Let ℰΠ denote the collection of all Π01 classes, ordered by inclusion. A collection of Turing degrees.

We prove that there exists a noncomputable c.e. real which is low for weak 2-randomness, a definition of randomness due to Kurtz, and that all reals which are low for weak 2-randomness are low for Martin-Löf randomness.

We characterize the class of c.e. degrees that bound a critical triple as those degrees that compute a function that has no ω-c.e. approximation.

The number of online courses in business schools is growing dramatically, but little has been published about teaching business ethics courses online. This article addresses key pedagogical design, delivery, student engagement, and assessment issues that should be considered when creating a high-quality, asynchronous online business ethics course for either undergraduate or graduate business student populations. Best practices are discussed within an integrative case study approach based on the experiences of a director of online faculty development and two accomplished online business (...) ethics instructors, one teaching at a small college and the other at a research-oriented university—their successes, learning opportunities, and recommendations.

We examine the sequences A that are low for dimension, i.e. those for which the effective dimension relative to A is the same as the unrelativized effective dimension. Lowness for dimension is a weakening of lowness for randomness, a central notion in effective randomness. By considering analogues of characterizations of lowness for randomness, we show that lowness for dimension can be characterized in several ways. It is equivalent to lowishness for randomness, namely, that every Martin-Löf random sequence has effective dimension (...) 1 relative to A, and lowishness for K, namely, that the limit of KA/K is 1. We show that there is a perfect [Formula: see text]-class of low for dimension sequences. Since there are only countably many low for random sequences, many more sequences are low for dimension. Finally, we prove that every low for dimension is jump-traceable in order nε, for any ε > 0. (shrink)

We investigate notions of randomness in the space ${{\mathcal C}(2^{\mathbb N})}$ of continuous functions on ${2^{\mathbb N}}$ . A probability measure is given and a version of the Martin-Löf test for randomness is defined. Random ${\Delta^0_2}$ continuous functions exist, but no computable function can be random and no random function can map a computable real to a computable real. The image of a random continuous function is always a perfect set and hence uncountable. For any ${y \in 2^{\mathbb N}}$ , (...) there exists a random continuous function F with y in the image of F. Thus the image of a random continuous function need not be a random closed set. The set of zeroes of a random continuous function is always a random closed set. (shrink)

This essay considers the relation between Don Quixote's hunger and the disenchantment (Entzauberung) that Max Weber understood as paradigmatic of the modern condition. Whereas hunger functions within a Hegelian dialectic of desire in Cervantes' novel, literary representations of hunger from later periods (in Kafka and post-Holocaust Polish poetry) acknowledge the cosmic insignificance of human need by substituting the desire for recognition with a desire for self-abdication. While Don Quixote's hunger drives him to seek recognition for his dream world, modern (...) literature's hungry heroes respond to hunger by changing their metaphysical identities. Like desire, hunger functions in the literatures of modernity as an index of psychic wholeness or of its lack, both enabling and resisting the hero's assimilation with the world outside the self.

ABSTRACTThis article investigates Habermas's communicative ethic in relation to changes in the roles of institutions and the state. I reference Alexy, Weber and Taylor, arguing that an artificial delimitation of the public sphere as disparate from the private or religious cramps the capacity of those identified as outsiders to communicate within it. I question the ability of public reason as Habermas has outlined it to meet the challenges it faces regarding interreligious dialogue and integration in democratic societies, and I (...) suggest, instead, an approach more open to dialogue with religions in terms that are more comprehensible to them.

I explore how gender can shape the pragmatics of speech. In some circumstances, when a woman deploys standard discursive conventions in order to produce a speech act with a specific performative force, her utterance can turn out, in virtue of its uptake, to have a quite different force—a less empowering force—than it would have if performed by a man. When members of a disadvantaged group face a systematic inability to produce a specific kind of speech act that they are entitled (...) to perform—and in particular when their attempts result in their actually producing a different kind of speech act that further compromises their social position and agency—then they are victims of what I call discursive injustice. I examine three examples of discursive injustice. I contrast my account with Langton and Hornsby's account of illocutionary silencing. I argue that lack of complete control over the performative force of our speech acts is universal, and not a special marker of social disadvantage. However, women and other relatively disempowered speakers are sometimes subject to a distinctive distortion of the path from speaking to uptake, which undercuts their social agency in ways that track and enhance existing social disadvantages.

