Healey et al. use experiments with chat dialogues to test the hypothesis that language co‐ordination is driven by ‘running repairs’. They replace signals of understanding such as “okay” with weaker, ‘spoof’ signals like “ummm”, and replace specific requests for clarification like “on the left?” with signals that suggest a higher degree of misunderstanding like “what?”. The latter manipulation causes participants to switch rapidly to more abstract forms of referring expression.

Healey et al. introduce the special issue with a brief overview of work on communication in the Cognitive Sciences and some of the historical and conceptual influences that have marginalized the study of miscommunication. Drawing on more recent work in Cognitive Science and Conversation Analysis they argue that miscommunication is in fact a highly structured, ubiquitous phenomenon that is fundamental to human interaction.

Exaptations are adaptations that have undergone a major change in function. By recruiting genes from sources originally unrelated to vision, exaptation has allowed for sudden and critical photosensory innovations, such as lenses, photopigments, and photoreceptors. Here we review new or neglected findings, with an emphasis on unicellular eukaryotes (protists), to illustrate how exaptation has shaped photoreception across the tree of life. Protist phylogeny attests to multiple origins of photoreception, as well as the extreme creativity of evolution. By appropriating genes and (...) even entire organelles from foreign organisms via lateral gene transfer and endosymbiosis, protists have cobbled photoreceptors and eyespots from a diverse set of ingredients. While refinement through natural selection is paramount, exaptation helps illustrate how novelties arise in the first place, and is now shedding light on the origins of photoreception itself. -/- .

Social robots have limited social competences. This leads us to view them as depictions of social agents rather than actual social agents. However, people also have limited social competences. We argue that all social interaction involves the depiction of social roles and that they originate in, and are defined by, their function in accounting for failures of social competence.

The contributors to The Moral of the Story, all preeminent political theorists, are unified by their concern with the instructive power of great literature. This thought-provoking combination of essays explores the polyvalent moral and political impact of classic world literatures on public ethics through the study of some of its major figures-including Shakespeare, Dante, Cervantes, Jane Austen, Henry James, Joseph Conrad, Robert Penn Warren, and Dostoevsky. Positing the uniqueness of literature's ability to promote dialogue on salient moral and intellectual virtues, (...) editor Henry T. Edmonson III has culled together a wide-ranging exploration of such fundamental concerns as the abuse of authority, the nature of good leadership, the significance of "middle class virtues" and the needs of adolescents. This collection reinvigorates the study of classic literature as an endeavor that is not only personally intellectually satisfying, but also an inimitable and unique way to enrich public discourse.

This article deals with the methodologies commonly used in the framework of the structural approach to social representations. It concerns free and hierarchical evocations, the characterization questionnaire, the similarity analysis, the basic cognitive schemes model, the attribute-challenge technique and the test of context independence. More than a simple review of these methodologies, it offers a critical approach concerning the problems encountered and related to: thresholds or “cutoff points” used to diagnose the structure and the accuracy of the structural diagnosis, grouping (...) methods employed to reduce the corpus of verbal associations, the dilemma between reliability and feasibility, especially in field research, the adequacy and number of modalities of response in the framework of the structural diagnosis. Following this evaluation, this article suggests potential solutions to overcome these methodological limitations. Moreover, as methodological issues are closely related to theoretical questions, the link between social representation theory and identity approaches is discussed. (shrink)

Single crystal samples of n - deformed to a permanent strain of 2% at room temperature under multiple-slip conditions contain faulted dipoles whose density exhibits some dependence on load orientation. Although FDs are hard to observe after compression along [210], they are profuse and congregated in places in the [1 1 8.6] load orientation. They exhibit most of the topological characteristics of FDs formed under single slip as reported by Grégori and Veyssière such as elongation in the screw direction of (...) the primary d 011] slip direction and a noticeable shape asymmetry. It is shown further that, in the [1 1 8.6] samples, bundles of FDs originate at jogs that result from intersection with forest dislocations of appropriate Burgers vectors. A mechanism for FD nucleation is proposed on the basis of asymmetrical dissociation of the parent d 011] dislocation and specific impingements between the various partials on two adjacent octahedral planes. Implications of the FD nucleation at jogs on the load orientation dependence of the FD density are discussed. (shrink)

