This article examines the implications of the holonomy interpretation of classical electromagnetism. As has been argued by Richard Healey and Gordon Belot, classical electromagnetism on this interpretation evinces a form of nonseparability, something that otherwise might have been thought of as confined to nonclassical physics. Consideration of the differences between this classical nonseparability and quantum nonseparability shows that the nonseparability exhibited by the classical electromagnetism on the holonomy interpretation is closer to separability than might at first appear.

ON BUBER, like other titles in the Wadsworth Philosopher's Series, offers a concise, yet comprehensive, introduction to this philosopher's most important ideas. Presenting the most important insights of well over a hundred seminal philosophers in both the Eastern and Western traditions, the Wadsworth Philosophers Series contains volumes written by scholars noted for their excellence in teaching and for their well-versed comprehension of each featured philosopher's major works and contributions. These titles have proven valuable in a number of ways. Serving as (...) standalone texts when tackling a philosophers' original sources or as helpful resources for focusing philosophy students' engagements with these philosopher's often conceptually daunting works, these titles have also gained extraordinary popularity with a lay readership and quite often serve as "refreshers" for philosophy instructors.

Ogden spent over forty years attempting "to deal... with the whole of the linguistic problem." This study gives his work an enduring quality which is of particular relevance to late twentieth century linguistics.

Andrew Wayne discusses some recent attempts to account, within a Bayesian framework, for the "common methodological adage" that "diverse evidence better confirms a hypothesis than does the same amount of similar evidence". One of the approaches considered by Wayne is that suggested by Howson and Urbach and dubbed the "correlation approach" by Wayne. This approach is, indeed, incomplete, in that it neglects the role of the hypothesis under consideration in determining what diversity in a body of evidence (...) is relevant diversity. In this paper, it is shown how this gap can be filled, resulting in a more satisfactory account of the evidential role of diversity of evidence. In addition, it is argued that Wayne's criticism of the correlation approach does not indicate a serious flaw in the approach. (shrink)

In _The Company We Keep_, Wayne C. Booth argues for the relocation of ethics to the center of our engagement with literature. But the questions he asks are not confined to morality. Returning ethics to its root sense, Booth proposes that the ethical critic will be interested in any effect on the ethos, the total character or quality of tellers and listeners. Ethical criticism will risk talking about the quality of _this_ particular encounter with _this_ particular work. Yet it (...) will give up the old hope for definitive judgments of "good" work and "bad." Rather it will be a conversation about _many_ kinds of personal and social goods that fictions can serve or destroy. While not ignoring the consequences for conduct of engaging with powerful stories, it will attend to that more immediate topic, What happens to us _as we read_? Who am I, _during the hours of reading or listening_? What is the quality of the life I lead in the company of these would-be friends? Through a wide variety of periods and genres and scores of particular works, Booth pursues various metaphors for such engagements: "friendship with books," "the exchange of gifts," "the colonizing of worlds," "the constitution of commonwealths." He concludes with extended explorations of the ethical powers and potential dangers of works by Rabelais, D. H. Lawrence, Jane Austen, and Mark Twain. (shrink)

Beyond Chance and Credence introduces a new way of thinking of probabilities in science that combines physical and epistemic considerations. Myrvold shows that conceiving of probabilities in this way solves puzzles associated with the use of probability and statistical mechanics.

Landauer’s principle is, roughly, the principle that logically irreversible operations cannot be performed without dissipation of energy, with a specified lower bound on that dissipation. Although widely accepted in the literature on the thermodynamics of computation, it has been the subject of considerable dispute in the philosophical literature. Proofs of the principle have been questioned on the grounds of insufficient generality and on the grounds of the assumption, used in the proofs, of the availability of reversible processes at the microscale. (...) The relevance of the principle, should it be true, has also been questioned, as it has been argued that microscale fluctuations entail dissipation that always greatly exceeds the Landauer bound. In this article Landauer’s principle is treated within statistical mechanics, and a proof of the principle is given that neither relies on neglect of fluctuations nor assumes the availability of thermodynamically reversible processes. In addition, it is argued that microscale fluctuations are no obstacle to approximating thermodynamic reversibility, in the appropriate sense, as closely as one would like. (shrink)

