Various social animal species have been noted to inhibit aggressive attacks when a conspecific displays submission cues. Blair (1993) has suggested that humans possess a functionally similar mechanism which mediates the suppression of aggression in the context of distress cues. He has suggested that this mechanism is a prerequisite for the development of the moral/conventional distinction; the consistently observed distinction in subject's judgments between moral and conventional transgressions. Psychopaths may lack this violence inhibitor. A causal model is developed showing how (...) the lack of this mechanism would explain the core behavioural symptoms associated with the psychopathic disorder. A prediction of such a causal model would be that psychopaths should fail to make the moral/conventional distinction. This prediction was confirmed. The implication of this finding for other theories of morality is discussed. (shrink)

Psychopaths continue to be demonised by the media and estimates suggest that a disturbing percentage of the population has psychopathic tendencies. This timely and controversial new book summarises what we already know about psychopathy and antisocial behavior and puts forward a new case for its cause - with far-reaching implications. Presents the scientific facts of psychopathy and antisocial behavior. Addresses key questions, such as: What is psychopathy? Are there psychopaths amongst us? What is wrong with psychopaths? Is psychopathy due to (...) nature or nurture? And can we treat psychopaths? Reveals the authors' ground-breaking research into whether an underlying abnormality in brain development leaves psychopaths with an inability to feel emotion or fear. The resulting theory could lead to early diagnosis and revolutionize the way society, the media and the state both views and contends with the psychopaths in our midst. (shrink)

Empathy is a lay term that is becoming increasingly viewed as a unitary function within the field of cognitive neuroscience. In this paper, a selective review of the empathy literature is provided. It is argued from this literature that empathy is not a unitary system but rather a loose collection of partially dissociable neurocognitive systems. In particular, three main divisions can be made: cognitive empathy , motor empathy, and emotional empathy. The two main psychiatric disorders associated with empathic dysfunction are (...) considered: autism and psychopathy. It is argued that individuals with autism show difficulties with cognitive and motor empathy but less clear difficulties with respect to emotional empathy. In contrast, individuals with psychopathy show clear difficulties with a specific form of emotional empathy but no indications of impairment with cognitive and motor empathy. (shrink)

Using measures developed by Singhapakdi et al. (1996, Journal of Business ethics 15, 1131–1140) the perceived importance of ethics and social responsibility (PRESOR) is measured among MBA students in the United States, Malaysia and Ukraine revealing a stockholder view and two stakeholder views. Relativism and Idealism are also measured. The scores of MBA students are compared among each other and with those of the U.S. managers who were part of the original study. Managers'' scores tend to be significantly higher on (...) the Stockholder and Stakeholder II views, and much lower on Relativism than the MBA students. The Malaysian MBA students scored higher than did the American MBA students on Relativism, Idealism and the Stockholder view. The Ukrainian MBA students'' scores on the three PRESOR factors are generally similar to those of the American MBAs, while they had the highest scores of any group on the Relativism scale. Overall, the patterns of responses, as much as the significant differences on specific scales, support the notion that culture, however defined, affects both values and ethics. Several directions for future research are identified.''. (shrink)

The paper's thesis is that dialogue is not an adequate model for all types of argument. The position of Walton is taken as the contrary view. The paper provides a set of descriptions of dialogues in which arguments feature in the order of the increasing complexity of the argument presentation at each turn of the dialogue, and argues that when arguments of great complexity are traded, the exchanges between arguers are turns of a dialogue only in an extended or metaphorical (...) sense. It argues that many of the properties of engaged back-and-forth exchanges of paradigmatic argument dialogues are not found in ‘solo’ arguments, and that at least some of the norms appropriate to the former type of argument, such as some of the pragma-dialectical rules of van Eemeren and Grootendorst's model, do not apply to the latter.

