In this paper we explore challenges facing leadership in a culture of “all consuming images” from a perspective which claims that images have a moral or normative dimension. The cumulative effect of contemporary image saturation is increased resistance to the normative power of an image. We also suggest that in a culturally diverse global economy, it is necessary to expand the moral aspects of good business leadership beyond providing a basis for productive, coherent group identity within a firm at the (...) expense of seeing outsiders as “others.” We also explore what imagining leadership in business might be like in a world in which visual images shape our understandings of individual and group identity. While our focus is on leadership in business, we also use examples from the political arena. We also suggest that imagining business leadership in the ways we propose may be helpful to women, providing them with an image of business leadership more closely reflective of their experience of corporate culture, its limits, and possibilities.

Hume, in "An Enquiry Concerning Human Understanding", holds (1) that all causal reasoning is based on experience and (2) that causal reasoning is based on nothing but experience. (1) does not imply (2), and Hume's good reasons for (1) are not good reasons for (2). This essay accepts (1) and argues against (2). A priori reasoning plays a role in causal inference. Familiar examples from Hume and from classroom examples of sudden disappearances and radical changes do not show otherwise. A (...) priori causal reasoning is closely related to understanding causal mechanisms. One uncovers the intelligibility of a causal process by understanding its mechanism. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Provoking a ConversationDavid H. PorterLee T. Pearcy's The Grammar of Our Civility: Classical Education in America (Baylor University Press, Waco, Tex. 2005) is a book every classicist should read. Pearcy's focus is on the state of classics in our country today: where we are, how we got there, where we need to go. His book is wide-ranging, tightly argued, and carefully researched. Pearcy's assessment of the present state of (...) classics in America strikes me as overly bleak, but his analysis deserves our close attention. Chapters 1 and 2, which trace the history of classical studies in Europe and America since the Renaissance, are filled with valuable information and insights; chapter 3 dissects four interlinked arguments that, to Pearcy's thinking, explain the parlous state of classics today—and threaten its future survival; and chapter 4 offers thoughtful suggestions as to how classicists might respond to these challenges. I doubt that most readers will agree with all of Pearcy's analysis—I certainly do not—but I found his book consistently stimulating. He writes that his purpose is to provoke a conversation, not to solve a problem (118); it is a conversation that will benefit us all, and this book is a welcome and timely catalyst.Pearcy's starting point, and the theme to which he repeatedly returns, is what he identifies as an essential difference between classical studies in Europe (including Great Britain) and classical studies in America. To quote from Pearcy's account of Vittorino da Feltre, whom he sees as an architect of what we now call "liberal education," classical education was designed above all "to take those who would... rule and those who might be admitted to the governing class and to form their minds and souls in such a way that they would be the best rulers (8)... "Renaissance classical education... [was] designed to educate members of the governing class by exposing them to the best patterns of conduct, modes of thinking, and products of culture..." (9). In Europe this form of education made sense in that its presupposition of a governing class matched the social and political realities of the countries in question. In America, by contrast, the advent of democracy undermined the central assumptions of such education and threatened its relevance to our society: "The necessary openness of thought in a democracy has a consequence that is fatal to [End Page 595] the paradigm of classical liberal arts education. In a democratic society, the freedom and theoretical equality of all citizens make it necessary to avoid privileging any single set of beliefs or ideas" (23).Pearcy's hypothesis is thought-provoking, but it strikes me as overly neat. A quick glance at two individuals, one English, the other American, offers some corroboration and also raises some intriguing questions. Leonard Woolf majored in classics at St. Paul's School and Cambridge, and, though his origins were not "aristocratic," upon graduation he entered the ranks of the governing class as a civil servant in Ceylon. The progression matches Pearcy's model, and Woolf even comments on it in terms similar to those Pearcy uses: "The male members of the British aristocracy of intellect went automatically to the best public schools, to Oxford and Cambridge, and then into all the most powerful and respectable professions."1 By contrast, S. S. McClure, the American publisher, migrated from Ireland to the States at age nine as a virtual pauper, spent eight years putting himself through Knox College, and chose to major in classics for reasons similar to those Pearcy identifies as the basis for classical education: "During the years that he reads and studies Greek a boy gets certain standards that he uses all the rest of his life, long after he has forgotten grammar and vocabulary."2 Unlike Woolf, however, McClure found to his dismay that though he had graduated third in a class of thirty, his classical education did not open doors to a professional career: "I talked with other boys, and found that most of them had arranged for the immediate future. One classmate was going into his father's law office; another was going to enter his uncle's... (shrink)

Renaissance and Baroque, two terms unknown in the ages they describe, are now an integral part of the general public's cultural vocabulary. The first encompasses European civilization from the mid-fifteenth century to around 1550, and the second refers to developments in the seventeenth century, with the intervening fifty years forming a period of transition termed Mannerism. Beginning with the appearance of Heinrich Wölfflin's Kunst geschichtliche Grundbegriffe in 1915, these two great epochs of intellectual development have been described quite successfully by (...) juxtaposing the one with the other. Wölfffin, for example, saw five great categories of discrimination between the two, namely Linear and Painterly, Plane and Recession, Closed and Open Form (Tectonic and A-tectonic Form), Multiplicity and Unity (Multiple Unity and Unified Unity), and Clearness and Unclearness (Absolute and Relative Clearness). More recently, Wylie Sypher in Four Stages of Renaissance Style has extended the list with the polar characteristics of Cyclic-Broken (Cyclothym-Schizothym), Exact-Abstract (Representational-Nonrepresentational), Visual-Haptic, Nearseeing-Farseeing, Dark-Light, Horizontal/Vertical-Oblique/Spiraling, and Points/Lines-Planes/Volumes.

In Newcomb’s paradox you can choose to receive either the contents of a particular closed box, or the contents of both that closed box and another one. Before you choose though, an antagonist uses a prediction algorithm to accurately deduce your choice, and uses that deduction to fill the two boxes. The way they do this guarantees that you made the wrong choice. Newcomb’s paradox is that game theory’s expected utility and dominance principles appear to provide conflicting recommendations for what (...) you should choose. Here we show that the conflicting recommendations assume different probabilistic structures relating your choice and the algorithm’s prediction. This resolves the paradox: the reason there appears to be two conflicting recommendations is that the probabilistic structure relating the problem’s random variables is open to two, conflicting interpretations. We then show that the accuracy of the prediction algorithm in Newcomb’s paradox, the focus of much previous work, is irrelevant. We end by showing that Newcomb’s paradox is time-reversal invariant; both the paradox and its resolution are unchanged if the algorithm makes its ‘prediction’ after you make your choice rather than before.