Harvey Brown’s Physical Relativity defends a view, the dynamical perspective, on the nature of spacetime that goes beyond the familiar dichotomy of substantivalist/relationist views. A full defense of this view requires attention to the way that our use of spacetime concepts connect with the physical world. Reflection on such matters, I argue, reveals that the dynamical perspective affords the only possible view about the ontological status of spacetime, in that putative rivals fail to express anything, either true or false. I (...) conclude with remarks aimed at clarifying what is and isn’t in dispute with regards to the explanatory priority of spacetime and dynamics, at countering an objection raised by John Norton to views of this sort, and at clarifying the relation between background and effective spacetime structure.

Quantum information theory has given rise to a renewed interest in, and a new perspective on, the old issue of understanding the ways in which quantum mechanics differs from classical mechanics. The task of distinguishing between quantum and classical theory is facilitated by neutral frameworks that embrace both classical and quantum theory. In this paper, I discuss two approaches to this endeavour, the algebraic approach, and the convex set approach, with an eye to the strengths of each, and the relations (...) between the two. I end with a discussion of one particular model, the toy theory devised by Rob Spekkens, which, with minor modifications, fits neatly within the convex sets framework, and which displays in an elegant manner some of the similarities and differences between classical and quantum theories. The conclusion suggested by this investigation is that Schrödinger was right to find the essential difference between classical and quantum theory in their handling of composite systems, though Schrödinger's contention that it is entanglement that is the distinctive feature of quantum mechanics needs to be modified.

Moral enhancement proposals struggle to be both plausible and ethically defensible while nevertheless interestingly distinct from both cognitive enhancement as well as (mere) moral education. Brian Earp (_Royal Institute of Philosophy Supplement_ 83:415–439, 12 ) suggests that a promising middle ground lies in focusing on the (suitably qualified) use of psychedelics as _adjuncts_ to moral development. But what would such an adjunctive use of psychedelics look like in practice? In this paper, I draw on literature from three areas where techniques (...) for moral development have been discussed: psychotherapy (e.g., Overholser 2010; Burns 1980) education (e.g., Uhl and Lütge, 2018), and AI-assisted enhancement (e.g., Lara and Deckers, _Neuroethics_ 13(3):275–287, 17 ) in order to propose more concrete ways in which to use psychedelics as adjuncts to moral development. It is shown that in each of these areas, we can see that _trusting_ relationships (e.g., Baier 1986; Hawley 2019) between the facilitator and the agent will very plausibly maximize the success of this type of moral enhancement. Finally, I appeal to literature on informed consent for use of psychedelics (e.g., Smith and Sisti, _Journal of Medical Ethics_, 22 ; Johnson et al., _The Journal of Psychopharmacology_ 22(6):603–20, 23 ) and on the therapeutic relationship in psychotherapy (e.g., Dryden and Reeves 2013; Horvath et al. 2011) to outline concrete suggestions for facilitating dimensions of trust most likely to maximize the benefits of (adjunctive) psychedelic moral enhancement. The result is a newly detailed practical proposal for how we might best facilitate moral enhancement by using drugs as adjuncts to moral development. (shrink)

A proof is given, at a greater level of generality than previous 'no-go' theorems, of the impossibility of formulating a modal interpretation that exhibits 'serious' Lorentz invariance at the fundamental level. Particular attention is given to modal interpretations of the type proposed by Bub.

When should I change my mind? What can I believe and what must I doubt? In this new "philosophy of good reasons" Wayne C. Booth exposes five dogmas of modernism that have too often inhibited efforts to answer these questions.

A Bayesian account of the virtue of unification is given. On this account, the ability of a theory to unify disparate phenomena consists in the ability of the theory to render such phenomena informationally relevant to each other. It is shown that such ability contributes to the evidential support of the theory, and hence that preference for theories that unify the phenomena need not, on a Bayesian account, be built into the prior probabilities of theories.

