Neuropsychological findings used to motivate the "two visual systems" hypothesis have been taken to endanger a pair of widely accepted claims about spatial representation in conscious visual experience. The first is the claim that visual experience represents 3-D space around the perceiver using an egocentric frame of reference. The second is the claim that there is a constitutive link between the spatial contents of visual experience and the perceiver's bodily actions. In this paper, I review and assess three main (...) sources of evidence for the two visual systems hypothesis. I argue that the best interpretation of the evidence is in fact consistent with both claims. I conclude with some brief remarks on the relation between visual consciousness and rational agency.

Modeling social interactions based on individual behavior has always been an area of interest, but prior literature generally presumes rational behavior. Thus, such models may miss out on capturing the effects of biases humans are susceptible to. This work presents a method to model egocentric bias, the real-life tendency to emphasize one's own opinion heavily when presented with multiple opinions. We use a symmetric distribution, centered at an agent's own opinion, as opposed to the Bounded Confidence (BC) model used (...) in prior work. We consider a game of iterated interactions where an agent cooperates based on its opinion about an opponent. Our model also includes the concept of domain-based self-doubt, which varies as the interaction succeeds or not. An increase in doubt makes an agent reduce its egocentricity in subsequent interactions, thus enabling the agent to learn reactively. The agent system is modeled with factions not having a single leader, to overcome some of the issues associated with leader-follower factions. We find that agents belonging to factions perform better than individual agents. We observe that an intermediate level of egocentricity helps the agent perform at its best, which concurs with conventional wisdom that neither overconfidence nor low self-esteem brings benefits.

The paper briefly summarises and critiques Tomasello’s A Natural History of Human Thinking. After offering an overview of the book, the paper focusses on one particular part of Tomasello’s proposal on the evolution of uniquely human thinking and raises two points of criticism against it. One of them concerns his notion of thinking. The other pertains to empirical findings on egocentric biases in communication.

This chapter offers an indirect defence of the Evansian conception of egocentric space, by showing how it resolves a puzzle concerning the unity of egocentric spatial perception. The chapter outlines several common assumptions about egocentric perspectival structure and argues that a subject’s experience, both within and across her sensory modalities, may involve multiple structures of this kind. This raises the question of how perspectival unity is achieved, such that these perspectival structures form a complex whole, rather than (...) merely disunified set of individually, distinctively structured experiences. The shortcomings of variety of accounts are considered: switch accounts ; sensory accounts; transformation accounts; and ultimate accounts. These shortcomings are addressed by a further kind of account provided by the Evansian conception – an agentive account – according to which egocentrically structured experiences present the world in relation to parts of a single thing, the body as a dynamic unity.

This paper defends the view that one's own mental states are metaphysically privileged vis-à-vis the mental states of others, even if only subjectively so. This is an instance of a more general view called Subjectivism, according to which reality is only subjectively the way it is. After characterizing Subjectivism in analogy to two relatively familiar views in the metaphysics of modality and time, I compare the Subjectivist View of the Mental with Egocentric Presentism, a version of Subjectivism recently advocated (...) by Caspar Hare. I argue that the Subjectivist View of the Mental goes a considerable way towards solving certain long-standing philosophical puzzles having to do with the unity of consciousness, the contents of self-awareness and the intransmissibility of experiential knowledge through testimony.

I am aware of the red and orange autumn leaves. Am I aware of my awareness of the leaves? Not so according to many philosophers. By contrast, many meditative traditions report an experience of awareness itself. I argue that such a pure awareness experience must have a non-sensory phenomenal character. I use Douglas Harding’s first-person experiments for assisting in recognizing pure awareness. In particular, I investigate the gap where one cannot see one’s head. This is not a mere gap because (...) I seem to be looking from here. Critically, I claim, the experience of looking from here has a non-sensory phenomenal character. I argue that this sense of being aware cannot be reduced to egocentric visual spatial relations nor the viewpoint because it continues when I close my eyes. Neither is a multisensory origin sufficient to explain why I seem to be at this central point rather than elsewhere. Traditionally, claims of a pure awareness experience have been restricted to highly trained individuals in very restricted circumstances. The innovation of Harding’s approach is that it reliably isolates a candidate for pure awareness using methods which can be replicated at any time. (shrink)

