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)

The consensus in contemporary philosophy of mind is that how a perceptual experience represents the world to be is built into its sensory phenomenology. I defend an opposing view which I call ‘moderate separatism’, that an experience's sensory phenomenology does not determine how it represents the world to be. I argue for moderate separatism by pointing to two ordinary experiences which instantiate the same sensory phenomenology but differ with regard to their intentional content. Two experiences of (...) an object reflected in a mirror can possess the same spatial phenomenology while representing that object to occupy different spatial locations. So, contrary to the current consensus, the representation of spatial location is not fixed by an experience's sensory phenomenology. (shrink)

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”.

The senses present their content in the form of images, three-dimensional arrays of located sense features. Peacocke’s “scenario content” is one attempt to capture image content; here, a richer notion is presented, sensory images include located objects and features predicated of them. It is argued that our grasp of the meaning of these images implies that they have propositional content. Two problems concerning image content are explored. The first is that even on an enriched (...) conception, image content has certain expressive limitations. In particular, it cannot express absolute location and time (as opposed to spatiotemporal relations) or logical complexity. Yet, perceptual experience does seem to express certain absolute locations—namely, here and now. How can it do so? Secondly, image content cannot exhaust the significance of perceptual states. This is proved by noting that perception, memory, and anticipation can have the same image content. Yet they have different significance. These problems show that some of the significance of sensory states comes from outside the image. (shrink)

Almost any mainstream reading about the nature of Kant's 'content of cognition' in both non-conceptualist and conceptualist camps agree that 'singular representations' (sensible intuitions) are, at least in some weak sense, objectdependent because they supervene on a manifold of sensations that are given through the disposition of our sensibility and parallel thus the real and physical components of the world (cf. McDowell 1996, Allison 1983, Ginsborg 2008, Allais 2009). The relevant class of sensible intuitions should refer, as they argue, (...) only to empirical and not to pure ones. Kant's transcendental argument creates, however, no implications as to the metaphysics of properties. Neither does he consider the world to be consisted of sensory content simpliciter nor do sensations refer to objects per se. Instead, he provides an all-encompassing pattern for sensible intuitions of any kind through the representation of space as a cognitive map in that an object can be represented if spatial properties are attributed to it. Sensible intuitions of any kind could be referring, that is to say, and can be conceptualized if they are spatial. Consequently and unlike the contemporary philosophy of perception, Kant contrasts sensible intuitions and pure concepts of understanding 'altogether' against one single experience, from which the justification of objects should proceed. In other words, what stands at the core of exposing the content of cognition concerns not the phenomenological status and actuality of sensible intuitions in the sense of 'bits of experiential intake', but the logical structure of possibility of sensible intuitions of any (external or internal) causal background. The aim of this discussion is to clarify that Kant's transcendental idealism mutatis mutandis reviews multiple and diverse kinds of 'data of mind' and cognition in the background, without reducing the content of cognition to metaphysically determined referents as 'matters of fact' and to pure concepts of understanding. Sensible intuitions in the sense of content of cognition vary, most importantly, from unstructured and unjustifiable data of mind including (physical) contents of perception and stuff of mind and also from reflective and intellectual intuitions that are the cognates of the structured complex singular representations. Put it in simple terms, Kant advocates the thesis that 'facts' are objects for concepts if they are already well-founded trough the cognitive map of the representation of space. -/- . (shrink)

Intermodal representationalists hold that the phenomenal characters of experiences are fully determined by their contents. In contrast, intramodal representationalists hold that the phenomenal characters of experiences are determined by their contents together with their intentional modes or manners of representation, which are nonrepresentational features corresponding roughly to the sensory modalities. This paper discusses a kind of experience that provides evidence for an intermodal representationalist view: intermodal experiences, experiences that unify experiences in different modalities. I argue that such experiences are (...) much easier to explain on the intermodal view. (shrink)

I develop several new arguments against claims about "cognitive phenomenology" and its alleged role in grounding thought content. My arguments concern "absent cognitive qualia cases", "altered cognitive qualia cases", and "disembodied cognitive qualia cases". However, at the end, I sketch a positive theory of the role of phenomenology in grounding content, drawing on David Lewis's work on intentionality. I suggest that within Lewis's theory the subject's total evidence plays the central role in fixing mental content and ruling (...) out deviant interpretations. However I point out a huge unnoticed problem, the problem of evidence: Lewis really has no theory of sensory content and hence no theory of what fixes evidence. I suggest a way of plugging this hole in Lewis's theory. On the resulting theory, which I call " phenomenal functionalism", there is a sense in which sensory phenomenology is the source of all determinate intentionality. Phenomenal functionalism has similarities to the theories of Chalmers and Schwitzgebel. (shrink)

