: In Cognitive penetrability and the epistemic role of perception Athanasios Raftopoulos provides a new defense of the thesis that, unlike early vision, late vision is cognitively penetrable, in accordance with a new definition of cognitive penetrability that is centered on the ideas of direct influence of cognition upon perception and of the epistemic role of perception. This new definition allows him to maintain that late vision is a genuinely perceptive stage of the perceptual (...) process. In this paper, I try to discuss not only whether this new definition has plausible consequences that allow only late vision to be cognitively penetrable but also whether the claim that late vision is genuinely perceptual allows it to have the kind of hybrid content, half nonconceptual and half conceptual, that Raftopoulos now wants to ascribe to it. Keywords: Cognitive Penetrability, weak, strong, and superstrong; Early and Late Vision; Nonconceptual Content Penetralibità cognitiva e visione secondaria Riassunto: In Cognitive penetrability and the epistemic role of perception Athanasios Raftopoulos dà una nuova difesa della tesi secondo cui, a differenza della visione primaria, la visione secondaria è penetrabile cognitivamente, secondo una nuova definizione della nozione di penetrabilità cognitiva centrata sulle idee di influenza diretta della cognizione sulla percezione e di ruolo epistemico della percezione. Questa nuova definizione gli consente di sostenere che la visione secondaria è una fase genuinamente percettiva del processo percettivo. Nell’articolo, provo a discutere non solo se la nuova definizione ha conseguenze plausibili che consentono solo alla visione secondaria di essere penetrabile cognitivamente, ma anche se l’idea che la visione secondaria sia genuinamente percettiva consente ad essa di avere il contenuto ibrido, in parte nonconcettuale e in parte concettuale, che Raftopoulos vuole ora ascriverle. Parole chiave: Penetrabilità cognitiva debole, forte e superforte; Visione primaria e secondaria; Contenuto nonconcettuale. (shrink)

: In this article I discuss Athanasios Raftopoulos’ view on the epistemic role of attention and early vision, as outlined in his most recent book. I start by examining his view on attention, which he illustrates during his discussion of structured cognitive contents and their interactions with perceptual contents, as well as during his discussion of selection effects. According to Raftopoulos, attention not only operates pre-perceptual input selection, but also influences perceptual processing during late vision biasing (...) the sampling of the iconic image for perceptual hypotheses-testing. Afterwards, I critically assess Raftopoulos’ conclusions about the epistemic role of early vision, which are based on his view about the role of attention. From this assessment, I raise a potential concern for his proposal in the form of a new problem of selection: the interesting epistemic consequences of cognitive penetrability either follow or do not follow from selection effects, depending on how these selection effects are construed, but regardless of the stage of visual processing in which they take place. Keywords: Cognitive Penetration; Attention; Constructivism; Selection Effects; Perceptual Epistemology Il ruolo epistemico della visione primaria: penetrazione cognitiva e selezione attentiva Riassunto: In questo articolo discuto la proposta di Athanasios Raftopoulos riguardo al ruolo epistemico dell’attenzione e della early vision, contenuta nella sua recente monografia. La mia discussione comincia da un esame delle sue idee riguardo all’attenzione, che illustra sia durante la sua discussione dei contenuti cognitivi strutturati e delle loro interazioni con i contenuti percettivi, sia durante la sua discussione degli effetti di selezione. Secondo Raftopoulos, l’attenzione non opera solamente una selezione pre-percettiva degli input, ma influenza anche i processi percettivi di late vision orientando il processo di valutazione delle ipotesi percettive sulla base dell’immagine iconica. Successivamente, valuto criticamente le conclusioni di Raftopoulos’ riguardo al ruolo epistemico di early vision, fondate sulla sua concezione del ruolo dell’attenzione. Da questo esame, evidenzio una potenziale criticità nella sua proposta costituita da un nuovo problema della selezione: le conseguenze epistemiche della penetrabilità cognitiva seguono o non seguono dai processi di selezione, a seconda di come tali effetti sono concepiti, ma indipendentemente dal livello nella serie dei processi visivi nel quale si verificano. Parole chiave: Penetrabilità cognitiva; Attenzione; Costruttivismo; Effetti di Selezione; Epistemologia percettiva. (shrink)