According to the decomposition thesis, a subject’s total perceptual experience at a time is an aggregate of discrete, modality‐specific experiences. Contrary to this view, I argue that certain cases of multisensory integration give rise to experiences that represent features of a novel type. Through the coordinated use of bodily awareness – understood here as encompassing both proprioception and kinaesthesis – and the exteroceptive sensory modalities, one becomes perceptually responsive to spatial features whose instances couldn’t be represented by any of the (...) contributing modalities functioning in isolation. I develop an argument for this conclusion focusing on two cases: 3D shape perception in haptic touch and experiencing an object’s egocentric location in crossmodally accessible space. (shrink)

According to “actionism” (Noë 2010), perception constitutively depends on implicit knowledge of the way sensory stimulations vary as a consequence of the perceiver’s self-movement. My aim in this contribution is to develop an alternative conception of the role of action in perception present in the work of Gareth Evans using resources provided by Ruth Millikan’s biosemantic theory of mental representation.

The problem of amodal perception is the problem of how we represent features of perceived objects that are occluded or otherwise hidden from us. Bence Nanay (2010) has recently proposed that we amodally perceive an object's occluded features by imaginatively projecting them into the relevant regions of visual egocentric space. In this paper, I argue that amodal perception is not a single, unitary capacity. Drawing appropriate distinctions reveals amodal perception to be characterized not only by mental imagery, as Nanay (...) suggests, but also by genuinely visual representations as well as beliefs. I conclude with some brief remarks on the role of object-directed bodily action in conferring a sense of unseen presence on an object's occluded features. (shrink)

Milner and Goodale's influential account of the primate cortical visual streams involves a division of consciousness between them, for it is the ventral stream that has the responsibility for visual consciousness. Hence, the dorsal visual stream is a ‘zombie’ stream. In this article, I argue that certain information carried by the dorsal stream likely plays a central role in the egocentric spatial content of experience, especially the experience of visual spatial constancy. Thus, the dorsal stream contributes to a pervasive (...) feature of consciousness. (shrink)

It is not uncommon for philosophers to name disinterestedness, or some like feature, as an essential characteristic of love. Such theorists claim that in genuine love, one’s concern for her beloved must be non-instrumental, non-egocentric, or even selfless. These views prompt the question, “What, if any, positive role might self-interestedness play in genuine love?” In this paper, I argue that attachment, an attitude marked primarily by self-focused emotions and emotional predispositions, helps constitute the meaning and import of at least (...) some kinds of adult reciprocal love. In this way, attachment represents a type of self-interestedness that not only contributes positively to such relationships but is also essential to them. (shrink)

Jennifer Nagel (2010) has recently proposed a fascinating account of the decreased tendency to attribute knowledge in conversational contexts in which unrealized possibilities of error have been mentioned. Her account appeals to epistemic egocentrism, or what is sometimes called the curse of knowledge, an egocentric bias to attribute our own mental states to other people (and sometimes our own future and past selves). Our aim in this paper is to investigate the empirical merits of Nagel’s hypothesis about the psychology (...) involved in knowledge attribution. (shrink)

The purpose of this paper is to defend what I call the action-oriented coding theory (ACT) of spatially contentful visual experience. Integral to ACT is the view that conscious visual experience and visually guided action make use of a common subject-relative or 'egocentric' frame of reference. Proponents of the influential two visual systems hypothesis (TVSH), however, have maintained on empirical grounds that this view is false (Milner & Goodale, 1995/2006; Clark, 1999; 2001; Campbell, 2002; Jacob & Jeannerod, 2003; Goodale (...) & Milner, 2004). One main source of evidence for TVSH comes from behavioral studies of the comparative effects of size-contrast illusions on visual awareness and visuo- motor action. This paper shows that not only is the evidence from illusion studies inconclusive, there is a better, ACT-friendly interpretation of the evidence that avoids serious theoretical difficulties faced by TVSH.

When I act on something, three kinds of idea (or representation) come into play. First, I have a non-visual representation of my goals. Second, I have a visual description of the kind of thing that I must act upon in order to satisfy my goals. Finally, I have an egocentric position locator that enables my body to interact with the object. It is argued here that these ideas are distinct. It is also argued that the egocentric position locator (...) functions in the same way as a demonstrative, and that the involvement of such demonstratives in visual content negates naive realism.