This book offers a comprehensive description of how writers, in particular poets in nineteenth-century France, became increasingly aware of the visual element in writing from the point of view both of content and of the formal organisation of the words in the text. This interest encouraged writers such as Baudelaire, Mallarme and Rimbaud to recreate in language some of the vivid, sensual impact of the graphic or painterly image. This was to be achieved by organising texts according to aesthetic criteria (...) so that as far as possible the form of the text as visually perceived would be closely interrelated to its content as reconstructed through the reading process. The result of this development was a radical redefinition of the scope and function of poetry, raising important general questions about the nature of the relationship between language and the visual image that are still very much of concern today.

This volume contains a close translation., suitable for students without a knowlegde of Greek, of the seventh and eigth books of Aristotle's Metaphysics, together with a philosophical commentary. In these difficult books, which are central to his metaphysical system, Aristotle discusses the nature of perceptible reality.

This book, written by a close friend, recounts episodes in the life and career of Eugene M. Shoemaker , an ever‐youthful geologist with a passionate interest in applying geological principles to the moon and planets. In the early 1960s Shoemaker persuaded the U.S. Geological Survey to found an Astrogeology Branch, of which he served as the first director, to search for impact scars on the earth and to map the moon and other planetary bodies. He also played a leadership (...) role in persuading NASA to include scientific investigations in its plans for the Apollo missions. In the 1970s, when images from spacecraft revealed the presence of impact craters on all the rocky planets and satellites, he declared that the impact of solid bodies was the most fundamental process to have taken place on the terrestrial planets. Acting on this insight, he helped to transform geology from an earth‐centered to a planetary science. Eugene Shoemaker was, indeed, a man who made an impact.Details of Shoemaker's career and his many accomplishments have been documented elsewhere, including the numerous citations for honors bestowed upon him and, sadly, his recent obituaries. In this book David Levy, an amateur astronomer and a collaborator with Gene Shoemaker and his wife, Carolyn, gives us personal reminiscences that are available nowhere else. Levy writes in a relaxed, anecdotal style that adds new information and a great sense of fun to this story.Levy tells us, for example, that as a young member of the U.S. Geological Survey, Gene broke with a stern tradition by bringing his wife and children to live with him in his field camps, arguing that their presence made him more rather than less efficient in conducting his work. It was perfectly natural, then, for Gene and Carolyn, decades later, to work together in the Australian outback, where they discovered ten previously unknown impact scars and confirmed several more suspected ones.From 1948 onward Gene harbored a fervent desire to go to the moon, a wish Levy ascribes to his view of a spectacular moonrise over the Colorado Plateau. Back then, such ideas were pure science fiction; but years later, when a real possibility arose, Gene was overcome by a mystifying loss of energy. When his doctor found nothing wrong, Gene and Carolyn took a river trip, hoping to restore his strength and spirits. But his condition worsened until he found a doctor who recognized, on sight, that Gene was a victim of Addison's disease, a formerly fatal illness that could be controlled by cortisone. On taking his second dose, Gene felt his energy returning, but he—like his contemporary President John Kennedy—was obliged to take cortisone every day for the rest of his life. This dashed Gene's hopes of going to the moon himself, but he redoubled his efforts to provide geological training to the fighter‐pilot astronauts who did go there.Beginning in the 1970s, Gene and Carolyn performed systematic searches of the night skies for comets and Near Earth Objects—bodies in orbits that might cause collisions with the earth. Levy joined in many of their searches, and the three of them shared the ultimate triumph of discovering their ninth comet together—Shoemaker‐Levy 9—and watching more than twenty luminous fragments of it plunge one by one into the atmosphere of Jupiter. Several of the pieces sent up dark plumes that lasted more than a year and would have been large enough to envelope the entire earth. No doubt remained that impacts could cause global damage to earth's lithosphere and biosphere were such impactors to strike our own planet. Levy tells us that as the last few pieces disappeared Carolyn lamented the loss of “her string of pearls”; as a consolation, Gene surprised her with the gift of a string of pearls.This book is not, nor was it intended to be, a serious biography based on extensive interviews and archival research. Regrettably, its excellence as a personal account is somewhat marred by the lack of attention from a good fact checker and editor, who would have fixed the slips that appear here and there. For example, on page 41 Levy describes Meteor Crater as being 1.2 kilometers across, and on page 43 as being 1.3 kilometers across—a small but needless discrepancy . On page 144 we read that when Gene brought a carload of students to the Grand Canyon, “a steady snow was falling as they made their way into the canyon. Gene showed a lot of enthusiasm—after all it was his crater!” Clearly, several sentences are missing from between these two sentences. Such lapses are minor, but they are sufficiently common to make the book unreliable as a source of facts. Nevertheless, it is a delightful book that can be strongly recommended to general readers and also to specialists, both for their enjoyment and for the personal details it will add to their knowledge of Eugene Shoemaker's contributions to science.

Weight systems on chord diagrams play a central role in knot theory and Chern-Simons theory; and more recently in stringy quantum gravity. We highlight that the noncommutative algebra of horizontal chord diagrams is canonically a star-algebra, and ask which weight systems are positive with respect to this structure; hence we ask: Which weight systems are quantum states, if horizontal chord diagrams are quantum observables? We observe that the fundamental gl(n)-weight systems on horizontal chord diagrams with N strands may be identified (...) with the Cayley distance kernel at inverse temperature beta=ln(n) on the symmetric group on N elements. In contrast to related kernels like the Mallows kernel, the positivity of the Cayley distance kernel had remained open. We characterize its phases of indefinite, semi-definite and definite positivity, in dependence of the inverse temperature beta; and we prove that the Cayley distance kernel is positive (semi-)definite at beta=ln(n) for all n=1,2,3,... In particular, this proves that all fundamental gl(n)-weight systems are quantum states, and hence so are all their convex combinations. We close with briefly recalling how, under our "Hypothesis H", this result impacts on the identification of bound states of multiple M5-branes. (shrink)

Acts are functions from states of nature into finite-support distributions over a set of ‘deterministic outcomes’. We characterize preference relations over acts which have a numerical representation by the functional J(f)=min>∫u∘ f dP¦PϵC where f is an act, u is a von Neumann-Morgenstern utility over outcomes, and C is a closed and convex set of finitely additive probability measures on the states of nature. In addition to the usual assumptions on the preference relation as transitivity, completeness, continuity and monotonicity, we (...) assume uncertainty aversion and certainty-independence. The last condition is a new one and is a weakening of the classical independence axiom: It requires that an act f is preferred to an act g if and only if the mixture of f and any constant act h is preferred to the same mixture of g and h. If non-degeneracy of the preference relation is also assumed, the convex set of priors C is uniquely determined. Finally, a concept of independence in case of a non-unique prior is introduced.