Cognitive and affective penetration of perception refers to the influence that higher mental states such as beliefs and emotions have on perceptual systems. Psychological and neuroscientific studies appear to show that these states modulate the visual system at the visuomotor, attentional, and late levels of processing. However, empirical evidence showing that similar consequences occur in early stages of visual processing seems to be scarce. In this paper, I argue that psychological evidence does not seem to be either sufficient (...) or necessary to argue in favour of or against the cognitive penetration of perception in either late or early vision. In order to do that we need to have recourse to brain imaging techniques. Thus, I introduce a neuroscientific study and argue that it seems to provide well-grounded evidence for the cognitive penetration of early vision in face perception. I also examine and reject alternative explanations to my conclusion. (shrink)

This book is about the interweaving between cognitive penetrability and the epistemic role of the two stages of perception, namely early and late vision, in justifying perceptual beliefs. It examines the impact of the epistemic role of perception in defining cognitive penetrability and the relation between the epistemic role of perceptual stages and the kinds of cognitive effects on perceptual processing. The book presents the argument that early vision is cognitively impenetrable because neither is it (...) affected directly by cognition, nor does cognition affect its epistemic role. It also argues that late vision, even though it is cognitively penetrated and, thus, affected by concepts, is still a perceptual state that does not involve any discursive inferences and does not belong to the space of reasons. Finally, an account is given as to how cognitive states with symbolic content could affect perceptual states with iconic, analog content, during late vision. (shrink)

The study examines the modes of representation and communication of information through illustrative teaching aids in the 19th century. It focuses primarily on the didactic wall paintings and the tradition of lectures with slides and notes, how could the experience of these types of collectively observed images influence impressions and expectations of early film audiences. Didactic images are here analyzed primarily in terms of their compositional features, but in an effort to explain how processuality penetrated into the didactic image (...) of the 19th century also with regard to the aspect of time. As a result, the study calls for a reassessment of the importance of the didactic wall painting in the formation of modern visuality and observational practices of the late 19th century. (shrink)

According to the cognitive penetrability hypothesis, our beliefs, desires, and possibly our emotions literally affect how we see the world. This book elucidates the nature of the cognitive penetrability and impenetrability hypotheses, assesses their plausibility, and explores their philosophical consequences. It connects the topic's multiple strands (the psychological findings, computationalist background, epistemological consequences of cognitive architecture, and recent philosophical developments) at a time when the outcome of many philosophical debates depends on knowing whether and how cognitive states can influence perception. (...) All sixteen chapters were written especially for the book. The first chapters provide methodological and conceptual clarification of the topic and give an account of the relations between penetrability, encapsulation, modularity, and cross-modal interactions in perception. Assessments of psychological and neuroscientific evidence for cognitive penetration are given by several chapters. Most of the contributions analyse the impact of cognitive penetrability and impenetrability on specific philosophical topics: high-level perceptual contents, the epistemological consequences of penetration, nonconceptual content, the phenomenology of late perception, metacognitive feelings, and action. The book includes a comprehensive introduction which explains the history of the debate, its key technical concepts (informational encapsulation, early and late vision, the perception-cognition distinction, hard-wired perceptual processing, perceptual learning, theory-ladenness), and the debate's relevance to current topics in the philosophy of mind and perception, epistemology, and philosophy of psychology.

How can we conceive of the relation between technologies of image-making and the formations of political power, without reducing the former to merely superstructural effects of a pre-existing ideology or deducing the latter from the functional determination inherent in technical apparatuses? In this article, I revisit the notion of the state as a visual form I proposed in an earlier work, arguing that in order to understand the articulation between politics and visuality in modernity we need to pay attention to (...) the performance of showing and seeing that mediates between the spectacle and spectatorship. To grasp the way in which historical change (political and technological) impacts on this constellation, in particular in the transition from photographic to cinematic regimes of visuality between the late 19th and early 20th century, I take these questions through two rather different ‘case studies’: photographer Juan Gutiérrez’s images of Brazilian state rituals in the mid-1890s and Jorge Luis Borges’s short story ‘The Aleph’ of 1949. Whereas Gutiérrez’s photographic series, I argue, announces the cinema and its ways of mobilizing actors and spectators alike, as the limit of a 19th-century visuality primed on the stability and self-enclosedness of viewers and objects, Borges’s story retrospectively enacts the transition from photographic to cinematic seeing in an intratextual battle of acts of transcription from the impossible object at the centre of the plot, which grants infinite, universal visibility to the one who beholds it. Reading the two together, or against one another, then, allows us to see the dimension of transience undercutting the apparent solidity and timelessness with which scopic regimes promise us access to the real.

