Subjectivists about practical normativity hold that an agent’s favoring and disfavoring attitudes give rise to practical reasons. On this view, an agent’s normative reason to choose vanilla over chocolate ice cream ultimately turns on facts about what appeals to her rather than facts about what her options are like attitude-independently. Objectivists—who ground reasons in the attitude-independent features of the things we aim at—owe us an explanation of why it is rational to choose what we favor, if not because favoring is (...) a source of reasons. My aim in this paper is to supply such a story. The proposal is roughly that when an agent cannot base her choices on her judgments about what she has most reason to do, structural rationality extends to her a license to choose something just because she favors it, without imbuing favoring with the authority of a normative reason.

The stream of human consciousness appears to be interruptible, in that we can experience a sensation of ‘returning to ourselves after an absence of content’ (e.g. sleep, anaesthesia, full-absorption meditation). Prima facie, such evidence poses a challenge to simple applications of theories of consciousness based on electromagnetic or neural activity in the brain, because some of this activity persists during periods of interruption. This paper elaborates one of several possible responses to the challenge. We build on a previous theory in (...) which EM field topology delineates complex macrophenomenal experience. We first apply an analytic lens to identify different ways in which field topologies might generate sensations of ‘absence of content’. We then test the feasibility of a particular phenomenological approach for assessing those field topologies, powered by the unusual lucidity about cessation pathways induced via certain meditation practices and psychedelic dosages. We build computational simulations of these cessation pathways and test them on eight interviewees with various levels of experience in cessation states. We conclude that this approach can generate usable insight, but requires further formalisation to fulfil its potential. The findings tentatively support our claims but the theory remains speculative at this stage. We set out empirical tests with 11 specific predictions, both for further phenomenological research and for brain manipulation research. Although they align neatly, our ontological and cessation theories can also be separated. The paper describes how our theories can be consistent with other perspectives on consciousness, such as variants of predictive processing or global network theory. (shrink)

Concentration of the world’s wealth in the hands of a few, corporate owners as heads of state – these are facts that lend plausibility to Marx' pronouncements. Yet, how should we evaluate his ideas from today’s vantage point?

Naturwissenschaften, Mathematik und Logik waren für Nelson von zentraler Bedeutung. Er pflegte bereits als Jugendlicher intensive Kontakte zu Naturwissenschaftlern und Mathematikern. Dadurch erhielt er Anregungen, die von Anfang an seine philosophischen Ansätze beeinflussten. Inspiriert von der Kant-Fries’schen Philosophie und der Axiomatik der Mathematik, konzipierte Nelson seine Philosophie als exakte Wissenschaft. Wie Kant und Fries betrachtete Nelson die Suche nach den allgemeinen Prinzipien der Naturwissenschaften als Hauptaufgabe der Naturphilosophie. Ergebnis dieser kritischen Analyse ist ein System von metaphysischen Grundsätzen der Naturwissenschaft. Nelson (...) übernimmt Kants Lehre von den Grundsätzen des reinen Verstandes. Keine empirisch gefundene Gesetzmäßigkeit könne diesen Grundsätzen widersprechen. Für die Gesetze der Newton’schen Mechanik hätten, so meint Nelson, Kant und Fries diesen Nachweis erbracht. Deshalb formulierte Nelson das sogenannte Postulat der Mechanistik, gemäß dem alle Naturerscheinungen auf mechanische Vorgänge zurückgeführt werden können. Das starre Festhalten an diesem Postulat veranlasste ihn zur Ablehnung bedeutsamer physikalischer Konzeptionen (z. B. des auf der Elektrodynamik basierenden Relativitätsprinzips, des Nahwirkungskonzepts und des Atommodells). Das „Relativitätsprinzip der Elektrodynamik“ lehnte er mit dem Argument ab, es verhindere die Anwendung der dritten Analogie der Erfahrung, da es den Verzicht auf den Begriff der Gleichzeitigkeit von Naturerscheinungen erzwinge. Eine kritische Nelson-Rezeption muss der Historizität etlicher Thesen Nelsons Rechnung tragen, aber zugleich die Bedeutsamkeit von Kernaussagen Nelson’scher Naturphilosophie im Hinblick auf die modernen Naturwissenschaften untersuchen. Das ist auch die Zielrichtung des vorliegenden Beitrages. Der erste Teil beleuchtet Nelsons wissenschaftliches Umfeld. Einerseits wird untersucht, welche Wissenschaftler Nelson beeinflussten, andererseits soll dargestellt werden, welcher Personenkreis an der Fortentwicklung der Nelson’schen Naturphilosophie beteiligt war. Beispielhaft sollen daran anschließend zwei Themenbereiche aus seinem reichhaltigen Werk disktiert werden, denen besonders im Hinblick auf aktuelle philosophische Diskussionsschwerpunkte Bedeutsamkeit zukommt. Im zweiten Teil werden nämlich Nelsons Betrachtungen zum Verhältnis von Freiheit und Naturnotwendigkeit sowie seine Unterscheidung zwischen wissenschaftlicher und ästhetischer Naturbetrachtung besprochen. Der Beitrag beansprucht nicht, die Rezeptionssgeschichte und den Inhalt von Nelsons Naturphilosophie sowie die aktuelle Bedeutsamkeit seiner Thesen im Detail darzustellen aufzuarbeiten. Vielmehr geht es darum, Ansätze für eine zeitgemäße Interpretation Rezeption aufzuzeigen und anhand von Beispielen zu erörtern. (shrink)

