Each annual Ontology Summit initiative makes a statement appropriate to each Summit’s theme as part of our general advocacy designed to bring ontology science and engineering into the mainstream. The theme this year is "Towards an Open Ontology Repository". This communiqué represents the joint position of those who were engaged in the year's summit discourse on an Open Ontology Repository (OOR) and of those who endorse below. In this discussion, we have agreed that an "ontology repository is a facility where (...) ontologies and related information artifacts can be stored, retrieved and managed." -/- We believe in the promise of semantic technologies based on logic, databases and the Semantic Web, a Web of exposed data and of interpretations of that data (i.e., of semantics), using common standards. Such technologies enable distinguishable, computable, reusable, and sharable meaning of Web and other artifacts, including data, documents, and services. We also believe that making that vision a reality requires additional supporting resources and these resources should be open, extensible, and provide common services over the ontologies. (shrink)

Der Sammelband vereint Beitrage, die dem Andenken an den Philosophiehistoriker Thomas Ricklin gewidmet sind und an dessen Arbeit anschlieaen. Die Texte befassen sich mit der Erforschung der Philosophie- und Kulturgeschichte des Mittelalters, der Renaissance und der Fruhen Neuzeit und bieten ein Panorama der verschiedenen Dimensionen dessen, was Weisheit und Philosophie in diesen Epochen bedeuteten. Im Zentrum stehen Dante und Boccaccio, wobei insbesondere deren Lehre vom "Schleier" der poetischen Sprache, unter dem die Wahrheit verhullt sei, in einer Reihe von Studien untersucht (...) wird. In diesem Kontext widmen sich weitere Beitrage den Konzepten einiger der wichtigsten Denker des Mittelalters, wie Boethius von Dacien, Roger Bacon, Johannes von Wales, Meister Eckhart und Pietro d'Abano, dessen "Differentia prima" hier zum ersten Mal in einer kritischen Edition vorgelegt wird. Auaerdem wird die Uberlieferung und Auslegung der antiken Exempla als viel zu lange vernachlassigter Teil der Philosophiegeschichte in den Fokus geruckt. Des Weiteren thematisieren die Beitrage Autoren und Texte, die philosophische Fragen verhandeln, ohne den paradigmatischen Formen des Kommentars oder der Summa zugerechnet werden zu konnen, weil sie Sprach- und Genregrenzen uberschreiten, wie Giordano da Pisa, Jodocus Eichmann und Henry More. Weitere Beitrage, die sich mit Philosophinnen und Historikerinnen der Renaissance und Fruhen Neuzeit beschaftigen, verschaffen den weiblichen Stimmen in von Mannern dominierten Diskursen Gehor.

A transcript of Leo Strauss’s key seminars on Plato’s Protagoras. This book offers a transcript of Strauss’s seminar on Plato’s Protagoras taught at the University of Chicago in the spring quarter of 1965, edited and introduced by renowned scholar Robert C. Bartlett. These lectures have several important features. Unlike his published writings, they are less dense and more conversational. Additionally, while Strauss regarded himself as a Platonist and published some work on Plato, he published little on individual dialogues. In these (...) lectures Strauss treats many of the great Platonic and Straussian themes: the difference between the Socratic political science or art and the Sophistic political science or art of Protagoras; the character and teachability of virtue, its relation to knowledge, and the relations among the virtues, courage, justice, moderation, and wisdom; the good and the pleasant; frankness and concealment; the role of myth; and the relation between freedom of thought and freedom of speech. In these lectures, Strauss examines Protagoras and the sophists, providing a detailed discussion of Protagoras as it relates to Plato’s other dialogues and the work of modern thinkers. This book should be of special interest to students both of Plato and of Strauss. (shrink)

Using state-of-the-art observational datasets and results from a large archive of computer model simulations, a consortium of scientists from 12 different institutions has resolved a long-standing conundrum in climate science—the apparent discrepancy between simulated and observed temperature trends in the tropics. Research published by this group indicates that there is no fundamental discrepancy between modeled and observed tropical temperature trends when one accounts for: the uncertainties in observations; and the statistical uncertainties in estimating trends from observations. These results refute a (...) recent claim that model and observed tropical temperature trends “disagree to a statistically significant extent”. This claim was based on the application of a flawed statistical test and the use of older observational datasets. (shrink)

