In the Tractatus Wittgenstein wrote: “Skepticism is not irrefutable, but obviously nonsensical when it tries to raise doubts where no questions can be asked.” In this paper I show how Wittgenstein developed this insight in On Certainty. My principal aim is to show that this is a logical insight, that it is bound up with the distinction between saying and showing, and that one misses the point of On Certainty if one reads it, as some commentators have, in epistemological terms. (...) Throughout all of this I pay special attention to why Wittgenstein thought that skepticism is nonsensical, and what it might mean to say that philosophy is a logical investigation. (shrink)

This work provides a thorough index of terms found in Ludwig Wittgenstein's On Certainty. The index includes not only every philosophical term found in Wittgenstein's text, but also many non-philosophical terms when they are used in highly charged philosophical contexts. In all, there are some 575 main entries. Moreover, a concerted effort is made to indicate in what connections a given term is used by adding subordinate qualifying phrases to the main entries. For crucial terms (e.g., 'know,' 'proposition,' 'doubt,' etc.) (...) the sub-entries indicating context are quite extensive. (shrink)

ObjectiveTo determine the effects of learning interventions aimed at optimizing the quality of physical education on psychomotor, cognitive, affective and social learning outcomes in children and adolescents.DesignA systematic review and meta-analysis.Data SourcesAfter searching PsycInfo, ERIC, and SportDiscus electronic databases, we identified 135 eligible studies published between January 1, 1995 to May 1, 2021.Eligibility Criteria for Selecting StudiesWe included randomized controlled trials, quasi-experimental studies, and controlled trials that assessed the effect of a PE-based intervention against one of the four identified learning (...) domains in youth at school.ResultsOne hundred and thirty five studies with over 42,500 participants and 193 calculated effect sizes were included in the study. The mean effect across all the learning and development outcomes was small to medium. When adjusted for publication bias using the Duval and Tweedie Trim and Fill Method, this mean effect size increased to d = 0.40. Effect sizes varied significantly based on learning and development outcomes. Interventions that consistently report above or below the mean d = 0.40 effect are identified based on learning outcome. The greatest effects across interventions were witnessed in psychomotor learning outcomes followed by affective, social, and cognitive learning outcomes. A minority of PE interventions captured by this systematic review and meta-analysis reported having a negative effect on student learning and development.ConclusionThe interventions with the greatest effects on student learning and development were dependant on the learning domains. Some PE interventions with a pedagogical focus such as games-based approaches, TARGET/Mastery Teaching, and Sport Education were found to be strong investments across multiple domains. The evidence is limited however by consistency in intervention dosage, study design, and data collection instruments. The study received no internal or external funding and was not prospectively registered. (shrink)

Formal arguments have proven that avoiding the Repugnant Conclusion is impossible without rejecting one or more highly plausible population principles. To many, such proofs establish not only a deep challenge for axiology, but also pose an important practical problem of how policymaking can confidently proceed without resolving any of the central questions of population ethics. Here we offer deflationary responses: first to the practical challenge, and then to the more fundamental challenge for axiology. Regarding the practical challenge, we provide an (...) overview of recent literature that explores the implications for public policy of the Repugnant Conclusion and related puzzles within population ethics, and shows that there is more commonality in the implications of different population axiologies than is generally recognized. The upshot is that uncertainty about population ethics presents no important problem for policymaking, and the importance of population ethics to policymaking has been overstated. We then turn to more fundamental issues about axiology, and describe a new series of formal proofs that undermine the idea that any plausible axiology could avoid the Repugnant Conclusion, including those that are assumed to avoid it in the literature. The philosophical upshot is that the Repugnant Conclusion cannot plausibly be avoided, and so it is a mistake to assume as a constraint on a plausible axiology that it must be avoided, as is assumed by most of the literature in population ethics, including by all of the fundamental impossibility theorems.

