This paper is an historical study of Tarski's methodology of deductive sciences (in which a logic S is identified with an operator Cn S, called the consequence operator, on a given set of expressions), from its appearance in 1930 to the end of the 1970s, focusing on the work done in the field by Roberto Magari, Piero Mangani and by some of their pupils between 1965 and 1974, and comparing it with the results achieved by Tarski and the Polish (...) school (Łoś, Suszko, Słupecki, Pogorzelski, Wójcicki). In the last section of the paper we will then compare these works with some recent developments in algebraic logic: this will lead to a better understanding of the results of the methodology of deductive science, but at the same time will show some intrinsic limits to such an approach to logic. Even if Magari's work on diagonizable algebras and universal algebra and Mangani's axiomatization of MV-algebras and results in model theory are rather famous, the articles on closure operators, published in the 1960s, are almost totally unknown outside Italy (mainly because of a linguistic limitation, the papers we analyse having been written and published in Italian). This paper aims to fill the gap in the literature and to enable the international community to get acquainted with this part of Italian logic. The same applies to some works published in Barcelona (in Catalan) at the end of the 1970s, analysed in the last section. (shrink)

This paper is a contribution to the reconstruction of Tarski’s semantic background in the light of the ideas of his master, Stanislaw Lesniewski. Although in his 1933 monograph Tarski credits Lesniewski with crucial negative results on the semantics of natural language, the conceptual relationship between the two logicians has never been investigated in a thorough manner. This paper shows that it was not Tarski, but Lesniewski who first avowed the impossibility of giving a satisfactory theory of truth for ordinary (...) language, and the necessity of sanitation of the latter for scientific purposes. In an early article (1913) Lesniewski gave an interesting solution to the Liar Paradox, which, although different from Tarski’s in detail, is nevertheless important to Tarski’s semantic background. To illustrate this I give an analysis of Lesniewski’s solution and of some related aspects of Lesniewski’s later thought. (shrink)

Recently, American Psychologist published a review of the evidence for parapsychology that supported the general claims of psi (the umbrella term often used for anomalous or paranormal phenomena). We present an opposing perspective and a broad-based critique of the entire parapsychology enterprise. Our position is straightforward. Claims made by parapsychologists cannot be true. The effects reported can have no ontological status; the data have no existential value. We examine a variety of reasons for this conclusion based on well-understood scientific principles. (...) In the classic English adynaton, “pigs cannot fly.” Hence, data that suggest that they can are necessarily flawed and result from weak methodology or improper data analyses or are Type I errors. So it must be with psi effects. What we find particularly intriguing is that, despite the existential impossibility of psi phenomena and the nearly 150 years of efforts during which there has been, literally, no progress, there are still scientists who continue to embrace the pursuit.

ArgumentThe present paper is an attempt to understand how medieval astronomers working within the Ptolemaic astronomical context in which the annular eclipse is an unjustified and impossible phenomenon, could know, define, justify, and later make attempts that led to success in predicting annular solar eclipses. As a context-based study, it reviews the situation of annular eclipses with regard to the medieval hypotheses applied to the calculation of the angular diameters of the sun and the moon, which was basic for contemplating (...) the possibility of annular eclipses. This gives the premises and the preliminary insights that were necessary to clarify the complex situation of the annular eclipse in the late medieval Islamic period and to explain the historical mechanisms leading to justifying the phenomenon during that period. This was, first due to a convincing and efficient observational evidence which, of course, was available only to a number of medieval astronomers and significantly for only a limited time period, and, second, the result of an amazing interaction amongst various astronomical traditions available to them. At a more general level, the research aims to inspect or, at least, to give some impressions of the essential conditions, i.e., identification of phenomenon, empirical evidence, and the justifying underlying tradition, under which it became possible in the tradition-based science of the `medieval period to permit a not-already-defined and tradition-opposed phenomenon to be posed and justified.

According to the Consequence Argument, the truth of determinism plus other plausible principles would yield the conclusion that we have no free will. In this paper I will argue that the conception of determinism typically employed in the various versions of the Consequence Argument is not plausible. In particular, I will argue that, taken most straightforwardly, determinism as defined in the Consequence Argument would imply that the existence of God is logically impossible. This is quite an implausible result. The (...) truth or falsity of determinism is typically taken to be a contingent, empirical matter. But how could the empirical discovery that determinism is true lead to the conclusion that God’s existence is a logical impossibility? The defender of the Consequence Argument can avoid this conclusion, but only at the cost of making other similarly implausible claims. The objection.. (shrink)

Arrow’s axiomatic foundation of social choice theory can be understood as an application of Tarski’s methodology of the deductive sciences—which is closely related to the latter’s foundational contribution to model theory. In this note we show in a model-theoretic framework how Arrow’s use of von Neumann and Morgenstern’s concept of winning coalitions allows to exploit the algebraic structures involved in preference aggregation; this approach entails an alternative indirect ultrafilter proof for Arrow’s dictatorship result. This link also connects Arrow’s seminal (...) result to key developments and concepts in the history of model theory, notably ultraproducts and preservation results. (shrink)

This article has three sections. The first discusses the problem of evil; the second, the sins of both angels and men that originally introduced evil into the world; the third, a teleological theory of evolution that clarifies the relationship between the first two sections. At present there is a great deal of discussion about the nature of the evolutionary process. Some argue that ultimately it is a strictly random one. But it is quite impossible to prove scientifically that evolution is (...) strictly random. From a Christian point of view the best way to view it is to see it not only as the result of divine intelligence, but also as due to a ferocious conflict between superhuman powers – the biblical angels and demons to whom God in the beginning gave the power to guide and develop his creation.

