Ambiguity has an important and often essential role to play in all areas of meaningful thought, expression, and claims to truth. Amicable Ambiguity explores areas of thought and experience where conceptual and discursive ambiguity can be the amicable friend of intelligibility and convincingness rather than their sworn enemy.

The idea that ambiguity can be productive in data science remains controversial. Efforts to make scientific publications and data intelligible to computers generally assume that accommodating multiple meanings for words, known as polysemy, undermines reasoning and communication. This assumption has nonetheless been contested by historians, philosophers, and social scientists, who have applied qualitative research methods to demonstrate the generative and strategic value of polysemy. Recent quantitative results from linguistics have also shown how polysemy can actually improve the efficiency of (...) human communication. I present a new conceptual typology based on a synthesis of prior research about the aims, norms, and circumstances under which polysemy arises and is evaluated. The typology supports a contextual pluralist view of polysemy’s value for scientific research practices: polysemy does both substantial positive and negative work in science, but its utility is context-sensitive in ways that are often overlooked by the norms people have formulated to regulate its use, including prior scholars researching polysemy. I also propose that historical patterns in the use of partial synonyms, i.e. terms with overlapping meanings, provide an especially promising phenomenon for integrative research addressing these issues.

Imprecise Bayesianism has been proposed as an alternative to Standard Bayesianism, partly because of its tools for representing ambiguity. Instead of representing credences via precise probabilities, a set of probability distributions is used to model belief states. However, there are criticisms of Imprecise Bayesianism’s update rule. A recent alternative update rule is Alpha Cut, which evades some of the primary criticisms of Imprecise Bayesian updating. We compare Alpha Cut with Imprecise Bayesianism and another alternative update approach called Calibration. We (...) find that Alpha Cut has problems with respect to ambiguity, coherence, and performance qualities, whereas there are more promising alternatives. (shrink)

A family of familiar linguistic tests purport to help identify when a term is ambiguous. These tests are philosophically important: a familiar philosophical strategy is to claim that some phenomenon is disunified and its accompanying term is ambiguous. The tests have been used to evaluate disunification proposals about causation, pain, and knowledge, among others. -/- These ambiguity tests, however, have come under fire. It has been alleged that the tests fail for polysemy, a common type of ambiguity, and (...) one that is at issue in philosophically interesting cases. Furthermore, the objection that the tests fail for polysemy is often taken to be an undeniable bit of linguistic data. -/- We argue that this is mistaken. The objection implicitly relies on controversial assumptions about how to account for copredicational sentences, in which a single argument is ascribed prima facie incompatible properties. Furthermore, on several viable theories of copredication, the objection fails. However, our discussion also reveals that even if ambiguity tests are preserved, they may be significantly harder to execute than previously thought. (shrink)

In arguing against a supposed ambiguity, philosophers often rely on the zeugma test. In an application of the zeugma test, a supposedly ambiguous expression is placed in a sentence in which several of its supposed meanings are forced together. If the resulting sentence sounds zeugmatic, that is taken as evidence for ambiguity; if it does not sound zeugmatic, that is taken as evidence against ambiguity. The aim of this article is to show that arguments based on the (...) second direction of the test are misguided: ambiguous expressions, and in particular philosophically contested ones, do not reliably lead to zeugmaticity, so an absence of zeugmaticity provides no meaningful evidence for an absence of ambiguity.

In this contribution to the Common Knowledge symposium “Fuzzy Studies: On the Consequence of Blur,” the words ambiguity, ambivalence, and ambience are shown to share the common prefix, from Latin, ambi-, defined in most modern dictionaries as “around, on both sides.” Ambi captures some, but not all, so Leo Spitzer has argued, of the multiple senses (physical surrounding, spiritual embrace, air) that Greeks infused into the prefix peri. Ambiguity and ambience (“going around,” “that which surrounds”), as well as (...) the more modern ambivalence (coined in the context of psychonanalysis), suggest different angles of perception, but all represent fuzzy modes, modes that would seem to have no place in science, especially in climate science, which is pressed to be ever more precise. Yet an analysis of the genealogy of these terms and, in particular, of the differential relation between “around” and “on both sides” may reveal that the very fuzziness of ambi is precisely what is required to grasp the chaotic complexity of the environment.