This paper discusses two senses in which a hypothesis may be said to unify evidence. One is the ability of the hypothesis to increase the mutual information of a set of evidence statements; the other is the ability of the hypothesis to explain commonalities in observed phenomena by positing a common origin for them. On Bayesian updating, it is only mutual information unification that contributes to the incremental support of a hypothesis by the evidence unified. This poses a challenge for (...) the view that explanation is a confirmatory virtue that contributes to such incremental support; its advocates must ground it in some relevant difference between humans and a Bayesian agent.

Perhaps no other critical label has been made to cover more ground than "irony," and in our time irony has come to have so many meanings that by itself it means almost nothing. In this work, Wayne C. Booth cuts through the resulting confusions by analyzing how we manage to share quite specific ironies—and why we often fail when we try to do so. How does a reader or listener recognize the kind of statement which requires him to reject (...) its "clear" and "obvious" meaning? And how does any reader know where to stop, once he has embarked on the hazardous and exhilarating path of rejecting "what the words say" and reconstructing "what the author means"? In the first and longer part of his work, Booth deals with the workings of what he calls "stable irony," irony with a clear rhetorical intent. He then turns to intended instabilities—ironies that resist interpretation and finally lead to the "infinite absolute negativities" that have obsessed criticism since the Romantic period. Professor Booth is always ironically aware that no one can fathom the unfathomable. But by looking closely at unstable ironists like Samuel Becket, he shows that at least some of our commonplaces about meaninglessness require revision. Finally, he explores—with the help of Plato—the wry paradoxes that threaten any uncompromising assertion that all assertion can be undermined by the spirit of irony. (shrink)

There is a long tradition of thinking of thermodynamics, not as a theory of fundamental physics, but as a theory of how manipulations of a physical system may be used to obtain desired effects, such as mechanical work. On this view, the basic concepts of thermodynamics, heat and work, and with them, the concept of entropy, are relative to a class of envisaged manipulations. This article is a sketch and defense of a science of manipulations and their effects on physical (...) systems. I call this science thermo-dynamics, or ΘΔcs\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${\Theta \Delta }^{\text{cs}}$$\end{document}, for short, to highlight that it may be different from the science of thermodynamics, as the reader conceives it. An upshot of the discussion is a clarification of the roles of the Gibbs and von Neumann entropies. Light is also shed on the use of coarse-grained entropies. (shrink)

This book outlines and criticises the six main contemporary arguments for scepticism about the role of human enhancements in promoting well-being. It also defends important and concrete ways in which enhancement-permissive policies should be embraced with the aim of promoting well-being.

In Chapter 3 of True Enough, Elgin outlines her view of objectual understanding, focusing largely on its non-factive nature and the extent to which a certain kind of know-how is required for the “grasping” component of understanding. I will explore four central issues that feature in this chapter, concentrating on the role of know-how, the concept of endorsement, Elgin’s critique of the factivity constraint on understanding, and how we might use aspects of Elgin’s framework to inform related debates on the (...) norm of assertion.

According to Persson and Savulescu, the risks posed by a morally corrupt minority's potential to abuse cognitive enhancement make it such that we have an urgent imperative to first pursue moral enhancement of humankind – and, consequently, if we are a long way from safe, effective moral enhancement, then we have at least one good reason to consider opposing further cognitive enhancement. However, as Harris points out, such a proposal seems to support delaying life-saving cognitive progress. In this article, we (...) first show that Harris's worry can be expanded to show that Persson and Savulescu's proposal also threatens the development of moral enhancement – precisely what they suggest we have pro tanto reason to pursue. From there, we offer our own, alternative proposal – one on which cognitively enhanced researchers play a key role in the production of moral enhancement, and those in the general population who wish to be cognitively enhanced must first accept moral enhancement as an entry requirement. We engage with four substantive objections to our proposal and use these objections to refine and strengthen the details. (shrink)

This work addresses corruption in politics and the public services, arguing that corrupt public officials should be exposed, prosecuted and gaoled, just like their colleagues in the private sector. It covers ethical standards in the public service, both state and federal; the practice of government; the relationships between officials; their advisors and the public; the interplay between politics and personal behaviour, and offering explanations as to what can be done about corruption in public service through asking questions like; how does (...) corruption gain a foothold in public affairs?; how can public trust be rebuilt between bureaucrats, the politicians and the people who vote for them?; and how can we improve accoutability over the cover-ups?