The doctrine of permanent sovereignty over natural resources is a hugely consequential one in the contemporary world, appearing to grant nation-states both jurisdiction-type rights and rights of ownership over the resources to be found in their territories. But the normative justification for that doctrine is far from clear. This article elucidates the best arguments that might be made for permanent sovereignty, including claims from national improvement of or attachment to resources, as well as functionalist claims linking resource rights to key (...) state functions. But it also shows that these defences are insufficient to justify permanent sovereignty and that in many cases they actually count against it as a practice. They turn out to be compatible, furthermore, with the dispersal of resource rights away from the nation-state which global justice appears to demand. (shrink)

In his wide-ranging study of architecture and cultural evolution, Chris Abel argues that, despite progress in sustainable development and design, resistance to changing personal and social identities shaped by a technology-based and energy-hungry culture is impeding efforts to avert drastic climate change. The book traces the roots of that culture to the coevolution of Homo sapiens and technology, from the first use of tools as artificial extensions of the human body to the motorized cities spreading around the world, whose (...) uncontrolled effects are fast changing the planet itself. Advancing a new concept of the meme, called the 'technical meme', as the primary agent of cognitive extension and technical embodiment, Abel proposes a theory of the 'extended self' as a complex and diffuse outcome of that coevolution. Challenging conventional ideas of the self as a separate and autonomous being, the extended self, he explains, encompasses material and spatial as well as psychological and social elements, including the built environment and artifacts, and now reaches out into the virtual world of cyberspace. Drawing upon research into extended cognition and embodied minds from philosophy, psychology and the neurosciences, the book presents a new approach to environmental and cultural studies. N.B. This book was the winner of the International Committee of Architectural Critics 2017 Bruno Zevi Book Award by unanimous decision of the international jury. (shrink)

According to the scientific ideal of modernity, the propositions of science are considered fundamentally fallible. On the other hand, science strives for objective knowledge. Kant saw in the apriori the precondition for objective knowledge. But with the new conception of science the apriori (if it is not to be only logic) has become problematic. With it, however, the objectivity of scientific knowledge is at stake. As long as one grants objectivity to scientific knowledge, the question of the apriori remains topical. (...) On the one hand, this volume wants to trace the historical roots as well as the different interpretations of the apriori, and on the other hand, it wants to ask for approaches for a contemporary reinterpretation of this basic concept.

One of the main challenges confronting Humean accounts of natural law is that Humean laws appear to be unable to play the explanatory role of laws in scientific practice. The worry is roughly that if the laws are just regularities in the particular matters of fact (as the Humean would have it), then they cannot also explain the particular matters of fact, on pain of circularity. Loewer (2012) has defended Humeanism, arguing that this worry only arises if we fail to (...) distinguish between scientific and metaphysical explanations. However, Lange (2013, 2018) has argued that scientific and metaphysical explanations are linked by a transitivity principle, which would undercut Loewer's defense and re-ignite the circularity worry for the Humean. I argue here that the Humean has antecedent reasons to doubt that there are any systematic connections between scientific and metaphysical explanations. The reason is that the Humean should think that scientific and metaphysical explanation have disparate aims, and therefore that neither form of explanation is beholden to the other in its pronouncements about what explains what. Consequently, the Humean has every reason to doubt that Lange's transitivity principle obtains. (shrink)

ABSTRACT This paper argues for a version of sceptical invariantism about knowledge on which the acceptability of knowledge-attributing sentences varies with the context of assessment.

Reproductive genetic technologies allow parents to decide whether their future children will have or lack certain genetic predispositions. A popular model that has been proposed for regulating access to RGTs is the ‘genetic supermarket’. In the genetic supermarket, parents are free to make decisions about which genes to select for their children with little state interference. One possible consequence of the genetic supermarket is that collective action problems will arise: if rational individuals use the genetic supermarket in isolation from one (...) another, this may have a negative effect on society as a whole, including future generations. In this article we argue that RGTs targeting height, innate immunity, and certain cognitive traits could lead to collective action problems. We then discuss whether this risk could in principle justify state intervention in the genetic supermarket. We argue that there is a plausible prima facie case for the view that such state intervention would be justified and respond to a number of arguments that might be adduced against that view.

