The Nature of Perceptual Experience

In this paper, I discuss Noë’s enactive account of our perceptual encounter with the intrinsic properties of the surrounding objects. First, I argue that this view falls into a dilemma in which either we are left without a satisfactory explanation of this encounter or, in order to keep Noë’s view, we must abandon our ordinary intuitions about the ontological status of the intrinsic properties of objects. Then, I show that, strikingly, there is a suggestive unofficial strand running in Noë that (...) avoids this dilemma. Finally, I argue this unofficial thread leads to a view about the perspectival character of perceptual experience and the place of sensorimotor understanding in perceptual content that is to be preferred over Noë’s official view about these issues.

Väitetään, että nykypäivän populismi vetoaa tosiasioiden sijasta ”kokemukseen”. Mutta mitä on kokemus? Se ei ole vain ennakkoluuloihin nojautuvaa mutua eikä myöskään pelkkää empiirisen datan rekisteröintiä mutta liittyy molempiin. Artikkelin luoma tiivis katsaus kokemuksen käsitehistorian pääpiirteisiin osoittaa, että länsimaisen filosofian perinteessä kokemus on ymmärretty ohittamattomana vaiheena tiedon hankkimisessa ja koettelemisessa. Toisaalta kokemukseen on liitetty tiettyjä tiedollisia heikkouksia – kontingenssi, tilannesidonnaisuus ja ennakoimattomuus – jotka tieteellinen metodi on eri tavoin pyrkinyt voittamaan. Artikkeli esittää, että 1900-luvun filosofinen hermeneutiikka irrottautuu tästä perinteisestä kokemuksen välineellistämisestä (...) ja alistamisesta korkeammille päämäärille ja keskittyy uudella ja hedelmällisellä tavalla juuri mainittuihin kokemuksen ”vaaroihin”. Hermeneuttisesti ymmärretty kokemus muodostuu äärellisen ihmisen ainutkertaisista kohtaamisista todellisuuden muuttuvan ja ehtymättömän mielekkyyden kanssa – omalle ymmärrykselle vieraan toiseuden ja samalla oman ymmärryksen äärellisyyden ja inhimillisen äärellisyyden kohtaamisesta.

Context: The enactivist tradition, out of which neurophenomenology arose, rejects various internalisms – including the representationalist and information-processing metaphors – but remains wedded to one further internalism: the claim that the structure of perceptual experience is directly, constitutively linked only to internal, brain-based dynamics. Problem: I aim to reject this internalism and defend an alternative analysis. Method: The paper presents a direct-realist, externalist, sensorimotor account of perceptual experience. It uses the concept of counterfactual meaningful action to defend this view against (...) various objections. Results: This account of experience matches certain first-person features of experience better than an internalist account could. It is fully tractable as “normal science.” Implications: The neuroscientific conception of brain function should change from that of internal representation or modelling to that of enabling meaningful, embodied action in ways that constitutively involve the world. Neurophenomenology should aim to match the structure of first-person experience with the structure of meaningful agent-world interactions, not with that of brain dynamics. Constructivist content: The sensorimotor approach shows us what external objects are, such that we may enact them, and what experience is, such that it may present us with those enacted objects.

The aim for this thesis is to motivate, critically evaluate and defend the claim that subjects are able to consciously perceive the affordances of objects. I will present my protagonist, the ‘Conscious Affordance Theorist’, with what are two main obstacles to this claim. The first of these is that affordance perception correctly understood refers only to a kind of subpersonal visual processing, and not to a kind of conscious visual experience. I claim that this results in an explanatory gap at (...) the level of intentional action, which in order to correct we need to redefine the notion of affordance perception to include conscious as well as subpersonal affordance perception. Precisely, I claim that ‘affordance awareness’ has a crucial epistemological role to play, and that subjects must be able to consciously experience affordances in order to gain this awareness. In answer to this claim, I supplement the objection that affordance perception is defined as subpersonal perception to include the claim that any awareness subjects have of the affordances of objects they visually experience is due to them having thoughts about those affordances, and not visual experience of them. I then consider the Conscious Affordance Theorist’s response to this supplemented account. The second obstacle is the claim that conscious visual affordance perception is an impossible notion given that affordances are dispositional properties, and the dispositional properties of objects cannot be ‘seen’. In facing this objection I look to the supporting claims and motivations that lie behind it, in order to find a way for the Conscious Affordance Theorist to challenge its central claim that affordances cannot be seen. I end this thesis with an account of the Conscious Affordance Theorist’s own positive position, and a consideration of how his account has the ability to provide for conscious affordance perception in the case of non-human animals.

