This paper has two goals. First, we develop frameworks for logical systems which are able to reflect not only non-monotonic patterns of reasoning, but also paraconsistent reasoning. Our second goal is to have a better understanding of the conditions that a useful relation for nonmonotonic reasoning should satisfy. For this we consider a sequence of generalizations of the pioneering works of Gabbay, Kraus, Lehmann, Magidor and Makinson. These generalizations allow the use of monotonic nonclassical logics as the underlying logic upon (...) which nonmonotonic reasoning may be based. Our sequence of frameworks culminates in what we call plausible, nonmonotonic, multiple-conclusion consequences relations . Our study yields intuitive justifications for conditions that have been proposed in previous frameworks and also clarifies the connections among some of these systems. In addition, we present a general method for constructing plausible nonmonotonic relations. This method is based on a multiple-valued semantics, and on Shoham's idea of preferential models. (shrink)

This work focuses on the conception of God of the medieval Jewish philosopher and legal scholar, Hasdai Crescas (1340-1410/11). It demonstrates that Crescas’ God is infinitely creative and good and explores the parallel that Crescas implicitly draws between God as creator and legislator.

The notion of bilattice was introduced by Ginsberg, and further examined by Fitting, as a general framework for many applications. In the present paper we develop proof systems, which correspond to bilattices in an essential way. For this goal we introduce the notion of logical bilattices. We also show how they can be used for efficient inferences from possibly inconsistent data. For this we incorporate certain ideas of Kifer and Lozinskii, which happen to suit well the context of our work. (...) The outcome are paraconsistent logics with a lot of desirable properties.1.

Constructions of Intersubjectivity shows that the meaning of grammatical constructions often has more to do with the human cognitive capacity for taking other peoples' points of view than with describing the world. Treating pragmatics, semantics, and syntax in parallel and integrating insights from linguistics, psychology, and animal communication, Arie Verhagen develops a new understanding of linguistic communication. In doing so he shows the continuity between language and animal communication and reveals the nature of human linguistic specialization. Professor Verhagen uses Dutch (...) and English data from a wide variety of sources and considers the contributions of grammar to the coherence of discourse. He argues that important problems in semantics and syntax may be resolved if language is understood as an instrument for exerting influence and coordinating different perspectives. The grammatical phenomena he discusses include negative expressions, the let alone construction, complementation constructions, and discourse connectives.This powerfully argued and original explanation of the nature and operation of communication will interest a wide range of scholars and advanced students in linguistics, cognitive science, and human evolution.

Longer-term developments shape the present and endogenous futures of institutions and practices of science and technology in society and their governance. Understanding the patterns allows diagnosis and soft intervention, often linked to scenario exercises. The book collects six articles offering key examples of this perspective, addressing ongoing issues in the governance of science and technology, including nanotechnology and responsible research and innovation. And adds two more articles that address background philosophical issues.

Some people claim that evolution is "just a theory". Do you know what a scientific theory really is? Just a theory is an overview of the modern concepts of science. A clear understanding of the nature of science will enable you to distinguish science from pseudoscience (which illegitimately wraps itself in the mantle of science), and real social issues in science from the caricatures portrayed in postmodernist critiques. Prof. Ben-Ari's style is light (even humorous) and easy to read, bringing the (...) latest concepts of science to the general reader. Of particular interest is his analysis of the terminology of science (fact, law, proof, theory) in relation to the colloquial meaning of these terms. Between chapters are biographical vignettes of scientists — both familiar and unfamiliar — showing their common commitment to the enterprise of science, together with a diversity of backgrounds and personalities. This accessible, informative, and comprehensive work will give lay readers a good grasp of real science. (shrink)

The public sphere, be it the Greek agora or the New York Times op-ed page, is the realm of appearances - not citizenship. Its central event is spectacle - not dialogue. Public dialogue, the mantra of many intellectuals and political commentators, is but a contradiction in terms. Marked by an asymmetry between the few who act and the many who watch, the public sphere can undermine liberal democracy, law, and morality. Inauthenticity, superficiality, and objectification are the very essence of the (...) public sphere. But the public sphere also liberates us from the bondages of private life and fosters an existentially vital aesthetic experience. Reign of Appearances uses a variety of cases to reveal the logic of the public sphere, including homosexuality in Victorian England, the 2008 crash, antisemitism in Europe, confidence in American presidents, communications in social media, special prosecutor investigations, the visibility of African-Americans, violence during the French Revolution, the Islamic veil, and contemporary sexual politics. This unconventional account of the public sphere is critical reading for anyone who wants to understand the effects of visibility in urban life, politics, and the media. (shrink)

An ℵ1-Souslin tree is a complicated combinatorial object whose existence cannot be decided on the grounds of ZFC alone. But fifteen years after Tennenbaum and Jech independently devised notions of forcing for introducing such a tree, Shelah proved that already the simplest forcing notion—Cohen forcing—adds an ℵ1-Souslin tree. In this article, we identify a rather large class of notions of forcing that, assuming a GCH-type hypothesis, add a λ+-Souslin tree. This class includes Prikry, Magidor, and Radin forcing.

