Everything is clear: All perceptual experiences are transparent

The idea that perceptual experience is transparent is generally used by naïve realists and externalist representationalists to promote an externalist account of the metaphysics of perceptual experience. It is claimed that the phenomenal character of our perceptual experience can be explained solely with reference to the externally located objects and properties which (for the representationalist) we represent, or which (for the naïve realist) partly constitute our experience. Internalist qualia theorists deny this and claim that the phenomenal character of our perceptual experience is internally constituted. However, my concern in this paper is not with the metaphysical debate but with transparency as a phenomenological feature of perceptual experience. Qualia theorists have presented a number of examples of perceptual experiences which, they claim, do not even seem to be transparent; these experiences involve objects or properties which seem to be internally realized. I argue, contrary to the qualia theorist's claim, that the phenomenal character of perceptual experience can in fact be characterized solely with reference to externally located objects and properties, and the sense in which some features of our perceptual experiences do not seem external is due to cognitive, not perceptual, phenomenology.     

Affect,perceptual experience,and disclosure

A prominent number of contemporary theories of emotional experience—understood as occurrent, phenomenally conscious episodes of emotions with an affective character that are evaluatively directed towards particular objects or states of affairs—are motivated by the claim that phenomenally conscious affective experience, when appropriate, grants us epistemic access not merely to features of the experience but also to features of the object of experience, namely its value. I call this the claim of affect as a disclosure of value. The aim of this paper is to clarify the sort of assumptions about experience that we ought to avoid if we want to be able to argue that for the claim of affect as a disclosure of value. There are two core arguments in this paper. First, I argue that Mark Johnston’s account of affect as a disclosure of value, due to its naïve realist commitments, relapses into a position that is vulnerable to the same objection put forward by some naïve realists against intentionalist accounts of perceptual experience. Second, I argue that Michelle Montague’s account, due to its phenomenal intentionalist commitments, relapses into a position that is vulnerable to the same objections put forward against qualia theories of the phenomenal character of perceptual experience. The upshot of the paper is that the core assumptions embedded in the three dominant models of experience—namely naïve realism, different versions of intentionalism, and qualia theory—are problematic as found in contemporary accounts of affect as a disclosure of value.     

Senses for senses

If two subjects have phenomenally identical experiences, there is an important sense in which the way the world appears to them is precisely the same. But how are we to understand this notion of ‘ways of appearing’? Most philosophers who have acknowledged the existence of phenomenal content have held that the way something appears is simply a matter of the properties something appears to have. On this view, the way something appears is simply the way something appears to be. This identification supports a Russellian theory of phenomenal content, according to which phenomenal content is exhausted by facts about what specific properties are represented by an experience. The present paper motivates and develops an alternative Fregean theory of phenomenal colour content. According to Fregean theories, the phenomenal content that is shared by any two phenomenally identical experiences is a matter of how the world is represented, and need not involve sameness in what is represented. It is argued that ways of appearing are modes of presentations of external properties and objects, and a detailed theory is presented about the nature of the modes of presentation involved in colour experience.     

Consciousness and topologically structured phenomenal spaces

There are strong reasons to believe that our conscious inner life is structured, suggested both by introspection as well as scientific psychology. One of the most salient structural characteristics of conscious experiences is known as unity of consciousness. In this contribution, we wish to demonstrate how features of experience that pertain to the unity of consciousness could be made precise in terms of mathematical relations that hold between phenomenal objects.Based on phenomenological considerations, we first outline three such features. These are (i) environmental embedding, (ii) the mutual constraint between local and global representations, and (iii) a top-down process of object formation in consciousness. We then introduce a formal model based on the notion of phenomenal space, defined in terms of a set of quasi-elementary and extended entities. We describe the structure of phenomenal space by appealing to mereological and topological concepts, and we outline a projector-based calculus to account for the idea that the structure of phenomenal space is ultimately dynamical.Using the above concepts, one could approach the mind-matter problem by relating environmentally embedded agents to topologically well-defined objects that result from decompositions of phenomenal space. We conclude our discussion by putting it into the context of some recent conceptual questions that appear in cognitive science and consciousness studies. We opt for the possibility to regard the phenomenon of consciousness not in terms of a singular transition that happens between “brain” and “mind” but rather in terms of a series of transitions between structured layers of experience.     