This article outlines a training activity that can enable both business and governmental professionals to translate the principles in a code of ethics to a specific list of company-related behaviors ranging from highly ethical to highly unethical. It also explores how this list can become a concrete model to follow in making ethical decisions. The article begins with a discussion as to what will improve ethical decision making in business and government. This leads us to explore the factors that can (...) most easily lead to improvement, namely a comprehensive code of conduct and employee training. From there we look at the Critical Incident Technique as a training strategy that has the potential for identifying those behaviors that distinguish really outstanding behaviors from those that go by the book, and can be used to encourage more independent thinking and to set expectations for future decisions. If employees are given the skills and examples that will enable them to make better decisions, they can apply them to any situation. (shrink)

Proof-theoretic reflection principles are schemas which attempt to express the soundness of arithmetical theories within their own language, e.g., ${\mathtt{{Prov}_{\mathsf {PA}} \rightarrow \varphi }}$ can be understood to assert that any statement provable in Peano arithmetic is true. It has been repeatedly suggested that justification for such principles follows directly from acceptance of an arithmetical theory $\mathsf {T}$ or indirectly in virtue of their derivability in certain truth-theoretic extensions thereof. This paper challenges this consensus by exploring relationships between reflection principles (...) and principles of mathematical and transfinite induction as well as the status of the latter with respect to various foundational characterizations of number theory.

Joshua Greene has argued that several lines of empirical research, including his own fMRI studies of brain activity during moral decision-making, comprise strong evidence against the legitimacy of deontology as a moral theory. This is because, Greene maintains, the empirical studies establish that “characteristically deontological” moral thinking is driven by prepotent emotional reactions which are not a sound basis for morality in the contemporary world, while “characteristically consequentialist” thinking is a more reliable moral guide because it is characterized by greater (...) cognitive command and control. In this essay, I argue that Greene does not succeed in drawing a strong statistical or causal connection between prepotent emotional reactions and deontological theory, and so does not undermine the legitimacy of deontological moral theories. The results that Greene relies on from neuroscience and social psychology do not establish his conclusion that consequentialism is superior to deontology. (shrink)

This paper explores the relationship borne by the traditional paradoxes of set theory and semantics to formal incompleteness phenomena. A central tool is the application of the Arithmetized Completeness Theorem to systems of second-order arithmetic and set theory in which various “paradoxical notions” for first-order languages can be formalized. I will first discuss the setting in which this result was originally presented by Hilbert & Bernays (1939) and also how it was later adapted by Kreisel (1950) and Wang (1955) in (...) order to obtain formal undecidability results. A generalization of this method will then be presented whereby Russell’s paradox, a variant of Mirimanoff’s paradox, the Liar, and the Grelling–Nelson paradox may be uniformly transformed into incompleteness theorems. Some additional observations are then framed relating these results to the unification of the set theoretic and semantic paradoxes, the intensionality of arithmetization (in the sense of Feferman, 1960), and axiomatic theories of truth.

Computationalism holds that our grasp of notions like ‘computable function’ can be used to account for our putative ability to refer to the standard model of arithmetic. Tennenbaum's Theorem has been repeatedly invoked in service of this claim. I will argue that not only do the relevant class of arguments fail, but that the result itself is most naturally understood as having the opposite of a reference-fixing effect — i.e., rather than securing the determinacy of number-theoretic reference, Tennenbaum's Theorem points (...) towards a sense in which portions of our computational vocabulary should be regarded as model-relative.

This paper presents a systematic study of the prehistory of the traditional subsystems of second-order arithmetic that feature prominently in the reverse mathematics program of Friedman and Simpson. We look in particular at: (i) the long arc from Poincar\'e to Feferman as concerns arithmetic definability and provability, (ii) the interplay between finitism and the formalization of analysis in the lecture notes and publications of Hilbert and Bernays, (iii) the uncertainty as to the constructive status of principles equivalent to Weak K\"onig's (...) Lemma, and (iv) the large-scale intellectual backdrop to arithmetical transfinite recursion in descriptive set theory and its effectivization by Borel, Lusin, Addison, and others. (shrink)

One formulation of the Categorical Imperative tells us to treat humanity as an end in itself. It has become common to think that ‘humanity’ (die Menschheit) here refers to some minimal power of rationality that is necessarily possessed by any rational agent, but I argue that this common reading is misguided. Instead, ‘humanity’ refers to a good will, the will of a being who is committed to moral principles. This good will reading of ‘humanity’ is not only suggested by passages (...) in which Kant specifically discusses humanity, but also is more consistent with the main ideas of Kant's ethics. (shrink)

This article details day-to-day ethics issues facing MBAs who occupy entry-level and mid-level management positions and offers defined examples of the stressors these managers face. The study includes lower-level managers, essentially excluded from extant literature, and focuses on workplace behaviors both undertaken and observed. Results indicate that pressures from internal organization sources, and ambiguity in letter versus spirit of rules, account for over a third of the most frequent unethical situations encountered, and that most managers did not expect to face (...) those issues. Various contextual factors accounted for 32% of the organizational factors that affected decisions. We discuss implications for the workplace, especially the unique ethics challenges for newer managers. (shrink)

