Because philosophical reflections on touch usually start from our ability to perceive properties of objects, they tend to overlook features of touch that are crucial to correct understanding of tactual perception. This paper brings out these features and uses them to develop a general reconception of the sense of touch. I start by taking a fresh look at our ability to feel, in order to reveal its vital role. This sheds a different light on the skin's (...) perceptual potential. While it is commonly observed that tactile experiences have two intentional objects, an external object and one's own body, I will advance a more accurate alternative: in tactile experiences, one becomes aware of what one's body undergoes. This alternative not only fits better with tactility's vital role; it is also key to explaining how active touching provides for a unique contribution to our perceptual relation to material objects. By thus connecting tactility's vital role to the way we rely on touch while manipulating objects, this essay offers a cross-sectional survey of our tactile powers that reveals the interplay between sensing and touching.

From posture to piety, from manicure to magic, the book discovers touch in a critical period of its historical development, in anatomy and society.

Touch is the first sense to develop in the womb, yet often it is overlooked. The Senses of Touch examines the role of touching and feeling as part of the fabric of everyday, embodied experience. -/- How can we think about touch? Problems of touch and tactility run as a continuous thread in philosophy, psychology, medical writing and representations in art, from Ancient Greece to the present day. Picking through some of these threads, the book (...) ‘feels’ its way towards writing and thinking about touch as both sensory and affective experience. -/- Taking a broadly phenomenological framework that traces the tactility from Aristotle through the Enlightenment to the present day, it examines the role of touch across a range of experiences including aesthetics, digital design, visual impairment and touch therapies. The Senses of Touch thereby demonstrates the varieties of sensory experience, and explores the diverse range of our ‘senses’ of touch. (shrink)

The paper posits a relationship between the sensory modality of touch, including a sense of active movement, and early modern knowledge of active powers in nature. It seeks to appreciate the strength and appeal of knowledge built on the active-passive distinction, including that which was retrospectively labeled animist. Using statements by Descartes, Hobbes, Locke, Spinoza, Leibniz, and Stahl, rather than detailed new readings of texts, the paper asks whether scholars drew on phenomenal, or conscious, awareness of activity as (...) effort encountering resistance when they reasoned about activity in the world. How were there relations and analogies between descriptions of psyche’s relation to body, of the relation of living forces to matter, of relations among material objects, of God’s relationship to His creation, and of relations involving causal agency generally? It is possible to understand what were later called animistic theories as belonging to the mainstream of the new natural philosophy, not to a residue of unscientific argument. Early modern theories of active and vital powers cannot be dismissed because they were based, in error, on mere analogy to human action. Rather, they had a central position in reasoning grounded in phenomenal awareness of action-resistance when a person is “in touch.”. (shrink)

In recent philosophy of mind, a series of challenging ideas have appeared about the relation between the body and the sense of touch. In certain respects, these ideas have a striking affinity with Husserl’s theory of the constitution of the body. Nevertheless, these two approaches lead to very different understandings of the role of the body in perception. Either the body is characterized as a perceptual “organ,” or the body is said to function as a “template.” Despite its (...) focus on the sense of touch, the latter conception, I will argue, nevertheless orients its understanding of tactual perception toward visual objects. This produces a distorted conception of touch. In this paper, I will formulate an alternative account, which is more faithful to what it is like to feel. (shrink)

Aristotle’s treatment of tactility is at odds with the hierarchical order of psyche’s faculties. Touching is the commonest and lowest power; it is possessed by all sentient beings; thinking is, on the contrary, the highest faculty that distinguishes human beings. Yet, while Aristotle maintains against some of his predecessors that to think is not to sense, he nevertheless posits a causal link between practical intelligence and tactility and even describes noetic activity as a certain kind of touch. This (...) essay elucidates Aristotle’s analysis of the sense of touch in De anima and argues that tactility provides a paradigm for sensitivity in general and in particular for the reflexivity of sensation whereby the senses disclose not only what they are sensing but also that they are sensing. This feature, it is argued, has epistemological and ontological consequences. The sense of touch testifies to the physical presence of material beings and provides an empirical verification of substance’s essential feature, namely, self-reference. (shrink)

This essay explores the central place of Aristotle’s views of the sense of touch within his empiricist epistemology and general physical theory. It argues that Aristotle was not committed to a ‘literalist’ view of the nature of sensory representation, according to which an organ literally becomes ‘like’ the said object. It suggests an interpretation of Aristotle’s defence of the objectivity of tactile representation, which shows a deep and complex link between his theory of sense-knowledge and his project (...) of scientific explanation.