Professor Eric A. Havelock in his book The Liberal Temper in Greek Politics approaches classical political philosophy from the positivistic point of view. The doctrine to which he adheres is however a somewhat obsolete version of positivism. Positivist study of society, as he understands it, is "descriptive" and opposed to "judgmental evaluation" but this does not prevent his siding with those who understand "History as Progress." The social scientist cannot speak of progress unless value judgments can be objective. The up-to-date (...) or consistent positivist will therefore refrain from speaking of progress and instead speak of change. Similarly Havelock appears to accept the distinction between primitive men or savages and civilized men, whereas the consistent positivist will speak not of savages but of pre-literate men and assert that preliterate men have "civilizations" or "cultures" neither superior nor inferior to those of literate men. It would be wrong to believe that the up-to-date positivist is entirely consistent or that his careful avoidance of "evaluative" terms is entirely due to his methodological puritanism; his heart tells him that once one admits the inequality of "cultures," one may not be able to condemn colonialism on moral grounds. Havelock is therefore perhaps only more intelligent or more frank than the consistent positivists when he describes his position as liberal rather than as positivist. Yet this does not entirely dispose of the difficulty. "For the liberals man is to be taken as you find him and therefore his present political institutions are to be taken as given also." This means that here and now the liberals will take American democracy as given and will then "concentrate empirically and descriptively on this kind of political mechanism." This is a fair description of positivistic political science at its best. Yet Havelock praises the same liberals for writing "in defence of democracy". What then is a liberal? Was a German social scientist who in 1939 took "the present political institutions as given" and subjected them to "empirical analysis" for this reason by itself a liberal? If so then a liberal is not a man of strong moral or political convictions, and this does not seem to agree with the common meaning of the word. Yet from Havelock's Preface it appears that the liberal regards all political and moral convictions as "negotiable" because he is extremely tolerant. Havelock applies the implicit maxim of conduct to the relations between the United States and Soviet Russia today. For all one can know from his book, he would have given the same advice during the conflict between the Western democracies and the Fascist regimes at the time of the Munich conference. At any rate he does not seem to have given thought to the question of whether Tolerance can remain tolerant when confronted with unqualified Intolerance or whether one must not fall back in the end on "moral convictions" which are not "negotiable." In almost all these points Havelock is liberal in the sense in which the word is commonly used here and now. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Crisis of Meaning in Sartor Resartus—Thomas Carlyle's Pioneering Work in Articulating and Addressing the Existential ConfrontationFrank Martelawhat i call an "existential confrontation" is the encounter with the possibility that human life is absurd: created for no purpose and devoid of any lasting value or meaning. It is "the hour of terror at the world's vast meaningless grinding" that William James (Will to Believe 173) examines, described by Todd May (...) (xi) as "the confrontation of our need for meaning with the unwillingness of the Universe to yield it to us." This confrontation with the existential void and the potential absurdity of human existence is often not just an intellectual dilemma, but felt as a deep personal crisis accompanied by melancholia, angst, nausea, or even suicidal thoughts. Young William James confessed in a letter to a friend that "all last winter" he "was on the continual verge of suicide" (quoted in Gunnarsson), writing later that "too much questioning" leads "to the edge of the slope" wherein lies "nightmare or suicidal view of life" (James, "Is Life Worth Living?" 6). Similarly, Leo Tolstoy (54) reports how his inability to identify a lasting meaning of life drove him to a "state of lunacy" where "the best I could do was to hang myself."Despite a few earlier allusions—most famously the Book of Ecclesiastes proclaiming that "all is vanity and a striving after wind," and Shakespeare's Macbeth lamenting that life is "a tale told by an idiot … signifying nothing"—the existential confrontation is predominantly a modern phenomenon (Martela, A Wonderful Life). The modern history of descriptions of existential confrontations start at the turn of the nineteenth century, and includes Søren Kierkegaard's Sickness Unto Death, Leo Tolstoy's A Confession, Fyodor Dostoevsky's Notes from Underground, Camus's Outsider, Sartre's Nausea, and T. S.Eliot's The Waste Land.There are many responses that the confrontation with the existential void has generated. Sartre embraced the lack of values imposed from outside and [End Page 80] emphasized human freedom. Human beings are "cast into this world … condemned to be free" without any "luminous realm of values" providing "justification or excuse," as Sartre famously summarized in "Existentialism Is a Humanism" (29). Other responses range from Søren Kierkegaard's leap of faith and William James's will to believe to Albert Camus's happiness from absurdity.While some of the responses end up finding a new way of connecting with God and faith, and others are explicitly atheistic, embracing the "death of God," a common thread in most responses is an acknowledgment of the situatedness of human experience and an emphasis placed on human subjectivity and the opportunity to live one's life more authentically. While existentialism, broadly conceived, is often seen as the central philosophical tradition dealing with the existential void, the confrontation was very much alive in the United States as well, visible in both literature and philosophy. As already alluded, William James had an existential confrontation in his youth, writing about the topic in "Is Life Worth Living" and other essays in Will to Believe. There has also been much back-and-forth between Europe and the United States around these themes, with the influences crossing the Atlantic on many occasions. For example, William James cites Thomas Carlyle in Will to Believe, while Sartre cites William James in Nausea, when discussing themes related to the existential confrontation. Similarly, Emerson inspired Nietzsche who inspired Josiah Royce. Typically, the histories tracing the early encounters with the existential confrontation acknowledge Friedrich Nietzsche, Søren Kierkegaard, and Fyodor Dostoevsky as key nineteenth-century predecessors to Existentialism, as all faced directly the question of the meaning of life and the dreadful possibility that life might not have any meaning or value to it.However, there is a key author usually not mentioned in these histories, despite the fact that he played a pivotal role in introducing existentialist themes to the English-speaking audience, coining the phrase "meaning of life" in the English language. Thus, in writing the prehistory of Existentialism, we need to examine Thomas Carlyle and his Sartor Resartus, which has been described by literary historians as "one of... (shrink)

