ABSTRACT In the ‘Cook Ding cutting up an ox’ parable, Zhuangzi advanced a doctrine on craft and its relationship with Dao. With reference to Merleau-Ponty’s philosophy in conjunction with an analysis of Zhuangzi’s epistemological position, we argue that Zhuangzi understood craft as involving the supersession of the cognitive. In craft, the relationship between human and world is non-cognitive and ‘pre-objective’, the living of this kind of relationship gives rise to a non-cognitive ‘practical sense’ which enables the craftsman’s movements to spontaneously (...) constitute wuwei. Zhuangzi’s ideal is that this kind of relationship is generalized to life as a whole, thereby enabling human actions to spontaneously constitute wuwei generally. This is why he stipulated ‘doing away with knowing’ as a self-cultivation technique required for attaining Dao. Thus, craft constitutes an embodiment of Dao in the double-sense of wuwei and the non-cognitive and ‘pre-objective’ relationship between human and world which enables wuwei. (shrink)

Background: Parkinson’s disease is a neurodegenerative disease in which the progressive loss of dopaminergic neurons leads to initially sporadic and eventually widespread damage of the nervous system resulting in significant musculoskeletal and cognitive deterioration. Loss of motor function alongside increasing cognitive impairment is part of the natural disease progression. Gait is often considered an automatic activity; however, walking is the result of a delicate balance of multiple systems which maintain the body’s center of mass over an ever-changing base of support. (...) It is a complex motor behavior that requires components of attention and memory to prevent falls and injury. In addition, evidence points to the critical role of salient visual information to gait adaptability. There is a growing understanding that treatment for PD needs to address movement as it occurs naturally and walking needs to be practiced in more complex environments than traditional therapy has provided.MethodsIn this single-blinded randomized-controlled pilot study, an immersive treadmill training was piloted to determine feasibility and preliminary efficacy on gait and cognition in people with PD. Eighteen participants with Hoehn and Yahr stages I-III PD were randomized to either an intervention or a waitlist control group. Following baseline data collection, the intervention group trained for 30 min, three times/week for 4 weeks on a split belt treadmill combined with a first-person immersive video game targeting visuospatial skills and working memory. Assessment was repeated after 4 weeks of training for the experimental group and 1-month after baseline for the control group. Primary motor outcomes were captured with the APDM Opal sensors during 6 MWT, TUG, and TUG Cognitive. Secondary outcomes of cognition were measured with the Montreal Cognitive Assessment, Verbal Fluency and the Symbol Digit Modality Test. Within subject differences were calculated using the Wilcoxon Signed Ranked Test and between subject comparisons were analyzed using the Mann Whitney U-test.ResultsThis novel treadmill training program was well-tolerated with all participants in the intervention group completing 4 weeks of training three times a week without any adverse effects. After immersive cognitive motor training, the experimental group made clinically relevant improvements in gait speed and walking distance during the 6 MWT while members of the control group showed no change or decreased gait speed and walking distance over the 1-month trial. In addition, the experimental group demonstrated significant improvement for the TUG Cognitive and those changes were greater than the control group. The experimental group also improved scores on MoCA and SDMT cognitive outcome measures while the control group did not.ConclusionThe use of immersive gaming technology to engage specific areas of cognition related to gait is feasible in PD. The treadmill training program paired with a customized interactive video game improved walking velocity in addition to non-significant but consistent improvements in other gait measures and cognitive performance in participants with early to mid-stage PD.

The expressive power of logic is believed to be able to model most of the fundamental aspects of information retrieval. However, it is also understood that classical logic is ineffective for handling partiality and uncertainty in IR. Applying non-classical logics such as the AGM belief revision logic and the possibilistic logic to adaptive information retrieval is appealing since they provide a powerful and rigorous framework to model partiality and uncertainty inherent in any IR processes. The maxi-adjustment method, which is an (...) effective computational apparatus of the AGM paradigm, is applied to develop the learning components of the adaptive information agents. Essentially, maxi-adjustment allows the partial representation K of a user's information needs N to be refined gradually based on the user's relevance feedback t. Generally speaking, learning in adaptive information agents is characterised by the AGM belief revision Kt*. On the other hand, possibilistic logic supports a gradated assessment of the uncertainty arising from matching K with the imperfect characterisation d of an information object D. Information matching in adaptive information agents is underpinned by K ƕ d, where ƕ is the possibilistic inference relation. This paper illustrates how maxi-adjustment and possibilistic deduction can be applied to develop the adaptive information agents. Their impact on the agents learning autonomy and explanatory power is also discussed. (shrink)

