Several claims made by Wilkins & Wakefield require qualification. First, the proposed delineation of the parietal-occipital-temporal junction (POT) is overly restrictive. Second, focusing exclusively on the evolutionary importance of manual manipulation oversimplifies interacting evolutionary preconditions for language. Finally, Wilkins and Wakefield's perspective adheres to a homocentric, formal, linguistic definition of language instead of viewing language as a multimodal sensory enhancement system unique to each species.

“What we have learned from Saussure” affirms Merleau-Ponty “is that, taken singly, signs do not signify anything, and that each one of them does not so much express a meaning as mark a divergence of meaning between itself and other signs.” While it has often been stressed that Merleau-Ponty was arguably among the earliest philosophical readers of Saussure, the real impact of this reading on Merleau-Ponty’s thinking has rarely been assessed in detail. By focusing on the middle period – the (...) years between the publication of the Phenomenology of Perception and the abandonment of the book project The Prose of the World – a special interest in language and its ideality becomes all the more evident. Now this period is crucial for understanding the turn of the later years: similarly to Saussure, who shifted the problem of meaning from a problem of referentiality to an issue of self-differentiation of the linguistic field, Merleau-Ponty shifts his account of perception from a relationship based on sensory subjects and perceived objects to an immanent differentiation of the sensible world. The genesis ofan articulated world can be conceptualized with the experience of children’s language acquisition and the phenomenon of “deflation.” At a certain point in her development, the child interrupts her incessant babbling and learns to shape pauses and silences, which are the precondition for meaningful sounds. Learning how to speak – as it were – would thus be learning how not to speak. The child may only enter a specific language by means of a phonematic restriction; to become a member of a language community is to lose the capacity to speak all languages. (shrink)

If successful scientific inquiry is to be possible, there must be a world that is independent of how we believe it to be, and in which there are kinds and laws; and we must have the sensory apparatus to perceive particular things and events, and the capacity to represent them, to form generalized explanatory conjectures, and check how these conjectures stand up to further experience. Whether these preconditions are met is not a question the sciences can answer; it is (...) specifically philosophical. This is why the myriad forms of scientistic philosophy in vogue today (neurophilosophy, experimental philosophy, naturalized metaphysics, evangelical-atheist reductionism, etc), are all hollow at the core. Does this mean we must return to the old, a priori analytic model? No! What is needed instead is scientific philosophy in the sense Peirce articulated more than a century ago: philosophy motivated by a genuine desire to discover the truth, and relying not solely on reason but also on experience—only not the special, recherché experience required by the sciences, but close attention to aspects of everyday experience so familiar we hardly notice them.

What skills are required for working with computer-controlled machines in the manufacturing area? Taking the developments in the machine building sector in Germany as an example, it becomes apparent that a human-centred approach (skill-based manufacturing) offers the companies many advantages over Tayloristic forms of work organisation and automation. Closer observations reveal that skills and qualifications based on empirical knowledge and individual capabilities, such as a feeling for machines and materials, continue to play an important part in the work with computer-controlled (...) machines. So far, however, skills of this kind have received neither practical nor systematic consideration and are regarded as tacit skills in most cases. Therefore it is particularly the use of computer technology which is likely — in most cases unintentionally — to restrict and undermine the essential preconditions necessary for the development and application of such skills.

This article examines the imagination by way of various studies in cognitive science. It opens by examining the neural correlates of bodily metaphors. It assumes a basic knowledge of metaphor studies, or the primary finding that has emerged from this field: that large swathes of human conceptualization are structured by bodily relations. I examine the neural correlates of metaphor, concentrating on the relation between the sensory motor cortices and linguistic conceptualization. This discussion, however, leaves many questions unanswered. If it (...) is the case that the sensory motor cortices are appropriated in language acquisition, how does this process occur at the neural level? What neural preconditions exist such that this appropriation is possible? It is with these questions in mind that I will turn my attention to studies of neural plasticity, degeneracy and the mirror neuron activation. Whereas some scholarship in philosophy and cognitive neuroscience has aimed to identify the neurological correlates of consciousness, examining plasticity, degeneracy and activation shifts the discussion away from a study of correlates toward an exploration of the neurological dynamics of thought. This shift seems appropriate if we are to examine the processes of the “imagination.”. (shrink)

