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.

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.

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)

“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)

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)

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)

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)

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.

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.

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)

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)

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.

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.

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)

In the paper, I argue that the notion of sensory representation that Pautz defines (via the Ramsey method) has incompatible features. The notion is defined in terms of its ability to explain both the phenomenal character of experience and its ability to give us cognitive access to perceptible properties, all while being existence-neutral. I argue that there is strong reason to conclude that no worldly relation could play all three roles simultaneously.

A recent report by Persaud et al. [Persaud, N., McLeod, P. & Cowey, A. . Post-decision wagering objectively measures awareness. Nature Neuroscience 10, 257–261] addresses a fundamental issue in consciousness science: the experimental measurement of conscious content. The authors propose a novel technique, ‘post-decision wagering’, in which subjects place bets on the correctness of decisions or discriminations. In this note, I critique the authors’ claim that their method “measures awareness directly”.

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.

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)

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)

In the nearly half a century since its modern inception (Anscombe (1965), Hintikka (1969)), the Representation theory has faced no more implacable enemy than Ned Block. He has offered objection after objection, usually in the form of apparent counterexamples, and as I write this he shows no sign of flagging.

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)

It is hoped that modern sensory substitution and augmentation devices will be able to replace or expand our senses. But to what extent has this been achieved to date? To what extent are the experiences created by sensory substitution devices like the sensory experiences that we are trying to replace? To what extent can we augment people’s senses providing them with new information and new experiences? The first aim of this introduction is to delve deeply into this (...) question to discover the usefulness of these devices, to outline the different sorts of experience that might be created, and what the evidence tells us about these experiences. While there are some reasons to be hopeful about the powers of sensory substitution devices, there are also reasons to wonder whether they will ever really have the practical applications that we hope they might have. The second aim is to look to see whether the study of modern sensory substitution and augmentation devices can shed light on the nature of our senses and perception in general. Much of the philosophical, psychological, and neuroscientific work that takes place concerning sensory substitution and augmentation is keenly aware of the possibility that it might help our understanding and it seeks to comprehend many different aspects of perception.