In Part I of this series, we presented the microscopic approach to Souslin-tree constructions, and argued that all known ⋄-based constructions of Souslin trees with various additional properties may be rendered as applications of our approach. In this paper, we show that constructions following the same approach may be carried out even in the absence of ⋄. In particular, we obtain a new weak sufficient condition for the existence of Souslin trees at the level of a strongly inaccessible cardinal. We (...) also present a new construction of a Souslin tree with an ascent path, thereby increasing the consistency strength of such a tree's nonexistence from a Mahlo cardinal to a weakly compact cardinal. Section 2 of this paper is targeted at newcomers with minimal background. It offers a comprehensive exposition of the subject of constructing Souslin trees and the challenges involved. (shrink)

Within the space of a few years, the idea of Responsible Research and Innovation, and its acronym RRI, catapulted from an obscure phrase to the topic of conferences and attempts to specify and realize it. How did this come about, and against which backdrop? What are the dynamics at present, and what do these imply for the future of RRI as a discourse, and as a patchwork of practices? It is a social innovation which creates opening in existing divisions of (...) moral labour, a notion that is explained with the help of the history of responsibility language. It is filled in for the present situation and ongoing developments. Some elements may stabilize and this creates a path into the future. There will be reductions of the originally open-ended innovation, some productive, others less so. This is a reason to regularly inquire into the value of the reductions and the directions the path is taking. (shrink)

The transcriptional profile of the entire Caulobacter crescentus genome over a synchronous cell cycle was recently described.(1) The analysis reveals a stunning 553 cell-cycle-regulated genes or orfs, nearly 19% of the genome, including putative functions in virtually all biological activities. Over a quarter of these genes/orfs respond to the Caulobacter master regulator, CtrA, most of them apparently indirectly. The analysis confirms and extends earlier observations showing that many proteins involved in cell cycle functions are expressed at the cell age when (...) they are needed. Conversely, the data suggest that proteins specifically expressed at a particular age may be involved in a process taking place then. BioEssays 23:563–565, 2001. © 2001 John Wiley & Sons, Inc.

This study offers a fresh reappraisal of the philosopher, political thinker, and historian of ideas Sir Isaiah Berlin (1909-1997) from childhood to the height of his intellectual career. It provides the first historically contextualized study of Berlin's formative years and identifies different stages in his intellectual development, allowing a reappraisal of his theory of liberalism. Applying a 'double perspective' that examines Berlin both as an East European Jewish émigré; as well as a British Liberal intellectual, author Arie Dubnov stresses the (...) very ambivalent relation between Berlin's liberal philosophy and his pro-Zionist sentiments.

Ariès traces Western man's attitudes toward mortality from the early medieval conception of death as the familiar collective destiny of the human race to the modern tendency, so pronounced in industrial societies, to hide death as if it were an embarrassing family secret.

Paradefinite logics are logics that can be used for handling contradictory or partial information. As such, paradefinite logics should be both paraconsistent and paracomplete. In this paper we consider the simplest semantic framework for introducing paradefinite logics. It consists of the four-valued matrices that expand the minimal matrix which is characteristic for first degree entailments: Dunn–Belnap matrix. We survey and study the expressive power and proof theory of the most important logics that can be developed in this framework.

