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. -/- .

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.

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.

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)

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.

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.

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".

This important book provides a theory about the nature of fiction, and about the relation between the author, the reader and the fictional text. The approach is philosophical: that is to say, the author offers an account of key concepts such as fictional truth, fictional characters, and fiction itself. The book argues that the concept of fiction can be explained partly in terms of communicative intentions, partly in terms of a condition which excludes relations of counterfactual dependence between the world (...) and the text. This communicative model is then applied to the following problems: how can something be 'true in the story' without being explicitly stated in the text? In what ways does interpreting a fictional story depend upon grasping its author's intentions? Is there always a unique best interpretation of a fictional text? What is the correct semantics for fictional names? What is the nature of our emotional response to a fictional work? In answering these questions the author explores the complex interaction between author, reader, and text. This interaction requires the reader to construct a 'fictional author' - a character in the story whose personality, beliefs and emotional states must be interpreted if the reader is to grasp the meaning of the work.

In Complicity and Moral Accountability, Gregory Mellema presents a philosophical approach to the moral issues involved in complicity. Starting with a taxonomy of Thomas Aquinas, according to whom there are nine ways for one to become complicit in the wrongdoing of another, Mellema analyzes each kind of complicity and examines the moral status of someone complicit in each of these ways. Mellema's central argument is that one must perform a contributing action to qualify as an accomplice, and that it (...) is always morally blameworthy to perform such an action. Additionally, he argues that an accomplice frequently bears moral responsibility for the outcome of the other's wrongdoing, but he distinguishes this case from cases in which the accomplice is tainted by the wrongdoing of the principal actor. He further distinguishes between enabling, facilitating, and condoning harm, and introduces the concept of indirect complicity. Mellema tackles issues that are clearly important to any case of collective and shared responsibility, yet rarely discussed in depth, always presenting his arguments clearly, concisely, and engagingly. His account of the nonmoral as well as moral qualities of complicity in wrongdoing--especially of the many and varied ways in which principles and accomplices can interact--is highly illuminating. Liberally sprinkled with helpful and nuanced examples, Complicity and Moral Accountability vividly illustrates the many ways in which one may be complicit in wrongdoing. "In Complicity and Moral Accountability, Gregory Mellema has made an immensely important contribution to the discussion of group morality and collective responsibility both within and far beyond professional academic philosophy. His clearly written book will be essential reading." --Fergus Kerr, Honorary Fellow, University of Edinburgh. (shrink)

At least since Aristotle’s famous 'sea-battle' passages in On Interpretation 9, some substantial minority of philosophers has been attracted to the doctrine of the open future--the doctrine that future contingent statements are not true. But, prima facie, such views seem inconsistent with the following intuition: if something has happened, then (looking back) it was the case that it would happen. How can it be that, looking forwards, it isn’t true that there will be a sea battle, while also being true (...) that, looking backwards, it was the case that there would be a sea battle? This tension forms, in large part, what might be called the problem of future contingents. A dominant trend in temporal logic and semantic theorizing about future contingents seeks to validate both intuitions. Theorists in this tradition--including some interpretations of Aristotle, but paradigmatically, Thomason (1970), as well as more recent developments in Belnap, et. al (2001) and MacFarlane (2003, 2014)--have argued that the apparent tension between the intuitions is in fact merely apparent. In short, such theorists seek to maintain both of the following two theses: (i) the open future: Future contingents are not true, and (ii) retro-closure: From the fact that something is true, it follows that it was the case that it would be true. It is well-known that reflection on the problem of future contingents has in many ways been inspired by importantly parallel issues regarding divine foreknowledge and indeterminism. In this paper, we take up this perspective, and ask what accepting both the open future and retro-closure predicts about omniscience. When we theorize about a perfect knower, we are theorizing about what an ideal agent ought to believe. Our contention is that there isn’t an acceptable view of ideally rational belief given the assumptions of the open future and retro-closure, and thus this casts doubt on the conjunction of those assumptions.

This book launches a sustained defense of a radical interpretation of the doctrine of the open future. Patrick Todd argues that all claims about undetermined aspects of the future are simply false.

It is widely accepted that there is what has been called a non-hypocrisy norm on the appropriateness of moral blame; roughly, one has standing to blame only if one is not guilty of the very offence one seeks to criticize. Our acceptance of this norm is embodied in the common retort to criticism, “Who are you to blame me?”. But there is a paradox lurking behind this commonplace norm. If it is always inappropriate for x to blame y for a (...) wrong that x has committed, then all cases in which x blames x (i.e. cases of self-blame) are rendered inappropriate. But it seems to be ethical common-sense that we are often, sadly, in position (indeed, excellent, privileged position) to blame ourselves for our own moral failings. And thus we have a paradox: a conflict between the inappropriateness of hypocritical blame, and the appropriateness of self-blame. We consider several ways of resolving the paradox, and contend none is as defensible as a position that simply accepts it: we should never blame ourselves. In defending this startling position, we defend a crucial distinction between self-blame and guilt. (shrink)

We often ascribe possibility to the scenes that are displayed by mental or nonmental sensory images. The paper presents a novel argument for thinking that we are prima facie justified in ascribing metaphysical possibility to what is displayed by suitable visual images, and it argues that many of our imagery‐based ascriptions of metaphysical possibility are therefore prima facie justified. Some potential objections to the arguments are discussed, and some potential extensions of them, to cover nonvisual forms of imagery and nonmetaphysical (...) forms of possibility, are endorsed.

This paper offers a new approach to an old debate about superaddition in Locke. Did Locke claim that some objects have powers that are unrelated to their natures or real essences? The question has split commentators. Some (Wilson, Stuart, Langton) claim the answer is yes and others (Ayers, Downing, Ott) claim the answer is no. This paper argues that both of these positions may be mistaken. I show that Locke embraced a robust epistemic humility. This epistemic humility includes ignorance of (...) the real essences of bodies, of the causal processes underlying the production of natural phenomena, and of God’s method of creation. I show how this epistemic humility offers strong support for an agnostic response to the question of superaddition. Locke did not intend to claim that bodies either do or do not have properties unrelated to their real essences. Instead, his primary goal in discussing the topic was to emphasize the strict limits to human knowledge. (shrink)

Management and Morality provides a comprehensive and accessible overview of the moral and ethical dimension to organizational and individual behavior, while adding an original, developmental perceptive. Management and Morality combines organizational theory and behavior with approaches to organizational and individual development. The first two sections of the book, Ethical Thinking and Management Practice, and Moral Issues in Organizations, provide a clear and thorough coverage of these areas relevant to ethical behavior in and of organizations. On this basis, the third section, (...) A Developmental Perspective, develops a new approach to ethical development of organizations and individuals concerned with the improvement of organizational structures, processes, and practices so as to allow for individual morality and individual moral behavior. Rich in its coverage of the field and variety of ideas, Management and Morality will be essential reading to students and academics in management, business and organizational ethics, organizational behavior and development, and organizational sociology.

This introduction to modern work in analytic philosophy uses the example of the proper name to give a clear explanation of the logical theories of Gottlob Frege, and explain the application of his ideas to ordinary language. McCulloch then shows how meaning is rooted in the philosophy of mind and the question of intentionality, and looks at the ways in which thought can be "about" individual material objects.