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)

This paper on Aristotle’s De Amilla attempts to understand the treatise as a unified whole---a unity, it may be argued, that is only as problematic as is the unity of the soul of which it speaks. Aristotle’s treatise on the soul must strike its reader as being all too perplexing, and the subject of touch in particular seems to arouse such perplexity. But Aristotle would have it that “in our inquiry into the soul, in going forward, we must be (...) thoroughly perplexed” (403b20). Touch, as a locus of perplexity in the De Amina, thus seems to provoke the kind of forward motion that leads to the human soul’s knowledge of itself. As such a locus of perplexity, I hope to show, the discussion of touch serves as a thread that provides the seams needed to tie the text together as an integrated whole. By focusing on Aristotle’s account of the faculty of touch, I believe I have come close to capturing the essence of what Aristotle means by entelecheia. Soul understood as an entelecheia amounts to the location of the soul’s highest possibilities in the activity of learning rather than knowing. Aristotle is much more Socratic than he might at first appear. (shrink)

This article seeks to find attitudes and judgments elite Romans made based on a person’s bed. It culls written sources from a diverse range of genres to argue that elite Roman men saw beds as transformative and reflective items. Through long-lasting and frequent contact, a bed’s qualities seeped into bodies and characters. Consequently, as a powerful part of the built environment, beds could strengthen or weaken soldiers as well as help or harm a person’s health. Furthermore, beds’ transformative power meant (...) elite Romans thought where a man slept revealed who he was: his social status, moral fiber, and civilization. In short, beds marked a person’s identity. Examining how Roman elites conceptualized beds informs us on the larger issue of the history of the body, in general, and the sense of touch, in particular. Scholarship on the history of touch tends not analyze the effects of sustained and repetitive contact with a mundane object. (shrink)

This thesis vindicates the common-sense intuition that touch is more objective than the other senses. The reason why it is so, it is argued, is that touch is the only sense essential of the experience of physical effort, and that this experience constitutes our only acquaintance with the mind-independence of the physical world. The thesis is divided in tree parts. Part I argues that sensory modalities are individuated by they proper objects, realistically construed. Part II argues (...) that the proper objects of touch are pressures and tensions, defined as pairs of real and antagonist forces. Part III argues that experiences of pressures are an essential part of the experience of physical effort and that the experience of physical effort (which amounts to the experience of resistance to our will), constitutes our only immediate access to the mind-independence of the physical world.

The aim of this paper is to give a description of the objects of the sense of touch. Those objects, it is argued, are forces, rather than flesh deformation, solidity or weight. Tangible forces, basically tensions and pressures, are construed as symmetric and non-spatially reducible causal relations. Two consequences are drawn: first, the perception of heat and cold falls outside the sense of touch; second, muscular sense (together with a large part of proprioception) falls inside (...) the sense of touch.

To form a coherent percept of the environment, our brain combines information from different senses. Such multisensory integration occurs in higher association cortices; but supposedly, it also occurs in early sensory areas. Confirming the latter hypothesis, we unequivocally demonstrate supra-additive integration of touch and sound stimulation at the second stage of the auditory cortex. Using high-resolution fMRI of the macaque monkey, we quantified the integration of auditory broad-band noise and tactile stimulation of hand and foot in anaesthetized animals. Integration (...) was found posterior to and along the lateral side of the primary auditory cortex in the caudal auditory belt. Integration was stronger for temporally coincident stimuli and obeyed the principle of inverse effectiveness: greater enhancement for less effective stimuli. These findings demonstrates that multisensory integration occurs early and close to primary sensory areas and—because it occurs in anaesthetized animals—suggests that this integration is mediated by preattentive bottom-up mechanisms.

In this essay, I review Matthew Fulkerson's The First Sense: A Philosophical Study of the Sense of Touch. In this first philosophical book on the sense of touch, Fulkerson provides an account of the nature and content of tactual experience. Central to Fulkerson's view is the claim that exploratory action plays a fundamental role in touch. In this review, I put pressure on two of his arguments: the argument that tactual experience is unisensory and (...) the argument that tactual experience does not depend on explicit bodily awareness.

The sense of touch provides us knowledge of two kinds of events. Tactile sensation (T) makes us aware of events on or just below the skin; haptic perception (H) gives us knowledge of things outside the body with which we are in contact. This paper argues that T and H are distinct experiences, and not (as some have argued) different aspects of the same touch-experience. In other words, T ≠ H. Moreover, H does not supervene on T. (...) Secondly: In T, we are aware of immanent, phenomenal qualities; in H, we come to know of transcendent qualities in things that exist independently of ourselves. Finally: T is non-spatial; it is indexed by parts of the body, but not by position in space. H, by contrast, is spatial. This brings to mind Kant’s contention that things are presented as existing objectively when they are represented spatially. (shrink)

This article brings together two debates in contemporary political philosophy: on the one hand, the dispute between the distributive and relational approaches to equality and, on the other hand, the field of intergenerational equality. I offer an original contribution to the second domain and by doing so, I inform the first. The aim of this article is thus twofold: (1) shedding some light on an under-researched and yet crucial question – ‘which inequalities between generations matter?’ and (2) contributing to a (...) far-reaching debate that touches upon the nature of egalitarianism. After showing that there are two key problems that fall within the scope of intergenerational equality – questions of justice between age groups and questions of equality between birth cohorts – I argue that, contrary to what the default distributive view (complete lives egalitarianism) states, some inequalities between age groups matter independently of their diachronic impact, and so partly for relational reasons. I argue that, even if we are distributive egalitarians, we must endorse the relational egalitarian conception to successfully make sense of some inequalities between age groups. I infer from this both that the putative view that the ‘relational’ conception of equality can be redescribed as distributive must be rejected and that the distributive view requires supplementation (but not necessarily displacement) by the relational view.

