Replicating or exceeding human intelligence, not just in particular domains but in general, has always been a major goal of Artificial Intelligence (AI). We argue here that “human intelligence” is not only ill-defined, but often conflated with broader aspects of human psychology. Standard arguments for replicating it are morally unacceptable. We then suggest a reframing: that the proper goal of AI is not to replicate humans, but to complement them by creating diverse intelligences capable of collaborating with humans. This goal (...) renders issues of theory of mind, empathy, and caring, or community engagement, central to AI. It also challenges AI to better understand the circumstances in which human intelligence, including human moral intelligence, fails. (shrink)

Today there appears to be a widespread impression that W. V. Quine's notorious critique of modal logic, based on certain ideas about reference, has been successfully answered. As one writer put it some years ago: “His objections have been dead for a while, even though they have not yet been completely buried.” What is supposed to have killed off the critique? Some would cite the development of a new ‘possible-worlds’ model theory for modal logics in the 1960s; others, the development (...) of new ‘direct’ theories of reference for names in the 1970s.These developments do suggest that Quine's unfriendliness towards any formal logics but the classical and indifference towards theories of reference for any singular terms but variables were unfortunate.

Darwinism, Democracy, and Race examines the development and defence of an argument that arose at the boundary between anthropology and evolutionary biology in twentieth-century America. In its fully articulated form, this argument simultaneously discredited scientific racism and defended free human agency in Darwinian terms. The volume is timely because it gives readers a key to assessing contemporary debates about the biology of race. By working across disciplinary lines, the book's focal figures--the anthropologist Franz Boas, the cultural anthropologist Alfred Kroeber, the (...) geneticist Theodosius Dobzhansky, and the physical anthropologist Sherwood Washburn--found increasingly persuasive ways of cutting between genetic determinist and social constructionist views of race by grounding Boas's racially egalitarian, culturally relativistic, and democratically pluralistic ethic in a distinctive version of the genetic theory of natural selection. Collaborators in making and defending this argument included Ashley Montagu, Stephen Jay Gould, and Richard Lewontin. Darwinism, Democracy, and Race will appeal to advanced undergraduates, graduate students, and academics interested in subjects including Philosophy, Critical Race Theory, Sociology of Race, History of Biology and Anthropology, and Rhetoric of Science.