A new method was devised to test object permanence in young infants. Fivemonth-old infants were habituated to a screen that moved back and forth through a 180-degree arc, in the manner of a drawbridge. After infants reached habituation, a box was centered behind the screen. Infants were shown two test events: a possible event and an impossible event. In the possible event, the screen stopped when it reached the occluded box; in the impossible event, the screen moved through the space (...) occupied by the box. The results indicated that infants looked reliably longer at the impossible than at the possible event. This hnding suggested that infants (1) understood that the box continued to exist, in its same location, after it was occluded by the screen, and (2) expected the screen to stop against the occluded box and were surprised, or puzzled, when it failed to do so. A control experiment in which the box was placed next to the screen provided support for this interpretation of the results. Together, the results of these experiments indicate that, contrary to Piaget’s (1954) claims, infants as young as 5 months of age understand that objects continue to exist when occluded. The results, also indicate that 5-month-old infants realize that solid objects do not move through the space occupied by other solid objects. (shrink)

Organizational participants learn that "getting ahead" in organizational life comes from dramatizing a fantasy about the organization's perfection. The fantasy is the return to narcissism, in which the organization and its highest participants are seen as the center of a loving world. Since the return to narcissism is impossible, orienting the organization to the dramatization of this fantasy means that the organization loses touch with reality. The result is organizational decay-a condition of systemic ineffectiveness. Organizational decay is illustrated through (...) the case of General Motors. Specific dimensions considered are: commitment to bad decisions; advancement of participants who detach themselves from reality and discouragement of reality-oriented participants who are committed to their work; creation of the organizational jungle; isolation of management; development of a hostile orientation to the environment; transposition of work and ritual; loss of creativity; dominance of the financial staff; development of cynicism or the loss of reality; and overcentralizatior. Organizational decay may be compared with the consequences of hubris. (shrink)

Introduction Reza Davari Ardakni, the Iranian contemporary philosopher, distinguishes development from Western modernity; in that it considers modernity as natural and organic changes that Europe has gone through, but sees development as a planned design for implementing modernity in other countries. As a result, the closedness of development concerns only the developing countries, not Western modern ones. Davari emphasizes that the Western modernity has a universality that pertains to a unique reason and a unified world. The only way of (...) thinking in this world is a philosophical thought based on human self-centered reason, and given the pervasiveness of Western civilization. Therefore, Davari does not consider Westernization as mere imitation of Western customs and methods, but rather as a way of existence in the world. Westernization is a subjective view of the world and beings. Westernization is not optional, enabling non-Western people to avoid it. According to the Westernization scenario, the world today is entirely Westernized, and Davari considers Westernization as the inevitable fate of the people of this era, seeing two alternatives for them, both of which ultimately lead to the same destination, which is to embrace development; either they seize the power of science and technology and join the process of global modernization and participate in it, or they become subdued by this process and accept it without participation. Davari regards the first type of Westernization as active and the second type as passive. Problematique Therefore, underdevelopment is not a concept of the ancient world, nor even of a world between the ancient and the modern, or on the threshold of modernization. Underdevelopment is a condition of suspension and timelessness and being exposed to modernization. To escape the paradox of underdevelopment, which is the inevitable historical fate of non-modernized societies, Davari sees no way out other than embracing development. In other words, Westernized societies, which have become confused due to modernization, have no escape route other than turning to development. Therefore, some critics of Davari accuse the theory of Westernization of being a theoretical rupture. M. T. Tabatabaei, by rejecting the theoretical rupture in the theory of Westernization, believes that in the argument of Davari, we are only faced with a shift from a philosophical to an intellectual level. Tabatabaei, by avoiding providing a philosophical response to the critics of the theoretical rupture, believes that the introduction of active Westernization and collaboration in science and technology as a solution to escape from underdevelopment conditions, is only a shift from a philosophical level to an intellectual level and does not involve a rupture. Therefore, it seems that the philosophical issue of how or the possibility of escaping from underdevelopment conditions is still an open non answered problem. In this study, seeking a philosophical answer to this problem, an attempt has been made to summarize Davari's definitions of development, underdevelopment, participation in the world of science, and the role of humanities and social sciences in development, using his writings and speeches. It is proposed that a way to escape from the clesedness of development based on Davari's views, is to make use of analytical method with emphasizing on concepts and theories of the philosophy and metaphysics of science. Argument According to Davari, the social and human sciences that are responsible for development planning in underdeveloped societies must consider the characteristics of underdevelopment in order to facilitate the transition to more favorable conditions. Davari identifies the following conditions for successful development: 1) replacing tradition with science as the organizing and coordinating principle in society, 2) recognizing the universality of philosophy and science of the Western modernity and the impossibility of blindly imitation and adopting it, 3) inevitability of actively engaging and interacting with development, 4) recognizing the internal dynamics of scientific progress and avoiding authoritarian control, and 5) promoting free participation in the scientific paradigms. Therefore, Davari suggests the following steps towards development: 1) recognizing and understanding the problems of society and the local ecosystem, 2) understanding the philosophical and cultural foundations of Western civilization, 3) understanding the historical context and paradigms of science, 4) understanding the philosophical and metaphysical foundations of science, 5) recognizing the intellectual and philosophical capacities of our own community, and 6) reflecting our own philosophical and metaphysical assumptions in the scientific world in a way that is compatible with scientific methods. Given the motivations for change in science at both the global and national levels, including the emergence of heterodox or indigenous sciences, and the inevitable nature of development, Davari points to the possibility of a path between absolute rejecting or accepting the mainstream social and human sciences. However, this path is challenging and contingent upon the aforementioned conditions and steps of transition. Conclusion It is necessary to seek this path within the realm of the philosophy and metaphysics of science, particularly in the origins and foundations of the social and human sciences. Research in the metaphysics and philosophy of the social sciences provides the opportunity for active scientific engagement in the scientific paradigms and a reconsideration of the foundations of science, allowing for different philosophical foundations while are compatible with scientific methods. Successfully finding a path between absolute rejecting or accepting the existing social sciences will lead to an internal transformation within the field of science and, in fact, will advance the boundaries of knowledge. Therefore, it is possible, while adhering to the conditions of transition and actively participating in the world of science and technology, and accepting the unity of modernity and avoiding selectivity and imitation, to search for a way to overcome the closedness of development through a reconsideration of the philosophical and metaphysical foundations of science, while recognizing our own intellectual heritage and critically assessing Western science and technology.

This article gives a brief overview of Rethinking the Good, whose impossibility arguments illuminate the difficulty of arriving at a coherent theory of the good. I show that an additive-aggregationistprinciple is plausible for some comparisons, while an anti- additive-aggregationistprinciple is plausible for others. Invoking SpectrumArguments, I show that these principles are incompatible with an empirical premise, and various Axioms of Transitivity. I argue that whether the “all-things-considered better than” relation is transitive is not a matter of language or logic, (...) but the nature of moral ideals. If an Internal Aspects View holds, then many standard assumptions about rationality follow, including the Axioms of Transitivity, but not if an Essentially Comparative View holds. Yet many important ideals are essentially comparative. My results have important implications for the normative significance of economics, and require substantial revision in our understanding of the good, moral ideals, and the nature of practical reasoning.