Philosophers of perception widely agree that sensory properties, like color, are represented in perceptual experience. Arguments are usually needed to establish that something other than sensory properties, for example three-dimensional objects or kind properties, are part of perceptual content. Call the idea that sensory properties are represented in perceptual experience the Sensation View (SV). Given its widespread acceptance, we may expect to find strong reasons for holding SV. In this paper, I argue that we lack such (...) reasons: SV is largely unjustified. We have surprisingly poor justification for thinking that sensory properties are represented in perception. By focusing on the case of vision, I show that an embedded understanding of visual perception, and empirical evidence in cognitive psychology, indicate that SV is far from warranted. (shrink)

[Late draft.] The paper examines the roles that may be played by sensory images in relation to the contents of sensory memories. It argues that the images may serve either simply to characterise putative past states of the world or to capture putative past sensory experiences of the subject. It uses the resulting account to shed light on various phenomena involving sensory memories, such as the status of 'observer memories'.

Philosophers debate whether all, some or none of the represcntational content of our sensory experience is conccptual, but the technical term "concept" has different uses. It is commonly linked more or less closely with the notions of judgdment and reasoning, but that leaves open the possibility that these terms share a systematic ambiguity or indeterminacy. Donald Davidson, however, holds an unequivocal and consistent, if paradoxical view that there are strictly speaking no psychological states with representational or intentional (...) class='Hi'>content except the propositional attitudes of language users, since thc source or fundamental bearer of intentionality is the employed sentence. Accordingly he claims that what has content in ordinary sense experience is not sensation, but propositional belief caused, but not justified, by sensation. John McDowell, sharing some ofDavidson's premises,holds a less paradoxical, but (l will argue) equivocal and incoherent view that post-infantile human sensory expcrience must have content in so far as it is what grounds perceptual belief but that this content is itself conceptual or propositional, dependent on language and culture. Reasons are givcn in the present article for rejecting both views, and their common premises. It is argued that perceptual or sensory states have intentional content which is no more conceptual or propositional than the world is. Recognition that perceptual content and conceptual content are, in a certain unsurprising way incommensurable allows for a more realistic understanding of the relationship between Language and the world as we experience it.

Philosophical discussion about the reality of sensory perceptions has been hijacked by two tendencies. First, talk about perception has been largely centered on vision. Second, the realism question is traditionally approached by attaching objects or material structures to matching contents of sensory perceptions. These tendencies have resulted in an argumentative impasse between realists and anti-realists, discussing the reliability of means by which the supposed causal information transfer from object to perceiver takes place. Concerning the nature of sensory (...) experiences and their capacity to provide access to reality, this article challenges the standard categories through which most arguments in this debate have been framed to date. Drawing on the underexplored case of olfaction, I first show how the details of the perception process determine the modalities of sensory experiences. I specifically examine the role of measurement and analyze its influence on the characterization of perceptions in olfaction. My aim is to argue for an understanding of perception through a process view, rather than one pertaining to objects and properties of objects. (shrink)

Central to Sellars’ account of human cognition was a clear distinction, expressed in varying terminology in his different works, “between conceptual and nonconceptual representations.” Those who have come to be known as ‘left-wing Sellarsians’, such as Richard Rorty, Robert Brandom, and John McDowell, have tended to reject Sellars’ appeals to nonconceptual sensory representations. So-called ‘right-wing Sellarsians’ such as Ruth Millikan and Jay Rosenberg, on the other hand, have embraced and developed aspects of Sellars’ account, in particular the central underlying (...) idea that human perceptual cognition involves a certain naturalistic ‘mapping’ correspondence or structural ‘picturing’ isomorphism between internal mental representations and the layout and behavior of objects in the surrounding environment. Sellars, despite his defenses of nonconceptual representational content throughout his career, has with no small irony come to be cited as one of the “founding fathers of conceptualism.” While recognizing the strong conceptualist elements in Sellars’ Kantian account of perceptual cognition, I argue that a central core of Sellars’ account of nonconceptual sensory contents does not by itself fall afoul of the philosophical worries raised by the left-leaning Sellarsians, and that in fact it has significant merits in its own right.

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.

Malebranche holds that sensory experience represents the world from the body’s point of view. I argue that Malebranche gives a systematic analysis of this bodily perspective in terms of the claim that the five familiar external senses and bodily awareness represent nothing but relations to the body.

