In his recently published book _Reading the Figural, or, Philosophy after the New Media_, D. N. Rodowick introduces the figural into the analysis of film and new media. The book contains revised versions of already published articles written in the 1980s and 1990s, [1] together with new material, and takes us on a journey through film theory and new media technologies to draw out the power of figuration in the coming digital age. Recognizing the 'tectonic shift' (205)currently (...) taking place from an analog to a digital culture, Rodowick convincingly argues that we need a set of new concepts and strategies capable of engaging with new media forms and effects, in order to develop 'creative strategies of resistance' (xvi) as part of a 'critical genealogy that may liberate new concepts for critiquing the permeation of capital into all areas of cultural experience'.

Rhythm perception involves strong auditory-motor connections that can be enhanced with movement. However, it is unclear whether just seeing someone moving to a rhythm can enhance auditory-motor coupling, resulting in stronger entrainment. Rhythmic priming studies show that presenting regular rhythms before naturally spoken sentences can enhance grammaticality judgments compared to irregular rhythms or other baseline conditions. The current study investigated whether introducing a point-light figure moving in time with regular rhythms could enhance the rhythmic priming effect. Three experiments revealed that (...) the addition of a visual cue did not benefit rhythmic priming in comparison to auditory conditions with a static image. In Experiment 1, grammaticality judgments were poorer after audio-visual regular rhythms compared to auditory-only regular rhythms. In Experiments 2 and 3, there was no difference in grammaticality judgments after audio-visual regular rhythms compared to auditory-only irregular rhythms for either a bouncing point-light figure or a swaying point-light figure. Comparison of the observed performance with previous data suggested that the audio-visual component removed the regular prime benefit. These findings suggest that the visual cues used in this study do not enhance rhythmic priming and could hinder the effect by potentially creating a dual-task situation. In addition, individual differences in sensory-motor and social scales of music reward influenced the effect of the visual cue. Implications for future audio-visual experiments aiming to enhance beat processing, and the importance of individual differences will be discussed. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Literature 26.1 (2002) 173-187 [Access article in PDF] Symposium: On Ken Burns's "Jazz" Jazz After Jazz: Ken Burns and the Construction of Jazz History Theodore Gracyk As all action is by its nature to be figured as extended in breadth and in depth, as well as in length; and so spreads abroad on all hands... so all narrative is, by its nature, of only one dimension; (...) only travels forward towards one, or towards successive points; narrative is linear, action is solid. Alas for our "chains" or chainlets, of "causes and effects." —Thomas Carlyle, "On History," 1830 Jazz and freedom are synonyms. —Mezz Mezzrow I JAZZ, A FILM BY KEN BURNS is a fascinating and monumental achievement. In this essay, I identify and critique some of the project's core assumptions. My principal target is the assumption that a specific essence of jazz underlies most (but not all) of the music that is regularly identified as jazz and that the historical unfolding of this essence is the true subject of a historical investigation of jazz. This assumption accounts for the project's otherwise puzzling suggestion that jazz history ended approximately thirty-five years ago.The most visible element of the historical project is the ten-part, nineteen-hour documentary, Jazz: A Film by Ken Burns. However, the historical project has three other public elements. The first is a book, Jazz: A History of America's Music. 1 Credited to both Geoffrey C. Ward and Ken Burns, the bulk of the book is the film's spoken text, which includes both a unifying narrative and numerous quotations. The book makes it clear that this text is primarily Ward's work. Second, there is a website that makes available extensive transcripts of many of the [End Page 173] seventy-five interviews conducted for use in the film. Third, there is a set of twenty-two compact discs, each giving an overview of an important jazz musician (e.g., one devoted to Count Basie, one devoted to Dizzy Gillespie). Highlights of these discs have, in turn, been assembled into a five-disc box set called Ken Burns Jazz. My aim is to reveal and examine the conceptual scaffolding that supports and organizes this vast, multifaceted project.What is the principal assumption of this historical project? The project consistently emphasizes the music's capacity to give audible embodiment to the idea of American democracy. At the same time, the project is less than forthcoming about the aesthetic assumptions embraced by Ward and Burns. Familiar and predictable arguments are introduced to justify the appellation of "art" and to address the issue of the purported death of jazz in the 1970s. However, these two strands of the larger argument may be at cross-purposes with the principal assumption and the ideology that jointly justify the project's status as jazz history.Let me begin by describing the principal assumption in some detail. While there is no reason to suppose that its source is Ken Burns or his chief collaborator, historian Geoffrey Ward, the following blurb was used to advertise the project: Jazz has been called the purest expression of American democracy; a music built on individualism and compromise, independence and cooperation. Join us for an exploration of jazz, America's greatest cultural achievement. In keeping with this theme, the narration and principal interviewees of the film are positioned to emphasize that jazz is an audible embodiment of the idea of American democracy. Let us call this idea the democracy thesis. It is placed as a frame around the whole film: Wynton Marsalis announces it in the opening minutes of the first episode, and then he reiterates it in fresh words at the end of the last episode. Although it is repeated with numerous variations, the democracy thesis proposes that jazz involves an ideal of democratic America, not the fact of life in America: jazz, Wynton Marsalis assures us, is "a glimpse of what America is going to be when it becomes itself. And this music tells you that it will become itself." 2 Jazz... (shrink)