Hand function improvement in stroke survivors in the chronic stage usually plateaus by 6 months. Brain-computer interface (BCI)-guided robot-assisted training has been shown to be effective for facilitating upper-limb motor function recovery in chronic stroke. However, the underlying neuroplasticity change is not well understood. This study aimed to investigate the whole-brain neuroplasticity changes after 20-session BCI-guided robot hand training, and whether the changes could be maintained at the 6-month follow-up. Therefore, the clinical improvement and the neurological changes before, immediately after, (...) and 6 months after training were explored in 14 chronic stroke subjects. The upper-limb motor function was assessed by Action Research Arm Test (ARAT) and Fugl-Meyer Assessment for Upper-Limb (FMA), and the neurological changes were assessed using resting-state functional magnetic resonance imaging. Repeated-measure ANOVAs indicated that long-term motor improvement was found by both FMA (F[2,26]= 6.367,p= 0.006) and ARAT (F[2,26]= 7.230,p= 0.003). Seed-based functional connectivity analysis exhibited that significantly modulated FC was observed between ipsilesional motor regions (primary motor cortex and supplementary motor area) and contralesional areas (supplementary motor area, premotor cortex, and superior parietal lobule), and the effects were sustained after 6 months. The fALFF analysis showed that local neuronal activities significantly increased in central, frontal and parietal regions, and the effects were also sustained after 6 months. Consistent results in FC and fALFF analyses demonstrated the increase of neural activities in sensorimotor and fronto-parietal regions, which were highly involved in the BCI-guided training.Clinical Trial Registration:This study has been registered atClinicalTrials.govwith clinical trial registration number NCT02323061.

Cognitive theories of metaphor understanding are typically described in terms of the mappings between different kinds of abstract, schematic, disembodied knowledge. My claim in this paper is that part of our ability to make sense of metaphorical language, both individual utterances and extended narratives, resides in the automatic construction of a simulation whereby we imagine performing the bodily actions referred to in the language. Thus, understanding metaphorical expressions like ‘grasp a concept’ or ‘get over’ an emotion involve simulating what it (...) must be like to engage in these specific activities, even though these actions are, strictly speaking, impossible to physically perform. This process of building a simulation, one that is fundamentally embodied in being constrained by past and present bodily experiences, has specific consequences for how verbal metaphors are understood, and how cognitive scientists, more generally, characterize the nature of metaphorical language and thought.

The specification and implementation of computational artefacts occurs throughout the discipline of computer science. Consequently, unpacking its nature should constitute one of the core areas of the philosophy of computer science. This paper presents a conceptual analysis of the central role of specification in the discipline.

This paper explores the trade-off between cognitive effort and cognitive effects during immediate metaphor comprehension. We specifically evaluate the fundamental claim of relevance theory that metaphor understanding, like all utterance interpretation, is constrained by the presumption of optimal relevance (Sperber and Wilson, 1995, p. 270): the ostensive stimulus is relevant enough for it to be worth the addressee’s effort to process it, and the ostensive stimulus is the most relevant one compatible with the communicator’s abilities and preferences. One important implication (...) of optimal relevance is that listeners follow a path of least effort and stop processing at the first interpretation that satisfies their expectation of relevance. They do this by trying to minimize cognitive effort while maximizing cognitive effects. Some relevance theory scholars suggest that metaphors should require additional cognitive effort to be understood, and that in return they yield more cognitive effects than does literal speech. Others claim that metaphors may be understood quickly, as soon as people infer enough effects for the speaker’s utterance to meet their expectation of optimal relevance. Our analysis of the experimental evidence suggests that there is no systematic relationship between cognitive effort and cognitive effects in metaphor comprehension. We conclude that relevance theory need not make any general predictions about the effort needed to comprehend metaphors. Nevertheless, relevance theory is consistent with many of the findings in psycholinguistics on metaphor understanding, and can account for aspects of metaphor understanding that no other theory can explain.

The relationship between sociology and bioethics has been an uneasy one. It has been described as contentious and adversarial, and at least some of the sociologists who have ventured into the territory of medical ethics report back on unfriendly natives. This bioethical ill will toward sociology is not without cause. Sociologists have been quite critical of what they call (with not-so-subtle pejorative overtones) the bioethical project.Two decades ago - when bioethics was just getting up on its organizational feet - Renée (...) Fox and Judith Swazey leveled the charge of cultural myopia against bioethics, noting that this myopia generally manifests itself in the form of systematic inattention to the social and cultural sources and implications of its own thought. They go on to sayifbioethics is an indicator of the general state of American ideas, values, and beliefs, of our collective self knowledge, and our understanding of other societies and cultures - then there is every reason to be worried about who we are, what we have become, and where we are going.

