (...) methods seekingto establish a common morality, built uponmutually shared values, offer the mostpromising means of resolving cross-culturalconflicts. This leads to my second goal, tocompare recent work in moral pragmatism withwhat is now widely known in bioethics as moral``principlism.'' I argue that while proponentsof principlism and pragmatism each seek toestablish a common foundation for moraldeliberation, they fail to appreciatesignificant similarities between theirrespective approaches. Instead of offeringtwo completely unique and independent methodsof moral deliberation, I suggest thatprinciplism and pragmatism embrace commonthemes that point us in a positive direction,providing an effective framework useful forconsidering cross-cultural conflicts inhealthcare.

Identifying the missing or unstated premisses of arguments is important, because their logical quality depends on them. Textbook authors regard enthymematic syllogisms (e.g., "Elvis is a man, so Elvis is mortal") as having an unstated premiss - the major premiss (e.g., "All men are mortal"). They are said to be such because these syllogisms become formally valid when the major premiss is added (i.e., it is a gap-filler). I argue that unstated major premises are not gap-fillers: they support a part (...) of the argument that is already given implicitly - the inference claim ("If the premisses are true then the conclusion is true"). As such, their logical status is the same as that of an unstated proposition that supports the minor premiss, which is not part of the argument. Therefore, the so-called "major premiss" is not an unstated premiss of the enthymeme. (shrink)

Health professionals, by agreeing to provide care, accept a fiduciary role that entails an obligation to preserve trust. We trust health professionals to be competent, to promote patient interests, and to properly utilize their discretionary power. While some health professionals argue that such activities as secretly screening for drugs or sexually transmitted diseases are necessary to fulfill their fiduciary obligations, these may actually constitute a breach of trust. In this paper, I argue that, in the specific case of Munchausen’s Syndrome (...) by Proxy, covert surveillance is ethically justifiable and does not constitute a breach of trust and an abuse of the fiduciary relationship.

Constraints and dependencies among the elements of embodied cognition form patterns or microstrategies of interactive behavior. Hard constraints determine which microstrategies are possible. Soft constraints determine which of the possible microstrategies are most likely to be selected. When selection is non-deliberate or automatic the least effort microstrategy is chosen. In calculating the effort required to execute a microstrategy each of the three types of operations, memory retrieval, perception, and action, are given equal weight; that is, perceptual-motor activity does not have (...) a privileged status with respect to memory. Soft constraints can work contrary to the designer's intentions by making the access of perfect knowledge in-the-world more effortful than the access of imperfect knowledge in-the-head. These implications of soft constraints are tested in two experiments. In experiment 1 we varied the perceptual-motor effort of accessing knowledge in-the-world as well as the effort of retrieving items from memory. In experiment 2 we replicated one of the experiment 1 conditions to collect eye movement data. The results suggest that milliseconds matter. Soft constraints lead to a reliance on knowledge in-the-head even when the absolute difference in perceptual-motor versus memory retrieval effort is small, and even when relying on memory leads to a higher error rate and lower performance. We discuss the implications of soft constraints for routine interactive behavior, accounts of embodied cognition, and tool and interface design. (shrink)

Why games? How could anyone consider action games an experimental paradigm for Cognitive Science? In 1973, as one of three strategies he proposed for advancing Cognitive Science, Allen Newell exhorted us to “accept a single complex task and do all of it.” More specifically, he told us that rather than taking an “experimental psychology as usual approach,” we should “focus on a series of experimental and theoretical studies around a single complex task” so as to demonstrate that our theories of (...) human cognition were powerful enough to explain “a genuine slab of human behavior” with the studies fitting into a detailed theoretical picture. Action games represent the type of experimental paradigm that Newell was advocating and the current state of programming expertise and laboratory equipment, along with the emergence of Big Data and naturally occurring datasets, provide the technologies and data needed to realize his vision. Action games enable us to escape from our field's regrettable focus on novice performance to develop theories that account for the full range of expertise through a twin focus on expertise sampling and longitudinal studies of simple and complex tasks.