William Storm reinterprets the concept of the tragic as both a fundamental human condition and an aesthetic process in dramatic art. He proposes an original theoretical relation between a generative and consistent tragic ground and complex characterization patterns. For Storm, it is the dismemberment of character, not the death, that is the signature mark of tragic drama. Basing his theory in the sparagmos, the dismembering rite associated with Dionysus, Storm identifies a rending tendency that transcends the ancient Greek setting and (...) can be recognized transhistorically. The dramatic character in any era who suffers the tragic fate must do so in the manner of the ancient god of theater: the depicted self is torn apart, figuratively if not literally, psychologically if not physically. Storm argues that a newly objectified concept of the tragic can prove more useful critically and diagnostically than the traditional and more subjective tragic "vision." Further, he develops a theory of the tragic field, a model for the connective and cumulative activity that brings about the distinctive Dionysian effect upon character. His theory is supported with case studies from Agamemnon and Iphigenia in Aulis, King Lear, and The Seagull. Storm's examination of the dramatic form of tragedy and the existential questions it raises is sensitive to both their universal relevance and their historical particularity. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Nuclear Power after Fukushima 2011:Buddhist and Promethean PerspectivesGraham ParkesDuring 2010 many environmentalists previously opposed to nuclear power were deciding, in the face of anthropogenic climate change from burning fossil fuels, that the only way to prevent runaway global warming would be to build more nuclear power plants after all.1 There are risks involved—though fewer than with carbon-based sources of energy.2 When one compares the detrimental effects (...) of nuclear power with those of burning fossil fuel, it is clear that the human injury and death toll (not to mention environmental devastation) resulting from the former have been nothing compared to the damage caused by the extraction and consumption of fossil fuels, owing to mining accidents, oil spills, and so forth—not to mention the massive carbon dioxide emissions.On the other hand, the problem of how and where to store the growing amount of radioactive waste from nuclear power plants, which remains deadly for many thousands of years, has yet to be solved. Costly security measures have to be taken to guard against terrorist attacks and theft of materials usable for nuclear devices. When full safety features are included, nuclear power plants become ever more expensive to build, and the costs of insuring them against accidents are so prohibitive that governments have to subsidize them, which they are increasingly unwilling to do.Not long after the explosions and meltdowns at the Fukushima Daiichi nuclear power station in March 2011, two dismal world records were announced: in 2010 we discharged a record amount of carbon dioxide (more than 30 gigatons) into the atmosphere, mainly by burning fossil fuels, and, as a direct consequence, carbon dioxide levels in the atmosphere (as measured at the Earth Systems Research Laboratory in Hawai'i) reached a record level of 395 parts per million. These figures suggest that we are continuing to generate a rise in global average temperatures that is already destroying the livelihoods of millions and will soon jeopardize the lives of hundreds of millions more.As a consequence of the 2011 Fukushima disaster, Japan—long a leading promoter of nuclear power—has begun to enforce some widely neglected safety regulations and is seriously reconsidering its reliance on nuclear energy. China has put construction of [End Page 89] new power plants on hold. Other nations (such as Germany, Italy, Switzerland, Thailand, and Malaysia) have decided to phase out or cancel plans to build more nuclear power stations. Yet the primary motivations remain unclear, since people's attitudes toward the dangers of nuclear radiation are anything but rational—as evidenced by the mass departure of foreigners from Japan after the catastrophe at Fukushima, when health dangers beyond the vicinity of the power station were minimal.In Europe, the reaction to the Fukushima disaster has clearly been aggravated by memories of the catastrophe at Chernobyl in 1986. While Chernobyl was a more widely destructive event than Fukushima, releasing a much greater amount of radioactivity, its effects on human health continue to generate disagreement. According to the third report on the effects of the Chernobyl catastrophe issued by the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR), among the 134 plant staff and emergency workers who suffered acute radiation syndrome (ARS), the condition proved fatal for twenty-eight of them. By 2006 another nineteen ARS survivors died, although their deaths were not directly attributable to the effects of ionizing radiation. Although the report attributes "a substantial fraction" of the six thousand cases of thyroid cancer in people who were children at the time of the accident to their consumption of milk contaminated with iodine-131, only fifteen cases had proved fatal by 2005, some twenty years later.3 The death toll, then, was fewer than fifty.By contrast, a study by a group of scientists from Belarus, Russia, and the Ukraine, Chernobyl: Consequences of the Catastrophe for People and the Environment, estimates the number of deaths attributable to the meltdown at around 980,000—almost twenty thousand times greater than the estimate by the UN scientific committee.4 What are we to make of this vast discrepancy, especially since the UNSCEAR report "was prepared in close cooperation with...

After this, his twelfth film, Kurosawa's reputation was firmly established in international cinema, and Rashomon continues to be discussed and imitated more than sixty years (...) class='Hi'>after its first screening. This volume addresses issues beyond the realm of Rashomon within film studies, and to do with the Rashomon effect which itself has become a widely recognized English term referring to significantly different perspectives and interpretations of different eyewitnesses to the same dramatic event. The dual figures of ripples and circles comprise the organizing image and principle of this book as each chapter addresses either the movement of ripples, representing the continuing and vibrant influence of Rashomon effects into the twenty-first century, or of circles, representing specific events, such as the publication of a new script, a particular production, or a remake.