It may seem that epistemic and practical rationality weigh reasons differently, because ties in practical rationality tend to generate permissions and ties in epistemic rationality tend to generate a requirement to withhold judgment. I argue that epistemic and practical rationality weigh reasons in the same way, but they have different "default biases". Practical rationality is biased toward every option being permissible whereas epistemic rationality is biased toward withholding judgment's being required.

In this paper, we present a survey of the development of the technique of argument diagramming covering not only the fields in which it originated - informal logic, argumentation theory, evidence law and legal reasoning – but also more recent work in applying and developing it in computer science and artificial intelligence. Beginning with a simple example of an everyday argument, we present an analysis of it visualised as an argument diagram constructed using a software tool. In the context of (...) a brief history of the development of diagramming, it is then shown how argument diagrams have been used to analyze and work with argumentation in law, philosophy and artificial intelligence.

Economic pressures, mounting environmental, security and health requirements, are all critical factors that shape economic action. With regard to environmental protection, an economic entity acting as homo oeconomicus finds himself in a situation resembling a prisoner’s dilemma. Signposts for a possible resolution of this dilemma include an environmental management system, a system of environmental law based on the principles of environmental ethics, and a new conception of human nature.

The chapter introduces and characterizes the notion of fittingness. It charts the history of the relation and its relevance to contemporary debates in normative and metanormative philosophy and proceeds to survey issues to do with fittingness covered in the volume’s chapters, including the nature and epistemology of fittingness, the relations between fittingness and reasons, the normativity of fittingness, fittingness and value theory, and the role of fittingness in theorizing about responsibility. The chapter concludes with a brief discussion of issues to (...) do with fittingness that aren’t covered extensively by the volume’s chapters in order to indicate avenues for further research.

Users of psychedelic drugs often report that their sense of being a self or ‘I’ distinct from the rest of the world has diminished or altogether dissolved. Neuroscientific study of such ‘ego dissolution’ experiences offers a window onto the nature of self-awareness. We argue that ego dissolution is best explained by an account that explains self-awareness as resulting from the integrated functioning of hierarchical predictive models which posit the existence of a stable and unchanging entity to which representations are bound. (...) Combining recent work on the ‘integrative self' and the phenomenon of self-binding with predictive processing principles yields an explanation of ego dissolution according to which self-representation is a useful Cartesian fiction: an ultimately false representation of a simple and enduring substance to which attributes are bound which serves to integrate and unify cognitive processing across levels and domains. The self-model is not a mere narrative posit, as some have suggested; it has a more robust and ubiquitous cognitive function than that. But this does not mean, as others have claimed, that the self-model has the right attributes to qualify as a self. It performs some of the right kinds of functions, but it is not the right kind of entity. Ego dissolution experiences reveal that the self-model plays an important binding function in cognitive processing, but the self does not exist. (shrink)

This chapter addresses philosophical questions raised in contemporary work on cosmology. It provides an overview of the Standard Model for cosmology and argues that its deficiency in addressing theories regarding the very early universe can be resolved by introducing a dynamical phase of evolution that eliminates the need for a special initial state. The chapter also discusses recent hypotheses about dark matter and energy, issues that it relates to philosophical debates about underdetermination.

Recent clinical trials show that psychedelics such as LSD and psilocybin can be given safely in controlled conditions, and can cause lasting psychological benefits with one or two administrations. Supervised psychedelic sessions can reduce symptoms of anxiety, depression, and addiction, and improve well-being in healthy volunteers, for months or even years. But these benefits seem to be mediated by "mystical" experiences of cosmic consciousness, which prompts a philosophical concern: do psychedelics cause psychological benefits by inducing false or implausible beliefs about (...) the metaphysical nature of reality? This book is the first scholarly monograph in English devoted to the philosophical analysis of psychedelic drugs. Its central focus is the apparent conflict between the growing use of psychedelics in psychiatry and the philosophical worldview of naturalism. Within the book, Letheby integrates empirical evidence and philosophical considerations in the service of a simple conclusion: this "Comforting Delusion Objection" to psychedelic therapy fails. While exotic metaphysical ideas do sometimes come up, they are not, on closer inspection, the central driver of change in psychedelic therapy. Psychedelics lead to lasting benefits by altering the sense of self, and changing how people relate to their own minds and lives-not by changing their beliefs about the ultimate nature of reality. The upshot is that a traditional conception of psychedelics as agents of insight and spirituality can be reconciled with naturalism (the philosophical position that the natural world is all there is). Controlled psychedelic use can lead to genuine forms of knowledge gain and spiritual growth-even if no Cosmic Consciousness or transcendent divine Reality exists. Philosophy of Psychedelics is an indispensable guide to the literature for researchers already engaged in the field of psychedelic psychiatry, and for researchers-especially philosophers-who want to become acquainted with this increasingly topical field.

