An objection to reductionism in the epistemology of testimony that is often repeated but rarely defended in detail is that there is not enough positive evidence to provide the non-testimonial, positive reasons reductionism requires. Thus, on pain of testimonial skepticism, reductionism must be rejected. Call this argument the ‘Not Enough Evidence Objection’. I will defend reductionism about testimonial evidence against the NEEO by arguing that we typically have non-testimonial positive reasons in the form of evidence about our testifier's evidence. With (...) a higher-level evidence principle borrowed from recent work on the epistemology of disagreement, I argue that, granting some plausible assumptions about conversational norms, the NEEO is unsound.

This study is an unusual contribution to the philosophy of mind in that it argues for the sometimes unfashionable view of dualism: that mind and matter are distinct and separate entities as Descartes believed. The author takes as his point of departure the imaginative hypothesis of disembodiment, which establishes the possibility of the mind's being a quite non-material thing. There are clear casual correlations between what is physical and what is mental, and the most serious issue confronting dualism since Descartes (...) has been how such an interaction is possible. Dr Hart sets out to answer this question by showing that the issue is as much about the nature of causation as it is about the natures of mind and matter. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:What Do You Mean, Rhetoric Is Epistemic?William D. HarpineIn 1967, Robert L. Scott (1967) advocated that "rhetoric is epistemic." This concept has enriched the work of rhetorical theorists and critics. Scott's essay is founded in a concept of argumentative justification in rhetoric, viewed as an alternative to analytic logic. Other writers, including Brummett (1976), Railsback (1983), and Cherwitz and Hikins (1986), have offered variations on Scott's theme. The (...) thesis that rhetoric is epistemic has been controversial, however, and from the tone of the debate one may draw two conclusions: many rhetorical theorists feel that Scott was on to something important, and the thesis as it has been developed is flawed. Much of the dispute centers on what the thesis means. These discussions have not yet adequately clarified that issue.The philosopher's most fundamental obligation is to define terms with care. It is in precisely this respect that the rhetoric-is-epistemic theorists have fallen short. Some of the key terms in this literature include rhetoric, knowledge, certainty, and truth. In too many cases, the writers on rhetorical epistemology have not defined their key terms at all. In other cases, their definitions are inadequate or inconsistent. This essay undertakes to sort out the most important definitional problems, which center on the rhetoric-is-epistemic theorists' habit of equivocating about the meanings of "rhetoric" and "certainty." The result makes it possible to endorse the validity of Scott's essentially ethical conclusions, while dismissing a number of unnecessary complexities in the arguments made by rhetoric-as-epistemic theorists. Finally, a few alternatives that might lead to more robust foundations for the rhetoric-as-epistemic thesis are suggested.In 1978, after reviewing four distinct interpretations of the claim that rhetoric is epistemic, Leff concluded that clarification of what that claim means "deserves more disciplined treatment than it has received in the recent literature" (1978, 77). The same could still be said. After some [End Page 335] thirty years of active research and speculation on the topic, one now sees fewer publications specifically advocating that rhetoric is epistemic. The distinguished rhetorical theorist Barry Brummett (1990) has declared the thesis deceased (69-72).All the same, textbook authors treat the thesis as a given, despite their tendency to interpret it in wildly different ways. Foss, for example, puts forward a view that "in the field of communication, the idea that rhetoric creates reality is known as the notion that rhetoric is epistemic, which simply means that rhetoric creates knowledge; epistemology is the study of the origin and nature of knowledge" (1989, 122; emphasis in the original). This version of the thesis, claiming that rhetoric actually "creates reality," might be more ontological than it is epistemic.1 Herrick takes a dialectical view that "through rhetorical interaction, people come to accept some ideas as true and to reject others as false. Thus, rhetoric's epistemic function in society can be seen in some ways to be a result of its benefit of testing ideas." Herrick continues that "once an idea has been tested thoroughly by a group, community, and society, it becomes part of what these groups take to be knowledge." Herrick contrasts this with the rejected view that "knowledge is all objective in nature and comes to us by way of direct experience or education" (1997, 22). Both Herrick and Foss offer interesting theses, and both attribute their views to Scott, but their views are obviously very different. There can be no surer evidence of the failure to use terms precisely.Brummett (1990) attributes the demise of rhetoric-is-epistemic research to the failure of critics to employ the idea in rhetorical criticism. Brummett might be right to the extent that much of the rhetoric-is-epistemic literature is indeed exceptionally abstract. Specific discussions might clarify some issues. Nonetheless, some notable rhetorical critics have indeed employed a concept that rhetoric is epistemic (e.g., Scott and Klumpp 1984; Sullivan 1992). The issues remain unclear. Furthermore, rhetorical criticism per se cannot clarify the meanings of theoretical terms. More likely, one sees less and less published research about the thesis that rhetoric is epistemic precisely because the thesis has not been laid out clearly... (shrink)

