An epistemic argument for liberalism about perceptual content

This paper concerns the question of which properties figure in the contents of perceptual experience. According to conservatives, only low-level properties figure in the contents of perceptual experience. Liberals, on the other hand, claim that high-level properties, such as natural kind properties, artifacts, and even moral properties, can figure in the contents of perceptual experience. I defend a novel argument in favor of liberalism, the Epistemic Argument, which hinges on two crucial claims. The first is that many perceptual experiences of even neurotypical human beings can justify beliefs in high-level properties without providing justification for their low-level constituents. The second claim, roughly, is that any experience that alone provides (defeasible) justification for beliefs about some property p, other things being equal, has p as part of its content. In short, certain perceptual experiences represent high-level but not low-level properties, which entails that liberalism is true.     

Bodily awareness and novel multisensory features

According to the decomposition thesis, perceptual experiences resolve without remainder into their different modality-specific components. Contrary to this view, I argue that certain cases of multisensory integration give rise to experiences representing features of a novel type. Through the coordinated use of bodily awareness—understood here as encompassing both proprioception and kinaesthesis—and the exteroceptive sensory modalities, one becomes perceptually responsive to spatial features whose instances couldn’t be represented by any of the contributing modalities functioning in isolation. I develop an argument for this conclusion focusing on two cases: 3D shape perception in haptic touch and experiencing an object’s egocentric location in crossmodally accessible, environmental space.

     

Foundational beliefs and the structure of justification

I argue that our justification for beliefs about the external physical world need not be constituted by any justified beliefs about perceptual experiences. In this way our justification for beliefs about the physical world may be nondoxastic and this differentiates my proposal from traditional foundationalist theories such as those defended by Laurence BonJour, Richard Fumerton, and Timothy McGrew. On the other hand, it differs from certain non-traditional foundationalist theories such as that defended by James Pryor according to which perceptual experience is sufficient to justify beliefs about the external world. I propose that justification for propositions describing our perceptual experiences partially constitutes any justification we may possess for beliefs concerning the external world. In this way, our justification for beliefs about the physical world may only be inferential since it is grounded in any justification we have for at least one other proposition. This theory occupies an intermediate position between the two aforementioned foundationalist accounts, which allows it to sidestep problems that confront each of them.     

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.     

Representation,Presentation and the Epistemic Role of Perceptual Experience

Abstract

In this paper I argue that the representational theory of perception, on which the world is represented as being a certain way in perceptual experience, cannot explain how there can be a genuinely epistemic connection between experience and belief. I try to show that we are positively required to deny that perceptual consciousness is contentful if we want to make its fitness for epistemic duties intelligible. (So versions of the representational theory on which experience has a merely causal purchase on belief are not considered.) But my aim is not just negative. I try to defeat representationalism in such a way as to motivate a robustly presentational theory of perception. According to such a theory, perceptions are relations not between a subject and a content but between a subject and an ordinary object (such that if the relation holds at t, an appropriate subject and object must exist at t, and the object must be presented to the subject). I end by sketching an account of perceptual experience that is meant to show that, contrary to a very popular misconception, there is a way to conceive perceptual consciousness as relational and presentational (not intentional and representational) that does not succumb to the celebrated ‘myth of the Given’.     

The particularity and phenomenology of perceptual experience

I argue that any account of perceptual experience should satisfy the following two desiderata. First, it should account for the particularity of perceptual experience, that is, it should account for the mind-independent object of an experience making a difference to individuating the experience. Second, it should explain the possibility that perceptual relations to distinct environments could yield subjectively indistinguishable experiences. Relational views of perceptual experience can easily satisfy the first but not the second desideratum. Representational views can easily satisfy the second but not the first desideratum. I argue that to satisfy both desiderata perceptual experience is best conceived of as fundamentally both relational and representational. I develop a view of perceptual experience that synthesizes the virtues of relationalism and representationalism, by arguing that perceptual content is constituted by potentially gappy de re modes of presentation.     