Do not define argument by its use to persuade. for other uses of arguments exist. An argument is a proposition and a reason for it. and argumentation is an interchange involving two or more parties resulting in the assertion of one or more arguments coupled with anticipated or actual critical responses. A logically good argument has grounds adeq uate for the purposes at hand (true, probable, plausible, acceptable to the audience) and the grounds provide adequate support for the conclusion. The (...) norms for good logic in arguments are different from the norms for the good use of arguments. (shrink)

The question, “What norms are appropriate for the evaluation of the probative merits of visual arguments?” underlies the investigation of this paper. The notions of argument and of multimodal visual argument employed in the study are explained. Then four multimodal visual arguments are analyzed and their probative merits assessed. It turns out to be possible to judge these qualities using the same criteria that apply to verbally expressed arguments. Since the sample is small and not claimed to be representative, this (...) finding can at best be regarded as suggestive for the probative assessment of multimodal visual arguments in general.

This article challenges the view that rhetoric, dialectic and logic are three perspectives on argument, relating respectively to its process, its procedure, and its product. It also questions the view that rhetorical arguments represent a distinctive type. It suggests that, as related to argument, rhetoric is the theory of arguments in speeches, dialectics the theory of arguments in conversations, and logic the theory of good reasoning in each.

In this overview article, we first explain what we take informal logic to be, discussing misconceptions and distinguishing our conception of it from competing ones; second, we briefly catalogue recent informal logic research, under 14 headings; third, we suggest four broad areas of problems and questions for future research; fourth, we describe current scholarly resources for informal logic; fifth, we discuss three implications of informal logic for philosophy in particular, and take note ofpractical consequences of a more general sort.

This study investigated the performance of boys with psychopathic tendencies and comparison boys, aged 9 to 17 years, on two tasks believed to be sensitive to amygdala and orbitofrontal cortex func- tioning. Fifty-one boys were divided into two groups according to the Psychopathy Screening Device (PSD, P. J. Frick & R. D. Hare, in press) and presented with two tasks. The tasks were the gambling task (A. Bechara, A. R. Damasio, H. Damasio, & S. W. Anderson, 1994) and the Intradimensional/ (...) Extradimensional (ID/ED) shift task (R. Dias, T. W. Robbins, & A. C. Roberts, 1996). The boys with psychopathic tendencies showed impaired performance on the gambling task. However, there were no group differences on the ID/ED task either for response reversal or extradimensional set shifting. The implications of these results for models of psychopathy are discussed.

J. Anthony Blair is a prominent international figure in argumentation studies. He is among the originators of informal logic, an author of textbooks on the informal logic approach to argument analysis and evaluation and on critical thinking, and a founder and editor of the journal Informal Logic. Blair is widely recognized among the leaders in the field for contributing formative ideas to the argumentation literature of the last few decades. This selection of key works provides insights into the history of (...) the field of argumentation theory and various related disciplines. It illuminates the central debates and presents core ideas in four main areas: Critical Thinking, Informal Logic, Argument Theory and Logic, Dialectic and Rhetoric. (shrink)

In this paper, we will consider the neuro-cognitive systems involved in mediating morality. Five main claims will be made. First, that there are multiple, partially separable neuro-cognitive architectures that mediate specific aspects of morality: social convention, care-based morality, disgust-based morality and fairness/justice. Second, that all aspects of morality, including social convention, involve affect. Third, that the neural system particularly important for social convention, given its role in mediating anger and responding to angry expressions, is ventrolateral prefrontal cortex. Fourth, that the (...) neural systems particularly important for care-based morality are the amygdala and medial orbital frontal cortex. Fifth, that while Theory of Mind is not a prerequisite for the development of affect-based 'automatic moral attitudes', it is critically involved in many aspects of moral reasoning. (shrink)

The history of note?taking has only begun to be written. On the one hand, the basic functions of selecting, summarizing, storing and sorting information garnered from reading, listening, observing and thinking can be identified in most literate contexts in some form or other. On the other hand, Renaissance humanists emphasized with unprecedented success the virtues of stockpiling notes on large scales and for the long term, thanks to the availability of paper and a new abundance of books, but also to (...) their ability to transmit their own keen motivation to avoid any future loss of learning. We continue to share many early modern ideals for insuring the collection and retrievability of information and have built on early modern practices that facilitate the accumulation and the organization of information, including collaborative work and the use of rearrangeable slips.

