A number of ways of taxonomizing human learning have been proposed. We examine the evidence for one such proposal, namely, that there exist independent explicit and implicit learning systems. This combines two further distinctions, (1) between learning that takes place with versus without concurrent awareness, and (2) between learning that involves the encoding of instances (or fragments) versus the induction of abstract rules or hypotheses. Implicit learning is assumed to involve unconscious rule learning. We examine the evidence for implicit learning (...) derived from subliminal learning, conditioning, artificial grammar learning, instrumental learning, and reaction times in sequence learning. We conclude that unconscious learning has not been satisfactorily established in any of these areas. The assumption that learning in some of these tasks (e.g., artificial grammar learning) is predominantly based on rule abstraction is questionable. When subjects cannot report the rules that govern stimulus selection, this is often because their knowledge consists of instances or fragments of the training stimuli rather than rules. In contrast to the distinction between conscious and unconscious learning, the distinction between instance and rule learning is a sound and meaningful way of taxonomizing human learning. We discuss various computational models of these two forms of learning. (shrink)

In the original target article (Shanks & St. John 1994), one of our principal conclusions was that there is almost no evidence that learning can occur outside awareness. The continuing commentaries raise some interesting questions, especially about the definition of learning, but do not lead us to abandon our conclusion.

The ”dark night of the soul’ is a common motif in Christian spiritual writing; and the locus classicus for this motif is the work of John of the Cross, a Spanish Carmelite friar of the sixteenth century. My aim in this paper is to use John’s account of the ”night’ to consider how the themes of mystery, humility and religious practice may be subsumed, and related to one another, within a Christian conception of God and of human life (...) lived out in relation to God.

The prolific English poet John Lydgate has been known as the “monk of Bury” since the early fifteenth century. Both his popularity and perceptions of his literary merit have fluctuated wildly since his zenith as the famous laureate of Henry V, Henry VI and Duke Humphrey, but readers have been constant in their association of Lydgate with the Benedictine abbey from which the epithet derives. However, there has been remarkably little examination of the details of Lydgate's existence at Bury: (...) the critical emphasis has been on Lydgate's contact with Lancastrian society rather than on his quotidian life as a monk. “To trace in detail the connection between the Bury library and the characteristic configuration of Lydgate's thought and work, to see how his mind was formed and influenced by the books with which he was in such familiar contact” remains an unfulfilled desire. In particular, given the range of Lydgate's literary and intellectual allusions, it is surprising that there has been no full attempt to compare what we know of Bury's sizeable late medieval library, catalogued in the late fourteenth century by Henry Kirkstede, with Lydgate's poetic output. Likewise, few critics have attempted to trace connections between Lydgate's poetry and the intellectual and cultural atmosphere of a grand Benedictine abbey in the late medieval period. This article, a study of one manuscript from Bury that Lydgate certainly handled and that is typical of the type of book he would have encountered in great numbers in the monastic library, endeavours to reassert the importance to his poetry of the environment in which Lydgate spent most of his life.

In 1911, Drs John Freeman and Leonard Noon published an account of a novel treatment for hay fever. Their method of desensitisation consisted of injecting increasing doses of an extract of pollen subcutaneously until the hypersensitivity reaction was diminished or abolished. Over subsequent decades, desensitisation established itself as the cornerstone of clinical allergy in both England and the United States, at least until the advent of novel pharmaceutical agents in the 1950s and 1960s. Although British allergists such as Noon (...) and Freeman were aware of conceptual developments within European immunology and pathology (such as the identification of anaphylaxis by Richet and Portier or von Pirquet's coining of the term allergy), their approach to hay fever was driven by more immediate pragmatic, and indeed financial, considerations. Freeman's immersion in the problems of hay fever and asthma and his pioneering use of allergen desensitisation or immunotherapy were shaped by his adherence to the convictions and bacteriological practices of his principal at St Mary's Hospital, Almroth Wright, and by the drive to produce commercial vaccines which would help to subsidise the experimental and therapeutic work at St Mary's. The aim of this paper is to explore early twentieth-century approaches to hay fever and other allergic diseases by tracing the intellectual and institutional origins of clinical allergy in Britain.

My first article, back in 1989! Thanks, forever, Ralph McInerny. Here I take issue with John F.X. Knasas, a strong supporter of the existential Thomism of Etienne Gilson and Joseph Owens. Knasas's desire to sequester Thomas away from allowing the discipline of natural philosophy to arrive at a fully immaterial reality through its proper demonstrative methods seemed to me to be at odds with Thomas's text.