In lieu of an abstract, here is a brief excerpt of the content:John P. Anton C. P. CAVAFY'S ARS POETICA ' It is generally recognized that Constantine P. Cavafy (1863-1933) was not born a poet but became one only through persistence and labor, reaching his "first step" sometime after the midpoint of his life. In his effort to assess the quality of his earlier poetic production and sharpen his sensitivity in facing self-criticism, he decided to put in writing his (...) personal thoughts on his work sometime in 1903. The text was written in English in a personal shorthand Cavafy had devised for his own use. It was found among the papers he left to A. Sengopoulos and published for the first time in 1963 by M. Peridis, who also supplied the suitable title Ars Poetica. It falls outside the scope of this essay to discuss the antecedents of this document. Taken as a whole, the text has all the clarity and directness required of a testament designed to serve as a personal guide and handbook. The problems it discusses are limited to the needs of the poet. In this regard, the Ars Poetica has neither the range of topics nor the theoretical scope of, for instance, Aristotle's Poetics. It is quite certain that the ideas that preoccupy Cavafy in the Ars Poetica had been on his mind for a period of years. However, the Ars Poetica is his first prose piece where he gives a systematic treatment to technical and critical issues directly related to the assessment of his work and his role as a poet. In order to project here a clear image of Cavafy's struggle to reach his technical maturity which came after 1910, we need first to discuss the persistent problems he faced during this crucial decade, then to examine the attitudes and values he embodied in certain representative early poems, and finally to relate them to the guiding principles he formulated in his self-addressed poetics of 1903. A number of interrelated problems confronted Cavafy in his late twenties and throughout his thirties. They emerged one by one, to 85 86Philosophy and Literature make more pressing the demand for a consistent solution and a complete recasting of his outlook. Coming to terms with them was extremely difficult. Aside from the emotional and sexual pressures he had to face alone, there was the absence of suitable ideas and conceptual tools to provide him with even the rudiments of an intellectual framework. Whatever he borrowed from Europe and England, or resurrected from his own Hellenic heritage, proved either beyond assimilation or insufficiently digested. The lingering issues fell roughly into four areas. (i) Despite his determination to devote his life to the writing of poetry, the quality of his work was discouraging. He knew this and as a result he often expressed uncertainty about his ability to proceed. Time and again he appeared suffering from a feeling of inadequacy, but nevertheless he sought to engage a reflective mood from which to draw encouragement and hope. (ii) On the theoretical side, he identified with the long tradition which assigned a coveted cultural role to the savant-poet as discloser of truth and spokesman for humanity; this despite the prevailing climate of opinion in his immediate environment which recognized no such high position in his case. Cavafy knew that his standing with the Greek community of Alexandria had gradually dwindled with the loss of family wealth and his lowly employment, and also that his expectations to be respected in his role as a poet and leader in communal affairs were futile. This denial of personal recognition in a society dominated by commerce and finance contributed to his mood of depression. The feeling of being an outcast, despite his associations with the upper social circles of Alexandria, became a constant irritant to his sense of pride. (iii) The course of culture, the destiny of human institutions and the workings of history, became puzzles as he tried to view them through the opaque glass of disillusionment. These were the grand themes actively discussed in the writings of leading European intellectuals, but to the young poet they had a different personal urgency. His vital concern in this connection was not understanding science... (shrink)

This paper is the second of a multi-part examination of the creation of the Babylonian mathematical lunar theories known as Systems A and B. Part I (Britton 2007) addressed the development of the empirical elements needed to separate the effects of lunar and solar anomaly on the intervals between syzygies. This was accomplished in the construction of the System A lunar theory by an unknown author, almost certainly in the city of Babylon and probably early in the 4th century B.C. (...) The present paper focuses mainly on System A and the likely process of its construction. The first three sections are largely descriptive – first of the basic concepts which underlie the theory; then of the component schemes comprising the theory; and finally of two distinctive texts which suggest how the theory was constructed. The crux of the paper is Sect. 4, which describes how the theory seems likely to have been constructed. Here the crucial insight in separating the effects of lunar and solar anomaly appears to have been recognizing that – of all the measurable intervals bounded by eclipses – only 235 months exhibits a variation due solely to lunar anomaly, and that by means of an elegant mathematical model the amplitudes of 223 and 12 months could be deduced from its amplitude. The rest of the section describes the likely details of the derivation of the Φ ~ Λ scheme, and the extension of the methodology to the other components of the theory. It concludes with a demonstration that Φ and its dependent schemes were anchored through the Φ ~ W scheme to the syzygy on –403 Aug 18 (GN 7391) which concluded the shortest 6-month interval in the first 24 saros cycles since –746 (and in fact in the 900 years separating Nabonassar and Ptolemy). The next three sections address a number of largely technical details and amplifications of the theory, beginning with the schemes describing the variation of lunar velocity (column F) in Sect. 5. Section 6 addresses issues concerning the interpretation of Φ and the so-call Saros Text (BM 36705), while Sect. 7 discusses System B’s corresponding treatment of the effects of lunar anomaly, illustrating both its derivative nature and mathematically less rigorous structure. Section 8 examines the accuracy of the two theories, showing that the System A theory was both remarkably accurate and superior to System B. The final section offers some brief remarks on the power and elegance of the mathematical treatment of the problem by the author of System A. (shrink)