Poetry and philosophy have had a close but uneasy relationship in the western tradition. Both share an eschewal of the discovery of novel facts, but are somewhat opposed in that discovery is a central aim of poetry, but not at all the aim of philosophy. Through a close reading of W.H. Auden’s ‘In Memory of W.B. Yeats’ and a versification of part of G.E. Moore’s ‘A Defence of Common Sense’, I argue that what poetry shows corresponds, in a (...) broadly symbolist sense, to Wittgenstein’s understanding of the miraculous nature of the world. In this regard, poetry can offer philosophy clarity, in the form of its tonal architecture, value, and ethics, and may also constitute a perspicuous representation. Poetry remains in a perpetual mode of potential, as well as being possessed of a vatic autonomy. (shrink)

Given any subset A of ω1 there is a proper partial order which forces that the predicate xA and the predicate xω1A can be expressed by -provably incompatible Σ3 formulas over the structure Hω2,,NSω1. Also, if there is an inaccessible cardinal, then there is a proper partial order which forces the existence of a well-order of Hω2 definable over Hω2,,NSω1 by a provably antisymmetric Σ3 formula with two free variables. The proofs of these results involve a technique for manipulating the (...) guessing properties of club-sequences defined on stationary subsets of ω1 at will in such a way that the Σ3 theory of Hω2,,NSω1 with countable ordinals as parameters is forced to code a prescribed subset of ω1. On the other hand, using theorems due to Woodin it can be shown that, in the presence of sufficiently strong large cardinals, the above results are close to optimal from the point of view of the Levy hierarchy.

Adrian Stokes , long admired by a small, highly distinguished, mostly English circle, was the natural successor to Pater and Ruskin. But though his place in cultural history is important, what is of particular interest now to art historians is his theory of the presentness of painting, a theory which offers a challenging critique of the practice of artwriting. From Vasari to the present, the most familiar rhetorical strategy of the art historian is the narrative of “the form, prophet-saviour-apostles,” in (...) which the first artist poses some problem that his successors develop and their successors solve.1 Such very different books as Art and Illusion and Art and Culture deploy that plan. The three periods of naturalism in E. H. Gombrich’s narrative—antiquity, Renaissance religious narrative, nineteenth-century landscape—function like Clement Greenberg’s sequence—old master art, early French modernism, American abstract expressionism. Gombrich and Greenberg disagree about how to narrate art’s history and about which works to include in that narrative—Gombrich asserts that cubism closes the canon while for Greenberg analytical cubism anticipates Jackson Pollock—but in each case, the art historian aims, as the novelist does, to tell a satisfying story and achieve narrative closure, and so how we think of the artworks the historian discusses depends in part upon the structure of the narrative. In a certain mood, we may find this fact intolerable. Why should a mere text tell us how to see the painting we may stand before?Stokes’ attempt to respond to this mood belongs to a tradition of early twentieth-century antihistorical thinking. For Rainer Maria Rilke, Rodin’s sculpture aimed to “refer to nothing that lay beyond it.” For Ezra Pound, an image “is real because we know it directly”; Henri Gaudier-Brzeska could read Chinese ideograms without knowing that language because those ideograms are transparently meaningful images. For Wyndham Lewis, a musical piece is inferior to a statue, “always there in its entirety before you.”2 Such an artwork need not be interpreted because it contains “within itself all that is relevant to itself.”3 All art is accessible to the gifted observer, and time is, in an interesting double sense, irrelevant. We see directly the meaning of works even from distant cultures; the visual artwork is experienced all at once, outside of time. If these claims are correct, what is the artwriter to do? Speaking of the Tempio Malatestiana, Hugh Kenner points to this issue:There is no description of the Tempio in accordance with good Vorticist logic: one art does not attempt what another can do better, and the meaning of the Tempio has been fully explicated on the spot by Agostino di Duccio with his chisel.4 1.

In lieu of an abstract, here is a brief excerpt of the content:Working with Patience:An Insight into Dealing with Difficult EmotionsDavid VilanovaAs the most trusted professionals in the nation, nurses are expected to care for their patients with empathy and freedom from bias. The reality is that nurses are human, and some form of implicit bias is inevitable. In my own experience, this issue has reared its head on several occasions. My nursing background is prominently in cardiac and intensive care. (...) Seeing patients at their most vulnerable has become a regular part of my practice. Among some of the most challenging cases for me have been when I assume care of a patient withdrawing from alcohol. As an adult child with close alcoholic family members, many instances of abuse and pain stick with me today and these are brought to the surface when I care for patients with alcohol use disorder. In most cases, I easily find a healthy balance between remaining an understanding-and-empathetic provider and protecting my emotional and mental health as I navigate ethical and moral issues. However, with this patient population, walking that fine line is especially challenging. How do I navigate and manage intensely personal emotions and biases while providing the high-quality care I vowed to deliver regardless of my patient's life choices, addictions, and illnesses? How do I maintain an appropriate level of neutrality and clarity as this patient's behavior and attitude spark emotional triggers? In other words, how do I take care of someone I don't like?Mrs. H was a middle-aged Hispanic woman, barely coherent, but speaking clearly enough that I could understand her slurred speech. Immediate dread washed over me as I realized my assignment included a patient withdrawing from alcohol. The patient's affect, incoherence, and aggression were all too reminiscent of a traumatic past I still work to heal from. My coworkers couldn't understand her insults and obscenities and were therefore unphased except for noting her unruly and erratic behavior. On the other hand, I could understand much of what she was yelling at me and any other staff who bravely walked into her room. My immediate thoughts were that this woman clearly did not want our help. My every attempt to enter her room, speak with her, and provide care were met with an all too familiar rejection and denial that she even had a problem. Yet here she was in a hospital room, and I was her nurse. She verbalized denial of drinking too much when told that she was being treated for alcohol withdrawal. She stated this denial more to herself than to the health care providers in the room, and it was reminiscent of the denial I have seen in my loved ones. This was ironic, I always thought, as the need for such self-deception in and of itself points to the fact that something may be wrong and worth addressing.But denial or not, today, this patient—Mrs. H, was entrusted into my care. She refused treatments and medications, and this put me in a complex ethical predicament—treating a patient that I do not like for the personal issues she reminds me of, and the treatment of a patient against their refusal, as she was deemed incapable of making her own decisions. The latter of these two issues was easiest to put aside. Legally, this patient needed to be treated through her alcohol withdrawal. Once her mental status cleared up, she could sign out against medical advice or choose to remain until a safe discharge plan was in place. There was a protocol and legal guidelines for this situation. However, no guidelines [End Page 10] truly exist when it comes to the management of a patient that you simply do not like. The result can be a near-instantaneous dread each time you must answer that patient's bed alarm, call light, or most basic needs. A negative bias takes over, and it would be an understatement to say that this affects the quality of care. Patients in situations like this—with providers who judge them as I have been guilty of—can easily become subject to derogatory remarks, health inequities, and biased labeling... (shrink)