Max Weber (1864-1920), generally known as a founder of modern social science, was concerned with political affairs throughout his life. The texts in this edition span his career and include his early inaugural lecture The Nation State and Economic Policy, Suffrage and Democracy in Germany, Parliament and Government in Germany under a New Political Order, Socialism, The Profession and Vocation of Politics, and an excerpt from his essay The Situation of Constitutional Democracy in Russia, as well as other shorter (...) writings. Together they illustrate the development of his thinking on the fate of Germany and the nature of politics in the modern western state in an age of cultural 'disenchantment'. The introduction discusses the central themes of Weber's political thought, and a chronology, notes and an annotated bibliography place him in his political and intellectual context. (shrink)

Logical paradoxes – like the Liar, Russell's, and the Sorites – are notorious. But in Paradoxes and Inconsistent Mathematics, it is argued that they are only the noisiest of many. Contradictions arise in the everyday, from the smallest points to the widest boundaries. In this book, Zach Weber uses “dialetheic paraconsistency” – a formal framework where some contradictions can be true without absurdity – as the basis for developing this idea rigorously, from mathematical foundations up. In doing so, (...) class='Hi'>Weber directly addresses a longstanding open question: how much standard mathematics can paraconsistency capture? The guiding focus is on a more basic question, of why there are paradoxes. Details underscore a simple philosophical claim: that paradoxes are found in the ordinary, and that is what makes them so extraordinary. (shrink)

This chapter explores two kinds of testimonial trust, what we call ‘evidential trust’ and ‘non-evidential trust’ with the aim of asking how testimonial trust could provide epistemic reasons for belief. We argue that neither evidential nor non-evidential trust can play a distinctive role in providing evidential reasons for belief, but we tentatively propose that non-evidential trust can in some circumstances provide a novel kind of epistemic reason for belief, a reason of epistemic facilitation. The chapter begins with an extensive discussion (...) of standard accounts of both kinds of trust and criticises especially the standard accounts of non-evidential trust. A new account of non-evidential trust is offered that avoids a number of difficulties that plague the standard accounts by rejecting what we call ‘attitude-liability assumptions’. (shrink)

The recent literature on causality has seen the introduction of several distinctions within causality, which are thought to be important for understanding the widespread scientific practice of focusing causal explanations on a subset of the factors that are causally relevant for a phenomenon. Concepts used to draw such distinctions include, among others, stability, specificity, proportionality, or actual-difference making. In this contribution, I propose a new distinction that picks out an explanatorily salient class of causes in biological systems. Some select causes (...) in complex biological systems, I argue, have the property of enabling coherent causal control of these systems. Examples of such control variables include hormones and other signaling molecules, e.g., TOR (target of rapamycin), morphogens or the products of homeotic selector genes in embryonic pattern formation. I propose an analysis of this notion based on concepts borrowed from causal graph theory. (shrink)

I examine different arguments that could be used to establish indeterminism of neurological processes. Even though scenarios where single events at the molecular level make the difference in the outcome of such processes are realistic, this falls short of establishing indeterminism, because it is not clear that these molecular events are subject to quantum mechanical uncertainty. Furthermore, attempts to argue for indeterminism autonomously (i.e., independently of quantum mechanics) fail, because both deterministic and indeterministic models can account for the empirically observed (...) behavior of ion channels.

Purpose: We sought to examine the ethical, legal, and social implications (ELSI) literature research and scholarship types, topics, and contributing community fields of training as a first step to charting the broader ELSI community’s future priorities and goals. Methods: We categorized 642 articles and book chapters meeting inclusion criteria for content in both human genetics or genomics and ethics or ELSI during a 5-year period (2003–2008) according to research and scholarship types, topics, and the area of advanced training of the (...) first-listed author. Research and scholarship type categories were developed and characterized through in-depth review of 95 randomly sampled publications from the larger group. Results: There is a single dominant approach to ELSI, which focuses on ethical and other social issues “downstream” of advances in genomics, the contributors to which predominately have advanced training in medicine or science fields other than social science. A comparatively low percentage of publications primarily offer policy recommendations, and these are much more likely to be written by those with advanced training in law than is the case for the literature as a whole. Social science studies predominately employ qualitative methods and vary significantly with respect to the extent and types of recommendations offered. Two further types of ELSI research and scholarship offer alternative models for so-called “normative” work in this field. Conclusion: Considering topics, training, and types of ELSI research and scholarship from the most recent past allows for a baseline perspective that is sorely needed in charting this field’s future course.