This article discusses many issues raised by Munoz-Dardé, Katz, Ross, and Kagan. In doing this, I accept many of their claims, but reject others. I contend that the Essentially Comparative View can make genuine comparisons, deny that a contractualist approach helps with my book’s puzzles, and grant that my book’s central results are difficult to comprehend. I note important differences between economists’s impossibility results and my own, but accept that they may illuminate each other, using Sen’s Paradox of the (...) Paretian Liberal to illustrate this. I consider my work’s implications for the Sorites Paradox, as well as famous deontological cases. I also significantly reassess the Narrow Person-Affecting View, and some of my responses to Parfit and Broome. Finally, I stress my book’s many arguments challenging the Axioms of Transitivity, the high costs of retaining such axioms, and the importance of not prematurely choosing between highly plausible views that are inconsistent.

In lieu of an abstract, here is a brief excerpt of the content:From the Sacrifice of the Letter to the Voice of TestimonyGiorgio Agamben’s Fulfillment of MetaphysicsJeffrey S. Librett (bio)By denying us the limit of the Limitless, the death of God leads to an experience in which nothing may again announce the exteriority of being, and consequently to an experience which is interior and sovereign. But such an experience, for which the death of God is an explosive reality, discloses as (...) its own secret and clarification, its intrinsic finitude, the limitless reign of the Limit, and the emptiness of those excesses in which it spends itself and where it is found wanting.—Michel Foucault, “Preface to Transgression”Can there be a discourse that, without being a metalanguage or sinking into the unsayable, says language itself and exposes its limits?—Giorgio Agamben, “The Idea of Language”I shall not rest until every German sees that it is a shameful thing to be a lawyer.—Adolf Hitler, speech before theReichstag, April 26, 1942From his early works on, Giorgio Agamben has opposed the thought of no contemporary philosopher more consistently and programmatically than that of Jacques Derrida, whose questioning of phonocentric metaphysics Agamben has tried to replace by a characterization of metaphysics as (what I am calling here) graphocentric. To go back behind the replacement of the voice by the letter is for Agamben to recover the event of language itself, the taking-place of language as Being.1 In his conceptualization of the project for such a recovery, as we shall see, Agamben’s commitment to Heidegger’s fundamental ontology is overdetermined by his investment in the Christian God as logos.This philosophical program in Agamben’s early essays guides his later work on the homo sacer-sovereign relation but also distorts and disturbs the later work in three principal ways. First, it prompts him to propose an exclusively juridicopolitical understanding of the sacredness of the homo sacer, effectively scapegoating the juridical sphere for a more broadly theopolitical problem, while placing the specifically Christian background [End Page 11] of his antinomianism in a misleadingly secular, rational, and universalist light. Symptomatically, in order to accomplish this juridicopolitical reduction Agamben must reject Bataille’s analysis of sacrifice—along with the entire modern anthropological reading of the sacred—out of hand. For this rejection protects his discourse against any sustained confrontation with the importance of the sacrificial dimension for both what he calls the homo sacer and his own approach to law in his theorization of the homo sacer..Second, Agamben’s philosophical program impoverishes the account he provides of the Nazi death camps as an extreme example of the sovereign-homo sacer relation by making it impossible for him to appreciate the importance of Christian antinomianism in the formation of National Socialist ideology. For Agamben’s philosophical orientation requires or presupposes that he ignore or underestimate, first of all, the sacrificially anti-Semitic dimension of Christian antinomianism—the tendency of such antinomianism to make Judaism responsible for the ontological desert into which representation exiles us all. Further, as a consequence of his continuing commitment to this tradition, Agamben cannot see how important the tradition remains, even if in a displaced form, for Nazi anti-Semitism. I argue that Agamben’s animus against the letter blinds him to the Christian and sacrificial dimensions of the Holocaust—he ignores the former and explicitly, emphatically denies the latter dimension—because this animus represents his own commitment to the Christian antinomianism that, in its racialized National Socialist form, attempts to rid itself of the letter by sacrificing not only Judaism but the (biologically, racially construed) Jews. Because his radically antinomian program would become unsettled by his recognition of its important overlap with the ideological bases of National Socialism, Agamben cannot ultimately acknowledge the Christian and sacrificial aspects of the Holocaust.Finally, in Remnants of Auschwitz—his main reading (outside of Homo Sacer) of the significance of the Nazi death camps—Agamben positions “testimony” as the exemplary instance of the speaking of speech, the taking-place of language. The result of the destruction of European Jewry becomes here the revelation of poetic speech as a manifestation of the absolute. Unwittingly, Agamben ends up participating in... (shrink)

An uncertainty report describes the extent of an agent’s uncertainty about some matter. We identify two basic requirements for uncertainty reports, which we call faithfulness and completeness. We then discuss two pitfalls of uncertainty assessment that often result in reports that fail to meet these requirements. The first involves adopting a one-size-fits-all approach to the representation of uncertainty, while the second involves failing to take account of the risk of surprises. In connection with the latter, we respond to the (...) objection that it is impossible to account for the risk of genuine surprises. After outlining some steps that both scientists and the bodies who commission uncertainty assessments can take to help avoid these pitfalls, we explain why striving for faithfulness and completeness is important.

In his groundbreaking book, Against Coherence (2005), Erik Olsson presents an ingenious impossibility theorem that appears to show that there is no informative relationship between probabilistic measures of coherence and higher likelihood of truth. Although Olsson's result provides an important insight into probabilistic models of epistemological coherence, the scope of his negative result is more limited than generally appreciated. The key issue is the role conditional independence conditions play within the witness testimony model Olsson uses to establish (...) his result. Olsson maintains that his witness model yields charitable ceteris paribus conditions for any theory of probabilistic coherence. Not so. In fact, Olsson's model, like Bayesian witness models in general, selects a peculiar class of models that are in no way representative of the range of options available to coherence theorists. Recent positive results suggest that there is a way to develop a formal theory of coherence after all. Further, although Bayesian witness models are not conducive to the truth, they are conducive to reliability. (shrink)

Using these inverse limit reflection embeddings directly and by broadening the collection of U-representable sets, we prove structural results of L under the assumption that there exists an elementary embedding j : L → L. As a consequence we show the impossibility of a generalized inverse limit X-reflection result for X ⊆ Vλ+1, thus (...) focusing the study of L generalizations on L. (shrink)

In this article we challenge the notion that diversity serves as a good proxy for educational justice. First, we maintain that the story about how diversity might be accomplished and what it might do for students and society is internally inconsistent. Second, we argue that a disproportionate share of the benefits that might result from greater diversity often accrues to those already advantaged. Finally, we propose that many of the most promising and pragmatic remedies for educational injustice are often (...) rejected by liberal proponents of “diversity first” in favor of remedies that in most cases are practically impossible, and often problematic on their own terms. We argue that schools that are by geography and demography not ethnically or socioeconomically diverse still can successfully confront the obstacles that their students face in creating a life they have reason to value.