The original proof of Gleason’s Theorem is very complicated and therefore, any result that can be derived also without the use of Gleason’s Theorem is welcome both in mathematics and mathematical physics. In this paper we reprove some known results that had originally been proved by the use of Gleason’s Theorem, e.g. that on the quantum logic ℒ(H) of all closed subspaces of a Hilbert space H, dim H≥3, there is no finitely additive state whose range is countably infinite. In (...) particular, if dim H=n, then on ℒ(H) there is a unique discrete state, namely m(A)=dim A/dim H, A∈ℒ(H). (shrink)

The Ohio State University Press is to be congratulated, and Lennon and Olscamp are to be thanked for this book. Nicholas Malebranche has always been a major philosopher on the Continent but he has been less well-known in recent times within the English-speaking world. The Search was twice translated into English at the close of the seventeenth century and Malebranche was widely read and commented upon in English in both the seventeenth and eighteenth centuries. John Locke wrote about Malebranche. (...) David Hume not only cites him, Hume's analysis of causation is thought to owe much to Malebranche's doctrine. Some of Berkeley's earliest critics took him to be a Malebranchist. A. A. Luce argued some years ago that Malebranche is one of the most important philosophical influences upon Berkeley. Accordingly it is a delight to have the full text available and I hope it will be possible to produce a paper-back version. This translation is based on the edition of the Oeuvres complètes de Malebranche under the general editorship of André Robinet. This includes definitive editions of the Recherche and the Éclaircissements edited by Geneviève Rodis-Lewis. (shrink)

This revision of an important and lucid account of the various systems of axiomatic set theory preserves the basic format and essential ingredients of its highly regarded original. Quine's innovative exploitation of the virtual theory of classes in order to develop a considerable portion of set theory without ontological commitment to the existence of classes remains unchanged. So, too, does the list of topics treated--the theory of sets up to transfinite ordinal and cardinal numbers, the axiom of choice and its (...) equivalents, and a beautiful comparison of the various major formulations of set theory. There have, however, been a number of important changes, generally in the interest of greater elegance and clarity. One of the most notable of these is in the treatment of ordinal numbers. In the fourth section of that chapter an axiom schema is added to the effect that if α is a function and x an ordinal number, then there exists a class identical with the image of x under α. Although Quine, in general prefers to limit his existence assumptions as severely as possible, this added item possesses two attractive and closely related advantages: it yields the existence of all classes up to the size of any ordinal, and it greatly simplifies the subsequent treatment of ordinals and of transfinite recursion. The treatment of this latter subject, incidentally, has also been extensively modified to square with some difficulties first pointed out by Charles Parsons in The Journal of Symbolic Logic in 1964. Another important change consists in a considerable reworking of the section on infinite cardinals. The result is a more simplified and natural treatment. Finally, some new material on the theory of types and consequences of the axiom schema of comprehension has been added. Particularly with regard to the theory of types, this new material--due largely to the work of David Kaplan--has enabled Quine to drop, at one point, the assumption that there exists an object of lowest type. Altogether, this is a generally improved version of an originally masterful and brilliant work.--H. P. K. (shrink)

Schindler and Jr. Nicholas J. HealyBarrett H. TurnerFreedom, Truth, and Human Dignity: The Second Vatican Council’s Declaration on Religious Freedom: A New Translation, Redaction History, and Interpretation of “Dignitatis humanae.” By David L. Schindler and Nicholas J. Healy, Jr. Grand (...) Rapids, Mich.: Eerdmans, 2015. Pp. xiv + 477. $45.00 (paper). ISBN: 978-0-8028-7155-8.“I fear that you are going to give the inaccurate impression that this document was exclusively the work of the Americans at the Council, or nearly so,” wrote Ernest Primeau, an American bishop who helped revise Dignitatis humanae (DH) at Vatican II, to a priest-journalist. “The truth is... that many others from other nations played an important role in the writing and passage of the declaration.” Despite Primeau’s warning, popular and scholarly interpretations of DH have often hewed closely to John Courtney Murray’s juridical approach, usually in contrast to the integralism of Cardinal Alfredo [End Page 309] Ottaviani and the Spanish episcopate. Yet “many others” did not fit into those two groups, for a large contingent of bishops favorable to religious liberty nonetheless sought to undergird the juridical reasoning for the right with an ontological foundation.David L. Schindler and Nicholas Healy promote these other voices in Freedom, Truth, and Human Dignity. Indeed, they argue that the other voices—the “French” or “ontological” school comprised of bishops such as Alfred Ancel and Karol Wojtyła—provide the true key to DH’s meaning and significance. The book thus responds from the perspective of Communio theology to Murray-ite political theologies that are critical of John Paul II’s emphasis on truth as the basis for freedom. Accompanying Schindler’s and Healy’s essays are conciliar texts charting the origin and influence of this ontological school: the six conciliar drafts, the oral and written interventions of Wojtyła, and an oral intervention of Ancel. These texts, transcribed from the Acta Synodalia Sacrosancti Concilii Oecumenici Vaticani II (AS), have been translated by Patrick T. Brannon, S.J., and Michael Camacho. Also included is a side-by-side comparison of the third and sixth drafts that displays the changes made to the juridical position in response to the ontological school.Schindler’s 170-page essay, “Freedom, Truth, and Human Dignity: An Interpretation of Dignitatis Humanae on the Right to Religious Freedom,” is the heart of the work. Schindler recapitulates in a fresh way themes from his prior analyses of liberalism and Murray. In section 1, he summarizes how Wojtyła’s interventions influenced the evolution of DH such that Murray’s juridical approach became subordinated to an emphasis on truth as the foundation and telos of freedom. He conveys Wojtyła’s concern that DH not divide reason and revelation, but that reason be presented as capable of knowing that religion is “nature’s crown and summit” (50). Section 2 outlines Murray’s postconciliar objections to DH’s final version, namely, that it assumes that the American juridical approach leads to relativism and that its insistence on truth as religious liberty’s foundation undermines the universality of the right by degrading the liberty of those in error. To the first, Schindler replies (in section 3) that Murray’s juridical approach necessarily entails what Servais Pinckaers, O.P., called the “freedom of indifference,” Murray’s denials of relativism notwithstanding. The juridical approach leads to the conception of civil space as something neutral to truth-claims about God, but finally results in a state-enforced indifferentism that limits the religious liberty of those who hold that all of existence, prior to human freedom, is intrinsically ordered to God. “The human act, considered from the perspective of the juridical order, is first empty; and truth thus becomes, from that same juridical perspective, adventitious, something that, as such, cannot but logically burden the free-intelligent human act by arbitrarily limiting and closing what is considered by government, for legal purposes, to be simply open, or abstracted from all (metaphysical-religious) content...