I present a new version of the adverbial theory of visual experience, and give a semantic argument for it.

My main aim is to clarify what we mean by ‘look’ sentences such as (1) below – ones that we use to talk about visual experience: -/- (1) The ball looked red to Sue -/- This is to help better understand a part of natural language that has so far resisted treatment, and also to help better understand the nature of visual experience. -/- By appealing to general linguistic principles I argue for the following account. First, we use (1) to (...) talk about an event. Second, we use the verb ‘look’ to specify the kind of event about which we are talking – it is a looking event. Third, we use the subject ‘the ball’ to specify a stimulus of the event – something that looks some way in the event. Fourth, we use the adjunct ‘to Sue’ to specify an experiencer of the event – someone to whom things look some way in the event. Finally, we use the complement ‘red’ to specify a way of the event – a way in which the event occurs (I take ways of occurring to be properties of events). Which way do we use ‘red’ in (1) to specify? I argue: the maximally specific way w such that the following is generically true: looking events whose stimulus is red occur in way w (it is important that this is understood generically: this is what does much of the work in explaining our use of (1) and other ‘look’ sentences). Putting this together, what we mean by (1) is: there was a looking event whose stimulus was the ball, whose experiencer was Sue, and which occurred in the maximally specific way that looking events occur when their stimulus is red. -/- This account of how we use ‘red’ in (1) is one of the most interesting aspects of my thesis. It extends to an account of how we use ‘proud’ in ‘John walks proud’, ‘as if he is American’ in ‘John talks as if he is American’, ‘like a duck’ in ‘John sounds like a duck’, and so on. In each case we use the expression in question to specify a way: the maximally specific way proud people walk, the maximally specific way American people talk, and so on. So the study of ‘look’ sentences has much to tell us about the functioning of many other English language constructions, and suggests that ways have a significant role to play in the semantics of natural language – a fact that has not yet been sufficiently recognised by linguists or philosophers of language. -/- My thesis also has implications for the philosophy of perception. One of the central questions about perception is: What is the nature of visual experience? What is it, for example, for a ball to look red to Sue? My thesis offers an answer: What it is for the ball to look red to Sue is for whatever it is that we mean by ‘The ball looks red to Sue’ to be the case, and what we mean by ‘The ball looks red to Sue’ is that there is a looking event whose stimulus is the ball, whose experiencer is Sue, and which is occurring in a certain way. It thus delivers an adverbial account of visual experience, one that has the resources to better deal with problems that are traditionally thought to be decisive against adverbial accounts. (shrink)

[written in 2002/2003 while I was a graduate student at the University of Connecticut and ultimately submitted as part of my qualifying exam for the Masters of Philosophy] The question I am interested in revolves around Kant’s notion of the unity of experience. My central claim will be that, apart from the unity of experiencings and the unity of individual substances, there is a third unity: the unity of Experience. I will argue that this third unity can be conceived of (...) as a sort of ‘experiential space’ with the Aesthetic and Categories as dimensions. I call this ‘Euclidean Experience’ to emphasize the idea that individual experiencings have a ‘location’ within this framework much like individual objects have a location in space and time. The first sort of unity, that of experiences (or ‘experiencings’ as I will call them) is not enough. In order to have self-consciousness (ascribed atomic experiencings) there must be a consciousness in which the experiencings ‘take place’ just as in order for there to be objects there must be space in which they are located. With such a notion of experience in hand I argue that it can be used to bring together the solipsistic and non-solipsistic strands in Kant’s thinking. The resulting position I call ‘Polysolipsism.’.