By utilizing new information from both clinical and experimental (lesion, electrophysiological, and gene-activation) studies with animals, the anatomy underlying anterograde amnesia has been reformulated. The distinction between temporal lobe and diencephalic amnesia is of limited value in that a common feature of anterograde amnesia is damage to part of an comprising the hippocampus, the fornix, the mamillary bodies, and the anterior thalamic nuclei. This view, which can be traced back to Delay and Brion (1969), differs from other recent models in (...) placing critical importance on the efferents from the hippocampus via the fornix to the diencephalon. These are necessary for the encoding and, hence, the effective subsequent recall of episodic memory. An additional feature of this hippocampalanterior thalamic and the perirhinal–medial dorsal thalamic systems are compromised, leading to severe deficits in both recall and recognition. (shrink)

This paper challenges the recommendation of 1981 President's Commission for the Study of Ethical Problems in Medicine and Biomedical and Behavioral Research that all jurisdictions in the United States should adopt the Uniform Determination of Death Act, which endorses a whole-brain, rather than a higher-brain, definition of death. I argue that the Commission was wrong to reject the "personhood argument" for the higher-brain definition on the grounds that there is no consensus among philosophers or the general population as to what (...) constitutes "personhood". I claim that philosophers agree that some potential for cognitive function is necessary for personhood and that, when this is absent in cases of anencephaly and persistent vegetative state (PVS), the individual should be considered dead. I further argue that the lack of consensus among the general population is due in large measure to misunderstandings about the medical reality of PVS and beliefs influenced by feelings for a specific individual in PVS. I also examine and reject two tutiorist arguments which have been used to support the Commission's position: that the higher-brain definition would threaten the severely senile and severely retarded, and that there are not currently adequate medical techniques for determining when all higher-brain activities have ceased.

How far does a researcher’s responsibility extend when an incidental finding is identified? Balancing pertinent ethical principles such as beneficence, respect for persons, and duty to rescue is not always straightforward, particularly in neuroimaging research where empirical data that might help guide decision making are lacking. We conducted a systematic survey of perceptions and preferences of 396 investigators, research participants, and Institutional Review Board members at our institution. Using the partial entrustment model as described by Richardson, we argue that our (...) data supports universal reading by a neuroradiologist of all research MRI scans for incidental findings and providing full disclosure to all participants.

In lieu of an abstract, here is a brief excerpt of the content:Hume Studies Volume 29, Number 1, April 2003, pp. 125-141 Dr. George Cheyne, Chevalier Ramsay, and Hume's Letter to a Physician JOHN P. WRIGHT The publication of a new intellectual biography of George Cheyne1 provides a "propitious" occasion for "a thoroughly skeptical review"2 of the question which has long exercised Hume scholars, whether Cheyne was the intended recipient of David Hume's fascinating pie-Treatise Letter to a Physician,3 the (...) letter which describes his own hypochondriacal physical and mental symptoms and gives an account of his early philosophical development.4 Hume's nineteenth-century biographer, John Hill Burton, argued that Hume was probably writing to Cheyne,5 while Ernest Mossner claimed to definitively refute that hypothesis in an article entitled "Hume's Epistle to Dr. Arbuthnot," published in 1944.6 Anita Guerrini's intellectual biography does not discuss Cheyne as a possible recipient of Hume's letter, but she does present a well-rounded picture of this interesting eighteenth-century physician from which we can judge his appropriateness as its addressee. In the following discussion I will make use of the biographical material found in this new biography of Cheyne, as well as other sources, to show that Mossner's arguments are less than definitive, and that it would be wrong to dismiss the possibility that the letter was sent to George Cheyne.7 This is a possibility that, for reasons that I will make clear, makes good biographical and philosophical sense. At the same time, it is important to keep a proper suspense of judgment as Burton did, for the evidence that the letter was either intended for or actually sent to Cheyne is not definitive. John P. Wright is Professor of Philosophy, Central Michigan University, Mt. Pleasant, MI 48859, USA. e-mail: [email protected] 126 John P. Wright Burton, who first published the autobiographical letter of the 22-yearold Hume in 1846, narrowed down the possible addressees of Hume's letter to either Cheyne or John Arbuthnot. He also pointed out that it is possible that the letter was never sent, and that the ten and a half page manuscript is only a neatly written draft, rather than a fair copy of an actual letter. Nevertheless, Burton thought he could identify the unnamed addressee on the basis of the internal evidence of the manuscript and the records of Scottish physicians practicing in England at the time. In the letter, Hume refers to the intended recipient as his "Countryman, a Scotchman [,]... a skilful Physician, a man of Letters, of Wit, of Good Sense, & of great Humanity."8 Further he writes that he is consulting him because he is a person "of great Learning beyond [his]... own Profession" who is acquainted with the "Motions of the Mind" he has described in his letter, and that "Fame pointed [him]... out as the properest person to resolve my Doubts..." about the cure of his disorder.9 Burton tells us that "the first name that suggested itself... was Arbuthnot, whose fine genius was just then flickering in the socket."10 (John Arbuthnot had been ill for some time, and died a year later.) But he then added that "a more full consideration showed to my satisfaction that it must have been destined for Dr. George Cheyne." His main reason for settling on Cheyne was that Cheyne's immensely popular The English Malady (1733) had recently been published, and that "there is a certain unison of tone between Hume's letter and this book." Burton quotes a portion of Cheyne's own long autobiographical account of his own disease in The English Malady. Cheyne's autobiography begins with the claim that "I passed my Youth in close study, and almost constant Application to the abstracted Sciences, (wherein my chief pleasure consisted) and consequently in great Temperance and a Sedentary Life"; it is followed by the reflection that any overindulgence in food or drink led to physical and psychological problems.11 He goes on to describe these in great detail for 39 pages, along with a history of his life. Burton also quotes a section of the book in which Cheyne describes how a studious and sedentary life causes the symptoms... (shrink)

