This article reports an interesting link between the psychophysical property of intentional control of perceptual switching and the underlying neural activities. First, we revealed that the timing of perceptual switching for a dynamical dot quartet can be controlled by the observers' intention, without eye movement. However, there is a clear limitation to this control, such that each animation frame of the stimulus must be presented for a sufficiently long time length; in other words, the frequency of the stimulus alternation must (...) be sufficiently slow for the control. The typical stimulus onset asynchrony for a 50% level of success was about 275 ms for an average of 10 observers. On the basis of psychophysical property, we designed three experiments for investigating the neural process with a magnetoencephalography. They revealed that: (1) a peak component occurring about 300 ms after a reversal was stronger when the direction of perceived motion was switched intentionally than when it was not switched, and (2) neural components about 30–40 ms and 240–250 ms after the reversal of the stimulus animation were stronger when perception was altered intentionally than when it was switched unintentionally. The 300 ms component is consistent with a previous study about passive perceptual switching (Struber and Herrmann [2002]: Cogn Brain Res 14:370–382), but the intentional effect was seemed to be a different component from the well-known P300 component.

Neuronal activities have recently been reported to exhibit power-law scaling behavior. However, it has not been demonstrated that the power-law component can play an important role in human perceptual functions. Here, we demonstrate that the power spectrum of magnetoencephalograph recordings of brain activity varies in coordination with perception of subthreshold visual stimuli. We observed that perceptual performance could be better explained by modulation of the power-law component than by modulation of the peak power in particular narrow frequency ranges. The results (...) suggest that the brain operates in a state of self-organized criticality, modulating the power spectral exponent of its activity to optimize its internal state for response to external stimuli.

The point of departure of this paper is the striking similarities between the dispositions critical media literacy education aims to cultivate and the characteristics conspiracy theorists claim to embody. The golden question of critical literacy, “who benefits?” is in fact the central question of conspiracy theorists: “cui bono?” While critical media literacy educators teach learners to disrupt the common sense, to interrogate multiple viewpoints, to focus on sociopolitical issues, and to take actions and promote social justice, conspiracy theorists claim that (...) they do exactly those things. What I wish to illuminate through this juxtaposition, however, is not a way to clearly demarcate “critical” from “conspiratorial” theorizing, but is a question of educational desirability of skepticism. Skepticism in this paper is not understood as a classical epistemological question of the possibility of knowledge attainment, but as a form of vigilance toward epistemic authorities like the government, media, and academic institutions. Drawing on philosophy of conspiracy theories and political epistemology, I illuminate the problem of radical skepticism that characterizes some conspiracy theories and discuss the pivotal epistemic role of trust. Through this, I claim that critical media literacy education for democratic citizenship must strike a balance between cultivation of skepticism and building of trust toward epistemic authorities.

TOPOLOGIE DES LOGOS UND KANT-INTERPRET A TION § I. Topologie des Logos Die Geschichte der Philosophie ist die Geschichte der Entwicklung des Logos. Jedes System der Philosophie hat seinen Logos. Jedes System der Philosophie, welches seinen Logos hat, ist vom Standpunkte der Entwicklung der Philosophie als Ganzem gesehen eine notwendige Entwicklung des Logos. Die Geschichte der Philosophie ist, wie Hegel sagte, eine Entwicklung des absoluten Geistes. Aber diese Entwicklung des Logos soll man nicht als dialektische Entwicklung, wie Hegel sie sah, (...) bezeichnen. Vielmehr befindet sich das System der Hegelschen Philosophie selber an einer besonderen Stelle der Entwicklung des Logos. Die Entwicklung des Logos ist nicht immer dialektisch-formelle Entwicklung und wird nicht in Dialektik bis zum Äußersten getrieben. Wir müssen uns davor hüten, die Entwicklung des Logos formell dialek tisch zu sehen. Vielmehr müssen wir die Entwicklung des Logos - in der Phase der notwendigen Entwicklung, in der er sich befinde- positiv betrachten. Dialektische Konstruktion der Geschichte der Philosophie auf Kosten der Tatsachen, wie Hegel sie trieb, ist dogma tisch-idealitisches Verhalten, und unser Verhalten soll nicht solches sein. Betrachten wir positiv die Entwicklung des Logos in der Geschich te der Philosophie, so entsteht nicht dialektische Geschichtsauffassung, sondern Topologie der Entwicklung des Logos: kurz, die Topologie des Logo::. Nach der Topologie des Logos wird jedem System der Philoso phie sein Topos in der Entwicklung des Logos als Ganzem gegeben. (shrink)

This book constitutes the thoroughly refereed joint post-proceedings of three international workshops organized by the Japanese Society for Artificial Intelligence, held in Tokyo, Japan in June 2006 during the 20th Annual Conference JSAI 2006. The volume starts with eight award winning papers of the JSAI 2006 main conference that are presented along with the 21 revised full workshop papers, carefully reviewed and selected for inclusion in the volume.