In lieu of an abstract, here is a brief excerpt of the content:150. HUME AND COLLINS ON MIRACLES Some portions of 18th century intellectual history seem like puzzles of which the most important pieces are missing. In some lucky instances the pieces have not been lost altogether but only misplaced in some other puzzle, so that once this is recognised it is possible to solve both puzzles at once. The following, I believe, may comprise one such case. In his erudite (...) History of Freethought (London 1936), p. 757, J. M. Robertson presents us with the first puzzle:...seven years before the issue of Hume's Essay on Miracles, we find the thesis of that essay tersely affirmed in a note, to Book II of an anonymous translation (ascribed to T. Francklin) of Cicero's De Natura Deorum. The passage is worth comparing with Hume: "Hence we see what little credit ought to be paid to facts said to be done out of the ordinary course of nature. These miracles [cutting the whetstone, etc., related by Cicero, De Div i, c. xvii] are well attested. They were recorded in the annals of a great people, believed by many learned and otherwise sagacious persons, and received as religious truths by the populace; but the testimonies of ancient records, the credulity of some learned men, and the implicit faith of the vulgar, can never prove that to have been, which is impossible in the nature of things ever to be." M. Tullius Cicero Of the Nature of the Gods... with Notes, London, 1741, p. 85. The ascription to Thomas Francklin seems to have been drawn primarily from the "new edition" (London: T. Davies, 1775), on the title-page of which the translation and notes are said to be "By the Rev. Dr. Francklin". Also relevant to 151!. this attribution are these two facts: (1) that Thomas Francklin' s father, Richard Francklin, originally printed the book in 1741, and (2) that Thomas later translated other classical authors into English, notably Sophocles in 1759. But it is surely puzzling that Thomas, who in 1741 was barely twenty years old, and soon to be ordained and later made a Doctor of Divinity, should anticipate Hume's famous criticism of miracles. Consider now the second puzzle. It concerns Anthony Collins, the "Goliath of Freethinking" - as T. H. Huxley called him. In his Scheme of Literal Prophecy Considered (London, 1727) Collins promised a discourse on miracles "which is almost transcribed" (p. 439); and, indeed, it was about time, since by that date Collins had attacked nearly every other part of the Christian edifice. But no such work ever appeared in Collins' s lifetime. Nor is this the only book which Collins came close to publishing. From private letters of Collins' s in the British Library (MS 4282) we learn that he planned to publish an annotated translation of two of Cicero's writings. Thus in a letter of 26 September 1721 he speaks of "publishing my translation of Cicero's books of ye Nature of the Gods and of Divination" For "Nothing [he writes in the same letter] can more tend to promote good sense in the world than some of his [Cicero's] Philosophical Works; which are applicable to all sorts of folly and superstition by those who have Eyes to see and Ears to hear." The reader will now probably guess my drift: Collins was responsible for the 1741 edition of Cicero and its acute comment on miracles. But why, it will be asked, has this connection not been made before? The obvious answer is that since Collins died in 1729 twelve years separated his name from the 1741 edition. The evidence which firmly connects him with it is to be found (a) on the last page (279) of his Historical and Critical Essay on the Thirty Nine Articles (London 1724): "Speedily will be published, Cicero's Treatises of the 152. Nature of the Gods and of Divination. Translated into english [sic], with annotations. In two volumes." and (b) on the title-page. For the Historical and Critical Essay was printed by none other than R. Francklin, the very one who printed the 1741 edition of Cicero. That this is no coincidence - and Richard Francklin was to print... (shrink)

