The rubber hand paradigm is used to create the illusion of self-touch, by having the participant administer stimulation to a prosthetic hand while the Examiner, with an identical stimulus , administers stimulation to the participant’s hand. With synchronous stimulation, participants experience the compelling illusion that they are touching their own hand. In the current study, the robustness of this illusion was assessed using incongruent stimuli. The participant used the index finger of the right hand to administer stimulation to a prosthetic (...) hand while the Examiner used a paintbrush to administer stimulation to the participant’s left hand. The results indicate that this violation of tactile expectations does not diminish the illusion of self-touch. Participants experienced the illusion despite the use of incongruent stimuli, both when vision was precluded and when visual feedback provided clear evidence of the tactile mismatch. (shrink)

Les résultats quantitatifs que la psychologie et la physiologie n'ont cessé d'accumuler depuis le début du siecle à propos du sens tactile laissent apparaître aujourd'hui une certaine ambiguïteé. D'un côté en effet, la préoccupation de connaître les sensibilities cutanées spécifiques telles qu'elles se présentent de manière isolée à l'analyse objective des récepteurs stimulés: les sensations de chaud et de froid, de pression et de contact, de douleur, de vibration. D'un autre côté, le désir de sauvegarder l'unité fonctionnelle du sens (...) tactile c.a.d. sa spécificité propre par rapport aux quatre autres sens traditionnels. Ainsi, par exemple, une analyse neurophysiologique des récepteurs tactiles5 ne manque pas de mentionner plusieurs catégories fonctionnelles de la sensibilité cutanée: la douleur, comme signal d'un danger qui peut menacer l'existence de l'organisme; la perception des qualités d'un objet, comme intégration du toucher et de la kinesthésie au cours d'une exploration active de la main; les expériences somatiques complexes telles que le chatouillement et les sensations sexuelles. Pour le phénoménologue, un tel compromis s'apparente à une confusion et provient des positions épistémologiques qui ont animé l'orientation méthodologique des recherches, depuis la psychophysiologie mécaniste jusqu'à la psychologie cybernétique de l'information sensorielle. En cela, la domaine de la sensation tactile reste l'apanage de la psychophysique, et nous tenterons de clarifier pourquoi cette position ne peut aboutir qu'à des résultats problématiques. A partir d'une psychologie anthropologique du sens tactile,14 nous défendrons l'idée d'une psychologie comparée qui permettrait une investigation empirique, objective des comportements animaux, sur la base de prolégomènes phénoménologiques.

Predictable somatosensory feedback leads to a reduction in tactile sensitivity. This phenomenon, called tactile suppression, relies on a mechanism that uses an efference copy of motor commands to help select relevant aspects of incoming sensory signals. We investigated whether tactile suppression is modulated by the task-relevancy of the predicted consequences of movement and the intensity of related somatosensory feedback signals. Participants reached to a target region in the air in front of a screen; visual or tactile (...) feedback indicated the reach was successful. Furthermore, tactile feedback intensity varied across two groups of participants. We measured tactile suppression by comparing detection thresholds for a probing vibration applied to the finger either early or late during reach and at rest. As expected, we found an overall decrease in late-reach suppression, as no touch was involved at the end of the reach. We observed an increase in the degree of tactile suppression when strong tactile feedback was given at the end of the reach, compared to when weak tactile feedback or visual feedback was given. Our results suggest that the extent of tactile suppression can be adapted to different demands of somatosensory processing. Downregulation of this mechanism is invoked only when the consequences of missing a weak movement sequence are severe for the task. The decisive factor for the presence of tactile suppression seems not to be the predicted action effect as such, but the need to detect and process anticipated feedback signals occurring during movement.

Bizarre delusions are not specific to schizophrenia and can be found in other psychotic disorders. However, to date, there are no studies investigating socio-demographic and clinical characteristics associated with BizD across the psychosis spectrum. In this study 819 subjects with a diagnosis of SZ, schizoaffective disorder and bipolar I disorder were included. Patients with history of BizD and with no BizD were compared with respect to socidemographic and clinical variables, and predictors of BizD were explored. Patients with BizD were less (...) educated, less likely to be married, had higher Positive and Negative Syndrome Scale negative scores and lower Young Mania Rating Scale scores. Younger age, SZ and SZA diagnoses, higher PANSS positive scores, presence of reference delusions, tactile and olfactory hallucinations were predictors. Our results indicate that BizD are associated with higher illness severity, lower functionality and specific set of symptoms. (shrink)