Towards a New Feeling Theory of Emotion

According to the old feeling theory of emotion, an emotion is just a feeling: a conscious experience with a characteristic phenomenal character. This theory is widely dismissed in contemporary discussions of emotion as hopelessly naïve. In particular, it is thought to suffer from two fatal drawbacks: its inability to account for the cognitive dimension of emotion (which is thought to go beyond the phenomenal dimension), and its inability to accommodate unconscious emotions (which, of course, lack any phenomenal character). In this paper, I argue that the old feeling theory is in reality only a pair of modifications removed from a highly plausible account of the nature of emotion that retains the essential connection between emotion and feeling. These modifications are, moreover, motivated by recent developments in work on phenomenal consciousness. The first development is the rising recognition of a phenomenal character proper to cognition—so‐called cognitive phenomenology. The second is the gathering momentum behind various ‘connection principles’ that specify some connection that a given state must bear to phenomenally conscious states in order to qualify as mental. These developments make it possible to formulate a new feeling theory of emotion, which would overcome the two fatal drawbacks of the old feeling theory. According to the new feeling theory, an emotion is a mental state that bears the right connection to conscious experiences with the right phenomenal character (involving, among other elements, a cognitive phenomenology).     

Cognitive Architecture, Concepts, and Introspection: An Information‐Theoretic Solution to the Problem of Phenomenal Consciousness

This essay is a sustained attempt to bring new light to some of the perennial problems in philosophy of mind surrounding phenomenal consciousness and introspection through developing an account of sensory and phenomenal concepts. Building on the information‐theoretic framework of Dretske (1981) , we present an informational psychosemantics as it applies to what we call sensory concepts, concepts that apply, roughly, to so‐called secondary qualities of objects. We show that these concepts have a special informational character and semantic structure that closely tie them to the brain states realizing conscious qualitative experiences. We then develop an account of introspection which exploits this special nature of sensory concepts. The result is a new class of concepts, which, following recent terminology, we call phenomenal concepts: these concepts refer to phenomenal experience itself and are the vehicles used in introspection. On our account, the connection between sensory and phenomenal concepts is very tight: it consists in different semantic uses of the same cognitive structures underlying the sensory concepts, such as the concept of red. Contrary to widespread opinion, we show that information theory contains all the resources to satisfy internalist intuitions about phenomenal consciousness, while not offending externalist ones. A consequence of this account is that it explains and predicts the so‐called conceivability arguments against physicalism on the basis of the special nature of sensory and phenomenal concepts. Thus we not only show why physicalism is not threatened by such arguments, but also demonstrate its strength in virtue of its ability to predict and explain away such arguments in a principled way. However, we take the main contribution of this work to be what it provides in addition to a response to those conceivability arguments, namely, a substantive account of the interface between sensory and conceptual systems and the mechanisms of introspection as based on the special nature of the information flow between them.     

Visual acquaintance,action and the explanatory gap

Much attention has recently been paid to the idea, which I label ‘External World Acquaintance’ (EWA), that the phenomenal character of perceptual experience is partially constituted by external features. One motivation for EWA which has received relatively little discussion is its alleged ability to help deal with the ‘Explanatory Gap’. I provide a reformulation of this general line of thought, which makes clearer how and when EWA could help to explain the specific phenomenal nature of visual experience. In particular, I argue that by focusing on the different kinds of perceptual actions that are available in the case of visual spatial vs. colour perception, we get a natural explanation for why we should expect the specific nature of colour phenomenology to remain less readily intelligible than the specific nature of visual spatial phenomenology.

     

Colour constancy and Fregean representationalism

All representationalists maintain that there is a necessary connection between an experience’s phenomenal character and intentional content; but there is a disagreement amongst representationalists regarding the nature of those intentional contents that are necessarily connected to phenomenal character. Russellian representationalists maintain that the relevant contents are composed of objects and/or properties, while Fregean representationalists maintain that the relevant contents are composed of modes of presentation of objects and properties. According to Fregean representationalists such as David Chalmers and Brad Thompson, the Fregean variety of the view is preferable to the Russellian variety because the former can accommodate purported counterexamples involving spectrum inversion without illusion and colour constancy while the latter cannot. I maintain that colour constancy poses a special problem for the Fregean theory in that the features of the theory that enable it handle spectrum inversion without illusion cannot be extended to handle colour constancy. I consider the two most plausible proposals regarding how the Fregean view might be developed in order to handle colour constancy—one of which has recently been defended by Thompson (Australas J Philos 87:99–117, 2009)—and argue that neither is adequate. I conclude that Fregean representationalism is no more able to accommodate colour constancy than is Russellian representationalism and, as such, ought to be rejected.     