This essay explores Aristotle’s discovery of touch as the most universal and philosophical of the senses. It analyses his central insight in the De Anima that tactile flesh is a “medium not an organ,” unpacking both its metaphysical and ethical implications. The essay concludes with a discussion of how contemporary phenomenology—from Husserl to Merleau-Ponty and Irigaray—re-describes Aristotle’s seminal intuition regarding the model of “double reversible sensation.”.

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)

This paper is an ethnographic examination of the early social life of a project to map Costa Rica’s aquifers using LandSat imagery and a specialized algorithm. The project aims to make subterranean formations accessible for public agencies mediating recent environmental conflicts over underground water, which have been diagnosed as the country’s first “water war.” I analyze the presentation to the public of this project and the technology it uses to show how vision and touch are conceptual resources that people (...) use to describe the technicalities of satellite imagery. Attending to the semiotic and technical power of vision and touch requires a nonessentialist understanding of the senses. It requires moving away from a narrow understanding of sensing as embodied, phenomenological practice. Focusing on the role of texture as that which operates in the interstices of vision and touch, I propose going beyond panoptic imaginaries in order to grasp the diverse social lives that technologies such as satellite imaging have.

In his experimental studies on tactile recognition, the German neurologist Kurt Goldstein observes a peculiar ‘twitching movement’ of the body in neurologically impaired patients suffering from mind-blindness. Drawing on Goldstein’s interpretation of these bodily movements as kinaesthetic reactions, the present article advances a symmetrical conception of tactility that relocates the bipolarity of the sense of touch within the human body. In line with this symmetrical approach, the kinaesthetic reactions will be construed as tactile self-activation or self-touch of (...) the body and conceptualized, following Michael Polanyi’s epistemological notion, as the ‘tacit dimension of touch’. Combining neuropathological aspects with a media theoretical and epistemological trajectory, this article aims at re-evaluating the centrality of the registers of the sense of touch as the fundamental ground for grasping the world in its concrete encounters as well as in its symbolic abstractions.

In lieu of an abstract, here is a brief excerpt of the content:The Place of Touch in the ArtsChristopher Perricone (bio)IntroductionIn Breughel's great picture, The Kermess, the dancers go round, they go round and around, the squeal and the blare and the tweedle of bagpipes, a bugle and fiddles tipping their bellies (round as the thick- sided glasses whose wash they impound) their hips and their bellies off balance to turn them. Kicking and rolling about the Fair Grounds, swinging (...) their butts, those shanks must be sound to bear up under such rollicking measures, prance as they dance In Breughel's great picture, The Kermess.1"The Dance" written by William Carlos Williams in 1944 is one of my favorites. Williams gives us a feel for that life of the kermess (a carnival) in his poem through Breughel's picture, as it were three times removed from the event itself. Of course, unlike Plato, I would argue that the vitality of the kermess is not lost in the poem; it is actually enhanced by a subtle sleight of hand. The poem is not primarily about Breughel's picture. It is about dance, about the dancers who go round, their squeal, the crude music, its rollicking measures, the dancers kicking and rolling and swinging, their hips, bellies, and butts. Reading this poem, I "see" those ordinary folk of Breughel's great picture. I "hear" their music. I "move" to their dance. The poem seems a condensation, a summary of the fine arts. Perhaps the poem is about poetry's power to reinvigorate imaginatively what we hear and see. Perhaps I think of festivities at which I have danced, how such festivities are essential to the human experience. Perhaps William Carlos Williams in 1944, World War II coming to a close, was anticipating similar good times.Tactile ValuesThe fine arts do much to educate our senses. One need only recall the many essays and books written on art, on how to look and hear, how various [End Page 90] critics draw our attention to the power of imagery and song. The well-formed visual and auditory sensations we gain from the arts are, as it were, the melody of those experiences. They are the pictures we store away, the tunes we whistle. However, here I want to draw attention to an overlooked sense—touch. I want to argue that touch is the bass line to the melody of sight and hearing in the arts, that is, that touch keeps the artwork coherent and grounded.This is an old idea. Bernhard Berenson had the idea when he was examining the painters of the Italian Renaissance. In a sense this article is a resurrection of Berenson's idea of "tactile values." Berenson was on to something both about painting and about the arts in general. However, he lacked the scientific evidence about touch and its role in human relationships needed to develop his idea of tactile values to any great extent.The idea of tactile values is first mentioned at the beginning of the essay "The Florentine Painters." Berenson is discussing the art of Giotto. However, prior to plunging into his subject, he says that we need to know what is essential to figure painting before we can appreciate its real value. What is essential are the "tactile values" we give to our retinal impressions, "a test of reality."2 Painting stimulates touch in order for it to stimulate our "tactile imagination."3 Giotto was a genius in stimulating the tactile imagination. Like other medieval masters, Giotto was a fine story teller and had great compositional skills. However, unlike Giotto, other medieval masters "never painted a figure which has artistic existence."4 Giotto's predecessors crafted "highly elaborate, very intelligible symbols, capable, indeed, of communicating something, but losing all higher value the moment the message is delivered."5 If such medieval symbols communicated anything at all, it was only some residue of what one might touch; whatever reality those symbols might have possessed was virtually eviscerated by the artists' emphasis on form and cognitive content. Giotto's predecessors were driven merely by ideas and, one might add, not altogether consistent and coherent ones. On the contrary, Giotto's work seemed to... (shrink)