Do the authors intend to relate musicality to musical ability or aptitude as defined by psychologists? If musicality is "the ability to make something of one's own," does it mean that the authors have taken on a relativistic view and believe that musicality can be acquired?At the onset of the essay, musicality is described as emotional or cognitive phenomena. I would be interested to know what role a psychomotor phenomenon plays in musicality. The authors later describe "motor knowledge" in the context of Merleau-Ponty's "maximum grip." Does it mean that "motor knowledge" or "maximum grip" in music is outside the realm of musicality?I have attempted to follow the authors' logic in answering the question: What is learning of music? The authors postulate that "knowledge does not always, and not in any way automatically, become exactly the same as the learning situation aimed for" and that "the aim of music education is to produce music knowledge." These propositions lead me to believe that the learning of music occurs in experiencing all types of musical activities, regardless of the musician's level of proficiency. In all types of musical activities, including different performances of the same repertoire by the same performer, the musician would find new knowledge that is being produced in his/her body. Therefore, I agree with the authors in that "bodily experience is the foundation for learning."I would like to respond to the issue of whether music learning occurs within [End Page 206] or outside of the human being. I enjoy reading how the authors borrow Merleau-Ponty's analogy of the blind man and his stick. They put it so beautifully that "the piano becomes an extension of the pianist's body, and the pianist can 'feel' its limitation." This leads me to ponder if there could be further extensions beyond the physical piano. We know that pianists make the strings in the piano vibrate through a lever mechanism. These vibrations travel through the air and arrive at the audience's ears. Then the vibrating energies are transmitted as electrical energies in the audience's nerve cells. The audience in turn may behave differently after such a complex transmission of energies at a performance. My question is: Is there an end to the "extension" of a musician's body? If so, where should it end? There is no doubt that the pianist relates to the world and learns about the world through the piano. Could the pianist learn about the world through the vibrations that the piano strings generate, through the air, and through the audience's hearing mechanism, brain cells, and behaviors? Is this what the authors meant by "the human ego is boundaryless and cannot be localized, and the ego is immanent in the whole system"? Regardless of how far the "extension" goes, how do we know if an "extension" has occurred? How can we validate an "extension" of a musician's ego"?It seems to me that the authors' discussions have focused on the tactile extension of the body. If the body can be extended like the stick for the blind man, would the air surrounding the blind man, including its smell, temperature, humidity, wind, and sound, be his extension too? When this question is transferred to a musician, would the total context of the musical event be the musician's extension of the body too? By "total context," I mean the cultural context, the environment (smell, temperature,...), and the people in the musical event.We are certain that music learning takes place when experiences and knowledge are incorporated in the body.

Despite the recognized importance of bodily movements in spatial audition, few studies have integrated action-based protocols with spatial hearing in the peripersonal space. Recent work shows that tactile feedback and active exploration allow participants to improve performance in auditory distance perception tasks. However, the role of the different aspects involved in the learning phase, such as voluntary control of movement, proprioceptive cues, and the possibility of self-correcting errors, is still unclear. We study the effect of guided reaching exploration on (...) perceptual learning of auditory distance in peripersonal space. We implemented a pretest-posttest experimental design in which blindfolded participants must reach for a sound source located in this region. They were divided into three groups that were differentiated by the intermediate training phase: Guided, an experimenter guides the participant’s arm to contact the sound source; Active, the participant freely explores the space until contacting the source; and Control, without tactile feedback. The effects of exploration feedback on auditory distance perception in the peripersonal space are heterogeneous. Both the Guided and Active groups change their performance. However, participants in the Guided group tended to overestimate distances more than those in the Active group. The response error of the Guided group corresponds to a generalized calibration criterion over the entire range of reachable distances. Whereas the Active group made different adjustments for proximal and distal positions. The results suggest that guided exploration can induce changes on the boundary of the auditory reachable space. We postulate that aspects of agency such as initiation, control, and monitoring of movement, assume different degrees of involvement in both guided and active tasks, reinforcing a non-binary approach to the question of activity-passivity in perceptual learning and supporting a complex view of the phenomena involved in action-based learning.

An increasing number of research teams are investigating the efficacy of brain-computer interface (BCI)-mediated interventions for promoting motor recovery following stroke. A growing body of evidence suggests that of the various BCI designs, most effective are those that deliver functional electrical stimulation (FES) of upper extremity (UE) muscles contingent on movement intent. More specifically, BCI-FES interventions utilize algorithms that isolate motor signals—user-generated intent-to-move neural activity recorded from cerebral cortical motor areas—to drive electrical stimulation of individual muscles or muscle synergies. BCI-FES (...) interventions aim to recover sensorimotor function of an impaired extremity by facilitating and/or inducing long-term motor learning-related neuroplastic changes in appropriate control circuitry. We developed a non-invasive, electroencephalogram (EEG)-based BCI-FES system that delivers closed-loop neural activity-triggered electrical stimulation of targeted distal muscles while providing the user with multimodal sensory feedback. This BCI-FES system consists of three components: (1) EEG acquisition and signal processing to extract real-time volitional and task-dependent neural command signals from cerebral cortical motor areas, (2) FES of muscles of the impaired hand contingent on the motor cortical neural command signals, and (3) multimodal sensory feedback associated with performance of the behavioral task, including visual information, linked activation of somatosensory afferents through intact sensorimotor circuits, and electro-tactile stimulation of the tongue. In this report, we describe device parameters and intervention protocols of our BCI-FES system which, combined with standard physical rehabilitation approaches, has proven efficacious in treating UE motor impairment in stroke survivors, regardless of level of impairment and chronicity.