This article examines the influence of the Hanafī philosophy of the Mamlūk period on the early Ottoman fiqh studies. Since the Egyptian and Damascus regions, which were under the rule of the Mamlūks, became the most important centres of knowledge in the Islamic world, it is understood that the Mamlūks’ scientific knowledge was superior to the Ottomans. On this occasion, many scholars who were considered the leading figures of the Ottoman scientific community turned to Egypt and Damascus regions and benefited (...) from the scientific accumulation there. In fact, these scholars who played an active role in the formation of the Ottoman scientific environment completed their education in Damascus and Egypt under the rule of the Mamlūks and graduated from the Mamlūk education system and assumed important roles in the formation of the Ottoman science understanding. During this period, the Hanafī judges (fuqahāʾ), who were active in the Mamlūk community, contributed to the development of the leading names of the Ottoman scientific community and this thought had an impact on their understanding of science. In this context, it is possible to say that the fiqh studies of the Ottomans in the first period were influenced by the Mamlūk Hanafī who had their characteristics. The two main characteristics of Hanafī thought in the Mamlūk period, the hadīth-centred juristic (fiqh) idea and the method of mamzûc (mixed) fiqh style are also seen in Ottoman fiqh works.Summary: In this article, the effect of Hanafī fiqh thought on the early Ottoman fiqh studies in Mamlūk period is discussed. While the Ottomans did not yet establish a scientific tradition in the period of foundation and ascension, many Mamlūk cities replaced Baghdad as the centre of knowledge of the Islamic world. Because the Mongol invasion, the crusades and the destruction of Andalusia due to reasons such as many scholars displaced by the Mamlūks settled there. Especially during this period, Egypt and Damascus, which were under the rule of the Mamlūks, became the most important centres of science in the Islamic world. In this respect, 14th-16th It is accepted that the science level of the Mamlūks was quite superior to the Ottomans in the 16th century. On this occasion, many scholars who are considered as the leading names of the Ottoman scientific community turned to Egypt and Damascus regions and benefited from the scientific accumulation there. Osman Ghāzī’s teacher and father-in-law, Sheikh Edebālī, Davud-i Kayserī, Sheikh Bedreddin, Molla Fanārī, Molla Gürānī are some of these scholars. In addition to these, scholars such as Muhsin-i Kayserī, Germiyanlı Poet Ahmedī, Hacı Paşa, Celāleddin Hızır, İbnü’l-Cezerī and İbn Arabşāh have also studied science in Egypt and Damascus. These scholars, who played an active role in the formation of the Ottoman scientific environment, completed their education in Damascus and Egypt under the rule of the Mamlūk and after graduating from the Mamlūk education system, they played an important role in the formation of the Ottoman science understanding. Sheikh Edebālī was accepted as one of the scientific and spiritual leaders of the Ottoman Empire. Davud-ı Kayserī was the first chief professor of İznik madrasah, the first Ottoman madrasah. Molla Fanārī had the privilege of being the first Ottoman shaykh al-Islām. Molla Gürānī became the teacher of Fatih Sultan Mehmed. During this period, the Hanafi faculties, which were active in the Mamlūk science community, contributed to the growth of the leading names in the Ottoman science community. Molla Fanārī, Seyyid Şerif Cürcānī, Shaykh Bedreddin and Poet Ahmadī have learned lessons from Bābertī, who important Hanafī scholars in Egypt. The idea of Hanafī fiqh in the Mamlūk period influenced the studies of the Ottoman fiqh in the first period. In this context, Molla Khüsrev refers to Zeyla‛ī and Bābertī, the leading Hanafī scholars of Mamlūk in many parts of his work, although he did not go to the regions dominated by the Mamlūks. The two main characteristics of the Hanafī thought in the Mamlūk period were the hadith-centred fiqh thought and mamzûc (mixed) method of fiqh. In the Mamlūk period, hadith studies which were not seen before in Hanafī sect were done. During this period, Hanafī jurists spent time in the field of hadith such as Ibn Balabān, Ibn Turkmānī, Zeylaʻī, Kuraşī, Mogoltay b. Kılıç, Bedruddīn Aynī, Ibn Kutluboğa, Serūcī, Bābertī, İbnü’l-Humām, İbnü’l-‛Adīm. They tried to eliminate the lack of studies in the field of hadith in the Hanafī circles while their studies certainly require hadith expertise. As a result of the works of these jurists in the field of hadith, the basic sources were frequently included in the fiqh studies in the Mamlūk period and, the hadiths were started to be made. The influence of this understanding, which had an important place in the thought of the fiqh of Hanafī during the Mamlūk period, can be seen in the Ottoman fiqh works in the first period. In this context, Molla Khüsrev, in his work with the influence of the early Ottoman jurists who had been educated in Egypt before him, gave some basic sources of hadith and sometimes gave information about the reliability of hadiths. On the other hand, it is possible to say that this issue is quite insufficient in Ottoman fiqh works when compared with Hanafi jurists of the Mamlūks. A comparison of Ibnü’l-Humām’s Fethü’l-kadīr and Netāicu’l-efkār, which was performed by Kādızāde order to complete it, can be compared. Apart from that, there are different attitudes between Şürünbülālī and Şeykhi-zāde known as Damad Efendi, they lived in the same period. Şürünbülālī, one of the Egyptian scholars of the Ottoman period generally gave the hadiths from the basic hadith sources in his work Merāki’l-felāh, while Şeyhīzāde did not obey this issue and rarely included basic hadith sources in his work Mecma‛ü’l-enhur. These differences can be explained by the necessity of the scientific environment. Because the Hanafīs were accused of not using hadith in Egypt and its environs, the Hanafī jurists living in this region should have directed them to be more rigorous about the hadith. However, since the Hanafī jurists living in other Ottoman regions did not have such a problem, they probably did not feel the need to refer to the main sources of hadith in the power of hadiths. Therefore, it can be said that the scientific environment and the need arising in this direction lead to different attitudes of the jurists living in the same period. The mamzûc (mixed) method starting with Ibnu’s-Sāātī, In the 8th-century, it was especially effective on the idea of ​​the fiqh style of Hanafī jurists. Although the first name of the mamzûc (mixed) method, Ibnu’s-Sāātī, was not one of the scholars of the Mamlūk period, the influence he initiated was more common in the Mamlūk period and became one of the characteristic features of the Hanafī fiqh thought in this period. Therefore, it is understood that the majority of Hanafī jurists had a gratified method. In addition to this, it is seen that Ottoman jurists who were educated in and around Egypt write procedural works in grammatical style. Molla Fanārī's work Fusūlü’l-Bedāyi is the most important example of this genre. Moreover, even Molla Khüsrev, who had not gone to Egypt and his surroundings, wrote a memoir-like work called Mir’ātü’l-Usûl. The works of these two authors show that the Ottoman jurists were influenced by the Mamlūks. As a result, it is possible to say that the fiqh studies in the early period of the Ottomans were influenced by the Mamlūk Hanafīs who had their characteristics. The hadith-centred fiqh thought and mamzûc (mixed) fiqh style understanding had an impact on the early Ottoman fiqh studies. (shrink)

The Physical Exercise Rating Scale, Mindfulness Attention Awareness Scale, Ruminative Thinking Scale, and Pittsburgh Sleep Quality Index are used to conduct the questionnaire among a sample of 1,006 college students to figure out whether there is any correlation between physical exercise and sleep quality in college students as well as how the mechanism of mindfulness and ruminative thinking plays a role in them. For data analysis, the Harman single-factor test was used; for the common method deviation test, Pearson’s correlation analysis, (...) and the mediating effect tested by using the bootstrap method were carried out. Results: Overall, 34% of college students’ sleep quality is poor. The PSQI is positively correlated with ruminative thinking, while both are negatively correlated with the level of physical exercise and mindfulness; the level of physical exercise is positively correlated with the level of mindfulness. Physical exercise can significantly negatively predict sleep quality had no significant predictive effect on sleep quality. After controlling for age and gender, physical exercise appears to have an impact on sleep quality of college students through the independent intermediary role of mindfulness and ruminative thinking and the chain intermediary role of mindfulness and ruminative thinking, with a total mediating effect value of −0.007. This study reveals the relationship between physical exercise and sleep quality, as well as its mechanism, thus guiding college students to actively participate in physical exercise. It also provides corresponding suggestions to improve sleep quality as well as physical and mental health in college students. (shrink)

