The paper presents a new theory of perceptual demonstrative thought, the property-dependent theory. It argues that the theory is superior to both the object-dependent theory (Evans, McDowell) and the object-independent theory (Burge).

The target article argues that language-of-thought hypothesis (LoTH) is applicable to various domains, including perception. However, it focusses exclusively on the visual case, which is limited in this regard. I argue for two ideas in this commentary: first, their case can be extended to other modalities such as touch; and second, the status of those six criteria needs to be further clarified.

Demonstrative thoughts are distinguished by the fact that their contents are determined relationally, via perception, rather than descriptively. Therefore, a fundamental task of a theory of demonstrative thought is to elucidate how facts about visual perception can explain how these thoughts come to have the contents that they do. The purpose of this paper is to investigate how cognitive psychology may help us solve this metasemantic question, through empirical models of visual processing. Although there is a dispute between attentional and (...) non-attentional models concerning the best metasemantic mechanism for demonstrative thoughts, in this paper I will argue in favor of a hybrid model, which combines both types of processes. In this picture, attentional and non-attentional mechanisms are not mutually exclusive, and each plays a specific role in determining the singular content of demonstrative thoughts. (shrink)

Attention plays a role in demonstrative thought: It sets the targets. Visual experience also plays a role. I argue here that it makes visual information available for use in the voluntary control of focal attention. To do so I use both introspection and neurophysiological evidence from projections between areas of attentional control and neural correlates of consciousness. Campbell and Smithies also identify roles for experience, but they further argue that only experience can play those roles. In contrast, I argue that (...) experience is not the only way in which visual information could be accessed for the voluntary control of attention. (shrink)

A long-standing theme in discussion of perception and thought has been that our primary cognitive contact with individual objects and events in the world derives from our perceptual contact with them. When I look at a duck in front of me, I am not merely presented with the fact that there is at least one duck in the area, rather I seem to be presented withthisthing (as one might put it from my perspective) in front of me, which looks to (...) me to be a duck. Furthermore, such a perception would seem to put me in a position not merely to make the existential judgment that there is some duck or other present, but rather to make a singular, demonstrative judgment, that that is a duck. My grounds for an existential judgment in this case derives from my apprehension of the demonstrative thought and not vice versa. (shrink)

In this paper we address the issue of grounding for experiential concepts. Given that perceptual demonstratives are a basic form of such concepts, we examine ways of fixing the referents of such demonstratives. To avoid ‘encodingism’, that is, relating representations to representations, we postulate that the process of reference fixing must be bottom-up and nonconceptual, so that it can break the circle of conceptual content and touch the world. For that purpose, an appropriate causal relation between representations and the world (...) is needed. We claim that this relation is provided by spatial and object-centered attention that leads to the formation of object files through the function of deictic acts. This entire causal process takes place at a pre-conceptual level, meeting the requirement for a solution to the grounding problem. Finally we claim that our account captures fundamental insights in Putnam’s and Kripke’s work on “new” reference. (shrink)

What is the philosophical significance of attention? The present article provides an overview of recent debates surrounding the connections between attention and other topics of philosophical interest. In particular, it discusses the interplay between attention and consciousness, attention and agency, and attention and reference. The article outlines the questions and contemporary positions concerning how attention shapes the phenomenal character of experience, whether it is necessary or sufficient for consciousness, and whether it plays a special role in the best philosophical theories (...) of action or conceptual reference. Various interdependencies between the answers to these questions are indicated, as well as how these answers might depend on the metaphysics of attention. Together with its companion piece this article serves as an introduction to the philosophy of attention. (shrink)

In this paper I address the question of whether bodily awareness is a form of perceptual awareness or not. I discuss José Luis Bermúdez’s and Shaun Gallagher’s proposals about this issue and find them unsatisfactory. Then I suggest an alternative view and offer some reasons for it.

1. Introduction In ‘The Refutation of Idealism’, G.E.Moore observed that, "when we try to introspect the sensation of blue, all we can see is the blue: the other element is as if it were diaphanous" (1922; p.25). Many philosophers, but Gilbert Harman (1990, 1996) in particular, have suggested that this observation forms the basis of an argument against qualia, usually called the argument from diaphanousness or transparency.1 But even its friends concede that it is none too clear what the argument (...) from diaphanousness—as I will call it—is (Tye 2000; p.45).2 The purpose of this paper is to formulate the argument, and to assess its merits. My conclusion will be that qualia realists have little to fear from the argument—provided both qualia and diaphanousness are properly understood. (shrink)

I argue for the view that some we-thoughts are immune to error through misidentification (IEM) relative to the first-person plural pronoun. To prepare the ground for this argument I defend an account of the semantics of ‘we’ and note the variety of different uses of that term. I go on to defend the IEM of a certain range of we-thoughts against a number of objections.