Scheler subjects Husserl’s categorial intuition to a critique, which calls into question the very methodological procedure of phenomenology. Scheler’s divergence from Husserl with respect to whether sensory or categorial contents furnish the foundation of the act of intuition leads into a more significant divergence with respect to whether phenomenology should, primarily, be considered a form of science to which a specific methodology applies. Philosophical methods, according to Scheler, must presuppose, and not distract from, important preconditions of knowledge that pertain (...) more to the philosopher than to logical procedure. Accordingly, the phenomenological attitude serves as a foundation for, and is not the result of, the phenomenological method. (shrink)

Sometimes seeing sandal from non-smellable distance we obtain cognition in the form ‘surabhi candanam’ (that sandal out there is fragrant). According to the Naiyāyikas, this cognition is a single qualified visual perception, where fragrance is grasped by visual sense-faculty. Normally visual sense cannot grasp fragrance. But here fragrance is grasped by visual sense through an extraordinary sense-connection. The Nyāya holds that the memory of fragrance, working as cognition-induced extraordinary sensory connection (jñānalakṣaṇa alaukika sannikarṣa), connects its object, fragrance, with visual (...) sense. The Naiyāyikas use this thesis of jñānalakṣaṇa to explain illusion. For a direct realist like the Naiyāyikas, it is always difficult to explain illusion. But jñānalakṣaṇa explains how an object, which is absent in front, can be accessed directly by the operating sense-organ through an extraordinary sensory connection. However, there is a possible threat to the thesis of jñānalakṣaṇa. In the mechanism of jñānalakṣaṇa, memory plays a vital role. If one is already acquainted with the fragrance of sandal in some previous occasion, then the memory of fragrance can work as an extraordinary sensory connection for her. But the question arises as to what happens when she acquires the knowledge of fragrant sandal for the first time? Is it also an instance of extraordinary jñānalakṣaṇa perception? It is obvious that in such case no memory is there to help her connect her visual sense to fragrance. However, this first acquaintance is a precondition for the possibility of the later acquaintances of fragrant sandal. Hence, it is necessary for the Naiyāyikas to explain the mechanism of the first acquaintance of fragrant sandal. The Naiyāyikas will be able to save their thesis of jñānalakṣaṇa (and also their direct realism) if they can depict a moment-wise account of the whole process of the first acquaintance of fragrant sandal remaining consistent with their own basic tenets. It would require moment-analysis (kṣaṇavicāra) of that cognitive situation. In Nyāya-Vaiśeṣika tradition, several attempts have been made to solve the problem. Jayanta Bhaṭṭa in Nyāyamañjarī mentions that ‘madhura śarkarā’ or ‘sugandhi ketakī’ are cases of mental perception or mānasa pratyakṣa. He says that here manas functions as the means of perception being aided by external senses to produce such cognition. Jayanta Bhaṭṭa explains the other cases like illusion and recognition by the same model. On the other hand, Śrīdhara Bhaṭṭa in Nyāyakandalī says that in the case of the first acquaintance, at first the fragrance is grasped by the olfactory sense. Then, the visual sense-faculty, taking the perception of the fragrance as an associate cause, produces a cognition of the qualificand. The paper constructs several versions of moment examinations (kṣaṇavicāra) for both of these suggestions and evaluates them. It is observed that although Jayanta’s thesis may be accepted as an alternative Nyāya account of the first acquaintance of fragrant sandalwood, Śrīdhara’s account fails partially. On the other hand, Jayanta fails to explicate the inner psychological steps involved in the said cognition. This paper suggests that we can successfully construct moment examination of the first acquaintance of fragrant sandal; hence, the Nyāya thesis of jñānalakṣaṇa suffers no threat of internal inconsistency. However, the relevant sensory connection working there is not an olfactory perception. Rather, it also is a memory cognition, which is generated out of the memory-trace of fragrance produced on the spot from the aforesaid olfactory perception. Thus, the Naiyāyikas may save their thesis of jñānalakṣaṇa pratyakṣa as well as their direct realism. (shrink)

Aesthetic judgment has often been characterized as a sensuous cognitively unmediated engagement in sensory items whether visual, auditory, haptic, olfactory or gustatory. However, new art forms challenge this assumption. At the very least, new art forms provide evidence of intention which triggers a search for meaning in the perceiver. Perceived order excites the ascription of intention. The ascription of intention employs background knowledge and experience, or in other words, implicates the perceiver’s conceptual framework. In our response to art of (...) every description we witness the incorrigible tendency in humans to construct meaningful narratives to account for events. Such meaningful narratives always implicitly involve the ascription of intention, even when the agent of the intention is not explicitly acknowledged or even clearly conceived. This principle of intention-in-order may seem incompatible with another truism which is that art is a source of novel ideas and essentially a critique of prevailing values and norms including conceptual schemes. I argue on the contrary that the human impulse to read intention in order is a precondition of art’s critical edge. Creativity is possible even though there is no raw perceptual data to which we have conscious access. That is, there are no sensory items, unmediated by the concepts we have internalized through our interaction with our communities, to which we have conscious access. (shrink)