Engaging with the specific ways current media technologies interact with, or directly access the human body, we suggest developing a ‘symmetrical’ theory of touch. Critically referring to Bruno Latour’s invocation of ‘symmetrical anthropology’, we reconsider tactile agency as ‘technological agency’, arguing that the concept of touch – traditionally viewed as an exclusively human ability – should be extended to non-human actors and analysed in view of the cultural logic of capitalism. Its systematic focus, then, is on the productive (...) intersections and contact zones between biology and technology: from phenomena of non-human touch in industrial production to the material touching taking place in the instrumental grasp on the living in the 19th-century physiological laboratories and the invisible operations of tracing, tracking and sensing taking place in the technological milieus of today’s environments. In highlighting the tactile dimension of digital modernity and its economic genealogies, this article aims to advance a combined concept of human and non-human touch which provides a crucial angle for reconsidering bodies and technologies in the age of ubiquitous computing.

The importance of touch to mammalian survival and well-being cannot be overstated. The capacity for action depends on the sense of touch, which is a necessary feature of an animal’s being-in-the-world (O’Shaughnessy, 1989, pp. 38–39). Interpersonal touch has been shown to be an important part of human welfare, including disease prevention and treatment (see Field, 2001 for review). Throughout a mammal’s lifespan, social relation- ships are also mediated by touch behavior (see Thayer, 1986 for review). (...) Given these facts, the sense of touch is relevant to a variety of topics in psychology, including but not limited to: perception, action, nonverbal behavior, relationships, development, emotion, and health.

This paper offers theoretical explanations for why “guided touch” or manual touch with verbal communication can be an effective way of treating the body and the mind. The active inference theory suggests that chronic pain and emotional disorders can be attributed to distorted and exaggerated patterns of interoceptive and proprioceptive inference. We propose that the nature of active inference is abductive. As such, to rectify aberrant active inference processes, we should change the “Rule” of abduction, or the “prior (...) beliefs” entailed by a patient’s generative model. This means pre-existing generative models should be replaced with new models. To facilitate such replacement—or updating—the present treatment proposes that we should weaken prior beliefs, especially the one at the top level of hierarchical generative models, thereby altering the sense of agency, and redeploying attention. Then, a new prior belief can be installed through inner communication along with manual touch. The present paper proposes several hypotheses for possible experimental studies. If touch with verbal guidance is proven to be effective, this would demonstrate the relevance of active inference and the implicit prediction model at a behavioral level. Furthermore, it would open new possibilities of employing inner communication interventions, including self-talk training, for a wide range of psychological and physical therapies. (shrink)

In 1943, a distinguished child psychiatrist at Johns Hopkins University, Leo Kanner, published what would become a landmark article: a description of 11 children who suffered from a distinct disorder he called ‘infantile autism’. While initially quite obscure, in the early 1950s Kanner’s report garnered much attention, as clinicians and researchers interpreted these case studies as exemplifying the ill-effects of maternal deprivation, a new theory that rapidly gained currency in the United States. Sensory deprivation experiments, performed in the mid-1950s, further (...) complicated the picture, as experts debated whether maternal deprivation was unique or simply a form of environmental stimulation. As experts strove to make sense of this new disorder, they relied on concepts of maternal and sensory deprivation, both to promote their own theories and to critique or refute those of their colleagues. This interplay between the two theories also informed new forms of intervention, including ‘rage reduction therapy’, which served as a precursor for controversial forms of therapy today termed as the ‘attachment therapies’. This article sheds light on a little-known aspect of the history of autism, and examines the far-reaching effect popular etiological theories have in shaping debates over emerging medical concerns.