In this paper I explore a positivist methodological tradition in early demand theory, as exemplified by several common traits that I draw from the works of V. Pareto, H. L. Moore and H. Schultz. Assuming a current approach to explanation in the social sciences, I will discuss the building of their various explanans, showing that the three authors agreed on two distinctive methodological features: the exclusion of any causal commitment to psychology when explaining individual choice and the mandate to test (...) the truth of demand theory on aggregate data by statistical means. However, I also contend, from an epistemological point of view, that the truth of demand theory was conceived of in three different ways by our authors. Inspired by Poincaré, Pareto assumed that many different theories could account for the same data on individual choice, coming close to a kind of conventionalism -though I prefer to refer to this position as theoreticism. Moore was himself akin to Pearson's approach, which could be named descriptivist insofar as it resolved scientific laws into statistical descriptions of the data. Finally, Schultz tried to reconcile both approaches in an adequationist stance with no success, as we shall see. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:THE 'NATURALNESS' OF NATURAL RELIGION Among Hume's philosophical works the Dialogues Concerning Natural Religion is unquestionably the easiest to read. One can easily imagine a precocious fifteen-year-old like Miss Jane Austen — who set herself to write her own History of England only a decade or so after Hume's death — coming upon the little volume that nephew David published, reading it with great excitement (and a steadily (...) rising intellectual fury), and recording the same verdict that Pamphilus offers us, but in much more 2 trenchant terms. we can also imagine her reading it again twenty years later, armed with an explanatory commentary like the one that Stanley Tweyman has now given us, and maintaining her position (this time in the more temperate terms of Pamphilus himself). For Miss Jane Austen at thirty-five had one of the most critically commonsensical minds of her time; and she was also a person of deep religious feeling. It is in defence of her feelings, rather than of my own, that this essay is written. For she was close enough to what I take to have been Hume's position to have agreed with it once she had understood it; I, on the other hand, am not. To claim that a meeting of minds between the Rector of Steventon' s daughter and the Scottish apostle of infidelity is even conceivable may seem ridiculous. Hume himself would never have thought it likely. But even if my estimate is unduly optimistic, it serves at least to underline the importance of Tweyman' s constructive commentary. For without Tweyman 's commentary, Jane Austen's reaction to the Dialogues would have been one of morally indignant, and quite categorical rejection at any age. With it to guide her, she would have been appreciative and sympathetic, even if she was still ultimately dissatisfied. (I hope to persuade those who admire them both, as I do, that David Hume and Jane Austen belonged to the same 'invisible Church'). To read the Dialogues is still relatively easy. We only have to know that we are listening to a conversation between educated men in a society where everyone professes (at least) to believe that the world they were born into was created by a God who is all-knowing and all-powerful, infinitely wise, infinitely just and good, and, above all, infinitely loving towards the only creatures in his world who are capable of recognizing what he has done for them. The Rector of Steventon's daughter would have had difficulty in appreciating the discussion properly, because she had some further, more specific, beliefs about God's relations with his beloved children. We have some (smaller) difficulties now, because we are far from believing so much (and many of us believe nothing of the sort at all). But to grasp what we are supposed to believe is not difficult; and once we know that, the conversation itself is easy to follow. Only once does it seem to get out of hand to the point of actual implausibility; and there are only three things about it that are genuinely puzzling. The conversation does not reach any conclusion — at least none that convinces us. We are not convinced because the obvious solution for the most pervasive of our three puzzles is the assumption that Philo, the speaker who appears to state an agreed conclusion, is only pretending. That he should pretend is quite right and proper for a modern philosophical dialogue. Augustine may have written straightforward expository (or 'dogmatic') dialogues; and Berkeley, following in the wake of some of Augustine's medieval imitators, may have managed to raise this form into the best imitation of a live discussion that has been achieved for the dogmatic dialogue in English. But the religious doctrine of these 'dogmatists' was orthodox. One glance at the fortunes of the great Italian dialogue writers — Bruno, Galileo, Campanella — is enough to teach us that it was not prudent to let one's own doctrine win openly when one was teaching against the Church. Jane Austen would certainly have adopted the hypothesis that Philo's professions of religious feeling are hypocritical throughout the discussion. She would have assumed that Cleanthes... (shrink)

This paper takes issue with an influential interpretationist argument for physicalism about intentionality based on the possibility of radical interpretation. The interpretationist defends the physicalist thesis that the intentional truths supervene on the physical truths by arguing that it is possible for a radical interpreter, who knows all of the physical truths, to work out the intentional truths about what an arbitrary agent believes, desires, and means without recourse to any further empirical information. One of the most compelling arguments for (...) the possibility of radical interpretation, associated most closely with David Lewis and Donald Davidson, gives a central role to decision theoretic representation theorems, which demonstrate that if an agent’s preferences satisfy certain constraints, it is possible to deduce probability and utility functions that represent her beliefs and desires. We argue that an interpretationist who wants to rely on existing representation theorems in defence of the possibility of radical interpretation faces a trilemma, each horn of which is incompatible with the possibility of radical interpretation.

According to the Relevant Alternatives (RA) Theory of knowledge, knowing that something is the case involves ruling out (only) the relevant alternatives. The conception of knowledge in epistemic logic also involves the elimination of possibilities, but without an explicit distinction, among the possibilities consistent with an agent’s information, between those relevant possibilities that an agent must rule out in order to know and those remote, far-fetched or otherwise irrelevant possibilities. In this article, I propose formalizations of two versions of the (...) RA theory. Doing so clarifies a famous debate in epistemology, pitting Fred Dretske against David Lewis, about whether the RA theorist should accept the principle that knowledge is closed under known implication, familiar as the K axiom in epistemic logic. Dretske’s case against closure under known implication leads to a study of other closure principles, while Lewis’s defense of closure by appeal to the claimed context sensitivity of knowledge attributions leads to a study of the dynamics of context. Having followed the first lead at length in other work, here I focus more on the second, especially on logical issues associated with developing a dynamic epistemic logic of context change over models for the RA theory.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Mapping Beyond Measure: Art, Cartography, and the Space of Global Modernity by Simon FerdinandDavid TooheyMapping Beyond Measure: Art, Cartography, and the Space of Global Modernity BY SIMON FERDINAND Lincoln: University of Nebraska Press, 2019Mapping Beyond Measure is a geographical and theoretical critique of map art and the tradition of modern mapmaking. The book focuses in depth on a few related examples of map art and departs from critical (...) theory and post-Marxist readings of space. Simon Ferdinand emphasizes fine art and art-film as appropriate counterweights to the authoritarian calculation in modern cartography and, unexpectedly, map art’s critique of mapmaking.Mapping Beyond Measure follows the well-trodden path of critiquing a medium, mapping, and map art as irredeemably authoritarian.1 Situated in this approach, Ferdinand argues that map art reproduces modernist cartography’s assumptions even while critiquing mapping. Aiming to subvert this shortcoming, Ferdinand explores Peter Greenway’s semi-abstract map art films that do not prioritize science over artists. Greenway’s films, especially A Walk Through H, are shown as being as close to an idea of mapping beyond calculation as possible. Indeed, for Ferdinand, Greenway’s map art films are an improvement on “postmodern” theorists.Mapping Beyond Measure explores a small, though logically (and practically) related group of map artists. The first three chapters explore differing approaches to map art, from Soviet painting that unintentionally [End Page 126] heralds globalization and map art’s latent desires to dominate the world, to more contemporary map art about looming societal collapse through the death of nature and mass casualties from aerial bombardment of cities. The following two chapters focus on how mapping creates nation-states. These chapters elucidate the tragic inability of map artists to escape globalization and calculation, the latter exasperated by G.I.S. techniques. These map artists serve as an ensemble that spotlights what, to Ferdinand, are inevitable difficulties that ethical practitioners of map art face in escaping the pitfalls of calculation in mainstream mapping.In chapter 6 Ferdinand explains how Greenway’s film A Walk Through H gets as close as possible to challenging map art through semi-abstract, two-dimensional additions to maps and using movie cameras to create an illusion of movement. Thus, the hierarchy of scientists over artists is partially dismantled. Indeed, Ferdinand lauds Greenway for creating alternatives to established political theorists. Interestingly, Ferdinand replaces ontology with the concept of “chorein” suggesting a more fluid conception of mapping that is not available in theories of space or cartographic practices of calculation. Nonetheless, compared to one of the articles referenced, Ferdinand downplays the destructive nature of chorein as a militaristic, colonial use of maritime space to emphasize its creative potential.2Ferdinand’s examples are primarily Eurocentric, even, surprisingly, in the exception: his focus on Japanese map artist Satomi Matoba. Here Ferdinand departs from Eurocentric examples only to focus on Japan—the most privileged nation-state in Asia. Even in this focus on Japan, which also includes Hawai‘i, Ferdinand does not depart from a frame familiar to Europe: World War II. Indeed, the discussion of Pearl Harbor (a U.S. military base) focuses on U.S. foreign policy, not on Hawai‘i. This thematic choice is relevant to other map artists in Ferdinand’s book. Ferdinand’s critique of calculability is based mainly on the consequences of Nazism, as theorized by Stuart Elden. However, Ferdinand’s theoretical interventions on uneven development in maps and map art would have been more substantial with the addition of detailed, localized, narrative accounts of violence suffered by non-white populations in Hiroshima, Nagasaki, and various European cities. Instead, we get an anonymous logic of maps that uses the idea of the past and potential [End Page 127] future destruction of cities to assume that everyone suffered to the same extent in World War II.While I am reluctant to criticize a book for not offering a solution to what it critiques, to a certain extent, the solution offered by Ferdinand contradicts his normative critique of calculability. In exploring Alison Hildreth’s map art, Ferdinand praises nuanced, temporally layered artistic explorations of ecological destruction and extinction. Likewise, A Walk Through H, is... (shrink)