In lieu of an abstract, here is a brief excerpt of the content:Moral Distress: The Face of Workplace BullyingJohn S. MurrayAfter a 28–year long distinguished military career I accepted a research position in a tertiary academic health science center, which I considered to be my dream job following retirement. Initially I was to be responsible for one department. A second was added because of my expertise with disaster preparedness. Following my orientation, I immersed myself into my new roles recognizing that (...) there was much to be done to achieve the goal of getting both departmental research programs up to par with the rest of the organization. In a short time, I began to recognize one of my bosses was going to be challenging to work with.She expected that her name be included on all grant proposals and manuscripts despite making no substantial intellectual contributions to either. Additionally, she wanted unwarranted control over all research and scholarship activities I was engaged in with staff despite having no research experience. Even meeting with her to discuss my plans for the direction of research in this department, my efforts were met with argumentative and condescending behavior. She would agree to discuss my plans. When I showed up for meetings in her office she would get angry with me oftentimes for situations, which she herself created. I continued to move forward with my work feeling that how I had conducted research and scholarly work in the past, with integrity and uncompromising ethical standards, was going to be threatened. This created great moral stress for me. I felt overwhelmed, powerless and frustrated as a result of the uncertainty as to whether or not I could fulfill my responsibilities while still meeting moral obligations.Over time, my moral compass prevented me from deviating from the principles, which helped me to build a long–standing stellar reputation as a leader in the field of pediatric nursing. However, this came with a cost. Working for this particular boss was like being on an emotional rollercoaster. One day I would feel like she was pleased with my work, but the next day my efforts could be met with anger, demeaning and dismissive behaviors. Once she praised me in front of staff for the “great” work I was doing with the evidence–based practice initiative nurse leaders. The following day she reprimanded me for not working closely with this group. She was extremely well versed at singing my praises in front of staff. Behind her closed office door was a very different experience.I confided in some colleagues in this department how I was being treated. I quickly learned that all staff were treated in this manner by this one individual. They shared that condescending language and fear and intimidation were the norm. When [End Page 112] I asked them why no one had the awareness or courage to say this treatment was not right, they quickly shared with me that staff were deterred from speaking up for fear of greater bullying behaviors. Sadly, while everyone knew what was the right thing to do, institutional constraints made it nearly impossible to pursue the right course of action. It was readily apparent these nurses were missing advocacy. At that point, I decided it was important to seek a remedy to this problem recognizing it would be no easy task.Progressively, my work environment with this particular boss became intolerable. Despite working relentlessly to develop a research program, unwarranted criticism, unjustified blame, exclusion, isolation, unreasonable demands and denied opportunities persisted. By this time, I was suffering from nightmares, headaches, fear, anxiety, depression, difficulty concentrating, and problems with self–esteem. I felt like my professional competence and reputation was being unjustifiably denigrated by this one individual.In the past, I confided in trusted organizational leaders for guidance when faced with difficult situations. As such, I approached my other boss and shared what was happening. She was deeply concerned. She encouraged me to seek guidance from a safe and confidential environment where staff members can share concerns and receive assistance with how to handle these apprehensions. I had used a program like this in the past when dealing with moral distress. This experience was very helpful. In fact, I returned on multiple... (shrink)

In the course of his dispute with Conington on the comparative merits of Catullus and Horace, Munro taxed the Augustans with having made the lyric of the heart impossible in Latin by their virtual exclusion of diminutives from the language of poetry; and, whether that is the result or no, the general fact that diminutives are rare in the serious poetry of the Augustan age is well known. The details, however, are less easy to come by. Stolz and Stolz-Schmalz (...) devote a few unilluminating lines to the Stilistik of diminutives: otherwise the grammars and the treatises on diminutives known to me concern themselves only with forms and meanings. Except for a note by Professor Housman which, at 4. 927, sets out Manilius's diminutives, I know of no collections for any Augustan poet, and it is perhaps worth while therefore to state the facts. I have not indeed read through Augustan poetry for the purpose, but for some time past I have been in the habit of noting such diminutives as I have come across in the course of reading, and these lists I have now checked and amplified from the indexes to the authors concerned. My lists are probably not complete, but I hope they are sufficiently near it to present a true picture of the position. (shrink)

Spontaneous transitions between bound states of an atomic system, “Lamb Shift” of energy levels and many other phenomena in real nonrelativistic quantum systems are connected within the influence of the quantum vacuum fluctuations (fundamental environment (FE)) which are impossible to consider in the limits of standard quantum-mechanical approaches. The joint system “quantum system (QS) + FE” is described in the framework of the stochastic differential equation (SDE) of Langevin-Schrödinger (L-Sch) type, and is defined on the extended space R 3 ⊗ (...) R {ξ}, where R 3 and R {ξ} are the Euclidean and functional spaces, respectively. The density matrix for single QS in FE is defined. The entropy of QS entangled with FE is defined and investigated in detail. It is proved that as a result of interaction of QS with environment there arise structures of various topologies which are a new quantum property of the system. (shrink)

The way in which early followers of St. Thomas Aquinas interpreted or misinterpreted his metaphysical doctrines and works still needs much exploration, so a text edition and editor’s commentary of this kind is a most welcomed project, especially since Conrad of Prussia has possibly left us the earliest commentary on Aquinas’ De ente et essentia. The editing task is a precarious work, however, since Conrad’s commentary survives in only one known manuscript, located in the monastery library at Admont, Austria. The (...) editors’ printed result thus has a number of flaws, but without a copy of the codex it is impossible to say which derive from the manuscript and which from the editors. Without a text a reviewer cannot legitimately correct, but can only suggest alternatives to evident mistakes. In the first lectio there is a very humorous flaw. Conrad is trying to prove that little mistakes can sometimes lead to big ones. The edited text illustrates: "omnis canis creditur, celeste sydus est canis, ergo celeste sidus creditur. Interum: quidquid creditur, habet pedes; celeste sydus, ut dictum est, creditur; ergo habet pedes. Ecce quot inconvenientia sequuntur ex uno modico errore." Creditur makes no sense: "Every dog is believed."? Currit does make sense: "Every dog runs." Unwittingly the editors prove the point the author wanted to make. By misreading or failing to correct the fundamental word currit so frequently it grew into a big error. It grew into an even bigger one later because Professor Bobik’s commentary on this text is an explanation based on this faulty text. (shrink)