Representationalism is the position that the phenomenal character of an experience is either identical with, or supervenes on, the content of that experience. Many representationalists hold that the relevant content of experience is nonconceptual. I propose a counterexample to this form of representationalism that arises from the phenomenon of Gestalt switching, which occurs when viewing ambiguous figures. First, I argue that one does not need to appeal to the conceptual content of experience or to judgements to account for Gestalt switching. (...) I then argue that experiences of certain ambiguous figures are problematic because they have different phenomenal characters but that no difference in the nonconceptual content of these experiences can be identified. I consider three solutions to this problem that have been proposed by both philosophers and psychologists and conclude that none can account for all the ambiguous figures that pose the problem. I conclude that the onus is on representationalists to specify the relevant difference in content or to abandon their position. (shrink)

Coherent-ambiguity aversion is defined within the smooth-ambiguity model as the combination of choice-ambiguity and value-ambiguity aversion. Five ambiguous decision tasks are analyzed theoretically, where an individual faces two-stage lotteries with binomial, uniform, or unknown second-order probabilities. Theoretical predictions are then tested through a 10-task experiment. In tasks 1–5, risk aversion is elicited through both a portfolio choice method and a BDM mechanism. In tasks 6–10, choice-ambiguity aversion is elicited through the portfolio choice method, while value- (...) class='Hi'>ambiguity aversion comes about through the BDM mechanism. The behavior of over 75 % of classified subjects is in line with the KMM model in all tasks 6–10, independent of their degree of risk aversion. Furthermore, the percentage of coherent-ambiguity-averse subjects is lower in the binomial than in the uniform and in the unknown treatments, with only the latter difference being significant. The most part of coherent-ambiguity-loving subjects show a high risk aversion. (shrink)

We use probability-matching variations on Ellsberg’s single-urn experiment to assess three questions: (1) How sensitive are ambiguity attitudes to changes from a gain to a loss frame? (2) How sensitive are ambiguity attitudes to making ambiguity easier to recognize? (3) What is the relation between subjects’ consistency of choice and the ambiguity attitudes their choices display? Contrary to most other studies, we find that a switch from a gain to a loss frame does not lead to (...) a switch from ambiguity aversion to ambiguity neutrality and/or ambiguity seeking. We also find that making ambiguity easier to recognize has little effect. Finally, we find that while ambiguity aversion does not depend on consistency, other attitudes do: consistent choosers are much more likely to be ambiguity neutral, while ambiguity seeking is much more frequent among highly inconsistent choosers.

The veil of ignorance argument was used by John C. Harsanyi to defend Utilitarianism and by John Rawls to defend the absolute priority of the worst off. In a recent paper, Lara Buchak revives the veil of ignorance argument, and uses it to defend an intermediate position between Harsanyi's and Rawls' that she calls Relative Prioritarianism. None of these authors explore the implications of allowing that agent's behind the veil are averse to ambiguity. Allowing for aversion to ambiguity---which (...) is both the most commonly observed and a seemingly reasonable attitude to ambiguity---however supports a version of Egalitarianism, whose logical form is quite different from the theories defended by the aforementioned authors. Moreover, it turns out that the veil of ignorance argument neither supports standard Utilitarianism nor Prioritarianism unless we assume that rational people are insensitive to ambiguity. (shrink)

_The Ambiguity of Justice_ consists of a collection of essays that address difficulties and potential contradictions in thinking justice by focussing on Ricoeur's theory of justice and on the major thinkers that were influential for it.

Incomplete information is a commonly cited barrier to the adoption of new innovations. We present a decision-making experiment, conducted with farmers in the field, that explores the extent to which information which reduces ambiguity may be provided as a public good. In the experiment, participants make a series of decisions between a risky gamble and an ambiguous gamble. An initial private decision is followed by second choice in which participants know that their chosen gambles and outcomes will be publicly (...) but anonymously revealed. Selection of the ambiguous option in this decision thus provide public good information which can be used to update beliefs about the ambiguous gamble. After the public revelation, participants make one final choice between the two options which we use to assess learning. We also test communication as a mechanism to increase provision of the public good. We find evidence that people with preference to avoid ambiguity contribute to public good information while risk averse people free ride. Communication does not affect the overall public good provision, either in a positive or negative direction. Finally, we find that people draw appropriate inference from the information that the public good provides. We relate our findings to the issue of new technology adoption in agriculture which is of particular importance for our participants. (shrink)

Macpherson (Nous 40(1):82–117, 2006) argues that the square/regular diamond figure threatens representationalism, construed as the theory which holds that the phenomenal character is explained by the nonconceptual content of experience. Her argument is the claim that representationalism is committed to the thesis that differences in the experience of ambiguous figures, the gestalt switch, should be explained by differences in the NCC of perception of these figures. However, with respect to the square/regular diamond and some other ambiguous figure representationalism fails to (...) offer a unified account of how representational content makes them ambiguous. In this paper, I aim, first, to offer a representationalist account of ambiguous figures and, second, to examine and rebut Macpherson’s arguments. My main point is that in each ambiguous figure Macpherson discusses there are differences in representational content that can explain differences in phenomenal character or content. The representational differences are due to the ways the Cartesian frame of reference in which perceptual content is always cast cuts the figure, underlying different properties of the figure with respect to the axes of the Cartesian frame of reference.

