Is the no-minimum claim true? I have argued that it is not. Andrew Cullison contends that my argument fails, since human sentience is variable; while Michael Schrynemakers has contended that the failure is my neglect of vagueness. Both, I argue, are wrong.

The aim of the famous Born and Jordan 1925 paper was to put Heisenberg’s matrix mechanics on a firm mathematical basis. Born and Jordan showed that if one wants to ensure energy conservation in Heisenberg’s theory it is necessary and sufficient to quantize observables following a certain ordering rule. One apparently unnoticed consequence of this fact is that Schrödinger’s wave mechanics cannot be equivalent to Heisenberg’s more physically motivated matrix mechanics unless its observables are quantized using this rule, (...) and not the more symmetric prescription proposed by Weyl in 1926, which has become the standard procedure in quantum mechanics. This observation confirms the superiority of Born–Jordan quantization, as already suggested by Kauffmann. We also show how to explicitly determine the Born–Jordan quantization of arbitrary classical variables, and discuss the conceptual advantages in using this quantization scheme. We finally suggest that it might be possible to determine the correct quantization scheme by using the results of weak measurement experiments. (shrink)

In this paper, we show within ${\mathsf{RCA}_0}$ that both the Jordan curve theorem and the Schönflies theorem are equivalent to weak König’s lemma. Within ${\mathsf {WKL}_0}$ , we prove the Jordan curve theorem using an argument of non-standard analysis based on the fact that every countable non-standard model of ${\mathsf {WKL}_0}$ has a proper initial part that is isomorphic to itself (Tanaka in Math Logic Q 43:396–400, 1997).

Gregory the Great depicts himself as a contemplative who, as bishop of Rome, was compelled to become an administrator and pastor. His theological response to this existential tension illuminates the vexed questions of his relationships to predecessors and of his legacy. Gregory develops Augustine’s thought in such a way as to satisfy John Cassian’s position that contemplative vision is grounded in the soul’s likeness to the unity of Father and Son. For Augustine, “mercy” lovingly lifts the neighbor toward life in (...) God. Imitating God’s own love for humankind, this mercy likens the Christian to God’s essential goodness and, by this likeness, prepares him or her for the vision of God, which Augustine expects not now but only in the next life. For Augustine, the exercise of mercy can—when useful—involve a shared affection or understanding. Gregory makes this shared affection essential to the neighborly love that he calls “compassion.” In this affective fellowship, Gregory finds a human translation of the passionless unity of Father and Son—so that, for Gregory, compassion becomes the immediate basis for and consequence of seeing God—even in this life. Compassion does not degrade; rather, it retrenches the perfection of contemplation. Reconciling compassionate activity and contemplative vision, this creative renegotiation of Augustine and Cassian both answered Gregory’s own aspirations and gave to the tumultuous post-Imperial West a needed account of worldly affairs as spiritual affairs.

Strawson (1994) and Peacocke (1992) introduced thought experiments that show that it seems intuitive that there is, in some way, an experiential character to mental events of understanding. Some (e.g., Siewert 1998, 2011; Pitt 2004) try to explain these intuitions by saying that just as we have, say, headache experiences and visual experiences of blueness, so too we have experiences of understanding. Others (e.g., Prinz 2006, 2011; Tye 1996) propose that these intuitions can be explained without positing experiences of understanding. (...) Call this the debate between Realism and Anti-Realism about experiences of understanding. This paper aims to advance that debate in two ways. In the first half, I develop more precise characterizations of what Realists and Anti-Realists propose. In the second half, I distinguish the four most plausible versions of Anti-Realism and argue that Realism better explains the target intuition than any of them does. (shrink)

Access to abortion care has been hugely affected by the COVID-19 pandemic. This has prompted several governments to permit the use of telemedicine for fully remote care pathways, thereby ensuring pregnant people are still able to access services. One such government is that of England, where these new care pathways have been publicly scrutinised. Those opposed to telemedical early medical abortion care have raised myriad concerns, though they largely centre on matters of patient safeguarding. It is argued that healthcare professionals (...) cannot adequately carry out their safeguarding duties if the patient is not in the room with them. These concerns lack empirical support. Emerging evidence suggests that safeguarding processes may, in fact, be more effective within telemedical abortion care pathways. In this article, we address two specific safeguarding concerns: (1) that a remote consultation prevents a healthcare professional from identifying instances of abuse, and (2) that healthcare professionals cannot reliably confirm the absence of coercion during a remote consultation. We demonstrate that such concerns are misplaced, and that safeguarding may actually be improved in telemedical care pathways as victims of abuse may find it easier to engage with services. It is inevitable that some individuals will fall through the net, but this is unavoidable even with in-person care and thus does not constitute a strong critique of the use of telemedicine in abortion care. These safeguarding concerns set aside, then, we argue that the current approval that enables telemedical early medical abortion should be afforded permanence. (shrink)