Computer simulations of the formation and evolution of large-scale structure in the universe are integral to the enterprise of modern cosmology. Establishing the reliability of these simulations has been extremely challenging, primarily because of epistemic opacity. In this setting, robustness analysis defined by requiring converging outputs from a diverse ensemble of simulations is insufficient to determine simulation validity. We propose an alternative path of structured code validation that applies eliminative reasoning to isolate and reduce possible sources of error, a potential (...) path that is already being explored by some cosmologists.

The intuitions at the core of environmental ethics and of other neglected value realms put pressure on traditional anthropocentric ethics based on monistic value theories. Such pressure is so severe that it has led many to give up on the idea of monistic value theories altogether. I argue that value monism is still preferable to value pluralism and that, indeed, these new challenges are opportunities to vastly improve impoverished traditional theories. I suggest an alternative monistic theory, Richness Theory, and show (...) how it provides an opportunity to capture the needs of both environmental ethics and of our traditional ethics. (shrink)

Was Swift correct that “reasoning will never make a man correct an ill opinion, which by reasoning he never acquired” (Letter to a Young Gentleman)? If so, what recourse is there to change attitudes especially among those who continue to fervently believe unjustified claims and act upon them in a way that affects other people? I will answer the first question with a qualified yes, and the second I will follow Swift’s implicit proposal to rely upon humor, satire, playful ridicule, (...) and especially irony to unsettle the certainties of those who have not appealed to reason or epistemic justification to maintain their cherished opinions. In the bulk of the chapter, I will then assess what sort of irony Swift employs: is his irony primarily a trope in the service of a particular idea? Or is he truly Socratic in his irony, the sort Kierkegaard admired that transcends the mere rhetorical device and can be viewed as a stance on life in general? The answer to the latter question, in typical Aristotelian fashion, will be yes and no. My account of Socratic Irony will be informed primarily by the works of Alexander Nehemas, Jorge Portilla, and Jonathan Lear’s interpretation of Kierkegaard on Socrates’ irony. (shrink)

It is natural to think that many of our beliefs are rational because they are based on seemings, or on the way things seem. This is especially clear in the case of perception. Many of our mathematical, moral, and memory beliefs also appear to be based on seemings. In each of these cases, it is natural to think that our beliefs are not only based on a seeming, but also that they are rationally based on these seemings—at least assuming there (...) is no relevant counterevidence. This piece is an introduction to a volume dedicated to the question of what the connection is between seemings and justified belief: under what conditions, if any, can a seeming justify its content?

We argue that if there are laws of nature, then there must also be accidents. If the “laws” in a world suffice to determine the world’s entire history, then these “laws” cannot play various central roles characteristic of laws, and thus (we conclude) they are not laws at all. Many proposed accounts of lawhood (primitivist accounts, universals accounts, the Best System Account, the Package Deal Account, essentialist accounts) inappropriately permit worlds with laws but no accidents. We identify two otherwise dissimilar (...) accounts that correctly (on our view) deem such worlds impossible; one is Humean and the other is non-Humean. (shrink)

This paper responds to a new objection, due to Ben Bramble, against attitudinal theories of sensory pleasure and pain: the objection from unconscious pleasures and pains. According to the objection, attitudinal theories are unable to accommodate the fact that sometimes we experience pleasures and pains of which we are, at the time, unaware. In response, I distinguish two kinds of unawareness and argue that the subjects in the examples that support the objection are unaware of their sensations in only a (...) weak sense, and this weak sort of unawareness of a sensation does not preclude its being an object of one’s attitudes.

Starting from two observations regarding nursing ethics research in the past two decades, namely, the dominant influence of both the empirical methods and the principles approach, we present the cornerstones of a foundational argument-based nursing ethics framework. First, we briefly outline the general philosophical–ethical background from which we develop our framework. This is based on three aspects: lived experience, interpretative dialogue, and normative standard. Against this background, we identify and explore three key concepts—vulnerability, care, and dignity—that must be observed in (...) an ethical approach to nursing. Based on these concepts, we argue that the ethical essence of nursing is the provision of care in response to the vulnerability of a human being in order to maintain, protect, and promote his or her dignity as much as possible.

We commonly say that some evidence supports a hypothesis or that some premise evidentially supports a conclusion. Both internalists and externalists attempt to analyze this notion of evidential support, and the primary purpose of this paper is to argue that reliabilist and proper functionalist accounts of this relation fail. Since evidential support is one component of inferential justification, the upshot of this failure is that their accounts of inferential justification also fail. In Sect. 2, I clarify the evidential support relation. (...) In Sects. 3–5, I subject reliabilist and proper functionalist accounts of evidential support to various counterexamples. In Sect. 6, I show that the most promising ways to address these counterexamples aren’t very promising. (shrink)

The Neo-Moorean Deduction (I have a hand, so I am not a brain-in-a-vat) and the Zebra Deduction (the creature is a zebra, so isn’t a cleverly disguised mule) are notorious. Crispin Wright, Martin Davies, Fred Dretske, and Brian McLaughlin, among others, argue that these deductions are instances of transmission failure. That is, they argue that these deductions cannot transmit justification to their conclusions. I contend, however, that the notoriety of these deductions is undeserved. My strategy is to clarify, attack, defend, (...) and apply. I clarify what transmission and transmission failure really are, thereby exposing two questionable but quotidian assumptions. I attack existing views of transmission failure, especially those of Crispin Wright. I defend a permissive view of transmission failure, one which holds that deductions of a certain kind fail to transmit only because of premise circularity. Finally, I apply this account to the Neo-Moorean and Zebra Deductions and show that, given my permissive view, these deductions transmit in an intuitively acceptable way—at least if either a certain type of circularity is benign or a certain view of perceptual justification is false.