Tacitly authorized unauthorized immigrants are officially unauthorized, but their presence is tacitly sanctioned by the state because of the economic or political benefits their presence provides. Most arguments about them claim they have a moral right to remain because the state is complicit in their presence. This complicity argument, however, is fundamentally flawed because it suggests there is nothing inherently unjust about the practice of tacitly authorizing unauthorized immigrants. This article argues that states commit an injustice when they tacitly authorize (...) unauthorized immigrants because it socially constructs them in a way that uniquely and unjustly undermines their planning agency. To make this claim I introduce a novel form of injustice, what I call ontological ambiguity, which occurs when an individual is socially constructed as a member of two social kinds simultaneously and the individual experiences the constraints and enablements constitutive of both social kinds as incompatible. I show that tacitly authorized unauthorized immigrants are necessarily socially constructed as ontologically ambiguous and then argue that recognizing the injustice of ontological ambiguity reveals a more compelling argument regarding their rights: while it may not establish a right to remain, it does entail that states are morally prohibited from tacitly authorizing unauthorized immigrants.

This paper argues that questionable research practices, such as data "mining" or inappropriate authorship, have important implications for an understanding of the scientific process. Gray areas in research conduct reflect ambiguities or inconsistencies among three types of research standards: common practice, technical issues, and ethical principles. An analysis of questionable conduct requires explicit attention to the ethics of common research practices.

Macpherson (2006) argues that the square/regular diamond figure threatens representationalism, which holds that the phenomenal character of experience is either identical, or supervenes on, the nonconceptual content of experience (NCC). Her argument is that representationalism is committed to the thesis that differences in the phenomenal experience of ambiguous figures, the gestalt switch, should be explained by differences in the NCC of perception of these figures. However, with respect to the square/regular diamond figure such differences in NCC do not explain the (...) gestalt switch. I examine Macpherson’s claims and argue that representationalism can account for the experience of ambiguous figures by explaining differences in the phenomenal content of experience by means of differences in the NCC of that same experience. The thrust of my argument is that Macpherson’s account of what happens when subjects, upon viewing a tilted A and an A, report their experience by using the concept-term “A”, mistakes seeph with seedox. If this confusion is cleared, then representationalism can offer a coherent account of the gestalt switch in the diamond/square figure on the basis of the NCC of that experience. (shrink)

In his reflections on action in Being and Nothingness, Sartre goes to the heart of what it is to be human. Our free actions are not the consequence of ouridentity, they are its foundation. As human beings we go beyond who we are towards a freely chosen future self. Human identity is ambiguous because consciousness simultaneously accepts and sees beyond the identity it discovers; there is an internal disintegration which distances us from ourselves. The intentionality of consciousness means that we (...) are constituted not by an objective presence but by a “presence to” our identity. Personhood is established only when we select certain values and allow them to shape our identity and guide our actions. As “being-for-itself” we go beyond the present and project ourselves towards an identity that does not yet exist, thus creating ourselves through our freedom, through our concrete choices. This article pays careful attention to Sartre’s understanding of consciousness, selfconsciousness, and “selfness,” before drawing some conclusions about the role of human freedom in the construction of identity.

This book argues that history may, by definition, be an imperialist science or a quintessentially Western form of discourse. Finn Fuglestad thinks there is something profoundly ambiguous about the science or academic discipline we call history. It is the only science that is the product of its own object of study, the past, an object outside of which it cannot exist. It is also the only science that can study itself. The author argues that history has a relationship with one (...) of the so-called civilizations of the world that borders on the incestuous. That civilization is Western Civilization: history has both emerged from it and helped to shape it in such a way that they are inextricably linked. History, with its Western conceptual framework, has become a defining part of Western Civilization to the extent that the West cannot even conceive of itself being without history. But what happens when history is removed from its natural habitat? Can it be done, and has it been done, other than on the terms of the West? The real issue therefore concerns all those societies and peoples outside the West who, in accordance with the Hegelian tradition, have traditionally been labeled as without history. What does it mean exactly not to have history? The reconstruction of the pasts of peoples without history poses a tremendous challenge to the science of history, especially at the conceptual level. Finn Fuglestad not only believes that there has been a failure to confront this challenge properly, but he also questions whether anything can really be done. (shrink)

Drawing on 171 in-depth interviews with physicists at universities in the United States and the UK, this study examines the narratives of 48 physicists to explain the concept of ethical ambiguity: the border where legitimate and illegitimate conduct is blurred. Researchers generally assume that scientists agree on what constitutes both egregious and more routine forms of misconduct in science. The results of this study show that scientists perceive many scenarios as ethically gray, rather than black and white. Three orientations (...) to ethical ambiguity are considered—altruism, inconsequential outcomes, and preserving the status quo—that allow possibly questionable behavior to persist unchallenged. Each discursive strategy is rationalized as promoting the collective interest of science rather than addressing what is ethically correct or incorrect. The results of this study suggest that ethics training in science should focus not only on fabrication, falsification, and plagiarism and more routine forms of misconduct, but also on strategies for resolving ethically ambiguous scenarios where appropriate action may not be clear.