To systematically answer the generalized Kretschmann objection, I propose a mean to make operational a criterion widely recognized as allowing one to decide whether the gauge symmetry of a theory is artificial or substantial. My proposition is based on the dressing field method of gauge symmetry reduction, a new simple tool from mathematical physics. This general scheme allows one in particular to straightforwardly argue that the notion of spontaneous symmetry breaking is superfluous to the empirical success of the electroweak theory. (...) Important questions regarding the context of justification of the theory then arise. (shrink)

Jordan made substantial market access commitments as part of its WTO membership negotiations. Jordan has low average tariffs with single or two digits rate and ad valorem-only duties with some exceptions where specific duties apply. Customs standards in Jordan were streamlined in accordance with WTO rules.

The purpose of this article is to examine and analyse Jordan’s current imports and tariffs regime. (shrink)

This book presents a comprehensive mathematical study of the operators behind the Born-Jordan quantization scheme. The Schrödinger and Heisenberg pictures of quantum mechanics are equivalent only if the Born-Jordan scheme is used. Thus, Born-Jordan quantization provides the only physically consistent quantization scheme, as opposed to the Weyl quantization commonly used by physicists. In this book we develop Born-Jordan quantization from an operator-theoretical point of view, and analyze in depth the conceptual differences between the two schemes. We (...) discuss various physically motivated approaches, in particular the Feynman-integral point of view. One important and intriguing feature of Born-Jordan quantization is that it is not one-to-one: there are infinitely many classical observables whose quantization is zero. (shrink)

Jordan acceded to the WTO in 1999. In its accession Jordan agreed, for example, to reduce tariffs on imported products and open its services market; it also modified its intellectual property regime. Jordan enjoyed special and differential treatment in few areas and was not able to designate olive oil as a good eligible for special safeguards. The WTO agreements required fundamental changes in the domestic laws and regulations of Jordan. The article concludes by arguing that (...) class='Hi'>Jordan’s accession to the WTO was a lengthy and costly process. Jordan agreed to an arduous package of legal and economic reforms. Given that Jordan agreed to greater commitments compared to the obligations of the original WTO members, the multilateral trading system witnessed an accession saga. (shrink)

The popularity of Jacques Rancière in recent work in educational philosophy has rejuvenated discussion of the merits and weaknesses of Socratic education, both in Plato's dialogues and in invocations of Socrates in contemporary educational practice. In this essay Jordan Fullam explores the implications of this trend through comparing Rancière's educational thought to an analysis of the relationship between dialectic and stultification in Plato's Republic. This task clarifies what is useful in the recent wave of scholarship that brings Rancière's work (...) to bear upon Socratic education, and what we might redeem in the practice of teaching that Plato assigns to the character of Socrates in the Republic. Fullam also draws on the educational literature on Socratic education to provide further context to explore the usefulness of both Rancière and Socrates for contemporary teaching. (shrink)

In the debate surrounding the morality and legality of the practices of physician-assisted death and euthanasia, a common logical argument regularly employed against these practices is the “slippery slope argument.” One formulation of this argument claims that acceptance of physician-assisted death will eventually lead down a “slippery slope” into acceptance of active euthanasia, including its voluntary, non-voluntary, and/or involuntary forms, through psychological and social processes that warp a society’s values and moral perspective of a practice over an extended period of (...) time. This formulation is known as the psychological slippery slope argument. This paper analyzes the psychological slippery slope argument as it is applied to the practice of physician-assisted death, and utilizing recent empirical evidence from various nations around the world that practice physician-assisted death and/or euthanasia, the paper argues that employing the psychological slippery slope argument against physician-assisted death is logically fallacious, this kind of slippery slope is unfounded in practice, and thus the psychological slippery slope argument is insufficient on its own to justify continued legal prohibition of physician-assisted death.