The article revisits the large n problem as it relates to the Jeffreys-Lindley paradox to compare the frequentist, Bayesian, and likelihoodist approaches to inference and evidence. It is argued that what is fallacious is to interpret a rejection of as providing the same evidence for a particular alternative, irrespective of n; this is an example of the fallacy of rejection. Moreover, the Bayesian and likelihoodist approaches are shown to be susceptible to the fallacy of acceptance. The key difference is that (...) in frequentist testing the severity evaluation circumvents both fallacies but no such principled remedy exists for the other approaches. (shrink)

We define in precise terms the basic properties that an ‘ideal propositional paraconsistent logic’ is expected to have, and investigate the relations between them. This leads to a precise characterization of ideal propositional paraconsistent logics. We show that every three-valued paraconsistent logic which is contained in classical logic, and has a proper implication connective, is ideal. Then we show that for every n > 2 there exists an extensive family of ideal n -valued logics, each one of which is not (...) equivalent to any k -valued logic with k < n. (shrink)

Many believe that the ethical problems of donation after cardiocirculatory death (DCD) have been "worked out" and that it is unclear why DCD should be resisted. In this paper we will argue that DCD donors may not yet be dead, and therefore that organ donation during DCD may violate the dead donor rule. We first present a description of the process of DCD and the standard ethical rationale for the practice. We then present our concerns with DCD, including the following: (...) irreversibility of absent circulation has not occurred and the many attempts to claim it has have all failed; conflicts of interest at all steps in the DCD process, including the decision to withdraw life support before DCD, are simply unavoidable; potentially harmful premortem interventions to preserve organ utility are not justifiable, even with the help of the principle of double effect; claims that DCD conforms with the intent of the law and current accepted medical standards are misleading and inaccurate; and consensus statements by respected medical groups do not change these arguments due to their low quality including being plagued by conflict of interest. Moreover, some arguments in favor of DCD, while likely true, are "straw-man arguments," such as the great benefit of organ donation. The truth is that honesty and trustworthiness require that we face these problems instead of avoiding them. We believe that DCD is not ethically allowable because it abandons the dead donor rule, has unavoidable conflicts of interests, and implements premortem interventions which can hasten death. These important points have not been, but need to be fully disclosed to the public and incorporated into fully informed consent. These are tall orders, and require open public debate. Until this debate occurs, we call for a moratorium on the practice of DCD. (shrink)

In recent years, the educational-system development specialization of the MA program in the University of Haifa’s Faculty of Education has held an annual seminar on Philosophy for/with Children (P4wC). Under my guidance, Jewish, Muslim, Christian, Druze, and Circassian students have formed a group embodying a living and breathing dialogical space. Despite the global spread of P4wC principles following the emergence of the P4C movement promoted by the International Council of Philosophical Inquiry and its practice in dozens of national and regional (...) centers, neither approach is formally taught in Israeli universities and colleges. Both thus remain outside the pedagogical mainstream, the University of Haifa—where I teach—being the only institution at which they can be studied at an MA level. I have also established the Israeli Academic Forum for Philosophy with Children, which conducts seminars and offers professional development, etc. (shrink)

This remarkable book--the fruit of almost two decades of study--traces in compelling fashion the changes in Western attitudes toward death and dying from the earliest Christian times to the present day. A truly landmark study, The Hour of Our Death reveals a pattern of gradually developing evolutionary stages in our perceptions of life in relation to death, each stage representing a virtual redefinition of human nature. Starting at the very foundations of Western culture, the eminent historian Phillipe Aries shows how, (...) from Graeco-Roman times through the first ten centuries of the Common Era, death was too common to be frightening; each life was quietly subordinated to the community, which paid its respects and then moved on. Aries identifies the first major shift in attitude with the turn of the eleventh century when a sense of individuality began to rise and with it, profound consequences: death no longer meant merely the weakening of community, but rather the destruction of self. Hence the growing fear of the afterlife, new conceptions of the Last Judgment, and the first attempts (by Masses and other rituals) to guarantee a better life in the next world. In the 1500s attention shifted from the demise of the self to that of the loved one (as family supplants community), and by the nineteenth century death comes to be viewed as simply a staging post toward reunion in the hereafter. Finally, Aries shows why death has become such an unendurable truth in our own century--how it has been nearly banished from our daily lives--and points out what may be done to "re-tame" this secret terror. The richness of Aries's source material and investigative work is breathtaking. While exploring everything from churches, religious rituals, and graveyards (with their often macabre headstones and monuments), to wills and testaments, love letters, literature, paintings, diaries, town plans, crime and sanitation reports, and grave robbing complaints, Aries ranges across Europe to Russia on the one hand and to England and America on the other. As he sorts out the tangled mysteries of our accumulated terrors and beliefs, we come to understand the history--indeed the pathology--of our intellectual and psychological tensions in the face of death.

We introduce a general approach for representing and reasoning with argumentation-based systems. In our framework arguments are represented by Gentzen-style sequents, attacks between arguments are represented by sequent elimination rules, and deductions are made according to Dung-style skeptical or credulous semantics. This framework accommodates different languages and logics in which arguments may be represented, allows for a flexible and simple way of expressing and identifying arguments, supports a variety of attack relations, and is faithful to standard methods of drawing conclusions (...) by argumentation frameworks. Altogether, we show that argumentation theory may benefit from incorporating proof theoretical techniques and that different non-classical formalisms may be used for backing up intended argumentation semantics.