The paper examines the status of ambiguity in the thought of Plotinus (c. 204/205-270). Even though ambiguity should be regarded as the enemy of the philosopher and as pertaining rather to the rhetorical tradition and not the philosophical one as it was especially established by Plato and Aristotle, one can argue that the particularly Neoplatonist philosophical project permitted an important place to it due to some fundamental inherent aspects that it contained. Most importantly, the ambiguity in the (...) generation of the Intellect from the One is examined in this paper as related to the dialectic between existence and being. In such a perspective, ambiguity is initiated by the fact that being is both one in order to exist and not one in order to be a being. Thus, it can be explained only in dialectic with an ontological reality beyond it, namely an absolute One. This means that, in turn, its generation as Intellect from the latter is necessarily a two-fold movement: Both a distribution of existence by procession and a reverting contemplative act for acquisition of substantial definition. This dialectic does not only concern the highest ontological level of the relation of the Being to the One, but is a permanent ontological vacillation in the system of Plotinus. The paper observes this valorization of ambiguity as an original and dynamic feature of Plotinian ontology that arguably paved the way for Modernity. (shrink)

In this paper, I apply Graham Priest’s logical critique of the cosmological argument to the Kalām Cosmological Argument (KCA), focusing on a key ambiguity in its first premise: “Whatever begins to exist has a cause.” When formalized in first-order predicate logic (FOL), this premise admits two non-equivalent interpretations. One of which allows for multiple distinct causes while another posits a single universal cause. This logical ambiguity reveals a limitation of FOL in expressing metaphysical claims with the necessary precision. (...) By extension, this ambiguity undermines the structural coherence of the KCA when expressed in FOL. My central aim is not to refute the KCA’s conclusion but to demonstrate that its first-order formulation lacks logical determinacy. To address this, I develop a second-order modal logical (SOML) framework that incorporates functional mappings, uniqueness constraints, and metaphysical necessity. This revised formalism eliminates the ambiguity while preserving the KCA’s philosophical commitments. (shrink)

The orthodox view of proper names, Millianism, provides a very simple and elegant explanation of the semantic contribution of referential uses of names–names that occur as bare singulars and as the argument of a predicate. However, one problem for Millianism is that it cannot explain the semantic contribution of predicative uses of names. In recent years, an alternative view, so-called the-predicativism, has become increasingly popular. According to the-predicativists, names are uniformly count nouns. This straightforwardly explains why names can be used (...) predicatively, but is prima facie less congenial to an analysis of referential uses. To address this issue, the-predicativists argue that referential names are in fact complex determiner phrases consisting of a covert definite determiner and a count noun—and so, a referential name is a definite description. In this paper, I will argue that despite the appearance of increased theoretical complexity, the view that names are ambiguous between predicative and referential types is in fact superior to the unitary the-predicativist view. However, I will also argue that to see why this ambiguity view is better, we need to give up the standard Millian analysis. Consequently, I will first propose an alternative analysis of referential names that retains the virtues of Millianism, but provides an important explanatory connection to the predicative uses. Once this analysis of names is adopted, the explanation for why names are systematically ambiguous between referential and predicative types is both simple and elegant. Second, I will argue that the-predicativism has the appearance of being simpler than an ambiguity view, but is in fact unable to account for certain key properties of referential names without making ad hoc stipulations.

This volume uncovers a great mystery about language: why can we communicate so effectively despite the fact that ambiguity is pervasive? Conversely, how do speakers use ambiguity to achieve a specific goal? Answers to these questions are provided from different fields: linguistics, literary criticism, rhetoric, theology, media studies, law.

Through a series of empirical studies involving native speakers of English, German, and Chinese, this paper reveals that the predicate “true” is inherently ambiguous in the empirical domain. Truth statements such as “It is true that Tom is at the party” seem to be ambivalent between two readings. On the first reading, the statement means “Reality is such that Tom is at the party.” On the second reading, the statement means “According to what X believes, Tom is at the party.” (...) While there appear to exist some cross-cultural differences in the interpretation of the statements, the overall findings robustly indicate that “true” has multiple meanings in the realm of empirical matters.