Readers of fiction tend to have better abilities of empathy and theory of mind. We present a study designed to replicate this finding, rule out one possible explanation, and extend the assessment of social outcomes. In order to rule out the role of personality, we first identified Openness as the most consistent correlate. This trait was then statistically controlled for, along with two other important individual differences: the tendency to be drawn into stories and gender. Even after accounting for these (...) variables, fiction exposure still predicted performance on an empathy task. Extending these results, we also found that exposure to fiction was positively correlated with social support. Exposure to nonfiction, in contrast, was associated with loneliness, and negatively related to social support. (shrink)

This article examines the nature of affective states across biological taxa. It argues that affect constitutes a primary form of consciousness. Creatures capable of affect are sentient of their bodily states and can behave in ways intended to maintain or restore them to a homeostatic range. After reviewing and critiquing neurobiological and philosophical theories of the evolution of consciousness, this article argues that some possible creatures are limited to self-directed affective states, even if those creatures are capable of exteroception. Such (...) creatures enjoy solipsistic sentience: awareness of their own selves and bodily demands, but unawareness of their exogenous environments. (shrink)

Agent-regret seems to give rise to a philosophical puzzle. If we grant that we are not morally responsible for consequences outside our control, then agent-regret—which involves self-reproach and a desire to make amends for consequences outside one’s control—appears rationally indefensible. But despite its apparent indefensibility, agent-regret still seems like a reasonable response to bad moral luck. I argue here that the puzzle can be resolved if we appreciate the role that agent-regret plays in a larger social practice that helps us (...) deal with bad moral luck. That agent-regret is a component in a social practice limits the questions that we can reasonably ask about it. While we can ask whether an experience of agent-regret is rational given the norms of this practice, we cannot ask the question that motivates the puzzle of agent-regret, viz. whether agent-regret is rationally defensible according to the Standard View.

Review of Ancient Concepts of Philosophy by William Jordan.

Roy Sorensen introduced the concept of an epistemic blindspot in the 1980s. A proposition is an epistemic blindspot for some individual at some time if and only if that proposition is consistent but unknowable by that individual at that time. In the first half of this paper, I extend Sorensen work on blindspots by arguing that there exist blindspots that essentially involve hopes. In the second half, I show how such blindspots can contribute to and impair different pursuits of self-understanding. (...) My arguments throughout this paper draw on Luc Bovens’s account of hope.

The celebrated Dreimännerarbeit by Born, Heisenberg and Jordan contains a matrix-mechanical derivation by Jordan of Planck’s formula for blackbody fluctuations. Jordan appears to have considered this to be one of his finest contributions to quantum theory, but the status of his derivation is puzzling. In our Dreimenschenarbeit, we show how to understand what Jordan was doing in the double context of a Boltzmannian approach to statistical mechanics and of the early ‘statistical interpretation’ of matrix mechanics.

Chemical kinds are generally treated as having timelessly fixed identities. Biological kinds are generally treated as evolved and/or evolving entities. So what kind of kind is a biochemical kind?

Moral extremists argue for a demanding duty of poverty relief by leveraging powerful intuitions about our duties to rescue those close at hand. I clear the way for a less demanding duty by arguing that this argumentative strategy commits the extremist to a conception of our duty in the face of global poverty that is deeply at odds with our convictions about how we may discharge that duty. These convictions reveal that global poverty and easy rescue cases give rise to (...) duties of different kinds: whereas duties of rescue are ultimately explicable by appeal to moral claims to assistance, duties of poverty relief are not. The extremist’s most compelling argumentative strategy is therefore not viable—he may not straightforwardly appeal to facts about the demandingness of duties of rescue in arguing for demanding duties of poverty relief.

In baseball, plate umpires are asked to make difficult perceptual judgments on a consistent basis.

A wide array of syntactic phenomena can be categorized as being either direction-sensitive (e.g. coordination) or direction-insensitive (quantification and medial extraction). In the realm of categorial grammar, many frameworks are engineered to handle one class of phenomena at the expense of the other. In particular, Lambek-inspired frameworks handle direction-sensitivity elegantly but struggle with cases of direction-insensitivity, whereas in linear grammars, the situation is just the opposite. One reasonably successful attempt to unify the insights of both types of grammar and allow (...) for the analysis of direction-sensitive as well as direction-insensitive phenomena is hybrid type-logical categorial grammar (HTLCG), which augments the set of syntactic categories of an ordinary linear grammar with the directional slashes of a Lambek grammar. In this paper, the complementary nature of Lambek and linear grammars, with respect to direction-sensitive and direction-insensitive phenomena, is expounded on, as is the nature of how HTLCG attempts to reconcile the two systems. The paper further discusses an alternative to HTLCG—a linear grammar which adds Lambek-like capabilities by augmenting the string-combining (phenogrammatic) mechanism instead of the definition of syntactic categories (the tectogrammar). In particular, LCGϕ\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\hbox {LCG}_\phi $$\end{document} (linear categorial grammar with phenominators) adds a form of subtyping based on phenominators—a class of linear functions which specify various modes of (phenogrammatic) combination. Most importantly, an algorithm is provided for embedding HTLCG into LCGϕ\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\hbox {LCG}_\phi $$\end{document}, thereby demonstrating that LCGϕ\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\hbox {LCG}_\phi $$\end{document} can handle direction-(in)sensitivity at least as well as HTLCG.