Reduced Environmental Stimulation Therapy (REST) alters the balance of sensory input to the nervous system by systematically attenuating sensory signals from visual, auditory, thermal, tactile, vestibular, and proprioceptive channels. Previous research from our group has shown that REST via floatation acutely reduces anxiety and blood pressure while simultaneously heightening interoceptive awareness in clinically anxious populations. Anorexia nervosa (AN) is an eating disorder characterized by elevated anxiety, distorted body representation, and abnormal interoception, raising the question of whether REST might positively (...) impact these symptoms. However, this approach has never been studied in eating disorders and it is unknown whether exposure to REST might worsen AN symptoms. To examine these possibilities we conducted an open-label study to investigate the safety and tolerability of REST in AN. We also explored the impact of REST on affective symptoms, body image disturbance, and interoception. Twenty-one partially weight-restored AN outpatients completed a protocol involving four sequential sessions of REST: reclining in a zero-gravity chair, floating in an open pool, and two sessions of floating in an enclosed pool. All sessions were 90 minutes, approximately one week apart. We measured orthostatic blood pressure before and immediately after each session (primary outcome), in addition to collecting blood pressure readings every 10 minutes during the session using a wireless waterproof system as a secondary outcome measure. Each participant's affective state, awareness of interoceptive sensations, and body image was assessed before and after every session (exploratory outcomes). There was no evidence of orthostatic hypotension following floating, and no adverse events (primary outcome). Secondary analyses revealed that REST induced statistically significant reductions in blood pressure, anxiety and negative affect, heightened awareness of cardiorespiratory but not gastrointestinal sensations, and reduced body image dissatisfaction. The findings from this initial trial suggest that individuals with AN can safely tolerate the physical effects of REST via floatation. Future randomized controlled trials will need to investigate whether these initial observations of improved anxiety, interoception, and body image disturbance can be effectively extended to acutely ill AN populations.

Representations of the fingers are embodied in our cognition and influence performance in enumeration tasks. Among deaf signers, the fingers also serve as a tool for communication in sign language. Previous studies in normal hearing (NH) participants showed effects of embodiment (i.e., embodied numerosity) on tactile enumeration using the fingers of one hand. In this research, we examined the influence of extensive visuo‐manual use on tactile enumeration among the deaf. We carried out four enumeration task experiments, using 1–5 (...) stimuli, on a profoundly deaf group (n = 16) and a matching NH group (n = 15): (a) tactile enumeration using one hand, (b) tactile enumeration using two hands, (c) visual enumeration of finger signs, and (d) visual enumeration of dots. In the tactile tasks, we found salient embodied effects in the deaf group compared to the NH group. In the visual enumeration of finger signs task, we controlled the meanings of the stimuli presentation type (e.g., finger‐counting habit, fingerspelled letters, both or neither). Interestingly, when comparing fingerspelled letters to neutrals (i.e., not letters or numerical finger‐counting signs), an inhibition pattern was observed among the deaf. The findings uncover the influence of rich visuo‐manual experiences and language on embodied representations. In addition, we propose that these influences can partially account for the lag in mathematical competencies in the deaf compared to NH peers. Lastly, we further discuss how our findings support a contemporary model for mental numerical representations and finger‐counting habits. (shrink)

In the last decade, philosophy, neuroscience and psychology alike have paid increasing attention to the study of interpersonal affective touch, which refers to the emotional and motivational facets of tactile sensation. Some aspects of affective touch have been linked to a neurophysiologically specialised system, namely the C tactile system. While the role of this system for affiliation, social bonding and communication of emotions have been widely investigated, only recently researchers have started to focus on the potential role of (...) interpersonal affective touch in acquiring awareness of the body as our own, i.e. as belonging to our psychological ‘self’. We review and discuss recent developmental and adult findings, pointing to the central role of interpersonal affective touch in body awareness and social cognition in health and disorders. We propose that interpersonal affective touch, as an interoceptive modality invested of a social nature, can uniquely contribute to the ongoing debate in philosophy about the primacy of the relational nature of the minimal self.

