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)

It is usually supposed that the Dirac and radiation equations predict that the phase of a fermion will rotate through half the angle through which the fermion is rotated, which means, via the measured dynamical and geometrical phase factors, that the fermion must have a half-integral spin. We demonstrate that this is not the case and that the identical relativistic quantum mechanics can also be derived with the phase of the fermion rotating through the same angle as does the fermion (...) itself. Under spatial rotation and Lorentz transformation the bispinor transforms as a four-vector like the potential and Dirac current. Previous attempts to provide this form of transformational behavior have foundered because a satisfactory current could not be derived.(14). (shrink)

Pancreatitis is a complex, progressively destructive inflammatory disorder. Alcohol was long thought to be the primary causative agent, but genetic contributions have been of interest since the discovery that rare PRSS1, CFTR and SPINK1 variants were associated with pancreatitis risk. We now report two associations at genome-wide significance identified and replicated at PRSS1-PRSS2 and X-linked CLDN2 through a two-stage genome-wide study. The PRSS1 variant likely affects disease susceptibility by altering expression of the primary trypsinogen gene. The CLDN2 risk allele is (...) associated with atypical localization of claudin-2 in pancreatic acinar cells. The homozygous CLDN2 genotype confers the greatest risk, and its alleles interact with alcohol consumption to amplify risk. These results could partially explain the high frequency of alcohol-related pancreatitis in men. © 2012 Nature America, Inc. All rights reserved. (shrink)

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)

Highlighting previously neglected democratic strains in Machiavelli's major writings, McCormick excavates institutions through which the common people of ancient, medieval, and Renaissance republics constrained the power of wealthy citizens and public magistrates, and he imagines how such institutions might be revived today.

While we are commonly told that the distinctive method of mathematics is rigorous proof, and that the special topic of mathematics is abstract structure, there has been no agreement among mathematicians, logicians, or philosophers as to just what either of these assertions means. John P. Burgess clarifies the nature of mathematical rigor and of mathematical structure, and above all of the relation between the two, taking into account some of the latest developments in mathematics, including the rise of experimental (...) mathematics on the one hand and computerized formal proofs on the other hand. Along the way, a great many historical developments in mathematics, philosophy, and logic are surveyed. Yet very little in the way of background knowledge on the part of the reader is presupposed.

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)

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.

A new axiomatization of set theory, to be called Bernays-Boolos set theory, is introduced. Its background logic is the plural logic of Boolos, and its only positive set-theoretic existence axiom is a reflection principle of Bernays. It is a very simple system of axioms sufficient to obtain the usual axioms of ZFC, plus some large cardinals, and to reduce every question of plural logic to a question of set theory.

This is the first in-depth critical appraisal in English of the political, legal, and cultural writings of Carl Schmitt, perhaps this century's most brilliant critic of liberalism. It offers an assessment of this most sophisticated of fascist theorists without attempting either to apologise for or demonise him. Schmitt's Weimar writings confront the role of technology as it finds expression through the principles and practices of liberalism. Contemporary political conditions such as disaffection with liberalism and the rise of extremist political organizations (...) have rendered Schmitt's work both relevant and insightful. John McCormick examines why technology becomes a rallying cry for both right- and left-wing intellectuals at times when liberalism appears anachronistic, and shows the continuities between Weimar's ideological debates and those of our own age.

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)

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)

A revisionist account of how philosophical induction was conceived in the ancient world and how that conception was transmitted, altered, and then rediscovered. I show how philosophers of late antiquity and then the medieval period came step-by-step to seriously misunderstand Aristotle’s view of induction and how that mistake was reversed by humanists in the Renaissance and then especially by Francis Bacon. I show, naturally enough then, that in early modern science, Baconians were Aristotelians and Aristotelians were Baconians.

