We show that the velocity distribution in rarefied (i.e., Knudsen) gases is spontaneously weighted in favor of small speeds away from the Maxwellian distribution corresponding to the temperature of the container walls—despite thermodynamic equilibrium with the walls. The consequent paradox concerning the second law of thermodynamics is discussed.

This innovative text is psychologically informed, both in its diagnosis of inferential errors, and in teaching students how to watch out for and work around their natural intellectual blind spots. It also incorporates insights from epistemology and philosophy of science that are indispensable for learning how to evaluate premises. The result is a hands-on primer for real world critical thinking. The authors bring a fresh approach to the traditional challenges of a critical thinking course: effectively explaining the nature of validity, (...) assessing deductive arguments, reconstructing, identifying and diagramming arguments, and causal and probabilistic inference. Additionally, they discuss in detail, important, frequently neglected topics, including testimony, including the evaluation of news and other information sources, the nature and credibility of science, rhetoric, and dialectical argumentation. The treatment of probability uses frequency trees and a frequency approach more generally, and argument reconstruction is taught using argument maps; these methods have been shown to improve students’ reasoning and argument evaluation.

Two lines of evidence indicate that there exists a reciprocal inhibitory relationship between opposed brain networks. First, most attention-demanding cognitive tasks activate a stereotypical set of brain areas, known as the task-positive network and simultaneously deactivate a different set of brain regions, commonly referred to as the task negative or defaultmode network. Second, functional connectivity analyses show that these same opposed networks are anti-correlated in the resting state. Wehypothesize that these reciprocally inhibitory effects reflect two incompatible cognitive modes, each of (...) which may be directed towards understanding the external world. Thus, engaging onemode activates one set of regions and suppresses activity in the other.Wetest this hypothesis by identifying two types of problem-solving task which, on the basis of prior work, have been consistently associated with the task positive and task negative regions: tasks requiring social cognition, i.e., reasoning about the mental states of other persons, and tasks requiring physical cognition, i.e., reasoning about the causal/mechanical properties of inanimate objects. Social and mechanical reasoning tasks were presented to neurologically normal participants during fMRI. Each task type was presented using both text and video clips. Regardless of presentation modality, we observed clear evidence of reciprocal suppression: social tasks deactivated regions associated with mechanical reasoning and mechanical tasks deactivated regions associated with social reasoning. These findings are not explained by self-referential processes, task engagement, mental simulation,mental time travel or external vs. internal attention, all factors previously hypothesized to explain default mode network activity. Analyses of resting state data revealed a close match between the regions our tasks identified as reciprocally inhibitory and regions of maximal anti-correlation in the resting state. These results indicate the reciprocal inhibition is not attributable to constraints inherent in the tasks, but is neural in origin. Hence, there is a physiological constraint on our ability to simultaneously engage two distinct cognitive modes. Furtherwork is needed tomore precisely characterize these opposing cognitive domains.

Can beliefs that are not consciously formulated serve as part of an agent's evidence for other beliefs? A common view says no, any belief that is psychologically immediate is also epistemically immediate. I argue that some unconscious beliefs can serve as evidence, but other unconscious beliefs cannot. Person-level beliefs can serve as evidence, but subpersonal beliefs cannot. I try to clarify the nature of the personal/subpersonal distinction and to show how my proposal illuminates various epistemological problems and provides a principled (...) framework for solving other problems.

In this paper, I argue that all expressions for abstract objects are meaningless. My argument closely follows David Lewis’ argument against the intelligibility of certain theories of possible worlds, but modifies it in order to yield a general conclusion about language pertaining to abstract objects. If my Lewisian argument is sound, not only can we not know that abstract objects exist, we cannot even refer to or think about them. However, while the Lewisian argument strongly motivates nominalism, it also undermines (...) certain nominalist theories. (shrink)

Many contemporary Anglo-American philosophers describe themselves as naturalists. But what do they mean by that term? Popular naturalist slogans like, "there is no first philosophy" or "philosophy is continuous with the natural sciences" are far from illuminating. "Understanding Naturalism" provides a clear and readable survey of the main strands in recent naturalist thought. The origin and development of naturalist ideas in epistemology, metaphysics and semantics is explained through the works of Quine, Goldman, Kuhn, Chalmers, Papineau, Millikan and others. The most (...) common objections to the naturalist project - that it involves a change of subject and fails to engage with "real" philosophical problems, that it is self-refuting, and that naturalism cannot deal with normative notions like truth, justification and meaning - are all discussed. "Understanding Naturalism" distinguishes two strands of naturalist thinking - the constructive and the deflationary - and explains how this distinction can invigorate naturalism and the future of philosophical research.