Maximality is a desirable property of paraconsistent logics, motivated by the aspiration to tolerate inconsistencies, but at the same time retain from classical logic as much as possible. In this paper we introduce the strongest possible notion of maximal paraconsistency, and investigate it in the context of logics that are based on deterministic or non-deterministic three-valued matrices. We show that all reasonable paraconsistent logics based on three-valued deterministic matrices are maximal in our strong sense. This applies to practically all three-valued (...) paraconsistent logics that have been considered in the literature, including a large family of logics which were developed by da Costa's school. Then we show that in contrast, paraconsistent logics based on three-valued properly nondeterministic matrices are not maximal, except for a few special cases (which are fully characterized). However, these non-deterministic matrices are useful for representing in a clear and concise way the vast variety of the (deterministic) three-valued maximally paraconsistent matrices. The corresponding weaker notion of maximality, called premaximal paraconsistency, captures the "core" of maximal paraconsistency of all possible paraconsistent determinizations of a non-deterministic matrix, thus representing what is really essential for their maximal paraconsistency.

Hayek’s The Road to Serfdom has been interpreted as a general warning against state intervention in the economy.1 We review this argument in conjunction with Hayek’s later work and discern an institutional thesis about which forms of state intervention and economic institutions could threaten personal and political freedom. Economic institutions pose a threat if they allow for coercive interventions, as described by Hayek in The Constitution of Liberty: by giving someone the power to force others to serve one’s will by (...) threatening to inflict harm, in the absence of general rules of conduct. According to the logic of the argument, welfare-state provisions are not coercive insofar as they do not allow the identification and discriminatory treatment of individuals. By contrast, we claim that a structure of coercion is likely to emerge from the command-and-control nature of protectionist institutions and immigration restrictions currently advocated by the radical right.

Starting from common-sense notions of ‘furniture of the world’ a process ontology is developed in which prospective is an integral part. Technology as configurations that work (precariously) embodies expectations which structure further development. Examples (a cloned puppy, hotel keys, DC airplanes, stem cells, and overpasses on Long Island) are used to develop the notion of material narratives that are “written”, not just by engineers and designers/producers, but also by users: “reading” implies some further “writing”. In contrast to prevailing notions of (...) technological control (through manipulation of building blocks), the “writing” of nanotechnology is modulation of the invisible and impredictable - an extreme example of unruly technology and repair work after the fact, where in practice control is a gesture not so different from magic. Because ontology cannot be other than prospective, it is political throughout. Thus, prospective technology highlights ontological politics. (shrink)

Brain death has been accepted worldwide medically and legally as the biological state of death of the organism. Nevertheless, the literature has described persistent problems with this acceptance ever since brain death was described. Many of these problems are not widely known or properly understood by much of the medical community. Here we aim to clarify these issues, based on the two intractable problems in the brain death debates. First, the metaphysical problem: there is no reason that withstands critical scrutiny (...) to believe that BD is the state of biological death of the human organism. Second, the epistemic problem: there is no way currently to diagnose the state of BD, the irreversible loss of all brain functions, using clinical tests and ancillary tests, given potential confounders to testing. We discuss these problems and their main objections and conclude that these problems are intractable in that there has been no acceptable solution offered other than bare assertions of an ‘operational definition’ of death. We present possible ways to move forward that accept both the metaphysical problem - that BD is not biological death of the human organism - and the epistemic problem - that as currently diagnosed, BD is a devastating neurological state where recovery of sentience is very unlikely, but not a confirmed state of irreversible loss of all [critical] brain functions. We argue that the best solution is to abandon the dead donor rule, thus allowing vital organ donation from patients currently diagnosed as BD, assuming appropriate changes are made to the consent process and to laws about killing.