The great logician Gottlob Frege attempted to provide a purely logical foundation for mathematics. His system collapsed when Bertrand Russell discovered a contradiction in it. Thereafter, mathematicians and logicians, beginning with Russell himself, turned in other directions to look for a framework for modern abstract mathematics. Over the past couple of decades, however, logicians and philosophers have discovered that much more is salvageable from the rubble of Frege's system than had previously been assumed. A variety of repaired systems have been (...) proposed, each a consistent theory permitting the development of a significant portion of mathematics. This book surveys the assortment of methods put forth for fixing Frege's system, in an attempt to determine just how much of mathematics can be reconstructed in each. John Burgess considers every proposed fix, each with its distinctive philosophical advantages and drawbacks. These systems range from those barely able to reconstruct the rudiments of arithmetic to those that go well beyond the generally accepted axioms of set theory into the speculative realm of large cardinals. For the most part, Burgess finds that attempts to fix Frege do less than advertised to revive his system. This book will be the benchmark against which future analyses of the revival of Frege will be measured. (shrink)

Saul Kripke has made fundamental contributions to a variety of areas of logic, and his name is attached to a corresponding variety of objects and results. 1 For philosophers, by far the most important examples are ‘Kripke models’, which have been adopted as the standard type of models for modal and related non-classical logics. What follows is an elementary introduction to Kripke’s contributions in this area, intended to prepare the reader to tackle more formal treatments elsewhere.2 2. WHAT IS A (...) MODEL THEORY? Traditionally, a statement is regarded as logically valid if it is an instance of a logically valid form, where a form is regarded as logically valid if every instance is true. In modern logic, forms are represented by formulas involving letters and special symbols, and logicians seek therefore to define a notion of model and a notion of a formula’s truth in a model in such a way that every instance of a form will be true if and only if a formula representing that form is true in every model. Thus the unsurveyably vast range of instances can be replaced for purposes of logical evaluation by the range of models, which may be more tractable theoretically and perhaps practically. Consideration of the familiar case of classical sentential logic should make these ideas clear. Here a formula, say (p & q) ∨ ¬p ∨ ¬q, will be valid if for all statements P.. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Buddhist-Christian Studies 22 (2002) 139-147 [Access article in PDF] A Mahayana Theology of Salvation History John P. Keenan Middlebury College Salvation history is a Western theological strategy based on biblical ideas about how God acts in history to bring about the salvation/deliverance of God's people. It begins with the scriptural accounts of creation as the inception of God's plan. It moves to describe Israel's deliverance from slavery in (...) Egypt and goes on to depict the guidance the Lord Yahweh provides for his people throughout their journeys and despite their trials and reverses.Israel may be idealized in scripture as God's domain, sovereign among the nations, but in fact it was a small country sandwiched between the two superpowers of the day—Egypt and Assyria (or Babylon), and subject to the rise and fall of those empires. 1 The New Testament goes on to describe God's plan in sending his son Jesus to effect salvation and unite all people in him (Eph. 1:1-16). The passion, death, and resurrection of Jesus comprise the central drama, in which we all are invited to participate. The author of Luke/Acts gives an account of how God moves through the teachings and the life and death of Jesus to establish his Church and how that Church evolves from a small and marginal community to enter and permeate the very heart of the Empire at Rome. The story continues in postscriptural Christian history, from Constantine's vision at Milvian Bridge to the Christianization of Europe, and further to the missionary endeavors to convert all peoples to the path of the Gospel. In the twentieth century, Liberation theology is heir to these notions, insisting that conversion means not simply becoming Christian, but the furtherance of justice and peace among all peoples, even non-Christians.A Mahayana reading of this schema is not at first glance very promising. Mahayana knows nothing of God, much less of God acting in history. Nor, indeed, of history itself as a purposeful unfolding of events. Indian thought is known for its ahistoricity. No histories were produced in ancient India at all. No Herodotus, no Thucydides. The first Buddhist histories were written not in India but in Tibet, some thousand years after the birth of the Buddha Sakyamuni. Indian traditions in their focus on the eternal truth (sanatana dharma) turned away from the concrete flow of events and from any recording of their progression. [End Page 139]The task before us is challenging. To tackle it best, I will divide this essay into three parts, and thus attempt to argue for a Mahayana reading of salvation history. The first part will treat Mahayana philosophy and argue that despite its Indian lack of historical consciousness, it does possess the tools for writing history. Its teaching that all events are empty (sunyata) is coterminous with its teaching that all events arise in dependence upon a host of causes and conditions (pratitya-samutpada). In a word, emptiness itself entails a radical insight into the contingent and conventional historicity of events (dharmas). Beyond this, since all events are seen as empty of any abiding core essence, Mahayana deconstructs the very idea of an eternal world truth over and apart from the everyday world of events. It proclaims, rather, that to an awakened person, all is "worldly convention-only" (samvrti-matra). 2 This focus on the radical conventionality of events can serve, I would argue, as a needed corrective to a literalistic reading of salvation history. Looked at from this perspective, the story of the New Testament writers can perhaps become more apparent—how they are writing of God's design, purpose, and plan in order to counter the regnant patterns of Greek and Roman arrogance, and to substitute insight into the mystery of our being and of our being here.The second part of this article will address the Western doctrine of salvation history, focusing on the New Testament, particularly Pauline theology as expressed in one passage from Ephesians about how salvation is attained through Jesus as the unfolding plan of God's purpose...