In Natural Ethical Facts William Casebeer argues that we can articulate a fully naturalized ethical theory using concepts from evolutionary biology and cognitive science, and that we can study moral cognition just as we study other forms of cognition. His goal is to show that we have "softly fixed" human natures, that these natures are evolved, and that our lives go well or badly depending on how we satisfy the functional demands of these natures. Natural Ethical Facts is a (...) comprehensive examination of what a plausible moral science would look like.Casebeer begins by discussing the nature of ethics and the possible relationship between science and ethics. He then addresses David Hume's naturalistic fallacy and G. E. Moore's open-question argument, drawing on the work of John Dewey and W. V. O. Quine. He then proposes a functional account of ethics, offering corresponding biological and moral descriptions. Discussing in detail the neural correlates of moral cognition, he argues that neural networks can be used to model ethical function. He then discusses the impact his views of moral epistemology and ontology will have on traditional ethical theory and moral education, concluding that there is room for other moral theories as long as they take into consideration the functional aspect of ethics; the pragmatic neo-Aristotelian virtue theory he proposes thus serves as a moral "big tent." Finally, he addresses objections to ethical naturalism that may arise, and calls for a reconciliation of the sciences and the humanities. "Living well," Casebeer writes, "depends upon reweaving our ethical theories into the warp and woof of our scientific heritage, attending to the myriad consequences such a project will have for the way we live our lives and the manner in which we structure our collective moral institutions.".

Discriminating behavior depends on neural representations in which the sensory activity patterns guiding different responses are decorrelated from one another. Visual information can often be parsimoniously transformed into these behavioral bridge-locus representations within neuro-computational visuo-spatial maps. Isomorphic inverse-optical world representation is not the goal. Nevertheless, such useful transformations can involve neural filling-in. Such a subpersonal representation of information is consistent with personal-level vision theory.

Although Hegel is generally understood as a thinker of modernity, this volume argues that his modernity can only be understood in essential relation to classical antiquity. It explores his readings of the ancient Graeco-Roman world in each of the major areas of his historical thinking in turn, from politics and art to history itself.

The dissertation is a detailed philosophical interpretation of the entire text of Plato's Sophist. In addition to extended analysis of the argument and discussion of many current interpretations, special attention is given to the following themes as they occur in other Platonic dialogues as well as the Sophist: ; Plato's theory of Knowledge: What is it that can be known? And how does one get to know it? Do the Sophist and other late dialogues show a change in Plato's views, (...) or an elaboration of views he held when he wrote such works as the Phaedo and the Republic? ;: these fall into three types: those with propositional structures, those which are structured like descriptions, i.e. denoting complexes, and definitions, which are denoting complexes of a special sort. Each of these types is discussed, and the role of definitions in Plato's theory of knowledge is explained. ; Judgments: what is a judgment, or opinion? How does a judgment come to be made? Plato distinguished questions about the internal structure of judgments or opinions from questions about what is involved in a person's coming to judge, or believe, or opine something. Both sorts of questions are discussed in the dissertation. ; Truth and falsity: two notions of truth, together with corresponding notions of falsity, are distinguished. One is a notion of truth as predicated of propositionally structured simpliciter. This is the notion which plays a dominate role in the Sophist. The other notion, which rears its head in the Cratylus and a short section of the Phaedrus, if a notion of true of as predicted of names and and what they are said of. Both notions, and other notions of truth held by Plato's philosophical opponents, are explained and discussed. ; Negation: What is the problem about being and not being^which arises in the Sophist? How is it related to the problem raised^as to how false judgments and are possible? Plato believed^that Parmenides made a mistaken assumption about negation, and^that that assumption could be used by sophists such as Protagoras^and Gorgias to undermine the thesis that mistaken judgments and^false occur. The central pages of the Sophist are devoted to^uncovering Parmenides' error, and to offering a replacement for the^assumption which Plato rejects. Plato then shows how the replacement he suggests can beused in an analysis of true and false and judgments. ;Numerous other themes arise in the course of the analysis of the argument--Plato's notions of time and change, of images, of explanation, etc. These, too, are discussed. There are twenty one appendices containing discussions of points of translation, alternative interpretations of key passages, formal proofs not appropriate for inclusion in the main body of the text and too extended for footnotes, and remarks on various passages occurring in other Platonic dialogues helpful in glossing the Sophist.