Cases of past absence involve agents noticing in retrospect that an object or property was absent, such as when one notices later that a colleague was not at a talk. In Sanskrit philosophy, such cases are introduced by Kumārila as counterexamples to the claim that knowledge of absence is perceptual, but further take on a life of their own as a topic of inquiry among Kumārila’s commentators and their Nyāya interlocutors. In this essay, I examine the Nyāya philosopher Gaṅgeśa’s epistemology (...) of past absence, according to which agents learn that a recollectable object or property was absent by inferring its past absence from failing to recall that object or property. Gaṅgeśa’s account is best appreciated against the backdrop of earlier theories and their shortcomings, and I begin by presenting historical views leading up to his. I identify two groups of views about the epistemology of past absence: recollection views, according to which cases of past absence involve agents recalling negative information; and recollection failure views, according to which cases of past absence involve agents failing to recall positive information. I reconstruct two early recollection views: a Bhāṭṭa view belonging to Uṃveka, and a competing Nyāya view belonging to Jayanta and Bhāsarvajña. I then examine Śālikanātha and Sucarita’s critiques of recollection views, following which I reconstruct a Bhāṭṭa recollection failure view belonging to Pārthasārathi. I then examine Gaṅgeśa’s critiques of Pārthasārathi’s account and the recollection failure view he constructs out of its shortcomings. (shrink)

It is sometimes said that there are two, competing versions of W. V. O. Quine’s unrelenting empiricism, perhaps divided according to temporal periods of his career. According to one, logic is exempt from, or lies outside the scope of, the attack on the analytic-synthetic distinction. This logic-friendly Quine holds that logical truths and, presumably, logical inferences are analytic in the traditional sense. Logical truths are knowable a priori, and, importantly, they are incorrigible, and so immune from revision. The other, radical (...) reading of Quine does not exempt logic from the attack on analyticity and a priority. Logical truths and inferences are themselves part of the web of belief, and the same global methodology applies to logic as to any other part of the web, such as theoretical chemistry or ordinary beliefs about ordinary objects. Everything, including logic, is up for grabs in our struggle for holistic confirmation. The purpose of this paper is to examine the law of non-contradiction, and the concomitant principle of ex falso quodlibet, from the perspective of the principles advocated by the radical Quine. I show that he has no compelling reason to accept either of these. To put it bluntly, neither the law of non-contradiction nor the rule of ex falso quodlibet is empirically confirmed, and these principles fare poorly on the various criteria for theory acceptance on the methodology of the radical Quine. So the radical Quine is led rather quickly and rather directly into something in the neighborhood of Graham Priest’s dialetheism. (shrink)

In exploring the intra-active, relational and material connections between humans and non- humans, proponents of posthumanism advocate a questioning of the ‘human’ beyond its traditional anthropocentric conceptualization. By referring specifically to controversial developments in mHealth applications, this paper critically diverges from posthuman accounts of human/non-human assemblages. Indeed, we argue that, rather than ‘dissolving’ the human subject, the power of assemblages lie in their capacity to highlight the antagonisms and contradictions that inherently affirm the importance of the subject. In outlining this (...) claim, we propose a turn from the posthuman to the inhuman as a way of understanding the contemporary landscape of (digital) health. (shrink)

This article develops a fairness-based criticism of the UK’s policy of promoting free admissions at major museums. With a focus on geographic inequalities and per-capita museums spending, I argue that free admissions can be a surprisingly bad way of promoting cultural opportunities for disadvantaged groups. My criticism emphasises the fact that free admissions consume resources without necessarily providing targeted benefits to disadvantaged groups and addressing background inequalities. Given that museums vary in their location, visitor profile, and operating costs, this critique (...) does not apply to all museums. It applies to the largest and most popular museums in the most advantaged areas, which can expect to keep drawing significant numbers while charging. If we are aiming to prioritise the interests of less advantaged groups, we should be in favour of charging at London’s major museums, to finance “levelling up” across regions, and more direct access-promoting measures in targeted outreach, collaboration, and programming.

The term ‘reflexivity’ continues to maintain an interpretive hegemony in discussions on modernity and the Self. As a form of praxis, applications of reflexivity frequently rely upon an acknowledged awareness of one’s self-conscious attitudes, dispositions, behaviors and motives. This paper will take aim at such contentions, exploring the extent to which examples of racism rely upon a level of reflexivity, best encapsulated in Žižek’s ‘reflexive racism’. Specifically, it is highlighted how examples of non- racism/anti-racism assert the formal promotion of a (...) monadic subject, solely adept at ‘uncovering’ and ‘relinquishing’ their racism (disavowal); and, an equally unhelpful social constructionism, which depoliticizes racism by relocating and relativizing it to a particular socio-historical context (deferment). In outlining this response, specific attention is given to Lacan’s subject of enunciation and subject of the enunciated, from which it is concluded that it is in the obfuscation of one’s ‘position of enunciation’ that examples of reflexive racism reside.