Assumption of risk - the notion that one cannot complain about a harmful state to which one has willingly exposed oneself - figures prominently in our extra-legal lived experience. In spite of its deep roots in our common-sense morality, the tort doctrine of assumption of risk has long been discredited by many leading tort scholars, restatement reporters, courts, and legislatures. In recent years, however, growing concerns about junk food consumption, and about obesity more generally, have given rise to considerations that (...) are traditionally associated with the principles underlying the doctrine of assumption of risk. Against this backdrop, I shall advance two claims: one negative and the other affirmative. The negative claim is that the major objections to the doctrine of assumption of risk are either misplaced or overblown. And affirmatively, I argue that this doctrine can provide an illuminating framework with which to address pressing social concerns such as the one associated with junk food’s harmful side-effects.

A powerful work of moral and political philosophy.The idea which I shall present here came to me more or less out of the blue. I was on a train some five years ago, on my way to spend a day at Headingley and I was reading a book about the death camp at Sobibor... The particular, not very appropriate, conjunction involved for me in this train journey... had the effect of fixing my thoughts on one of the more dreadful features (...) of human coexistence, when in the shape of a simple five-word phrase the idea occurred to me. In The Contract of Mutual Indifference, Norman Geras discusses a central aspect of the experience of the Holocaust with a view to exploring its most important contemporary implications. In a bold and powerful synthesis of memorial, literary record, historical reflection and political theory, he focuses on the figure of the bystander -- the bystander to the destruction of the Jews of Europe and the bystander to more recent atrocities -- to consider the moral consequences of looking on without active response at persecution and great suffering. Geras argues that the tragedy of European Jewry, so widely pondered by historians, social scientists, psychologists, theologians and others, has not yet found its proper reflection within political philosophy. Attempting to fill the gap, he adapts an old idea from within that tradition of enquiry, the idea of the social contract, to the task of thinking about the triangular relation between perpetrators, victims and bystanders, and draws a somber conclusion from it. Geras goes on to ask how far this conclusion may be offset by the hypothesis of a universal duty to bring aid. The Contract of Mutual Indifference is an original and challenging work, aimed at the complacent abstraction of much contemporary theory. It is supplemented by three shorter essays on the implications of the Jewish catastrophe for conceptions of human nature and progress and for certain types of Marxist explanation. (shrink)

We propose a new masking technique for masking word stimuli. Drawing on the phenomena of metacontrast and paracontrast, we alternately presented two prime displays of the same word with the background color in one display matching the font color in the other display and vice versa. The sequence of twenty alterations was sandwich-masked by structure masks. Using this masking technique, we conducted evaluative priming experiments with positive and negative target and prime words. Significant priming effects were found – for (...) primes and targets drawn from the same as well as from different word sets. Priming effects were independent of prime discrimination performance in direct tests and they were still significant after the sample was restricted to those participants who showed random responding in the direct test.

To the bulk of the British reading public ‘contemporary French philosophy’ would seem to be interchangeable with ‘the works of M. Bergson.’ And it can scarcely be otherwise when, as an erudite correspondent of Le Temps relates, Paris now prints in a week one million books—as many as were printed annually in the reign of the Roi Soleil. For the proportion of these devoted to philosophy is not small. One voracious reader and professor of philosophy in Switzerland, Monsieur J. Benrubi (...) , has withstood for thirty years the annual avalanche of philosophical books, read steadily on, abstracted and collated his gleanings. In him we have a most competent guide. Familiar with every rivulet and path, and with the historic formation of the country, he now reveals to us the whole panorama. His encyclopaedic enterprise, 1 treating some hundred and sixty authors, is neither a chronicle nor a classification, except in a secondary way. It aims principally at tracing cross-currents in recent philosophies so as to discover their internal connexions, and thence in what direction present French thought is heading. M. Benrubi's scrupulousness in seeing nobody is left out tends perhapsto overcrowding, and his emphasis on that which coheres may somewhat overshadow that which divides. And it may be inevitable, too, with a field of figures so vast, that the accounts of some should be insufficiently detailed. But the total effect is substantial, and his volumes are invaluable to whomever would appreciate whence and whither French thought is proceeding. There are three threads to guide us through the labyrinth. The distinct though still interacting tendencies are described as ‘empirical and scientific positivism,’ ‘epistemological and critical idealism,’ and ‘metaphysical and spiritual positivism.’ Each rests on certain characteristics manifested with varying explicitness in the thought of its many representatives. I indicate summarily and quite inadequately some points of M. Benrubi's conclusions. (shrink)

This article traces disagreements about the genetic effects of low-dose radiation exposure as waged by James Neel, a central figure in radiation studies of Japanese populations after World War II, and Yuri Dubrova, who analyzed the 1986 Chernobyl nuclear power plant accident. In a 1996 article in Nature, Dubrova reported a statistically significant increase in the minisatellite DNA mutation rate in the children of parents who received a high dose of radiation from the Chernobyl accident, contradicting studies that (...) found no significant inherited genetic effects among offspring of Japanese A-bomb survivors. Neel’s subsequent defense of his large-scale longitudinal studies of the genetic effects of ionizing radiation consolidated current scientific understandings of low-dose ionizing radiation. The article seeks to explain how the Hiroshima/nagasaki data remain hegemonic in radiation studies, contextualizing the debate with attention to the perceived inferiority of Soviet genetic science during the Cold War.