The traditional view that all logical truths are metaphysically necessary has come under attack in recent years. The contrary claim is prominent in David Kaplan’s work on demonstratives, and Edward Zalta has argued that logical truths that are not necessary appear in modal languages supplemented only with some device for making reference to the actual world (and thus independently of whether demonstratives like ‘I’, ‘here’, and ‘now’ are present). If this latter claim can be sustained, it strikes close (...) to the heart of the traditional view. I begin this paper by discussing and refuting Zalta’s argument in the context of a language for propositional modal logic with an actuality connective (section 1). This involves showing that his argument in favor of real world validity his preferred explication of logical truth, is fallacious. Next (section 2) I argue for an alternative explication of logical truth called general validity. Since the rule of necessitation preserves general validity, the argument of section 2 provides a reason for affirming the traditional view. Finally (section 3) I show that the intuitive idea behind the discredited notion of real world validity finds legitimate expression in an object language connective for deep necessity. (shrink)

The nature of causation has been one of the central questions of metaphysics since ancient times. This chapter looks at the arguments for Causal Anti‐Realism. Causation requires necessary connections between separate existences. David Hume argued that the ordinary conception of causation involves the separateness of the cause and effect. Hume had a further, closely related argument against the reality of causation. Authors' idea of causation is merely a confusion of several distinct concepts, namely, the concepts of regular succession and (...) contiguity among events, and the concept of a felt propensity on their own part to infer one thing from another. There are four objections to Universal Causation, one assuming Mereological Universalism, a second employing a pluralized version of Universal Causation, a third involving a chain principle, and a fourth including an argument against infinite causal regresses.

This article reviews the notion of 'noûs' and the verb 'noein' in pre-Socratic philosophy: it brings together research carried out since Kurt von Fritz's famous articles of 1945-1946, taking into account 20th and 21th centuries studies, in particular the ones of James H. Lesher, Shirley D. Sullivan, Rossana Stefanelli and Favio Stella. This paper also focuses on the conception of 'noûs' in the thought of Xenophanes, who links it with divinity and thus anticipates the important contribution of Anaxagoras. Finally, it (...) examines the conception of 'noûs' and 'noein' in Parmenides, in whose Poem it is closely linked to his conception of Being. (shrink)

The continuum function αmaps to2α on regular cardinals is known to have great freedom. Let us say that F is an Easton function iff for regular cardinals α and β, image and α<β→F≤F. The classic example of an Easton function is the continuum function αmaps to2α on regular cardinals. If GCH holds then any Easton function is the continuum function on regular cardinals of some cofinality-preserving extension V[G]; we say that F is realised in V[G]. However if we also wish (...) to preserve measurable cardinals, new restrictions must be put on F. We say that κ is F-hypermeasurable iff there is an elementary embedding j:V→M with critical point κ such that H)Vsubset of or equal toM; j will be called a witnessing embedding. We will show that if GCH holds then for any Easton function F there is a cofinality-preserving generic extension V[G] such that if κ, closed under F, is F-hypermeasurable in V and there is a witnessing embedding j such that j≥F, then κ will remain measurable in V[G].

This new edition includes three new chapters, updating the book to take into account developments in the field over the past fifteen years.

In several works on modality, G. H. von Wright presents tree structures to explain possible worlds. Worlds that might have developed from an earlier world are possible relative to it. Actually possible worlds are possible relative to the world as it actually was at some point. Many logically consistent worlds are not actually possible. Transitions from node to node in a tree structure are probabilistic. Probabilities are often more useful than similarities between worlds in treating counterfactual conditionals.

In this collection of provocative essays, historians and literary theorists assess the influence of Michel Foucault, particularly his History of Sexuality, on the study of classics. Foucault's famous work presents a bold theory of sexuality for both ancient and modern times, and yet until now it has remained under-explored and insufficiently analyzed. By bringing together the historical knowledge, philological skills, and theoretical perspectives of a wide range of scholars, this collection enables the reader to explore Foucault's model of Greek culture (...) and see how well his interpretation accounts for the full range of evidence from Greece and Rome. Not only do the essays bring to light the assumptions, ideas, and practices that constituted the intimate lives of men and women in the ancient Mediterranean world, but they also demonstrate the importance of the History of Sexuality for fields as diverse as Greco-Roman antiquity, women's history, cultural studies, philosophy, and modern sexuality. The essays include "Situating The History of Sexuality" (the editors), "Taking the Sex Out of Sexuality: Foucault's Failed History" (Joel Black), "Incipit Philosophia" (Alain Vizier), "The Subject in Antiquity after Foucault" (Page duBois), "This Myth Which Is Not One: Construction of Discourse in Plato's Symposium" (Jeffrey S. Carnes), "Foucault's History of Sexuality: A Useful Theory for Women?" (Amy Richlin), "Catullan Consciousness, the 'Care of the Self,' and the Force of the Negative in History" (Paul Allen Miller), "Reversals of Platonic Love in Petronius' Satyricon" (Daniel B. McGlathery), and an essay from Dislocating Masculinity (Lin Foxhall). (shrink)

