Cortical stimulation has been used for brain mapping for over a century, and a standard assumption is that stimulation interferes with task execution due to local effects at the stimulation site. Stimulation can however produce afterdischarges which interfere with functional localization and can lead to unwanted seizures. We previously showed that cognitive effort can terminate these afterdischarges, when termination thus occurs, there are electrocorticography changes throughout the cortex, not just at sites with afterdischarges or sites thought functionally important for the (...) cognitive task used, and thresholds for afterdischarges and functional responses can change among stimulation trials. We here show that afterdischarge termination can occur prior to overt performance of the cognitive tasks used to terminate them. These findings, taken together, demonstrate that task-related brain changes are not limited to one or a group of functional regions or a specific network, and not limited to the time directly surrounding overt task execution. Discrete locations, networks and times importantly underpin clinical behaviors. However, brain activity that is diffuse in location and extended in time also affect task execution and can affect brain mapping. This may in part reflect fluctuating levels of attention, engagement, or motivation during testing. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Reconfiguring Modernity: Concepts of Nature in Japanese Political IdeologyWilliam R. LaFleurReconfiguring Modernity: Concepts of Nature in Japanese Political Ideology. By Julia Adeney Thomas. Berkeley, Los Angeles, and London: University of California Press, 2001. Pp. xvi + 225.Books written by persons who self-identify as intellectual historians usually lend themselves more easily to review in history journals than in those that focus on philosophy. Reconfiguring Modernity: Concepts of Nature in (...) Japanese Political Ideology, Julia Adeney Thomas' study of certain Meiji period thinkers is such a book. In 2002 it was awarded the John K. Fairbank Prize in history. Taking a cue to step into her topic from an early essay by Robert Bellah, one in which he had written that "the concern for nature has been a pervasive one in much of modern Japanese thought,"1 Thomas specifies her own search: "It is now time to recover the historical mutability of that concept, and to describe precisely its politics at particular moments in Japan's confrontation with modernity, both within the dominant ideology of the moment and with the alternatives to it" (pp. 30-31).Thomas is among those American students of Japan apparently trained to challenge the massive amounts of excavational scholarship and mile-high reputations of Japanese scholars of Japan. She picks arguments with some of the most highly respected Japanese minds of the twentieth century: the late Maruyama Masao, the late Ienaga Saburō, and Matsumoto Sannosuke.Although Thomas' criticisms tend to focus on those portions of the works of these prolific scholars that have been translated into English,2 some of her criticisms are certainly interesting and possibly valid. For instance, Maruyama, "who repeatedly excoriated Japan's reliance on the political authority of nature (shizen) " (p. 16), envisioned modernity, surely desirable, as involving a move "against Chu Hsi Confucianism"—that is, "an inevitable turning away from nature (shizen) to invention (sakui)" (p. 17). Nevertheless, Maruyama's hero, Ogyū Sorai (1666-1728), had understood "the narrative of modernity" but, tragically, stepped "back from invention at the critical moment, unable, it would seem, to embrace it as the culmination of the historical process" (p. 19).Thomas, rightly I think, indicates that most left and liberal thinkers in Europe and America in the early and mid-twentieth century were skeptical of an invocation of the "natural" in the making of political theory.3 However, she stakes a claim to being part of a different generation, one that rejects the old binary opposition between nature and culture—as well as the further assumption that Western political thinking had successfully disengaged itself from invoking the category of what is natural. Taking a cue from Stephen Toulmin's demonstration of how many of Europe's modernizers embraced and used, rather than rejected, concepts of nature,4 Thomas claims that, at least for us who now live "'on the far side of modernity,' nature can be seen [End Page 172] as multivalent rather than the antonym in a series of binary opposites." In practice this means that for us now, "nature can no longer appear synonymous with the anti-modern, the past, the oppressive, or the Orient" (p. 25).I ask that the reader highlight the sentences above. They constitute what in my view is the most important and by far the most interesting move made in Refiguring Modernity. I will return to them below. First, however, I will recapitulate the progression of the book's chapters. They move in the pattern of linear history. The first, discussed already and titled "The Trouble with Nature," introduces the problem. The second, "The Topographical Imagination of Tokugawa Politics," deals with thinkers of the Tokugawa (Edo) period (1600-1868). Theirs was an era during which, although Chinese claims to being both topographically and morally central had long been dutifully accepted in Japan, strong-thinking Japanese argued that China's frequent dynastic changes demonstrated that "centralness need not be possessed physically to be enacted morally" (p. 42). By outdoing contemporaneous Chinese in terms of being Confucian, Neo-Confucian, or whatever it was that had its origins in China, Japanese and in some sense Japan as a whole were imagined to be the "real China."5...

