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)

_The Sceptics_ is the first comprehensive, up-to-date treatment of Greek scepticism, from the beginnings of epistemology with Xenophanes, to the final full development of Pyrrhonism as presented in the work of Sextus Empiricus. Tracing the evolution of scepticism from 500 B.C to A.D 200, this clear and rigorous analysis presents the arguments of the Greek sceptics in their historical context and provides an in-depth study of the various strands of the sceptical tradition.

In this paper I argue that human pattern recognition can be simulated by automata. In particular, I show that gestalt recognition and recognition of family resemblances are within the capabilities of sufficiently complex Turing machines. The argument rests on elementary facts of automata and computability theory which are used to explicate our preanalytic, informal concepts concerning gestalt patterns and recognition. The central idea is that of a machine which "knows" its own structure. Although the paper thus aims to support mechanism, (...) especially as a framework hypothesis for perception, it contains suggestions for philosophy of science and philosophy of language as well. Some of these suggestions are sketched in the final section. (shrink)

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.

We provide a justification for political liberalism’s Reciprocity Principle, which states that political decisions must be justified exclusively on the basis of considerations that all reasonable citizens can reasonably be expected to accept. The standard argument for the Reciprocity Principle grounds it in a requirement of respect for persons. We argue for a different, but compatible, justification: the Reciprocity Principle is justified because it makes possible a desirable kind of political community. The general endorsement of the Reciprocity Principle, we will (...) argue, helps realize joint political rule and relationships of civic friendship. The main obstacle to the realization of these values is the presence of reasonable disagreement about religious, moral, and philosophical issues characteristic of liberal societies. We show the Reciprocity Principle helps to overcome this obstacle. (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)

David Hume (1711–1776) believed a ‘confederacy of authors’, brought together by the notoriously pugnacious William Warburton (1698–1779), were his most consistent and scurrilous critics. Warburton and his ‘School’ were Hume’s bêtes noires and embodied so much of what he fought against. Only there is reason to believe that the ‘Warburtonian School’ was more a useful fiction than a historical reality. The following deep dive into Humeana and the ‘stuff of anecdote’ digs up substantial conclusions about Hume’s philosophical project and context. (...) Any glorifying picture of Hume admirably ignoring sustained ‘Warburtonian’ name-calling is not an accurate description of the early reception of his writings. Hume did respond – at least, occasionally, privately and publicly. Moreover, the ‘Warburtonian School’ does not seem to exist – at least, it did not exist if it is taken to refer to a coherent group of writers, numbering more than two, concerned with attacking Hume. The response to Hume of ‘Warburtonians’ who can be identified was varied, disparate, and often positive. Warburton even came to like Hume’s historical writings. Hume’s claim that such a School existed may have led to the post hoc creation of the School in the minds of late eighteenth- and nineteenth-century commentators. (shrink)

Political liberals ask citizens not to appeal to certain considerations, including religious and philosophical convictions, in political deliberation. We argue that political liberals must include a demanding requirement of intellectual modesty in their ideal of citizenship in order to motivate this deliberative restraint. The requirement calls on each citizen to believe that the best reasoners disagree about the considerations that she is barred from appealing to. Along the way, we clarify how requirements of intellectual modesty relate to moral reasons for (...) deliberative restraint. And we argue against attempts to weaken our requirement of intellectual modesty by emphasizing those moral reasons. (shrink)

SummaryThis article argues that Archibald Campbell's Necessity of Revelation can be viewed as the first application of the ‘science of human nature’, a characteristic branch of the Scottish Enlightenment, to the study of religious belief. Adopting Baconian and Newtonian methodological principles, Campbell set hypotheses, collected historical data, and inferred conclusions about the capabilities of human nature to come to fundamental religious ideas without the aid of revelation. He did so not only to reject the ‘deist’ position on the powers of (...) unassisted human reason, associated with Matthew Tindal's Christianity as Old as the Creation, but also to refute Campbell's conservative critics within the Church of Scotland who had earlier tried him for heresy. Campbell's example is that of a university professor using the experimental study of religion to defeat both radical freethinking and Calvinist orthodoxy. His work is another instance of the complicated relationship between science and religion within eighteenth-century Scotland. (shrink)

ABSTRACT The Scottish judge and ‘eccentric’ philosopher James Burnett, Lord Monboddo’s (1714–1799) significance within Enlightenment thought is usually seen as stemming from his Origin and Progress of Language (6 vols., 1773–1792). The OPL was a major contribution to the Enlightenment’s debate over the philosophy of language, and established Monboddo’s reputation as an innovative and influential, yet controversial and credulous proto-anthropologist. In the following I explore Monboddo’s Egyptomania and the role it plays in his account of the origins and development of (...) religion within his larger ‘History of Man’. Monboddo’s idiosyncratic and untimely fusion of conjectural history, Buffon-inspired natural history, Christian theology, Platonic and Aristotelian philosophy and credulous interest in Egyptology, especially in Antient Metaphysics (6 vols., 1779–1799), make him extremely difficult to place within the Scottish Enlightenment. I want to bring Monboddo back into our conversation about the Scottish Enlightenment, shed light in the process on his highly idiosyncratic combination of enlightened and unenlightened thought and, using Monboddo’s example, emphasize some interesting if unexpected aspects of the Scottish Enlightenment’s application of the ‘science of human nature’ to the study of religion. For Monboddo, human civilization and religious knowledge owes their existence to Egyptian daemon-kings. (shrink)