In this note we show that the classical modal technology of Sahlqvist formulas gives quick proofs of the completeness theorems in [8] (D. Gregory, Completeness and decidability results for some propositional modal logics containing "actually" operators, Journal of Philosophical Logic 30(1): 57-78, 2001) and vastly generalizes them. Moreover, as a corollary, interpolation theorems for the logics considered in [8] are obtained. We then compare Gregory's modal language enriched with an "actually" operator with the work of Arthur Prior now (...) known under the name of hybrid logic. This analysis relates the "actually" axioms to standard hybrid axioms, yields the decidability results in [8], and provides a number of complexity results. Finally, we use a bisimulation argument to show that the hybrid language is strictly more expressive than Gregory's language. (shrink)

Strict moderate invariantism is the ho-hum, ‘obvious’ view about knowledge attributions. It says knowledge attributions are often true and that only traditional epistemic factors like belief, truth, and justification make them true. As commonsensical as strict moderate invariantism is, it is equally natural to withdraw a knowledge attribution when error possibilities are made salient. If strict moderate invariantism is true, these knowledge-denials are often false because the subject does in fact know the proposition. I argue that strict moderate invariantism needs (...) an explanation of this phenomenon, but it does not have one. That is significant, for if strict moderate invariantism does not square with ordinary intuition, then it cannot rely on ordinary intuition for support. Section 1 introduces the concept of epistemic relevance blindness, which says ordinary subjects are generally insensitive to whether or not error possibilities are relevant to knowledge attributions. Section 2 focuses on Patrick Rysiew’s influential strict moderate invariantist pragmatic explanation of knowledge-denials and argues that such pragmatic explanations of knowledge-denials depend on attributors being epistemic relevance blind. Section 3 targets psychological explanations of epistemic relevance blindness offered separately by Jennifer Nagel and Mikkel Gerken. I argue that strict moderate invariantists lack a plausible explanation of epistemic relevance blindness. (shrink)

It has now been more than 50 years since H. L. A Hart and Lord Patrick Devlin first squared off in perhaps the most celebrated jurisprudential debate of the twentieth‐century (1959–1967). The central issue in that dispute—whether the state may criminalize immoral behavior as such—continues to be debated today, but in a vastly changed legal landscape. In this article I take a fresh look at the Hart‐Devlin debate in the light of five decades of social and legal changes.

This article deals with the exegetical method of Hugh of Flavigny, a Lotharingian monk who composed a world chronicle between c. 1085 and 1102. The second half of Hugh’s work was composed in defence of Pope Gregory VII , whose programme of reform and death in exile was the object of much contemporary debate. In his defence of Gregory’s pontificate, Hugh — like many pro-papal writers — had recourse to a polemical interpretation of Scripture that had three main (...) purposes: to justify the legitimacy of Pope Gregory’s measures against King Henry IV of Germany , to prophesise future divine retribution against the apparently victorious party of Henry IV, and to promise future rewards for the Gregorian ‘martyrs’ who had suffered for the cause of righteousness. Hugh’s polemical interpretation of the Bible was very similar in method and intent to others contemporary and near-contemporary supporters of Gregory VII, such as Bernhard of Hildesheim, Manegold of Lautenbach and Bonizo of Sutri. However, in addition to sharing some of the typical concerns and methods of pro-papal polemic, Hugh’s exegesis demonstrates considerable originality, especially when dealing with the reconciliation of apparently contradictory texts and when explaining the process of spiritual regeneration.

Two articles in the September–October 2022 issue of the Hastings Center Report discuss health‐related reasons that people might have to actively bring their lives to an end. In one, Brent Kious considers the situation of a person who, because of illness, becomes a burden on loved ones. A person in such a situation might prefer to die, and Kious argues that, while there is no obligation to hasten one's death, the choice to do so could sometimes be reasonable. In a (...) second article, Henri Wijsbek and Thomas Nys discuss a case in the Netherlands in which a woman with severe dementia was euthanized at a point when her advance euthanasia directive did not align with what she said, when asked, about death. Wijsbek and Nys defend the authority of her advance directive against a range of objections.In a third article, Henry Silverman and Patrick Odonkor, physicians at the University of Maryland Medical Center, where the first pig‐to‐human heart transplantation was performed in early 2022, develop recommendations for clinical trials of porcine heart transplantation. And an essay in the issue criticizes the allocation recommendations developed for Covid‐19 vaccines by the U.S. Centers for Disease Control and Prevention's Advisory Committee on Immunization Practices.