This essay presents a contextualist defense of the role of narrative and metaphor in the articulation of environmental ethical theories. Both the intelligibility and persuasiveness of ecocentric concepts and arguments presuppose that proponents of these ideas can connect with the narratives and metaphors guiding the expectations and interpretations of their audiences. Too often objectivist presuppositions prevent the full contextualization of environmental ethical arguments. The result is a disembodied environmental discourse with diminished influence on citizens and policy makers. This essay is (...) a pragmatist call for more philosophical attention to locating speakers, audiences, and meanings in more intelligible "discursive spaces." © 1999 Elsevier Science Inc. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:R. D. Ackerman BELIEVING IN A FICTION: WALLACE STEVENS AT THE LIMITS OF PHENOMENOLOGY The "ring of men" of "Sunday Morning" will chant their "devotion to the sun, / Not as a god, but as a god might be, / Naked among them, like a savage source" (CP, pp. 69-70).' Solar nakedness is deferred even as it is named. The problem for belief is the question of appearance and (...) representation. Things appear as and like.... The phenomenological return to things is also a turn to fiction, as Husserl understood: "If anyone loves a paradox, he can really say... that the element which makes up the life of phenomenology... is fiction. ' " The sun is divine, and it is not; it is both naked and clothed, savage and civilized, source (or end) and means. But such paradox is ultimately unsatisfying, and as we will see with Stevens, the need for belief—for an image or idea of totality—forces the issue of fiction and reality. The Stevens we will have in view is not the Stevens—as if there were such a creature. Our Stevens is the one most persuaded by promises such as those of phenomenology, the one most concerned with decreation (reduction) and fresh beginnings, with discovery and recognition, with imagination, the body, and the earth. This is the Stevens for whom the barrier of language presages at last not absence and difference but fictive recovery of presence and identity, the one for whom poetry represents a way of belief beyond mysticism even as it bodes mythic proximity. Finally, this is the Stevens who predominates throughout the prose (as well as in much of the poetry), who tries mightily to secure a belief while disencumbering himself of metaphysics—but alas, I think, with small success. Although Stevens's association of the problem of belief with the idea of fiction occurs in early poems such as "A High-Toned Old Christian 79 80Philosophy and Literature Woman" and "To the One of Fictive Music," his most intensive involvement with fiction as belief dates from the early 1940s and spans the period of his major essays and his last four volumes of poems. He recounts, for instance, a 1942 conversation with a student: "I said that I thought that we had reached a point at which we could no longer really believe in anything unless we recognized that it was a fiction. The student said that that was an impossibility, that there was no such thing as believing in something that one knew was not true. It is obvious, however, that we are doing that all the time" (L, p. 430). What does it mean to believe in a fiction? That is my main subject here, as we seek out the limits of the phenomenological Stevens. His letters of this period are preoccupied with the problem of fictive belief: "If one no longer believes in God (as truth), it is not possible merely to disbelieve; it becomes necessary to believe in something else.... A good deal of my poetry recently has concerned an identity for that thing.... In one of the short poems that I have just sent to the harvard advocate, I say that one's final belief must be in a fiction. I think that the history of belief will show that it has always been in a fiction" (L, p. 370). The poem referred to, "Asides on the Oboe," begins: The prologues are over. It is a question now, Of final belief. So, say that final belief Must be in a fiction. It is time to choose. (CP, p. 250) Acknowledging that "in the long run, poetry would be the supreme fiction" (L, pp. 430-31), Stevens nonetheless singles out the nominative function of poetry as the essence of its claim to supremacy: "Poetry means not the language of poetry but the thing itself.... The subject matter is what comes to mind when one says of the month of August... 'Thou art not August, unless I make thee so'" (L, p. 377). The quoted line (also from "Asides") underscores the paradox that for Stevens the essence of fiction (the nontrue) is its capacity to nominate the true or the real. This... (shrink)

An edited version of a talk between Urban and Toynbee on Radio Free Europe. The book concerns the nature of history as well as discussing Marxism and Christianity, the third world, and the effects of technology.

In the late Middle Ages, Chaucer invents two imaginative domains crucial to his culture and to our understanding of the emergence of selfhood, subjectivity and social arrangements; antiquity and late-medieval modernity. Edwards demonstrates in this study how this was the result of Chaucer's reading and re-writing of the works of Boccaccio, which provide sources and models for portraying the classical past and medieval modernity. In so doing, Edwards provides us with a valuable way of assessing Chaucer's analysis of late medieval (...) culture. (shrink)

This study explores Jihadist Salafism within Salafist Islam, characterized by its adherence to early Islamic practices and interpretations, advocating extreme and often violent approaches, including armed struggle, to achieve ideological objectives, deviating from mainstream Salafist principles. Despite considerable research on Salafism, understanding within the Turkish context remains limited. Salafist ideology in Turkey emerged in the 1980s, gaining momentum post-9/11 and peaking during the Syrian civil war. Focusing on Halis Bayancuk (Abu Hanzala), a prominent figure in Turkish politics and founder of (...) the Tawhid and Sunnah Community, known for his strict adherence to Salafist principles, this study meticulously analyzes his ideology, intertwined with a deep exploration of jihad principles. Using Quintan Wiktorowicz’s framework, Salafists are categorized into purists, politicos, and jihadists. The research aims to uncover nuances and insights about Salafist ideology in Turkey by employing document analysis. It uses discourse analysis to study Abu Hanzala’s religious and political views, aiming to provide a detailed understanding of Salafism’s complex structure in Turkey and its manifestation in the socio-political landscape.