‘The Echo of a Thought in Sight’: Property Perception,Universals and Wittgenstein

Contemporary philosophers of perception, even those with otherwise widely differing beliefs, often hold that universals enter into the content of perceptual experience. This doctrine can even be seen as a trivial inference from the observation that we observe properties – ways that things are – as well as things. I argue that the inference is not trivial but can and should be resisted. Ordinary property perception does not involve awareness of universals. But there are visual (and aural) experiences which do involve determinate universals: following Wittgenstein, I call these ‘aspect experiences’. The common view of perceptual content effectively conflates aspect experiences with mere property perceptions. Wittgenstein’s later writings on the philosophy of psychology provide an alternative way to think about both aspects and properties. It also forms a contrast with Wittgenstein’s own early treatment of perception in the Tractatus, the doctrine of which is much closer to the contemporary norm among philosophers of perception. In seeing how Wittgenstein moved away from his early view, we can see how we might move away from that norm.     

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.

     

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.     

Editorial Notice

Abstract

John McDowell has claimed that the rational link between perceptions and empirical judgements allows us to perceive objects as belonging to a wider reality, one which extends beyond the objects perceived. In this way, we can be said to have a perceptual awareness of the world. I argue that McDowell's account of this perceptual awareness does not succeed. His account as it stands does not have the resources to explain how our perceptions can present objects as belonging to a wider reality, regardless of the judgements we make about that reality. I suggest that we can give a better account of this perceptual awareness of the world by appealing to transcendental phenomenology. A phenomenological study of perceptual experiences describes how they are structured by a sense of the perceived objects as belonging to a world containing other objects of possible perception. I shall outline this sense we have of the world, and argue that it allows us to perceive objects as belonging to a wider reality. Transcendental phenomenology can thus help to explain our perceptual awareness of the world.     

Learning and the Development of Meaning: Husserl and Merleau‐Ponty on the Temporality of Perception and Habit

In this paper, I argue that the temporal openness of perceptual experience provides insight into the basic structure of learning. I draw on Husserl's account of the mutability of the retained past in Analyses Concerning Passive and Active Synthesis, and Merleau‐Ponty's account of the perceptual field, as well as his remarks on habit, in Phenomenology of Perception, in order to elucidate the relation between the perceptual past and the future it portends. More specifically, I argue that retention and habituation in perceptual experience open dimensions of meaning that transform the initial, initiating, experiences in which meaning is first established. As a result, our experience of meaning is always subject to further development that we cannot anticipate. This temporal openness has consequences for our learning to navigate a perceptual field, but also, I argue, for our developing more complex ways of engaging with the world. Specifically, I show how learning requires that we commit ourselves to an object or task before we are in a position to recognize the implications or significance of our commitment. I further consider the role that others play in the inherent openness of learning to the development of new meaning.     

Frege's Puzzle for Perception

According to an influential variety of the representational view of perceptual experience—the singular content view—the contents of perceptual experiences include singular propositions partly composed of the particular physical object(s) a given experience is about or of. The singular content view faces well‐known difficulties accommodating hallucinations; I maintain that there is also an analogue of Frege's puzzle that poses a significant problem for this view. In fact, I believe that this puzzle presents difficulties for the theory that are unique to perception in that strategies that have been developed to respond to Frege's puzzle in the case of belief cannot be employed successfully in the case of perception. Ultimately, I maintain that this perceptual analogue of Frege's puzzle provides a compelling reason to reject the singular content view of perceptual experience.     

Hornsby and Baker on the physicalist orthodoxy

I examine some recent claims put forward by L. A. Paul, Barry Dainton and Simon Prosser, to the effect that perceptual experiences of movement and change involve an (apparent) experience of ‘passage’, in the sense at issue in debates about the metaphysics of time. Paul, Dainton and Prosser all argue that this supposed feature of perceptual experience – call it a phenomenology of passage – is illusory, thereby defending the view that there is no such a thing as passage, conceived of as a feature of mind-independent reality. I suggest that in fact there is no such phenomenology of passage in the first place. There is, however, a specific structural aspect of the phenomenology of perceptual experiences of movement and change that can explain how one might mistakenly come to the belief that such experiences do involve a phenomenology of passage.     