In an effort to address healthcare disparities in lesbian, gay, bisexual, transgender, and queer populations, many hospitals and clinics institute diversity training meant to increase providers’ awareness of and sensitivity to this patient population. Despite these efforts, many healthcare spaces remain inhospitable to LGBTQ patients and their loved ones. Even in the absence of overt forms of discrimination, LGBTQ patients report feeling anxious, unwelcome, ashamed, and distrustful in healthcare encounters. We argue that these negative experiences are produced by a variety (...) of subtle, ostensibly insignificant features of healthcare spaces and interpersonal interactions called microaggressions. Healthcare spaces and providers often convey heteronormative microaggressions, which communicate to LGBTQ—and, we suggest, intersex and asexual —people that their identities, experiences, and relationships are abnormal, pathological, unexpected, unwelcome, or shameful. We identify heteronormative microaggressions common to healthcare settings and specify how they negatively impact LGBTQIA patients. We argue that standard diversity training cannot sufficiently address heteronormative microaggressions. Despite these challenges, healthcare institutions and providers must take responsibility for heteronormative microaggressions and take steps to reduce their frequency and mitigate their effects on LGBTQIA care. We conclude by offering strategies for problem-solving at the level of medical education, institutional culture and policy, and individual awareness. (shrink)

This article approaches social media from the theory of the religio-political practice of acclamation revived by Agamben and following twentieth-century social and political thought and theology (of Weber, Peterson, Schmitt, Kantorowicz). It supplements that theory by more recent political-theoretical, historical and sociological investigations and regards acclamation as a ‘social institution’ following Mauss. Acclamation is a practice that forms publics, whether as the direct presence of the ‘people’, mass-mediated ‘public opinion’, or a ‘public mood’ decipherable through countless social media postings. The (...) article surveys issues of differential geographies of access, weighting of posts, value-creation, orality and gesture, algorithmic governmentality, and Big Data and knowledge production. It argues that social media constitute a public from a mass of individualized, private postings. It concludes that they make possible forms of political calculability and action, yet are continuous with ritual and liturgical elements of political life. This study contributes to an analytics of publicity. (shrink)

This paper contends that eating shapes the self; that is, our practices and understandings of eating can cultivate, reinforce, or diminish important aspects of the self, including agency, values, capacities, affects, and self-understandings. I argue that these self-shaping effects should be included in our ethical analyses and evaluations of eating. I make a case for this claim through an analysis and critique of the hypothesis that young women’s vegetarianism is a risk, sign, or “cover” for eating disorders or disordered eating. (...) After outlining the relevant empirical literature, I suggest that the evidence for this hypothesis is inconclusive. Given this uncertainty, we should consider the risks of making a mistake when accepting or rejecting this understanding of young women’s eating. I argue that these risks importantly include negative effects on the self, such as damage to moral and epistemic agency. Along with other potential consequences of mistakenly accepting the hypothesis, these effects give us reason to reject it pending more conclusive research. Overall, this paper offers a philosophical intervention into the debate over the relationship between vegetarianism and eating disorders while illustrating the ethical importance and relevance of eating as a self-shaping activity.

Countering claims of its impossibility, this paper argues for economic theology as an intelligible figure of contemporary political rationality and organization, and a distinctive analytical strategy in relation to forms of liberal and neoliberal governmentality and the contemporary management of social life. As an analytical strategy, it has two arms: an institutional one, drawing upon Michel Foucault’s work on the pastorate; and a conceptual one, following from Giorgio Agamben on oikonomia, order and providence. Economic theology was the arcana of 20th-century (...) debates on both political theology and governmentality and a condition for their emergence. It formed the horizon of Carl Schmitt’s intervention of a political theology in response to Max Weber, and, as the pastorate, it was for Foucault the historical background of the emergence of the liberal arts of government. While appearing as a new paradigm, it thus has a measure of priority over our more established ones. Furthermore, to the extent that economic theology comes to occupy the place of political rationality in contemporary liberal-democratic societies, the political becomes less a rational public sphere and more a form of public liturgy.