In this paper, a concept of chance is introduced that is compatible with deterministic physical laws, yet does justice to our use of chance-talk in connection with typical games of chance. We take our cue from what Poincaré called "the method of arbitrary functions," and elaborate upon a suggestion made by Savage in connection with this. Comparison is made between this notion of chance, and David Lewis' conception.

The World Anti-Doping Code (2021) includes a substance on the prohibited list if it meets at least two of the following: (1) it has the potential to enhance or enhances sport performance; (2) it represents an actual or potential health risk to the athlete; (3) it violates the spirit of sport. This paper uses a case study to illustrate points of tension between this code and enhancements that are appropriate to ban; we argue that there are banned drugs (e.g., acetazolamide (...) and dexamethasone) the use of which we have good reason to not only permit but encourage for high-altitude sports. Drawing on lessons from this case study, we propose a reformulation of the Code that requires (1–3) be met but offers preferable ways of unpacking conditions (1) and (3) – and in a way that better preserves how the spirit of sport condition should be indexed to particular sports. Our formulation is inclusive enough to rule in drugs like acetazolamide and dexamethasone as permissible in high-altitude sports while at the same time ruling out problem cases – including many drugs already on the prohibited list. The result is an attempted alignment between the conditions specified and those drugs that should be banned. (shrink)

Should we regard Jennifer Lackey’s ‘Creationist Teacher’ as understanding evolution, even though she does not, given her religious convictions, believe its central claims? We think this question raises a range of important and unexplored questions about the relationship between understanding, factivity and belief. Our aim will be to diagnose this case in a principled way, and in doing so, to make some progress toward appreciating what objectual understanding—i.e., understanding a subject matter or body of information—demands of us. Here is the (...) plan. After some ground clearing in §1, §2 outlines and motivates a plausible working model—moderate factivity—for characterising the sense in which objectual understanding should be regarded as factive. §3 shows how the datum that we can understand false theories can, despite initial suggestions to the contrary, be assimilated straightforwardly within the moderate factivity model. §4 highlights how the inverse kind of case to that explored in §3—viz., a variant of Lackey’s creationist teacher case—poses special problems for moderate factivity. With reference to recent work on moral understanding by Hills, §5 proposes a solution to the problem, and §6 attempts to diagnose why it is that we might originally have been led to draw the wrong conclusion.

It is argued that understanding is the norm of political discourse, and it is shown why political assertions can be epistemically problematic within a liberal democracy even when asserted knowledgeably.

If some sort of dynamical collapse theory is correct, what might the world be like? Can a theory of that sort be a quantum state monist theory, or must such theories supplement the quantum state ontology with additional beables? In a previous work, I defended quantum state monism, with a distributional ontology along the lines advocated by Philip Pearle. In this chapter the account is extended to collapse theories in relativistic spacetimes.

Bioconservative bioethicists (e.g., Kass, 2002, Human Dignity and Bioethics, 297–331, 2008; Sandel, 2007; Fukuyama, 2003) offer various kinds of philosophical arguments against cognitive enhancement—i.e., the use of medicine and technology to make ourselves “better than well” as opposed to merely treating pathologies. Two notable such bioconservative arguments appeal to ideas about (1) the value of achievement, and (2) authenticity. It is shown here that even if these arguments from achievement and authenticity cut ice against specifically pharmacologically driven cognitive enhancement, they (...) do not extend over to an increasingly viable form of technological cognitive enhancement – namely, cognitive enhancement via augmented reality. An important result is that AR-driven cognitive enhancement aimed at boosting performance in certain cognitive tasks might offer an interesting kind of “sweet spot” for proponents of cognitive enhancement, allowing us to pursue many of the goals of enhancement advocates without running into some of the most prominent objections from bioconservative philosophers.