The philosophy of perception has been mostly focused on vision, to the detriment of other modalities like audition or olfaction. In this paper I focus on olfaction and olfactory experience, and raise the following questions: is olfaction a perceptual-representational modality? If so, what does it represent? My goal in the paper is, firstly, to provide an affirmative answer to the first question, and secondly, to argue that olfaction represents odors in the form of olfactory objects, to which olfactory qualities are (...) attributed. In order to do this I develop an empirically adequate notion of olfactory object that is sensitive to the peculiarities of olfaction, and defend it against various objections. (shrink)

In this paper I will discuss the intentionalist view of perception, and present some arguments to support the view that, contrary to Michael Martin’s criticism, intentionalists do not need to conceive the content of perception as either singular or general, because this is not the way that it should be thought. The right way to conceive the representational content of perception is by considering it as informational and functional.

Što je distinktivno filozofski problem opažanja? Ovdje se tvrdi da je to konflikt između prirode opažajnog iskustva kakva nam se intuitivno čini, te stanovitih mogućnosti koje su implicitne upravo u ideji iskustva: mogućnosti iluzije i halucinacije. Opažajno iskustvo čini nam se kao odnos prema svojim objektima, vrsta »otvorenosti prema svijetu« koja uključuje izravnu svijest postojećih objekata i njihovih svojstava. Ali ako netko može imati iskustvo iste vrste a da objekt nije tamo – halucinaciju objekta – onda izgleda da opažajno iskustvo (...) ne može esencijalno biti takav odnos. Ovo je fundamentalni filozofski problem opažanja; različite filozofijske teorije opažanja 20. i 21. stoljeća mogu se sagledati kao odgovori na to.What is the distinctively philosophical problem of perception? Here it is argued that it is the conflictbetween the nature of perceptual experience as it intuitively seems to us, and certain possibilitieswhich are implicit in the very idea of experience: possibilities of illusion and hallucination. Perceptualexperience seems to us to be a relation to its objects, a kind of “openness to the world” whichinvolves direct awareness of existing objects and their properties. But if one can have an experienceof the same kind without the object being there – a hallucination of an object – then it seems thatperceptual experience cannot essentially be such a relation. This is the fundamentally philosophicalproblem of perception; the various philosophical theories of perception in the 20th and 21st centuriescan be seen as responses to it. (shrink)

We can anticipate what is yet to happen, remember what has already happened, but our immediate experience is confined to the present, the here and now. So much seems common sense. So much so that it is no surprise to see Thomas Reid, that pre-eminent champion of common sense in philosophy, advocating precisely this position.

Raffaella De Rosa discusses the theory of sensory perception, especially color perception, offered by Ren Descartes. She offers a detailed overview of the recent literature on the topic and provides a new reading of Descartes' theory; she also raises questions of great interest in the contemporary philosophy of mind and cognitive science.

Seeing aspects is a dominant theme in Wittgenstein's 1940s writings on philosophy of psychology. Interpreters disagree about what Wittgenstein was trying to do in these discussions. I argue that interpreting Wittgenstein's observations about the interrelations between “noticing an aspect” and other psychological concepts as a systematic theory of aspect‐seeing diminishes key lessons of Wittgenstein's explorations: these interrelations are enormously complicated and “noticing an aspect” resists neat classification. Further, Wittgenstein invites us to engage in his “placing activity,” and by doing so (...) we are building a skill that is valuable for enabling us to help ourselves when we encounter conceptual difficulties.