General regularities related toLagrangian andHamiltonian equations are revealed. Probability distributions for functions ofHamiltonian random variables are considered. It is shown that all probability distributions of this kind are fully determined by the probability distributions for the random variables satisfying the corresponding Lagrangian equations. Some formulas related tocanonically conjugate operators are given. The similarity of these formulas to those related to Hamiltonian random variables is demonstrated. The “quantum approach” to the treatment of Hamiltonian random variables is discussed, and the origin of (...) some peculiarities related to this approach is elucidated; it is explained, in particular, why it is impossible to form the joint probability density for canonically conjugate random variables when using this approach. The peculiarities revealed prove to be common for any objects possessing Hamiltonian random variables, irrespective of the nature of the objects, and coincide, therefore, with those in quantum mechanics. The existence of joint probability distributions for canonically conjugate random variables in the general case is demonstrated through the calculation of the corresponding joint mathematical expectations in an illustrative example. This proves, in particular, that joint probability distributions for canonically conjugate coordinates and momenta exist indeed in the case of mechanical microsystems. The results obtained prove once again that the pecularities of quantum mechanics are not related to the specificity of the measurements of physical quantities for microsystems. (shrink)

This study aimed to understand the expressions of fear in the journeys of health professionals who worked in the confrontation of coronavirus disease 2019 (COVID‐19), in the city of Manaus, in the Brazilian Western Amazon. This is an exploratory qualitative study that adopts interpretive description as a method to generate informed knowledge responsive to the needs of the practice. We included 56 participants, comprising 23 health managers and 33 health workers (middle and higher level) of different professional categories. The results (...) revealed three circles of experience: (1) knowledge and professional experience in dealing with the disease (unknown–known–experienced); (2) the growing proximity to death and loss (predicted–witnessed–suffered); and (3) the involvement and proximity to whatever affects the individual, their emotions, and personal transformations in the face of the threat (the collective, the neighbor, and oneself). Our results suggest that health professionals who worked during the COVID‐19 pandemic in Manaus experienced insecurity, dread, and fear, illustrating the complexity of developing their activities in the front line of care and management during the different phases of the pandemic. A contribution of the study is precisely that of capturing this complexity, which suggests the impossibility of analyzing fear only in its simple manifestation, or in each circle of experience.

Inclusivity is widely considered a requirement of defensible environmental risk consultations and is often either mandated or recommended to help ensure attention to stakeholders’ diverse views. Experience suggests the opposite: the emphasis on an inclusive consultation process often makes it impossible for decision makers to listen carefully to stakeholders and for citizens’ views to influence the design and choice of proposed actions. This paper briefly reviews the promise of environmental risk consultations before outlining several of the more serious problems associated (...) with an emphasis on inclusivity: long lists of undifferentiated concerns, facts tainted by stakeholders’ perspectives and worldviews, little access to clarifying dialogue or tests of expertise, few opportunities to scrutinize knowledge quality, avoidance of controversial issues, and an overwhelming abundance of information. As a result, the promotion of inclusivity often serves as a convenient excuse for decision makers to silence citizens by substituting quantity for quality, breadth for depth, and an adversarial approach for dialogue and informed understanding.

This paper demonstrates that the property of Replication Invariance, generally considered to be an innocuous requirement for the extension of fixed-population poverty comparisons to variable-population contexts, is incompatible with other plausible variable- and fixed-population axioms. This fact raises questions about what constitutes an appropriate headcount assessment of poverty, in terms of whether one should focus on the proportion, or the absolute numbers, of the population in poverty. This observation, in turn, has important implications for tracking poverty and setting targets for (...) its reduction or elimination. (shrink)

An argument against the use of non-medical egg freezing is that women should not use NMEF as it is an individualistic and morally problematic answer to the social problems that women face, for instance, in the labour market. Instead of allowing or expecting women to deal with these problems individually, we should address them by challenging the patriarchal structure of the labour market—for example, by securing equal pay and affordable childcare. In a recent article in Journal of Medical Ethics, I (...) argue that we should distinguish between different versions of this kind of reasoning and that all the versions discussed are implausible.1 In three separate comments following my article in the March 2021 issue of JME, Moen,2 Segers3 and Campo-Engelstein4 have supported and criticised some of my results. It is impossible, in such a short reply, to discuss all of their many relevant comments in detail, but in what follows I will reply to some of their criticism. Moen presents several interesting comments; let me try to deal with what I take to be the two most important ones. The first of these deals with some of my critical comments concerning …. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Evil in Modern Thought: An Alternative History of PhilosophyPaul S. MiklowitzSusan Neiman. Evil in Modern Thought: An Alternative History of Philosophy. Princeton: Princeton University Press, 2002. Pp. xii + 358. Cloth, $29.95.Contemporary philosophy in America tends to regard epistemological questions as the most fundamental of the discipline, but Susan Neiman's Evil in Modern Thought sets itself against this assumption in an attempt to sketch "an alternative history of (...) philosophy." "It's possible to begin to worry about the difference between appearance and reality because... a dream is so vivid that you want to grasp one of its objects for a moment or two of sleepy half-consciousness," Neiman writes, but then "you wake up in your bed, slap your face if you have to... " (5). The problem of evil, in stark contrast to such skeptical speculations, is far more urgent and trenchant; it is "the place where philosophy begins, and threatens to stop" (ibid.). Moreover, the problem of evil, far from being merely a theological quandary, actually forms a link between metaphysics and epistemology by starkly posing questions about the intelligibility of the world: Why are things like that? wants the answer Because it's best that way. For the early modern period, these questions centered on the "theodicy" debates focused by the catastrophic Lisbon earthquake of 1755, while for us the holocaust threatens to explode all our hopes and expectations for the possibility of a world that is as it should be. Thus, Lisbon and Auschwitz frame for Neiman the historical topoi that ground discussion of the relation between natural and moral evils, the evolving philosophical understanding of which defines "who we have become in the three centuries that separate us from the early Enlightenment" (10).The problem of theodicy is introduced through the figure of Alfonso X, king of Castille in 1252, and "the first Enlightenment hero" (14), according to Neiman. Having studied astronomy under the guidance of learned Jews from Toledo, Alfonso scandalously remarked "If I had been of God's counsel at the Creation, many things would have been ordered better" (15). Serving as a paradigm of blasphemy for half a millennium, Alfonso's boast also expresses the inevitable dismay that must accompany the delighted wonder at natural order exploited by the argument from design: while Creation is surely miraculous in its manifestation of seemingly intelligent structure, it is just as surely astonishing that so much of that structure seems so wantonly destructive. Can this really be the best of all possible worlds if innocent lives are cut short by cruel diseases or natural disasters while vicious villains prosper into comfortable old age?! Alfonso's remark serves Neiman as a leitmotif around which she orders central figures in the canon of western philosophy into two camps: those who struggled to reconcile natural evil with God's goodness or with reason (Leibniz, Pope, Rousseau, Kant, Hegel and Marx), and those who skeptically condemned reason by appealing to "brute appearances" (Bayle, Voltaire, Hume, Sade and Schopenhauer). Because the very categories of natural and moral evil tend to break down as a result of the development of psychology as a "science of nature" (to the extent that human motives are regarded as natural processes subject to empirical explanation, they cease to manifest a unique ontology), Nietzsche and Freud fall outside the philosophical canon thus construed—although Neiman's discussion of these two thinkers is perhaps the most compelling of the book.No new interpretive ground is broken in the resulting exegesis of western philosophical history, but Neiman's treatment of each of these figures is intelligent and skillful. In discussing Kant, for example, a deep paradox at the center of his moral thought is brilliantly harnessed to the book's argument. Whereas theodicies from Leibniz onward had focused on attempts to show that Providence ultimately guaranteed a connection between virtue and happiness despite obvious evidence to the contrary, Kant took exactly the opposite tack. As Neiman puts it, "Solving the problem of evil is not only impossible but immoral. For knowing the connections between moral and natural evils would undermine the possibility of morality" (69). If we could be sure that good deeds... (shrink)