We experience our own body through both touch and vision. We further see that others’ bodies are similar to our own body, but we have no direct experience of touch on others’ bodies. Therefore, relations between vision and touch are important for the sense of self and for mental representation of one’s own body. For example, seeing the hand improves tactile acuity on the hand, compared to seeing a non-hand object. While several studies have demonstrated this (...) visual enhancement of touch effect, its relation to the ‘bodily self’, or mental representation of one’s own body remains unclear. We examined whether VET is an effect of seeing a hand, or of seeing my hand, using the rubber hand illusion. In this illusion, a prosthetic hand which is brushed synchronously—but not asynchronously—with one’s own hand is felt to actually be one’s hand. Thus, we manipulated whether or not participants felt like they were looking directly at their hand, while holding the actual stimulus they viewed constant. Tactile acuity was measured by having participants judge the orientation of square-wave gratings. Two characteristic effects of VET were observed: cross-modal enhancement from seeing the hand was inversely related to overall tactile acuity, and participants near sensory threshold showed significant improvement following synchronous stroking, compared to asynchronous stroking or no stroking at all. These results demonstrate a clear functional relation between the bodily self and basic tactile perception. (shrink)

Aristotle is history’s most famous and influential proponent of the view that there are exactly five senses. But was he entitled to hold this view, given his other commitments? In particular, was he entitled to treat touch as a single sense, given the diversity of its correlated objects? In this paper I argue that Aristotle wished to individuate touch on the basis of its correlated objects, just as he had the other four senses. I also argue, contrary (...) to what is often supposed, that he was well-placed to do so, given his other commitments and views. (shrink)

In the opening essay of The Muses, Nancy asks what force disperses Art into a plurality of arts, and what simultaneously holds them together in the unity of Art, through this very dispersal. The idea of Art, as a plurality of irreducible singularities that nevertheless commune, developed in the essay, is a precursor to the ontology of Being Singular Plural, widely considered one of his most important works. The claim in The Muses is not only that art itself has to (...) be understood as a unity of a plurality of singularities, but that it is a privileged site for the revealing of the singular plural of being. The following essay explores Nancy’s ontology of art, which is simultaneously a way of understanding being in terms of art, by tracing it back to Merleau-Ponty. I argue that Merleau-Ponty’s understanding of the sense of being in terms of the “chiasm” (the touching-touched) in The Visible and the Invisible is a crucial source for Nancy’s pluralist ontology. The turn to Merleau-Ponty is framed as a way of emphasizing that Nancy remains committed to a philosophical or ontological idea of art (despite his own criticisms of the very idea) against those who would like to separate his pluralist idea of art from any reference to the question of the meaning of “being.” The argument is that radical pluralism requires, paradoxically, an ontology, just as the affirmation of the irreducible plurality of singular arts requires a notion of Art. Dans l’essai qui ouvre Les muses, Nancy se demande quelle force disperse l’Art dans les arts et retient simultanément leur dispersion dans l’unité de l’Art. L’idée d’Art en tant qu’une pluralité irréductible de singularités qui communient malgré ou grâce à cette pluralité, telle qu’elle est développée dans cet essai, constitue un précurseur de l’ontologie présentée dans Être singulier pluriel, un des ouvrages les plus importants de Nancy. Cet article explore l’ontologie de l’art nancéenne, qui est aussi à la fois une façon de comprendre l’être en tant qu’art, en en retraçant les racines chez Merleau-Ponty. Je soutiens que la compréhension du sens de l’être comme chiasme (touchant-touché) chez le Merleau-Ponty du Visible et l’invisible est une source décisive de l’ontologie pluraliste de Nancy. Le recours à Merleau-Ponty permet de souligner le fait que Nancy demeure attaché à une idée philosophique ou ontologique de l’art, malgré ses propres critiques de l’idée même. Cette interprétation va à l’encontre de celles qui chercheraient à détacher le concept pluraliste d’art chez Nancy de toute référence à la question du sens de l’« être ». Ma contention est que le pluralisme radical requiert, paradoxalement, une ontologie, de la même façon que l’affirmation de l’irréductible pluralité des arts singuliers requiert une notion d’Art.Nel saggio che apre Le muse, Nancy si domanda quale forza disperda l’Arte in una pluralità di arti, e cosa al contempo mantenga queste ultime legate nell’unità dell’Arte a dispetto di questa dispersione stessa. L’idea di Arte, sviluppata in questo saggio, come pluralità di singolarità irriducibili che nonostante tutto si trovano a contatto e in comunicazione, prelude all’ontologia di Essere singolare plurale, tra le opere più importanti di Nancy. Ne Le muse Nancy sostiene non soltanto che l’arte in sé debba essere concepita come l’unità di una pluralità di singolarità, ma anche che essa sia un luogo privilegiato per il rivelarsi del singolare plurale dell’essere. Questo articolo esplora l’ontologia dell’arte di Nancy, che è al contempo un modo di comprendere l’essere nei termini dell’arte, attraverso un richiamo a Merleau-Ponty. Mi propongo così di mostrare che la concezione del senso dell’essere di Merleau-Ponty nei termini del “chiasmo” (il “toccante-toccato”), espressa ne Il visibile e l’invisibile, sia una fonte cruciale per l’ontologia pluralista di Nancy. Il richiamo a Merleau-Ponty è volto a sottolineare come Nancy rimanga fedele a un’idea filosofica o ontologica di arte (nonostante le sue stesse critiche a questa idea), in opposizione a coloro che vorrebbero separare la sua idea pluralista di arte da qualunque riferimento alla questione del significato dell’“essere”. La mia tesi è che il pluralismo radicale richieda, paradossalmente, un’ontologia, esattamente come l’affermazione della pluralità irriducibile delle arti singolari richiede la nozione di Arte.