I examine John Campbell’s claim that the determination of the reference of a perceptual demonstrative requires conscious visual object-based selective attention. I argue that although Campbell’s claim to the effect that, first, a complex binding parameter is needed to establish the referent of a perceptual demonstrative, and, second, that this referent is determined independently of, and before, the application of sortals is correct, this binding parameter does not require object-based attention for its construction. If object-based attention were indeed required then (...) the determination of the referent would necessarily involve the application of sortal concepts, since object-based attention initiates top-down cognitive effects on visual processing. I also examine Mohan Matthen’s claim that reference to objects is established only through the visual processing in the dorsal visual stream and argue that although it is true that processing in the dorsal stream can determine reference, a thesis that goes against Campbell’s view that the determination of the referent requires conscious attention, processing along the ventral visual stream can also establish the reference of perceptual demonstratives. It also claim that Matthen’s account of dorsal processing underestimates the kind of information processed along the dorsal stream and this has some implications regarding perceptual demonstratives reference fixing.

The paper argues that the reference of perceptual demonstratives is fixed in a causal nondescriptive way through the nonconceptual content of perception. That content consists first in spatiotemporal information establishing the existence of a separate persistent object retrieved from a visual scene by the perceptual object segmentation processes that open an object-file for that object. Nonconceptual content also consists in other transducable information, that is, information that is retrieved directly in a bottom-up way from the scene (motion, shape, etc). The (...) nonconceptual content of the mental states induced when one uses a perceptual demonstrative constitutes the mode of presentation of the perceptual demonstrative that individuates but does not identify the object of perceptual awareness and allows reference to it. On that account, perceptual demonstratives put us in a de re relationship with objects in the world through the non-conceptual information retrieved directly from the objects in the environment.

ABSTRACTThe notion of immunity to error through misidentification has played a central role in discussions of first-person thought. It seems like a way of making precise the idea of thinking about oneself ‘as subject’. Asking whether bodily first-person judgments can be IEM is a way of asking whether one can think about oneself simultaneously as a subject and as a bodily thing. The majority view is that one cannot. I rebut that view, arguing that on all the notions of IEM (...) that have so far been successfully defined, bodily first-person judgments can be IEM. (shrink)

According to Paul Snowdon, one directly perceives an object x iff one is in a position to make a true demonstrative judgement of the form “That is x”. Whenever one perceives an object x indirectly (or dependently , as Snowdon puts it) it is the case that there exists an item y (which is not identical to x) such that one can count as demonstrating x only if one acknowledges that y bears a certain relation to x. In this paper (...) I argue that what we hear directly are sounds, and that material objects (such as violins and goldfinches) are only indirectly heard. However, there are cases of auditory object perception that should count as direct : Some blind persons’ ears are so sensitive to the way sound waves are modified by things in their surroundings that they can detect objects such as other persons, fences or trees. Interestingly, objects localized in this way make themselves felt via a kind of pressure in the perceiver’s face (that is why the phenomenon is commonly called “facial vision”), the perception is phenomenally quite different from hearing. Since, to some degree, most people are able to conclude from the way it sounds that, say, they stand at the foot of a concrete wall (when there is enough traffic noise around), we can imagine situations where two persons perceive the same wall, one indirectly (demonstratively apprehending sounds) and the other directly (demonstratively apprehending nothing but the wall). These cases invite us to discuss the role phenomenology plays in determining whether an object is perceived directly or indirectly. (shrink)

: I present an argument for the existence of nonconceptual representational content. The argument is compatible with McDowell's defence of conceptualism against those arguments for nonconceptual content that draw upon claims about the fine‐grainedness of experience. I present a case for nonconceptual content that concentrates on the idea that experience can possess representational content that cannot perform the function of conceptual content, namely figure in the subject's reasons for belief and action. This sort of argument for nonconceptual content is best (...) achieved with examples from auditory perception, especially our perception of music. (shrink)

John McDowell (in Mind and World) and Bill Brewer (in Perception and Reason) argue that the content of our perceptual experience is conceptual in the following sense. It is of the type of content that could be the content of a judgement – that is, a content which results from the actualization of two (or more) conceptual abilities. Specifically, they suggest that the conceptual abilities actualized in experience are demonstrative abilities, and thus the resulting content is of the type we (...) may express by means of sentences of the form ‘this is thus’. In this paper I argue that we cannot construe experiential contents in this way. I first outline a construal of the ability to think about a thing being thus which is based on Brewer's discussion of conceptual experiential contents, and which I take to be the best construal available to the conceptualist. I then show that on this construal the demonstrative abilities that account for our experience of properties require intentional focused attention to the relevant properties. The conceptualist is thus committed to holding that we experience only the properties we are intentionally attending to, and I argue that this is implausible. The interest in examining Brewer's conceptualist construal of experiential content and pointing out its shortcoming is not limited merely to an interest in whether there is a workable conceptualist account of experiential content. I suggest that certain aspects of Brewer's construal capture important (and often neglected) aspects of our perceptual experience, and that understanding why the account fails can contribute to our understanding of both experiential content and demonstrative thought.