Self-driving cars promise solutions to some of the hazards of human driving but there are important questions about the safety of these new technologies. This paper takes a qualitative social science approach to the question ‘how safe is safe enough?’ Drawing on 50 interviews with people developing and researching self-driving cars, I describe two dominant narratives of safety. The first, safety-in-numbers, sees safety as a self-evident property of the technology and offers metrics in an attempt to reassure the public. The (...) second approach, safety-by-design, starts with the challenge of safety assurance and sees the technology as intrinsically problematic. The first approach is concerned only with performance—what a self-driving system does. The second is also concerned with why systems do what they do and how they should be tested. Using insights from workshops with members of the public, I introduce a further concern that will define trustworthy self-driving cars: the intended and perceived purposes of a system. Engineers’ safety assurances will have their credibility tested in public. ‘How safe is safe enough?’ prompts further questions: ‘safe enough for what?’ and ‘safe enough for whom?’. (shrink)

Biology lacks a central organism concept that unambiguously marks the distinction between organism and non-organism because the most important questions about organisms do not depend on this concept. I argue that the two main ways to discover useful biological generalizations about multicellular organization—the study of homology within multicellular lineages and of convergent evolution across lineages in which multicellularity has been independently established—do not require what would have to be a stipulative sharpening of an organism concept.

In this paper, I inspect the grounds for the mature Spinozist argument for substance monism. The argument is succinctly stated at Ethics Part 1, Proposition 14. The argument appeals to two explicit premises: (1) that there must be a substance with all attributes; (2) that substances cannot share their attributes. In conjunction with a third implicit premise, that a substance cannot not have any attribute whatsoever, Spinoza infers that there can be no more than one substance. I begin the inspection (...) with the analysis of the first premise, which is provided in the form of the four proofs of God’s existence in Ethics Part 1, Proposition 11. While demonstrating how Spinoza adopts a progressive approach, where the fourth proof of God’s existence is more successful and persuasive than the third, which is more successful than the second, etc., I also unpack concepts central to Spinoza’s thinking here, including the concepts of reason (ratio) and power (potesta or potentia). I then analyze the second premise of the Spinozist argument for substance monism, as established by Ethics Part 1, Proposition 4 in conjunction with Ethics Part 1, Proposition 5. I take up and respond to the objection attributed to Leibniz that a substance p can have the attributes x and y and a substance q can have the attributes y and z, and thus that substances can share some attributes while remaining distinct. Throughout the study, my attention is focused on the argumentative procedures Spinoza adopts. This yields a close, internalist reading of the text where Spinoza effectively embraces substance monism. In conclusion to this study, I underscore to the originality of Spinoza’s argument for seventeenth century theories of substance. (shrink)

We question the usefulness of Pylyshyn's dichotomy between cognitively penetrable and cognitively impenetrable mechanisms as the basis for his distinction between cognition and early vision. This dichotomy is comparable to others that have been proposed in psychology prompting disputes that by their very nature could not be resolved. This fate is inevitable for Pylyshyn's thesis because of its reliance on internal representations and their interpretation. What is more fruitful in relation to this issue is not a difficult dichotomy, but a (...) different look at perception such as proposed by Gibson (1979). (shrink)

At the core of pragmatism is the idea of an active projection of experience into the future. William James’s contribution to pragmatism included an emphasis on emotions in the apprehension of possible futures and related processes. After presenting a summary of Jamesian pragmatism, and especially the significance of emotions in it, the article notes the reception of James’s writings in Europe and their influence on European intellectual developments. Max Weber, for instance, studied James closely. He treated James’s approach to religion (...) as a negative example. While Emile Durkheim rejected the individualist approach of James, he nevertheless found much of value in James’s conceptualization of religious experience, including its emotional underpinnings. Discussion below explores the neglected Jamesian quality of Durkheim’s account of religion. It is noted in conclusion that the more recent sociological neglect of James and the failure to appreciate his particular approach in pragmatism, coincided with the rise of Freudian psychology in the early decades of the twentieth century.

While self-interest is depreciated in Confucian ethics the processes of family relations in traditional China are animated by the self-interested actions of family members. The paper outlines the Confucian ideology of filial piety which is commensurate with the governance of family life organized hierarchically and through the senior male's management of the joint-family's collective property. The structure, operations and principles of membership in traditional Chinese families are indicated, highlighting the tensions within them between consanguinity and conjugality and their material bases. (...) The differential operation of self-interested actions by husbands and wives is also presented. A non-Confucian model of the relational-self is outlined in which both the collective context of Chinese families and the self-interested actions of individual family members within them is explicated.