The goal of the study was to determine which aspects of interpersonal touch interactions lead to a positive or negative experience. Previous research has focused primarily on physical characteristics. We suggest that this may not be sufficient to fully capture the complexity of the experience. Specifically, we examined how fulfilment of psychological needs influences touch experiences and how this relates to physical touch characteristics and situational factors.In two mixed-method studies, participants described their most positive and most negative interpersonal touch experience (...) within a specific time frame. They reported fulfilment of nine needs, affect, intention, and reason for positivity/negativity, as well as the body part(s) touched, location, type of touch, interaction partner, and particular touch characteristics (e.g. humidity).Positive and negative touch experiences shared similar touch types, locations, and body parts touched, but differed in intended purpose and reasons. Overall, the valence of a touch experience could be predicted from fulfilment of relatedness, the interaction partner and initiator, and physical touch characteristics. Positive affect increased with need fulfilment, and negative affect decreased.The results highlight the importance of relatedness and reciprocity for the valence of touch, and emphasise the need to incorporate psychological needs in touch research.

It remains controversial whether touch is a truly spatial sense or not. Many philosophers suggest that, if touch is indeed spatial, it is only through its alliances with exploratory movement, and with proprioception. Here we develop the notion that a minimal yet important form of spatial perception may occur in purely passive touch. We do this by showing that the array of tactile receptive fields in the skin, and appropriately relayed to the cortex, may contain the same basic informational (...) building blocks that a creature navigating around its environment uses to build up a perception of space. We illustrate this point with preliminary evidence that perception of spatiotemporal patterns on the human skin shows some of the same features as spatial navigation in animals. We argue (a) that the receptor array defines a ‘tactile field’, (b) that this field exists in a minimal form in ‘skin space’, logically prior to any transformation into bodily or external spatial coordinates, and (c) that this field supports tactile perception without integration of concurrent proprioceptive or motor information. The basic cognitive elements of space perception may begin at lower levels of neural and perceptual organisation than previously thought. (shrink)

The last decade has seen great progress in the study of the nature of crossmodal links in exogenous and endogenous spatial attention . Exogenous spatial cuing studies of human crossmodal attention and multisensory integration. In C. Spence, & J. Driver , Crossmodal space and crossmodal attention . Oxford, UK: Oxford University Press.], for a recent review). A growing body of research now highlights the existence of robust crossmodal links between auditory, visual, and tactile spatial attention. However, until recently, studies (...) of exogenous and endogenous attention have proceeded relatively independently. In daily life, however, these two forms of attentional orienting continuously compete for the control of our attentional resources, and ultimately, our awareness. It is therefore critical to try and understand how exogenous and endogenous attention interact in both the unimodal context of the laboratory and the multisensory contexts that are more representative of everyday life. To date, progress in understanding the interaction between these two forms of orienting has primarily come from unimodal studies of visual attention. We therefore start by summarizing what has been learned from this large body of empirical research, before going on to review more recent studies that have started to investigate the interaction between endogenous and exogenous orienting in a multisensory setting. We also discuss the evidence suggesting that exogenous spatial orienting is not truly automatic, at least when assessed in a crossmodal context. Several possible models describing the interaction between endogenous and exogenous orienting are outlined and then evaluated in terms of the extant data. (shrink)

The philosophical theory of scientific explanation proposed here involves a radically new treatment of causality that accords with the pervasively statistical character of contemporary science. Wesley C. Salmon describes three fundamental conceptions of scientific explanation--the epistemic, modal, and ontic. He argues that the prevailing view is untenable and that the modal conception is scientifically out-dated. Significantly revising aspects of his earlier work, he defends a causal/mechanical theory that is a version of the ontic conception. Professor Salmon's theory furnishes a robust (...) argument for scientific realism akin to the argument that convinced twentieth-century physical scientists of the existence of atoms and molecules. To do justice to such notions as irreducibly statistical laws and statistical explanation, he offers a novel account of physical randomness. The transition from the "reviewed view" of scientific explanation to the causal/mechanical model requires fundamental rethinking of basic explanatory concepts. (shrink)

Dual process accounts of affective learning state that the learning of likes and dislikes reflects a learning mechanism that is distinct from the one reflected in expectancy learning, the learning of signal relationships, and has different empirical characteristics. Affective learning, for example, is said not to be affected by: (a) extinction training; (b) occasion setting; (c) cue competition; and (d) awareness of the CS-US contingencies. These predictions were tested in a series of experiments that employed simple Pavlovian conditioning procedures. Neutral (...) visual pictures of geometric shapes, or tactile conditional stimuli (CS) were paired with aversive electrotactile unconditional stimuli (US). Dependent measures were physiological (skin conductance, blink startle modulation) or verbal (US expectancy, on-line and off-line ratings of CS pleasantness). Different combinations of these dependent measures were employed across different experiments in an attempt to assess affective and expectancy learning simultaneously. Changes in CS pleasantness as indexed by ratings or blink startle modulation were readily observed. However, contrary to the predictions from dual-process accounts, results indicated that acquired CS unpleasantness is subject to extinction, occasion setting, cue competition, and not found in absence of CS-US contingency awareness.