Scholarship of the last half century has transformed approaches to paganism and Christianity in the late Roman world. Much as the paradigm of late antiquity has replaced traditional narratives of ‘decline and fall’, expounded systematically in the eighteenth century by Edward Gibbon, so recent scholarship has also challenged older narratives of pagan / Christian conflict, particularly heroic narratives of the resistance mounted by Rome’s ‘last pagans’. This article locates a crucial—although often neglected—prehistory and parallel to these debates in (...) the world of early modern humanist scholarship. It examines how fourth-century Roman pagan authors—especially Quintus Aurelius Symmachus and Ammianus Marcellinus—were read by printers, editors and philologists in the sixteenth and seventeenth centuries. In a world before Gibbonian decline and fall, humanist scholars navigated both religious conflicts and literary canon wars to articulate a robust vision of late antiquity avant la lettre, although for reasons very different from those which have motivated twentieth- and twenty-first-century revisionists. Even as some of their colleagues dismissed late pagan texts on the grounds of deficient Latinity or deficient Christianity (or both), the early modern scholars who embraced this expansive vision of the ancient canon ended up highlighting the ambiguities of late antique religion—especially the grey area between the ‘pagan’ and the ‘Christian’.

Empirical research suggests that motive states modulate perception affecting perceptual processing either directly, or indirectly through the modulation of spatial attention. The affective modulation of perception occurs at various latencies, some of which fall within late vision, that is, after 150 ms. poststimulus. Earlier effects enhance the C1 and P1 ERP components in early vision, the former enhancement being the result of direct emotive effects on perceptual processing, and the latter being the result of indirect effects (...) of emotional stimuli on perceptual processing that automatically capture exogenous attention. Other research suggests that emotional stimuli do not capture attention automatically but attentional capture is conditioned on the context. Since context dependent effects are first registered with the elicitation of N1 ERP component about 170 ms. poststimulus, emotional stimuli affect late vision. However, the early affective modulation of early vision by emotive states threatens the cognitive impenetrability of early vision since emotive states are associated with learning and past experiences. I argue that the emotive modulation of early vision does not entail the cognitive penetrability of early vision. First, the early indirect affective modulation of P1 is akin to the effects of spatial pre-cueing by non-emotive cues and these preparatory effects do not signify the cognitive impenetrability of early vision. Second, because the direct modulation of C1 signifies an initial, involuntary appraisal of threat in the incoming stimulus that precedes any cognitive states. (shrink)

Haptic object recognition is usually an efficient process although slower and less accurate than its visual counterpart. The early loss of vision imposes a greater reliance on haptic perception for recognition compared to the sighted. Therefore, we may expect that congenitally blind persons could recognize objects through touch more quickly and accurately than late blind or sighted people. However, the literature provided mixed results. Furthermore, most of the studies on haptic object recognition focused on performance, devoting little (...) attention to the exploration procedures that conducted to that performance. In this study, we used iCube, an instrumented cube recording its orientation in space as well as the location of the points of contact on its faces. Three groups of congenitally blind, late blind and age and gender-matched blindfolded sighted participants were asked to explore the cube faces where little pins were positioned in varying number. Participants were required to explore the cube twice, reporting whether the cube was the same or it differed in pins disposition. Results showed that recognition accuracy was not modulated by the level of visual ability. However, congenitally blind touched more cells simultaneously while exploring the faces and changed more the pattern of touched cells from one recording sample to the next than late blind and sighted. Furthermore, the number of simultaneously touched cells negatively correlated with exploration duration. These findings indicate that early blindness shapes haptic exploration of objects that can be held in hands. (shrink)