Recurrent, unvarying, and seemingly purposeless patterns of action and cognition are part of normal development, but also feature prominently in several neuropsychiatric conditions. Repetitive stereotyped behaviors can be viewed as exaggerated forms of learned habits and frequently correlate with alterations in motor, limbic, and associative basal ganglia circuits. However, it is still unclear how altered basal ganglia feedback signals actually relate to the phenomenological variability of RSBs. Why do behaviorally overlapping phenomena sometimes require different treatment approaches−for example, sensory shielding (...) strategies versus exposure therapy for autism and obsessive-compulsive disorder, respectively? Certain clues may be found in recent models of basal ganglia function that extend well beyond action selection and motivational control, and have implications for sensorimotor integration, prediction, learning under uncertainty, as well as aesthetic learning. In this paper, we systematically compare three exemplary conditions with basal ganglia involvement, obsessive-compulsive disorder, Parkinson’s disease, and autism spectrum conditions, to gain a new understanding of RSBs. We integrate clinical observations and neuroanatomical and neurophysiological alterations with accounts employing the predictive processing framework. Based on this review, we suggest that basal ganglia feedback plays a central role in preconditioning cortical networks to anticipate self-generated, movement-related perception. In this way, basal ganglia feedback appears ideally situated to adjust the salience of sensory signals through precision weighting of new sensory information, relative to the precision of predictions based on prior generated models. Accordingly, behavioral policies may preferentially rely on new data versus existing knowledge, in a spectrum spanning between novelty and stability. RSBs may then represent compensatory or reactive responses, respectively, at the opposite ends of this spectrum. This view places an important role of aesthetic learning on basal ganglia feedback, may account for observed changes in creativity and aesthetic experience in basal ganglia disorders, is empirically testable, and may inform creative art therapies in conditions characterized by stereotyped behaviors.

Philosophers of perception have been readier to postulate the existence of a visual field than to acknowledge sensory fields in other modalities. In this paper, I argue that the set of phenomenal features that philosophers have relied on when positing a visual field aptly characterise, mutatis mutandis, bodily sensation. I argue, in particular, that in localised bodily sensations we experience the body as a sensory field. I first motivate this claim for the case of haptic touch, and then (...) generalise it to other kinds of bodily sensation. I demonstrate the theoretical fruitfulness of this notion of a bodily field for the debate on the phenomenology of bodily ownership. (shrink)

Some sensory experiences are pleasant, some unpleasant. This is a truism. But understanding what makes these experiences pleasant and unpleasant is not an easy job. Various difficulties and puzzles arise as soon as we start theorizing. There are various philosophical theories on offer that seem to give different accounts for the positive or negative affective valences of sensory experiences. In this paper, we will look at the current state of art in the philosophy of mind, present the main (...) contenders, critically compare and contrast them. In particular, we want to examine how they handle the reason-giving power of affective states. We will look into two representationalist proposals (Evaluativism and Imperativism) and a functionalist proposal, and argue that, contrary to their own advertisements, the representationalist proposals don’t have good accounts of why and how sensory affect can motivate, rationalize, and justify subsequent behavior and intentional mental activity. We will show that our own functionalist proposal does a much better job in this regard, and that when the representationalist proposals are modified to do a better job, they fare better not because of their representationalist credentials but due to their functionalist ones.

