The existence of non-standard numbers in first-order arithmetics is a semantic obstacle for modelling our arithmetical skills. This article argues that so far there is no adequate approach to overcome such a semantic obstacle, because we can also find out, and deal with, non-standard elements in Turing machines.

The Paradox of the Knower was originally presented by Kaplan and Montague [26] as a puzzle about the everyday notion of knowledge in the face of self-reference. The paradox shows that any theory extending Robinson arithmetic with a predicate K satisfying the factivity axiom K → A as well as a few other epistemically plausible principles is inconsistent. After surveying the background of the paradox, we will focus on a recent debate about the role of epistemic closure principles in the (...) Knower. We will suggest this debate sheds new light on the concept of knowledge which is at issue in the paradox – i.e. is it a “thin” notion divorced from concepts such as evidence or justification, or is it a “thick” notion more closely resembling mathematical provability? We will argue that a number of features of the paradox suggest that the latter option is more plausible. Along the way, we will provide a reconstruction of the paradox using a quantified extension of Artemovʼs [2] Logic of Proofs, as well as a series of results linking the original formulation of the paradox to reflection principles for formal arithmetic. On this basis, we will argue that while the Knower can be understood to motivate a distinction between levels of knowledge, it does not provide a rationale for recognizing a uniform hierarchy of knowledge predicates in the manner suggested by Anderson.

O conceito de distância é de fundamental importância para a Ciência. Basicamente, uma vez traduzida para a matemática, a noção de distância se define como uma função cujos argumentos são pares de números reais e os valores são números reais. Tal concepção de distância (o espaço métrico) está presente em todas as áreas da física, e tem por fundamento a ideia intuitiva de que a distância entre dois pontos é o tamanho de um caminho contínuo entre tais pontos. Este artigo (...) apresenta um novo conceito de distância, conceito este baseado nos números transreais, criados pelo cientista da computação James A.D.W. Anderson. Esta nova concepção de espaço métrico (o espaço transmétrico) permite a introdução de distâncias infinitas, assim como distâncias entre pontos entre os quais não há caminho contínuo algum (metaforicamente, uma distância cuja imagem é o “salto”).

In lieu of an abstract, here is a brief excerpt of the content:Kennedy Institute of Ethics Journal 14.3 (2004) vii-viii [Access article in PDF] John C. Fletcher 1931-2004 John Fletcher was one of the pioneers in the still-young field of bioethics. In this short tribute, I can only hope to highlight a few of the many contributions he made to the field.For many of us, our first introduction to John occurred in October 1971. At an international symposium sponsored by the (...) Kennedy Foundation, the film "Who Should Survive?" depicted the dramatic case of an infant with Down syndrome and an intestinal blockage. The parents of the infant refused surgery to relieve the obstruction, and the healthcare providers for the infant decided not to pursue a court order permitting the surgery. During a period of approximately two weeks the infant was allowed to die.In the second part of "Who Should Survive?" John was one of several panelists invited to discuss the decisions made in this case. After acknowledging how troubling the infant's death was to him, John nonetheless sought to be empathic with the parents. He pointed out that in the re-enactment of the case the faces of the parents were never seen, and he worried that the film did not permit the parents to discuss the reasons for the choice they had made. John realized that his position would not be shared by most other panelists. Yet he had the courage to take an unpopular stand and to challenge other panelists—and the audience—not to reach premature closure on complex ethical dilemmas.Already in 1967, John had begun contributing to the literature of bioethics. His essay "Human Experimentation: Ethics in the Consent Situation," appeared in Law and Contemporary Problems. At the time, John was deeply immersed in studying the ethical dimensions of research with human subjects at the NIH Clinical Center. Paul Ramsey cited John's work with appreciation in his 1970 book, The Patient as Person. By the time he completed his dissertation at Union Theological Seminary in 1969, John was arguably one of the best trained bioethicists in the world—before there was a field of bioethics.After serving as chaplain, teaching at Virginia Theological Seminary, and founding and leading a seminary without walls in Washington, DC, John became the chief of the ethics program at the NIH Clinical Center in 1977. There he had the unenviable task of providing a second review for all clinical protocols emerging from the intramural programs of the NIH institutes. John discovered that in some cases the institutional review boards of the institutes had overlooked important ethical questions. This role also [End Page vii] required courage. At times John found it necessary to challenge senior NIH researchers, even institute directors, and to request protocol revisions that in his view were required for the protection of human subjects.In 1980, after Martin Cline had performed an unauthorized gene transfer experiment involving thalassemia patients, John joined with physician W. French Anderson to write an essay entitled "Gene Therapy in Human Beings: When Is It Ethical to Begin?" [New England Journal of Medicine 303: 1293-97]. Not only did this essay help to defuse a potentially explosive problem for NIH, which had funded Cline's research. It also provided a set of guidelines for the conduct of human gene transfer research that is of continuing relevance today.At times John disagreed with federal policies on research, for example, conservative policies on human embryo research. He also chafed at the idea of subjecting his publications to prior NIH review, both for accuracy and for political correctness. Thus, he welcomed the opportunity to move to the University of Virginia in 1987. There his academic career flowered, and he enjoyed some of his most productive years of research and writing.Among his many contributions during these later years, John participated as Committee co-chair in an effort to "redress the wrongs of Tuskegee." The Tuskegee Syphilis Study Legacy Committee proposed in May 1996 that President Clinton apologize to the participants in the Tuskegee study on behalf of the federal government. In May 1997, the President did in... (shrink)