The English critic Bentley first proposed emending the transmitted text of Troades 1109 from teget, the reading of all manuscripts, to leget. Bentley's suggestion subsequently gained wide acceptance and was printed in many later editions of the tragedies, including those of Leo , Richter , and Moricca . More recent critics have favoured retention of the manuscript reading. Carlsson, for example, underlines the distinctive alliterative quality which the reading teget imparts to the line; and the latest commentator on the Troades (...) has produced a spirited defence of the transmitted text: Andromache has not yet realized the condition of the corpse, and is thinking, not of gathering up fragmented limbs, but merely of the formal requirements of burial. What Carlsson defends on grounds of alliteration should be retained on grounds of sense: teget tumuloque tradet is a doublet of which the second part makes clear the religious meaning of the first, more general, word.

Leo Strauss and Eric Voegelin were political theorists of the first rank whose impact on the study of political science in North America has been profound. A study of their writings is one of the most expeditious ways to explore the core of political science; comparing and contrasting the positions both theorists have taken in assessing that core provides a comprehensive appreciation of the main options of the Western tradition. In fifty-three recently discovered letters, Strauss and Voegelin explore the nature (...) of their similarities and differences, offering trenchant observations about one another's work, about the state of the discipline, and about the influences working on them. The correspondence fleshes out many assumptions made in their published writings, often with a frankness and directness that removes all vestiges of ambiguity. Included with the correspondence are four pivotal re-published essays—"Jerusalem and Athens: Some Preliminary Reflections", "The Gospel and Culture", "Immortality: Experience and Symbol", and "The Mutual Influence of Theology and Philosophy" —and commentaries by James L. Wiser, Hans-Georg Gadamer, Stanley Rosen, Thomas J. J. Altizer, Timothy Fuller, Ellis Sandoz, Thomas L. Pangle, and David Walsh. (shrink)

One of the key ethical debates in Russian religious thought, initiated by Leo Tolstoy, concerned the question of nonresistance to evil by force. The purpose of this article is to assess the influence of Kant’s ethics and philosophy of religion on the course of this debate and to determine the place and significance of the arguments and considerations expressed on this issue by Semyon Frank in the early and late periods (1908 and 1940s) of his work. To this end I (...) reconstruct the general course of the debate, notably the positions and arguments of Leo Tolstoy, Vladimir Solovyov, Ivan Ilyin and Nikolai Berdyaev. Beginning with Tolstoy, Russ­ian thinkers introduced the original ethical content of the idea of nonresistance derived from the Gospel into the ethics of duty borrowed from Kant. The Tolstoy version of this idea was challenged mainly from two directions: from the Kantian grounding of the legitimacy of coercion and attempts to bring in styles of moral thinking other than the ethic of duty. Ilyin’s apolo­gia for the use of force in the struggle against evil prompted Russian émigré thinkers to take a closer look at Tolstoy’s ethical concept and pay attention to its positive content. On this basis Berdyaev and especially Frank create their version of the Christ-centered ethic of salvation which, in the perspective of “protecting the world against evil” includes the ethic of duty and links it with the possibility of using force, always a wrongful act, but one justified “in a situation of extreme need”.