According to “intentionalist” interpretations of Kant’s transcendental idealism, Kant’s empirical objects are to be understood as mere intentional objects. This interpretation requires a corresponding account of intentionality and intentional objects. This paper defends an account of how the intentionalist should understand the intentional structures at work in the sensory consciousness of physical bodies. First a relational conception of intentionality (articulated in terms of an object’s presence to consciousness) is distinguished from a non-relational conception (articulated in terms of representational (...) class='Hi'>content). I argue that the intentionalist’s claim that Kant’s empirical objects are mere intentional objects is primarily a claim about non-relational intentionality. I then ask whether the intentionalist should also recognize a role for relational intentionality as well. After rejecting two possible answers (that there is no relational intentionality, or that there are intentional relations to things in themselves), I argue that sensory consciousness involves having spatially arrayed collections of sensations presented to consciousness in intuition, and then conceptualizing these sensation-arrays as physical objects. The obvious worry about such a phenomenalist interpretation has to do with the consistency of this interpretation with Kant’s empirical realism; these concerns are addressed in detail in the final section.

Recent philosophy of mind has seen an increase of interest in theories of intentionality in offering a functional account of mental states. The standard intentionalist view holds that mental states can be exhaustively accounted for in terms of their representational contents. An alternative view proposed by Tim Crane, called impure intentionalism, specifies mental states in terms of intentional content, mode, and object. This view is also suggested to hold for states of sensory awareness. This paper primarily develops an (...) alternative to the impure intentionalist account of states of sensory awareness. On the basis of Husserl’s phenomenological work, I argue that a focus on intentionality at the level of sensory awareness is phenomenologically implausible. The final part offers an alternative functional account of sensory awareness based on what Husserl called ‘immanent association’. (shrink)

Based on but not limited to material from a conference at Brown University in 2011, Sensory Integration and the Unity of Consciousness is an ambitious collection that brings together two distinct but inter- twined topics.1 In what follows, I briefly explain what sensory integration and the unity of conscious- ness amount to, highlight the contents of the papers, and finally end with general observations and suggestions. I will spend more time on sensory integration, since it is relatively (...) unfamiliar terrain in philosophy. (shrink)

Most of those who hold that emotions involve appraisals also accept that the content of emotions is nonconceptual. The main motivation for nonconceptulism regarding emotions is that it accounts for the difference between emotions and evaluative judgements. This paper argues that if one assumes a broadly Fregean account of concepts, there are good reasons to accept that emotions have nonconceptual contents. All the main arguments for nonconceptualism regarding sensory perception easily transpose to the case of emotions. The paper (...) ends by responding to two important objections: firstly, that nonconceptualism rules out the possibility that emotions justify evaluative judgements and secondly, that nonconceptualism cannot account for the fact that some emotions have conceptually articulated cognitive bases.

Success semantics holds, roughly, that what it is for a state of an agent to be a belief that P is for it to be disposed to combine with her desires to cause behaviour that would fulfill those desires if P. J. T. Whyte supplements this with an account of the contents of an agent's “basic desires” to provide an attractive naturalistic theory of mental content. We argue that Whyte's strategy can avoid the objections raised against it by restricting (...) “basic desires” to sensory inclinations that cause us to do things independently of our beliefs about their contents. -/- La sémantique du succès soutient, en gros, que ce qu'il faut pour qu'un état d'un agent soit une croyance en P, c'est que cet état soit disposé à se combiner avec ses désirs pour provoquer un comportement qui répondrait à ces désirs si P. J. T. Whyte complète cela par un compte-rendu du contenu des « désirs de base » d'un agent pour fournir une théorie naturaliste attrayante du contenu mental. Nous soutenons que la stratégie de Whyte peut éviter les objections qui lui sont faites en restreignant les « désirs de base » aux inclinations sensorielles qui nous font agir indépendamment de nos croyances sur leur contenu.

This report highlights and explores five questions that arose from the Network for Sensory Research workshop on perceptual learning and perceptual recognition at the University of York on March 19th and 20th, 2012: 1. What is perceptual learning? 2. Can perceptual experience be modified by reason? 3. How does perceptual learning alter perceptual phenomenology? 4. How does perceptual learning alter the contents of perception? 5. How is perceptual learning coordinated with action?