In the fall of 1869, the first of eight students set off from the tiny Sadowara Domain in southeastern Kyushu to pursue study in America and Europe. Overshadowed by more famous peers from other domains, the Sadowara students have been all but forgotten, and their lives abroad remain an untold story. Yet they played an important role in the early development of Japanese studies in the United States. Enrolling at diverse institutions mostly in the Northeast, six of the students came (...) to form a close relationship with Yale’s university librarian, a philologist named Addison Van Name. Inspired by his new friends to study the Japanese language, within a year Van Name was offering America’s first college course in Japanese, and he quickly began to produce scholarship on Japan and its language, literature, and history. By the mid-1870s, the Sadowara students had returned to their home country, where their subsequent careers constituted a microcosm of the paradox and transformation of the early Meiji period. Van Name maintained contact with his Japanese friends, and through this long-distance relationship succeeded in building America’s first significant Japanese library collection: a 3,000-volume collection of Edo and early Meiji titles that still survives today.

The developing neuromuscular junction has provided an important paradigm for studying synapse formation. An outstanding feature of neuromuscular differentiation is the aggregation of acetylcholine receptors (AChRs) at high density in the postsynaptic membrane. While AChR aggregation is generally believed to be induced by the nerve, the mechanisms underlying aggregation remain to be clarified. A 43‐kD protein (43k) normally associated with the cytoplasmic aspect of AChR clusters has long been suspected of immobilizing AChRs by linking them to the cytoskeleton. In recent (...) studies, the AChR clustering activity of 43k has, at last, been demonstrated by expressing recombinant AChR and 43k in non‐muscle cells. Mutagenesis of 43k has revealed distinct domains within the primary structure which may be responsible for plasma membrane targeting and AChR binding. Other lines of study have provided clues as to how nerve‐derived (extracellular) AChR‐cluster inducing factors such as agrin might activate 43k‐driven postsynaptic membrane specialization. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:“Analyzing How Rhetoric is Epistemic”:A Reply to Steve FullerWilliam D. HarpineMy point in "What Do You Mean, Rhetoric Is Epistemic" (Harpine 2004) is that unclear and inconsistent use of terms has hindered previous research on the idea that rhetoric is epistemic. I propose to clarify definitions to alleviate this problem and encourage further research into how rhetoric might be epistemic. Professor Fuller's viewpoint is that definitions are inherently problematic, (...) and that my call for rhetoric-is-epistemic theorists to formulate their definitions more carefully would hold rhetorical theory to "illusory" standards (Fuller 2005, 72). However, I feel that his criticism of definitions overstates what his arguments demonstrate. Fuller (2005) also expresses doubts about the concept of certainty, doubts which echo points in my essay. Along the way, he offers an interesting line of reasoning that might advance the dialogue in the way that I had hoped. To an extent, Fuller seems to reach similar conclusions about the relationship between rhetoric and knowledge, albeit by a different route.CertaintyMy essay argues that certain claims of rhetoric-is-epistemic theorists trade on an equivocation about the meaning of "certainty." The word "certain" can carry an objective meaning: "It is certain that I will have to pay taxes," or it can be subjective: "I feel certain that I will have to pay taxes." An ordinary person can easily see that the two claims mean something different. Although Wittgenstein explains this distinction most clearly, in a statement that Fuller (2005) himself quotes, the distinction routinely arises in everyday discourse. An argument that works surreptitiously by sliding from one of these meanings to the other commits the fallacy of equivocation. The rhetoric-is-epistemic literature does exactly that all too often. [End Page 82]On this matter, expressing doubts about objective certainty, Fuller comments that the role of certainty in philosophy is inconclusive (2005, 78). I fully agree with this point. My argument is to show how rhetoric-is-epistemic theorists fallaciously rely on an ambiguity in meaning, not to claim that some things really are objectively certain. It is not the purpose of rhetoric-is-epistemic theorists to argue that nothing is certain—there are much more straightforward ways to do that—but to show that rhetoric has an epistemic role. To accomplish this, they need an argument that does not short-circuit by equivocating in the use of key terms. In any case, my essay notes that "the current philosophical literature has not taken a strong stance in favor of requiring knowledge to be either objectively or subjectively certain," which resembles Fuller's own conclusion, and also that rhetoric-is-epistemic theorists "should dispense with the issue of certainty" (Harpine 2004, 346), which, if Fuller agrees (as I suspect he does), renders further details moot.KnowledgeMost rhetoric-is-epistemic theorists work either explicitly or implicitly with the traditional definition that knowledge is justified true belief. They point out that rhetoric offers justification. Gettier's argument shows that the traditional definition fails to capture the meaning of "knowledge." Thus, the rhetoric-is-epistemic theorists have a problem tying their theory to their conception of knowledge. The point is not that different rhetoric-is-epistemic theorists have used different definitions of knowledge, but rather that they work with an inadequate definition. Fuller agrees with Gettier's point, gives additional arguments on its behalf, and offers an interesting discussion of the rhetorical implications of Gettier's argument. Since Gettier's argument may lead one to question whether justification is a defining quality of knowledge, rhetoric-is-epistemic theorists might look for other kinds of linkages between rhetoric and knowledge. The concluding portions of my essay suggest several such possible linkages.1Does my argument resemble the Babel thesis? Elsewhere, Fuller (2002, 104) explains the Babel thesis as the claim that disagreements are due to different meanings, not to different beliefs. One must agree with Fuller that the Babel thesis overstates the importance of meaning. However, a similar insight arises in more modest guise as Davidson's principle [End Page 83] of charity. Studying intercultural relationships, Davidson (1984, 136) suggests that when we encounter people whose beliefs differ from ours, we... (shrink)

