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)

No particular dagger was the object of Macbeth’s hallucination of a dagger. In contrast, when he hallucinated his former comrade Banquo, Banquo himself was the object of the hallucination. Although philosophers have had much to say about the nature and philosophical import of hallucinations (e.g. Macpherson and Platchias, Hallucination, 2013) and object-involving attitudes (e.g. Jeshion, New essays on singular thought, 2010), their intersection has largely been neglected. Yet, object-involving hallucinations raise interesting questions about memory, perception, and the ways in which (...) we have knowledge of the world around us. In this paper, I offer an account of object-involving hallucinations. Specifically, I argue that they are an unusual species of perceptual remembering. (shrink)

This thesis articulates a novel interpretation of Heidegger’s explication of the being (Seins) of gear (Zeugs) in §15 of his masterwork Being and Time (1927/2006) and develops and applies the position attributed to Heidegger to explain three phenomena of unreflective action discussed in recent literature and articulate a partial Heideggerian ecological metaphysics. Since §15 of BT explicates the being of gear, Part 1 expounds Heidegger’s concept of the ‘being’ (Seins) of beings (Seienden) and two issues raised in the ‘preliminary methodological (...) remark’ in §15 of BT regarding explicating being. §1.1 interprets the being (Sein) or synonymously constitution of being (Seinsverfassung) of a being (Seienden) as a regional essence: a property unifying a region (Region), district (Bezirk), or subject-area (Sachgebiet) – a highly general (‘regional’) class of entities. Although Heidegger posits two components of the being of a being, viz. material-content (Sachhaltigkeit, Sachgehalt) and mode-of-being (Seinsart) or way-of-being (Seinsweise, Weise des Seins, Weise zu sein) (1927/1975, 321), the unclarity of this distinction means that it does not figure prominently herein. §1.2 addresses Heidegger’s distinction between ontological and ontic investigations and his notion of ‘modes of access’ (Zugangsarten, Zugangsweisen). Part 2 expounds §15 of BT’s explication of the being of gear. §2.1 analyses Heidegger’s two necessary and sufficient conditions for being gear and three core basic concepts (Grundbegriffe) enabling comprehension of these conditions and therewith a foundational comprehension of gear. Heidegger explicates the being of gear through content of unreflectively purposeful, non-intersubjective intentional states. I term such states ‘mundane concern’, which is almost synonymous with Hubert Dreyfus’s term ‘absorbed coping’ (1991, 69). Heidegger’s explication highlights around-for references (Um-zu-Verweisungen) as the peculiar species of property figuring in mundanely concernful intentional content. §2.2 clarifies Heidegger’s position on the relationship between to-hand-ness (Zuhandenheit) and extantness (Vorhandenheit) in the narrow sense: two of Heidegger’s most widely discussed concepts. I reject Kris McDaniel’s recent reading of Heidegger as affirming that nothing could be both to-hand and extant simultaneously (McDaniel 2012). Part 3 develops and applies Heidegger’s phenomenology of mundane concern. §3.1 explains the phenomena of situational holism, situated normativity, and mundanely concernful prospective control. §3.2 undertakes the metaphysical accommodation of around-for references, which §3.1 posited as featuring prominently within mundanely concernful intentional content. This thesis thus contributes not only to Heidegger scholarship, but also to contemporary debates within the philosophy of action and cognitive science. (shrink)

This thesis introduces the Problem of Consciousness as an antinomy between Physicalism and Primitivism about the phenomenal. I argue that Primitivism is implausible, but is supported by two conceptual gaps. The ‘–tivity gap’ holds that physical states are objective and phenomenal states are subjective, and that there is no entailment from the objective to the subjective. The ‘–trinsicality gap’ holds that physical properties are extrinsic and phenomenal qualities are intrinsic, and that there is no entailment from the extrinsic to the (...) intrinsic. Stoljar’s Epistemic View (EV) suggests that we have a limited conception of the physical world, and that the apparent inexplicability of consciousness is merely a symptom of our ignorance. I argue that EV must satisfy two conditions which require it to specify the content of our ignorance. EV’s best hope is a Russellian appeal to our ignorance of intrinsic physical properties. After arguing in favour of this ignorance claim, I show how it undermines the –trinsicality gap. However, I suggest that the –tivity gap cannot be dealt with by the Russellian ignorance hypothesis, nor by any other version of EV. However, I then argue that the Russellian ignorance hypothesis can still be deployed as half of a hybrid account of the phenomenal. Representationalist theories of consciousness have difficulty with the –trinsicality gap, but show promise with the –tivity gap. Specifically, Kriegel’s Self-Representationalism indicates that there can indeed be an entailment from objective physical states to subjective phenomenal states. This paves the way for my hybrid account of consciousness: the subjectivity of a phenomenal state is the product of its self-representational structure, and the qualitative character of a phenomenal state is the product of the epistemically inaccessible intrinsic physical properties involved in its implementation.