The Whorfian hypothesis has received support from recent findings in psychology, linguistics, and anthropology. This evidence has been interpreted as supporting the view that language modulates all stages of perception and cognition, in accordance with Whorf’s original proposal. In light of a much broader body of evidence on time perception, I propose to evaluate these findings with respect to their scope. When assessed collectively, the entire body of evidence on time perception shows that the Whorfian hypothesis has a limited scope (...) and that it does not affect early stages of time perception. In particular, all the available evidence shows that the scope of language modulation is limited in the case of time perception, and that the most important mechanisms for time perception are cognitive clocks and simultaneity windows, which we use to perceive the temporal properties of events. Language modulation has distorting effects, but only at later stages of processing or with respect to specific categorization tasks. The paper explains what is the role of these effects in the context of all the available evidence on time cognition and perception. (shrink)

This article explores the diversity of the European idea of peace in the late thirteenth and early fourteenth centuries. In the late Middle Ages, a literary genre of “peace writings” emerged. Despite the ubiquitous academic interest in peace, however, late medieval scholastic conceptions of peace have hitherto escaped serious scholarly investigation. Drawing on Johan Galtung's classic typology of the idea of peace, this essay offers an examination of the discussions of Thomas Aquinas, Remigio de’ Girolami, and (...) Dante on peace, which not only illustrates the diversity of late medieval visions of peace but also argues that late medieval thinkers shared the recognition that temporal peace was possible: a significant departure from the Christian skepticism of this-worldly peace.

In a spellbinding narrative that skillfully weaves together cutting-edge research among today's foremost scientists, theoretical physicist Michio Kaku--author of the bestselling book Hyperspace --presents a bold, exhilarating adventure into the science of tomorrow. In Visions, Dr. Kaku examines in vivid detail how the three scientific revolutions that profoundly reshaped the twentieth century--the quantum, biogenetic, and computer revolutions--will transform the way we live in the twenty-first century. The fundamental elements of matter and life--the particles of the atom and the nucleus of (...) the cell--have now been decoded, closing one of the great chapters of scientific history. But this is just the preface to an even more far-reaching scientific revolution, as we make the transition from being passive observers of the mysteries of nature to becoming masters of nature, able to manipulate matter, life, and intelligence to remold the world around us. In the first part of Visions, Dr. Kaku discusses the cyber future, when millions of microprocessors are scattered throughout our environment; when the iron principle that has ruled the computer industry, Moore's Law, finally collapses, forcing scientists to adopt startling new designs like DNA computers and quantum computers; and when artificial intelligence systems finally arrive. In the next section, Dr. Kaku shows how the decoding of DNA will allow us to conquer devastating genetic diseases, defeat many cancers at the molecular level, synthesize new medicines using virtual reality, grow new organs, conquer aging and reshape our genetic inheritance. Finally, he explores how quantum physicists will perfect new ways to harness the cosmic energy of the universe--from molecular machines to supermagnets that may energize a second industrial revolution, to powerful fusion engines that one day may take us to the stars. What makes Michio Kaku's vision of the future of science so compelling and authoritative is that it is based on the groundbreaking research already underway at leading laboratories around the world. Weaving interviews with over 150 scientists--several of them Nobel laureates--into a rich, inspiring narrative, Dr. Kaku reveals the growing consensus among key scientists about how science will likely evolve through the early, middle, and late years of the twenty-first century. An intimate, thrilling tour through the next century of science, Visions is a riveting, essential map to how scientists will reshape our future. (shrink)

In Kingdom and Glory, Agamben analyzed the dual perspective of the void, through the metaphor of the empty throne, in the governmental machine in the West. I engage with the ambiguous question of the void with regard to the concept of sovereignty through my reading of two Chinese intellectuals in the late Qing period, Liang Qichao (1872–1929) and Zhang Taiyan (1869–1936). This paper therefore addresses the question of sovereignty and the void in the discourse of nation in early (...) modern China, an issue that is related to the problem of the political economy or the politics of life. I argue that the rhetorical move in Liang Qichao’s argument for the birth of a new nation and new people was to move from the not-having (無) to the there is (有) in support of the formation of a new nation-state and a restricted logic of sovereignty, while Zhan Taiyan’s position was to affirm the dynamitic re-composition of the void by constantly negating the given fixated state, and thus proposing a different and radical vision of nation and full sovereignty of the lives of each and every one of the people who are co-inhabiting in the polis.

Western literary, philosophical, and religious traditions from Plato and Paul to Augustine and Avicenna have utilized, exploited, or been subjected to allegorical interpretation. Naturally developing a composite picture of interpretive allegory from such a large landscape faces numerous difficulties.