It is a shorter revised version of "Visual Reference", posted earlier.). (shrink)

It has been claimed that photographs are transparent: we see through them; we literally see the photographed object through the photograph. Whether this claim is true depends on the way we conceive of seeing. There has been a controversy about whether localizing the perceived object in one's egocentric space is a necessary feature of seeing, as if it is, then photographs are unlikely to be transparent. I would like to propose and defend another, much weaker, necessary condition for seeing: (...) I argue that it is necessary for seeing that there is at least one way for me to move such that if I were to move this way, my view of the perceived object would change continuously as I move. Since this condition is not satisfied in the case of seeing objects in photographs, photographs are not transparent. (shrink)

Our perception of where touch occurs on our skin shapes our interactions with the world. Most accounts of cutaneous localisation emphasise spatial transformations from a skin-based reference frame into body-centred and external egocentric coordinates. We investigated another possible method of tactile localisation based on an intrinsic perception of ‘skin space’. The arrangement of cutaneous receptive fields (RFs) could allow one to track a stimulus as it moves across the skin, similarly to the way animals navigate using path integration. We (...) applied curved tactile motions to the hands of human volunteers. Participants identified the location midway between the start and end points of each motion path. Their bisection judgements were systematically biased towards the integrated motion path, consistent with the characteristic inward error that occurs in navigation by path integration. We thus showed that integration of continuous sensory inputs across several tactile RFs provides an intrinsic mechanism for spatial perception. (shrink)

I examine the ordinary-language use of deictic terms, notably the personal, spatial and temporal markers 'I' and 'you', 'here' and 'now', in order to make manifest that their meaning is inextricably embedded within a pragmatic, perceptual and interpersonal situation. This inextricable embeddedness of deixis within the shared natural and social world suggests, I contend, an I-you connectedness at the heart of meaning and experience. The thesis of I-you connectedness extends to the larger claim about the situatedness of embodied perceivers within (...) a shared perspectivally configured milieu. This claim can be cast in terms of a polycentric orientation to the natural and social world, which provides a robust alternative to an egocentric conception of experience. I develop this claim via a renewed phenomenological reflection on speech, assisted by ordinary-language philosophy, as well as relevant contributions from empirical sociolinguistic studies and developmental psychology. These reflective and empirical perspectives help make a case for the primacy of socially and spatially situated experience, which departs from the received notion of an asocial and uprooted mind.

According to proponents of the sensorimotor contingency theory of perception (Hurley & Noë 2003, Noë 2004, O’Regan 2011), active control of camera movement is necessary for the emergence of distal attribution in tactile-visual sensory substitution (TVSS) because it enables the subject to acquire knowledge of the way stimulation in the substituting modality varies as a function of self-initiated, bodily action. This chapter, by contrast, approaches distal attribution as a solution to a causal inference problem faced by the subject’s perceptual systems. (...) Given all of the available endogenous and exogenous evidence available to those systems, what is the most probable source of stimulation in the substituting modality? From this perspective, active control over the camera’s movements matters for rather different reasons. Most importantly, it generates proprioceptive and efference-copy based information about the camera’s body-relative position necessary to make use of the spatial cues present in the stimulation that the subject receives for purposes of egocentric object localization.

Menschen verfügen über ein komplexes Vermögen der Selbstlokalisierung in Raum und Zeit. Seine eigene Position festzustellen kann in verschiedenen Kontexten Verschiedenes bedeuten. Nicht jedes unsere raumzeitliche Lokalisierung und Orientierung betreffende Problem ist philosophischer Natur. Fragen wie »Wo ist Norden?«, »Wie weit ist es nach Hause?« oder »In welcher Richtung liegt das Ziel?« sind lebensweltliche und gegebenenfalls navigatorische Fragen. Die kognitiven Mechanismen und Fähigkeiten zu untersuchen, die unseren Lokalisierungs- und Orientierungsleistungen zugrunde liegen, ist eine Aufgabe für die Kognitionswissenschaften. Die Untersuchung der (...) Grundlagen unserer Orientierungsfähigkeit wirft aber auch begriffliche Fragen auf, und diese zu klären ist eine philosophische Aufgabe. Wichtige Beiträge dazu haben Kant, Husserl, Strawson, Tugendhat und Gareth Evans geleistet. Truls Wyller steht in dieser Reihe und hat wie kein anderer den transzendentalphilosophischen Gehalt von Lokalisierungs- und Orientierungsfragen herausgearbeitet. Gegen naturalistische Verkürzungen hat er mit großer Beharrlichkeit dafür argumentiert, dass das Vermögen, seine eigene Position in Raum und Zeit zu bestimmen, Implika-tionen hat, die die Bedingung der Möglichkeit von Erfahrung betreffen. Die folgende Skizze ist ungleich bescheidener angelegt. Ich werde wenig mehr tun, als wesentliche Einsichten der Literatur zur raumzeitlichen Selbstlokalisierung zusammenzutragen, wobei ich einige Akzente anders setze als Wyller. Insbesondere werde ich versuchen, so weit wie möglich ohne Transzendentalen Idealismus auskommen. Im Zentrum meiner Skizze steht das klärungsbedürftige Verhältnis zwischen indexikalischen und nicht-indexikalischen Orts- und Zeitbestimmungen sowie den zugehörigen Lokalisierungsverfahren. (shrink)