Here I propose an interpretation of the ancient Stoic psychological theory on which (i) the concepts that an adult human possesses affect the content of the perceptual impressions (φαντασίαι αἰσθητικαί) she forms, and (ii) the content of such impressions is exhausted by an ‘assertible’ (ἀξίωμα) of suitable complexity. What leads the Stoics to accept (i) and (ii), I argue, is their theory of assent and belief formation, which requires that the perceptual impression communicate information suitable to serve as (...) the content of belief. In arguing for (i), I reject a rival interpretation on which conceptualization occurs subsequently to the formation of a perceptual impression. In arguing for (ii), I deny that perceptual impressions have two kinds of content: one formulated in an assertible, the other sensory, featuring independently of this assertible. I explore the implications of (i) and (ii) for the Stoic theory of emotions, expertise, and rationality, and argue that they shed new light on the workings of impression, assent, and belief.

A straightforward way of thinking about perception is in terms of perceptual representation. Perception is the construction of perceptual representations that represent the world correctly or incorrectly. This way of thinking about perception has been questioned recently by those who deny that there are perceptual representations. This article examines some reasons for and against the concept of perceptual representation and explores some potential ways of resolving this debate. Then it analyzes what perceptual representations may be: if they attribute properties to (...) entities, what are these attributed properties, and what are the entities they are attributed to.

Many currently working on a Russellian notion of perceptual acquaintance and its role in perceptual experience (including Campbell 2002a, 2002b, and 2009 and Tye 2009) treat naïve realism and indirect realism as an exhaustive disjunction of possible views. In this paper, I propose a form of direct realism according to which one is directly aware of external objects and their features without perceiving a mind-dependent intermediary and without making any inference. Nevertheless, it also maintains that the qualitative character of perceptual (...) experience is a feature of our internal states of sentient awareness and so is to be distinguished from the features of objects in the perceptual scene. On this proposal, we are pre-reflectively aware of the qualitative character of our sensations simply in virtue of having them, and we are non-inferentially aware of external objects and their features by being attuned to what the occurrence of our sensations tells us about the rest of the world. Consequently, we are presented with, and thus acquainted with, both the external objects and the qualitative character of our sensory experiences, albeit in very different ways. Drawing on resources from Perry (2001) and Searle (in draft), I explain how perceptual experience has this “two-faced presentational character”. (shrink)

Klein, Nguyen, & Zhang (in press) argued that the evolutionary transition from respondent to agent during the Cambrian Explosion would be a promising vantage point from which to gain insight into the evolution of organic sentience. They focused on how increased competition for resources -- in consequence of the proliferation of new, neurally sophisticated life-forms -- made awareness of the external world (in the service of agentic acts) an adaptive priority. The explanatory scope of Klein et al (in press) was (...) limited to consideration of the conscious apprehension of externally sourced content – i.e., content delivered from the sensory registration of objects occupying phenomenal space. But consciousness – at least for humans -- takes its objects from internal as well as external sources. In the present article we extend their analysis to the question of how internally sourced content (i.e., mental states) became the object of conscious apprehension. (shrink)

Bodily awareness seems to present the body as a topologically connected whole, composed of many parts. In consequence, the source of topological and mereological content of bodily awareness comes into question. In particular, it may be asked whether (a) such content is provided by the bodily sense, i.e., sensory mechanisms which, like proprioception, presents the body “from the inside,” or (b) it is a product of “exteroceptive” elements of bodily awareness, which represents the body “from the outside” (...) in a similar way to that of other physical objects. This paper argues that while passive touch and proprioception are unlikely to present the body as a topological and a mereological whole, such content is likely to be provided by kinesthesis. In consequence, it is plausible that holistic topological and mereological bodily content is present in virtue of certain mechanisms of bodily sense. (shrink)

In this paper we address the question of what determines the content of our conscious episodes of thinking, considering recent claims that phenomenal character individuates thought contents. We present one prominent way for defenders of phenomenal intentionality to develop that view and then examine ‘sensory inner speech views’, which provide an alternative way of accounting for thought-content determinacy. We argue that such views fare well with inner speech thinking but have problems accounting for unsymbolized thinking. Within this (...) dialectic, we present an account of the nature of unsymbolized thinking that accords with and can be seen as a continuation of the activity of inner speech, while offering a way of explaining thought-content determinacy in terms of linguistic structures and representations. (shrink)

A central question, if not the central question, of philosophy of perception is whether sensory states have a nature similar to thoughts about the world, whether they are essentially representational. According to the content view, at least some of our sensory states are, at their core, representations with contents that are either accurate or inaccurate. Tyler Burge’s Origins of Objectivity is the most sustained and sophisticated defense of the content view to date. His defense of the (...) view is problematic in several ways. The most significant problem is that his approach does not sit well with mainstream perceptual psychology. (shrink)