The central thesis (CT) that this paper upholds is that a picture depicts an object by generating in those who view the picture a visual experience of that object. I begin by presenting a brief sketch of intentionalism, the theory of perception in terms of which I propose to account for pictorial experience. I then discuss Richard Wollheim’s twofoldness thesis and explain why it should be rejected. Next, I show that the socalled unique phenomenology of pictorial experience is simply an (...) instance of perceptual indeterminacy. Lastly, I discuss a phenomenon associated with pictures that could be considered a problem for CT, and account for it by invoking the thesis that visual experience is cognitively penetrable.

When philosophers of perception contemplate concrete examples, the tendency is to choose perceptions whose content does not essentially involve time, but concern how things are at the moment they are perceived. This is true whether the cases are veridical (seeing a tree as a tree) or illusory (misperceiving the colour or spatial properties of an object). Less discussed, and arguably more complex and interesting cases do involve time as an essential element: perceiving movement, for example, or perceiving the order and (...) comparative duration of events. And, like other kinds of perception, time perception can involve illusions, such as the puzzling ‘stopped clock’ illusion. I want to suggest that these dynamic cases, and perhaps particularly those involving illusion, make a distinctive contribution to the direct realist/sense datum theory debate over perception, and they undermine a popular argument in favour of the objective passage of time, namely that passage is an ineliminable feature of our temporal experience.

Some philosophers deny the existence of composite material objects. Other philosophers hold that whenever there are some things, they compose something. The purpose of this paper is to scrutinize an objection to these revisionary views: the objection that nihilism and universalism are both unacceptably uncharitable because each of them implies that a great deal of what we ordinarily believe is false. Our main business is to show how nihilism and universalism can be defended against the objection. A secondary point is (...) that universalism is harder to defend than nihilism. (shrink)

According to the phenomenological argument for disjunctivism, the reasons why we should prefer the disjunctive theory over its rivals is that (1) the disjunctive theory conforms the most to our pretheoretical or natural convictions about perception (what Michael Martin calls naïve realism), and (2) we should commit ourselves to naïve realism because it conforms the most to the phenomenology of the perceptual experience of objects. In this paper, I try to explain why is the phenomenal argument exceptionally strong argument for (...) disjunctivism and at the same time against sense-datum and intentional theories. Furthermore, I try to show that the disjunctivist’s explanation of hallucination (which is allegedly the weak point of the theory) is as plausible as its rivals’. (shrink)

This paper discusses a counterexample to the thesis that visual experience is cognitively impenetrable. My central claim is that sometimes visual experience is influenced by the perceiver’s beliefs, rendering her experience’s representational content indeterminate. After discussing other examples of cognitive penetrability, I focus on a certain kind of visual experience— that is, an experience that occurs under radically nonstandard conditions—and show that it may have indeterminate content, particularly with respect to low-level properties such as colors and shapes. I then explain (...) how this indeterminacy depends on the perceiver’s beliefs or thoughts. Finally, I attempt to generalize the case and show how other sorts of visual experiences can also be penetrated by beliefs and, hence, be indeterminate. (shrink)

Abstract I argue that the two primary motivations in the literature for positing seemings as sui generis mental states are insufficient to motivate this view. Because of this, epistemological views which attempt to put seemings to work don’t go far enough. It would be better to do the same work by appealing to what makes seeming talk true rather than simply appealing to seeming talk.