The Akaike Information Criterion can be a valuable tool of scientific inference. This statistic, or any other statistical method for that matter, cannot, however, be the whole of scientific methodology. In this paper some of the limitations of Akaikean statistical methods are discussed. It is argued that the full import of empirical evidence is realized only by adopting a richer ideal of empirical success than predictive accuracy, and that the ability of a theory to turn phenomena into accurate, agreeing measurements (...) of causally relevant parameters contributes to the evidential support of the theory. This is illustrated by Newton's argument from orbital phenomena to the inverse-square law of gravitation. (shrink)

The Reeh-Schlieder theorem asserts the vacuum and certain other states to be spacelike superentangled relative to local quantum fields. This motivates an inquiry into the physical status of various concepts of localization. It is argued that a covariant generalization of Newton-Wigner localization is a physically illuminating concept. When analyzed in terms of nonlocally covariant quantum fields, creating and annihilating quanta in Newton-Wigner localized states, the vacuum is seen to not possess the spacelike superentanglement that the Reeh-Schlieder theorem displays relative to (...) local fields, and to be locally empty as well as globally empty. Newton-Wigner localization is then shown to be physically interpretable in terms of a covariant generalization of the center of energy, the two localizations being identical if the system has no internal angular momentum. Finally, some of the counterintuitive features of Newton-Wigner localization are shown to have close analogues in classical special relativity. (shrink)

The hidden-variables model constructed by Karl Hess and Walter Philipp is claimed by its authors to exploit a "loophole" in Bell's theorem; according to Hess and Philipp, the parameters employed in their model extend beyond those considered by Bell. Furthermore, they claim that their model satisfies Einstein locality and is free of any "suspicion of spooky action at a distance." Both of these claims are false; the Hess-Philipp model achieves agreement with the quantum-mechanical predictions, not by circumventing Bell's theorem, but (...) via Parameter Dependence. (shrink)

Current regulations and guidelines identify specific subject populations as vulnerable. Regulations and guidelines generally stipulate protections with regard to the process of informed consent. Recent clinical trials suggest that satisfying the legal requirements for additional safeguards may not protect subjects to the extent we may desire. We present proposed guidelines for the protection of decisionally impaired subjects throughout the course of the trial.

This dissertation is an investigation into the degree to which the mathematics used in physical theories can be constructivized. The techniques of recursive function theory and classical logic are used to separate out the algorithmic content of mathematical theories rather than attempting to reformulate them in terms of "intuitionistic" logic. The guiding question is: are there experimentally testable predictions in physics which are not computable from the data? ;The nature of Church's thesis, that the class of effectively calculable functions on (...) the natural numbers is identical to the class of general recursive functions, is discussed. It is argued that this thesis is an example of an explication of the very notion of an effectively calculable function. This is contrary to a view of the thesis as a hypothesis about the limitations of the human mind. ;The extension to functions of a real variable of the notion of effective calculability is discussed, and it is argued that a function of a real variable must be continuous in order to be considered effectively calculable . The relation between continuity and computability is significant for the problem at hand. The results of a well-designed experiment do not depend critically upon the precise values of the relevant parameters. Accordingly, if the solution to a problem in mathematical physics depends discontinuously upon the data, it cannot be regarded as an experimentally testable prediction of the theory. The principle that the testable predictions of a physical theory cannot be singular is known as the principle of regularity. This principle is significant, because discontinuities generate non-computability, but they also disqualify a prediction from being experimentally testable. ;A mathematical framework is set up for discussing computability in physical theories. This framework is then applied to the case of quantum mechanics. It is found that, due to the use of unbounded operators in the theory, noncomputable objects appear, but predictions which satisfy the principle of regularity are nevertheless computable functions of the data.