Several recent publications have suggested that hermeneutics, the method of literary criticism, might prove to be useful in medicine. In this essay I consider this thesis with particular attention to the claim that medicine is hermeneutics all the way down. After examining an anti-positivist critique of positivist medicine and arguing that hermeneutic interpretation involves a more radical critique of modern medicine, I examine the supposed consequences of hermeneutical universalism:relativism, skepticism andantirealism which further evaluation reveals to be only potential consequences of (...) hermeneutics. A brief discussion ofphronesis and of the possible texts of medicine concludes the article. (shrink)

Understanding the nature of errors in a simple, rule‐based task—programming a VCR—required analyzing the interactions among human cognition, the artifact, and the task. This analysis was guided by least‐effort principles and yielded a control structure that combined a rule hierarchy task‐to‐device with display‐based difference‐reduction. A model based on this analysis was used to trace action protocols collected from participants as they programmed a simulated VCR. Trials that ended without success (the show was not correctly programmed) were interrogated to yield insights (...) regarding problems in acquiring the control structure. For successful trials (the show was correctly programmed), steps that the model would make were categorized as matches to the model; steps that the model would not make were violations of the model. The model was able to trace the vast majority of correct keystrokes and yielded a business‐as‐usual account of the detection and correction of errors. Violations of the model fell into one of two fundamental categories. The model provided insights into certain subcategories of errors; whereas, regularities within other subcategories of error suggested limitations to the model. Although errors were rare when compared to the total number of correct actions, they were important. Errors were made on 4% of the keypresses that, if not detected, would have prevented two‐thirds of the shows from being successfully recorded. A misprogrammed show is a minor annoyance to the user. However, devices with the approximate complexity of a VCR are ubiquitous and have found their way into emergency rooms, airplane cockpits, power plants, and so on. Errors of ignorance may be reduced by training; however, errors in the routine performance of skilled users can only be reduced by design. (shrink)

Strategies for dealing with problems and making decisions in a moral way.

Le but de Pierre Hadot en développant la notion de philosophie ancienne comme « exercice spirituel » était de fournir une solution de rechange à la religion. Dans cette perspective, Hadot rend le triomphe de la chrétienté et de la scolastique médiévale, exemplifié par Thomas d’Aquin, responsable de la « perte de la philosophie comme manière de vivre ». Le jugement qu’il porte sur Thomas d’Aquin s’applique également au néoplatonisme ancien. Or, de fait, pour les deux il n’y a rien (...) d’abstrait dans la théorie de la philosophie comme ascension vers Dieu : la philosophie est une manière de vivre qui nous transforme et nous tourne vers le divin. Comme son prédécesseur néoplatonicien, l’Université médiévale considérait la philosophie comme un « exercice spirituel » dans le cadre d’une spiritualité chrétienne qui préparait aussi les intellectuels à une félicité surnaturelle.

For centuries debates about reason and its Other have animated and informed philosophy, art, science, and politics throughout Western civilization but nowhere, arguably, as deeply and turbulently as in Germany. This book explores the myriad issues surrounding these debates.

A scholarly edition of the writings of David Hume. The edition presents an authoritative text, together with an introduction, commentary notes, and scholarly apparatus.

This book attempts to give a comprehensive examination of the principal philosophical issues associated with the AIDS pandemic and in particular with the radical challenges that global diseases raise for modern society and political systems. The thesis of the book is that AIDS is but a part of a wider environmental and social crisis that not only challenges received opinion about the relationships between humantiy, technology and the environment, but challenges the ecological adaptability of modern social and political system. The (...) challenge posed by AIDS, and other diseases likely to appear in the next century, are explored in detail. (shrink)