This article addresses the question whether skiing as a nature sport enables practitioners to develop a rapport with nature, or rather estranges and insulates them from their mountainous ambiance. To address this question, I analyse a recent skiing movie from a psychoanalytical perspective and from a neuro-scientific perspective. I conclude that Jean-Paul Sartre’s classical but egocentric account of his skiing experiences disavows the technicity involved in contemporary skiing as a sportive practice for the affluent masses, which actually represents an (...) urbanisation of the sublime, symptomatic for the current era.

Deafferented subjects, while lacking proprioceptive awareness of much of their bodies, are nevertheless able to use their bodies in basic action. Sustained visual contact with the body parts of which they are no longer proprioceptively aware enables them to move these parts in a controlled way. This might be taken to straightforwardly show that proprioceptive awareness is inessential to bodily action. I, however, argue that this is not the case. Proprioceptive awareness figures essentially in our self-conscious unity as practical subjects. (...) Recognizing this allows us to better understand the nature of the impairment with which deafferented subjects live. (shrink)

The activities of man and other beings on a daily basis have been the primordial antecedence for the negative changes experienced in the environment today. Nature in its rudimentary state was harmless and friendly to man and its inhabitants. But owing to the egocentric approaches of man towards the environment, fundamentally for the purpose of earning a living and advancing development, man manipulates every available resources to his favor including the environment. These egomaniacal demeanor has propelled the once harmless (...) nature to react against human beings, causing socio-economic and psychological damages. Climate change to this end has been defined as a change in oceans, land surfaces and ice sheets occurring overtime scales of decades or longer. It expresses itself in the evidence differentiation from the usual sun radiation, volcanoes, internal virility in climate system or human system. The twenty first century is facing the boomerang of the human seeds sown on the climate. It becomes imperative for Africans to align with the rest of the world in fashioning out an approach to tackle climate change and other related environmental issues, and curb the present and predicted damages. To this end the paper proposes Innocent Asouzu’s complementary Noetic Propaedeutic principle as the viable prognosis towards fostering environmental peace, mutual co-existence with all other beings within the horizon to bring about solution to climate change. The paper explores the philosophical methods of analysis and prescription in its research. (shrink)

Kendall Walton argues that photographs, like mirrors and microscopes, meet sufficient conditions to be considered a kind of prosthesis for seeing. Well aware of the controversiality of this claim, he offers three criteria for perception met by photographs like other perceptual aids which makes them transparent –that is, we see through them.1(II) Jonathan Cohen and Aaron Meskin attempt to refute the transparency thesis by arguing that photographs cannot be genuine prostheses for seeing because they fail to meet another necessary condition, (...) namely that of egocentric spatial information (ESI). Only devices that belong to a process type that carries ESI are, in principle, genuine prostheses for seeing.2 (III) I will offer a two- part refutation of the proposed disqualification of photographs by 1) offering an example of a case where another instance of the process-type to which photographs belong carries ESI, establishing the reliability of the process type that allegedly precluded photographs from qualifying (IV) and 2) offering another example to illustrate how photographs can meet the ESI condition.