Pylyshyn restricts cognitively penetrable vision to late vision, whereas he does not make any distinction between different kinds of penetrating cognition. I argue that this approach disconnects early vision content from late vision content and blurs the distinction between the latter and the content of thought. To overcome this problem I suggest that we should not distinguish between different kinds of visual content but instead introduce a restriction on the kind of cognition that (...) can directly penetrate visual experience. In particular, I suggest that visual experience, unlike thought, is directly penetrated only by practical non-propositional knowledge. I specify this weak cognitive penetrability in anti-representational terms. In particular, I suggest that the dependence of visual content on practical non-propositional knowledge should be conceived as a rational non-inferential relation, for it is in this way that we can account for the distinctive content of visual experience.

An early proponent of the social sciences, Frédéric Le Play, was the occupant of senior positions within the French state in the mid- to late 19th century. He was writing at a time when science was ascending. There was for him no doubt that scientific observation, correctly applied, would allow him unmediated access to the truth. It is significant that Le Play was the organizer of a number of universal expositions because these expositions were used as vehicles to (...) demonstrate the ascendant position of western civilization. The fabrication of linear time is a history of progress requiring a vision of history analogous to the view offered the spectator at a diorama. Le Play employed the design principles and spirit of the diorama in his formulations for the social sciences, and L’Exposition Universelle of 1867 used the technology wherever it could. Both the gaze of the spectators and the objects viewed are part and products of the same particular and unique historical formation. Ideas of perception cannot be separated out from the conditions that make them possible. Vision and its effects are inseparable from the observing subject who is both a product of a particular historical moment and the site of certain practices. (shrink)

_Messiahs and Machiavellians_ is an innovative exploration of “modern evil” in works of early- and late-modern theatre, raising issues about ethics, politics, religion, and aesthetics that speak to our present condition. Paul Corey examines how theatre—which expressed a key political dynamic both in the Renaissance and the twentieth century—lays open the impulses that instigated modernity and, ultimately, unparalleled levels of violence and destruction. Starting with Albert Camus’ _Caligula_ and Samuel Beckett’s _Waiting for Godot_, then turning to Machiavelli’s _Mandragola_ (...) and Shakespeare’s _Measure for Measure_, Corey traces the emergence of two dominant, intertwining features of modern evil: an unrestrained pursuit of power and the utopian desire for perfection. Corey’s imaginative and convincing readings of these plays, based on detailed textual analysis, move beyond the accounts usually offered by literary critics. Drawing on political, theological, and philosophical sources—a combination as fertile as it is unusual—Corey’s methodology allows him to make keen and subtle arguments about the eschatological nature of modern politics. “Corey’s lucid, compelling treatise argues for a radical reconsideration of the role of tragedy in dealing with the shifting metaphysical and metatheatrical sands of the contemporary era. While the study begins with an examination of mid-20th Century French existentialism—and the dramatic work of Beckett and Camus in particular—the book soon takes the reader on a fascinating voyage back into the ‘problem’ comedies of the Italian and English Renaissance theatre, and beyond that, into Greek tragedy to understand the evolving concept of ‘evil’ in the Western philosophical, theological, and dramatic tradition. Ending with a reflection on the new ‘theatre’ of terrorism entering the 21st Century, Corey poses the intriguing suggestion, that far from being irrelevant to the post-modern era, a ‘new tragic sensibility’ may become key to our gaining a ‘lucid awareness of our current situation […] the limits of politics, the indelible nature of violence, our inescapable mortality, and a need for prudence’ ” —_Moira Day, University of Saskatchewan_ “A sensitive examination of the problem of evil in Renaissance and 20th century drama.

Nichols, Baylor University_ _ _ “In _Messiahs and Machiavellians_, Paul Corey delivers insights both numerous and profound.