Many philosophers doubt that one can provide any successful explanation of sensory qualities - of how things look, feel, or seem to a perceiving subject. To provide such an explanation, one would need to explain qualitative facts in non-qualitative terms. Attempts to construct such explanations have seemed, in principle, doomed. Austen Clark examines the strategy used in psychophysics, psychometrics, and sensory neurophysiology to explain qualitative facts. He argues that this strategy could succeed: its structure is sound, and it (...) can answer the various philosophical objections lodged against it. On this basis Professor Clark presents an analysis of senosry qualities that offers the possibility of explaining at least some qualia, and he sketches how this scheme might eventually reduce to neurophysiology. If he is correct, we are not doomed to an eternity of mere acquaintance with our qualia. (shrink)

Do sensory measurements deserve the label of “measurement”? We argue that they do. They fit with an epistemological view of measurement held in current philosophy of science, and they face the same kinds of epistemological challenges as physical measurements do: the problem of coordination and the problem of standardization. These problems are addressed through the process of “epistemic iteration,” for all measurements. We also argue for distinguishing the problem of standardization from the problem of coordination. To exemplify our claims, (...) we draw on olfactory performance tests, especially studies linking olfactory decline to neurodegenerative disorders. (shrink)

Is the flavor of mint reducible to the minty smell, the taste, and the menthol-like coolness on the roof of one’s mouth, or does it include something over and above these—something not properly associated with any one of the contributing senses? More generally, are there features of perceptual experiences—so-called novel features—that are not associated with any of our senses taken singly? This question has received a lot of attention of late. Yet surprisingly little attention has been paid to the question (...) of what it means to say that a feature is associated with a sensory modality in the first place. Indeed, there is only one fully developed proposal in the literature, due to Casey O’Callaghan. I argue that this proposal is too permissive to inform the debate over novel features. I go on to argue that all attempts to formulate a better proposal along these lines fail. The corollary of my arguments is that the question of the existence of novel features is poorly formed. Furthermore, the problem generalizes, with the result that we should not rely on our pre-theoretical notions of the senses as the basis of theorizing about the features of perceptual experiences.

Sensory Individuals: Unimodal and Multimodal Perspectives provides an interdisciplinary, well-balanced, and comprehensive look at different aspects of unisensory and multisensory objects, using both nuanced philosophical analysis and informed empirical work. The research presented in this book represents the field's progression from treating neural sensory processes as primarily modality-specific towards its current state of the art, according to which perception, and its supporting neural processes, are multi-modal, modality-independent, meta-modal, and task-dependent. Even within such approaches sensory stimuli, properties, brain (...) activations, and corresponding perceptual phenomenology can still be characterized in a modality-specific way. The book examines the basic building blocks of human perception, and whether they are best understood as sense modality dependent units of different forms or multimodal perceptual objects. The book combines a variety of innovative and integrative angles to explore the topic and acts as a catalyst for an increasingly diverse field of research, which is in an exciting phase of growth and advancement. New questions are arising as quickly as they are being answered, and the collection Sensory Individuals provides an original and up-to-date addition to the field. (shrink)

This is the text of an invited talk exploring the connections between two apparently distinct notions of affect, sensory versus core affect. It is basically a progress report. It is exploratory and tentative. It starts from a mild puzzle about the apparent mismatch between the notion of affect that affective neuroscientists generally deploy and the notion of affect that emotion psychologists deploy. The notion favored by psychologists is the notion of core affect. The phenomenon studied by affective neuroscientists is (...) usually the notion of sensory affect. It's not clear how these two notions are related to each other. I'll present the main outlines of both notions, make some critical observations, and raise a few questions at the end. (shrink)

Philosophers of mind have distinguished (and sometimes conflated) various qualities. This article tries to sort things out.

Drawing on work in psychophysics, psychometrics, and sensory neurophysiology, Clark analyzes the character and defends the integrity of psychophysical explanations of qualitative facts, arguing that the structure of such explanations is sound and potentially successful.

As recently highlighted, despite a burgeoning field of sensory ethnography, the practices, production, and accountability of the senses in specific social interactional contexts remain sociologically under-explored. To contribute original insights to a literature on the sensuous body in physical–cultural contexts, here we adopt an ethnomethodologically sensitive perspective to focus on the accomplishment, social organization, and accountability of sensoriality in interaction. Exploring instances of the senses at work in social interaction, we utilize data from two ethnographic research projects to investigate (...) the production of running-together and swimming-together by skilled, experienced practitioners. We focus on two interlinked sensory modalities: auditory attunement, and vision and intercorporeality, identified as key dimensions of sensory embodiment and “togethering” in these particular domains.

[This is the penultimate version, please send me an email for the final version]. Some sensations are pleasant, some unpleasant, and some are neither. Furthermore, those that are pleasant or unpleasant are so to different degrees. In this essay, I want to explore what kind of a difference is the difference between these three kinds of sensations. I will develop a comprehensive three-level account of sensory pleasure that is simultaneously adverbialist, functionalist and is also a version of a satisfied (...) experiential-desire account.