This paper suggests an alternative reading of Practice in Christianity to Merold Westphal’s interpretation of the text as defining what he calls “religiousness C.” Attending closely to the rhetorical construction of Practice, and situating it in the context of Kierkegaard’s intensive reading of Luther late in his life, I argue that this text extends the Postscript’s meditation on inwardness and writing to one of the central theological constructs of Lutheranism, the distinction between law and gospel. On my reading, Practice both (...) defends the primacy of faith and grace within Christianity, and refuses their commodification into directly communicable results. At the end of this paper, I consider Kierkegaard’s seeming retraction, in 1855, of two rhetorical features of Practice that my reading emphasizes. Iconclude that this gesture in fact intensifies Kierkegaard’s appropriation of the law/gospel paradigm, and speaks to the impossibility of any direct, comprehensive, and final account of authentic Christian life.

The paper investigates the video game discourse of the Russian state media from 2011 to 2015. Critical discourse analysis serves as a methodological framework for this work, and Foucault’s power/knowledge model is used to explain the logic behind the «grotesque discourses». In the Russian press, video games are described as an instance of inculcation, provoking overintense emotions and forcing individuals to commit symbolic acts impossible from the standpoint of “normal” pedagogy. The paper problematizes the mythologization of violence in video games (...) and identifies the main tropes used to establish the connection between video games and violence (murders) as “natural” and “obvious”. Particular attention is paid to the publications of Aleksandr Minkin, a reporter at “Moskovskij Komsomolets” (“Moscow Komsomol Member”) and one of the most prominent critics of video games, as well as to the media coverage of the first school shooting in Russia (shooting at school № 263 in 2014). It is shown that video games are used in the media discourse as an explanatory principle that allows a shift from the crime to the criminal, to those acts which reveal moral depravity or psychological disorder, and those circumstances which foster criminalism. Pointing to the games helps restore the “normal” connection between social and moral qualities, explaining the crime committed by an honours student from a “good family” as being the result of the depictions of violence in video games affecting the child’s psyche. Video games are also described as a factor in shaping the “digital generation” or “generation of gamers” — odd and politically dangerous. The dangers that games create for both gamers and society in general (the non-distinction between the “real” and the “virtual”, the illusion of a “possible restart”) allow the journalists and experts to insist on strengthening measures of supervision and protection, and expanding legal and medical control.

Tarski's theorem essentially says that the Liar paradox is paradoxical in the minimal reflexive frame. We generalise this result to the Liar-like paradox $\lambda^\alpha$ for all ordinal $\alpha\geq 1$. The main result is that for any positive integer $n = 2^i(2j+1)$, the paradox $\lambda^n$ is paradoxical in a frame iff this frame contains at least a cycle the depth of which is not divisible by $2^{i+1}$; and for any ordinal $\alpha \geq \omega$, the paradox $\lambda^\alpha$ is paradoxical (...) in a frame iff this frame contains at least an infinite walk which has an arbitrarily large depth. We thus get that $\lambda^n$ has a degree of paradoxicality no more than $\lambda^m$ iff the multiplicity of 2 in the (unique) prime factorisation of $n$ is no more than that in the prime factorisation of $m$; and all tranfinite $\lambda^\alpha$ has the same degree of paradoxcality but has a higher degree of paradoxicality than any $\lambda^n$.

Expertise depends on hours and hours of practice within a field before a state of proficiency is achieved. Normally, expert skills involve bodily knowledge associated to the practices of a field. Interactional expertise, i.e. the ability to talk competently about the field, however, is not causally dependent on bodily proficiency. Instead, interactional experts are verbally skilled to an extent that makes them impossible to distinguish from so-called contributory experts, the experienced practitioners. The concept of interactional expertise defines linguistic skills as (...) contingent on bodily knowledge. However, recent neuropsychological findings make it plausible that “first-person”-related neural activations would be relevant with respect to the subjects' verbal output, at least when subjects address concepts that refer to tangible objects. Using imitation games, we explore and expand on the apparently arbitrary relation between bodily experiences and linguistic skills in midwifery. In alignment with several findings within grounded cognition studies, the results presented suggest that somehow personal experiences make a linguistic difference, noticeable to contributory experts.