The COVID-19 pandemic is putting the NHS under unprecedented pressure, requiring clinicians to make uncomfortable decisions they would not ordinarily face. These decisions revolve primarily around intensive care and whether a patient should undergo invasive ventilation. Certain vulnerable populations have featured in the media as falling victim to an increasingly utilitarian response to the pandemic—primarily those of advanced years or with serious existing health conditions. Another vulnerable population potentially at risk is those who lack the capacity to make their own (...) care decisions. Owing to the pandemic, there are increased practical and normative challenges to following the requirements of the Mental Capacity Act 2005. Both capacity assessments and best interests decisions may prove more difficult in the current situation. This may create a more paternalistic situation in decisions about the care of the cognitively impaired which is at risk of taking on a utilitarian focus. We look to these issues and consider whether there is a risk of patients who lack capacity to make their own care decisions being short-changed. (shrink)

This Element examines Kant's innovative account of labour in his political philosophy and develops an intersectional analysis of Kant. By demonstrating that Kant's analysis of slavery, citizenship, and sex developed in inter-linked ways over several decades, culminating in his development of a 'trichotomy' of Right, the author shows that Kant's normative account of independence is configured through his theory of labour, and is continuous with his anthropological accounts of race and gender, providing a systemic justification for the dependency of women (...) and non-whites embedded in his philosophy of right. By examining Kant's arguments about slavery as intertwined with his account of domestic labour, the author argues that his ultimate rejection of slavery may owe more to his changing conceptualization of labour than to his theory of race, and that his final arguments against slavery rehearse strategies for embedding intersectional patterns of domestic dependence in his account of the rightful state.

Rules are meant to apply equally to all within their jurisdiction. However, some rules are frequently broken without consequence for most. These rules are only occasionally enforced, often at the discretion of a third-party observer. We propose that these rules—whose violations are frequent, and enforcement is rare—constitute a unique subclass of explicitly codified rules, which we call ‘phantom rules’ (e.g., proscribing jaywalking). Their apparent punishability is ambiguous and particularly susceptible to third-party motives. Across six experiments, (N = 1440) we validated (...) the existence of phantom rules and found evidence for their motivated enforcement. First, people played a modified Dictator Game with a novel frequently broken and rarely enforced rule (i.e., a phantom rule). People enforced this rule more often when the “dictator” was selfish (vs. fair) even though the rule only proscribed fractional offers (not selfishness). Then we turned to third person judgments of the U.S. legal system. We found these violations are recognizable to participants as both illegal and commonplace (Experiment 2), differentiable from violations of prototypical laws (Experiments 3) and enforced in a motivated way (Experiments 4a and 4b). Phantom rule violations (but not prototypical legal violations) are seen as more justifiably punished when the rule violator has also violated a social norm (vs. rule violation alone)—unless the motivation to punish has been satiated (Experiment 5). Phantom rules are frequently broken, codified rules. Consequently, their apparent punishability is ambiguous, and their enforcement is particularly susceptible to third party motives. (shrink)

The ‘black box problem’ is a long-standing talking point in debates about artificial intelligence. This is a significant point of tension between ethicists, programmers, clinicians and anyone else working on developing AI for healthcare applications. However, the precise definition of these systems are often left undefined, vague, unclear or are assumed to be standardised within AI circles. This leads to situations where individuals working on AI talk over each other and has been invoked in numerous debates between opaque and explainable (...) systems. This paper proposes a coherent and clear definition for the black box problem to assist in future discussions about AI in healthcare. This is accomplished by synthesising various definitions in the literature and examining several criteria that can be extrapolated from these definitions. There are no data in this work. (shrink)

In “Rethinking Race and Gender in Kant: Toward a Non-Ideal, Intersectional Kant,” Jordan Pascoe argues that Kant’s moral philosophy is productively read through the “non-ideal” lens of the sociopolitical concerns he faced and espoused.