By comparing two time periods, the early and late 20th century, this article examines the ambiguities and ambivalences in the state promotion of women in the nation-building projects of Mexico. I argue that in both cases, the state was keen to promote itself as modern and progressive and used women's status in society to these ends. Despite the explicit focus on women, there were many ambiguities and ambivalences resulting from the competing state projects in the political, socio-economic and (...) cultural arenas offering women both privileged spaces and constraints in the development of gendered citizenship. The contradictions arise from simultaneously promoting women's rights, extolling traditional gender roles and fearing women's political activism – both conservative and more radical. Although these ambivalences and ambiguities remain a constant feature, there is a key difference in the two time periods: in one the regime is inward looking, economically protectionist and corporatist, while in the other a new vision of Mexico has attempted to dismantle the corporatist structures and state development project with private economic initiatives and political individualism. In both periods, women gained important rights but romanticized imagery of the self-sacrificing mother was mobilized to underpin change: women were expected both to change and remain the same.

This volume considers contingency as a historical category resulting from the combination of various intellectual elements – epistemological, philosophical, material, as well as theological and, broadly speaking, intellectual. With contributions ranging from fields as diverse as the histories of physics, astronomy, astrology, medicine, mechanics, physiology, and natural philosophy, it explores the transformation of the notion of contingency across the late-medieval, Renaissance, and the early modern period. Underpinned by a necessitated vision of nature, seventeenth century mechanism widely identified (...) apparent natural irregularities with the epistemological limits of a certain explanatory framework. However, this picture was preceded by, and in fact emerged from, a widespread characterization of contingency as an ontological trait of nature, typical of late-Scholastic and Renaissance science. On these bases, this volume shows how epistemological categories, which are preconditions of knowledge as “historically-situated a priori” and, seemingly, self-evident, are ultimately rooted in time. Contingency is intrinsic to scientific practice. Whether observing the behaviour of a photon, diagnosing a patient, or calculating the orbit of a distant planet, scientists face the unavoidable challenge of dealing with data that differ from their models and expectations. However, epistemological categories are not fixed in time. Indeed, there is something fundamentally different in the way an Aristotelian natural philosopher defined a wonder or a “monstrous” birth as “contingent”, a modern scientist defines the unexpected result of an experiment, and a quantum physicist the behavior of a photon. Although to each inquirer these instances appeared self-evidently contingent, each also employs the concept differently. (shrink)

The year 2022 marks a century since the death of Reverend John Knox Bokwe, a minister of the United Free Church of Scotland Mission in South Africa. Although little known, Bokwe was an important member of the emerging African intellectual elite towards the end of the 19th century. He demonstrated the creative tension that arises when two cultures encounter each other as he confronted and made sense of the historical meaning of modernity. He emphasised the value of his traditional culture (...) in a context where western culture was making a significant transforming impact on African life, which produced a creative tension throughout his working life in various contexts. This paper analyses his particular contribution as an active committed Christian through a number of overlapping lenses – his life in clerical work, journalism, literature, theology, education, music and his involvement in social and political issues and ministry. In all this he operated with a holistic vision. The paper offers an assessment of his life’s work using a combination of primary and secondary sources. Contribution: This article adds to the growing body of work that is derived from studies on the emergence of indigenous leadership in South Africa by looking at the life, work and Christian witness of Rev John Knox Bokwe from the perspective of the creative tension that he experienced and navigated in the varied professional and vocational perspectives he engaged in during his life.

This article assesses Frank I. Michelman’s constitution-centered and proceduralist interpretation of Rawls’ conception of political legitimacy and argues that it merits attention because it highlights the institutional aspects of Rawls’ understanding of political legitimacy for constitutional democracies. However, the article also questions Michelman’s interpretation of Rawls’ ‘liberal principle of legitimacy’ (LPL) and the later ‘idea of political legitimacy based on the criterion of reciprocity’ (ILBR). As Michelman rightly points out, for the exercise of political power to be legitimate in a (...) constitutional democracy, it must be in accordance with a constitution that is itself legitimate or reasonably acceptable to free and equal citizens. Yet, the article argues that Rawls’ two legitimacy formulations are attempts to make an additional point: Namely that when democratic citizens exercise political power in ‘the fundamental political issues’, or in issues that shape the basic justice of society or the essentials of the constitution itself, they must respect the ideal of public reason – or ensure themselves and other citizens that their exercise of political power is in accordance with the underlying basic political-moral ideas of persons and society that make the constitution itself acceptable to them. The LPL and the ILBR are conceptions of political legitimacy, not in the sense of setting up a criterion for when a specific law is legitimate, but in the sense of outlining civic or “office-specific” constraints that citizens and public officials must put on their reasoning and exercise of political power in the fundamental political issues for the practice of a constitutional democracy to be legitimate, or well-ordered, reasonably just, and stable for the right reasons – in the long run. The article also discusses why Rawls saw the need to reformulate the LPL, and how the later ILBR assigns a new significance to citizens’ actual use of public reason and their intersubjective deliberation.