The aim of this paper is to propose an antithesis to the overreliance on scientific facts and objectivity to counter mis- and disinformation in media literacy education. Through conceptual examination of meaning, care, and facts, I demonstrate the ontological priority of meaning and values in the life-world. I then discuss conspiracy theories as a textual genre in which the crisis of meaning manifests as a prominent factor. Given the centrality of meaning, I claim that literacy education needs to go beyond (...) the matters of fact and address matters of concern in this supposedly post-truth world. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Religion and Science: Nishitani’s View of Nihility and Emptiness–A Pure Land Buddhist CritiqueRyusei TakedaIn general, philosophical critique of Nishida, Tanabe, and Nishitani, the so-called Kyoto school, has been mainly conducted from a Zen Buddhist perspective. One should not, however, overlook the fact that a profound regard for the philosophical aspects of Pure Land Buddhist thought, another major stream of Mahayana Buddhism, is deeply intertwined in the foundation of their (...) philosophies. But the ways in which they interpret it and the position they give it within their philosophical systems are not the same: they have taken different forms, often giving rise to original terminology, in accord with each thinker’s metaphysical speculation.As Alfred N. Whitehead critically argues in his Religion in the Making, the fundamental reason for the decay of both Buddhism and Christianity is that “each religion has unduly sheltered itself from the other. The self-sufficient pedantry of learning and the confidence of ignorant zealots have combined to shut up each religion in its own forms of thought. Instead of looking to each other for deeper meanings, they have remained self-satisfied and unfertilized.” Further, “both have suffered from the rise of the third tradition, which is science, because neither of them had retained the requisite flexibility of adaptation.” 1In this contemporary situation, the philosophies of Nishida, Tanabe, and Nishitani, in which the issue of religion and science has been brought into fundamental question and examined on the dimension of origin of their development, have extremely important implications for the critical interpretation of Pure Land Buddhist doctrines, particularly in the postmodern world. 2There are two points I want to make in this paper. First, the fundamental structure of Pure Land Buddhism, in a way an antipode to Zen, will be examined in light of Nishitani’s metaphysical analysis of the relationship between human experience and the laws of nature, particularly bringing into focus his existential realization of ‘nihility.’And second, I want to challenge Nishitani’s understanding of ‘emptiness’ from my perspective as a Pure Land Buddhist, and also to uncover some fundamental [End Page 155] problems underlying his view of ‘emptiness’ by attempting to relate it to Nagarjuna’s negation of ‘substance’ in his concept of ‘non-self being,’ or ‘nih-svabhava.’ 3What is Religion for Nishida, Tanabe, and Nishitani?Before getting into those two topics, I want to make a rough sketch indicating about where Nishida, Tanabe, and Nishitani see that religious experience is to be truly realized.The starting point of Nishida’s understanding of religion is found in his argument that “it is on the ground of fact that religion ought to be considered.” The fact of religious experience is in his view none other than self-awareness of ‘absolute nothingness,’ which is also the foundation of what we consider as objective knowledge. The self-awareness manifests itself in the midst of such fact and serves to reveal that fact. He argues that the ultimate goal of Mahayana Buddhism is to penetrate into the depth of this fact.In Tanabe’s philosophy, one’s resurrection and return to the world (genso) and self-renunciation through ‘metanoetics’ (zangedo), a philosophy of absolute Other-power, are required and witnessed to in order for one to establish a genuine religious standpoint. Neither/nor, instead of both/and, is the only relationship in which the self negates itself by means of contradiction, so that at the same time as the self is extinguished in the negation, the contradiction of that which opposes the self is also extinguished. Converted into the neither/nor relationship, both self and contradiction cease to be contradictory opposites. 4 This is Tanabe’s criticism directed at Nishida’s notion of the self-identity of absolute contradiction. Nothingness can never be intuited as such self-identity. The self-consciousness of nothingness is only in resurrection and return to the world, which is witnessed to through practice based upon faith and performed in obedience to Other-power. 5For Nishitani the question of the essence of religion must be answered through tracing the process of the genuine pursuit of true reality. He attempts to interpret the religious quest... (shrink)