Anyone who is seriously interested in Wittgenstein's thought on ethics and religion should encounter the mind of Cyril Barrett through this volume. Hendrix College Conway, Arkansas JOHN CHURCHILL Faith and Political Philosophy: The Correspondence Between Leo Strauss and Eric Voegelin, 1934-1964. Trans. and ed. (...) by PETER EMBERLEY and BARRY COOPER. University Park, Penn.: The Penn· sylvania State University Press, 1993. Pp. xxvi + 368. $45.00 (Cloth). Those of us who have followed the development of Leo Strauss's and Eric Voegelin's thought with passionate interest over the years owe a debt of gratitude to Professors Peter Emberley of Carleton University, Ottawa, and Barry Cooper of the University of Calgary for presenting us with yet another opportunity to reflect upon certain well defined aspects of the thinking of these important political philosophers, and to confirm views that we have long held about the cordial relationship that existed between these two men, despite frequent reports to the contrary. Prefaced by an insightful "Introduction" by Emberley and Cooper, which almost constitutes a commentary on the correspondence, Faith and Political Philosophy is divided into three parts. In Part One, the editors present us with their English translation of the fifty-two extant letters (a few letters appear to have been lost) exchanged between Strauss and Voegelin during the years 1934 to 1964. (For the most part, Strauss and Voegelin corresponded with one another in German.) Because Strauss wrote most, if not all, of his letters longhand, the editors inform us that some passages from Strauss's letters were especially difficult to decipher, and that, on occasion, they had to have re· course to German-speaking persons familiar with the German academic idiom of the 1930s and '40s in order to make sense of what was said. Voegelin, it seems, also had trouble decoding Strauss's handwriting, and admits on one occasion to being unable to read the writing or make sense of Strauss's point. By contrast, Voegelin, we are told, was very much easier to transcribe, since his letters, although, on average, longer than Strauss's, were typewritten. Part Two contains four essays, two by each of the philosophers, on the relationship of reason to reve- BOOK REVIEWS 539 lation-a central theme of the letters, a theme that is explicitly addressed in the letters dating from the late 1940s and early 1950s, and tacitly present in much of the remaining correspondence that is of an academic nature. This theme also attracts the attention of all of the commentators in Part Three, and is plainly the source of the title for the book. All four essays are familiar to Strauss-Voegelin scholars, having been published in various venues. And, finally, Part Three is a collection of eight commentaries on the correspondence by recog· nized scholars, some of whom are frankly famous in academic circles and beyond (e.g., H. G. Gadamer, who, for my tastes, should have had more to say about Voegelin). These commentaries are generally of a very high quality, although curiously, given the theme, most of the commentators seem to be more attuned to modern reference points rather than to the ancient ones with which both Strauss and Voegelin were often in dialogue. The effect of this is particularly noticeable with respect to observations made about Voegelin. Voegelin frequently saw himself in debate with the fathers of the early Church (as his piece " The Gospel and Culture " bears witness), and unfortunately this is not obvious from these commentaries. Still, while exploring the im· plications of the positions taken by Strauss and Voegelin in light of their formally published writing, the commentators make many interesting and, ~t times, controversial observations about one or both of the letter-writers. In this brief review, we will limit ourselves to commenting solely on parts One and Three. This said, perhaps we might open with a general observation about the nature of the correspondence as a whole. As one might expect, the content of the correspondence between Strauss and Voegelin is by no means solely academic and... (shrink)

Citing the Lincoln Savings and Loan scandal, the Leo Frank murder trial, and other cases, author William Simon takes a fresh look at the ethics of lawyering.

Franke, Dulcinati and Pouscoulous also examine a form of covert lying, by considering to what extent speakers use implicatures to deceive their addressee. The participants in their online signaling game had to describe a card, which a virtual coplayer then had to select. When the goal was to deceive rather than help the coplayer, participants produced more false descriptions (overt lies), but also more uninformative descriptions (covert lies by means of an implicature).

When placed into longer historical perspective using an interdisciplinary approach that fuses historical anthropology, history and political science, as well as hitherto unutilized primary sources, it can be demonstrated that the newly independent Indian Union right from the start under Nehru used constitution and law as instruments of subjugation that, since the latter remained incomplete, have prepared the ground for a war without end in the Naga Hills of Northeast India. Moreover, its history since the 1820s shows that constitution- and (...) law-making are in essence shaped by power politics only to be countered by force, leading in this constellation to an unending guerrilla war transforming ever larger circles of terrain into a low- level war-zone and firmly enthroning a culture of violence with all its concomitants.