This paper argues that common social narratives about unhealthy eaters can cause significant damage to agency. I identify and analyze a narrative that combines a “control model” of eating agency with the healthist assumption that health is the ultimate end of eating. I argue that this narrative produces and enables four types of damage to the agency of those identified as unhealthy eaters. Due to uncertainty about what counts as healthy eating and various forms of prejudice, the unhealthy eater label (...) and its harms to agency are more likely to stick to some people than others and may reinforce patterns of oppression. I argue that fat people are especially vulnerable to this identification and the damage it can do. I then consider possible “counterstories” about unhealthy eaters, alternative narratives that might be less damaging to agency than the control narrative. I identify one promising counterstory but suggest that it may be limited when it comes to repairing damage to the agency of fat people. Overall, this paper illustrates some of the complex ways that healthism about eating affects agency, and emphasizes the ethical importance of the ways we think about and discuss eating and eaters.

The goal of this paper is to explore the significance of Montague’s paradox—that is, any arithmetical theory $T\supseteq Q$ over a language containing a predicate $P$ satisfying $P\rightarrow \varphi $ and $T\vdash \varphi \,\therefore\,T\vdash P$ is inconsistent—as a limitative result pertaining to the notions of formal, informal, and constructive provability, in their respective historical contexts. To this end, the paradox is reconstructed in a quantified extension $\mathcal {QLP}$ of Artemov’s logic of proofs. $\mathcal {QLP}$ contains both explicit modalities $t:\varphi $ (...) and also proof quantifiers $x:\varphi $. In this system, the basis for the rule NEC is decomposed into a number of distinct principles governing how various modes of reasoning about proofs and provability can be internalized within the system itself. A conceptually motivated resolution to the paradox is proposed in the form of an argument for rejecting the unrestricted rule NEC on the basis of its subsumption of an intuitively invalid principle pertaining to the interaction of proof quantifiers and the proof-theorem relation expressed by explicit modalities.

It was proposed that ethical evaluation of insurance claim padding behavior would be affected by characteristics of the policyholder, insurance agent, and company. These three factors were manipulated in written scenarios and the premise was tested in a factorial experimental design. No significant support was found for an effect of any of the three factors on ethical perceptions of claim padding. However, females found claims padding to be significantly less ethical than males. Given a claim scenario where the actual loss (...) was $500 and the claimed amount was $3000, subjects awarded an average of $986.91 on the claim. Many respondents were willing to compensate victims for intangible losses as well as tangible losses. (shrink)

Human culture is uniquely complex compared to other species. This complexity stems from the accumulation of culture over time through high- and low-fidelity transmission and innovation. One possible reason for why humans retain and create culture, is our ability to modulate teaching strategies in order to foster learning and innovation. We argue that teaching is more diverse, flexible, and complex in humans than in other species. This particular characteristic of human teaching rather than teaching itself is one of the reasons (...) for human’s incredible capacity for cumulative culture. That is, humans unlike other species can signal to learners whether the information they are teaching can or cannot be modified. As a result teaching in humans can be used to support high or low fidelity transmission, innovation, and ultimately, cumulative culture. (shrink)

The claim that everyone ought to be treated with respect is a familiar and widely accepted prescription in recent moral philosophy, often expressed as a principle of ‘respect for persons.’ I argue that this principle need not be justified by a claim that every person possesses some feature – dignity, autonomy, value, or the like – that makes her worthy of respect. There is abundant conceptual space within many approaches to moral philosophy, including a Kantian approach, to affirm a duty (...) of respect for all persons, while denying that the duty is justified by the respect-worthiness of every person.

Richard Rorty does have something ‘to say to [Black Americans]’ and to their racially conscious nonblack allies in the sense that his understanding of liberalism, his prophecies about the future and his urgent appeals to the American Left all paint a picture of a white middle class fully prepared to make life increasingly miserable for Black Americans unless it is ‘protected from catastrophe’. Rorty hopes that this group will undergo a moral transformation that enables it to see past its narrow (...) group interests, but doubts that it will. He, nevertheless, prescribes a politics of hope and appeasement as a hedge against both despair and backsliding. In so doing, he fails to appreciate the availability and the suitability of an alternative ‘racial realist’ (and tragicomic) posture vis-à-vis American liberalism inspired by thinkers like Ralph Ellison, James Baldwin and Derrick Bell. This alternative enables racially conscious Americans to respond to the intransigence of (certain) white Americans with cunning rather than by escaping into fantasies of a ‘dream country’ unmarked by the damage caused by racism and its long-lingering effects. I uncover and explore this alternative through Rorty’s warnings regarding the white middle class, a somewhat surprising consistency between Rorty’s brand of class politics and Bell’s understanding of ‘racial fortuity’, and, finally, through a development of Bell’s ‘racial realist’ posture combined with Baldwin’s ‘uses of the blues’ resulting in a ‘hard-eyed’ tragicomic sensibility sufficient to effectively pair continued struggle with creative consolation and resilience.