This chapter deals with Immanuel Kant's remarks on touch and vision in the context of his pragmatic anthropology, by considering his views of the scope, aims, and methods of that fledgling discipline. Kant supports his discussion with appeals to observation and experience that form a kind of everyday phenomenology of sensory experience. The chapter considers Kant's notion of the relation between the pragmatic and the theoretical, including his remarks that a pragmatic anthropology does not present theoretical or scholastic knowledge (...) but focuses on worldly knowledge. Kant derived the framework for his discussion of the five external senses from his lectures on metaphysics, especially those on empirical psychology. In both empirical psychology and anthropology he categorizes the senses into those that are comparatively objective and those that are comparatively subjective: the objective senses provide more cognition, and provide occasion for reflection, but the subjective senses have more sensation than reflection.

This paper explores the significance of Heraclitus’s fragment B45 for Husserl and Merleau-Ponty as it appears in the Crisis of the European Sciences and Merleau-Ponty’s lectures on this text in the late 1950s. I claim that at stake is a revision or mutation of the sense of transcendentality: by naming it psyche, the transcendental is no longer understood as a static set of a priori conditions but what I call, following Jean-Luc Nancy, “outsidedness.” I elaborate this idea in dialogue (...) with Nancy and Derrida in their texts “De l’âme” and On Touching: Jean-Luc Nancy. By identifying the sense of transcendentality with the psyche of Heraclitus, we see a transcendentality in the process of departing, and hence transcendentality is an event for which we always arrive late.Cet article explore la signification du fragment B45 de Héraclite pour Husserl et Merleau-Ponty telle qu’elle apparaît dans la Crise des Sciences Européennes et dans la lecture de ce texte par Merleau-Ponty à la fin des années 1950. Je postule qu’il en va de la révision ou de la mutation du sens de la « transcendantalité » : en l’appelant psyche, le transcendantal n’est plus compris comme un ensemble statique de conditions a priori mais comme ce que je nomme, suivant Jean-Luc Nancy, un « au-delà ». J’élabore cette idée en dialogue avec les textes de Nancy et de Derrida : « De l’âme » et Le Toucher, Jean-Luc Nancy. En identifiant le sens de la « transcendantalité » avec la psyche de Héraclite, nous remarquons une « transcendantalité » sur le départ, et donc la « transcendantalité » est un événement pour lequel nous arrivons toujours en retard. Questo saggio esplora il significato del frammento di Eraclito B45 per Husserl e Merleau-Ponty, per come appare nella Crisi delle scienze europee e nella lettura merleau-pontiana di questo testo verso la fine degli anni Cinquanta. Ci sembra di poter affermare che in gioco vi sia una rivisitazione, una mutazione, del senso del trascendentale: definendolo come psyche, il trascendentale non è più concepito come una serie statica di condizioni a priori, ma come ciò che, con Jean-Luc Nancy, chiamiamo “esteriorità”. Abbiamo elaborato questa idea in dialogo con Nancy e Derrida e i loro testi rispettivi Dell’anima e Toccare, Jean-Luc Nancy. Identificando il senso della trascendentalità con la psyche di Eraclito, possiamo vedere della trascendentalità nel processo del dipartirsi (partance), e quindi, proprio in questo senso, comprendere la trascendentalità come un evento rispetto al quale siamo sempre in ritardo.

In NE III.10, 1118b1–3, Aristotle says that the “most shared of the senses is that according to which intemperance [comes about], and it would seem justifiably to be shameful, because it inheres [in us] not insofar as we are human beings, but insofar as we are animals”. This statement appears to describe the sense of touch as shameful. This may seem like a strange position for Aristotle to hold, since elsewhere he describes human touch as the most (...) accurate among animal species, which corresponds to our superior intelligence, and as necessary for animal life. In this paper, I argue that Maimonides nevertheless succeeds in showing that Aristotle has a strong theoretical reason for maintaining that the sense of touch is shameful. Maimonides shows that, based on principles of Aristotelian psychology, human touch is indeed shameful because it obstructs intellectual activity. (shrink)

A Sense of Beauty -- Hearing -- Seeing -- Touching -- Tasting -- Smelling -- Epilogue.