Of John Stuart Mill's major commitments, none was more passionately pursued than equality; it marks his writings throughout his life, and serves as a uniting force in his comments on many subjects, especially lawand education. This volume presents, in scholarly form for the first time, writings that reveal his goals and methods in diverse circumstances. They begin with his precocious essay on the law of libel and include his influential Subjection of Women, his major essays on slavery, his Inaugural (...) Address at St Andrews, and his contributionsin the struggle to being Governor Eyre of Jamaica to trial. A variety of shorter essays is also presented: such personal documents as his declaration just before amrriage renouncing all legal rights over his wife, and his and Harriett Taylor's companion pieces on marriage, newly edited from manuscript. Also included is Mill's evidence before parliamentary committees on education and the Contagious Diseases Acts. The appendices include ancillary texts and a bibliographic index listing all works and persons mentioned or quoted in the essays. An analytic index gives easy access to the full range of Mill's ideas in these important essays. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:276 THE WILL AS IMPRESSION Hume writes, in the Treatise: Let no one, therefore, put an invidious construction on my words, by saying simply, that I assert the necessity of human actions, and place them on the same footing with the operations of senseless matter. I do not ascribe to the will that unintelligible necessity, which is suppos'd to lie in matter. But I ascribe to matter, that intelligible (...) quality, call it necessity or not, which the most rigorous orthodoxy does or must allow to belong to the will. I^ change, therefore, nothing in the receiv'd systems, with regard to the will, but only with regard to material objects. It is surely false that Hume changed "nothing in the receiv'd systems, with regard to the will." In one such "receiv'd system," that of Thomas Aquinas, the concept of will or volition is presented as internally related to two further concepts: that of the "final cause" or goal of the action, and that of "practical intellect," a form of cognition which is productive of its object. Will is always the will to something, a goal to be reached or a product to be produced. Thus will and final cause are concepts which presuppose one another. The mark, however, of the fact that someone wills to do something, i.e., that s/he in fact has some goal, is precisely that that agent knows, non-inductively and without observation, what s/he is doing or will do. The basis of this knowledge is neither evidence nor proof, but rather what Aristotle called "the practical syllogism." We will ask below what it means to describe the relationships among will, final cause, and practical knowledge as 'internal.' 277 The question to be explored here is this: what in fact becomes of the 'receiv'd concept of will' when one contends, in the empiricist spirit common to both Locke and Hume, that all of our knowledge about matters of fact is based on observation and induction? The answer to this question will turn out to be that, in the absence of a notion of "practical knowledge," the concept of final cause becomes unintelligible (since the final cause is precisely the object of practical knowledge); and thus the notion of will must be reconstrued, for Hume as an impression. As an impression it is a brute given, one that is furthermore mute (or lacking in propositional content). Hume views volition as an event, that object of inner experience which is the (Humean) cause of our voluntary actions. In what follows I shall first of all sketch Thomas Aquinas' view of the will (section I), following this with a discussion of the important hybrid view in Locke's Essay, where older notions of volition are presented within an incompatible epistemological framework. In section III we look at Hume's sharp response to Locke, and in section IV at his own doctrine of the will as impression. In the final section I attempt to distinguish two strands of causality in Hume's philosophy of human action, drawing at the same time a moral for the contemporary dispute about reasons and causes. One of the most fully developed of the "receiv'd systems with regard to the will" was that of St. Thomas Aquinas, who combined Neo-Platonist, Patristic, and Aristotelian sources into an 2 impressive and influential synthesis. Thomas' 278 doctrine on the will is guided by a Grand Analogy, one inspired by the Creation story in Genesis. He writes, at the beginning of the second main part of his Summa : Man is made to God's image, and since this implies... that he is intelligent and free to judge and master of himself, so then, now that we have agreed [in part one of the Summa] that God is the exemplar cause of things and that they issue from his power through his will, we go on to look at this image, that is to say, at man as the source of actions which are his own and fall under his responsibility and control. The analogy is this: God, the Divine Craf tsperson, is to the Creation as human agents are to their... (shrink)