This paper engages the question ‘Does the consistency of a set of axioms entail the existence of a model in which they are satisfied?’ within the frame of the Frege-Hilbert controversy. The question is related historically to the formulation, proof and reception of Gödel’s Completeness Theorem. Tools from mathematical logic are then used to argue that there are precise senses in which Frege was correct to maintain that demonstrating consistency is as difficult as it can be, but also in which (...) Hilbert was correct to maintain that demonstrating existence given consistency is as easy as it can be. (shrink)

There seems to be something wrong with passing moralistic judgments on others’ moral character. Immanuel Kant’s ethics provides insight into an underexplored way in which moralistic judgments are problematic, namely, that they are both a sign of fundamentally poor character in the moralistic person herself and an obstacle to that person’s own moral self-improvement. Kant’s positions on these issues provide a basically compelling argument against moralistic judgment of others, an argument that can be detached from the most controversial elements of (...) Kantian ethics to stand as plausible and instructive in its own right. (shrink)

In the UK, many have argued that the past five years or so have seen an increase in the radicalism and visibility of feminist activism, jarring somewhat with the strong emphasis on loss in much recent scholarship – as well as media commentary – on feminist politics. Against this backdrop, this article asks how, and to what extent, this resurgence of feminist activism has unsettled the centrality of loss within the affective economies of contemporary British feminism, by examining a range (...) of recent texts produced within academic, activist, publishing and media spheres. After arguing that attachments to loss remain remarkably intransigent, the latter part of the article draws on Sara Ahmed’s account of ‘sticky affects’ to provide a theoretical account of why notions such as ‘young women are not feminist’ and ‘feminist activism is a thing of the past’ continue to yield such force despite empirical evidence to the contrary.

The Paradox of the Knower was originally presented by Kaplan and Montague [26] as a puzzle about the everyday notion of knowledge in the face of self-reference. The paradox shows that any theory extending Robinson arithmetic with a predicate K satisfying the factivity axiom K → A as well as a few other epistemically plausible principles is inconsistent. After surveying the background of the paradox, we will focus on a recent debate about the role of epistemic closure principles in the (...) Knower. We will suggest this debate sheds new light on the concept of knowledge which is at issue in the paradox – i.e. is it a “thin” notion divorced from concepts such as evidence or justification, or is it a “thick” notion more closely resembling mathematical provability? We will argue that a number of features of the paradox suggest that the latter option is more plausible. Along the way, we will provide a reconstruction of the paradox using a quantified extension of Artemovʼs [2] Logic of Proofs, as well as a series of results linking the original formulation of the paradox to reflection principles for formal arithmetic. On this basis, we will argue that while the Knower can be understood to motivate a distinction between levels of knowledge, it does not provide a rationale for recognizing a uniform hierarchy of knowledge predicates in the manner suggested by Anderson.

This paper offers a defense of the practice of mindless eating. Popular accounts of the practice suggest that it is non-autonomous and to blame for many of society’s food related problems, including the so-called obesity epidemic and the prevalence of diet related illnesses like diabetes. I use Maureen Sie’s “traffic participation” account of agency to argue that some mindless eating is autonomous, or more specifically, agential. Insofar as we value autonomous eating, then, it should be valued. I also argue that (...) mindless eating can be substantively good: it can help us achieve valuable ends, like creating and maintaining community. Acknowledging the agency and value in mindless eating has both practical and ethical benefits. I contend that it can help us preserve the value in mindless eating while suggesting more effective ways to change it, and, by offering a new narrative about mindless eaters, may be less damaging to agency than popular narratives.

Computational complexity theory is a subfield of computer science originating in computability theory and the study of algorithms for solving practical mathematical problems. Amongst its aims is classifying problems by their degree of difficulty — i.e., how hard they are to solve computationally.