When a user integrates a sensory substitution device into her life, the process involves perceptual learning, that is, ‘relatively long-lasting changes to an organism’s perceptual system that improve its ability to respond to its environment’ (Goldstone 1998: 585). In this paper, I explore ways in which the extensive literature on perceptual learning can be applied to help improve sensory substitution devices. I then use these findings to answer a philosophical question. Much of the philosophical debate surrounding sensory (...) substitution devices concerns what happens after perceptual learning occurs. In particular, should the resultant perceptual experience be classified in the substituted modality (as vision), in the substituting modality (as auditory or tactile), or in a new sense modality? I propose a novel empirical test to help resolve this philosophical debate. (shrink)

Teleological accounts of sensory normativity treat normal functioning for a species as a standard: sensory error involves departure from normal functioning for the species, i.e. sensory malfunction. Straightforward reflection on sensory trade-offs reveals that normal functioning for a species can exhibit failures of accuracy. Acknowledging these failures of accuracy is central to understanding the adaptations of a species. To make room for these errors we have to go beyond the teleological framework and invoke the notion of (...) an ideal observer from vision science. The notion of an ideal observer also sheds light on the important distinction between sensory malfunction and sensory limitation. (shrink)

Many philosophers use findings about sensory substitution devices in the grand debate about how we should individuate the senses. The big question is this: Is “vision” assisted by (tactile) sensory substitution really vision? Or is it tactile perception? Or some sui generis novel form of perception? My claim is that sensory substitution assisted “vision” is neither vision nor tactile perception, because it is not perception at all. It is mental imagery: visual mental imagery triggered by tactile (...) class='Hi'>sensory stimulation. But it is a special form of mental imagery that is triggered by corresponding sensory stimulation in a different sense modality, which I call “multimodal mental imagery.”. (shrink)

Is the brain the biological substrate of consciousness? Most naturalistic philosophers of mind have supposed that the answer must obviously be «yes » to this question. However, a growing number of philosophers working in 4e (embodied, embedded, extended, enactive) cognitive science have begun to challenge this assumption, arguing instead that consciousness supervenes on the whole embodied animal in dynamic interaction with the environment. We call views that share this claim dynamic sensorimotor theories of consciousness (DSM). Clark (2009) a founder and (...) leading proponent of the hypothesis of the extended mind, demurs, arguing that as matter of fact the biology of consciousness doesn’t allow for a brain, body and world boundary crossing architecture. We begin by looking at one of the arguments for DSM, the variable neural correlates argument. We then outline two criticisms that Clark has made of this argument and endorse his criticisms. However we finish up by using the case of sensory substitution to argue that something of this argument for DSM nevertheless survives. We suggest that Clark ought to concede sensory substitution as a case in which the conscious mind extends. (shrink)

Synaesthesia is a strange sensory blending: synaesthetes report experiences of colours or tastes associated with particular sounds or words. This volume presents new essays by scientists and philosophers exploring what such cases can tell us about the nature of perception and its boundaries with illusion and imagination.

Descartes’ accounts of sensory perception have long troubled his interpreters, for their lack of clear and explicit statements on some fundamental issues. His readers have wondered whether he allows spatial sensory ideas (spatial qualia); whether sensory ideas such as color or pain are representations and, if so, what they represent; and what cognitive value Descartes attributed to sense perception. Recent discussions take differing stands on the questions just mentioned, and also disagree over Descartes’ account of the externalization (...) of sensory qualities, on the origin and correct analysis of the “material falsity” he attributes to some sensory ideas, and on the value of the “teachings of nature.” Such disagreement should not be surprising, for although sensory perception was an important topic for Descartes, his treatment of these particular issues is not systematic – or at least not apparently so. Generally, there are no proof texts that unequivocally settle questions about Descartes’ views on spatial qualia, the representationality of sensory ideas, their cognitive value, externalization, material falsity, and the status of the teachings of nature. Yet these questions and topics naturally arise from matters about which Descartes is explicit and (reasonably) consistent, regarding the role of the senses in philosophy and everyday life and concerning the nature of minds and ideas. It is, therefore, worthwhile to ask what his positions might have been. This chapter develops answers by considering Descartes’ systematic doctrines on the nature of the mind and its ideas and by combing his statements on sensation and perception for hints about how to apply such principles. The first section reviews some key texts. Succeeding sections develop positions on representationality, cognitive value, externalization, material falsity, and the teachings of nature. Ultimately, I favor an interpretation in which, for Descartes, all sensory ideas represent by resemblance, different kinds of sensory ideas vary in cognitive value, externalization arises through spatial localization, and, with sensory ideas of color and the like, as materially false they do not intrinsically misrepresent but afford occasion for false judgments, which arise as merely apparent, and so not actually legitimate, teachings of nature.