This volume is an important re-evaluation of space and spatiality in the late Renaissance and early modern period. History of science has generally reduced sixteenth and seventeenth century space to a few canonical forms. This volume gives a much needed antidote. The contributing chapters examine the period’s staggering richness of spatiality: the geometrical, geographical, perceptual and elemental conceptualizations of space that abounded. The goal is to begin to reconstruct the amalgam of “spaces” which co-existed and cross-fertilized in the (...) period’s many disciplines and visions of nature. Our volume will be a valuable resource for historians of science, philosophy and art, and for cultural and literary theorists. (shrink)

Postural instability and balance impairment are disabling symptoms in patients with acute unilateral peripheral vestibular hypofunction. Vestibular rehabilitation is known to improve the vestibular compensation process, but its effect on posture recovery remains poorly understood, little is known about when VR must be done, and whether the degree of vestibular loss matters is uncertain. We analyzed posture control under static and dynamic postural tasks performed in different visual conditions [eye open ; eyes closed ; and optokinetic stimulation] using dynamic posturography. (...) Non-linear analyses of the postural performance were performed in two groups of patients with UVH subjected to the same VR program based on the unidirectional rotation paradigm and performed either early or later after vertigo attack. Distribution of the angular horizontal vestibulo-ocular reflex gain values recorded on the hypofunction side before rehabilitation differentiated two distinct sub-groups with aVOR gains below or above 0.20. The postural performance of the four sub-groups of patients with UVH tested before VR showed significantly altered postural parameters compared with healthy controls. Greater instability, higher energy to control posture, larger sway without feedback corrections, and lower time of automatic control of posture were observed in static conditions. The four sub-groups recovered near-normal postural performance after VR in the EO and EC conditions, but still exhibited altered postural performance with optokinetic stimulation. In dynamic posturography conditions and before VR, the percentage of patients able to perform the postural tasks with EC and optokinetic stimulation was significantly lower in the two sub-groups with aVOR gain <0.20. After VR, the improvement of the postural parameters depended on the stage of rehabilitation and the degree of vestibular hypofunction. The best balance function recovery was found in the sub-group with early VR and pre-rehabilitation aVOR gain above 0.20, the worst in the sub-group with late rehabilitation and aVOR gain below 0.20. These differences were seen when the vestibular input remains the main sensory cue to control balance, that is, on unstable support without vision or altered visual motion cues. These findings extend to dynamic balance recovery the crucial roles of early rehabilitation and degree of vestibular hypofunction which we have already highlighted for vestibulo-ocular reflex recovery.

The transition away from the highly intolerant and persecutory regimes of late-medieval and early-modern Europe was facilitated by four important developments. First, Europeans learned that social order and cohesion are threatened less by diversity than by intolerance of it. Second, the traditionally paternalist vision of the state’s role was called into question by a new valuation of the individual conscience and consequently of individual liberties. Third, the assumption that the meaning of symbols is objectively determined was replaced (...) by the recognition that symbols are intersubjectively determined by convention. Fourth, Europeans began to distinguish two senses of publicity: visibility and representativeness. The tenacious hold of these four assumptions is illustrated by laws of laïcité, which harken back to the medieval mindset on all four counts. (shrink)

Democratic political theory often sees collective action as the basis for non-coercive social change, assuming that its terms and practices are always self-evident and accessible. But what if we find ourselves in situations where collective action is not immediately available, or even widely intelligible? This book examines one of the most intellectually substantive and influential Chinese thinkers of the early twentieth century, Zhang Shizhao, who insisted that it is individuals who must 'make the political' before social movements or self-aware (...) political communities have materialized. Zhang draws from British liberalism, democratic theory, and late-Imperial Confucianism to formulate new roles for effective individual action on personal, social, and institutional registers. In the process, he offers a vision of community that turns not on spontaneous consent or convergence on a shared goal, but on ongoing acts of exemplariness that inaugurate new, unpredictable contexts for effective personal action.