In lieu of an abstract, here is a brief excerpt of the content:A Bittersweet Score:A Father’s Account of His Family’s 20-Year Journey After a Pediatric Brain Tumor DiagnosisChristopher RileyI hadn’t seen him for 20 years, not since the day he drilled a hole in Peter’s head and left the stainless steel drill and bloody bit on the bedside table. He figured prominently in the story I often told of that day when he, a doctor in training, [End Page 3] (...) informed my wife Kathy and me that, “Wow,” our five-year-old son had “an impressive tumor” in his brain. He announced it with the admiration I reserve for a touchdown pass or stunning sunset. Since that day, he had become a venerable physician. Back then he was the resident who met us in the ER after our pediatrician told us that the MRI of Peter’s brain was “not normal,” that “there might be a growth.” As if there might not be. I imagined that Peter’s brain might simply have an unusual shape, or that the scan revealed some undiscovered fracture and the authorities only wanted to lock me up and all with my son would be well. The thrilled young doctor slew those hopes with an ice pick: “Wow, that’s an impressive tumor.” I said, “That’s the first time anyone has used the word tumor.” The doctor appeared mortified and started over.Now 20 years later we found ourselves at the same party and I felt a compulsion to introduce myself, remind him we’d met that day in 1993, and tell him what had become of Peter and his family in the decades since he’d made that mortifying mistake, one I hoped had become for him a defining moment. To my disappointment, he didn’t seem to remember.Peter was my red-haired boy. Fearless and whip smart, he told a stream of knock-knock jokes and performed dance routines choreographed by his 8-year-old sister Rachel. Six months of headaches, vomiting and clumsy falls led to discovery of the tumor. When I phoned my parents with the news, I couldn’t speak the words, words that felt as if they spelled my boy’s doom. My body refused to pronounce them.The war for Peter’s life began with surgery. I sat with Kathy in the surgical waiting area, fearing every minute that I would see the surgeon approaching with his shoulders slumped in mortal defeat. I learned during those hours that fear of your child’s death is a physical pain, a constriction in the chest, a suffocation. At the end of that wait, the surgeon told us the tumor was out and Peter had survived. The pathology indicated the tumor was a medulloblastoma. Without additional treatment, including radiation, it was certain to come back. Kathy’s knees buckled. Having just endured one life-and-death battle, we were plunged into another. To complicate matters, Peter wasn’t waking from surgery. Even after the anesthesia wore off, Peter remained groggy, unable to move or focus his eyes.Through the following days, Peter failed to rouse or speak. Sores formed at the back of his neck where his unswallowed saliva pooled. Neurologists doubted he knew us. His doctors hoped Peter would recover but it was possible he would remain as he was indefinitely. As I sat holding his useless hand, watching his useless body, I thought I’d never loved him as much as I did now.Peter’s doctors presented two treatment options. The first consisted of relatively high doses of daily radiation, the most effective known method for preventing the return of the cancer. But radiation wasn’t good for young brains. It “shaved IQ points,” they said in wild understatement. So they offered a second, experimental option, one that reduced radiation by a third and added months of chemotherapy. The doctors hoped this new regimen would be as effective as the old but cause less cognitive damage. They asked us to choose. It seemed impossible. We gathered the scant available data. We weighed the risks. We prayed. We took a leap. Without asking him, we made a decision for Peter we knew... (shrink)

Whereas the entrance of the monochrome into modern art has typically been understood in light of movements in contemporary art and aesthetic theory following in its wake, this essay seeks to understand the motivations for, and the effect of, the monochrome in the work of Aleksandr Rodchenko in 1921 in reference to Plato's analysis of pure pleasure and absolute beauty in the Philebus . I argue that Rodchenko and Plato were motivated by a shared project to contend with the aesthetic (...) and psychological effects of figurative semblance, or what Socrates calls the phantasm, in order to harmonize human perception with the world of sensuous material objects. It is in this shared project, I contend, that Rodchenko's strategy is to be understood as a kind of materialist Platonism that, when viewed phenomenologically, reveals Plato's objects of absolute beauty to be, in the context of industrial capitalism and the crisis of perception that Benjamin, among others, saw as its consequence, sites of loss and meaninglessness for modern consciousness, yet sites which nonetheless contain emancipatory potential for a social order that has been systematically alienated from itself and its environment.

Ecclesiazusae, the first surviving work of Aristophanes from the fourth centuryb.c.e., has often been dismissed as an example of Aristophanes’ declining powers and categorized as being less directly rooted in politics than its fifth-century predecessors owing to the after-effects of Athens’ defeat in the Peloponnesian War. Arguing against this perception, which was largely based on the absence of ad hominem attacks characterizing Aristophanes’ earlier works, this paper explores howEcclesiazusaeengages with contemporary post-war Athenian politics in a manner which, while (...) different to his earlier comedies, remained closely rooted in the political and cultural concerns of the 390s. By examining the figure of Praxagora, I will first consider recent suggestions thatEcclesiazusaehints at the possibility of an anti-democratic coup. I will then examine how contemporary discussions of constitutional and legal reforms (including the invocation of ‘founding fathers’ such as Solon and Lycurgus) are incorporated into both Praxagora's language and the scenes featuring the Selfish Man and Hags that follow the establishment of Praxagora's regime. Examining these final scenes, I conclude thatEcclesiasuzaedoes not suggest that the idea of democratic equality itself is fundamentally flawed, but instead argues that Athens needs a suitable leader, well suited to the rough and tumble of assembly rhetoric, in order to successfully function. In the world ofEcclesiazusae,the men of Athens have failed too often to inspire any hope, putting their own interest above the state, and the new leader must be someone different. Thus Aristophanes sets up Praxagora as a female Solon to remake the state and lead the democracy. The second half of the play demonstrates this need for a strong leader, as problems arise both from the quarter of critical bystanders (the Selfish Man and Epigenes, the Young Man in the ‘hag scene’) and from over-zealous enforcers (the Old Women).