In lieu of an abstract, here is a brief excerpt of the content:Another Look at Silence and Knowledge of God in Ignatius's Letter to the EphesiansRyan Patrick Budd"The man whose delight is in the Lord's teaching knows the art of sitting still in the right place."—Robert Alter, The Art of Biblical PoetryIn this essay, I attempt to supplement the better analyses of St. Ignatius of Antioch's Epistle to the Ephesians (Ign. Eph.) 14.1 through 15.3 with structural insights. The main (...) fruit of the analysis will be to affirm the "mystical" meaning of Ignatius's concept of "hearing Christ's silence": the mature believer, who truly understands Christ's word, will be able to hear the silence of Christ—meaning, to understand Christ's hidden and mysterious Godhead—because Christ dwells within the believer as in a temple. The essay will proceed in three sections: First, a review of the more substantive commentaries on "silence" in Ign. Eph. 14–15; second, a presentation of a potential structure of the passage and a commentary on what that structure, if correct, would yield; and third, a very brief confirmation of the findings by reference to themes in St. Paul's own Epistle to the Ephesians.Scholarly Commentary on Ignatius and "Silence"In discussing Ign. Eph. 14–15, scholars have come to a wide variety of views, for almost as many reasons, as to what Ignatius means when he says the following: [End Page 451]It is better to be silent and to be, than to speak and not be. Teaching is good, if the one speaking should do. There is, then, one Teacher, who "spoke and it came to be," and even the things he has done silently are worthy of the Father. The one truly hearing the word of Jesus can also hear his [Jesus's] silence, that he might be fully made, that he might act through what he says and be understood through his (the believer's) silence.(15.1–2)1There are, however, two predominant camps into which one could group the different scholarly opinions: the first camp holds that Ignatius merely is speaking about integrity, the correspondence between words and deeds;2 the second camp holds that he is enunciating a kind of Christian mysticism.3 Two prominent members of the second camp, Virginia Corwin and Gregory Vall, though quite distinct in their views of the bishop of Antioch, provide reasoning that I find decisive in favor of recognizing that Ignatius—while certainly emphasizing a true correspondence between words and deeds—carries the point further than simple moralizing.Virginia Corwin's "Reserve of Deity" and the Believer's Knowledge of ChristCorwin, in her analysis of the passage, points toward a "reserve" existing "behind" the visible works of Christ, which is to be identified with his invisible, and thus "silent," Godhead, which one who truly hears his word can also "hear." She acknowledges, however, that Ignatius first recognizes Christ as an example of a truly effective teacher due to the absolute [End Page 452] correspondence between his words and his acts. She writes, "Christ... is a teacher unlike most, since there is no contrast at all between his profession and his actions.... He has an absolute clarity and a complete lack of any hypocrisy."4 The result of this recognition is not to stress ethical integrity, however important: it is to argue that, because of the correspondence between Christ's words and his silent acts and his even more silent person, the one who knows his words can come to a deep, profound, and infallible knowledge of who he is, himself.Corwin argues that there is something more about this Teacher than the mere—though impressive—integrity of his message:But it is not only the integrity of the teacher that distinguishes him, but his unique power: "He spoke and it came to pass"; at these words to the minds of both the writer and the hearers of the letter must have occurred the image of the mighty acts of creation.... It is precisely because the words of Jesus are in a sense mighty acts that they must be seen in the larger perspective.5Which "larger perspective" she means... (shrink)

Donald R. Gregory has recently argued that the monk Gaunilo's response to St Anselm's ontological argument succeeds in showing what is fundamentally wrong with any ontological argument, including modern modal versions. He holds that the Gaunilo strategy in fact demonstrates what it alleges, that reasoning which parallels the form and intent ofAnselm's reductio argument can ‘prove’ a priori the existence of quite unacceptable entities.

The fourteenth-century Greek hesychast and controversialist, Gregory Palamas, has been so successfully cast as "the other" in Western theological discourse that it can be difficult to gain a sympathetic hearing for him. In the first part of this book, Norman Russell traces the historical reception of Palamite thought in Orthodoxy and in the West, and investigates how "Palamism" was constructed in the early twentieth century by both Western and Eastern theologians (principally Martin Jugie and John Meyendorff) for polemical or (...) apologetic purposes. Russell argues that we need to go behind these ideological constructions in order to gain a true perception of the teaching of Gregory Palamas. In his recent survey of Palamite scholarship, Robert Sinkewicz noted that it is now time to raise the larger questions. The second part of the book attempts to do this, following the contours of Palamas' thinking in three areas: his relationship to tradition, his philosophy, and his theology. Russell shows that Palamite thought, when freed of misunderstanding and misrepresentation, has the potential to enrich our understanding of divine-human communion. This study contributes to the changing paradigm of scholarship on Palamas, nudging it towards the point at which Palamite thought can be used fruitfully by contemporary Western and Eastern theologians without the need to subscribe to what has been regarded as "Palamism".