Calling someone fat is not only cruel and unkind—it also subordinates them. While the sharpest and most immediate harms of fatphobic bullying are emotional and psychological, these vary according to the resilience of the target. What one person can laugh off, another feels deeply, perhaps for years. But ‘fat-calling’ does not only have individual harms—it also perpetuates a subordinating social structure ranking fat people as inferior. Despite recent work on obesity and fatphobia, the conversational dynamics of ascribing fatness to someone (...) else (rather than oneself) are relatively unexplored, especially in philosophy. This paper argues that fat-calling assigns its target a subordinate discourse role, constraining their subsequent conversational behaviour and permitting further discriminatory behaviour from interlocutors. And these conversational norm-changes alter the initial permissibility conditions of future conversations to the detriment of fat people. This is not to say that fat-calling is morally equivalent to slurs and hate speech—but it does show that it leverages similar conversational mechanisms to entrench injustice. (shrink)

The Oxford Handbook of the History of Physics brings together cutting-edge writing by more than twenty leading authorities on the history of physics from the seventeenth century to the present day. By presenting a wide diversity of studies in a single volume, it provides authoritative introductions to scholarly contributions that have tended to be dispersed in journals and books not easily accessible to the general reader. While the core thread remains the theories and experimental practices of physics, the Handbook contains (...) chapters on other dimensions that have their place in any rounded history. These include the role of lecturing and textbooks in the communication of knowledge, the contribution of instrument-makers and instrument-making companies in providing for the needs of both research and lecture demonstrations, and the growing importance of the many interfaces between academic physics, industry, and the military.

Teaching Internship is an integral journey for pre-service teachers, providing a platform to apply academic knowledge in the workplace. However, emotional experiences are prevalent during the internship, posing challenges for pre-service teachers. Consequently, this study aims to understand the emotional experiences of pre-service teachers during their internship and assess how it impacts their performance. The current study employed a qualitative method, adhering to a multiple case study design. Ten (10) fourth-year elementary pre-service teachers from Immaculate Conception College of Balayan Inc. (...) were selected using purposive sampling technique. Then thematic analysis was utilized to analyze the data. Results revealed that participants experienced both positive and negative emotional experiences that challenge their self-confidence, time management, teaching abilities, and relationship with cooperating teachers and students. These results indicate that emotional experiences are highly evident during teaching internship. With this, the suggested advocacy plan in this study proposes interventions such as seminars, workshops, and tours to enhance the emotional resilience, emotional support, and emotional management of pre-service teachers. Furthermore, future research is advised to utilize diverse methodological techniques and include a larger sample of pre-service teachers from various majors to encompass broader perspectives on the discussed topic, building upon the findings of the current study.

A short encyclopedia entry on the issue of whether the value of a whole is equal to the sum of the values of its parts.

Frustration has been growing with mainstay epistemological methods of logical deduction and experimental falsification for assessing theories of consciousness. This paper explores one among several alternatives being proposed: the listed requirements epistemology. A literature search identifies five papers that explicitly list requirements for assessing consciousness theories. These five lists are analysed as a promising starting point, but as yet insufficiently comprehensive to do the method justice. The longest list has 11 items, but 19 unique items are identified across the five (...) lists and a taxonomic analysis by category further surfaces at least 30 potential candidates. Four limitations of the method are discussed, arguing that it is best treated as one practical tool as part of a broader strategy for rigorously assessing consciousness theories and identifying avenues for future research. The conclusion describes a workplan for a sufficiently complete working taxonomy to support the field’s collective endeavours. (shrink)

The metaphor of weighing reasons brings to mind a single (double-pan balance) scale. The reasons for φ go in one pan and the reasons for ~φ go in the other. The relative weights, as indicated by the relative heights of the two pans of the scale, determine the deontic status of φ. This model is simple and intuitive, but it cannot capture what it is to weigh reasons correctly. A reason pushes the φ pan down toward permissibility (has justifying weight) (...) only insofar as it pushes the ~φ pan up toward impermissibility (has requiring weight). Thus, Single Scale is committed to Single Proportion (first pass): all reasons have the same proportion of justifying and requiring weight. Many normative theories reject Single Proportion, and they are not thereby confused about how to weigh reasons. One can be mistaken about the weight of a reason without being confused about how reasons are to be weighed. Single Scale is problematic, not because it appeals to the image of a scale, but because it appeals to the image of a single scale. We need two scales to capture what it is to weigh reasons correctly. (shrink)