It is one of the paradoxes of our age that the 'success' of democracy in Eastern Europe and South Africa is coupled with grave disappointment in the 'birth places' of modern democracy. This dis appointment is partly due to the irreducible ambiguity entailed in democratic institutional arrangements. Democracy, in fact, is founded on this ambiguity. It attempts to construct social unity on the basis of recognizing the lack around which the social field is always structured. In that sense (...) the source of the disappointment caused by democracy is of an ethical status. It is the antithesis between the ambiguity of democracy and a still hegemonic ethics of harmony. Any aspiration, however, to eliminate the ambiguity of democracy ignores the innovative logic of democratic politics. If the ethics of harmony lead to a de-democratization of democracy, what a radical democratic project needs today is an ethical basis of a totally different nature. Here, the ethics of psychoanalysis, as formulated in the Lacanian tradition, can be of great help. Key Words: democracy • ethics • harmony • Lacan • psychoanalysis. (shrink)

ABSTRACT This paper investigates how pronouns were used by UK government speakers to allocate responsibility to themselves and others in all 92 daily televised COVID-19 briefings that were held between March and June 2020. We identified the referent for every use of the first-person plural pronoun (1PL) as ‘inclusive’, ‘exclusive’, or 'ambiguous' and analysed the transitivity patterns in which these pronouns act as Participants. We argue that the UK government uses the inherent ambiguity of this pronoun to strategically mitigate (...) their own responsibility for controlling the spread of the virus, while increasing the amount of responsibility to the general public. In doing so, we propose a transparent and replicable systematic method for identifying the referents of pronouns, which may be useful to other discourse analysts faced with the challenging task of pronoun resolution.

Research on interpersonal trauma tends to focus on the effects of traumatic encounters on those one who directly undergo the experience. In this paper, I seek to understand the experiences of the friends and family of the one who has undergone trauma, a paradigmatic case being the relatives of veterans (O’Nell, 1999). I argue that one way we can understand the experiences of friends and relatives is through Pauline Boss’ concept of _ambiguous loss_ (Boss, 1986, 2007). The kind of ambiguous (...) loss relevant for our purposes is when a family member is physically present but psychologically absent, for example, in the case of a relative with advanced dementia. This is what I purport happens in some instances of traumatic experience. I argue that third-person traumatic encounter can be experienced as a loss due to the changes in the person who has undergone the traumatic encounter and that this, in turn, causes changes in the person experiencing the loss and their relationship with their traumatised family member. I argue that first-person traumatic encounter is a transformative experience (Paul, 2014), i.e., an experience which causes personal and epistemic changes in the subject undergoing it, and that third-person traumatic encounter can also be a transformative experience.

Hegemonic practices of memorialization rely on narratives of heroic, morally untainted resistance, which cast traitors as the aberrant “other.” This paper draws on Simone de Beauvoir’s The Ethics of Ambiguity and historical and sociological accounts of betrayal to trouble this binary and construct a framework for memorializing betrayal in its ambiguity—in relation to the everyday reality of tragic dilemmas that resisters face. I show how attentiveness to the ambiguity of betrayal can help rethink heroic resistance myths beyond (...) the exclusionary logic pitting moral purity against the depravity of treason—and warn against the reproduction of systematic practices of othering in the new political order. The paper develops the political relevance of this theoretical exploration via the example of a South African novel, The Texture of Shadows, examining how its insights into the ambiguity of betrayal challenge the myths of heroic resistance in South Africa.

Pragmatic Ambiguity: The Thetic Function of ModalityThe aim of this paper is to present an overview of the pragmatic aspects of ambiguity present in deontic sentences, which may have three pragmatic functions: a prescriptive or a descriptive or a constitutive function. This type of ambiguity is investigated on the lexical, phrasal, and sentential level. The discussion focuses on the deontic constructions of the German verb sollen and the English shall as they are used in legal texts. It (...) also includes comments on the thetic function of the Latin imperative mood and the subjunctive mood. (shrink)

The ambiguity theory of “knows” is the view that knows and its cognates have more than one propositional sense—i.e., more than one sense that can properly be used in “knows that” etc. constructions. The ambiguity theory of “know” has received relatively little attention as an account of the truth-conditions for knowledge ascriptions and denials—especially compared to views like classical, moderate invariantism and epistemic contextualism. In this paper, it is argued that the ambiguity theory of knows has an (...) advantage over both classical, moderate invariantism and epistemic contextualism. This advantage is that it is the only one of these views that can account for “diverging knowledge responses without inconsistency” —i.e., cases in which, for the same subject S and proposition p, one and the same speaker says truly “S knows p” but instead could have truly said “S does not know p” and vice versa. This paper argues both for the existence of DRWI scenarios and the ability of the ambiguity theory of knows to best explain their existence. (shrink)