Several authors have used the notion of causal specificity in order to defend non-parity about genetic causes (Waters 2007, Woodward 2010, Weber 2017, forthcoming). Non-parity in this context is the idea that DNA and some other biomolecules that are often described as information-bearers by biologists play a unique role in life processes, an idea that has been challenged by Developmental Systems Theory (e.g., Oyama 2000). Indeed, it has proven to be quite difficult to state clearly what the alleged special (...) role of genetic causes consists in. In this paper, I show that the set of biomolecules that are normally considered to be information-bearers (DNA, mRNA) can be shown to be the most specific causes of protein primary structure, provided that causal specificity is measured over a relevant space of biological possibilities, disregarding physical as well as logically possible states of the causal variables.

Human Rights Education (HRE) has traditionally been articulated in terms of cultivating better citizens or world citizens. The main preoccupation in this strand of HRE has been that of bridging a gap between universal notions of a human rights subject and the actual locality and particular narratives in which students are enmeshed. This preoccupation has focused on ‘learning about the other’ in order to improve relations between plural ‘others’ and ‘us’ and reflects educational aims of national identity politics in citizenship (...) education. The article explores the learning of human rights through narratives in relations, drawing on Hannah Arendt and Sharon Todd. For this re-thinking of relations in learning human rights, the article argues that HRE needs to address both competing historical narratives on the drafting of the Universal Declaration on Human Rights (UDHR) as well as unique life narratives of learners.

A commonly neglected feature of the so-called Equal Weight View, according to which we should give our peers’ opinions the same weight we give our own, is its prima facie incompatibility with the common picture of philosophy as an armchair activity: an intellectual effort to seek a priori knowledge. This view seems to imply that our beliefs are more likely to be true if we leave our armchair in order to find out whether there actually are peers who, by disagreeing (...) with us, force us to revise our beliefs. This article argues that the Equal Weight View should be spelled out in such a way that not only actual peer disagreement requires us to revise our beliefs, but also merely possible peer disagreement. This result is not a reductio ad absurdum of the view. Quite the opposite: it shows that the view is, contrary to appearance, compatible with our common way of doing philosophy. (shrink)

Controversial and provocative, To Be Real is a blueprint for the creation of a new political force.

Miranda Fricker claims that a “gap” in collective hermeneutical resources with respect to the social experiences of marginalized groups prevents members of those groups from understanding their own experiences (Fricker 2007). I argue that because Fricker misdescribes dominant hermeneutical resources as collective, she fails to locate the ethically bad epistemic practices that maintain gaps in dominant hermeneutical resources even while alternative interpretations are in fact offered by non-dominant discourses. Fricker's analysis of hermeneutical injustice does not account for the possibility that (...) marginalized groups can be silenced relative to dominant discourses without being prevented from understanding or expressing their own social experiences. I suggest that a gap in dominant hermeneutical resources is ambiguous between two kinds of unknowing: hermeneutical injustice suffered by members of marginalized groups, and epistemically and ethically blameworthy ignorance perpetrated by members of dominant groups.

Evolution was not discovered single-handedly, Rebecca Stott argues, contrary to what has become standard lore, but is an idea that emerged over many centuries, advanced by daring individuals across the globe who had the imagination to speculate on nature's extraordinary ways, and who had the courage to articulate such speculations at a time when to do so was often considered heresy.

It is a truism that humans are social animals. Thus, it is no surprise that we understand the world, each other, and ourselves in terms of social kinds such as money and marriage, war and women, capitalists and cartels, races, recessions, and refugees. Social kinds condition our expectations, inform our preferences, and guide our behavior. Despite the prevalence and importance of social kinds, philosophy has historically devoted relatively little attention to them. With few exceptions, philosophers have given pride of place (...) to the kinds studied by the natural sciences, especially physics. However, philosophical interest in social kinds is growing in recent years. I critically examine answers to a cluster of related questions concerning the metaphysics of social kinds. Are social kinds natural kinds? Do social kinds have essences? Are social kinds mind dependent? Are social kinds real? (shrink)

Over the course of its history, feminist standpoint theory has encountered a number of problems which reveal divisions among its supporters over certain fundamental philosophical commitments. This chapter sketches a phenomenological account of perception that can begin to address these problems, drawn largely from Maurice Merleau-Ponty’s Phenomenology of Perception. Merleau-Ponty can help us resolve these issues by providing an account of perspectival perception wherein a multiplicity of different perceptual standpoints all nonetheless put us in touch with a single external world, (...) and in which some standpoints may be better than others when it comes to accessing certain features of this world. For Merleau-Ponty, the proliferation of standpoints need not lead us into an unacceptably relativistic framework, as long as we are able to conceive of each of these standpoints as giving whoever occupies it access to some particular aspect of a singular, real, shared world.