The present paper defends the thesis that Spenser's recovery of place, as enacted in 'The Faerie Queene,' Book VI, can be linked in a direct way to his use of a poetic phenomenology which informs and clarifies his work as an epic writer. Spenser's "Book of Courtesy" enacts a Neo-Platonic movement from the lower levels of temporal existence to an exalted vision of spiritual perfection. The paper explores this movement along phenomenological lines as a mysterious adventure that embraces self and (...) other, personality and community, aesthetics and ethics, in a sequence of images that opens up a new interpretation of imaginative fulfillment. -/- .

In a previous article, we challenged the “incentivization view” held by J. P. Smit, Filip Buekens, and Stan du Plessis as failing to cover social phenomena involving strict joint actions.

This article demonstrates how a new reading of Rilke’s poetry can provide a basis for comparing and contrasting the aesthetic approach to art and the language-based approach that foregrounds the role of metaphor and materiality in literary production. Lessing’s Laocoön is discussed in terms of an implied dialogue between painting and poetry, which, however, acquires a different valence when the Fifth of Rilke’s 'Duino Elegies' suggests that poetry itself functions as a ‘metaphorical hypoicon’ allowing for shared meanings. My concluding remarks (...) emphasize the importance of the performing self to a complete understanding of Rilke’s semiotic potential. (shrink)

Material Difference: Modernism and the Allegories of Discourse argues that deconstruction can be employed in conjunction with the historically-oriented approach to cultural experience that is favored by Critical Theory. The two discourses that inform this comparative study situate Modernism between evolving traditions that begin with Hegel and Nietzsche, leading on to Adorno's commitment to philosophical aesthetics and Derrida's concern for writing (écriture). Interrelated discussions of eight major authors, working in four different languages, are presented to show how allegorical Modernism foreshadows (...) the possibility of cultural history. Joyce, Kafka, Malraux, Rilke, and Stevens are among the authors discussed in this book. The notion of material difference allows literature to be redefined in semiotic terms and demonstrates how the allegorical imagination mediates between art and time. (shrink)

IntroductionChildren with severe physical disabilities are denied their fundamental right to move, restricting their development, independence, and participation in life. Brain-computer interfaces (BCIs) could enable children with complex physical needs to access power mobility (PM) devices, which could help them move safely and independently. BCIs have been studied for PM control for adults but remain unexamined in children. In this study, we explored the feasibility of BCI-enabled PM control for children with severe physical disabilities, assessing BCI performance, standard PM skills (...) and tolerability of BCI.Materials and methodsPatient-oriented pilot trial. Eight children with quadriplegic cerebral palsy attended two sessions where they used a simple, commercial-grade BCI system to activate a PM trainer device. Performance was assessed through controlled activation trials (holding the PM device still or activating it upon verbal and visual cueing), and basic PM skills (driving time, number of activations, stopping) were assessed through distance trials. Setup and calibration times, headset tolerability, workload, and patient/caregiver experience were also evaluated.ResultsAll participants completed the study with favorable tolerability and no serious adverse events or technological challenges. Average control accuracy was 78.3 ± 12.1%, participants were more reliably able to activate (95.7 ± 11.3%) the device than hold still (62.1 ± 23.7%). Positive trends were observed between performance and prior BCI experience and age. Participants were able to drive the PM device continuously an average of 1.5 meters for 3.0 s. They were able to stop at a target 53.1 ± 23.3% of the time, with significant variability. Participants tolerated the headset well, experienced mild-to-moderate workload and setup/calibration times were found to be practical. Participants were proud of their performance and both participants and families were eager to participate in future power mobility sessions.DiscussionBCI-enabled PM access appears feasible in disabled children based on evaluations of performance, tolerability, workload, and setup/calibration. Performance was comparable to existing pediatric BCI literature and surpasses established cut-off thresholds (70%) of “effective” BCI use. Participants exhibited PM skills that would categorize them as “emerging operational learners.” Continued exploration of BCI-enabled PM for children with severe physical disabilities is justified.