This volume is the first systematic presentation of the work of Albert Einstein, comprising fourteen essays by leading historians and philosophers of science that introduce readers to his work. Following an introduction that places Einstein's work in the context of his life and times, the book opens with essays on the papers of Einstein's 'miracle year', 1905, covering Brownian motion, light quanta, and special relativity, as well as his contributions to early quantum theory and the opposition to his light quantum (...) hypothesis. Further essays relate Einstein's path to the general theory of relativity (1915) and the beginnings of two fields it spawned, relativistic cosmology and gravitational waves. Essays on Einstein's later years examine his unified field theory program and his critique of quantum mechanics. The closing essays explore the relation between Einstein's work and twentieth-century philosophy, as well as his political writings. (shrink)

This paper is an enquiry into the logical, metaphysical, and physical possibility of time travel understood in the sense of the existence of closed worldlines that can be traced out by physical objects. We argue that none of the purported paradoxes rule out time travel either on grounds of logic or metaphysics. More relevantly, modern spacetime theories such as general relativity seem to permit models that feature closed worldlines. We discuss, in the context of Gödel's infamous argument for the ideality (...) of time based on his eponymous spacetime, what this apparent physical possibility of time travel means. Furthermore, we review the recent literature on so-called time machines, i.e., of devices that produce closed worldlines where none would have existed otherwise. Finally, we investigate what the implications of the quantum behaviour of matter for the possibility of time travel might be and explicate in what sense time travel might be possible according to leading contenders for full quantum theories of gravity such as string theory and loop quantum gravity.

This paper begins by taking seriously former slave and abolitionist Frederick Douglass’ response in his What to the Slave is the Fourth of July? to systematic violence and oppression. He claims that direct argumentation is not the ideal mode of resistance to oppression: “At a time like this, scorching irony, not convincing argument, is needed.” I will focus on a few elements of this playful mode of resistance that conflict with the more straightforward strivings for abstract, universal, objective, convergent, absolute (...) thinking that champions reason over emotion, logic over narrative, and science over lived experience. In contrast, the type of protest employed by people like Douglass can utilize aesthetics and logic, playfulness and seriousness, emotion, even anger, and reason. Douglass provides examples of humorous, sincere parrhesia, oscillating between the lexicon of the dominant sphere and the critical reflection from a trickster on the margins. This will require an analysis of Michel Foucault’s conception of parrhesia: courageous truth-telling in the face of powerful people or institutions. It is a study of humor in the parrhesiastes, an element I think neglected by Foucault. I argue that the humorous parrhesiastes offers a mode of resistance which can subvert oppressive power structures that perpetuate injustice, revealing the fact that humor can be integral in courageous truth-telling.

“Classic”, serotonergic psychedelic drugs such as LSD and psilocybin are the objects of renewed attention in science and psychiatry. A recent spate of research has produced evidence that psychedelics might be safe and effective adjuncts to the treatment of mood and addictive disorders, agents of positive psychological change in healthy subjects, and valuable tools for studying the neural mechanisms of perception and cognition. This chapter surveys three philosophical debates that have arisen in response to this “renaissance” of psychedelic research. The (...) first concerns the mechanisms of psychedelic-assisted psychotherapy (“psychedelic therapy”): How, exactly, does psychedelic administration in controlled conditions cause lasting psychological benefits? The second concerns the implications of psychedelic research for the philosophy of mind: Does psychedelic evidence show that there can be conscious mental states lacking all forms of self-consciousness? The third concerns the epistemic status of the psychedelic state: Is it possible that certain kinds of knowledge, or other epistemic benefits, could be gained by undergoing a psychedelic experience?

Philosophers often treat racist and sexist slurs as a special sort of puzzle. What is the difference between a slur and its correlates? In attempting to answer this question, a second distinction has been overlooked: that between slurs and insults. What makes a term count as a slur? This is not an unnecessary taxonomical question as long as ableist terms such as ‘moron’ are dismissed as mere insults. Attempts to resolve the insult/slur distinction by considering the communicative content of slurs (...) are not promising. A better solution is offered by speech act theory, and this paper develops a novel way to describe ordinary slurring utterances as oppressive speech acts. This can both explain the difference between slurs and insults, and challenge the dismissal of ableist terms. (shrink)

In two very influential papers from 2008, Tamar Gendler introduced the concept of “alief” to describe the mental state one is in when acting in ways contrary to their consciously professed beliefs. For example, if asked to eat what they know is fudge, but shaped into the form of dog feces, they will hesitate, and behave in a manner that would be consistent with the belief that the fudge is really poop. They alieve that it is disgusting, while they believe (...) it is not. This paper investigates laughter from self-proclaimed egalitarian, tolerant folk, in response to oppressive jokes that might fit the alief-model. If I merely alieve the content of a joke at which I laugh, will that constitute morally exculpating reasons for such laughter? And what else might it imply? This paper will provide insights at the intersections of humor studies, ethics, epistemology, phenomenology, and the philosophy of mind, all while being moderately and appropriately amusing.