It is clear that visual imagery is somehow significantly visual. Some theorists, like Kosslyn, claim that the visual nature of visualisations derives from features of the neural processes which underlie those episodes. Pylyshyn claims, however, that it may merely reflect special features of the contents which we grasp when we visualise things. This paper discusses and rejects Pylyshyn's own attempts to identify the respects in which the contents of visualisations are notably visual. It then offers a novel and very different (...) account of what is distinctively sensory about the contents of sensory images. The paper's alternative account is used in explaining various pieces of phenomenological and behavioural data concerning visualisation. Finally, it is tentatively suggested that the proposed account of the contents of sensory images may also shed light upon some of the neurological data involving visualisation and sensory imagery more generally.

Drawing on ideas from philosophy (in particular, epistemology), I argue that one of memory’s most important functions is to provide its owner with knowledge of the physical world. This knowledge helps satisfy the organism’s need to confer stability on an ever-changing reality so the objects in which it consists can be identified and reidentified. I then draw a distinction between sources of knowledge (i.e., from physical vs. subjective reality) and argue—based on evolutionary principles—that because memory was designed by natural selection (...) to interface with the physical world, knowledge acquired via sensory/perceptual experiences should be better remembered than internally generated knowledge made available by introspection. A study conducted to test this hypothesis provides support. I conclude that a serious interdisciplinary approach to issues typically considered the purview of psychology best enables researchers to craft well-specified, theoretically based hypotheses that directly target functions of the mind.

The first premise of Schellenberg’s particularity argument reads, “If a subject S perceives a particular α, then S discriminates and singles out α” (2018: 25). But this is false if seeing a ganzfeld is possible (i.e., a homogeneous field without any particulars to discriminate). In response, Schellenberg argues that seeing a ganzfeld is impossible by appealing to the ganzfeld effect (viz. hallucinatory experiences caused by ganzfeld exposure) exclusively as a ‘sense of blindness’. I present two challenges for this line of (...) reasoning. The first concerns the need to account for the long delay before blindness is reported (if it is reported at all) and the second concerns the need to be consistent with potential causes of ganzfeld hallucinations (in general, not exclusive to the sense of blindness). I show how Schellenberg’s particularity argument can meet the first challenge but struggles to meet the second. I present evidence based on considerations related to sensory deprivation and that follow from the predictive processing theory of cognition, which describes seeing a ganzfeld as the cause of ganzfeld hallucinations. If correct, this means that you can see a homogeneous field, and thus we ought to be skeptical of the soundness of Schellenberg’s particularity argument. I conclude with a possible strategy for rehabilitating the particularity argument that reconceptualizes perceptual experience as fundamentally multimodal, constituted by both exteroceptive and interoceptive sensation.

Does inner sense, like outer sense, provide inner sensations or, in other words, a sensory manifold of its own? Advocates of the disparity thesis on inner and outer sense claim that it does not. This interpretation, which is dominant in the preexisting literature, leads to several inconsistencies when applied to Kant’s doctrine of inner experience. Yet, while so, the parity thesis, which is the contrasting view, is also unable to provide a convincing interpretation of inner sensations. In this paper, (...) I argue that this deadlock can be traced back to an inadequate understanding of inner sense shared by both sides. Drawing upon an analysis of the notion of obscure representations, I offer an alternative interpretation of inner sense with a special regard to self-affection, apprehension, and attention. From this basis, I will infer that outer sense delivers sensory content that is initially and intrinsically unaccompanied by phenomenal consciousness; inner sense contributes by endowing such content with phenomenal consciousness. Therefore, phenomenal qualities can be regarded as the sensory manifold of inner sense. This alternative interpretation solves the long-standing dispute concerning inner sensations and would further illuminate Kant’s notion of inner experience. (shrink)

Evaluativism about unpleasant pains offers one way to think about unpleasant pain experience. However, extant Evaluativist views do not pay enough attention to the affective dimension of pain experience and the complex relations between the affective, evaluative and sensory dimensions. This paper clarifies these relations and provides a view which more closely reflects the phenomenology of unpleasant pains. It argues that the intentional structure of paradigmatic unpleasant pain is as follows: unpleasant pains essentially involve a proprietary intentional mode—what I (...) call affective-interoception—and a distinctive kind of evaluatively qualified sensory content. The resulting view is Affective-Evaluativism. (shrink)