1. The most important aspect of touch is its relation to time and space, a relation which is established by the movement of touching itself. Referring to the ideas of E. Straus, the distinction between touching and being touched is elaborated in light of experiments done by us with animals. 2. Touching is: being in one's own limits and at the same time going beyond these limits, a situation in which the touched object is felt at the same time as (...) a "Gegenstand" and as "Mit-seiend." "Pour le tactile, c'est l'être à deux qui se place au premier rang" . The awareness of being by the sense of touch is particularly poignant in the case of touching oneself, which is an exceptional unity of the active and the passive state of mind. 3. The tactile recognition of form also presents a dialectic of activity and passivity, a dialectic which takes place in the form of a development which conquers time, and this after a scheme produced during the act of grasping itself. We refer to the studies of V. von Weizsäcker on the "Gestaltkreis." We must also remember the basic restlessness of the hand, which becomes lasting in the play of the hand with an object. 4. The hand can hold an object. In doing so a schematic tactile image is given, an image which functions as a hypothesis or as an organizing principle of the proleptic development of further tactile exploration. The phenomenological analysis of touch with the hand appears as a prefiguration of thought by synthetic judgments. Thus, it is true, as Herder remarked, and as Gold-stein and Merleau-Ponty confirmed, that perception by man and spiritual existence are identical. 5. Referring to the research of Révèsz and Palagyi, the real nature of the tactile world is anlyzed. Tactile exploration is done according to a real development, during which take place anticipatory and retrospective determinations which assure the continuity of the event and its meaning. Tactile perception permits description of the continuous unity of the discontinuous phases which we can state objectively "as if" expectation and memory, preliminary judgments and their checking, conceptual fixations and corrections had been put to work. 6. Important is the affective and emotional aspect of tactile impressions and their connection with inter-human relationships. 7. By touch, man establishes in a "feeling" way a personal relationship with the matter of things, which is hidden to the distance senses. This participation has a double aspect. It is like the birth of a "mood," of a "Befindlichkeit," but at the same time it is the active point of departure of a "feeling," of an "understanding," of an "inner grasp," of a being moved, of a being struck by the touched object which is then in our presence as a real "quale," as a material object, as a being in itself. We remember the proper nature of the caress, by which the "being together" of the caressed object complements that of the active caresser. The usual concepts by means of which, in practical and gnostic life, the most important tactile qualities are indicated intend to refer us to the characteristics of the things which take up space in the geometric world and in objectively measurable space, and on which is founded our natural orientation. We remember von Hornborstel's research on the intermodal characteristics of tactile impressions. These show us how a "knowledge" which accompanies perception can change an impression of feeling. The affective relationship, determined by a shaded "knowledge" and by a system of values, changes tangible reality, the substantiality of the body, of the "flesh." This affective change of matter, this "phenomenal transsubstantiation," easily becomes a reality in connection with objects of which we know that they belong or did belong to someone. The meaning which a thing has changes the matter of the object, an object which precisely by the touch is present "in the flesh." This is illustrated more precisely by the phenomena of fetishism, and by simple experiences of daily life. If we look for an anthropological point of view from which touch, of which the hand realizes the point of view will have to be attempted starting from the unimaginable certitude that the ontological unity of nature and spirit is in man the reality of a possible participation, a participation which, in our existence, is only indicated. The "restlessness" of the hand, never fulfilled and always searching, which we noted, is the human token of our concrete existence. Thus touch shows us what Valery remarked about the mind: "The mind is at the mercy of the body, as the blind are at the mercy of the seeing.". (shrink)

Le lecteur attentif du traité De l'âme et des Parva naturalia sera troublé par une ambiguïté profonde sous-jacente à toute la longue discussion de la perception dans ces œuvres. Il s'agit de savoir si la théorie d'Aristote se veut une théorie d'ordre physiologique prise au sens littéral, ou si elle se veut plutôt une théorie métaphysique, qui doit donc être prise au sens métaphorique. La doctrine en question se résume comme suit: un sens, en percevant, reçoit en lui-même la forme (...) de l'objet perçu sans la matière. Selon l'interprétation physiologique, il faudrait entendre par là que lorsqu'un homme regarde, sent, et écoute un âne, par exemple, il y aurait dans un endroit près de son cœur – dans l'organe central de la perception – une petite poupée d'âne qui braie et qui pue. Cette poupée serait reconstruite dans l'organe central à partir des composants sensoriels qui y seraient amenés des organes spéciaux: de l'œil la forme et la couleur, de l'organe olfactif l'odeur, et, de l'oreille le son. Un chirurgien qui ouvrirait la poitrine de l'homme percevant y verrait la poupée, la sentirait, et l'entendrait. La poupée serait comme celle de la princesse Leia dans le film Star Wars, à cette différence qu'elle jouirait non seulement de propriétés visuelles et auditives, mais aussi de propriétés olfactives et tactiles.