In replying to certain objections to the existence of God, Robert Adams, Bruce Langtry, and Peter van Inwagen assume that God can appropriately choose a suboptimal world, a world less good than some other world God could have chosen. A number of philosophers, such as Michael Slote and Klaas Kraay, claim that these theistic replies are therefore committed to the claim that satisficing can be appropriate. Kraay argues that this commitment is a significant liability. I argue, however, that the relevant (...) defenses of theism are committed to the appropriateness of, not satisficing, but motivated submaximization. When one submaximizes with motivation, one aims at the optimum but accepts the good enough because of a countervailing consideration. When one satisfices, one aims at the good enough and chooses the good enough because it realizes her aim at the good enough. While commitment to the appropriateness of satisficing may be a significant liability, commitment to the appropriateness of motivated submaximization is not. (shrink)

Many contemporary philosophers rate error theories poorly. We identify the arguments these philosophers invoke, and expose their deficiencies. We thereby show that the prospects for error theory have been systematically underestimated. By undermining general arguments against all error theories, we leave it open whether any more particular arguments against particular error theories are more successful. The merits of error theories need to be settled on a case-by-case basis: there is no good general argument against error theories.

This chapter provides an account of what dogmatism is, why the term matters, and how it applies to withholding judgment. Roughly, a person is dogmatic about P when a certain problematic personal investment—a superiority complex, broadly construed—biases their judgment concerning whether P. The term dogmatism and its cognates matter because of their social function. To accuse you of dogmatism is to signal how you are to be treated: your judgment or behavior needs to be “brought down to earth,” so that (...) you have a more accurate view of yourself or so you stop treating others as less important or less than. Withholding judgment can be dogmatic in the same way that belief is dogmatic. Belief (withholding) is dogmatic just when the relevant problematic personal investment results in biases that keep a person stuck in that belief (withholding). (shrink)

In the Western philosophical tradition, the earliest recognized paradoxes are attributed to Zeno of Elea (ca. 490–430 B.C.E.) and to Eubulides of Miletus (fl. 4th century B.C.E.). In the Chinese tradition, the earliest and most well-known paradoxes are ascribed to figures associated with the “School of Names” (ming jia 名家), a diverse group of Warring States (479–221 B.C.E.) thinkers who shared an interest in language, logic, and metaphysics. Their investigations led some of these thinkers to propound puzzling, paradoxical statements such (...) as “Today go to Yue but arrive yesterday,” “White horses are not horses,” and “Mountains and gorges are level.” Such paradoxes seem to have been intended to highlight fundamental features of reality or subtleties in semantic relations between words and things. Why were thinkers who advanced paradoxes categorized as a school of “names”? In ancient China, philosophical inquiry concerning language and logic focused on the use of “names” (ming 名, also terms, labels, or reputation) and their semantic relations to “stuff” (shi 實, also objects, features, events, or situations). Hence for classificatory purposes, second-century B.C.E. Han-dynasty archivists grouped together assorted pre-Han figures whose most prominent ideas seemed to concern the relation between names and stuff—or at least strange, unorthodox uses of names—and dubbed them a school or lineage (jia 家) devoted to the study of names. Unfortunately, both the label and the grouping are misleading. Historically, the school was a retrospective, taxonomical fiction. The figures classified under the “School of Names” never formed a distinct circle, movement, tradition, or line of influence devoted to any particular doctrine, theme, method, or way of life. Their intellectual interests overlapped at most only partly, while also overlapping extensively with those of texts associated with other schools or traditions, such as the Mohist “Dialectics” 墨辯, the Zhuangzi 莊子, the Xunzi 荀子, and the Annals of Lü Buwei 呂氏春秋. What perhaps does set the School of Names apart is that some (though not all) of the figures associated with it apparently delighted in propounding paradoxical or preposterous sayings, while the other texts just mentioned generally (though not exclusively) seek to explain and debunk such utterances.

Knowledge is an achievement manifesting a type of competence, akin in important respects to a skill. Accordingly, epistemic judgment is an exercise of agency. Ernest Sosa’s work has elaborated these and related insights into a meticulous, persuasive version of a virtue epistemology. Given the framing assumptions of mid-twentieth century Anglo-American epistemology, developing a competence-centered explanation of judgment, knowledge, and justification required brilliant critical and creative thought. So it is intriguing and perhaps instructive to consider how some of Sosa’s views relate (...) to the outlook of early Chinese thinkers, for whom the idea of knowledge as a competent performance required no argument, being implicitly taken as an obvious, shared starting point. Here I will focus on Xúnzǐ 荀子, whose epistemological concerns in some respects dovetail with and in others complement Sosa’s. I will draw on concepts from Sosa’s framework to elucidate features of Xúnzǐ’s epistemology and in turn suggest how Xúnzǐ’s theoretical orientation might cast light on Sosa’s project. In particular, I will suggest that Sosa’s conception of full aptness helps to elucidate the significance of Xúnzǐ’s discussion of epistemic pitfalls, while Xúnzǐ’s treatment of the epistemic agent’s awareness of and commitment to norms of judgment helps to enrich Sosa’s view of epistemic agency.