She defends a non-ideal, modified methodological approach in which Kant’s problematic conception of race and gender are opportunities for expanding our reflection on Kant’s moral philosophy as a (...) whole.

In lieu of an abstract, here is a brief excerpt of the content:1. The impetus of Herbert Grundmann's work on researching the religious lives of women in the thirteenth century has led to a reinterpretation of many aspects of this complex subject. Even today, some points remain unclear. At times it seems as if we are confronted with a play in which the actors – the sisters, friars and the papal curia – move in a manner which is difficult to (...) decipher and could even be described as contradictory.In particular, Herbert Grundmann carried out a study on the development of female forms of monastic life which were linked with both the Franciscan and Dominican Friars; however, he neglected to give sufficient attention to the role of the papal curia in both Orders. The action of the papacy was considered merely an answer to demands made by nuns or friars – without grasping the fact that such decisions were due to a complex papal design in the reorganization of regular life.The history of the development of regular communities of religious women has a clear and systematic development. The women originally known as the pauperes dominae inclusae were not institutionally linked to the Order of Friars Minor until 1227, indicating the emergence of Apostolic guidelines to establish and build a new form of monastic life for women which was directly subject to papal authority. Until now, this aspect of religious foundations has not been the subject of scholarly attention, which has instead focused on the initiatives of the "founders" and risked taking the actual work out of context.The present article outlines the steps in the gradual legalization of the "Dominican" Sisters. Its findings are largely based on Jordan of Saxony's correspondence, which has not been given adequate scholarly consideration. Jordan was a Parisian master who entered the Order in 1220. He was subsequently elected Provincial Superior of Lombardy and in the following year until his death in 1237 was General Master of the Order. He also played a significant role in the foundation of the monastery of St. Agnese in Bologna.2. The complexity of the correspondence poses various problems. Not only because its very composition is based on continual discovery but also because of an almost total absence of historical information, which makes certain aspects difficult to interpret. Despite this, there is great interest in the reconstruction of significant moments in the constitutional history of the Order of Friars Preachers – a subject which has been enriched by the studies of Gert Melville as well as those of Sonderforschungsbereich himself.Jordan of Saxony's correspondence is composed of thirty-seven letters addressed to Diana of Andalo, who had professed religious vows before Dominic, and had played a leading role in creating the convent of St. Agnese in Bologna . Five of Jordan's letters were sent to Diana's convent and a further eight were sent to the general community.Beginning with the valuable observations of Angelo Walz, the most studied aspect of the correspondence has been feminine religious life with a particular focus on the spiritual themes which were elaborated on by Jordan. This is evident simply by referring to the observations of Raoul Manselli and Andrea Tilatti. The survival of Jordan's letters is due to the need to prove both their origins and their institutional link to the Order of Preachers. Since the 1430s, the nuns understood that by convincing both the Order and the Roman Curia of this, they might avoid the danger of losing the continued cura of the friars.Using this collection as a starting point, I intend to consider the institutional developments of the Bolognese Monastery, as well as female monasticism linked to the Order of Preachers.3. The Vita beatae Dianae was composed shortly after the middle of the thirteenth century. Despite its title, it primarily.. (shrink)

This article addresses a classical question: Can a machine use language meaningfully and if so, how can this be achieved? The first part of the paper is mainly philosophical. Since meaning implies intentionality on the part of the language user, artificial systems which obviously lack intentionality will be `meaningless'. There is, however, no good reason to assume that intentionality is an exclusively biological property and thus a robot with bodily structures, interaction patterns and development similar to those of human beings (...) would constitute a system possibly capable of meaning – a conjecture supported through a Wittgenstein-inspired thought experiment. The second part of the paper focuses on the empirical and constructive questions. Departing from the principle of epigenesis stating that during every state of development new structure arises on the basis of existing structure plus various sorts of interaction, a model of human cognitive and linguistic development is proposed according to which physical, social and linguistic interactions between the individual and the environment have their respective peaks in three consecutive stages of development: episodic, mimetic and symbolic. The transitions between these stages are qualitative, and bear a similarity to the stages in phylogenesis proposed by Donald and Deacon. Following the principle of epigenetic development, robotogenesis could possibly recapitulate ontogenesis, leading to the emergence of intentionality, consciousness and meaning. (shrink)