_Rhetoric_ is the sixth volume in The New Hackett Aristotle series, a series featuring translations, with Introductions and Notes, by C. D. C. Reeve, Delta Kappa Epsilon Distinguished Professor of Philosophy at The University of North Carolina at Chapel Hill. The series will eventually include all of Aristotle's works.

Initially, we perceive an indefinite extension imprecisely, a spread C ; this perception can be visual, aural, or tactile.

This section contains four original articles addressing the matters of interaction, coexistence and representation of the human senses in various historical and cultural contexts. The multisensory experience of the world in relations to the past, the present and the future constitutes the main theme of the selected articles. The authors analyze how, in various cultural texts and historical moments, human experience was depicted through the prism of sensory perception, sometimes combined with sensory memory and the powerfulness/powerlessness of the (non)human corporeality. (...) The authors analyze a variety of historical and cultural sources to answer the question of the impact of multisensory experience on our view of the world: in the past, the present and the future. Nina C. Rastinger in her article “Capturing Extraordinary Multisensory Experiences in Writing: Reports on Natural Disasters in an 18th Century Newspaper Corpus” deals with written representations of natural disasters, which constitute extraordinary multisensory experiences, in historical newspaper texts. Natalia Giza in her study “Multisensuality in the Satirical Prints of the Georgian Era in England” shows how sensory perception enhanced visual humor in the satirical prints of Georgian England, examining how English caricaturists used various sensory elements such as sight, sound, smell, taste, and touch. Jules Sebastian Skutta in his paper “Tactile Vision and Othering: Ethnographic Engagements and Racial Differentiations in 19th Century Travelogues” demonstrates on the basis of ethnographic travelogues from German East Africa and from the time of German colonial rule that the transmission, emergence, and dissemination of features of racial differentiation are based on the interplay of different sensory perceptions. Finally, Bartosz Mroczkowski, in the article entitled “Designing the Future Through Touch” focuses on the sense of touch in the process of designing the future. The aforementioned articles illustrate that multisensuality is a multidimensional concept that requires a thorough analysis from different academic perspectives and with the use of various methodological approaches.