The point of this paper is to reveal a dogma in the ordinary conception of sensory imagination, and to suggest another way forward. The dogma springs from two main sources: a too close comparison of mental imagery to perceptual experience, and a too strong division between mental imagery and the traditional propositional attitudes (such as belief and desire). The result is an unworkable conception of the correctness conditions of sensory imaginings—one lacking any link between the conditions under which (...) an imagining aids human action and inference and the conditions under which it is veridical. The proposed solution is, first, to posit a variety of imaginative attitudes—akin to the traditional propositional attitudes—which have different associated correctness (or satisfaction) conditions. The second part of the solution is to allow for imaginings with “hybrid” contents, in the sense that both mental images and representations with language-like constituent structure contribute to the content of imaginings. (shrink)

The sensory constraint on conscious thought says that if a thought is phenomenally conscious, its phenomenal properties must be reducible to some sensory phenomenal character. I argue that the burgeoning psychological literature on aphantasia, an impoverishment in the ability to generate mental imagery, provides a counterexample to the sensory constraint. The best explanation of aphantasics’ introspective reports, neuroimaging, and task performance is that some aphantasics have conscious thoughts without sensory mental imagery. This argument against the (...) class='Hi'>sensory constraint supports the existence of a non-sensory phenomenology of thought. Moreover, this argument can be extended to show that this non-sensory phenomenology determines a thought content. Finally, it can potentially diagnose the disagreement over cognitive phenomenology in the philosophy of mind, as such disagreement may turn on interpersonal variation in mental imagery. (shrink)

If imagination is subject to the will, in the sense that people choose the content of their own imaginings, how is it that one nevertheless can learn from what one imagines? This chapter argues for a way forward in addressing this perennial puzzle, both with respect to propositional imagination and sensory imagination. Making progress requires looking carefully at the interplay between one’s intentions and various kinds of constraints that may be operative in the generation of imaginings. Lessons are (...) drawn from the existing literature on propositional imagination and from the control theory literature concerning the prediction and comparison mechanisms (or “forward models”) involved in ordinary perception. A more general conclusion is reached that, once we have the tools to understand how some imaginings are both under willful control and helpfully guide action and inference, we will have what we need to understand the cognitive basis of imagination in general.

Some have defended a Fregean view of perceptual content. On this view, the constituents of perceptual contents are Fregean modes of presentation (MOPs). In this paper, I propose that perceptual MOPs are best understood in terms of object files. Object files are episodic representations that store perceptual information about objects. This information is updated when sensory conditions change. On the proposed view, when a subject perceptually represents some object a under two distinct MOPs, then the subject initiates two (...) object files that both refer to a. My defense of this view appeals to its satisfaction of four constraints that I argue theories of perceptual MOPs should satisfy. Furthermore, I show that some existent accounts of perceptual MOPs fail to satisfy them. The defended constraints also indicate what is unique about perceptual, as opposed to linguistic or cognitive, MOPs. (shrink)

It has long been recognized that we have a great deal of freedom to imagine what we choose. This paper explores a thesis—what we call “intentionalism (about the imagination)”—that provides a way of making this evident (if vague) truism precise. According to intentionalism, the contents of your imaginings are simply determined by whatever contents you intend to imagine. Thus, for example, when you visualize a building and intend it to be of King’s College rather than a replica of the college (...) you have imagined the former rather than the latter because you intended to imagine King’s College. This is so even if the visual image you conjure up equally resembles either. This paper proposes two kinds of counterexamples to intentionalism and discusses their significance. In particular, it sketches a positive account of how many sensory imaginings get to be about what they are about, which explains how the causal history of our mental imagery can prevent us from succeeding in imagining what we intended.

In The Metaphysics of Sensory Experience, David Papineau offers some metaphysical reasons for rejecting representationalism. This paper overviews these reasons, arguing that while some of his arguments against some versions of representationalism succeed, there are versions of phenomenal intentionalism that escape his criticisms. Still, once we consider some of the contents of perceptual experiences, such as their perspectival contents, it is clear that perceptual experience does not present us with the world as we take it to be. This leads (...) to a rather attenuated form of representationalism, perhaps one that even Papineau could come close to agreeing with. (shrink)

Christopher Gauker argues that no concept can be extracted from perceptual experience and that imagistic thought cannot draw boundaries between one kind and another. Here, it is argued, on the contrary, that images have extension and are consequently Fregean concepts. Hume’s theory of abstraction as indifference is offered as an account of extra-sensory concepts. Finally, it is argued that modern theories of sensory data processing run parallel to Kant’s idea of synthesis as a pre-condition for perception.