As the expansion of the Internet and the digital formatting of all kinds of creative works move us further into the information age, intellectual property issues have become paramount. Computer programs costing thousands of research dollars are now copied in an instant. People who would recoil at the thought of stealing cars, computers, or VCRs regularly steal software or copy their favorite music from a friend's CD. Since the Web has no national boundaries, these issues are international concerns. The contributors-philosophers, (...) legal theorists, and business scholars, among others-address questions such as: Can abstract ideas be owned? How does the violation of intellectual property rights compare to the violation of physical property rights? Can computer software and other digital information be protected? And how should legal systems accommodate the ownership of intellectual property in an information age? Intellectual Property is a lively examination of these and other issues, and an invaluable resource for librarians, lawyers, businesspeople, and scholars. (shrink)

David Hume's A Treatise of Human Nature presents the most important account of skepticism in the history of modern philosophy. In this lucid and thorough introduction to the work, John P. Wright examines the development of Hume's ideas in the Treatise, their relation to eighteenth-century theories of the imagination and passions, and the reception they received when Hume published the Treatise. He explains Hume's arguments concerning the inability of reason to establish the basic beliefs which underlie science and morals, (...) as well as his arguments showing why we are nevertheless psychologically compelled to accept such beliefs. The book will be a valuable guide for those seeking to understand the nature of modern skepticism and its connection with the founding of the human sciences during the Enlightenment. (shrink)

The integrative memory model contains multiple subsystems. In this commentary, the processes within these subsystems are questioned. First, the assumption that familiarity largely reflects perceptual fluency is examined. Next, the distinction between “process” and “representational” models of temporal lobe function is challenged. Finally, the “relational representation core system”, which is central to the model, is especially sketchy. Here, I highlight key questions to be addressed in order to understand this system's role in trace formation.