Content externalism and phenomenal character: a new worry about privileged access

Some philosophers argue that the thesis of content externalism, according to which the contents of a subject’s thoughts are in part individuated by environmental factors, threatens the standard idea that a subject can know the contents of her thoughts without empirical investigation. It is typically assumed, however, that this thesis does not threaten another common idea about privileged access: that a subject can know the phenomenal character of her experience–its “what it’s like” aspect–without empirical investigation. That is, even if content externalism is true and does imply that a subject cannot know without empirical investigation the contents of some of her thoughts (e.g., her thoughts about water), surely she can know without empirical investigation what it’s like for her to be having whatever experience she is having. I argue that if content externalism threatens privileged access to content (I do not discuss whether it does), then it also threatens privileged access to phenomenal character. My argument does not involve claiming that phenomenal character is itself externally individuated. Rather, it depends on two other claims: (1) that introspective access to phenomenal character is conceptual; and (2) that standard arguments for content externalism suggest that some phenomenal concepts are externally individuated.     

Phenomenal Feel as Process1

Phenomenal character (or feel) is the what‐it's‐likeness of subjective experience. I develop an ontology of phenomenal feel as process. My being in some phenomenal state R is the process of my instantiating R’s neurological correlate. The ontology explains why we have asymmetric epistemic access to phenomenal characters: the ontological ground for the subjective or first‐personal stance is different from the ontological ground for the objective or third‐personal stance. I end by situating my account in debates about physicalism.     

The Goldilocks Problem of the specificity of visual phenomenal content

Existentialist accounts maintain that visual phenomenal content takes the logical form of an existentially quantified sentence. These accounts do not make phenomenal content specific enough. Singularist accounts posit a singular content in which the seen object is a constituent. These accounts make phenomenal content too specific. My account gets the specificity of visual phenomenal content just right. My account begins with John Searle's suggestion that visual experience represents an object as seen, moves this relation outside the scope of the existential quantifier and then replaces it with the relation of objects being ‘present as accessible’, as described by Alva Noë.     

The reticence of visual phenomenal character: A spatial interpretation of transparency

It is often claimed that the phenomenal character of visual experience is ‘transparent’ in that the phenomenal features of visual experience do not seem ‘mental’. It is then claimed that this transparency speaks in favour of some theories of experience while speaking against others. In this paper, I advance both a negative and a positive thesis about transparency. My negative thesis is that visual phenomenal character is reticent in that it does not reveal whether it is mental or non-mental in nature. This, in turn, means that, by itself, transparency does not speak in favour of (and against) the theories it is often thought to speak in favour of (and against). My positive thesis is that the phenomenon referred to as the ‘transparency’ of visual phenomenal character is best characterized in spatial, not mental, terms.     

Intentionalism and Change Blindness

According to reductive intentionalism, the phenomenal character of a conscious experience is constituted by the experience's intentional (or representational) content. In this article I attempt to show that a phenomenon in visual perception called change blindness poses a problem for this doctrine. Specifically, I argue that phenomenal character is not sensitive, as it should be if reductive intentionalism is correct, to fine-grained variations in content. The standard anti-intentionalist strategy is to adduce putative cases in which phenomenal character varies despite sameness of content. This paper explores an alternative antiintentionalist tack, arguing, by way of a specific example involving change blindness, that content can vary despite sameness of phenomenal character.

The intuitive case for naïve realism

Naïve realism, the view that perceptual experiences are irreducible relations between subjects and external objects, has intuitive appeal, but this intuitive appeal is sometimes thought to be undermined by the possibility of certain kinds of hallucinations. In this paper, I present the intuitive case for naïve realism, and explain why this intuitive case is not undermined by the possibility of such hallucinations. Specifically, I present the intuitive case for naïve realism as arguing that the only way to make sense of the phenomenal character associated with perceptual experiences is by means of a naïve realist ontology. I then explain why this intuitive argument is not undermined by the possibility of hallucinatory experiences that possess the phenomenal character associated with perceptual experiences but, being hallucinations, do not have the ontological nature specified by naïve realism.     