Doxasticism about our awareness of normative (i.e. justifying) reasons – the view that we can recognise reasons for forming attitudes or performing actions only by means of normative judgements or beliefs – is incompatible with the following triad of claims: -/- (1) Being motivated (i.e. forming attitudes or performing actions for a motive) requires responding to and, hence, recognising a relevant reason. -/- (2) Infants are capable of being motivated. -/- (3) Infants are incapable of normative judgement or belief. -/- (...) It should be clear that (3) is true, given that infants lack the required reflective and conceptual capacities. So doxasticists have to reject either (1) or (2) (or both). But this forced choice may be understood as a dilemma for doxasticism. On the hand, doxasticists may adopt a Kantian approach and reject (2), precisely because they think that motivation presupposes the doxastic recognition of reasons, and because infants lack the capacity to doxastically recognise reasons. But this choice seems to wrongly reduce the responses of infants to mere reflexes or instinctive reactions. On the other hand, doxasticists may choose a Humean route and deny (1) by espousing a purely causal or teleological account of motivation. But this would mean detrimentally ignoring the normative nature of (some instances of) motivation. -/- One elegant way of avoiding this dilemma is to give up doxasticism and instead endorse experientialism – the view that we enjoy some experiential access to reasons, which is independent of, and perhaps more fundamental than, our capacity to form normative judgements and beliefs. In this talk, I would like to provide an argument for the existence of such a non-doxastic form of access to reasons. More specifically, I aim to defend the claim that our basic awareness of reasons is phenomenal in nature. What this means is that it forms part of our access from the inside to those of our mental episodes that provide us with access to reasons. In other words, when we introspectively attend to reason-giving mental episodes and what they are about, we have the impression of the presence of a reason for us. My defence of this experientialist alternative to doxasticism will primarily focus on perceptual reasons for first-order beliefs about the external world. (shrink)

Thomas Reid offers an explanation of how memory of events is possible. This paper presents, criticize,s and amends his view that memory not only preserves our knowledge of the external world, but also contributes to such knowledge, by being essential for the perception of events. Reid’s views on memory are in line with his generalanti-skeptical commitments, and thus attractive, for several reasons. One reason is that, just like perception, memory is not infallible, but it can constitute or, at least, ground (...) knowledge. Reid argues that memory, like perception, is immediate: it gives direct access to the external world, and not to mental representations of the external world. Another reason is that Reid’s explanation of how memory of events works emphasizes the impor- tance of the divide between memory and perception and consciousness: it is one thing to perceive or be conscious of something; it is another to remember that thing. Despite these advantages, a careful study of Reid’s views on memory will uncover a serious problem of general philosophical interest: it is unclear how exactly we are able to remember events episodically, since it is not settled whether we ever literally perceive events. This problem is engendered by a clash of the following two intuitions: (i) we can perceive only presently existing things, and (ii) we can remember events, which usually span periods of time longer than the present (whether the present is durationless or not).

Intermodal representationalism is a popular theory of consciousness. This paper argues that intermodal representationalism is false, or at least likely so. The argument turns on two forms of exceptional episodic memory: hyperthymesia and prodigious visual memory in savant syndrome. Emerging from this argument is a broader lesson about the relationship between memory and perception; that it may be possible to entertain in memory the very same content as in a corresponding perceptual experience, and that the ‘overflow’ interpretation of the classic (...) Sperling paradigm experiments may not fully generalize. (shrink)

Recently, several theorists have proposed that we can perceive a range of high-level features, including natural kind features (e.g., being a lemur), artifactual features (e.g., being a mandolin), and the emotional features of others (e.g., being surprised). I clarify the claim that we perceive high-level features and suggest one overlooked reason this claim matters: it would dramatically expand the range of actions perception-based theories of action might explain. I then describe the influential phenomenal contrast method of arguing for high-level perception (...) and discuss some of the objections that have been raised against this strategy. Finally, I describe two emerging defenses of high-level perception, one of which appeals to a certain class of perceptual deficits and one of which appeals to adaptation effects. I sketch a challenge for the latter approach. (shrink)