The theory of lower previsions is designed around the principles of coherence and sure-loss avoidance, thus steers clear of all the updating anomalies highlighted in Gong and Meng's "Judicious Judgment Meets Unsettling Updating: Dilation, Sure Loss, and Simpson's Paradox" except dilation. In fact, the traditional problem with the theory of imprecise probability is that coherent inference is too complicated rather than unsettling. Progress has been made simplifying coherent inference by demoting sets of probabilities from fundamental building blocks to secondary representations (...) that are derived or discarded as needed.

In this paper, we defend the view that Spinoza is committed to allowing for the existence of a plurality of possible worlds, that his necessitarianism is merely moderate, not strict enough to exclude the possibility of other worlds. To show that evidence for attributing strict necessitarianism to Spinoza is lacking, we shall concentrate on Don Garrett's article, “Spinoza's Necessitarianism,” in the conviction that his case for attributing strict necessitarianism to Spinoza is the strongest one available.

"'There is only one thing that is certain, namely that we can have nothing certain; and therefore it is not certain that we can have nothing certain,' Samuel Butler once said, expressing in that mindbloggler all the elements required to form a classical paradox.

A comprehensive introduction to current research on the psychology of concept formation and use.

Inductively defined structures are ubiquitous in mathematics; their specification is unambiguous and their properties are powerful. All fields of mathematical logic feature these structures prominently: the formula of a language, the set of theorems, the natural numbers, the primitive recursive functions, the constructive number classes and segments of the cumulative hierarchy of sets. -/- This dissertation gives a mathematical characterization of a species of inductively defined structures, called accessible domains, which include all of the above examples except the set of (...) theorems. The concept of an accessible domain comes from Wilfried Sieg's analysis of proof-theoretic practices, starting with his dissertation. In particular, he noticed the special epistemological character of elements of an accessible domain: they can always be uniquely identified with their build-up. Generally, the unique build-up of elements justifies the principles of induction and recursion. -/- I use category theory to give an abstract characterization of accessible domains. I claim that accessible domains are all instances of initial algebras for endofunctors. Grounded in the historical roots of Sieg's discussions, this dissertation shows how the properties of initial algebras for endofunctors and accessible domains coincide in a satisfying and natural way. -/- Filling out this characterization, I show how important examples of accessible domains fit into this broad characterization. I first characterize some accessible domains by relatively simple functors (e.g. finite, polynomial, those that preserve certain colimits) where we can see how iterating the functor can produce the accessible domain. Then I describe accessible domains that result from more involved specifications (e.g. ordinals and segments of the cumulative hierarchies associated with CZF, IZF, and ZF) by relying heavily on algebraic set theory. I end with a discussion of some of the methodological features of category theory in particular that helped characterize accessible domains. (shrink)

Moral latitude is only ever a matter of coincidence on the most popular decision procedure in the literature on moral uncertainty. In all possible choice situations other than those in which two or more options happen to be tied for maximal expected choiceworthiness, Maximize Expected Choiceworthiness implies that only one possible option is uniquely appropriate. A better theory of appropriateness would be more sensitive to the decision maker’s credence in theories that endorse agent-centred prerogatives. In this paper, we will develop (...) and defend a modified version of this view that allows for agent-centred prerogatives and supererogation as part of its verdicts about appropriateness. (shrink)

(Updated 5/23/24) This unpublished paper, which readers should feel free to cite, is posted primarily for the historical record. In recent work that has, deservedly, received some attention, Paul R. Daniels presents and defends a non-standard theory of persistence that he dubs transdurantism, according to which persisting objects are temporally extended simples. This is exactly what I do in work dating back to Spring 2004. (This work includes this version of this paper, as well as later version that was presented (...) to the University of Rochester's Philosophy Department in 2005.) While this might be a total coincidence, I doubt that it is, especially given that 'transdurantism' appears as a name for a theory of persistence associated with me in at least two places in the literature, one of which includes a citation of this paper. The paper begins with a discussion of what I call 'locative relations' (the relations borne by material objects to the regions of space and time they occupy), which draws relevant distinctions that others have failed to draw. The results of this discussion are then used in constructing spatial analogues for the three established theories of persistence--endurantism, perdurantism, and exdurantism--as well as for transdurantism. Next, these four views concerning persistence are explicitly formulated and a defense of their formulation is offered. Finally, transdurantism's advantages and disadvantages relative to the other theories are discussed. The main goal of the paper is to challenge the trichotomy between the established theories by arguing that transdurantism is also a viable view concerning persistence through time. [Note: Befitting its status as a historical document, with the exception of some light editing to fix typos that might impede understanding, no changes have been made to the paper.]. (shrink)