Abstract Theories of descriptions tend to involve commitments about the ambiguity of descriptions. For example, sentences containing descriptions are widely taken to be ambiguous between de re , de dicto , and intermediate interpretations and are sometimes thought to be ambiguous between the former and directly referential interpretations. I provide arguments to suggest that none of these interpretations are due to ambiguities (or indexicality). On the other hand, I argue that descriptions are ambiguous between the above family of interpretations (...) and what may be called ‘institutional’ as well as generic interpretations. My arguments suggest that an adequate theory of descriptions may require considerable rethinking. Most contemporary theories of descriptions appear to be committed to one or more claims about the ambiguity of descriptions that I reject in this paper. I suggest that my observations provide a reason to renew efforts to develop a theory of descriptions within a representationalist theory of interpretation.

Considerations of dynamic inconsistency have figured prominently in debates over the rationality of preferences that violate the separability conditions characteristic of expected utility theory. These debates have mostly focused on risk- and ambiguity averse preferences, but analogous considerations apply to preferences for fairness. We revisit these debates in the context of a specific hypothesis regarding the violations of separability by such preferences, namely that they are potentially both explained and rationalised by attitudes to the chances of goods that motivate (...) a preference for equality in the distribution of chances across people and possible events. Our main aim is to argue that, first, when these violations of static separability are motivated by such attitudes to chances, then they need not result in dynamically inconsistent behaviour. Second, and more generally, considerations of dynamic consistency do not, we argue, undermine the rationality of such attitudes towards the distribution of chances, despite the fact that such attitudes give rise to violations of the static separability assumptions of expected utility theory.

Ambiguous figures pose a problem for representationalists, particularly for representationalists who believe that the content of perceptual experience is non-conceptual (MacPherson in Nous 40(1):82–117, 2006). This is because, in viewing ambiguous figures, subjects have perceptual experiences that differ in phenomenal properties without differing in non-conceptual content. In this paper, I argue that ambiguous figures pose no problem for non-conceptual representationalists. I argue that aspect shifts do not presuppose or require the possession of sophisticated conceptual resources and that, although viewing ambiguous (...) figures often causes a change in phenomenal properties, this change is accompanied by a change in non-conceptual content. I illustrate the case by considering specific examples. (shrink)

For social species, having strong and high-quality social relationships is an important safety cue. Loneliness occurs when an individual perceives they have insufficient relationships resulting in feelings of lack of safety. States of perceived unsafety are linked to an increased tendency to construe ambiguous information – information lacking a unique clear interpretation – as threatening. Here, we explore whether the ambiguity of social cues of interpersonal rejection moderates effects of loneliness on feelings of rejection while undergoing social exclusion. Data (...) were collected in 2021; 144 adults completed a progressive social exclusion paradigm where they were randomly assigned to be equally included, excluded, or over-included. Social exclusion/inclusion cues became more pronounced over the course of multiple rounds of a ball-tossing game (Cyberball) resulting in a scenario where ambiguity was highest in earlier rounds and decreased over time. Participants reported feelings of loneliness prior to the task and feelings of rejection throughout the task. Results demonstrated that higher loneliness predicted increased feelings of rejection regardless of exclusion condition. Notably, this positive relationship was strongest during earlier rounds when social cues were most ambiguous. These findings contribute to our understanding of how loneliness modulates social perception to enable organisms to adequately adapt to changing circumstances. (shrink)

For Hannah Arendt, authority is the shape educational responsibility assumes. In our time, authority in Arendt’s sense is under pressure. The figure of Greta Thunberg shows the failure of adult generations, taken collectively, to take responsibility for the world and present and future generations of newcomers. However, in reflecting on Arendt’s use of authority, we argue that her account of authority also requires amendments. Arendt’s situating of educational authority in-between past and future adequately captures its temporal dimension. We make explicit (...) another, spatial, dimension: authority in-between world and earth. Arendt’s neglect of the material earth also has implications for the relational dimension of authority. Arendt’s authority depends on a dichotomy between the private and the public sphere. This is problematic. First, we agree with Arendt’s feminist critics that the personal can be made into the site of the political. Second, we point once more to Thunberg, the child, taking the public stage, thereby contesting the division between public and private. In response, we situate the relational dimension of authority in-between private and public. The three dimensions of educational authority taken together imply that it is situated in-between domains that cannot be reduced to each other or taken as absolutes: past and future, world and earth, and the private and public sphere. This brings us to our concept of ambiguous authority, which expresses the Arendtian nature of our reflections and the ways in which we seek to renew her original insights on educational authority.