Intonation plays an integral role in comprehending spoken language. Listeners can rapidly integrate intonational information to predictively map a given pitch accent onto the speaker's likely referential intentions. We use mouse tracking to investigate two questions: (a) how listeners draw predictive inferences based on information from intonation? and (b) how listeners adapt their online interpretation of intonational cues when these are reliable or unreliable? We formulate a novel Bayesian model of rational predictive cue integration and explore predictions derived under a (...) concrete linking hypothesis relating a quantitative notion of evidential strength of a cue to the moment in time, relative to the unfolding speech signal, at which mouse trajectories turn towards the eventually selected option. In order to capture rational belief updates after concrete observations of a speaker's behavior, we formulate and explore an extension of this model that includes the listener's hierarchical beliefs about the speaker's likely production behavior. Our results are compatible with the assumption that listeners rapidly and rationally integrate all available intonational information, that they expect reliable intonational information initially, and that they adapt these initial expectations gradually during exposition to unreliable input.

In _A Philosophy of the Unsayable_, William Franke argues that the encounter with what exceeds speech has become the crucial philosophical issue of our time. He proposes an original philosophy pivoting on analysis of the limits of language. The book also offers readings of literary texts as poetically performing the philosophical principles it expounds. Franke engages with philosophical theologies and philosophies of religion in the debate over negative theology and shows how apophaticism infiltrates the thinking even of those (...) who attempt to deny or delimit it._ In six cohesive essays, Franke explores fundamental aspects of unsayability. In the first and third essays, his philosophical argument is carried through with acute attention to modes of unsayability that are revealed best by literary works, particularly by negativities of poetic language in the oeuvres of Paul Celan and Edmond Jabès. Franke engages in critical discussion of apophatic currents of philosophy both ancient and modern, focusing on Hegel and French post-Hegelianism in his second essay and on Neoplatonism in his fourth essay. He treats Neoplatonic apophatics especially as found in Damascius and as illuminated by postmodern thought, particularly Jean-Luc Nancy’s deconstruction of Christianity. In the last two essays, Franke treats the tension between two contemporary approaches to philosophy of religion—Radical Orthodoxy and radically secular or Death-of-God theologies. _A Philosophy of the Unsayable _will interest scholars and students of philosophy, literature, religion, and the humanities. This book develops Franke's explicit theory of unsayability, which is informed by his long-standing engagement with major representatives of apophatic thought in the Western tradition. "William Franke is an articulate spokesman for what cannot be said not only with regards to modern European poetry but also with respect to contemporary theology. _A Philosophy of the Unsayable _is essential reading for everyone working in religion and literature and in modern theology." — Kevin Hart, Edwin B. Kyle Professor of Christian Studies, University of Virginia __ "By now, it would seem that there could be no more to say about not-saying. Apophatic language and negative theology have been accused of meaninglessness, nihilism, and even ill-concealed ontologies. In this lovely and surprising book, William Franke not only deftly undoes these criticisms but shows that apophasis underlies and strangely grounds all language and thought, even of those very discourses that most vigorously reject it. _A Philosophy of the Unsayable_ demonstrates with elegance that there is indeed more to say, and more that is both meaningful and important." — Karmen MacKendrick, Le Moyne College__ "William Franke is an eminent scholar in comparative literature, who is schooled in philosophy and religion. He is recognized as one of the most creative contemporary thinkers working at the double intersection of philosophy and literature and philosophy and theology. _A Philosophy of the Unsayable_ shows an intellectual grasp of a dizzying array of discourses and sheds real light on all thinkers who are discussed." — Cyril O'Regan, Huisking Professor of Theology, University of Notre Dame_.

Academic performance enhancement or cognitive enhancement (CE) via stimulant drug use has received increasing attention. The question remains, however, whether CE solely represents the use of drugs for achieving better academic or workplace results or whether CE also serves various other purposes. The aim of this study was to put the phenomenon of pharmacological academic performance enhancement via prescription and illicit (psycho-) stimulant use (Amphetamines, Methylphenidate) among university students into a broader context. Specifically, we wanted to further understand students’ experiences, (...) the effects of use on students and other factors, such as pressure to perform in their academic and private lives. (shrink)

Compositionality is a key design feature of human language: the meaning of complex expressions is, for the most part, systematically constructed from the meanings of its parts and their manner of composition. This paper demonstrates that rudimentary forms of compositional communicative behavior can emerge from a variant of reinforcement learning applied to signaling games. This helps explain how compositionality could have emerged gradually: if unsophisticated agents can evolve prevalent dispositions to communicate compositional-like, there is a direct evolutionary benefit for adaptations (...) that exploit the systematicity in form-meaning mappings more rigorously.