If I see, hear, or touch a sparrow, the sparrow seems real to me. Unlike Bigfoot or Santa Claus, it seems to exist; I will therefore judge that it does indeed exist. The “sense of existence” refers to the kind of awareness that typically grounds such ordinary judgments of existence or “reality.” The sense of existence has been invoked by Humeans, Kantians, Ideologists, and the phenomenological tradition to make substantial philosophical claims. However, it is extremely controversial; its (...) very existence has been called into question. This paper aims to clarify the nature and reality of the sense of existence by studying a psychiatric condition in which the sense appears to be disrupted: depersonalization disorder (DPD). (shrink)

It is through touch that we are able to interact directly with the world; it is our primary conduit of both pleasure and pain. Touch may be our most immediate and powerful sense—“the first sense" because of the central role it plays in experience. In this book, Matthew Fulkerson proposes that human touch, despite its functional diversity, is a single, unified sensory modality. Fulkerson offers a philosophical account of touch, reflecting the interests, methods, and (...) approach that define contemporary philosophy; but his argument is informed throughout by the insights and constraints of empirical work on touch. Human touch is a multidimensional object of investigation, Fulkerson writes, best served by using a variety of methods and approaches. -/- To defend his view of the unity of touch, Fulkerson describes and argues for a novel, unifying role for exploratory action in touch. He goes on to fill in the details of this unified, exploratory form of perception, offering philosophical accounts of tool use and distal touch, the representational structure of tangible properties, the spatial content of touch, and the role of pleasure in tactual experience. -/- Fulkerson’s argument for the unique role played by exploratory action departs notably from traditional vision-centric philosophical approaches to perception, challenging the received view that action plays the same role in all sensory modalities. The robust philosophical account of touch he offers in The First Sense has significant implications for our general understanding of perception and perceptual experience. (shrink)

The rubber hand illusion (RHI) is the experience of an artificial body part as being a real body part and the experience of touch coming from that artificial body part. An explanation of this illusion would take significant steps towards explaining the experience of embodiment in one’s own body. I present a new cognitive model to explain the RHI. I argue that the sense of embodiment arises when an on-line representation of the candidate body part is represented as (...) matching an off-line prototype representation of what one’s body is usually like. The cause of the sense of embodiment in the model body part only partially overlaps with the causes of proprioceptive drift, which commonly accompanies the RHI, and so is compatible with observed dissociations between the illusion and proprioceptive drift. The distinguishing features of this model are the off-line body representation, and the process of matching an on-line model to an off-line model, both of which are to be understood in terms of a conceptual space. -/- Key Words: Rubber Hand Illusion; RHI; Sense of Embodiment; Self Consciousness; Body Experience.

The rubber hand illusion is one of the most commonly used paradigms to examine the sense of body ownership. Touches are synchronously applied to the real hand, hidden from view, and a false hand in an anatomically congruent position. During the illusion one may perceive that the feeling of touch arises from the false hand, and that the false hand is one's own. The relationship between referral of touch and body ownership in the illusion is unclear, and (...) some articles average responses to statements addressing these experiences, which may be inappropriate depending on the research question of interest. To address these concerns, we re-analyzed three freely available datasets to better understand the relationship between referral of touch and feeling of ownership in the RHI. We found that most participants who report a feeling of ownership also report referral of touch, and that referral of touch and ownership show a moderately strong positive relationship that was highly replicable. In addition, referral of touch tends to be reported more strongly and more frequently than the feeling of ownership over the hand. The former observations confirm that referral of touch and ownership are related experiences in the RHI. The latter, however, indicate that when pooling the statements one may obtain a higher number of illusion ‘responders’ compared to considering the ownership statements in isolation. These results have implications for the RHI as an experimental paradigm. (shrink)