Often, sensory input underdetermines perception. One such example is the perception of illusory contours. In illusory contour perception, the content of the percept includes the presence of a contour that is absent from the informational content of the sensation. (By “sensation” I mean merely information-bearing events at the transducer level. I intend no further commitment such as the identification of sensations with qualia.) I call instances of perception underdetermined by sensation “underdetermined perception.” The perception of illusory contours (...) is just one kind of underdetermined perception. The focus of this chapter is another kind of underdetermined perception: what I shall call "active perception". Active perception occurs in cases in which the percept, while underdetermined by sensation, is determined by a combination of sensation and action. The phenomenon of active perception has been used by several to argue against the positing of representations in explanations of sensory experience, either by arguing that no representations need be posited or that far fewer than previously thought need be posited. Such views include, but are not limited to those of Gibson (1966, 1986), Churchland. (shrink)

This paper proposes a methodological strategy to investigate the question of the individuation of the senses both from a commonsensical and a scientific point of view. We start by discussing some traditional and recent criteria for distinguishing the senses and argue that none of them taken in isolation seems to be able to handle both points of views. We then pay close attention to the faculty of hearing which offers promising examples of the strategy we pursue of combining commonsense and (...) science. In particular, we argue in favour of a distinction between two kinds of modes of presentation associated with sound perception: a mechanical mode of presentation that makes sounds perceptible by other modalities than audition such as touch and a tonal mode of presentation that makes people conceive of sounds as the proper objects of auditory perception.

In Sense and Content , Christopher Peacocke points out that two equally-sized trees at different distances from the perceiver are normally represented to be the same size, despite the fact that in a certain sense the nearer tree looks bigger ; he concludes on the basis of this observation that visual experiences possess irreducibly phenomenal properties. This argument has received the most attention of all of Peacocke’s arguments for separatism—the view that the intentional and phenomenal properties of experiences are (...) independent of one another. However, despite its notoriety, the argument is widely misunderstood and underappreciated. I argue that once the structure of the argument is clarified and the replies that have been offered are considered closely, one must conclude that the trees argument is successful. (shrink)

Memory seems intuitively to consist in the preservation of some proposition (in the case of semantic memory) or sensory image (in the case of episodic memory). However, this intuition faces fatal difficulties. Semantic memory has to be updated to reflect the passage of time: it is not just preservation. And episodic memory can occur in a format (the observer perspective) in which the remembered image is different from the original sensory image. These difficulties indicate that memory cannot be (...) preserved content. It is proposed that what is preserved in memory isan underlying "trace", and that in every act of remembering, memorial content is reconstructed from the preserved trace. (shrink)

The chapter focuses on attributions of the transparency of thought to early modern figures, most notably Descartes. Many recent philosophers assume that Descartes believed the mind to be “transparent”: since all mental states are conscious, we are therefore aware of them all, and indeed incorrigibly know them all. Descartes, and Berkeley too, do make statements that seem to endorse both aspects of the transparency theses (awareness of all mental states; incorrigibility). However, they also make systematic theoretical statements that directly countenance (...) “unnoticed” thoughts or mental states, that is, thoughts or mental states of which the subject is unaware and has no knowledge. Descartes, having identified the essence of mind with thought or representation, distinguishes bare states of mind from states of which we have reflective awareness, thereby providing a theoretical tool for understanding both his seeming endorsement of transparency and his actual denial of it: Descartes distinguished between a basic perceptual state, or a basic awareness, and reflectively conscious states that involve explicit noticing and cognizing on the part of the subject. Leibniz (as is better known) directly endorsed a similar distinction between bare perception and reflective consciousness, using the term “perception” for the first and “apperception” for the second. In these cases, bare perceptions are not transparently available to the subject, and so in fact the subject does not have knowledge, hence does not have incorrigible knowledge, of all its occurrent mental states. This chapter gives evidence to support these claims; elaborates the complex psychology of the subject found in Descartes and other early moderns; and notes some ways in which these early moderns contributed to the genesis of the modern subject. Finally, it compares McDowell’s conception of the Cartesian mind with the conceptions of mind found in the writings of Descartes, Berkeley, and Leibniz, finding that his characterization caricatures the positions of early modern philosophers. McDowell's characterization has four elements: consciousness as essence of mind; intentionality as exclusively mental; the veil of perception; and the transparency of mind. Only the second point, about intentionality, fully fits Descartes. As a consequence of his own misdirection, McDowell misses the actual basis of his difficulty in connecting mind with world, which arises from a point of agreement between him and Descartes: the removal of intentionality from material sensory systems. But whereas Descartes could relocate (nonconceptual) sensory intentionality in mental states, McDowell is left to account for it with his overly cognitivized scheme of perceptual content as exclusively conceptual.