Affectively Driven Perception: Toward a Non-representational Phenomenology

While classical phenomenology, as represented by Edmund Husserl’s work, resists certain forms of representationalism about perception, I argue that in its theory of horizons, it posits representations in the sense of content-bearing vehicles. As part of a phenomenological theory, this means that on the Husserlian view such representations are part of the phenomenal character of perceptual experience. I believe that, although the intuitions supporting this idea are correct, it is a mistake to maintain that there are such representations defining the phenomenal character of low-level perception. What these representations are called on to explain, i.e., the phenomenal character of perceiving objects in their full presence, can be more parsimoniously explained by appealing to certain affective states or affect schemas that shape the intentional directedness of low-level perceptual experience and define its phenomenal character in a non-representational way. This revision of the Husserlian view, it is shown, also helps us understand the normative character of perception.     

Against Radical Enactivism’s narrowmindedness about phenomenality

Radical Enactivism rejects representationalism but nonetheless allows the phenomenal character of perceptual experience as supervening on brain bound elements. In this paper, I argue that Radical Enactivism should reject the possibility of wholly brain-bound phenomenal experience. I propose a way of individuating perceptual experiences that does not depend on representationalism and raises a problem to the view defended by Hutto and Myin (Radicalizing Enactivism: basic minds without content. MIT Press, Cambridge, 2012) according to which, with respect to phenomenality, it is possible to adopt a view that partly construes experience in terms of engagement with the environment. I argue that Radical Enactivism should change: either deny that the environment plays any role in an account of the phenomenal character or embrace the view that the phenomenal properties of experiences are at least partly constituted by the environment itself.

     

Phenomenal experience and the measure of information

This paper defends the hypothesis that phenomenal experiences may be very complex information states. This can explain some of our most perplexing anti-physicalist intuitions about phenomenal experience. The approach is to describe some basic facts about information in such a way as to make clear the essential oversight involved, by way illustrating how various intuitive arguments against physicalism (such as Frank Jackson’s Knowledge Argument, and Thomas Nagel’s Bat Argument) can be interpreted to show that phenomenal information is not different in kind from physical information, but rather is just more information than we typically attribute to our understanding of a physical theory. I clarify how this hypothesis is distinct from Nagel’s claim that the theory of consciousness may be inconceivable, and then in conclusion briefly describe how these results might suggest a positive and conservative physicalist account of phenomenal experience.     

Contingentism versus Necessitism: The Tractatus Standpoint

The paper provides an interpretation of section 2.013 of the Tractatus which casts light on the strategic role that that section plays in the early Wittgenstein’s version of the ontology of logical atomism. The far‐reaching consequences that the proposed interpretation has on the issue of the metaphysical nature of objects are spelled out, and the identification of Tractatus objects with phenomenal qualities, that is with phenomenal abstract universals, is shown to be fully consistent with those consequences. As a by‐product of the analysis, the standpoint of the Tractatus with respect to both contingentism and necessitism is clarified.     

Iterated Non‐Refutation: Robert Lockie on Relativism 1

Abstract

I argue that an experience’s sensuous elements play an ineliminable role in our being intentionally directed upon an entity through perception. More specifically, I argue that whenever we appreciate a sensuous element in experience, we appreciate an intrinsic and irreducibly phenomenal aspect of experience that I call phenomenal presence – an aspect of experience that I show is central to its presentational character – and that the appreciation of phenomenal presence is necessary for perceptual intentionality. If an experience is to possess intentionality, the experience itself must make an entity available as an object of perceptually-based singular beliefs and the experiencing subject, by virtue of undergoing the experience, must in some sense be able to appreciate that it has done so. Phenomenal presence is necessary for perceptual intentionality because it plays an ineliminable role in making an entity available to its subject in this way.     

Cognitive Architecture and the Epistemic Gap: Defending Physicalism without Phenomenal Concepts

The novel approach presented in this paper accounts for the occurrence of the epistemic gap and defends physicalism against anti-physicalist arguments without relying on so-called phenomenal concepts. Instead of concentrating on conceptual features, the focus is shifted to the special characteristics of experiences themselves. To this extent, the account provided is an alternative to the Phenomenal Concept Strategy. It is argued that certain sensory representations, as accessed by higher cognition, lack constituent structure. Unstructured representations could freely exchange their causal roles within a given system which entails their functional unanalysability. These features together with the encapsulated nature of low level complex processes giving rise to unstructured sensory representations readily explain those peculiarities of phenomenal consciousness which are usually taken to pose a serious problem for contemporary physicalism. I conclude that if those concepts which are related to the phenomenal character of conscious experience are special in any way, their characteristics are derivative of and can be accounted for in terms of the cognitive and representational features introduced in the present paper.