1. L'aspect le plus important du toucher est sa relation au temps et à l'étendue, relation constituée par le mouvement même du toucher. En référence aux conceptions de E. Straus, on expose la distinction entre le toucher et l'être-touché à la lumière d'expériences faites par nous avec des animaux. 2. Le toucher est un être-dans-les-limites-propres et en même temps un franchissement de ces limites, être par lequel l'objet touché est éprouvé à la fois comme „Gegenstand” et comme „Mitseiend”. „Pour le (...) tactile, c'est l'être à deux qui se place au premier rang.” L'affirmation de l'être par le sens du toucher est saisissante dans le cas du se-touchersoi-même, qui est une union exceptionnelle d'activité et de passivité. 3. La reconnaissance tactile de la forme présente elle aussi une dialectique d'activité et de passivité, dialectique qui procède sous la forme d'un développement surmontant le temps, et cela à partir d'un schéma produit dans l'acte même de préhension. On renvoie aux études de V. von Weizsäcker sur le „Gestaltkreis”. Il faut se rappeler aussi l'inquiétude primaire de la main, qui dans le jeu de la main avec un objet devient perdurante. 4. La main peut enserrer un objet. En ce faisant une image schématique tactile est donnée, image qui fonctionne comme hypothèse ou comme principe organisateur du développement prolèptique de l'exploration tactile ultérieure. L'analyse phénoménologique du toucher avec la main se révèle comme une préfiguration de la pensée par jugements synthétiques. Il est donc vrai, comme le remarquait Herder et comme le confirmaient Goldstein et Merleau-Ponty, que la perception telle que l'homme l'effectue et l'existence spirituelle sont identiques. 5. En se référant aux recherches de Révèsz et de Palagyi, on analyse le caractère propre du monde tactil. L'exploration tactile procède selon un véritable développement, donnant lieu à des déterminations anticipatives et rétrospectives qui assurent la continuité de l'événement et de son sens. La perception tactile permet de décrire l'unité continue des phases discontinues objectivement constatables, „comme si” attente et souvenir, jugements provisoires et vérification, fixations conceptuelles et corrections étaient mises en œuvre. 6. Important est l'aspect affectif et émotif des impressions tactiles et leur rapport aux relations interhumaines. 7. Par le toucher l'homme se trouve d'une manière „sensible” en relation personnelle avec cette matérialité des choses qui demeure cachée aux sens-à-distance. Cette participation a un double aspect. Elle est comme le surgissement d'un „état d'âme”, une '‚Befindlichkeit”, mais en même temps elle est le point de départ actif d'un sentir, d'un „comprendre”, d'un „saisir par le dedans”, d'un être-ému, d'un être-frappé par l'objet touché qui se rend présent comme un „quale” propre, comme une matière, comme un être-en-soi. On rappelle le caractère propre du caresser, par lequel l'„être à deux” de l'objet caressé devient complémentaire avec celui du caressant actif. Les concepts usuels par le moyen desquels, dans la vie pratiquement et gnostiquement vécue, sont indiquées les qualités tactiles les plus importantes, ont comme but de nous référer aux propriétés des choses qui prennent place dans le monde géométrique et dans l'espace objectivement mesurable et qui fondent notre orientation naturelle. On rappelle les recherches de von Homborstel au sujet des propriétés internodales des impressions tactiles. Celles-ci nous montrent comment un „savoir” qui accompagne ta perception peut changer une impression sensible. La relation affective, déterminée par un „savoir” nuancé et par un système de valeurs, change la réalité tangible, la substantialité du corps, de la „chair”. Ce changement affectif de la matière, cette „transsubstantiation phénoménale” peut se réaliser facilement par rapport à des objets dont nous savons qu'ils appartiennent ou ont appartenu à quelqu'un. La signification qu'a une chose change la matière de l'objet, objet qui, précisément par le toucher, se rend présent „en chair et en os”. On illustre ceci avec plus de précision grâce aux phénomènes du fétichisme et grâce à de simples expériences de la vie courante. Si nous cherchons un point de vue anthropologique à partir duquel le toucher, dont la main réalise les possibilités, peut prendre un sens, une approche d'un tel point de vue devra s'effectuer à partir de la certitude non-représentable que l'unité ontique de la nature et de l'esprit est dans l'homme la réalité d'une participation possible, participation qui, dans notre existence, n'est qu'indiquée. L'„inquiétude” de la main jamais remplie et toujours chercheuse que nous avons remarquée, est le signe humain de notre existence concrète. Ainsi le toucher nous montre ce que Valéry remarquait à propos de l'esprit : „L'esprit est à la merci du corps, comme les aveugles sont à la merci des voyants.”. (shrink)

The properties of secondary qualities have recently become an object of interest again in analytic philosophy; it is generally assumed that secondary qualities - in the mind at least - tend to be irreducible to the physical: taste, smell, color perception, the aural, & the tactile all seem to be more subjectively perceived than most other qualities. This is shown to present such topics as realism vs anti-realism, description, & truth-value with a series of problems, which are then discussed. (...) The standard literature (S. A. Kripke, D. M. Armstrong, & C. McGinn) is reviewed; it is concluded that, at least for color perception, a dispositional analysis is somewhat satisfactory; secondary qualities are ubiquitous. 7 References. A.

In this essay, I examine Arthur C. Danto s highly influential thesis that Andy Warhols Brillo Box ends art by obviating the need for art object to differ sensually from ordinary object. Coining the term Co-aesthesis, I demonstrate that it is only by improperly applying Extensionalism that anyone is able to make the claim that the Brillo Box is substantively equivalent to a Brillo Box in the first place: if we just work harder to coordinate the various visual, tactile (...) and contextual data striking our sensorium, we can arrive at a very different spot than the place from which we witness art ending — especially when we consider the revelations about multi-dimensionality in the realm of physics. To help make my point, I use Italian philosopher Tiziana Andina’s recent book Arthur Danto: Philosopher of Pop and her interpretation that, after Danto, a sensual Aesthetics parts company from a conceptual and sensually inert Philosophy of Art.

Investigates the resolution of contradictions and ambiguous derogations in a code, by means of the imposition of partial orderings. Although formulated as a study in the logic of norms, it provided the initial ideas for work on the logic of theory (or belief) change, developed by the authors in a series of papers by the authors and Peter Gardenfors beginning in 1985.