This is a brief philosophical introduction to, and an annotated translation of, the section on absence from Śālikanātha’s Pramāṇapārāyaṇa (Study of the Instruments of Knowledge), a foundational work of Prābhākara epistemology. In this section, which focuses on the epistemology of absence, Śālikanātha argues against the Bhāṭṭa view that there is a sui generis instrument of knowledge (pramāṇa) by which we learn of absence (abhāva). He does so by arguing for a subjective reductionist thesis about absence, according to which the absence (...) of a perceivable (dṛśya) object at a locus is identical with a positive state of awareness (buddhi) whose content includes the locus but not the perceivable object. If correct, Śālikanātha argues, we should therefore learn of absence in the same ways we acquire self-knowledge more generally. While developing his reductionism about absence, Śālikanātha responds to a range of concerns, including the objection that his view cannot explain causation by absence. (shrink)

Most philosophers treat ontological dependence and metaphysical dependence as distinct relations. A number of key differences between the two relations are usually cited in support of this claim: ontological dependence's unique connection to existence, differing respective connections to metaphysical necessitation, and a divergence in their formal features. Alongside reshaping some of the examples used to maintain the distinction between the two, I argue that the additional resources offered by the increased attention the notion of grounding has received in recent years (...) potentially offer us a way to unite the two relations, promising the attendant benefits parsimony offers, as a result.

The central tradition of mainline economics deals with one way of making a living; producing goods and services. But there is another way of getting ahead through conflict or the 'dark side', by appropriating what others have produced. Parallel to military aggression and resistance, the dark side includes non-military activities such as litigation, strikes and lockouts, takeover contests, and bureaucratic back-biting struggles. This volume brings the analysis of conflict into the mainstream of economics. Part I explores the causes, conduct, and (...) consequences of conflict as an economic activity. Part II delves deeply into the evolutionary sources of our capacities, physical and mental, for both conflict and cooperation. The introductory chapter of the volume, which outlines the significance of the dark side, was the author's 1993 Presidential Address to the Western Economic Association. Other chapters investigate economic models, historical discussions, experimental tests, and applications to topics in political science and law. (shrink)

Academic file-sharing services encourage students to upload materials, sometimes their own study notes for example, but can also include copyrighted university documents, in exchange for access to downloading resources from a common repository. In this process, the lines between legitimate study help and academic misconduct are unclear. Integrity-based strategies to combat these transactions have been limited. Removal by copyright mechanisms has been identified as a potential approach but has been hampered by the enormity of the task and the resource intensity (...) required to make an impact at scale. This explorative study at a large Australian university sought to remove a percentage of copyrighted material from two commonly used academic file-sharing websites and to understand the experience of users in uploading files. Findings from the study were encouraging and informative, resulting in a suite of initiatives being introduced across the institution to prevent uploading in the first instance as well as, where possible, addressing misconduct when it occurred. Limitations included that the study was only undertaken as one university and therefore does not represent the contexts of different institutions. Further, it only investigated two websites out of many available. Future research could explore the use of artificial intelligence (AI) by academic file-sharing services to retain existing users and attract new ones. This work provides a clearer picture of how an institution’s copyrighted material is hosted on two academic file-sharing websites and offers an effective and potentially scalable copyright approach that could be adapted by other higher education institutions.

Às vezes o naturalismo é apresentado como uma visão de mundo geral. Na maioria das vezes quando o naturalismo é assim apresentado, ele é identificado com o fisicalismo: a visão de que tudo é físico ou em algum sentido dependente do que é físico. Mas o fisicalismo enfrenta um problema muito sério e bastante conhecido, o dilema de Hempel. O problema pode ser colocado do seguinte modo: quando dizemos que tudo é físico, o que fazemos é utilizar o termo “físico” (...) como é concebido pelo fisicalismo. Significamos o físico em termos da física atual? Se sim, então essa visão é provavelmente falsa. Esperamos que a física atual possa ser revisada assim como a ciência, a qual se desenvolve em caminhos desconhecidos, e, assim, algumas das reivindicações atualmente aceitas pelos físicos possam ser rejeitadas como falsas no futuro. Queremos com isso alguma física futuramente idealizada? Desde que não temos ideia do que essa física futuramente idealizada seja, não temos uma ideia real de qual é o conteúdo que o fisicalismo deve ter sob tal definição. Se nos dizem que física aqui significa apenas a disciplina que abarca todos os fatos dos quais todos os outros fatos são dependentes, então as reivindicações do fisicalismo são tautológicas.

In this paper I discuss the bearing of Hacking’s ideas about Scientific Styles on traditional debates in the philosophy of science concerning rationality and realism. I argue that a kind of deflationary position with regard to realism debates is a natural consequence of Hacking’s claim that styles are self-authenticating. I then go on to argue, using an example of van Fraassen’s, that Hacking should allow a methodological role for realism debates and hence they are not idle, as he has claimed, (...) although their resolution may not be important.