Ambiguous Adventure, one of the most iconic novels in Senegalese history, recounts the plight of a traditional African society in the face of an encroaching western modernity, with its main character, Samba Diallo, as the face of this momentous struggle. The captivating story inspired numerous critiques that address the text from sociological, religious, and philosophical perspectives. Not surprisingly, most of the interpretations are based on the textual connection to Islam, the religion embraced and practiced by the Diallobé community in the (...) novel, and deal with universal topics such as death, identity, colonialism, initiation, tradition, and modernity. Building on the work done before me on Samba’s own search for identity within the Muslim context, I look to pre-Islamic Fulani traditions articulated by Amadou Hampaté Bâ, which better illuminate the process of initiation that leads the human being to transform into a self-realized person. I argue, based on this Fulani metaphysical context, that from the very beginning, Samba Diallo’s journey is initiatic in itself, in the traditional Fulani conception of the term, one that is connected to the sacred dimension. In this sense, the Fulani indigenous traditions anticipate Samba’s journey toward a sacred identity, highlight a clear roadmap to that very process, and, contrary to many critics, lead the initiate to success.

This article shows that Thucydides is deliberately enigmatic about the causal effects of his speeches, and that this enigma is central to understanding his account of the outbreak of the Peloponnesian War. First, it shows that Thucydides was fascinated by the way speeches might not only illuminate events but also contribute to causing them. This ambiguous aspect of the speeches has been underappreciated in recent scholarship, but it is a theme to which the historian frequently returns. Second, the article shows (...) that Thucydides explores this ambiguity in particular detail through the debates in Book 1. Using echoes of the “truest explanation” from 1.23.6 in the speeches, Thucydides suggests that the war might have started through a process of self-fulfilling prophecy, rather than—as some recent scholarship has suggested—self-fulfilling perception. Finally, this article suggests a new reading of 1.23.6, which reflects the ambiguous nature of the speeches in the ambiguous term πρόφασις, again hinting at the possibility of a self-fulfilling prophecy. This article therefore challenges not only the idea of the “Thucydides Trap,” which continues to dominate conceptions of Thucydides among political scientists, but also the way all readers of his work approach both Book 1 and the role of the speeches in general.

Ambiguity associated with everyday practice of science has made it difficult to reach a consensus on how to define misconduct in science. This essay outlines some of the important ambiguities of practice such as distinguishing data from noise, deciding whether results falsify a hypothesis, and converting research into research publications. The problem of ambiguity is further compounded by the prior intellectual commitments inherent in choosing problems and in dealing with the skepticism of one's colleagues. In preparing a draft (...) code of ethics for the American Society of Biochemistry and Molecular Biology (ASBMB), an attempt was made to take into account the ambiguities of practice. Also, the draft code adopted trust as its leading principle, specifically the importance of trust as a condition necessary for there to be science. During revision of the code, the focus on trust was changed. The new orientation was on trust as a consequence of carrying out science responsibly. By addressing the obligations necessary to engender trust, the ASBMB ethics code not only sets professional standards, but also makes a clear statement of public accountability. (shrink)

Daniel Ellsberg presented in Ellsberg (The Quarterly Journal of Economics 75:643–669, 1961) various examples questioning the thesis that decision making under uncertainty can be reduced to decision making under risk. These examples constitute one of the main challenges to the received view on the foundations of decision theory offered by Leonard Savage in Savage (1972). Craig Fox and Amos Tversky have, nevertheless, offered an indirect defense of Savage. They provided in Fox and Tversky (1995) an explanation of Ellsberg’s two-color problem (...) in terms of a psychological effect: ambiguity aversion. The ‘comparative ignorance’ hypothesis articulates how this effect works and explains why it is important to an understanding of the typical pattern of responses associated with Ellsberg’s two-color problem. In the first part of this article we challenge Fox and Tversky’s explanation. We present first an experiment that extends Ellsberg’s two-color problem where certain predictions of the comparative ignorance hypothesis are not confirmed. In addition the hypothesis seems unable to explain how the subjects resolve trade-offs between security and expected pay-off when vagueness is present. Ellsberg offered an explanation of the typical behavior elicited by his examples in terms of these trade-offs and in section three we offer a model of Ellsberg’s trade-offs. The model takes seriously the role of imprecise probabilities in explaining Ellsberg’s phenomenon. The so-called three-color problem was also considered in Fox and Tversky (1995). We argue that Fox and Tversky’s analysis of this case breaks a symmetry with their analysis of the two-color problem. We propose a unified treatment of both problems and we present a experiment that confirms our hypothesis. (shrink)