Signalling games are popular models for studying the evolution of meaning, but typical approaches do not incorporate vagueness as a feature of successful signalling. Complementing recent like-minded models, we describe an aggregate population-level dynamic that describes a process of imitation of successful behaviour under imprecise perception and realization of similar stimuli. Applying this new dynamic to a generalization of Lewis’s signalling games, we show that stochastic imprecision leads to vague, yet by-and-large efficient signal use, and, moreover, that it unifies evolutionary (...) outcomes and helps avoid sub-optimal categorization. The upshot of this is that we see ‘as-if’-generalization at an aggregate level, without agents actually generalizing. _1_ Introduction _2_ Background _2.1_ Sim-max games and conceptual spaces _2.2_ Vagueness in sim-max games and conceptual spaces _2.3_ Vagueness, functional pressure, and transmission biases _3_ Imprecise Imitation _3.1_ Replicator dynamic in behavioural strategies _3.2_ Noise-perturbed conditional imitation _4_ Exploring Imprecise Imitation _4.1_ Setting the stage _4.2_ Simulation set-up _4.3_ Measures of interest _4.4_ Results _5_ Discussion _5.1_ Levels of vagueness _5.2_ Evolutionary benefits of imprecision _5.3_ Related work _6_ Conclusion Appendix.

According to standard linguistic theory, the meaning of an utterance is the product of conventional semantic meaning and general pragmatic rules on language use. We investigate how such a division of labor between semantics and pragmatics could evolve under general processes of selection and learning. We present a game‐theoretic model of the competition between types of language users, each endowed with certain lexical representations and a particular pragmatic disposition to act on them. Our model traces two evolutionary forces and their (...) interaction: (i) pressure toward communicative efficiency and (ii) transmission perturbations during the acquisition of linguistic knowledge. We illustrate the model based on a case study on scalar implicatures, which suggests that the relationship between underspecified semantics and pragmatic inference is one of coevolution. (shrink)

We reopen the investigation into the formal and conceptual relationship between bidirectional optimality theory (Blutner in J Semant 15(2):115–162, 1998 , J Semant 17(3):189–216, 2000 ) and game theory. Unlike a likeminded previous endeavor by Dekker and van Rooij (J Semant 17:217–242, 2000 ), we consider signaling games not strategic games, and seek to ground bidirectional optimization once in a model of rational step-by-step reasoning and once in a model of reinforcement learning. We give sufficient conditions for equivalence of bidirectional (...) optimality and the former, and show based on numerical simulations that bidirectional optimization may be thought of as a process of reinforcement learning with lateral inhibition.

Wang (_Philosophy & Technology_ 35, 2022) introduces a Foucauldian power account of algorithmic transparency. This short commentary explores when this power account is appropriate. It is first observed that the power account is a constructionist one, and that such accounts often come with both factual and evaluative claims. In an instance of Hume’s law, the evaluative claims do not follow from the factual claims, leaving open the question of how much constructionist commitment (Hacking, 1999) one should have. The concept of (...) acts in equilibrium (Nozick, 1981) is then used to explain how different individuals reading Wang can end up with different evaluative attitudes towards algorithmic transparency, despite factual agreement. The commentary concludes by situating constructionist commitment inside a larger question of how much to think of our actions, identifying conflicting arguments. (shrink)

There is substantial support for the general idea that a formalization of comprehenders' expectations about the likely next word in a sentence helps explaining data related to online sentence processing. While much research has focused on syntactic, semantic, and discourse expectations, the present event‐related potentials (ERPs) study investigates neurolinguistic correlates of pragmatic expectations, which arise when comprehenders expect a sentence to conform to Gricean Maxims of Conversation. For predicting brain responses associated with pragmatic processing, we introduce a formal model of (...) such Gricean pragmatic expectations, using an idealized incremental interpreter. We examine whether pragmatic expectancies derived from this model modulate the amplitude of the N400, a component that has been associated with predictive processing. As part of its parameterization, the model distinguishes genuine pragmatic interpreters, who expect maximally informative true utterances, from literal interpreters, who only expect truthfulness. We explore the model's non‐trivial predictions for an experimental setup which uses picture‐sentence verification with ERPs recorded at several critical positions in sentences containing the scalar implicature trigger some. We find that Gricean expectations indeed affect the N400, largely in line with the predictions of our model, but also discuss discrepancies between model predictions and observations critically.