A core feature of drug-resistant epilepsy is hyperexcitability in the motor cortex, and low-frequency repetitive transcranial magnetic stimulation is a suitable treatment for seizures. However, the antiepileptic effect causing network reorganization has rarely been studied. Here, we assessed the impact of rTMS on functional network connectivity in resting functional networks and their relation to treatment response. Fourteen patients with medically intractable epilepsy received inhibitive rTMS with a figure-of-eight coil over the vertex for 10 days spread across two weeks. We designed (...) a 6-week follow-up phase divided into four time points to investigate FNC and rTMS-induced timing-dependent plasticity, such as seizure frequency and abnormal interictal discharges on electroencephalography. For psychiatric comorbidities, the Hamilton Depression Scale and the Hamilton Anxiety Scale were applied to measure depression and anxiety before and after rTMS. FNC was also compared to that of a cohort of 17 healthy control subjects. The after-effects of rTMS included all subjects that achieved the significant decrease rate of more than 50% in interictal epileptiform discharges and seizure frequency, 12 patients with the reduction rate above 50% compared to the baseline, as well as emotional improvements in depression and anxiety. In the analysis of RSNs, we found a higher synchronization between the sensorimotor network and posterior default-mode network in epileptic patients than in healthy controls. In contrast to pre-rTMS, the results demonstrated a weaker FNC between the anterior DMN and SMN after rTMS, while the FNC between the aDMN and dorsal attention network was greater. Importantly, the depressive score was anticorrelated with the FNC of the aDMN-SMN, which was markedly different in the good and bad response groups treated with rTMS. Based on the vertex suppression by rTMS, it is possible to achieve temporary clinical efficacy by modulating network reorganization in the DMN and SMN for patients with refractory epilepsy. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:How Philosophers Trivialize Art: Bleak House, Oedipus Rex, "Leda and the Swan"Michael D. HurleyIIt is a Perverse but unsurprising irony that answers to the question of whether art can give us knowledge characteristically trivialize that which draws us to individual artworks in the first place. The experience of art is sidelined in favor of the apparent after-effect of that experience. Even those writing against each other tend to (...) converge on this. In an essay contesting Nelson Goodman's epistemic claims for art, Gordon Graham nonetheless agrees that, "The question to be asked of such a work is not, 'Does this effectively capture the scene portrayed?', but 'Does this make us see this sort of occasion differently?'"1 Even attempts to distinguish art as "gift" as opposed to commodity predictably figure its value in terms of what might be taken away: "I went to see a landscape painter's works, and that evening, walking among pine trees near my home, I could see the shapes and the colors I had not seen the day before."2This state of affairs is perversely ironic for two reasons. Firstly, because the possibility of art's cognitive content is only prompted at all by the immediate experience it offers: without this, art would not excite us the way it does and there would be no debate to be had. Secondly, and more significantly, because a defining part of what constitutes an interest in art is, I should like to suggest, an experience of knowledge; or, more accurately, an experience of knowing. This irony is unsurprising because it is merely another expression of a recalcitrant prejudice in western epistemology that idealizes knowledge as an objectively true, justified belief—perforce excluding the possibility of knowing as a subjective [End Page 107] experience of believing. No wonder the author of Theætetus elsewhere finds poets incapable of offering anything but lies.Plato's lingering legacy assures that the cognitive content of art be assized according to what might be extracted from the artwork—cashed in like so many casino chips—when we are done with our experience of it. This applies whether the knowledge-bearing being argued for, or against, is conceptual or propositional (e.g., Putnam, Novitz, John),3 or imaginative (e.g., Goodman, Robinson, Currie),4 as well as for the claim that art can offer us moral instruction (e.g., Beardsmore, Eldridge, Nussbaum, Sharpe, Kieran, John).5 There is less consensus as to whether the capacity of art to give us knowledge enriches the aesthetic value of that artwork, but those who would advance this position have been on the back-foot in recent years following a wave of criticisms from, among others, Beardsley, Lamarque and Olsen, Diffey, and Gaut.6This article addresses art's capacity to give us knowledge as well as the conjunct of whether such knowledge might inform its value qua art. In so doing, it presses a case that has already been disallowed by the terms in which the question of the relationship between art and knowledge is typically put. Whatever efferent knowledge art might offer, it also provides the conditions for a kind of knowing that cannot be translated beyond itself. Only such an experience of knowledge-as-knowing, which is realized through the untranslatable singularity of an artwork, may be considered constitutive of art's aesthetic value. Couched another way: epistemology meets aesthetics not where it has most often been located, in the perfective, at the congruence of the thought and the felt, but in the present continuous, in the engagement of thinking and feeling. Connecting the epistemic and the aesthetic in this way is, then, exactly the opposite proposition to that presented by Douglas Morgan, for whom, "although many words in many arts can and do give us knowledge of many kinds, nonetheless if this knowledge were the key and limit to the love of art, the world of art would be even sorrier than it now is."7IILiterature has generated by far the greatest volume of commentary in the debate on art and knowledge. This is to be expected given the bias towards categorizing knowledge as something like data... (shrink)