Psychedelic ingestion and meditative practice are both ancient methods for altering consciousness that became widely known in Western society in the second half of the 20th century. Do the similarities begin and end there, or do these methods – as many have claimed over the years – share some deeper common elements? In this chapter I take a neurophilosophical approach to this question and argue that there are, indeed, deeper commonalities. Recent empirical studies show that psychedelics and meditation modulate overlapping (...) brain networks involved in the sense of self, salience, and attention; moreover, psychedelics can occasion lasting increases in “mindfulness-related capacities” for taking a non-reactive stance on one’s inner experience (e.g. Sampedro et al. 2017). The self-binding theory of psychedelic ego dissolution (Letheby and Gerrans 2017) offers a plausible explanation of these findings: by disrupting self-related beliefs implemented in high-level cortical networks, both psychedelics and meditation can “unbind” mental contents from one’s self-model, moving these contents along the continuum from phenomenal transparency to opacity (cf. Metzinger 2003). In other words, both psychedelics and meditation can expose and weaken our foundational beliefs about our own identity, allowing us to disidentify with these beliefs and see them as “just thoughts”. There are connections between these ideas and recent arguments suggesting that psychedelic use may have epistemic benefits consistent with philosophical naturalism (Letheby 2015, 2016, 2019). I conclude with a proposal: these connections may help in thinking about the putative epistemic benefits of meditation practice from a naturalistic perspective. (shrink)

Although the ‘metaverse’ is still the feverish pipedream of tech companies and venture capitalists, it is also a powerful imaginary for channelling enormous resources towards deepening and extending ongoing processes of digitalization and datafication. It is thus likely that an increasing amount of human activity – both professional as well as leisure-related – will take place in metaversal spaces, and that the paradigm of ‘Big Data’ is about to be expanded with massive amounts of new and varied or multimodal data (...) that capture even more (corporeal, sensorial, spatial, and temporal) information produced by and about people as well as their interactions as these unfold in (mixed) spaces over time. Much like the rise of big data, the emergence of metaversal data gives rise to important tensions and issues. From the perspective of critical data studies, media studies, and science and technology studies, this paper spotlights the role of data obtained about, in, and through metaverse technologies and environments as well as how this can be understood as both an intensification and extension of the datafication of social life, the quantification of research methodologies, and the exacerbation of social inequality. We discuss these issues through a series of six provocations that each address a distinct tension between metaverse data, the production of knowledge, research methodologies, and various social issues that are central to the datafication of contemporary societies.

According to the thesis of doxastic wronging, we can wrong people in virtue of having certain beliefs about them. In this chapter, I motivate and defend a similar view, the thesis of suspensive wronging, that we can wrong people in virtue of bearing an indecision attitude towards certain questions that bear on certain people. I explore the extent to which the thesis of suspensive wronging fits with certain prominent conceptions of suspension of judgment, including the sui generis attitude, higher-order, and (...) credence views, and argue that it aligns with each of them. I then argue that reflection on cases of suspensive wronging reveals that the common characterization of suspension of judgment as a kind of ‘neutrality’ is nevertheless problematic, arguing that we should distinguish between attitudinal neutrality and property neutrality—i.e., neutrality on the truth of an answer to a question vs. the neutrality of the properties of the attitude that responds to a question, which accommodates the sense in which 'being neutral' in a debate can sometimes be unjust but also still a genuine sort of neutrality. Finally, I consider whether widespread views about the involuntariness of belief and the right-kind of reasons for belief refutes the suspensive wronging thesis, arguing that this is not the case, concluding with some reflections on the relationship between the suspensive wronging thesis and moral encroachment on suspension of judgment.

Just as theory of representation is deficient if it can’t explain how misrepresentation is possible, a theory of computation is deficient if it can’t explain how miscomputation is possible. Nonetheless, philosophers have generally ignored miscomputation. My primary goal in this paper is to clarify both what miscomputation is and how to adequately explain it. Miscomputation is a special kind of malfunction: a system miscomputes when it computes in a way that it shouldn’t. To explain miscomputation, you must provide accounts of (...) computational behavior, computational norms, and how computational behavior can deviate from computational norms. A secondary goal of this paper is to defend an (quasi-)individualist, mechanistic theory of miscomputation. Computational behavior is narrowly individuated. Computational norms are widely individuated. A system miscomputes when its behavior manifests a narrow computational structure that the widely individuated norms say that it should not have. (shrink)