Aristotle's treatise De Interpretatione is one of his central works; it continues to be the focus of much attention and debate. C. W. A. Whitaker presents the first systematic study of this work, and offers a radical new view of its aims, its structure, and its place in Aristotle's system, basing this view upon a detailed chapter-by-chapter analysis.By treating the work systematically, rather than concentrating on certain selected passages, Whitaker is able to show that, contrary to traditional opinion, it forms (...) an organized and coherent whole. He argues that the De Interpretatione is intended to provide the underpinning for dialectic, the system of argument by question and answer set out in Aristotle's Topics; and he rejects the traditional view that the De Interpretatione concerns the assertion and is oriented towards the formal logic of the Prior Analytics. In doing so, he sheds valuable new light on some of Aristotle's most famous texts. (shrink)

C. Stephen Evans explains and defends Kierkegaard's account of moral obligations as rooted in God's commands, the fundamental command being `You shall love your neighbour as yourself'. The work will be of interest not only to those interested in Kierkegaard, but also to those interested in the relation between ethics and religion, especially questions about whether morality can or must have a religious foundation. As well as providing a comprehensive reading of Kierkegaard as an ethical thinker, Evans puts him into (...) conversation with contemporary moral theorists. Kierkegaard's divine command theory is shown to be an account that safeguards human flourishing, as well as protecting the proper relations between religion and state in a pluralistic society.

Is there such a thing as natural knowledge of God? C. Stephen Evans presents the case for understanding theistic arguments as expressions of natural signs in order to gain a new perspective both on their strengths and weaknesses. Three classical, much-discussed theistic arguments - cosmological, teleological, and moral - are examined for the natural signs they embody. At the heart of this book lie several relatively simple ideas. One is that if there is a God of the kind accepted by (...) Christians, Jews, and Muslims, then it is likely that a 'natural' knowledge of God is possible. Another is that this knowledge will have two characteristics: it will be both widely available to humans and yet easy to resist. If these principles are right, a new perspective on many of the classical arguments for God's existence becomes possible. We understand why these arguments have for many people a continued appeal but also why they do not constitute conclusive 'proofs' that settle the debate once and for all. Touching on the interplay between these ideas and contemporary scientific theories about the origins of religious belief, particularly the role of natural selection in predisposing humans to form beliefs in God or gods, Evans concludes that these scientific accounts of religious belief are fully consistent, even supportive, of the truth of religious convictions.

_Verificationism_ is the first comprehensive history of a concept that dominated philosophy and scientific methodology between the 1930s and the 1960s. The verificationist principle - the concept that a belief with no connection to experience is spurious - is the most sophisticated version of empiricism. More flexible ideas of verification are now being rehabilitated by a number of philosophers. C.J. Misak surveys the precursors, the main proponents and the rehabilitators. Unlike traditional studies, she follows verificationist theory beyond the demise of (...) positivism to examine its reappearance in the work of modern philosophers. Most interestingly, she argues that despite feminism's strenuous opposition to positivism, verificationist thought is at the heart of much of contemporary feminist philosophy. _Verificationism_ is an excellent assessment of a major and influential system of thought.

A critical and detailed introduction to Kant's philosophy, with particular reference to the Critique of Pure Reason. Since Broad's death there have been many publications on Kant but Broad's 1978 book still finds a definite place between the very general surveys and the more specialised commentaries. He offers a characteristically clear, judicious and direct account of Kant's work; his criticisms are acute and sympathetic, reminding us forcefully that 'Kant's mistakes are usually more important than other people's correctitudes'. C.D. Broad was (...) Knightsbridge Professor of Moral Philosophy at Cambridge from 1933 to 1953, and this book is based on his undergraduate lectures on Kant. Broad died in 1971 and Dr Lewy has since edited the book for publication. (shrink)

Most whistleblowers talk as if they never had a choice about whether to blow the whistle. This doesn't mean they acted suddenly, or impulsively, only that they believe they could not have done otherwise. Trying to make sense of this near universal answer to the question "Why did you do it?" the essay draws on narrative theory. Narrative theory distinguishes between actant and sender—that is, between actor and his or her values. This distinction helps to explain what it means to (...) face a difficult choice over something about which one feels one never had a choice. (shrink)

Part of the draw of athletics is its straightforwardness. There are nuances to competitions to make them more sporting contests, but at the end of a long jump competition whomever records the longest jump should win. Unfortunately, a recent rule-change at the highest level of the sport – the “Final 3” format – undermined this simplicity for the horizontal jumps and the throws for some of the 2020 and much of the 2021 seasons. While fortunately this rule was largely reverted (...) within days of the initial submission of this paper, it’s still valuable to critically evaluate why such a rule is problematic so as to better understand of the value of sporting competitions and give guidance on future rule changes, be they in athletics or other sports. To that end, we will be drawing from the literature on the purpose and value of competitions and coupling that with simulations based on data from actual top-tier long jump competitions to show that the Final 3 format makes for significantly worse competitions than the standard format.