_Tarski’s World_ is an innovative and exciting method of introducing students to the language of first-order logic. Using the courseware package, students quickly master the meanings of connectives and qualifiers and soon become fluent in the symbolic language at the core of modern logic. The program allows students to build three-dimensional worlds and then describe them in first-order logic. The program, compatible with Macintosh and PC formats, also contains a unique and effective corrective tool in the form of a game, (...) which methodically leads students back through their errors if they wrongly evaluate the sentences in the constructed worlds. A brand new feature in this revised and expanded edition is student access to Grade Grinder, an innovative Internet-based grading service that provides accurate and timely feedback to students whenever they need it. Students can submit solutions for the program’s more than 100 exercises to the Grade Grinder for assessment, and the results are returned quickly to the students and optionally to the teacher as well. A web-based interface also allows instructors to manage assignments and grades for their classes. Intended as a supplement to a standard logic text, _Tarski’s World_ is an essential tool for helping students learn the language of logic. (shrink)

According to influential accounts of scientific method, such as critical rationalism, scientific knowledge grows by repeatedly testing our best hypotheses. But despite the popularity of hypothesis tests in statistical inference and science in general, their philosophical foundations remain shaky. In particular, the interpretation of non-significant results—those that do not reject the tested hypothesis—poses a major philosophical challenge. To what extent do they corroborate the tested hypothesis, or provide a reason to accept it? Popper sought for measures of corroboration that could (...) adequately answer this question. According to Popper, corroboration is different from probability-raising, and grounded in the predictive success and testability of a hypothesis. As such, corroboration becomes an indicator of the scientific value of a hypothesis and guides our practical preferences over hypotheses that have been subjected to severe tests. This article proves two impossibility results for corroboration measures based on statistical relevance. The generality of these results shows that Popper’s qualitative characterization of corroboration must be misguided.

The extraction of a pecuniary penalty for the recusancy of married women was a heavily contested issue in the Parliament of Elizabeth. Under the rules of coverture, married women controlled no property. It was thus ineffective to fine them, for they were unable to pay the penalty. As a result, the government attempted to hold husbands responsible for the penalties of their wives through the use of recognizances under the auspices of the Commissions for Causes Ecclesiastical, a prerogative court. (...) Research into the York Commission’s use of recognizances indicated that it had indeed been possible legitimately and legally to obtain a pecuniary penalty for the recusancy of a married woman by the 1570s. This was generally believed to have been legally impossible until they became obtainable by statute in 1593. Detailed examination of the records of the Commission indicates clearly that the depiction in the scholarly literature of the levying of these penalties as somehow improper or even illegal is erroneous. These forfeitures might have seemed irregular, but were indeed legitimate and obtained by proper and legal means in the context of contemporary standards of authority and control, both governmental and familial. This study demonstrates how respect for the standards of coverture, patriarchy, and marital obligations incorporated in the use of the recognizance provided a highly effective and legal means to penalise and correct both recusant wives and their husbands.

Neuropsychological deficits have been widely used to elucidate normal cognitive functioning. Can patients with such deficits also be used to understand conscious visual experience? In this paper, we ask what it would be like to be a patient with apperceptive agnosia . Philosophical analyses of such questions have suggested that subjectively experiencing what another person experiences would be impossible. Although such roadblocks into the conscious experience of others exist, the experimental study of both patients and neurologically normal subjects can be (...) used to understand visual processing mechanisms. In order to understand the visual processes damaged in apperceptive agnosia, we first review this syndrome and present a case study of one such patient, patient J.W. We then review several theoretical accounts of apperceptive agnosia, and we conclude that studies of the patients themselves may not allow us to discriminate between the various explanations of the syndrome. To test these accounts, we have simulated apperceptive agnosia in neurologically normal subjects. The implications of our results for understanding both apperceptive agnosia and normal visual processing are discussed. (shrink)

Among the influential contributions of Alfred Tarski to logic and philosophy, and close in importance to his widely applied and discussed definition of truth, one finds his definition of logical consequence for formal languages. Like his definition of truth, Tarski's definition of logical consequence has been widely and fruitfully applied. Unlike the definition of truth, that of logical consequence has been rarely discussed philosophically. The main aim of this dissertation is to offer a thorough discussion of some philosophical issues (...) arising from the neglected definition. ;The point of departure is an interpretative reading of the relevant writings by Tarski. This reading yields historically interesting data that refute other recent readings. It also provides philosophical illumination, by clarifying how Tarski thought that his definition satisfied some pretheoretic desiderata. ;Next it is discussed whether Tarski's definition satisfies other pretheoretic desiderata, not stated by Tarski and in some cases not endorsed by him, but which are desiderata nonetheless from reasonable standpoints. These include the desiderata that all instances of logical consequence in Tarski's defined sense be instances of analytical implication, and that they be instances of valid implication. The conclusion of this part of the dissertation is that, under reasonable assumptions regarding the field of applicability of the definition and the concepts used in it, there are reasons to believe that these desiderata are met, and none to believe they are not. ;Finally, the problem of logical constants is examined. The concept of a "logical constant" is the only concept not taken from logic and mathematics that appears in Tarski's definition. The problem of logical constants is that of replacing the primitive 'logical constant' with a defined, better understood concept, and in a such a way that the resulting defined concept of logical consequence meets the previously discussed desiderata. The main conclusion of this part is that some attempts to do this replace the obscure with the more obscure, while other attempts that seem to be in the right spirit have shortcomings of their own.

We recall one Tarski's result about the existence of a non-zero additive measure defined on power set of an infinite set vanishing on finite subsets. This rather surprising result goes back to 1930 and it allows to introduce a non-trivial linear functional invariant under changes of finitely many inputs.

The new concept of lambda calculi with monotone inductive types is introduced byhelp of motivations drawn from Tarski's fixed-point theorem (in preorder theory) andinitial algebras and initial recursive algebras from category theory. They are intendedto serve as formalisms for studying iteration and primitive recursion ongeneral inductively given structures. Special accent is put on the behaviour ofthe rewrite rules motivated by the categorical approach, most notably on thequestion of strong normalization (i.e., the impossibility of an infinitesequence of successive rewrite (...) steps). It is shown that this key propertyhinges on the concrete formulation. The canonical system of monotone inductivetypes, where monotonicity is expressed by a monotonicity witness beinga term expressing monotonicity through its type, enjoys strong normalizationshown by an embedding into the traditional system of non-interleavingpositive inductive types which, however, has to be enriched by the parametricpolymorphism of system F. Restrictions to iteration on monotone inductive typesalready embed into system F alone, hence clearly displaying the differencebetween iteration and primitive recursion with respect to algorithms despitethe fact that, classically, recursion is only a concept derived from iteration.