Modern society makes extensive use of automated algorithmic decisions, fueled by advances in artificial intelligence. However, since these systems are not perfect, questions about fairness are increasingly investigated in the literature. In particular, many authors take a Rawlsian approach to algorithmic fairness. This article aims to identify some complications with this approach: Under which circumstances can Rawls’s original position reasonably be applied to algorithmic fairness decisions? First, it is argued that there are important differences between Rawls’s original position and a (...) parallel algorithmic fairness original position with respect to risk attitudes. Second, it is argued that the application of Rawls’s original position to algorithmic fairness faces a boundary problem in defining relevant stakeholders. Third, it is observed that the definition of the least advantaged, necessary for applying the difference principle, requires some attention in the context of algorithmic fairness. Finally, it is argued that appropriate deliberation in algorithmic fairness contexts often require more knowledge about probabilities than the Rawlsian original position allows. Provided that these complications are duly considered, the thought-experiment of the Rawlsian original position can be useful in algorithmic fairness decisions. (shrink)

Game theoretic pragmatics is a small but growing part of formal pragmatics, the linguistic subfield studying language use. The general logic of a game theoretic explanation of a pragmatic phenomenon is this: the conversational context is modelled as a game between speaker and hearer; an adequate solution concept then selects the to‐be‐explained behavior in the game model. For such an explanation to be convincing, both components, game model and solution concept, should be formulated and scrutinized as explicitly as possible. The (...) article demonstrates this by a concise overview of both evolutionary and non‐evolutionary approaches to game theoretic pragmatics, arguing for the use of agent‐based micro‐dynamics within evolutionary, and for the use of epistemic game theory within non‐evolutionary approaches.

Language use and interpretation is heavily contingent on context. But human interlocutors need not always agree what the actual context is. In game theoretic approaches to language use and interpretation, interlocutors’ beliefs about the context are the players’ beliefs about the game that they are playing. Together this entails that we need to consider cases in which interlocutors have different subjective conceptualizations of the game they are in. This paper therefore extends iterated best response reasoning, as an established model for (...) pragmatic reasoning, to games with unawareness. This extension not only leads to more plausible context models for many communicative situations, but also to improved predictions for otherwise problematic cases and an extension of the scope of pragmatic phenomena that can be captured by game theoretic analysis.

Recent advances in artificial intelligence offer many beneficial prospects. However, concerns have been raised about the opacity of decisions made by these systems, some of which have turned out to be biased in various ways. This article makes a contribution to a growing body of literature on how to make systems for automated decision-making more transparent, explainable, and fair by drawing attention to and further elaborating a distinction first made by Nozick between first-level bias in the application of standards and (...) second-level bias in the choice of standards, as well as a second distinction between discrimination and arbitrariness. Applying the typology developed, a number of illuminating observations are made. First, it is observed that some reported bias in automated decision-making is first-level arbitrariness, which can be alleviated by explainability techniques. However, such techniques have only a limited potential to alleviate first-level discrimination. Second, it is argued that second-level arbitrariness is probably quite common in automated decision-making. In contrast to first-level arbitrariness, however, second-level arbitrariness is not straightforward to detect automatically. Third, the prospects for alleviating arbitrariness are discussed. It is argued that detecting and alleviating second-level arbitrariness is a profound problem because there are many contrasting and sometimes conflicting standards from which to choose, and even when we make intentional efforts to choose standards for good reasons, some second-level arbitrariness remains.

As more decisions are made by automated algorithmic systems, the transparency of these systems has come under scrutiny. While such transparency is typically seen as beneficial, there is a also a critical, Foucauldian account of it. From this perspective, worries have recently been articulated that algorithmic transparency can be used for manipulation, as part of a disciplinary power structure. Klenk (Philosophy & Technology 36, 79, 2023) recently argued that such manipulation should not be understood as exploitation of vulnerable victims, but (...) rather as indifference to whether the information provided enhances decision-making by revealing reasons. This short commentary on Klenk uses Berlin’s (1958) two concepts of liberty to further illuminate the concept of transparency as manipulation, finding alignment between positive liberty and the critical account.

This essay represents part of an effort to rewrite the history metaphysics in terms of what philosophy never said, nor could say. It works from the Neoplatonic commentary tradition on Plato's Parmenides as the matrix for a distinctively apophatic thinking that takes the truth of metaphysical doctrines as something other than anything that can be logically articulated. It focuses on Damascius in the 5—6th century AD as the culmination of this tradition in the ancient world and emphasizes that Neoplatonism represents (...) the crisis of Greek metaphysics on account of the inability to give a rational account of foundations for knowing and of the ultimate principle of beings. Neoplatonism discovered how all such ultimate principles were necessarily beyond the reach of reason and speech. This apophatic insight is drawn out with the help of contemporary criticism of Neoplatonic philosophy, defining also some points of divergence. The essay then discusses the motives for thinking the unsayable in postmodern times on the basis of this parallel with Neoplatonic thought. Discourse's becoming critical of itself to the point of self-subversion animates them both. However, the tendency in postmodern thought to totally reject theology, including negative theology, is a betrayal of its own deepest motivations. This tendency is debated through an examination of the thought of Jean-Luc Nancy. While any traditional discourse can be negated, the negating and self-negating capacity of discourse itself is infinite, and this is where a perennial negative theological philosophy of the unsayable is to be located. Language, eminently the language of philosophy, as infinitely open, points in a direction which becomes equally and ineluctably theological. (shrink)