In this paper, I discuss the use of after-effects as a criterion for showing that we can perceive high-level properties. According to this criterion, if a high-level property is susceptible to after-effects, this suggests that the property can be perceived, rather than cognized. The defenders of the criterion claim that, since after-effects are also present for low-level, uncontroversially perceptual properties, we can safely infer that high-level after-effects are perceptual as well. The critics (...) of the criterion, on the other hand, assimilate it to superficially similar effects in cognition and argue that the after-effect criterion is a cognitive phenomenon rather than a perceptual one, and that as a result it is not a reliable guide for exploring the contents of perception. I argue against both of these views and show that high-level after-effects cannot be identified either with low-level after-effects or with cognitive biases. I suggest an intermediate position: high-level after-effects are not cognitive, but they are nonetheless not a good criterion for exploring the contents of perception. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Subjective Knowledge, Mental Disorders, and MedsHow to Parse the EquationMark D. Rego (bio)Keywordspsychopathology, antidepressants, suicidality, subjective experience, pre-reflectiveA few weeks, ago I was walking down the hall to my office when I spotted my brother-in-law coming the other way. This was odd on two accounts. First, he lives in Kentucky (I am in Connecticut) and second, he is at least a foot taller than the man in my hallway. (...) Nonetheless, I struggled to figure out why he was there. The resemblance was so striking it took me a minute or two to convince myself it was not him. Even after such convincing, the feeling that it was him remained.Later, I imagined that had I just returned from a crack cocaine den I would have been hypervigilant, if not paranoid, and consequently would be certain that my brother-in-law had arrived unannounced. Furthermore, I would probably assume that he was up to no good.How did I retain a strong feeling of recognition, the feeling that maybe it was really him, when I already concluded otherwise? And why, were I on crack cocaine, would the obvious facts be useless in rendering a decision about the identity of the man in the hall? Last, why would the post-cocaine man in the hall become a nefarious brother-in-law rather than a benign one?If I just computed some symbols to figure this out, wouldn't the feeling have gone away? If I activated a brother-in-law neural network, how did I come to acquire an evil brother-in-law neural network? And why wouldn't that go away either?In his article in this issue of Philosophy, Psychiatry, & Psychology, Hadreas looks at questions like these through the prism of before and after effects of people treated with selective serotonin reuptake inhibitors (SSRIs). Hadreas investigates the implications of a straightforward recomputation of self-awareness when treated with these medicines and finds such approaches unsatisfying and incomplete in their explanatory power. (My example looks at a type of awareness, but not specifically self-awareness, as does Hadreas. Furthermore, my paradigm asks about computational conclusions using language more common in psychiatric literature, whereas Hadreas uses standard philosophical terms. Although not isomorphic, I believe the interchange of the two remains true to the issues Hadreas is addressing). [End Page 57]In my example, there is clearly something else going on than the incorrect arrangement of symbols or the misfiring of nodes in a network that influences how I feel and what I think. Neither reason nor empiricism seem to serve me well here. Hadreas utilizes Husserl to begin to unpeel the layers of self-awareness and self-states that intermix to form the shifts and contradictions which are so common in psychiatric treatment (and in common experience as I describe).This is a welcome reckoning; the psychiatric literature is overflowing with unquestioned premises about the neuropsychiatric correlates of reason and empirical approaches (described more as computation and neural networks in the literature—again, not strictly analogous, but the same criticisms apply) Hadreas is critical of. Unfortunately, Hadreas has navigated through a sea of highly questionable assumptions about the psychopharmacology of depression to illustrate his points. This is due in large part to the common practice of consulting literary narratives and critics rather than one of immersion in the literature as a whole and the daily life of patients and active clinicians. He arrived at his destination despite this, because many of these details did not affect his particular analysis. However, to look forward to a continuation of this work and clarify some important issues I devote most of my commentary to these issues. The points I raise are more extensively discussed in a previous edition of this journal (Rego 2005).Affect to Reason ShiftLet's begin with the idea that SSRIs work by dampening emotions. An extension of this idea is that they dampen negative emotions and strengthen positive ones like assertiveness, confidence, and optimism. An even further development in this direction is that, by dampening strong emotions, cognitive enhancement takes place with SSRI treatment. A summary observation then is that SSRIs facilitate...

This volume starts where the four-volume work by Johannes Hoffmeister, Briefe von und an Hegel, left off. It consists of excerpts from letters, diaries, memoirs, newspaper and journal articles, etc., much of which has never been published before. What emerges is a conflicting picture of Hegel, the man--from which the reader can take his choice. The comments are from contemporaries: relatives, friends, acquaintances, students, colleagues, admirers, critics, and last, but not least, enemies. The chapters are organized chronologically by city of (...) residence, beginning with Stuttgart, 1770-1788, and covering the periods in Tübingen, Bern, Frankfurt, Jena, Bamberg, Nürnberg, Heidelberg, and Berlin. There is a special chapter on the period immediately following Hegel's death, and a final chapter on After-Effects. The biggest chapter by far is the one on the Berlin period, which spans the longest space of time and also covers the time when Hegel's fame had reached its zenith. All told there are 769 excerpts from the pens of such varied personalities as Karl, Christiane, and Marie Hegel, Hölderlin, Goethe, Schelling, Karl Rosenkranz, Eduard Zeller, Fichte, Schleiermacher, Schiller, Schlegel, Brentano, Savigny, Michelet, Schopenhauer, Victor Cousin, Heine, Feuerbach, Bouterwek, Varnhagen v. Ense, K. F. Zeller, Arnold Ruge, Ranke, Eduard Gans, and many others. This book will undoubtedly figure prominently in future biographies of Hegel. However, it is not only for the Hegel specialist. Those who are interested in that specific period of German culture and those who simply enjoy anecdotal historical commentary will find much of interest and amusement here.--H. B. (shrink)

Responding to bivalent stimuli slows subsequent performance. In prospective memory research, prospective memory targets can be considered as bivalent stimuli because they typically involve features relevant for both the prospective memory task and the ongoing task. The purpose of this study was to investigate how responding to a prospective memory target slows subsequent performance. In two experiments, we embedded the prospective memory task in a task-switching paradigm and we manipulated the degree of task-set overlap between the prospective memory task and (...) the ongoing task. The results showed consistent after-effects of responding to prospective memory targets. The specific trajectory of the slowing depended on the amount of task-set overlap. These results demonstrate that responding to prospective memory targets results in after-effects, a so far neglected cost on ongoing task performance. (shrink)

After decades of neglect philosophers of physics have discovered gauge theories--arguably the paradigm of modern field physics--as a genuine topic for foundational and philosophical research. Incidentally, in the last couple of years interest from the philosophy of physics in structural realism--in the eyes of its proponents the best suited realist position towards modern physics--has also raised. This paper tries to connect both topics and aims to show that structural realism gains further credence from an ontological analysis of gauge theories--in (...) particular U(1) gauge theory. In the first part of the paper the framework of fiber bundle gauge theories is briefly presented and the interpretation of local gauge symmetry will be examined. In the second part, an ontological underdetermination of gauge theories is carved out by considering the various kinds of non-locality involved in such typical effects as the Aharonov-Bohm effect. The analysis shows that the peculiar form of non-separability figuring in gauge theories is a variant of spatiotemporal holism and can be distinguished from quantum theoretic holism. In the last part of the paper the arguments for a gauge theoretic support of structural realism are laid out and discussed. (shrink)