Deflationsism about truth is a pot-pourri, variously claiming that truth is redundant, or is constituted by the totality of 'T-sentences', or is a purely logical device (required solely for disquotational purposes or for re-expressing finitarily infinite conjunctions and/or disjunctions). In 1980, Hartry Field proposed what might be called a 'deflationary theory of mathematics', in which it is alleged that all uses of mathematics within science are dispensable. Field's criterion for the dispensability of mathematics turns on a property of theories, called (...) conservativeness. I present some technical results, some of which may be found in Tarski (1936), concerning the logical properties of truth theories; in particular, concerning the conservativeness of adding a truth theory for an object level language to any theory expressed in it. It transpires that various deflationary truth theories behave somewhat differently from the standard Tarskian truth theory. These results suggest that Tarskian theories of truth are not redundant or dispensable. Finally, I hint at an analogy between the behaviour of mathematical theories and of standard (Tarskian) theories of truth with respect to their indispensability to, as Quine would put, our 'scientific world-view'.

It is shown that the axioms Cubitt and Sugden (1994; Economic J. 104: 798) impose on a theory of rationally justifiable play (TRJP) do not prevent the possibility that two players necessarily disagree concerning the probability they ascribe to the choice of a third player. This appears to indicate that those axioms are not sufficient for defining a `reasonable' TRJP. In addition, for the case in which a player's beliefs are statistically independent, conditions for a TRJP are suggested under which (...) the existence of a quasi-strict equilibrium is sufficient, but the existence of a consistent n-pair is not, for defining a TRJP meeting those requirements.

In his seminal work “The Concept of Truth in Formalized Languages”, Alfred Tarski showed how to construct a formally correct and materially adequate definition of true sentence for certain formalized languages. These results have, eventually, been accepted and applauded by philosophers and logicians nearly in unison. Its Postscript, written two years later, however, has given rise to a considerable amount of controversy. There is an ongoing debate on what Tarski really said in the postscript. These discussions often regard Tarski as (...) putatively changing his logical framework from type theory to set theory. In what follows, we will compare the original results with those presented two years later. After a brief outline of Carnap’s program in The Logical Syntax of Language we will determine its significance for Tarski’s final results. (shrink)

Metalogic is an open-ended cognitive, formal methodology pertaining to semantics and information processing. The language that mathematizes metalogic is known as metalanguage and deals with metafunctions purely by extension on patterns. A metalogical process involves an effective enrichment in knowledge as logical statements, and, since human cognition is an inherently logic–based representation of knowledge, a metalogical process will always be aimed at developing the scope of cognition by exploring possible cognitive implications reflected on successive levels of abstraction. Indeed, it is (...) basically impracticable to maintain logic–and–metalogic without paying heed to cognitive theorizing. For it is cognitively irrelevant whether possible conclusions are deduced from some premises before the premises are determined to be true or whether the premises themselves are determined to be true first and, then, the conclusions are deduced from them. In this paper we consider the term metalogic as inherently embodied under the framework referred to as cognitive science and mathematics. We propose a metalogical interpretation of Arrow’s impossibility theorem and, to that end, choice theory is understood as a mental course of action dealing with logic and metalogic issues, in which a possible mathematical approach to model a mental course of action is adopted as a systematic operating method. Nevertheless, if we look closely at the core of Arrow’s impossibility theorem in terms of metalogic, a second fundamental contribution to this framework is represented by the Nash equilibrium. As a result of the foregoing, therefore, we prove the metalogical equivalence between Arrow’s impossibility theorem and the existence of the Nash equilibrium. More specifically, Arrow’s requirements correspond to the Nash equilibrium for finite mixed strategies with no symmetry conditions. To demonstrate this proof, we first verify that Arrow’s set and Nash’s set are isomorphic to each other, both sets being under stated conditions of non–symmetry. Then, the proof is completed by virtue of category theory. Indeed, the two sets are categories that correspond biuniquely to one another and, thus, it is possible to define a covariant functor that preserves their mutual structures. According to this, we show the proof–dedicated metalanguage as a precursor to a special equivalence theorem. (shrink)

Arrow’s impossibility result not only had a profound influence on welfare economics, but was, as this paper shows, also widely discussed in philosophy of science and in the engineering design literature.

In his published work and even more in conversations, Tarski emphasized what he thought were important philosophical aspects of his work. The English translation of his more philosophical papers [56m] was dedicated to his teacher Tadeusz Kotarbinski, and in informal discussions of philosophy he often referred to the influence of Kotarbinski. Also, the influence of Leiniewski, his dissertation adviser, is evident in his early papers. Moreover, some of his important papers of the 1930s were initially given to philosophical audiences. For (...) example, the famous monograph on the concepotf truth ([33”], [35b]) was first given as twol ectures to the Logic Section of the Philosophical Society in Warsaw in 1930. Second, his paper [33], which introduced the concepts of co-consistency and co-completeness as well as the rule of infinite induction: was first given at the Second Conference of the Polish Philosophical Society in Warsaw in 1927. Also [35c] was based upon an address given in 1934 to the conference for the Unity of Science in Prague; C361 and [36a] summarize an address given at the International Congress of Scientific Philosophy in Paris in 1935. The article [44a] was published in a philosophical journal and widely reprinted in philosophical texts. This list is of course not exhaustiveb ut only representative of Tarski’s philosophical interactions as reflected in lectures given to philosophical audiences, which were later embodied in substantial papers. After 1945 almost all of Tarski’s publications and presentations are mathematical in character with one or two minor exceptions. This division, occurring about 1945, does not, however, indicate al oss of interest in philosophical questionbsu t is a result of Tarski’s moving to the Department of Mathematics at Berkeley. There he assumed an important role in the development of logic within mathematics in the United States. (shrink)

Suppose that the members of a group each hold a rational set of judgments on some interconnected questions, and imagine that the group itself has to form a collective, rational set of judgments on those questions. How should it go about dealing with this task? We argue that the question raised is subject to a difficulty that has recently been noticed in discussion of the doctrinal paradox in jurisprudence. And we show that there is a general impossibility theorem that (...) that difficulty illustrates. Our paper describes this impossibility result and provides an exploration of its significance. The result naturally invites comparison with Kenneth Arrow's famous theorem (Arrow, 1963 and 1984; Sen, 1970) and we elaborate that comparison in a companion paper (List and Pettit, 2002). The paper is in four sections. The first section documents the need for various groups to aggregate its members' judgments; the second presents the discursive paradox; the third gives an informal statement of the more general impossibility result; the formal proof is presented in an appendix. The fourth section, finally, discusses some escape routes from that impossibility. (shrink)