Quantum theory of Lorentz invariant local scalar fields without restrictions on 4-momentum spectrum is considered. The mass spectrum may be both discrete and continues and the square of mass as well as the energy may be positive or negative. One may assume the existence of such fields only if they interact with ordinary fields very weakly. Generalization of Kallen-Lehmann representation for propagators of these fields is found. The considered generalized fields may violate CPT-invariance. Restrictions on mass-spectrum of CPT-violating fields are (...) found. Local fields that annihilate vacuum state and violate CPT-invariance are constructed in this scope. Correct local relativistic generalization of Lindblad equation for density matrix is written for such fields. This generalization is particularly needed to describe the evolution of quantum system and measurement process in a unique way. Difficulties arising when the field annihilating the vacuum interacts with ordinary fields are discussed. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Literature 29.1 (2005) 73-88 [Access article in PDF] Virgil, History, and Prophecy William Franke Vanderbilt University Virgil has been very widely acclaimed as a prophet, but the grounds of this acclaim have shifted in the course of history. From ancient and especially from medieval times, this recognition was traditionally accorded him first and foremost, if not exclusively, on the basis of a passage from the Fourth (...) Eclogue celebrating the birth of a new progeny ("progenies nova") from heaven and the consequent renewal of the world.1 This passage lent itself to Christian messianic interpretations, thanks especially to its reference to a Virgin ushering in a return of the golden age of peace on earth ("iam redit et uirgo, redeunt Saturnia regna"). Historical research reveals Virgil to have, in all probability, intended in this text to hyperbolically hail the birth of a son to a particular Roman consul.2 Yet, even apart from historical intentions and inevitable doubts about them, to pin Virgil's claim to being a prophet to this text is to miss the momentous discovery that makes him truly a prophet in a way unprecedented in pagan antiquity.Modern treatments of Virgil as prophet have not remained beholden to this Christian medieval framework and have opened suggestive avenues for more accurate elucidation of Virgilian prophecy, particularly in terms of its own historical context and the role of the Latin vates in Imperial Rome.3 What I wish to propose, however, is not a more accurately historicized understanding of prophecy in Virgil, but rather a philosophical interpretation of the conception of history as prophetic that is realized in the text of the Aeneid. This is actually analogous to the medieval Christian misprision of Virgil in that it focusses on Virgil's potential significance in a new and different historical context, our own. The justification for this approach lies in the fact that historical research into prophecy during the Augustan Empire cannot exhaustively [End Page 73] explain the significance of Virgil's text in its astonishing creation of an original conception of history as prophetic, nor in its potential to illuminate the nature of prophecy as it may concern us today. Study of Virgil can help make the concept of prophecy vital to reflection on history and the structure of time in our own post-Heideggerian era.The question of whether Virgil foresaw the birth of Christ concerns prophecy only in the relatively banal sense of being able to foretell the future. In this, Virgil would be no different from myriad seers and divines and sorcerers with which the ancient world was rife. But the originality of Virgil, his particular claim to being an authentic prophet rather than simply, like many other major Roman authors, to have incorporated prophetic topoi into his works rests on his surpassing prophecy in precisely this sense. It is Virgil's single-handed invention, as if out of nowhere, of a genuinely prophetic mode of understanding history that is the seeming miracle on which his justly deserved fame as a prophetic poet has every right to rest.Whereas the certainly rather forced Christian interpretation of the Fourth Eclogue concerns "prophecy" only in a surface sense of factually foretelling the future, the deep meaning of prophecy as it develops in Virgil and Dante and the whole lineage of prophetic poets they foster down through Tasso, Spenser, Milton, and Blake, concerns rather the interpretation of history from its endpoint and seen as a whole, so that every moment in that history receives new meaning in light of a synoptic vision. In the biblical prophetic tradition, this perspective extends even beyond history and time altogether, and this marks a crucial difference from Virgil, whose end-vision is envisaged primarily as intrahistorical rather than as eschatological or as beyond the end (eschaton) of history. Still, in Virgil, just as in the Bible, the prophetic vantage point transcends history in order to understand it as a whole. This transcendence is expressed, among other ways, in the claim to divine inspiration. Whether this claim to inspiration be understood as a figure for heightened human potency or... (shrink)