Clinical Ethics, Ahead of Print. This paper is a response to a recent BMJ Blog: ‘The duty to treat: where do the limits lie?’ Members of the Surrey Heartlands Integrated Care Service Clinical Ethics Group reflected on arguments in the Blog in relation to resuscitation during the COVID-19 pandemic.Clinicians have had to contend with ever-changing and conflicting guidance from the Resuscitation Council UK and Public Health England regarding personal protective equipment requirements in resuscitation situations. St John Ambulance had different (...) guidance for first responders.The situation regarding resuscitation led the CEG to consider ethical aspects of health care professionals’ responses to the need for resuscitation during COVID-19. Members agreed that professionals should, ideally, have the level of PPE required for an aerosol generating procedure. However, there was no consensus regarding professionals’ duty to care when this is not available. On the one hand, it was agreed that the casualty/patient’s interests regarding resuscitation should be prioritised due to professionals’ contract with the public and professional privilege. On the other hand, risk thresholds were considered relevant to individual decision-making and professionals’ duty to care. All agreed that decision-making should not be influenced by rewards or reprimands. It was agreed also that decisions to resuscitate should not be considered as moral heroism or supererogatory - regardless of PPE availability - but rather as ‘minimally decent’. We agreed that it may be acceptable for professionals, with good reasons, to opt out of resuscitation attempts and these should be reflected on and discussed before the event. (shrink)

I begin by recounting the market demands that created an opportunity for me to teach business ethics in the College of Business at St. Cloud State University. The AACSB and my educational institution focused amorphous social demands for better business practices into a specific demand for a philosophy Ph.D. to teach business ethics. I felt frustrated teaching business ethics because of my inexperience and the eclectic nature of the field. I, and many others, searched for something to unify the many (...) topics of the field. This search was one of the factors that led to BEQ’s appearance in 1991. The first issue marked a milestone in the continuing search fortheory and the legitimization of the field. It focused previous discussions and was remarkably prescient. While it is unlikely that we will reach a consensus about how to understand the field, if consensus ever comes close to occurring, I argue that it will not coalesce over stakeholder theory. I examine two theories that could be used as a grand unified theory (GUT) of business ethics: Integrated Social Contracts Theory and my own institutional theory that expands on the work of Douglass North’s view of economic institutions. I usethe discussion of these GUTs to develop criteria of what a successful GUT might look like. Based on these criteria, I argue that theinstitutional theory has a better chance of succeeding, but recognize that business ethics GUTs are primarily heuristic; many different types of theories can be helpful. Lastly, I discuss whether it is pretentious and overbearing to argue for a GUT. I argue that it need not be. (shrink)

The paper develops a preliminary framework for confronting poverty within the Eastern Orthodox Christian tradition. In the first section, I draw on St. Gregory of Nazianzus’s Oration 14 to discuss what is called the stigma of poverty. Although stigmatization is not essentially linked to everyday economic poverty, poor people as such are often subjected to stigmatization. For example, disaffiliation grounded in social rejection was often a distinguishing mark between pôtchos and penês. Moreover, stigmatization in itself constitutes its own form (...) of poverty since those who are stigmatized are imputed to be fundamentally impoverished or defective as person. In the second section, I focus on the writings of St. John Chrysostom and argue that the central problem for Chrysostom is not poverty but wealth, or more properly the ways in which we acquire and use wealth and the ends to which it is put. Put simply, for Chrysostom, a critical, engaged and spiritual response to poverty presupposes a critical and spiritual response to wealth. (shrink)

Over the past 40 years, scholars and practitioners of public relations have often cast public relations workers in the role of the public relations-person-as-corporate-conscience. This work, however, maintains that this construct is so problematic that invoking it is of negligible use in addressing ethical issues that emerge during a crisis. In fact, a complex crisis, such as the Jahi McMath “brain death” case at Children’s Hospital Oakland, demonstrates the need to abandon the PRPaCC construct to better engage affected stakeholders, including (...) “outsiders” to the organization, who often determine whether an organization is facing a crisis. Through an examination of both the concept of the PRPaCC and the McMath crisis, this work makes the case for moving beyond the PRPaCC construct in favor of a more modest role for the public relations person: facilitating widespread ethical deliberation and discussion throughout an organization, potentially helping the organization alleviate concerns that contribute to crises.

Known to produce out-of-body states and profound changes in sensory perception, mood, and thought, DMT is a potent short-lasting tryptamine that has experienced growing appeal in the last decade, independent from ayahuasca, the Amazonian visionary brew in which it is an integral ingredient. Investigating user reports available online as well as a variety of other sources consulted in extended cultural research, this article focuses on the “breakthrough” event commonly associated with the DMT trance. The DMT breakthrough event coincides with significant (...) revelatory outcomes associated with perceived contact with “entities” and the transmission of information often in the form of visual language. Examination of the breakthrough event offers insight on the liminal phenomenology of DMT and other tryptamines, a liminality that is given primary expression in reported travels in “hyperspace.” The article examines user reports of DMT “hyperspace” observing a transitional process that, unlike conventional passage rites, is private, individualized, internal, and “ritual like.” As an exploratory discussion of an under-researched phenomenon, the article enters this virtual terrain through a discussion of the gnostic, therapeutic, and recreational modalities of DMT use, before exploring ritual-like modes of transmission and concluding with comments on the ontological significance of the DMT trance.