After Napoleon's final defeat of 1815 and before the beginnings of the second great wave of French colonialism in the 1830s, during a period of great internal political crisis, French society produced an object called The Death of Sardanapalus. This painting represented what was then a somewhat familiar figure, the "Oriental," an outsider behaving badly and set to die for it.Based on the mimetic theory, this essay argues that in the relation it determines with its viewers, this painting's representation (...) of violence is a form of ritualistic activity, one that allows for contained and predictable events of unifying violence against outsiders. Among the effects of the French political conflicts was a crisis in such... (shrink)

We examine metonymy at psycho- and neurolinguistic levels, seeking to adjudicate between two possible processing implementations. We compare highly conventionalized systematic metonymy to lesser-conventionalized circumstantial metonymy. Whereas these two metonymy types differ in terms of contextual demands, they each reveal a similar dependency between the named and intended conceptual entities. We reason that if each metonymy yields a distinct processing time course and substantially non-overlapping preferential localization pattern, it would not only support a two-mechanism view but would suggest that conventionalization (...) acts as a linguistic categorizer. By contrast, a similar behavior in time course and localization would support a one-mechanism view and the inference that conventionalization acts instead as a modulator of contextual felicitousness, and that differences in interpretation introduced by conventionalization are of degree, not of kind. Results from three paradigms: self-paced reading, event-related potentials, and functional magnetic resonance imaging, reveal the following: no main effect by condition for either metonymy type immediately after the metonymy trigger, and a main effect for only the Circumstantial metonymy one word post-trigger ; a N400 effect across metonymy types and a late positivity for Circumstantial metonymy ; and a highly overlapping activation connecting the left ventrolateral prefrontal cortex and the left dorsolateral prefrontal cortex. Altogether, the pattern observed does not reach the threshold required to justify a two-mechanism system. Instead, the pattern is more naturally understood as resulting from the implementation of a generalized referential dependency mechanism, modulated by degree of context dependence/conventionalization, thus supporting architectures of language whereby “lexical” and “pragmatic” meaning relations are encoded along a cline of contextual underspecification.

A leading figure of the Scottish Enlightenment, George Campbell began what was to become his most famous work, The Philosophy of Rhetoric, soon after his ordination as a minister in 1748. Later, as a founder of the Aberdeen Philosophical Society, he was able to present his theories, and these discourses were published in 1776. In the spirit of the Enlightenment, Campbell combined classical rhetorical theory with the latest thinking in the social, behavioural and natural sciences. A proponent of 'common (...) sense' philosophy, he was particularly interested in the effect of successful rhetoric upon the mind. Published in two volumes, the work is divided into three books. Book 1 emphasises the necessity of acknowledging and adapting to the needs of an audience. In Book 2, Campbell expands on the linguistic tools a successful rhetorician should employ. Book 3 discusses the correct selection, number and arrangement of words required for successful argument. (shrink)

In the 21st century, Carl Gustav Jung (1875-1961) remains one of the key figures in the field of analytical psychology - and Psychological Types, or The Psychology of Individuation, published in 1921, is one of his most influential works. It was written during the decade after the publication of Psychology of the Unconscious (1912), which effectively ended his friendship and collaboration with Sigmund Freud. Whereas the earlier work had clearly marked Jung's psychoanalytical divergence from Freud it is the Psychology (...) of Types that fully clarifies and presents the nature, quality and characteristics of his analytical psychology. The work, which was in part a consequence of his need to reconcile the competing theories of Freud, whom he regarded as extraverted, and Alfred Adler, whom he saw as introverted, develops his concept of descriptive categories for understanding the human mind in terms of the two essential attitude types: introversion and extraversion. These basic attitudes operate in tandem with four principal interacting functions of consciousness which Jung identifies as sensation and intuition, which are functions of perception, and thinking and feeling, which are functions of judgment. The eight resulting psychological types are then explored, described, identified, characterised and explained in considerable detail, with a soaring range of examples drawn from the whole of human history, culture and experience. In his efforts to explore and illuminate the nature of the unconscious mind and indeed the collective unconscious, he investigates the problems posed by the differing psychological types and how these have manifested from classical and medieval times to the 20th century. His observations range from Aristotle, Socrates and Plato to Tertullian and Origen, and from Abélard and Master Eckhart to Martin Luther and the problem of transubstantiation. Jung takes the listener on an odyssey of human thinking. He considers the problem of types in the works of Schiller and Goethe, and Spitteler and his treatment of the Prometheus myth. He contrasts idealism and realism, the Apollonian and the Dionysian in Nietzsche, and explores a host of philosophical and religious sources from the Bible to Taoism to Brahminism. He considers the nature of the reconciling symbol in Spitteler before analysing the nature of types in modern philosophy, aesthetics and biography, giving detailed consideration to William James' characteristic pairs of opposites and Furneaux Jordan's 'character sketch of the emotional types'. Jung goes on to fully identify and describe the characteristic differences between the extraverted and introverted types and provides an extensive chapter on definitions to fully clarify the meaning of the language he employs and make his meaning more accessible. Authoritatively read by Martyn Swain for Ukemi Audiobooks, Psychological Types is an inexhaustible treasure chest of ideas and creative inspiration worth listening to time and time again. (shrink)

Motor learning is the process of updating motor commands in response to a trajectory error induced by a perturbation to the body or vision. The brain has a great capability to accelerate learning by increasing the sensitivity of the memory update to the perceived trajectory errors. Conventional theory suggests that the statistics of perturbations or the statistics of the experienced errors induced by the external perturbations determine the learning speeds. However, the potential effect of another type of error perception, a (...) self-generated error as a result of motor command updates, on the learning speeds has not been examined yet. In this study, we dissociated the two kinds of errors by controlling the perception of the aftereffect using a channel-force environment. One group experienced errors due to the aftereffect of the learning process, while the other did not. We found that the participants who perceived the aftereffect of the memory updates exhibited a significant decrease in error-sensitivity, whereas the participants who did not perceive the aftereffect did not show an increase or decrease in error-sensitivity. This suggests that the perception of the aftereffect of learning attenuated updating the motor commands from the perceived errors. Thus, both self-generated and externally induced errors may modulate learning speeds. (shrink)