This volume is an important re-evaluation of space and spatiality in the late Renaissance and early modern period. History of science has generally reduced sixteenth and seventeenth century space to a few canonical forms. This volume gives a much needed antidote. The contributing chapters examine the period’s staggering richness of spatiality: the geometrical, geographical, perceptual and elemental conceptualizations of space that abounded. The goal is to begin to reconstruct the amalgam of “spaces” which co-existed and cross-fertilized in the (...) period’s many disciplines and visions of nature. Our volume will be a valuable resource for historians of science, philosophy and art, and for cultural and literary theorists. (shrink)

Entre los estudios críticos que existen en torno a la obra de Paul Feyerabend predominan aquellos que subrayan una discontinuidad radical entre la versión temprana y tardía de su pensamiento. Todo ello contribuye a que dispongamos de una visión fragmentada e incompleta de un pensador que evoluciono hasta el 1994, año de su fallecimiento. Nuestro propósito es ofrecer una explicación de su itinerario intelectual de tal modo que quedé patente su continuidad en la clave de sus críticas contra los falsos (...) absolutos erigidos por el positivismo lógico y el racionalismo científico. Mostraremos las diversas cuestiones que Feyerabend aborda en las distintas épocas de su vida pero, al mismo tiempo, subrayaremos la unidad o coherencia lógica que existe en su revisión crítica de la racionalidad científica. Nos preocuparemos por entender las razones por las cuales nuestro filósofo de la ciencia va trasladando sus distintos focos de discusión o crítica. A common element in studies of Paul Karl Feyerabend is the distinction between five periods in his work. John Preston sees a radical discontinuity between the early and late versions of Feyerabend’s thought. All of this contributes our having a fragmented and incomplete view of a thinker who continued to evolve until 1994, the year of his death. We aim to provide an explanation of his intellectual journey that shows the evident continuity and unity of his thought. We will discuss the various issues he addressed in the different periods of his life, but at the same time we will emphasize the unity or logical coherence among them. Our aim is to understand the reasons why the philosopher of science changed his distinct foci of discussion and criticism. (shrink)

This is the story of the transformation of the ways in which the increasingly Christianized elites of the late antique Mediterranean experienced and conceptualized linguistic differences. The metaphor of Babel stands for the magnificent edifice of classical culture that was about to reach the sky, but remained self-sufficient and selfcontained in its virtual monolingualism - the paradigm within which even Latin was occasionally considered just a dialect of Greek. The gradual erosion of this vision is the slow fall (...) of Babel that took place in the hearts and minds of a good number of early Christian writers and intellectuals who represented various languages and literary traditions. This step-by-step process included the discovery and internalization of the existence of multiple other languages in the world, as well as subsequent attempts to incorporate their speakers meaningfully into the holistic and distinctly Christian picture of the universe.

There is a very deep tension that exists at the heart of Aristotle’s metaphysical system in virtue of the fact that his works seem to contain two distinct and not obviously commensurate ontologies: an early ontology that Aristotle outlines in the Categories and a later ontology that he develops in his physical–metaphysical treatises. In this paper I briefly describe the two ontologies, discuss the sources of conflict and outline different scholarly speculations about the relationship between the two.

There are inconsistencies in Dōgen's writing over his career, especially between the twelve-fascicle and the seventy-five-fascicle Shōbōgenzō. The nature of the twelve-fascicle edition, the hermeneutic of interpreting Dōgen's kōan style of writing, and the problems in relating the twelve-fascicle edition to the earlier kōan style of the seventy-five-fascicle edition are examined.

Hung Yao-hsün is one of the most creative, albeit long overlooked, thinkers in Japanese-ruled Taiwan. This paper’s aim is threefold. It first argues that while Hung’s early philosophy was rooted in the Kyoto school, he is a key founder of the Sit-chûn movement of Taiwanese philosophy. It next shows that during Taiwan’s martial law, Hung’s thought features a “Buddhist turn,” in which Zen is incorporated within existentialism. Third, while this turn is a sharp contrast to his prewar philosophical activism, (...) Hung’s last work stressed Abraham Kaplan’s view that philosophy should be connected to one’s life experience, echoing Hung’s prewar usage of fūdo in justifying Taiwan’s cultural subjectivity. In other words, there is an implicit continuity between his early and late philosophy. (shrink)