In A Theory of Justice, John Rawls devised the method of reflective equilibrium in an attempt to broker consensus between ethical approaches emphasising individual moral judgements, and those emphasising moral principles, expanding this method in the later paper; “The Independence of Moral Theory”, to produce wide reflective equilibrium. In a number of essays compiled in Justice and Justification, Norman Daniels articulated a more comprehensive version of Rawls's methodology in response to something of a similar struggle within contemporary bioethics, between (...) those bioethical approaches emphasising individual moral judgements, those emphasising bioethical principles and those emphasising bioethical theory; the casuists, the principlists and the descriptivists respectively. In addition to the level of considered moral judgements and that of moral principles that comprise Rawls's reflective equilibrium, Daniels's model proposes a third level of interconnecting background theories in order to incorporate the three dominant strands of contemporary bioethics, to broker consensus between those whose considered moral judgements are in conflict, and to guard against the endpoint of the reflective equilibrium being overly determined by these judgements. However, it is unclear whether his method aids the objectives he set, or whether it in fact hinders them. (shrink)

Australian legislation at both state and federal levels has been passed in the last two years enabling the creation and use of cloned embryos up until their fourteenth day of development. Yet for this fourteen-day threshold to carry moral weight it must be shown that an embryo may be plausibly attributed some kind of moral standing after this point that it cannot be accorded before it Moral standing may be conferred using Steven Buckle’s account of potential to become (after one (...) problem with his account is dealt with) but such standing has often been withheld from the embryo prior to the fourteenth day due to the possibility of monozygotic twinning and the violation of numerical continuity this represents. This article discusses the influential argument regarding monozygotic twinning articulated by Peter Singer and Helga Kuhse, and finds it insufficient to negate either the ‘identity thesis’ they describe or Buckle’s account of potential to become.

This review focuses on Pekka Hämäläinen’s characterization and analysis of the Comanche empire as a spatial category in The Comanche Empire and discusses how this work relates to broader discussions about space and power in borderlands and imperial histories. Although empires have long been central actors in borderlands histories, “empire” has not necessarily been a category of spatial organization and analysis and certainly not one used to describe spaces controlled by Native peoples. By contrast, while Hämäläinen emphasizes the imperial characteristics (...) of the economic, political, and cultural dimensions of Comanche history , he also uses “empire” to characterize Comanche dominance spatially. Hämäläinen helps us to rethink the spatial dynamics that both shaped and were produced by the encounters between Comanches and Spaniards, French, Mexicans, Americans, and other Native peoples in the Great Plains during the eighteenth and nineteenth centuries. By analyzing how Comanches came to control vast stretches of the southern plains, The Comanche Empire challenges our assumptions about how Native polities and imperial powers thought about territorial claims and how they employed more nuanced spatial strategies to assert their authority, extend their cultural influence, and control trade and resources.

What do we mean when we say we want to put children at the centre of policy? What are the moral justifications for this approach? Has it become harder for us to understand this concept, when in practice paid work has been at the centre? In part confusion arises because the unpaid work of caring for children is invisible until it is marketized. In turn, the underlying problem is that we have forgotten our traditions of egalitarianism and adopted a powerful (...) mindset that is proving to be paralyzing. Exploring New Zealand family policies such as paid parental leave, early childhood education, child tax credits suggests that there is much room for improvement if the needs of children are to come first. But first and foremost we must have a very different, child-centric, colour-blind, non-judgmental change of heart. (shrink)

Contemporary virtue epistemology (hereafter ‘VE’) is a diverse collection of approaches to epistemology. At least two central tendencies are discernible among the approaches. First, they view epistemology as a normative discipline. Second, they view intellectual agents and communities as the primary focus of epistemic evaluation, with a focus on the intellectual virtues and vices embodied in and expressed by these agents and communities. -/- This entry introduces many of the most important results of the contemporary VE research program. These include (...) novel attempts to resolve longstanding disputes, solve perennial problems, grapple with novel challenges, and expand epistemology’s horizons. In the process, it reveals the diversity within VE. Beyond sharing the two unifying commitments mentioned above, its practitioners diverge over the nature of intellectual virtues, which questions to ask, and which methods to use. -/- It will be helpful to note some terminology before proceeding. First, we use ‘cognitive’, ‘epistemic’ and ‘intellectual’ synonymously. Second, we often use ‘normative’ broadly to include not only norms and rules, but also duties and values. Finally, ‘practitioners’ names contemporary virtue epistemologists. (shrink)