The objective of this paper is to discuss the nature of nonconceptual, as opposed to conceptual, states and their content, by exploring the suggestion that the distinction between the conceptual and the nonconceptual be mapped onto the distinction between the linguistic and the nonlinguistic. This approach gives special relevance to our intuitions about the cognitive relationship between small children and adults, especially regarding the acquisition of concepts, in the course of normal cognitive development. Assuming that there is a developmental challenge (...) to be met, the paper considers both the conceptualist and nonconceptualist strategies used to meet it; and concludes that conceptualism is a more satisfying option.

I discuss an aspect of the relation between accounts of de se thought and the phenomenon of immunity to error through misidentification. I will argue that a deflationary account of the latter—the Simple Account, due to Evans —will not do; a more robust one based on an account of de se thoughts is required. I will then sketch such an alternative account, based on a more general view on singular thoughts, and show how it can deal with the problems I (...) raise for the Simple Account. (shrink)

We argue that recent empirical findings and theoretical models shed new light on the nature of attention. According to the resulting amplification view, attentional phenomena can be unified at the neural level as the consequence of the amplification of certain input signals of attention-independent perceptual computations. This way of identifying the core realizer of attention evades standard criticisms often raised against sub-personal accounts of attention. Moreover, this approach also reframes our thinking about the function of attention by shifting the focus (...) from the function of selection to the function of amplification. (shrink)

In crossmodal identification, a subject token identifies an item perceived in one sensory modality with an item perceived in another sensory modality. Does crossmodal identification always occur in cognition, or does crossmodal identification sometimes take place in perception? This paper argues that crossmodal identification occurs in cognition, and not in perception. Nevertheless, multisensory perception is not unalive to crossmodal identity. Experimental evidence demonstrates that perception is differentially sensitive to the identity of individuals presented to distinct senses. Such sensitivity enhances recognition (...) and improves action. This approach relies on distinguishing crossmodal identification from perceiving crossmodal identity. Perception registers crossmodal identity, but crossmodal identification as such belongs to thought. (shrink)

A longstanding philosophical tradition holds that the primary objects of hearing are sounds rather than sound sources. In this case, we hear sound sources by—or in virtue of—hearing their sounds. This paper argues that, on the contrary, we have good reason to believe that the primary objects of hearing are sound sources, and that the relationship between a sound and its source is much like the relationship between a color and its bearer. Just as we see objects in seeing their (...) colors, so we hear sound sources in hearing their sounds. (shrink)

Castañeda, Perry and Lewis argued in the 1960’s and 1970’s that thoughts about oneself “as oneself” – de se thoughts – require special treatment, and advanced different accounts. In this paper I discuss Ernest Sosa’s approach to these matters. I first present his approach to singular or de re thought in general in the first section. In the second, I introduce the data that need to be explained, Perry’s and Lewis’s proposals, and Sosa’s own account, in relation to Perry’s, Lewis’s, (...) and his own views on de re thought. In the third section I present the account I prefer – a “token-reflexive” version of Perry’s original account that Perry himself came to adopt in reaction to Stalnaker’s criticisms. In the final section I take up Recanati’s recent arguments, from a viewpoint on de se thought very similar to Sosa’s, to the effect that such an account is in a good position to explain the phenomenon of immunity to error through misidentification. I argue there that that is not the case, and I conclude by suggesting that the token-reflexive account fits better both with the data and with Sosa’s Fregean take on de re thought in general.

Saying ┌ that ψ is F ┐ when one should have said ┌ that φ is F ┐ involves making one of two different kinds of error. Either the wrong nominal term (┌ ψ ┐ instead of ┌ φ ┐) is ascribed to the right object or the right nominal term is ascribed to the wrong object. Judgments susceptible to one kind of error are immune to the other. Indexical terms such as ‘here’ and ‘now’ exhibit a corresponding pattern of (...) immunity and susceptibility to error, which suggests that they are complex demonstratives. This should also apply to ‘I’. (shrink)