ABSTRACT:Since the dawn of capitalism, corporations have been regarded by the law as separate legal “persons.” Corporate “personhood” has nonetheless remained controversial, and our understanding of corporate personhood often influences our thinking about the social responsibilities of corporations. This essay, written in honor of Prof. Thomas Donaldson, explores the tension in recent decisions by the U.S. Supreme Court and the Delaware Chancery Court about what corporations are, whose interests they serve, and who gets to make decisions about what they do. (...) These decisions suggest that the law does not unequivocally support Donaldson’s vision of corporations as “moral” persons. (shrink)

This study investigates the ability of individuals with psychopathy to perform passive avoidance learning and whether this ability is modulated by level of reinforcement/punishment. Nineteen psychopathic and 21 comparison individuals, as defined by the Hare Psychopathy Checklist Revised (Hare, 1991), were given a passive avoidance task with a graded reinforcement schedule. Response to each rewarding number gained a point reward specific to that number (i.e., 1, 700, 1400 or 2000 points). Response to each punishing number lost a point punishment specific (...) to that number (i.e., the loss of 1, 700, 1400 or 2000 points). In line with predictions, individuals with psychopathy made more passive avoidance errors than the comparison individuals. In addition, while the performance of both groups was modulated by level of reward, only the performance of the comparison population was modulated by level of punishment. The results are interpreted with reference to a computational account of the emotional learning impairment in individuals with psychopathy. (shrink)

Many theories of complex cognitive-motor skill learning are built on the notion that basic cognitive processes group actions into easy-to-perform sequences. The present work examines predictions derived from laboratory-based studies of motor chunking and motor preparation using data collected from the real-time strategy video game StarCraft 2. We examined 996,163 action sequences in the telemetry data of 3,317 players across seven levels of skill. As predicted, the latency to the first action is delayed relative to the other actions in the (...) group. Other predictions, inspired by the memory drum theory of Henry and Rogers, received only weak support. (shrink)

In the tense religious climate of the late Renaissance (ca. 1550-1650), traditional charges of impiety directed against Aristotle carried new weight. Many turned to alternative philosophical authorities in the search for a truly pious philosophy. Another, "most pious" solution was to ground natural philosophy on a literal reading of the Bible, especially Genesis. I examine this kind of physics, often called Mosaic, or sacred, or Christian, through the example of Johann Amos Comenius and those whom he praises as predecessors in (...) his attempt to reform physics according to the "divine light" of Scripture. In analyzing the works of these authors, I conclude that what they shared most effectively was an agenda rather than a practice. They defended the single, universal truth of a "Christian philosophy" grounded in biblical literalism against the impious excesses of philosophical naturalism, on the one hand, and against the antiphilosophical attacks of extreme theologians, on the other hand. This peculiar strand of natural philosophy, neither traditional nor "modern," needs to be included in attempts to map the complex dynamics of contemporary debates and self-presentations. -/- .

In Logical Self-Defense , Johnson and I introduced the criteria of acceptability, relevance and sufficiency as appropriate for the evaluation of arguments in the sense of reasons offered in support of a claim. These three criteria have been widely adopted, but each has been subjected to a number of criticisms; and also 30 years of research have intervened. How do these criteria stand up today? In this paper I argue that they still have a place in argument analysis and evaluation, (...) but in much-modified roles. (shrink)