Nuclear power has never been free from the stifling involvement of government. Heavy regulation has reduced the ability of entrepreneurs to develop and provide new means for the generation of energy using nuclear fuel. The strict parameters dictated by government officials are based upon outdated technology, an improper regulatory philosophy, and preclude innovation in nuclear power generation. Anti-market environmentalists misunderstand the implications of a free market in nuclear power and argue against it based on problems that are actually caused by (...) government involvement. Our position is neither for nor against nuclear power. We advocate a hands-off policy where the nuclear industry is left to its own devices, free from governmental regulations and subsidies: free to succeed or fail on its own. Thus, our position is neither right-wing conservative (removing regulations), nor left-wing liberal (removing subsidies). Very much to the contrary of both positions, we propose a free-market in nuclear power. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Diacritics 29.4 (1999) 40-57 [Access article in PDF] Bogeyman: Benedict Anderson's "Derivative" Discourse Andrew Parker Between life and death, nationalism has as its own proper space the experience of haunting. There is no nationalism without some ghost. -Jacques Derrida, "Onto-Theology of National-Humanism" Writing a mere decade ago about Benedict Anderson's Imagined Communities, Timothy Brennan noted that "with the exception of some recent sociological works which use literary (...) theories, it is rare in English to see 'nation-ness' talked about as an imaginative vision--as a topic worthy of full fictional realization.... Even in the underrepresented branch of Third World English studies, one is likely to find discussions of race and colonialism, but not the 'nation' as such" [47]. If these sentences appear astonishing today--if over the past ten years we seem to have done little else but regard the nation as an imaginative construction--our sense of surprise may help to register how rapidly and profoundly Anderson's work has transformed the nature of literary and cultural studies. Viewing the modern nation primarily as an anthropological rather than political category, one that has less inherently to do with ideologies than with kinship, gender, and religion, Anderson argues in Imagined Communities for the irreducibility of material-cultural practices (what he memorably termed "print-capitalism") in creating and sustaining the "imagined community" of a nation whose citizens maintain "deep attachments" to each other in the absence of face-to-face contact: "the members of even the smallest nation will never know most of their fellow-members, meet them, or even hear of them, yet in the minds of each lives the image of their communion" [6]. Part of what makes such communities national, Anderson suggests, is a shared experience of simultaneity modeled on the spatio-temporal organization of newspapers and novels, for "these forms provided the technical means for 're-presenting' the kind of imagined community that is the nation" by furnishing their reader-consumers with a "complex gloss on the word 'meanwhile'" [25]. The "old-fashioned novel" especially, through its distinctive structures of address and omniscient point of view, becomes in this schema a "device" for generating a sociologically complex world populated by characters who, even though they "may be largely unaware of each other," nevertheless move together "calendrically through homogeneous, empty time"--a world, in short, that may be considered "a precise analogue of the idea of the nation, which also is conceived as a solid community moving steadily up (or down) history" [25-26]. As Jonathan Culler aptly summarizes in his contribution to this issue, Anderson thus takes the novel to be "a precondition for the nation" [24], "a formal condition of imagining the nation--a structural condition of possibility" [37]. Such strong emphasis on the novel as "a force for imagining the communities that are nations" certainly helps to explain why Imagined Communities so swiftly and pervasively became doxa in literary study--even if, as Culler elaborates, some of Anderson's readers have mistaken his argument for a stronger if less defensible [End Page 40] version that sees the novel as "a force in shaping or legitimating the nation" [37].While Anderson's analogy between novel and nation has been put by literary critics to a multitude of creative uses, what has been acknowledged much less commonly is that his literary interests are by no means exhausted by the paradigm for which he is best known. 1 The very title of his most recent book is, significantly as we shall see, a translated quotation from a novel, and he returns repeatedly for insights into the politics of literary form not only to Walter Benjamin but to certain exemplary "nationalist" novelists, José Rizal and Pramoedya Ananta Toer first and foremost. Where The Spectre of Comparisons is unusual in containing chapter-length readings of literary works (several of them reprinted from the earlier Language and Power), Imagined Communities was no stranger to detailed discussions of fiction. We may be struck, in fact, by the extent to which Anderson's theoretical and historical studies locate themselves persistently over time with reference to "literature... (shrink)