The indexical sentence “I am here now” can be used any time and anywhere by anyone to say something true. Rather than yielding a special kind of infallible knowledge, this fact indicates that every speaker or thinker has a zero of an egocentric coordinate system at his disposal. Many idealist philosophers assume that this egocentric zero can be further reduced. The ability to make a de se-reference with the first person pronoun, they claim, need not involve spatiotemporal self-localization. (...) The paper challenges this idealistic view. Starting from the observation that even Descartes’ cogito argument, which expresses a tensed truth, involves a dated mental episode, it is argued that nothing can exist in time without being in space. The paper concludes that the egocentric zero of orientation with its three mutually dependent elements (I, here, now) cannot be further minimized. Thinkers of I-thoughts must have a spatiotemporal position. They must be Strawsonian persons rather than Cartesian egos. (shrink)

En The Varieties of Reference, Evans sostiene que el contenido perceptual posee una naturaleza no conceptual. Precisamente, los vínculos informacionales entre sujeto y objeto habilitan el pensamiento singular, al permitir la localización del objeto en un entorno egocéntrico. Anclados en algunos casos en estos vínculos, los pensamientos singulares contienen Ideas adecuadas del objeto, dependientes de una determinada clasificación del mismo. Nada en el contenido perceptual equivale a este recorte conceptual del objeto en el pensamiento. Sostendré entonces la necesidad de introducir (...) la idea de una representación no conceptual de cosa que recortaría, de dicho contenido, un punto de anclaje para la representación informacional. In The Varieties of Reference, Evans claims that perceptual content has a non-conceptual nature. Concretely, the informational links between subject and object allow singular thought by permitting the localization of the object in an egocentric space. Anchored in some cases in these links, singular thoughts contain adequate Ideas of the object that depend on a certain classification of it. Nothing in the perceptual content corresponds to this conceptual cut of the object in thought. I will therefore underline the need to introduce the idea of a non-conceptual representation of thing that will cut, in that content, an anchoring point for the informational representation.

Research on the capacity to understand others’ minds has tended to focus on representations of beliefs, which are widely taken to be among the most central and basic theory of mind representations. Representations of knowledge, by contrast, have received comparatively little attention and have often been understood as depending on prior representations of belief. After all, how could one represent someone as knowing something if one doesn't even represent them as believing it? Drawing on a wide range of methods across (...) cognitive science, we ask whether belief or knowledge is the more basic kind of representation. The evidence indicates that non-human primates attribute knowledge but not belief, that knowledge representations arise earlier in human development than belief representations, that the capacity to represent knowledge may remain intact in patient populations even when belief representation is disrupted, that knowledge attributions are likely automatic, and that explicit knowledge attributions are made more quickly than equivalent belief attributions. Critically, the theory of mind representations uncovered by these various methods exhibit a set of signature features clearly indicative of knowledge: they are not modality-specific, they are factive, they are not just true belief, and they allow for representations of egocentric ignorance. We argue that these signature features elucidate the primary function of knowledge representation: facilitating learning from others about the external world. This suggests a new way of understanding theory of mind—one that is focused on understanding others’ minds in relation to the actual world, rather than independent from it. (shrink)

How should we think about the role of visual spatial awareness in perception and perceptual knowledge? A common view, which finds a characteristic expression in Kant but has an intellectual heritage reaching back farther than that, is that an account of spatial awareness is fundamental to a theory of experience because spatiality is the defining characteristic of “outer sense”, of our perceptual awareness of how things are in the parts of the world that surround us. A natural counterpart to this (...) idea is to treat self-consciousness as residing in a kind of sense that is fundamentally “inner”, such as introspection or whatever else gives one privileged access to his own mental states as well as the proprioceptive and kinesthetic awareness of bodily position. This division is compatible, of course, with the idea that inner sense provides an awareness of a distinctive kind of “body space”, but it treats that as importantly different from the awareness of the worldly space around one. -/- In contrast to such a picture, this dissertation proposes an account of visual spatial awareness according to which it is no less a source of self-consciousness than of the awareness of the objects around us, and an account of self-awareness in which visual experience is essentially implicated. I begin by arguing that we should think of visual spatial awareness not as necessary for the individuation of visual sensations but rather as an essential element in the awareness of an experientially objective world. In the subsequent chapters, I argue that in being visually aware of the egocentric positions of the worldly objects around us we are often aware also of our own spatial locations with respect to them, and that the visual experience of the world around one and one’s own situation in it is often an essential component in the knowledge that a human agent will have of his own intentional actions.

Structural idealism uses formal and computational techniques to describe an idealist ontology composed of God and a set of finite minds. A finite mind is a system of private intentional worlds. An intentional world is a connectionist hierarchy of intentional objects (propositions, concepts, sensible things, sensations). Intentional objects, similar to Leibnizian monads, are computing machines. To escape the egocentric predicament, Leibnizian relations of (in)compossibility exist between finite minds, linking them together into a constraint-satisfaction network, thereby coordinating their private intentional (...) worlds.