In Jonathan Adler argued that conductive arguments, as they are commonly characterized, are impossible—that no such argument can exist. This striking contention threatens to undermine a topic of argumentation theory originated by Trudy Govier based on Carl Wellman and revisited by the papers in “Conductive argument, An overlooked type of defeasible reasoning”. I here argue that Adler’s dismissal of conductive arguments relies on a misreading of the term ‘non-conclusive’ used in the characterization of this type of reasoning and argument, and (...) that as a result, his refutation fails. However, Adler’s critique raises other questions about conductive arguments that have to be answered. (shrink)

This study investigates the performance of psychopathic individuals on tasks believed to be sensitive to dorsolateral prefrontal and orbitofrontal cortex (OFC) functioning. Psychopathic and non-psychopathic individuals, as defined by the Hare psychopathy checklist revised (PCL-R) [Hare, The Hare psychopathy checklist revised, Toronto, Ontario: Multi-Health Systems, 1991] completed a gambling task [Cognition 50 (1994) 7] and the intradimensional/extradimensional (ID/ED) shift task [Nature 380 (1996) 69]. On the gambling task, psychopathic participants showed a global tendency to choose disadvantageously. Specifically, they showed an (...) impaired ability to show learning over the course of the task. On the ID/ED task, the performance of psychopathic individuals was not significantly different from incarcerated controls on attentional set-shifting, but significant impairments were found on response reversal. These results are interpreted with reference to an OFC and amygdala dysfunction explanation of psychopathy. (shrink)

Researchers have long suspected that grapheme-color synaesthesia is useful, but research on its utility has so far focused primarily on episodic memory and perceptual discrimination. Here we ask whether it can be harnessed during rule-based Category learning. Participants learned through trial and error to classify grapheme pairs that were organized into categories on the basis of their associated synaesthetic colors. The performance of synaesthetes was similar to non-synaesthetes viewing graphemes that were physically colored in the same way. Specifically, synaesthetes learned (...) to categorize stimuli effectively, they were able to transfer this learning to novel stimuli, and they falsely recognized grapheme-pair foils, all like non-synaesthetes viewing colored graphemes. These findings demonstrate that synaesthesia can be exploited when learning the kind of material taught in many classroom settings. (shrink)

Premissary relevance is a property of arguments understood as speech act complexes. It is explicable in terms of the idea of a premise's lending support to a conclusion. Premissary relevance is a function of premises belonging to a set which authoritatively warrants an inference to a conclusion. An authoritative inference warrant will have associated with it a conditional proposition which is true— that is to say, which can be justified. The study of the Aristotelian doctrine of topoi or argument schemes (...) may contribute to the task of identifying authoritative warrants. (shrink)

I argue that argumentation is not to be identified with (attempted) rational persuasion, because although rational persuasion appears to consist of arguments, some uses of arguments are not attempts at rational persuasion. However, the use of arguments in argumentative communication to try to persuade is one kind of attempt at rational persuasion. What makes it rational is that its informing ideal is to persuade on the basis of adequate grounds, grounds that make it reasonable and rational to accept the claim (...) at issue. (shrink)

This article surveys some of the ways in which early modern scholars responded to what they perceived as an overabundance of books. In addition to owning more books and applying selective judgment as well as renewed diligence to their reading and note-taking, scholars devised shortcuts, sometimes based on medieval antecedents. These shortcuts included the use of the alphabetical index, whether printed or handmade, to read a book in parts, and the use of reference books, amanuenses, abbreviations, or the cutting and (...) pasting from printed or manuscript sources to save time and effort in note-taking.

Recent interest in emotion as the basis for moral development began with work involving individuals with psychopathic tendencies, and a recent paper with this population has allowed fresh insights (Glenn, Iyer, Graham, Koleva, & Haidt, 2009). Two main conclusions suggested by this paper are: (i) that systems involved in different forms of morality can be differentiated; and (ii) that systems involved in justice reasoning likely include amygdala and/or ventromedial prefrontal cortex, even if the specifics of their functional contribution to justice (...) development remain unidentified.