This paper explores how touch is key to understanding education—not as an achievement or an instrument of acquisition, but as a process through which one becomes a subject capable of both living and leading a life that matters for ourselves and others. As a process, it is concerned with how we encounter things and others in the world and not solely with what we encounter. In particular, it argues that the dynamics of touch-as both a touching and being (...) touched by-are central for understanding educational encounters as sensory landscapes of contact. This paper turns first to Aristotle’s understanding of touch as central to life itself in order to contemplate how it is not merely one of the senses but signifies as the primary mode of all bodily contact with the world. This vital aspect will then be examined in relation to the specific ways bodies experience contact, through their membranes, morphological make up and their movements. Here, I draw on a number of philosophers and theorists, such as Maxine Sheets-Johnstone, Juhani Pallasmaa and Erin Manning, and a recent art installation The Boarding School by Sisters Hope to demonstrate how bodies matter to the very practices of education. I conclude with some thoughts on what morphologies, membranes and movements can specifically offer to a sensuous understanding of education. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Aspiration to the Condition of TouchChristopher Perricone"The Dance," written by William Carlos Williams in 1944 is one of my favorite poems: I return to it regularly. Williams gives us a feel for that life of the kermess (a carnival) in his poem through Breughel's picture, as it were three times removed from the event itself. Of course, unlike Plato, I would argue that the vitality of the kermess (...) is not lost in the poem; it is actually enhanced by a subtle sleight of hand. The poem isn't primarily about Breughel's picture. It is about dance, about the dancers who go round, their squeal, the crude music, its rollicking measures, the dancers kicking and rolling and swinging, their hips, bellies, and butts. Reading and re-reading this poem, I "see" those ordinary folk of Breughel's great picture. I "hear" their music. I "move" to their dance. The poem seems a condensation, a summary of the fine arts. Perhaps the poem is about poetry's power to reinvigorate imaginatively what we hear and see. Perhaps I think of festivities at which I have danced, how such festivities are essential to the human experience. Perhaps, William Carlos Williams in 1944, World War II coming to a close, was anticipating similar good times. As always, it's best to let the poem speak for itself:In Breughel's great picture, The Kermess,the dancers go round, they go round and around, the squeal and the blare and the tweedle of bagpipes, a bugle and fiddles tipping their bellies (round as the thick-sided glasses whose wash they impound) their hips and their bellies off balance to turn them. Kicking and rolling about the [End Page 229] Fair Grounds, swinging their butts, those shanks must be sound to bear up under such rollicking measures, prance as they dance In Breughel's great picture, The Kermess.The visual, musical, and literary arts do much to educate our senses, especially our senses of sight and hearing. The well-formed visual and auditory sensations we gain from the arts are, as it were, the melody of those experiences. They are the images we store away, the tunes we whistle. However, here, I want to draw attention to an overlooked, although not entirely disregarded, sense, i.e., touch. I want to argue that touch is the bass line to the melody of sight and hearing in the arts, i.e., that touch keeps the work of art coherent and grounded.This is an old idea. Bernhard Berenson had the idea when he was examining the painters of the Italian renaissance. Berenson argued that great painting stimulates touch, which inspires, our "tactile imagination," which produces our "tactile values." Here lay, according to Berenson the genius of Giotto. Tactile imagination and values enchance the "material significance" of a work; they act as a "test of reality." Berenson was on to something not only about painting but about the arts in general. However, in the late nineteenth and early twentieth centuries he lacked the scientific evidence about touch and its role in human relationships to develop his idea of tactile values to any great extent.1Although Berenson had keen intuitions, he didn't know about the biological/psychological nuts and bolts of touch. Thus, he never knew about the detailed nature and extent of our physical contact with other physical things in the world. He didn't know about Merkel's discs, Ruffini and Pacinian corpuscles. He didn't know about hierarchical and parallel levels of brain processing. Berenson didn't know that more brain space in the somatosensory cortex is given to the hand than to any other part of the body, that your fingers especially have a high density of touch receptors compared to other body areas. Today, all this information is standard textbook fare.2 Many neuroscientific details need to be worked. However, a general picture based on hard evidence has begun to emerge.This information adds significant substance to Berenson's ideas. Berenson's "third dimension" is essentially a sense of temperature, pressure, vibration, and texture. And chances are the tactile imagination is inspired most by what is touched by... (shrink)

In 1925, David Katz published an influential monograph on touch, Der Aufbau der Tastwelt, which was translated into English in 1989. Although it is called “the world of touch,” it also discusses the thermal and the nociceptive senses, albeit briefly. In this chapter, we will follow this approach, but we will speak about “somatosensory senses” in general in order to remind ourselves that perceptions of temperatures and pains should also be considered together in this context.

The sense of touch informs us of the physical properties of our surroundings and is a critical aspect of communication. Before touches are perceived, mechanical signals are transmitted quickly and reliably from the skin's surface to mechano‐electrical transduction channels embedded within specialized sensory neurons. We are just beginning to understand how soft tissues participate in force transmission and how they are deformed. Here, we review empirical and theoretical studies of single molecules and molecular ensembles thought to be involved (...) in mechanotransmission and apply the concepts emerging from this work to the sense of touch. We focus on the nematode Caenorhabditis elegans as a well‐studied model for touch sensation in which mechanics can be studied on the molecular, cellular, and systems level. Finally, we conclude that force transmission is an emergent property of macromolecular cellular structures that mutually stabilize one another. (shrink)

Assumption: Sensory modalities are individuated by their proper objects. Hearing is the direct perception of sounds, sight the direct perception of colours, etc. Objection: There is no single type of proper sensibles in the case of touch (temperature, solidity, hardness, humidity, texture, weight, vibration...). Answer : 1. accept to distinguish the sense of pressure (touch strictly speaking) from the sense of temperature. 2. argue that pressures are the direct perceptual objects through which one perceives weight, texture, (...) solidity.

For the first time, David Katz's classic monograph _The World of Touch_ has been translated into English. Regarded as one of the premiere experimental psychologists, Katz vigorously opposed the atomism and "tachistoscopic" mentality typical of the sensory psychology of his day. In _The World of Touch_, Katz sought to dispel the invidious distinction between the supposedly higher and lower senses. To help touch regain its original prominence in the field, Katz demonstrated, through very simple, yet creative experiments, how fascinating (...) the abilities of touch are, and how valuable the tactual stimulus can be in specifying objects, surfaces, substances, and events. In addition, Katz emphasized the importance of higher-order invariants in the perception of objects, and the holistic quality of perception in time as well as space. (shrink)