Concepts,Attention, and Perception

Abstract

According to the conceptualist view in the philosophy of perception, we must possess concepts for all the objects, properties and relations which feature in our perceptual experiences. In this paper, I investigate the possibility of developing an argument against the conceptualist view by appealing to the notion of attention.

In Part One, I begin by setting out an apparently promising version of such an argument, a version which appeals to a link between attention and perceptual demonstrative concept possession. In Part Two, however, I show how the conceptualist can challenge what appears to be the key premise of the argument, and I go on to describe, in Part Three, an important further difficulty which we face if we attempt to overcome this challenge in a particular way. My conclusion will be that the conceptualist's challenge to the argument is convincing and hence that the argument remains inconclusive.     

Evans on Bodily Awareness and Perceptual Self‐Location

In Chapter 7 of The Varieties of Reference Evans implicitly outlines a view to the effect that bodily awareness plays no role in perceptual self‐location or in the specification of our perceptual perspective of the world. In this paper I discuss this story and offer an alternative proposal. Then I explore some consequences of this account for our understanding of the elusiveness of the self in perceptual experience.     

State Versus Content: The Unfair Trial of Perceptual Nonconceptualism

It has recently been pointed out that perceptual nonconceptualism admits of two different and logically independent interpretations. On the first (content) view, perceptual nonconceptualism is a thesis about the kind of content perceptual experiences have. On the second (state) view, perceptual nonconceptualism is a thesis about the relation that holds between a subject undergoing a perceptual experience and its content. For the state nonconceptualist, it thus seems consistent to hold that both perceptual experiences and beliefs share the same (conceptual) content, but that for a subject to undergo a perceptual experience, the subject need not possess the concepts involved in a correct characterization of such content. I argue that the consistency of this position requires a non-Fregean notion of content that fails to capture the way the subject grasps the world as being. Hence state nonconceptualism leaves perceptual content attribution unsupported. Yet, on a characterization of content along the relevant (neo-Fregean) lines, this position would become incoherent, as it would entail that a subject could exercise cognitive abilities she doesn’t possess. I conclude that, given the notion of content demanded by the debate, the state view does entail the content view after all.

Two Versions of the Conceptual Content of Experience

ABSTRACT

In ‘Avoiding the Myth of the Given’, McDowell revisits the main themes of Mind and World in order to make two important corrections: first, he does not longer believe that the content of perceptual experience is propositional in character; second, he does not believe now that the content of an experience needs to include everything the experience enables us to know non-inferentially. In this article, I take issue with both retractions. My thesis is that McDowell’s first version of perceptual content is preferable to the latest one.     

What Do We See When We See Total Darkness?

Seeing total darkness is a peculiar perceptual state: in it, the subject is visually aware of something while seeming to fail to be aware of anything. Recent treatments of the topic (Sorensen 2008 , Soteriou 2000 ) leave this particular puzzle unsolved. Here, I attempt a solution. Following Dretske, I begin by suggesting that the perceptual report ‘S sees (total) darkness’ is ambiguous between two distinct kinds of perceptual states: epistemic and non‐epistemic. This will lead to an examination of the metaphysics of what is supposed to be seen. I show, on the one hand, the difficulty of reducing the perception of total darkness to the perception of a particular instantiation of a property, and on the other, that it has important similarities with the perception of (non‐particular) ‘stuff’. I propose, finally, that the solution to the puzzle might involve postulating a novel ontological status for total darkness: that of a ‘concrete universal’. Potential implications of interest for particularism and for naïve realism are suggested.     

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.