It is part of the phenomenology of perceptual experiences that objects seem to be presented to us. The first guide to objects is their perceptual presence. Further reflection shows that we take the objects of our perceptual experiences to be among the causes of our experiences. However, not all causes of the experience are also objects of the experience. This raises the question indicated in the title of this paper. We argue that taking phenomenal presence as the guide to the (...) objects of perception, we can see that at least in two sensory modalities, smell and touch, there is no uniform answer to this question. The objects of olfactory and tactile experiences can move along the causal chain. Accordingly, the content of olfactory and tactile experience may vary. (shrink)

We present a theoretical view of the cellular foundations for network-level processes involved in producing our conscious experience. Inputs to apical synapses in layer 1 of a large subset of neocortical cells are summed at an integration zone near the top of their apical trunk. These inputs come from diverse sources and provide a context within which the transmission of information abstracted from sensory input to their basal and perisomatic synapses can be amplified when relevant. We argue that apical (...) amplification enables conscious perceptual experience and makes it more flexible, and thus more adaptive, by being sensitive to context. Apical amplification provides a possible mechanism for recurrent processing theory that avoids strong loops. It makes the broadcasting hypothesized by global neuronal workspace theories feasible while preserving the distinct contributions of the individual cells receiving the broadcast. It also provides mechanisms that contribute to the holistic aspects of integrated information theory. As apical amplification is highly dependent on cholinergic, aminergic, and other neuromodulators, it relates the specific contents of conscious experience to global mental states and to fluctuations in arousal when awake. We conclude that apical dendrites provide a cellular mechanism for the context-sensitive selective amplification that is a cardinal prerequisite of conscious perception. (shrink)

Radical enactivists claim that cognition is split in two distinct kinds, which can be differentiated by how they relate to mental content. In their view, basic cognitive activities involve no mental content whatsoever, whereas linguistically scaffolded, non-basic, cognitive activities constitutively involve the manipulation of mental contents. Here, I evaluate how this dichotomy applies to imagination, arguing that the sensory images involved in basic acts of imaginations qualify as vehicles of content, contrary to what radical enactivists claim. (...) To argue so, I leverage what has appropriately been dubbed a “compare to prototype” argument. Hence, I will first identify, within the enactivist literature, the general functional profile of a vehicle of content complying with the austere standard of contentfulness radical enactivists adhere to. Provided such a profile, I will show, relying on a mixture of reasoning and empirical evidence, that basic sensory images satisfy it, and thus that they can rightfully be identified as vehicles of content. This, I claim, provides a sufficient reason to identify the sensory images involved in basic acts of imagination as vehicles of content, thereby denying that basic imagination does not involve mental content.

The proper sensible criterion of sensory individuation holds that senses are individuated by the special kind of sensibles on which they exclusively bear about (colors for sight, sounds for hearing, etc.). H. P. Grice objected to the proper sensibles criterion that it cannot account for the phenomenal difference between feeling and seeing shapes or other common sensibles. That paper advances a novel answer to Grice's objection. Admittedly, the upholder of the proper sensible criterion must bind the proper sensibles –i.e. (...) colors– to the common sensibles –i.e. shapes– so as to account for the visual phenomenal character of shapes. But, as Grice rightly objected, neither association, nor ontological dependence will do –I spend some time isolating why dependence is a bad answer here, basically because the dependence of shape on colors is generic, and that genericity is arguably not part of the phenomenal content of perception. -/- Grice is wrong, however, to think that once association and dependence have been rebutted, there is no other way to attach color to extension. The right way to connect proper and common sensibles is rather trivial, although it seems to have been widely neglected: proper sensibles FILL common ones. To see a shape, by contrast to feeling it, is to perceived as filled by some color. To feel a shape, is to perceive it as, say, filled by pressure. Filling in is the phenomenal connection between proper and common sensibles. -/- One important corollary of that proposal is that proper sensibles –color, pressure, noise, taste...– have to belong to the category of stuffs, in the sense of uncountable entities. Against the widespread view that colors are properties, which have countable instances, the last part of the paper argues that colors are phenomenal stuffs, which fill some visual area. One commits a category mistake in asking: "How many tropes/instances of this determinate redness is there on that ladybird". One should rather ask "How much of this determinate redness is there on that ladybird". (shrink)