This article documents experiences of Glasgow Improvisers Orchestra’s virtual, synchronous improvisation sessions during COVID-19 pandemic via interviews with 29 participants. Sessions included an international, gender balanced, and cross generational group of over 70 musicians all of whom were living under conditions of social distancing. All sessions were recorded using Zoom software. After 3 months of twice weekly improvisation sessions, 29 interviews with participants were undertaken, recorded, transcribed, and analyzed. Key themes include how the sessions provided opportunities for artistic development, enhanced (...) mood, reduced feelings of isolation, and sustained and developed community. Particular attention is placed upon how improvisation as a universal, real time, social, and collaborative process facilitates interaction, allowing the technological affordances of software (latencies, sound quality, and gallery/speaker view) and hardware (laptop, tablet, instruments, microphones, headphones, and objects in room) to become emergent properties of artistic collaborations. The extent to which this process affects new perceptual and conceptual breakthroughs for practitioners is discussed as is the crucial and innovative relationship between audio and visual elements. Analysis of edited films of the sessions highlight artistic and theoretical and conceptual issues discussed. Emphasis is given to how the domestic environment merges with technologies to createThe Theatre of Home. (shrink)

Considerable research on helpers-at-the-nest demonstrates the positive effects of firstborn daughters on a mother’s reproductive success and the survival of her children compared with women who have firstborn sons. This research is largely restricted to agricultural settings. In the present study we ask: “Does ‘daughter first’ improve mothers’ reproductive success in a hunting and gathering context?” Through an analysis of 84 postreproductive women in this population we find that the sex of the first- or second-born child has no effect on (...) a mother’s fertility or the survival of her offspring. We conclude that specific environmental and economic factors underlay the helpers-at-the-nest phenomenon. (shrink)

When athletes make significant plays in sporting competitions, such as scoring a goal in soccer, a touchdown in American football, they often immediately express their joy by performing some bodily action for others to see and understand. Many sports celebrations are staged pantomimes that express metaphorical meanings as a part of athletes’ pretending to perform certain source-path-goal sequences of action from other competitive events. This article examines the possible metaphoricity in different sports celebrations and whether casual observers may understand these (...) actions as conveying metaphorical messages. Studies 1 and 3 present analyses of some of the important, possibly metaphorical, characteristics of a corpus of sports celebrations, both those that are performed by individual athletes (Study 1) and those where several athletes jointly enact some celebratory action (Study 3). Studies 2 (individual athletes) and 4 (group performances) investigated whether casual spectators interpret some celebrations as conveying metaphorical messages beyond simply expressing an athlete’s positive emotions. These studies demonstrate that many sports celebrations express metaphorical meanings where athletes provide bodily commentary on the significance of what they have just accomplished. (shrink)

A collection of paradoxes, dialogues, problems, and essays discusses aspects of philosophy, including the natures of reality, truth, existence, and death.

Peter French has argued that conglomerate collectivities such as business corporations are moral persons and that aggregate collectivities such as lynch mobs are not. Two arguments are advanced to show that French's claim is flawed. First, the distinction between aggregates and conglomerates is, at best, a distinction of degree, not kind. Moreover, some aggregates show evidence of moral personhood. Second, French's criterion for distinguishing aggregates and conglomerates is based on inadequate grounds. Application of the criterion to specific cases requires an (...) additional judgment of a pragmatic nature which undermines any attempt to demonstrate French's thesis that actual conglomerates are moral persons and aggregates are not. Thus, French's theory is seriously lacking both empirical basis and empirical relevance. (shrink)

ABSTRACTTreating conditionals as probabilistic statements has been referred to as a defining feature of the “new paradigm” in cognitive psychology. Doing so is attractive for several reasons, but it complicates the problem of assessing the merits of conditional arguments. We consider several variables that relate to judging the persuasiveness of conditional arguments with uncertain premises. We also explore ways of judging the consistency of people's beliefs as represented by components of conditional arguments. Experimental results provide evidence that inconsistencies in beliefs (...) are more prevalent if the arguments’ components are spatially and temporally dispersed than if they are contiguous in space and time. This supports the idea that assuring the consistency among even a small number of beliefs is difficult to do, especially if the beliefs in question are not brought into consciousness at the same time; but consistency can be enhanced when beliefs are considered simultaneously or nea...