An alarming number of philosophers and cognitive scientists have argued that mind extends beyond the brain and body. This book evaluates these arguments and suggests that, typically, it does not. A timely and relevant study that exposes the need to develop a more sophisticated theory of cognition, while pointing to a bold new direction in exploring the nature of cognition Articulates and defends the “mark of the cognitive”, a common sense theory used to distinguish between cognitive and non-cognitive processes Challenges (...) the current popularity of extended cognition theory through critical analysis and by pointing out fallacies and shortcoming in the literature Stimulates discussions that will advance debate about the nature of cognition in the cognitive sciences.

One of liberalism’s core commitments is to safeguarding individuals’ autonomy. And a central aspect of liberal social justice is the commitment to protecting the vulnerable. Taken together, and combined with an understanding of autonomy as an acquired set of capacities to lead one’s own life, these commitments suggest that liberal societies should be especially concerned to address vulnerabilities of individuals regarding the development and maintenance of their autonomy. In this chapter, we develop an account of what it would mean for (...) a society to take seriously the obligation to reduce individuals’ autonomy-related vulnerabilities to an acceptable minimum. In particular, we argue that standard liberal accounts underestimate the scope of this obligation because they fail to appreciate various threats to autonomy. (shrink)

In his previous book, Being Upright: Zen Meditation and the Bodhisattva Precepts, Reb Anderson Roshi described how we must become thoroughly grounded in conventional truth through the practice of compassion before we can receive the teachings of the ultimate truth. In The Third Turning of the Wheel, he introduces us to the next stage of our journey by invoking the wisdom of the Samdhinirmocana Sutra. According to Anderson, the main purpose behind this enigmatic sutra is to reconcile the (...) apparent contradictions between the original teachings of the historical Buddha and the later teachings of Mahayana Buddhism. Anderson reflects on the great metaphysical questions proposed in the Samdhinirmocana Sutra-the nature of ultimate reality, the structure of human consciousness, the characteristics of phenomena, the stages of meditation, and the essential qualities of a buddha-with the clarity of a scholar and the insight of a practitioner.

This paper presents the outlines of a phenomenological theory of foundational or non-inferential knowledge according to which the facts or states of affairs towards which our beliefs are intentionally directed can sometimes serve as reasons or evidence for what we believe. This occurs in acts of fulfillment, in which an object or state of affairs is given as it is thought to be. Hopp further argues that the sorts of empirical facts that can serve as reasons for noninferentially justified beliefs (...) are not confined to facts about one’s own occurrent mental states, but include facts about the physical world as well. In the course of defending the view against objections, Hopp argues that we should be internalists about the reasons in virtue of which what we believe is justified but externalists about the factors in virtue of which our states of believing have the status of being justified. He also argues against the claim that mental states, such as perceptual experiences, constitute our evidence for empirical beliefs. (shrink)