It is typically assumed that while we know other people’s mental states by observing and interpreting their behavior, we know our own mental states by introspection, i.e., without interpreting ourselves. In his latest book, The opacity of mind: An integrative theory of self-knowledge, Peter Carruthers (2011) argues against this assumption. He holds that findings from across the cognitive sciences strongly suggest that self-knowledge of conscious propositional attitudes such as intentions, judgments, and decisions involves a swift and unconscious process of self-interpretation (...) that utilizes the same sensory channels that we employ when working out other people’s mental states. I provide an overview of Carruthers’ book before discussing a pathological case that challenges his account of self-knowledge and mentioning empirical evidence that undermines his use of a particular kind of data in his case against introspection of conscious attitudes.

David Papineau’s _The Metaphysics of Sensory Experience_ is deep, insightful, refreshingly brisk, and very readable. In it, Papineau argues that sensory experiences are intrinsic and non-relational states of subjects; that they do not essentially involve relations to worldly facts, properties, or other items (though they do happen to correlate with worldly items); and that they do not have truth conditions simply in virtue of their conscious (i.e., phenomenal) features. I am in enthusiastic agreement with the picture as described (...) so far. But Papineau also argues that sensory experiences are in no interesting sense essentially representational and that what is responsible for their truth conditions is their correlations with the environment. Here, I disagree. Indeed, I think Papineau does not follow his arguments to their proper conclusions. For if sensory experiences are intrinsic, non-relational, and only contingently correlated with worldly conditions (as Papineau and I agree they are), then the phenomenal features of sensory states are representational in an important sense: they constitute what we think, perceptually experience, or otherwise entertain, making up how things seem to us from a first-person perspective. Because of this, the truth conditions of perceptual experiences cannot be entirely independent of their phenomenal features. They cannot merely be a matter of environmental correlations. If we follow Papineau’s arguments to their proper conclusions, we end up with a view much closer to a version of representationalism that Papineau dismisses, a view he calls “pure phenomenal intentionalism”.

According to a traditional view, perceptual experiences are composites of distinct sensory and cognitive components. This dual-component theory has many benefits; in particular, it purports to offer a way forward in the debate over what kinds of properties perceptual experiences represent. On this kind of view, the issue reduces to the questions of what the sensory and cognitive components respectively represent. Here, I focus on the former topic. I propose a theory of the contents of the sensory (...) aspects of perceptual experience that provides clear criteria for identifying what kinds of properties they represent. (shrink)

Sensory substitution devices make use of one substituting modality to get access to environmental information normally accessed through another modality . Based on behavioural and neuroimaging data, some authors have claimed that using a vision-substituting device results in visual perception. Reviewing these data, we contend that this claim is untenable. We argue that the kind of information processed by a SSD is metamodal, so that it can be accessed through any sensory modality and that the phenomenology associated with (...) the use of a SSD is best described in terms of spatial phenomenology, only.

Several recent accounts claim that imagination is a matter of simulating perceptual acts. Although this point of view receives support from both phenomenological and empirical research, I claim that Jean-Paul Sartre's worry formulated in L'imagination (1936) still holds. For a number of reasons, Sartre heavily criticizes theories in which the sensory material of imaginative acts consists in reviving sensory impressions. Based on empirical and philosophical insights, this article explains how simulation theories of imagination can overcome Sartre's critique by (...) paying attention to the motor dimension of imagination. Intending to clarify the status of the sensory in imagination, a motor theory of imagination is presented in which the sensory component of imagination is interpreted in terms of anticipated sensory consequences of preparation for motor action.

Does the capacity to think require the capacity to sense? A lively debate on this topic runs throughout the history of philosophy and now animates discussions of artificial intelligence. Many have argued that AI systems such as large language models cannot think and understand if they lack sensory grounding. I argue that thought does not require sensory grounding: there can be pure thinkers who can think without any sensory capacities. As a result, the absence of sensory (...) grounding does not entail that large language models cannot think or understand. I also consider to what extent quasi-sensory grounding can at least boost the performance of a language model. (shrink)