Wakker (Theory Decis 29:119–132, 1990) proved that the rank-dependent utility model is a special case of Choquet expected utility model. Invoking this result and applying the certainty equivalent reduction procedure, this paper shows that risk aversion in the rank-dependent utility model implies ambiguity aversion in the corresponding Choquet expected utility model. Consequently, the pattern of choice depicted by Ellsberg’s experiments and, more generally, preference for evidence to support their beliefs is an expression of decision makers’ risk aversion. In addition, (...) the paper introduces a new procedure of updating capacities by the application of Bayes rule that smooth ambiguity aversion may also be regarded as risk aversion. (shrink)

The use of ambiguous expressions in argumentative dialogues can lead to misunderstanding and equivocation. Such ambiguities are here called active ambiguities . However, even a normative model of persuasion dialogue ought not to ban active ambiguities altogether, one reason being that it is not always possible to determine beforehand which expressions will prove to be actively ambiguous. Thus, it is proposed that argumentative norms should enable each participant to put forward ambiguity criticisms as well as self-critical ambiguity corrections, (...) inducing them to improve their language if necessary. In order to discourage them from nitpicking and from arriving at excessively high levels of precision, the parties are also provided with devices with which to examine whether the ambiguity corrections or ambiguity criticisms have been appropriate. A formal dialectical system is proposed, in the Hamblin style, that satisfies these and some other philosophical desiderata. (shrink)

Freud proposes that in unconscious processing, logical connections are also (heavily) based upon phonological similarities. Repressed concerns, for example, would also be expressed by way of phonologic ambiguity. In order to investigate a possible unconscious influence of phonological similarity, 31 participants were submitted to a tachistoscopic subliminal priming experiment, with prime and target presented at 1ms. In the experimental condition, the prime and one of the 2 targets were phonological reversed forms of each other, though graphemically dissimilar (e.g., “nice” (...) and “sign”); in the control condition the targets were pseudo-randomly attributed to primes to which they don’t belong. The experimental task was to “blindly” pick the choice most similar to the prime. ERPs were measured with a focus on the N320, which is known to react selectively to phonological mismatch in supraliminal visual word presentations. The N320 amplitude-effects at the electrodes on the midline and at the left of the brain significantly predicted the participants’ net behavioral choices more than half a second later, while their subjective experience is one of arbitrariness. Moreover, the social desirability score (SDS) significantly correlates with both the behavioral and the N320 brain responses of the participants. It is proposed that in participants with low SDS the phonological target induces an expected reduction of N320 and this increases their probability to pick this target. In contrast, high defensive participants have a perplexed brain reaction upon the phonological target, with a negatively peaking N320 as compared to control and this leads them to avoid this target more often. Social desirability, which is understood as reflecting defensiveness, might also manifest itself as a defense against the (energy-consuming) ambiguity of language. The specificity of this study is that all of this is happening totally out of awareness and at the level of very elementary linguistic distinctions. (shrink)

As the content of propositional attitudes, propositions are usually taken to help explain the behavior of rational agents. However, a closer look at signaling games suggests otherwise: rational agents often acquire partial beliefs, and many of their signals are ambiguous. Signaling games also suggest that it is rational for agents to mix their behavior in response to partial beliefs and ambiguous signals. But as I show in this paper, propositions cannot help explain the mixing behavior of rational agents: to explain (...) mixing behavior, we need a probabilistic notion of content. I also show that a probabilistic notion of content renders propositions explanatorily idle in the case of unambiguous signals and full beliefs as well. My suggestion is thus that we should abandon propositions in explanations of rational behavior and adopt instead a probabilistic notion of content. The notion of probabilistic content ultimately provides a simpler framework for explanations of rational behavior than the notion of propositional content. (shrink)

Each thinker, according to Heidegger, essentially thinks one thought. Plato thinks the idea. Descartes thinks the cogito . Spinoza thinks substance. Nietzsche thinks the will to power. If a thinker does not think a thought, then he or she is not a thinker. He or she may be a scholar or a professor, a producer or a consumer, a fan or a fake, but he or she would not be a thinker. Thus, if Heidegger is a thinker, he essentially thinks (...) one thought. What is Heidegger’s one thought? It is neither life nor death, neither me nor you. It is neither technology nor art. It is neither spirit nor language. Heidegger’s one thought is being—or more precisely, the question of the meaning of being. And what is being? Neither presence nor absence--but rather, an ambiguous uncertainty. (shrink)

The distinction between constitutive and regulative rules is applied to rules for critical discussion that have to do with the use of ambiguous expressions. This leads to a distinction between rule violating fallacies, by which one abandons a critical discussion, and norm violating fallacies, which are in a way admissible within a critical discussion. According to the formal model for critical discussion, proposed in this paper, fallacies of the norm violating type arc not prohibited. Instead, it provides discussants with devices (...) to discuss fallacies and fallacy criticisms. (shrink)