Beliefs are concrete particulars containing ideas of properties and notions of things, which also are concrete. The claim made in a belief report is that the agent has a belief (i) whose content is a specific singular proposition, and (ii) which involves certain of the agent's notions and ideas in a certain way. No words in the report stand for the notions and ideas, so they are unarticulated constituents of the report's content (like the relevant place in "it's raining"). The (...) belief puzzles (Hesperus, Cicero, Pierre) involve reports about two different notions. So the analysis gets the puzzling truth values right. (shrink)

Why would a successful physician who has undergone seven years of rigorous medical training take the trouble to seek out and learn to practice alternative methods of healing such as homeopathy and Chinese medicine? From Doctor to Healer answers this question as it traces the transformational journeys of physicians who move across the philosophical spectrum of American medicine from doctor to healer. Robbie Davis-Floyd and Gloria St. John conducted extensive interviews to discover how and why physicians make the move (...) to alternative medicine, what sparks this shift, and what beliefs they abandon or embrace in the process. After outlining the basic models of American health care-the technocratic, humanistic, and holistic-the authors follow the thoughts and experiences of forty physicians as they expand their horizons in order to offer effective patient care. The book focuses on the radical shift from one end of the spectrum to the other-from the technocratic approach to holism-made by most of the interviewees. Because many American physicians find such a drastic change too threatening, the authors also address the less radical transition to humanism-a movement toward compassionate care arising from within the medical system.

This is a delightful and scholarly work on a little known area in the history of American philosophy. Its appeal will be to Platonists and particularly to those philosophers who have a more intimate acquaintance with the intellectual climate of the American Midwest. Writing as an American philosopher and midwesterner the author states that ‘if we are to understand our heritage... we must seek knowledge of less obvious forces and personalities which have left their unheralded but indelible mark upon (...) our past’. With an abundance of evidence based upon considerable research of the most varied kind, he shows that the real productivity in philosophy in America in the latter part of the nineteenth century was to be found in the Midwest, especially in the contributions of such ‘less obvious personalities’ as William Torrey Harris, Dr Hiram K Jones and Thomas Johnson. After a brief introductory study of Harris and the St Louis movement in philosophy—a movement largely Hegelian in its origins and influence—the author confines the greater part of his account to the work of Dr Hiram K Jones, the founder of Platonism in the Midwest, and to Thomas M Johnson the scholar and bibliophile of Platonism.

All known structural extensions of the substructural logic $\textbf{FL}_{\textbf{e}}$, the Full Lambek calculus with exchange/commutativity (corresponding to subvarieties of commutative residuated lattices axiomatized by $\{\vee, \cdot, 1\}$ -equations), have decidable theoremhood; in particular all the ones defined by knotted axioms enjoy strong decidability properties (such as the finite embeddability property). We provide infinitely many such extensions that have undecidable theoremhood, by encoding machines with undecidable halting problem. An even bigger class of extensions is shown to have undecidable deducibility problem (the (...) corresponding varieties of residuated lattices have undecidable word problem); actually with very few exceptions, such as the knotted axioms and the other prespinal axioms, we prove that undecidability is ubiquitous. Known undecidability results for non-commutative extensions use an encoding that fails in the presence of commutativity, so and-branching counter machines are employed. Even these machines provide encodings that fail to capture proper extensions of commutativity, therefore we introduce a new variant that works on an exponential scale. The correctness of the encoding is established by employing the theory of residuated frames. (shrink)

Clausewitz's ?remarkable trinity? has long been a touchstone for discourse on the military's strategic position relative to other essential elements of Western society. Similarly, the just war tradition has long been a touchstone for moral discourse on war. Although these touchstones represent two intellectual traditions which may appear to have little or nothing in common, the 21st-century strategist or policymaker must take into account the imperatives of both traditions. This is so because, in the Information Age, public reactions to perceived (...) moral shortcomings associated with the decision to go to war, or with perceived moral lapses on the battlefield, can significantly disrupt the balance which the ?remarkable trinity? requires. Accordingly, this study takes as its task to propose a model which accommodates the concerns of both traditions. It first examines both formulations of Clausewitz's ?remarkable trinity? and then proposes a revised model of the ?remarkable trinity? which accommodates just war concerns. It concludes with some reflections on contemporary applications of the model, especially as it relates to the instruments of national power. (shrink)