This article describes some historical precursors that led to William James’s participation in the Hibbert Lectures and his subsequent publication of A Pluralistic Universe. William James viewed the monism–pluralism issue as the greatest issue the human mind can frame, and he returned to this issue again and again in his psychological and philosophical works. The Hibbert Lectures afforded an opportunity to explore the problem of monism and pluralism in a broadly religious or spiritual context. We describe James’s logical and experiential (...) attacks on monistic thinkers, his seemingly paradoxical introduction of Gustav Fechner’s panpsychism to English-speaking philosophers, and his spirited defense of pluralism. We conclude by discussing the relevance of James’s pluralism for current questions of unification in psychology. (shrink)

This book is written for individuals who want to learn about the philosophical foundations of political and economic freedom. It is an introduction and a guide to the principal theoretical ideas on liberty produced by the most influential and creative thinkers in history, with chapters on Adam Smith, Ludwig von Mises, and Carl Menger.

This paper contrasts the reception of Dionysius in relation to non-Christian philosophy during the Latin Middle Ages with his reception in twentieth-centuryChristian thought. The medievals, including Eriugena, Thomas Aquinas, Nicholas of Cusa, and many others, as a rule refuse to divide religion from philosophy and they distinguish or unite thinkers by their teaching rather than by their confessional adherence. Hence they see no need to set Dionysius in opposition to non-Christian philosophers such as Plato, Aristotle, and Proclus, or to repudiate (...) the latter in favor of the former. By contrast, Vladimir Lossky and Jean-Luc Marion, with their shared background in Etienne Gilson, celebrate Dionysius in opposition to the non-Christian Neoplatonists, whom they polemically misrepresent as reducing God to conceptual categories. These twentieth-century figures evince a sectarian religious narrowness that blinds them to the textual and philosophical community of Dionysius with his non-Christian sources. (shrink)

I outline features of the emerging consensus that philosophy has now liberated itself from the horizon of onto-theology with respect to the history of metaphysics. I draw on Jean-Marc Narbonne, Hénologie, Ontologie et Ereignis (Plotin-Proclus-Heidegger), conferences presented at La métaphysique: son histoire, sa critique, ses enjeux held at Laval University in 1998, and other recent work, showingwhy Heidegger’s horizon does not encompass ancient or medieval Platonic or Aristotelian philosophy. Noting that both French Neoplatonic studies after Bréhier and Heidegger in Identität (...) und Diff erenz were opposing Hegelian accounts of the history of philosophy, I suggest that: (1) both were reacting to the same problem, (2) French Neoplatonism was motivated by Heidegger’s questions, (3) Heidegger’s account of Being beyond the diff erence of Being and beings resembles the Neoplatonic account of the One.

Plato, and a wide variety of ancient, Arabic, and medieval Platonisms had a significant influence on Aquinas. The Corpus, with its quasi-Apostolic origin for Aquinas, was his most authoritative and influential source of Neoplatonism. His most influential early sources of Platonism came from Aristotle and Augustine, that is besides the Dionysian Corpus and the Liber. Aquinas greatly acknowledged the Neoplatonic, and the Peripatetic, commentaries and paraphrases he gradually acquired, because they enabled getting to the Hellenic sources. A great part of (...) Aquinas's last writing was devoted to explicating Aristotle's works including the Liber de causis, which was attributed to him. Aquinas wished to understand the philosophical schools such as their characters, the differences between and within them, their memberships, influences, histories, and the extent to which they are complementary. Aquinas gave an extended treatment of the history of philosophy, including lists of differences and agreements between Plato and Aristotle, beginning with ‘the opinions of the ancients and of Plato’ in his On Separate Substances. When Aquinas treated Aristotle in On Separate Substances, he did not leave his Neoplatonic framework behind. There is much more in On Separate Substances concerning the numbers, including an elaborate reasoning that saves the verbally opposed positions of both Proclus and Dionysius. (shrink)

Aquinas contradicts Isaiah VI. 6 because of his following of the ps. Dionysius, who is in turn reproducing the logical structures of Iamblichus and Proclus. These came to prevail despite doubts raised by earlier medieval theologians with the exception of Eriugena. Here are considered Thomas’ principles of biblical interpretation and the character of his Aristotelianism. His thought is shown to be a form of neoplatonic systematizing as developed by Iamblichus and Proclus.