Phase 1 healthy volunteer clinical trials—which financially compensate subjects in tests of drug toxicity levels and side effects—appear to place pressure on each joint of the moral framework justifying research. In this article, we review concerns about phase 1 trials as they have been framed in the bioethics literature, including undue inducement and coercion, unjust exploitation, and worries about compromised data validity. We then revisit these concerns in light of the lived experiences of serial participants who are income-dependent on phase (...) 1 trials. We show how participant experiences shift attention from discrete exchanges, behaviors, and events in the research enterprise to the ongoing and dynamic patterns of serial participation in which individual decision-making is embedded in collective social and economic conditions and shaped by institutional policies. We argue in particular for the ethical significance of structurally diminished voluntariness, routine powerlessness in setting the terms of exchange, and incentive structures that may promote pharmaceutical interests but encourage phase 1 healthy volunteers to skirt important rules.

Darwin famously held that his use of the term "chance" in evolutionary theory merely "serves to acknowledge plainly our ignorance of the causes of each particular variation". Is this a tenable view today? Or should we revise our thinking about chance in evolution in light of the more advanced, quantitative models of Neo-Darwinian theory, which make substantial use of statistical reasoning and the concept of probability? Is determinism still a viable metaphysical doctrine about biological reality after the quantum revolution in (...) physics, or dowe have to abandon it in favor of an objective indeterminism? In light of such reflections, what is the relevant interpretation of probability in evolutionary theory? Do biologists use the concept of probability because they are finite cognitive agents or because the evolutionary process is fundamentally probabilistic? In this paper, I will show that we do not yet fully understand the nature of chance in evolution. (shrink)

Prominent mathematician William Thurston was praised by other mathematicians for his intellectual generosity. But what does it mean to say Thurston was intellectually generous? And is being intellectually generous beneficial? To answer these questions I turn to virtue epistemology and, in particular, Roberts and Wood's (2007) analysis of intellectual generosity. By appealing to Thurston's own writings and interviewing mathematicians who knew and worked with him, I argue that Roberts and Wood's analysis nicely captures the sense in which he was intellectually (...) generous. I then argue that intellectual generosity is beneficial because it counteracts negative effects of the reward structure of mathematics that can stymie mathematical progress. (shrink)

The COVID-19 pandemic has led a number of countries to introduce restrictive ‘lockdown’ policies on their citizens in order to control infection spread. Immunity passports have been proposed as a way of easing the harms of such policies, and could be used in conjunction with other strategies for infection control. These passports would permit those who test positive for COVID-19 antibodies to return to some of their normal behaviours, such as travelling more freely and returning to work. The introduction of (...) immunity passports raises a number of practical and ethical challenges. In this paper, we seek to review the challenges relating to various practical considerations, fairness issues, the risk to social cooperation and the impact on people’s civil liberties. We make tentative recommendations for the ethical introduction of immunity passports. (shrink)

We routinely need to process the identity of many faces around us, and how the brain achieves this is still the subject of much research in cognitive neuroscience. To date, insights on face identity processing have come from both healthy and clinical populations. However, in order to directly compare results across and within participant groups, and across different studies, it is crucial that a standard task is utilised which includes different exemplars (for example, non-face stimuli along with faces), is memory-neutral, (...) and taps into identity recognition across orientation and across viewpoint change. The goal of this study was to test a previously behaviourally tested, optimised face and object identity matching design in a healthy control sample whilst being scanned using fMRI. Specifically, we investigated categorical, orientation, and category-specific orientation effects while participants were focused on identity processing of simultaneously presented exemplar stimuli. Alongside observing category and orientation specific effects in a distributed set of brain regions, we also saw an interaction between stimulus category and orientation in the bilateral fusiform gyrus and bilateral middle occipital gyrus. Generally these clusters showed the pattern of a heightened response to inverted, as opposed to upright faces; and to upright, as opposed to inverted shoes. These results are discussed in relation to previous studies and to potential future research within prosopagnosic individuals. (shrink)