In “Are conductive arguments possible?” Jonathan Adler argued that conductive argu-ments are not possible because they are committed to two incompatible propositions: C is reached without nullifying the counter-considerations; C is accepted is true, which issues in belief, so C is detached from these premises. This paper offers an analysis and an assessment of Adler’s case for his thesis.

In lieu of an abstract, here is a brief excerpt of the content:What Emotional Responding Is to Blame It Might Not Be to ResponsibilityR. J. R. Blair (bio)Keywordsblame, responsibility, emotional responses, psychopathyIn this interesting paper, Levy argues that by failing the moral/conventional distinction task (Blair 1995), individuals with psychopathy show a fundamental inability to categorize moral harms and as such their moral responsibility for their actions is reduced. He argues that, although we might still wish to incarcerate such individuals to (...) prevent them inflicting further harm on others, we should be less enthusiastic to blame them for their actions.In many respects, I agree with much of Levy's treatise. I certainly do not regard ascriptions of blame as useful in my own work with this population. I believe that our goal should be to fully understand the nature of their emotional deficit to be able to treat it similarly to other researchers who work to treat other emotional disorders. To me, Levy's argument appears sound.However, I offer three considerations and raise questions within these considerations that might further the debate. First, not all rules involve care-based emotional responses to victims. As Levy notes, this is the origin of the moral/conventional distinction. The problem here is that we do consider someone responsible if they break a conventional transgression. The student talking in class is generally considered blameworthy for this action as long as they knew that the rule of not talking during the lesson applied to that classroom. Yet, there is no victim and no care-based emotional response. Here, the only thing necessary to ascribe blame and responsibility is that the individual knew that a rule exists. Given this holds for conventional transgressions, why must we necessarily make a special case, with respect to responsibility, for moral transgressions?I believe that Levy is fully aware of this concern. He specifically makes reference to moral responsibility and writes that:the kind and degree of wrongness, and therefore blame, which attaches to infringements of the rules [against double parking or line-jumping] is very different, and usually much less significant, than the kind and degree attaching to moral wrongs. For psychopaths, all offences are merely conventional, and therefore—from their point of view—none of them are all that serious.(2007, p. 132)But the danger here is that issues of blame and responsibility may become highly relativistic and hinge on the strength of the emotional reaction. This is a problem because, although we might judge someone as more blameworthy if he intentionally [End Page 149] runs over five people rather than one, do we really consider that there is a distinction in moral responsibility between these two cases? If not, might not responsibility relate to factual knowledge of the existence of the rule against the transgression rather than the emotional response to the transgression?Second, there is considerable debate regarding whether psychopathy represents a taxon or a continuum (e.g., Vasey et al. 2005; Edens et al. 2006). Assuming it does represent a continuum, then we have an additional concern. How little of an emotional response to the transgression reduces one's moral responsibility and blame? Is it only the very reduced (although usually not absent) levels of emotional response that are shown by individuals with psychopathy? Or should we consider moral responsibility and blame proportional to the level of the emotional response? If this latter option is adopted, then what should we do about individuals who show heightened emotional responses, for example, patients with specific anxiety disorders (Rauch, Shin, and Wright 2003)? There are already some data that inhibited children (a developmental precursor to some anxiety disorders; Kagan and Snidman 1999) show heightened conscience development (Asendorpf and Nunner-Winkler 1992). If such children commit moral transgressions, should we regard them as more morally responsible and more blameworthy than regular folks?Third, the issue of intention received little attention in this paper. I have been considered to show a similar lack of attention to intention in the past (Nichols 2002) and, moreover, in some respects the issue was of limited concern given Levy's main goals. However, I mention it because so much of whether we consider someone responsible for their actions and... (shrink)

Youths with disruptive behavior disorders and psychopathic traits showed reduced amygdala responses to fearful expressions under low attentional load but no indications of increased recruitment of regions implicated in top- down attentional control. These findings suggest that the emotional deficit observed in youths with disruptive behavior disorders and psychopathic traits is primary and not secondary to increased top- down attention to nonemotional stimulus features.