It is striking that one of the most consequential representatives of [the] abstract scientific orientation of the seventeenth century [Thomas Hobbes] became so personalistic. This is because as a juristic thinker he wanted to grasp the reality of societal life just as much as he, as a philosopher and a natural scientist, wanted to grasp the reality of nature.... [J]uristic thought in those days had not yet become so overpowered by the natural sciences that he, in the intensity of his (...) scientific approach, should unsuspectingly have overlooked the specific reality of legal life. Carl Schmitt, Political Theology (1922)In the light of Hobbes's natural science, man and his works become a mere phantasmagoria. Through Hobbes's natural science, “the native hue” of his political science “is sicklied o'er with the pale cast” of something which is reminiscent of death but utterly lacks the majesty of death—of something which foreshadows the positivism of our day. It seems then that if we want to do justice to the life which vibrates in Hobbes's political teaching, we must understand that teaching by itself, and not in the light of his natural science. Can this be done?² Leo Strauss, “On the Basis ofHobbes's Political Philosophy” (1959). (shrink)

Scientific authorship has become a contested terrain in contemporary science. Based on a survey of authors across fields, we measure the likelihood of specialist authors : people who only made specialized contributions, such as data, materials, or funding; and “nonauthor collaborators” : those who did significant work on the project but do not appear as authors, across different research contexts, including field, size of the project team, commercial orientation, impact of publication, and organization of the collaboration. We find that guest (...) and ghost authors are common, with about one-third of publications having at least one specialist author and over half having at least one nonauthor collaborator. We see significant cross-field variations in both overall rates and types of specialist authors and nonauthor collaborators. We find there are generally fewer specialist authors among highly cited papers and more graduate student nonauthor collaborators in single location projects. The results suggest authorship practices vary across fields, and by project characteristics, complicating the use of authorship lists as a basis for evaluation. We discuss implications of these findings for interpreting author lists in the context of science policy. (shrink)

Quine correctly argues that Carnap's distinction between internal and external questions rests on a distinction between analytic and synthetic, which Quine rejects. I argue that Quine needs something like Carnap's distinction to enable him to explain the obviousness of elementary mathematics, while at the same time continuing to maintain as he does that the ultimate ground for holding mathematics to be a body of truths lies in the contribution that mathematics makes to our overall scientific theory of the world. Quine's (...) arguments against the analytic/synthetic distinction, even if fully accepted, still leave room for a notion of pragmatic analyticity sufficient for the indicated purpose. (shrink)

Crowdfunding platforms have revolutionized entrepreneurial finance, with 200 billion dollars expected to be dispersed annually to entrepreneurs and small business owners by 2020. Despite the importance of this growing phenomenon, our knowledge of the dynamics of successful lending-based prosocial crowdfunding and its implications for the business ethics literature remain limited. We use a social responsibility lens to examine whether crowdfunders on a lending-based prosocial platform lend their money based on altruistic or strategic motives. Our results indicate that the dynamics of (...) prosocial lending-based crowdfunding are somewhat consistent with traditional forms of financing. Specifically, despite a prosocial setting in nature, crowdfunders tend to act strategically, positively responding to signals of quality and low risk. Notably, we also find that projects that are high on both financial and social appeal receive the highest average amount of funding. Furthermore, language on the lender’s profile indicating ability to pay is positively related to both funding success and funding amount. Our study contributes to filling the gap in the business ethics literature about the dynamics of lending-based prosocial crowdfunding, and the strategic and altruistic ethical motives that drive lenders in such endeavors.

This article addresses the demand for global content knowledge that the process of internationalization has placed on the preparation of social studies teachers. Drawing on scholarship about global perspectives in teacher education, this study examined what one cohort of preservice teachers learned about globalization during participation in a three-week, web-based, international relations simulation. The unit was part of a methods course designed to prepare preservice teachers to teach global issues and internationalize the curriculum. International simulations have long been touted as (...) a means for learning challenging knowledge about global issues yet are rarely studied in teacher education. This qualitative study drew on concept maps and written responses completed before and after the simulation to document the preservice teachers’ learning. The analysis generated two findings: (1) preservice teachers acquired a shared, conceptual vocabulary for globalization that included the events and actors represented in the simulation; and (2) they also demonstrated a more systematic and critical understanding of the ways that power and conflict shaped the events and actors. The study contributes to the question of what teachers need to know to teach with global perspectives and how efforts to internationalize teacher education programs can foster such knowledge.