A fundamental question in philosophy of religion is whether religious belief must be based on evidence in order to be properly held. In recent years two prominent positions on this issue have been staked out: evidentialism, which claims that proper religious belief requires evidence; and Reformed epistemology, which claims that it does not. Evidence and Religious Belief contains eleven chapters by prominent philosophers which push the discussion in new directions. The volume has three parts. The first part explores the demand (...) for evidence: some chapters object to it while others seek to restate it or find space for compromise between Reformed epistemology and evidentialism. The second part explores ways in which beliefs are related to evidence; that is, ways in which the evidence for or against religious belief that is available to a person can depend on that person's background beliefs and other circumstances. The third part contains chapters that discuss actual evidence for and against religious belief. Evidence for belief in God includes the so-called common consent of the human race and the way that such belief makes sense of the moral life; evidence against it includes profound puzzles about divine freedom which suggest that it is impossible for a being to be morally perfect.

In this paper it is argued that certain stimulus-response learning models which are adequate to represent finite automata (acceptors) are not adequate to represent noninitial state input-output automata (transducers). This circumstance suggests the question whether or not the behavior of animals if satisfactorily modelled by automata is predictive. It is argued in partial answer that there are automata which can be explained in the sense that their transition and output functions can be described (roughly, Hempel-type covering law explanation) while their (...) behaviors are in principle not predictable short of possession of their complete histories or of information concerning present internal states by indirect observation.

This work subjects the fundamental ideas of Derrida, Lacan, Barthes and their followers to an examination and demonstrates the baselessness of post-Saussurean claims about the relations between language, reality and self.

Ever since language has been examined as a vehicle for action, scholars have been interested in its authorized use. Typically described under the rubric of `felicity conditions', the authorized use of language involves, among other conditions, the right or authority of a member to engage in, or deploy, some named action. This paper begins by examining how participants authorize the discourse of a co-interactant in one specialized setting: a live news broadcast. I argue that the successful exploitation by a reporter (...) of his/her right to authoritatively describe a scene all are witnessing rests in part on the displayed mutual orientation of his or her co-interactants to that right through the local, contingently achieved deployment of complex discursive practices. After exploring the special case of live news broadcasts, I link this study to other studies of mass media that have explored the link between discursive practices in news broadcasts and reportorial authority. Finally, I argue that the resources I have identified have a more general provenance than live news broadcasts, and reflect on the relation between these findings and recent discussions that explore the authorized use of language.

The concept of vulnerability has been the topic of considerable discussion in research bioethics, largely because of dissatisfaction with early constructions of the concept that were based on subpopulations of research subjects. These subpopulations have attributes likely to undermine their capacity to provide autonomous informed consent: persons who are relatively or absolutely incapable of protecting their own interests through negotiations for informed consent. Several subpopulations were seen as requiring special protections, including children, pregnant women, prisoners, racial minorities, the economically disadvantaged, (...) the very sick, and the institutionalized. Recent years have witnessed the identification of other subpopulations with attributes that could render them vulnerable, as well. For example, the Council for the International Organization of Medical Societies has named such potentially vulnerable groups as the homeless, nursing home residents, patients with incurable diseases, patients in the emergency department, employees, students, and members of communities who are unfamiliar with modern medicine.

When speakers utter metaphors, such as "Lawyers are also sharks," they often intend to communicate messages beyond those expressed by the metaphorical meaning of these expressions. For instance, in some circumstances, a speaker may state "Lawyers are also sharks" to strengthen a previous speaker's negative beliefs about lawyers, to add new information about lawyers to listeners to some context, or even to contradict a previous speaker's positive assertions about lawyers. In each case, speaking metaphorically communicates one of these three social (...) messages that are relevant to the ongoing discourse. At the same time, speaking metaphorically may express other social and affective information that is more difficult to convey using non-metaphorical speech, such as "Lawyers are also aggressive." We report the results of three experiments demonstrating that people infer different pragmatic messages from metaphors in varying social situations and that many metaphors can express additional pragmatic and rhetorical meanings beyond those conveyed by non-metaphorical language. These findings demonstrate the importance of trade-offs between cognitive effort and cognitive effects in pragmatic theories of metaphor use and understanding. (shrink)