The Vatican recently published directives regarding “beginning of life” issues that explain the Catholic Church's position regarding new technologies in this area. We think that it is important to develop a response that presents the traditional Orthodox Jewish position on these same issues in order to present an alternative, parallel system. There are many points of commonality between the Vatican document and traditional Jewish thought as well as several important issues where there is a divergence of opinion. The latter include (...) the status of the zygote as produced during in vitro fertilization, the acceptable of procreation in a method other than through the conjugal act, and the permissibility of deriving benefit from the products of an illicit act. These points of agreement and disagreement are discussed in detail in this article. (shrink)

A recent commentary defends 1) the concept of 'brain arrest' to explain what brain death is, and 2) the concept that death occurs at 2–5 minutes after absent circulation. I suggest that both these claims are flawed. Brain arrest is said to threaten life, and lead to death by causing a secondary respiratory then cardiac arrest. It is further claimed that ventilation only interrupts this way that brain arrest leads to death. These statements imply that brain arrest is not death (...) itself. Brain death is a devastating state that leads to death when intensive care, which replaces some of the brain's vital functions such as breathing, is withdrawn and circulation stops resulting in irreversible loss of integration of the organism. Circulatory death is said to occur at 2–5 minutes after absent circulation because, in the context of DCD, the intent is to not attempt reversal of the absent circulation. No defense of this weak construal of irreversible loss of circulation is given. This means that paents in identical physiologic states are dead (in the DCD context) or alive (in the resuscitation context); the current state of death (at 2–5 minutes) is contingent on a future event (whether there will be resuscitation) suggesting backward causation; and the commonly used meaning of irreversible as 'not capable of being reversed' is abandoned. The literature supporting the claim that autoresuscitation does not occur in the context of no cardiopulmonary resuscitation is shown to be very limited. Several cases of autoresuscitation are summarized, suggesting that the claim that these cases are not applicable to the current debate may be premature. I suggest that brain dead and DCD donors are not dead; whether organs can be harvested before death from these patients whose prognosis is death should be debated urgently. (shrink)

Three-time New York Times bestselling author Dan Ariely teams up with legendary The New Yorker cartoonist William Haefeli to present an expanded, illustrated collection of his immensely popularWall Street Journal advice column, “Ask Ariely”. Behavioral economist Dan Ariely revolutionized the way we think about ourselves, our minds, and our actions in his books Predictably Irrational, The Upside of Irrationality, and The Honest Truth about Dishonesty. Ariely applies this scientific analysis of the human condition in his “Ask Ariely” Q & A (...) column in the Wall Street Journal, in which he responds to readers who write in with personal conundrums ranging from the serious to the curious: What can you do to stay calm when you’re playing the volatile stock market? What’s the best way to get someone to stop smoking? How can you maximize the return on your investment at an all-you-can-eat buffet? Is it possible to put a price on the human soul? Can you ever rationally justify spending thousands of dollars on a Rolex? In Ask Ariely, a broad variety of economic, ethical, and emotional dilemmas are explored and addressed through text and images. Using their trademark insight and wit, Ariely and Haefeli help us reflect on how we can reason our way through external and internal challenges. Readers will laugh, learn, and most importantly gain a new perspective on how to deal with the inevitable problems that plague our daily life. (shrink)

This article calls into question the charge that frequentist testing is susceptible to the base-rate fallacy. It is argued that the apparent similarity between examples like the Harvard Medical School test and frequentist testing is highly misleading. A closer scrutiny reveals that such examples have none of the basic features of a proper frequentist test, such as legitimate data, hypotheses, test statistics, and sampling distributions. Indeed, the relevant error probabilities are replaced with the false positive/negative rates that constitute deductive calculations (...) based on known probabilities among events. As a result, the ampliative dimension of frequentist induction—learning from data about the underlying data-generating mechanism—is missing. *Received August 2009; revised January 2010. †To contact the author, please write to: Department of Economics, Virginia Tech, Blacksburg, VA 24061; e-mail: aris@vt.edu.

This discussion note offers a preliminary analysis of what recent developments in human germline gene editing tell us about the effectiveness of speculative and anticipatory modes of techno-ethics. It argues that the benefits of speculative discussions are difficult to detect thus far, and that pushing the focal point of ethical discourse well ahead of the current state of technology may prematurely undermine existing norms long before a broad consensus would justify moving beyond them.

This paper first develops a theoretically motivated view of narrative as a special form of inferential, cooperative human communication, of the role that the past tense plays in the intersubjective coordination of narrators and readers, viz. that of ‘curtailing’ the immediate argumentative applicability of the represented situation, and of its relation to viewpoint management. In three case studies, it is subsequently shown how this helps to elucidate certain effects of present and past tense alternations in stories. While these effects are (...) multi-faceted and highly text-specific, there is a common denominator of the use of the past tense in the dimension of narrator-reader communication in the narratives. The analysis supports an independently motivated conception of intersubjectivity that assigns a special status to ‘coordination with other minds’, apart from senders and addressees. (shrink)