The increasingly pervasive practice of veiling among Muslim women has stimulated a great deal of scholarly investigation and debate. This study brings empirical evidence to bear on current debates about the meaning of the veil in Islam. This article first examines the conflicting meanings of the veil among Muslim religious elites and Islamic feminists. Although the dominant gender discourse among Muslim elites strongly favors this cultural practice, an antiveiling discourse promulgated by Islamic feminists has gained ground within recent years. This (...) study then examines how these discursive disputes affect gender identity negotiation among veiled and unveiled Muslim women living in Austin, Texas. Interviews with these women highlight how their gender identities reproduce and reformulate existing Muslim gender discourses. Special attention is paid to the subjective disparities and points of congruence between both groups of respondents. This study concludes by suggesting avenues for future research on the intersection of gender, religion, and cultural difference. (shrink)

In 1956 Jacques Lacan proposed as interpretation of Edgar Allan Poe's "Purloined Letter" that at once challenged literary theorists and revealed a radically new conception of psychoanalysis. Lacan's far-reaching claims about language and truth provoked a vigorous critique by Jacques Derrida, whose essay in turn has spawned further responses from Barbara Johnson, Jane Gallop, Irene Harvey, Norman Holland, and others. The Purloined Poe brings Poe's story together with these readings to provide, in the words of the editors, "a structured exercuse (...) in the elaboration of textual interpretation.

The subsequent essays join the Lacan-Derrida debate and offer alternative readings by literary theorists, philosophers, psychologists, and psychoanalysts. The Purloined Poe convenes much of the most important current scholarship on "The Purloined Letter" and presents a rich sampling of poststructuralist discourse. (shrink)

Nominalism is the view that mathematical objects do not exist.

Some programs accord with naturalism, and some oppose naturalism. Steven Yablo’s fictionalism is brought into the fold and discussed at some length.

It is a fact of modern scientific thought that there is an enormous variety of logical systems - such as classical logic, intuitionist logic, temporal logic, and Hoare logic, to name but a few - which have originated in the areas of mathematical logic and computer science. In this book the author presents a systematic study of this rich harvest of logics via Tarski's well-known axiomatization of the notion of logical consequence. New and sometimes unorthodox treatments are given of the (...) underlying principles and construction of many-valued logics, the logic of inexactness, effective logics, and modal logics. Throughout, numerous historical and philosophical remarks illuminate both the development of the subject and show the motivating influences behind its development. Those with a modest acquaintance of modern formal logic will find this to be a readable and not too technical account which will demonstrate the current diversity and profusion of logics. In particular, undergraduate and postgraduate students in mathematics, philosophy, computer science, and artificial intelligence will enjoy this introductory survey of the field. (shrink)

In this first full-length study of male homosexuality in Cather's short stories and novels, John P. Anders examines patterns of male friendship ranging on a continuum from the social to the sexual. He reveals how Cather's work assumes an unexpected depth and complexity by drawing on both the familiar tradition of friendship literature inspired by classical and Christian texts and a homosexual legacy that is part of, yet distinct from, established literary traditions. Anders argues that Cather's artistic achievement is (...) distinguished by her sexual aesthetics, an elusive literary style inextricably associated with homosexuality. His analysis demonstrates how a homosexual ethos and eros helped Cather develop a sensitivity to human variation and a style to accommodate it and thus became the objective correlative of her art, dramatizing the diversity of human nature as it deepens the mystery of her work.

Neurobiology-based interventions for mental diseases and searches for useful biomarkers of treatment response have largely failed. Clinical trials should assess interventions related to environmental and social stressors, with long-term follow-up; social rather than biological endpoints; personalized outcomes; and suitable cluster, adaptive, and n-of-1 designs. Labor, education, financial, and other social/political decisions should be evaluated for their impacts on mental disease.