The English word 'curriculum' is derived from the Latin word curriculum meaning 'a course', 'a race' or 'a running'. This suggests a process, the idea of going through something which has a beginning, a development and an end. The secondary meaning of curriculum was 'career'. Both the primary and the secondary meanings of curriculum referred to temporal space and to non-temporal endeavours or intellectual pursuits. The expression 'curriculum vitae', then referred to both intellectual and non-intellectual pursuits. Today curriculum in the (...) educational context refers primarily, if not solely, to intellectual pursuits. Actually curriculum is related to learning in a broad sense, incorporating more than the "cognitive" aspect. This suggests that the concept curriculum is a complex notion. Various meanings have been attached to it. A careful analysis of curriculum shows that the notions of "plan", "content or subject matter", "objectives" and "method" are intimately connected to curriculum which should not be completely identified with any one of these concepts. In this short paper I propose to discuss the following question: Is the notion of subject matter inherent in that of curriculum, or, does the notion curriculum make sense without that of subject matter? Answers to this question are meant to help clarify the relationship between the curriculum and subject matter. (shrink)

Saul Kripke has been a major influence on analytic philosophy and allied fields for a half-century and more. His early masterpiece, Naming and Necessity, reversed the pattern of two centuries of philosophizing about the necessary and the contingent. Although much of his work remains unpublished, several major essays have now appeared in print, most recently in his long-awaited collection Philosophical Troubles. In this book Kripke’s long-time colleague, the logician and philosopher John P. Burgess, offers a thorough and self-contained guide (...) to all of Kripke’s published books and his most important philosophical papers, old and new. It also provides an authoritative but non-technical account of Kripke’s influential contributions to the study of modal logic and logical paradoxes. Although Kripke has been anything but a system-builder, Burgess expertly uncovers the connections between different parts of his oeuvre. Kripke is shown grappling, often in opposition to existing traditions, with mysteries surrounding the nature of necessity, rule-following, and the conscious mind, as well as with intricate and intriguing puzzles about identity, belief and self-reference. Clearly contextualizing the full range of Kripke’s work, Burgess outlines, summarizes and surveys the issues raised by each of the philosopher’s major publications. Kripke will be essential reading for anyone interested in the work of one of analytic philosophy’s greatest living thinkers. (shrink)

In order to sketch an account of a moral commitment to persons as such, the essay examines empathy, sympathy, and benevolence as they arise first in special relations and then are reconstructed to include the stranger under the rubric of "extensive benevolence" or "universal love." The account, the author argues, must deal with conceptual empowerment and authorizing reasons, weakness and evil, normative conflict, and the relation of benevolence to justice.