When is it _explanatorily_ better to adopt a conjunction of explanatory hypotheses as opposed to committing to only some of them? Although conjunctive explanations are inevitably less probable than less committed alternatives, we argue that the answer is not ‘never’. This paper provides an account of the conditions under which explanatory considerations warrant a preference for less probable, conjunctive explanations. After setting out four formal conditions that must be met by such an account, we consider the shortcomings of several approaches. (...) We develop an account that avoids these shortcomings and then defend it by applying it to a well-known example of explanatory reasoning in contemporary science. (shrink)

From an ethical point of view, shared decision-making is preferable to either physician paternalism or patient sovereignty. The traditional model of doctor-patient communication is too directive and too unconcerned with the patient's values to support truly shared decision-making. The traditional distinction between rhetoric and sophistic can provide the basis for a new model of mutual persuasion that does not limit communication to information, and that avoids the spectre of manipulation.

This is the first of two papers that use off-training set (OTS) error to investigate the assumption-free relationship between learning algorithms. This first paper discusses the senses in which there are no a priori distinctions between learning algorithms. (The second paper discusses the senses in which there are such distinctions.) In this first paper it is shown, loosely speaking, that for any two algorithms A and B, there are “as many” targets (or priors over targets) for which A has lower (...) expected OTS error than B as vice versa, for loss functions like zero-one loss. In particular, this is true if A is cross-validation and B is “anti-cross-validation” (choose the learning algorithm with largest cross-validation error). This paper ends with a discussion of the implications of these results for computational learning theory. It is shown that one cannot say: if empirical misclassification rate is low, the Vapnik-Chervonenkis dimension of your generalizer is small, and the training set is large, then with high probability your OTS error is small. Other implications for “membership queries” algorithms and “punting” algorithms are also discussed. (shrink)

At least since Descartes, philosophers have been interested in the special knowledge or authority that we exhibit when we speak about our own thoughts, attitudes, and feelings. This book contends that even the best work in contemporary philosophy of mind fails to account for this sort of knowledge or authority because it does not pay the right sort of attention to the notion of expression. What's at stake is not only how to understand self-knowledge and first-person authority, but also what (...) it is that distinguishes conscious from unconscious psychological states, what the mental life of a nonlinguistic animal has in common with our sort of mental life, and how to think about Wittgenstein's legacy to the philosophy of mind.

A primary purpose of argument is to increase the degree of reasonable confidence that one has in the truth of the conclusion. A question begging argument fails this purpose because it violates what W. E. Johnson called an epistemic condition of inference. Although an argument of the sort characterized by Robert Hoffman in his response (Analysis 32.2, Dec 71) to Richard Robinson (Analysis 31.4, March 71) begs the question in all circumstances, we usually understand the charge that an argument is (...) question begging with reference to the beliefs of the person, or the sort of person, to whom the argument is directed.

This paper provides a new approach to inference to the best explanation based on a new coherence measure for comparing how well hypotheses explain the evidence. It addresses a number of criticisms of the use of probabilistic measures in this context by Clark Glymour, including limitations of earlier work on IBE. Computer experiments are used to show that the new approach finds the truth with a high degree of accuracy in hypothesis selection tasks and that in some cases its accuracy (...) is greater than hypothesis selection based on maximizing posterior probability. Hence, by overcoming some of the problems with the previous approach, this work provides a more adequate defence of IBE and suggests that IBE not only tracks truth but also has practical advantages over the previous approach. Applications of the new approach to parameter estimation and model selection are also explored. (shrink)

This chapter develops and defends a formal epistemology of conjunctive explanation by determining the conditions under which multiple distinct explanations are better than one. The general approach is to identify an appropriate measure of explanatory goodness that can then be applied to conjunctive explanations. If a conjunctive explanation is to be preferred it needs to have greater explanatory virtue (e.g., power or scope) with respect to the evidence, but this explanatory gain is insufficient on its own. Given a conjunctive explanation’s (...) greater complexity, it also has a cost associated with it and so a balance needs to be struck between the gain and the cost. This is achieved by employing a Bayesian measure proposed by I. J. Good. This chapter explores some properties of this measure and its application to the epistemology of conjunctive explanation. In so doing, it addresses the general question of whether it is desirable to have more informative, less probable hypotheses when seeking good explanations. (shrink)

Background: The proprioceptive neuromuscular facilitation reciprocal contraction pattern has the potential to increase the maximum rate of torque development. However, it is a more complex resistive exercise task and may interfere with improvements in the maximum rate of torque development due to motor skill learning, as observed for unidirectional contractions. The purpose of this study was to examine the cost-benefit of using the PNF exercise technique to increase the maximum rate of torque development.Methods: Twenty-six participants completed isometric maximal extension-to-flexion or (...) flexion-only contractions at the wrist. Ten of the assigned contractions were performed on each of three sessions separated by 48-h for skill acquisition. Retention was assessed with 5 contractions performed 2-weeks after acquisition. Torque and surface electromyographic activity were analyzed for evidence of facilitated contractions between groups, as well as alterations in muscle coordination assessed across test sessions. The criterion measures were: mean maximal isometric wrist flexion toque; the maximal rate of torque development ; root-mean-square error variability of the rate of torque versus torque phase-plane; the rate of wrist flexion muscle activation ; a coactivation ratio for wrist flexor and extensor sEMG activity; and wrist flexor electromechanical delay.Results: There were no significant differences between groups with respect to maximal wrist flexion torque, dτ/dtmax or RMSE variability of torque trajectories. Both groups exhibited a progressive increase in maximal strength and in dτ/dtmax from the start of acquisition to retention. RMSE was lowest after a 2-week rest interval. There were no significant differences between groups in the rate of muscle activation or the coactivation ratio. There was a reduction in coactivation that was retained after a 2-week rest interval. Alternatively, EMD was significantly greater in the experimental group across all sessions. However, both groups had a similar pattern of improvement to the third consecutive day of testing, but returned close to baseline value after the 2-week rest interval.Discussion: The wrist extension-to-flexion contraction pattern did not result in a greater maximal rate of torque development than simple contractions of the wrist flexors. There was no difference between groups with respect to motor skill learning. The main adaptation in neuromotor control was a decrease in coactivation, not the maximal rate of muscle activation.