Illusions are thought to make trouble for the intuition that perceptual experience is "open" to the world. Some have suggested, in response to the this trouble, that illusions differ from veridical experience in the degree to which their character is determined by their engagement with the world. An understanding of the psychology of perception reveals that this is not the case: veridical and falsidical perceptions engage the world in the same way and to the same extent. While some contemporary vision (...) scientists propose to draw the distinction between veridical experience and illusion in terms of the satisfaction or non-satisfaction of “hidden assumptions” deployed in the course of normal perceptual inference, I argue for a different approach. I contend that there are, in a sense, no illusions – illusions are as “open” as veridical experiences. Percepts lack the kinds of intentional content that would be needed for perceptual misrepresntation. My view gives a satisfying solution to a philosophical problem for disjunctivism about the good case/bad case distinction: with respect to illusions, every "bad case" of seeing an X can be equally well construed as a "good case" of seeing some Y (different from X). -/- .

I argue against one way of understanding the claim that how one’s visual experience “seems” provides support for the naïve-realist theory and weighs against sense-data theories . If my argument is correct, and we abandon this way of understanding how experience “seems”, we would lose one reason for favouring naïve-realism at the start of the dialectic of the traditional problem of perception. En route, I distinguish diff erent ways of understanding the transparency of experience, consider how to make sense of (...) rival theorists’ disagreement over the manifest nature of visual phenomenology and recount a story about Wittgenstein.

This article further explains and develops a recent, comprehensive semantic naturalization theory, namely the interactive indexing (II) theory as described in my 2008 Minds and Machines article Semantic Naturalization via Interactive Perceptual Causality (Vol. 18, pp. 527–546). Folk views postulate a concrete intentional relation between cognitive states and the worldly states they are about. The II theory eliminates any such concrete intentionality, replacing it with purely causal relations based on the interactive theory of perception. But intentionality is preserved via purely (...) abstract propositions about the world that index, or correlate with, appropriate cognitive states. Further reasons as to why intentionality must be abstract are provided, along with more details of an II-style account of representation, language use and propositional attitudes. All cognitive representation is explained in terms of classification or sorting dispositions indexed by appropriate propositions. The theory is also related to Fodor’s representational theory of mind, with some surprisingly close parallels being found in spite of the purely dispositional basis of the II theory. In particular, Fodor’s insistence that thinking about an item cannot be reduced to sorting dispositions is supported via a novel two-level account of cognition—upper level propositional attitudes involve significant intermediate processing of a broadly normative epistemic kind prior to the formation of sorting dispositions. To conclude, the weak intentional realism of the II theory—which makes intentional descriptions of the world dispensable—is related to Dennett’s ‘intentional stance’ view, and distinguished from strong (indispensable) intentional realist views. II-style dispositions are also defended. (shrink)

What are intuitions? According to doxastic views, they are doxastic attitudes or dispositions, such as judgments or inclinations to make judgments. According to perceptualist views, they are—like perceptual experiences—pre-doxastic experiences that—unlike perceptual experiences—represent abstract matters as being a certain way. In this paper I argue against doxasticism and in favor of perceptualism. I describe two features that militate against doxasticist views of perception itself: perception is belief-independent and perception is presentational. Then I argue that intuitions also have both features. The (...) upshot is that intuitions are importantly similar to perceptual experiences, and so should not be identified with doxastic attitudes or dispositions. I consider a popular argument from the introspective absence of sui generis intuition experiences in favor of doxasticism. I develop a conception of intuition experiences that helps to defuse this argument. (shrink)

A satisfactory solution to the problem of consciousness would take the form of a simple yet fully general model that specifies the precise conditions under which any given state of consciousness occurs. Science has uncovered numerous correlations between consciousness and neural activity, but it has not yet come anywhere close to this. We are still looking for the Newtonian laws of consciousness. -/- One of the main difficulties with consciousness is that we lack a language in which to formulate illuminating (...) generalizations about it. Philosophers and scientists talk about "what it’s like", sensations, feelings, and perceptual states such as seeing and hearing. This language does not allow a precise articulation of the internal structures of conscious states and their inter-relations. It is inadequate to capture relations of the kind we are looking for between conscious states and physical states. -/- In this thesis I refine and defend a theory of consciousness which promises to solve this regimentation problem: the representational theory of consciousness. I argue that the representational theory can solve the regimentation problem and smooth out other important obstacles to a fruitful study of consciousness. I also make a case for the theory independently of its payoffs, and I discuss the leading opposing theories at some length. (shrink)

In this paper we advocate the thesis that qualia are tropes (or qualitons), and not (universal) properties. The main advantage of the thesis is that we can accept both the Wittgensteinian and Sellarsian assault on the given and the claim that only subjective and private states can do justice to the qualitative character of experience. We hint that if we take qualia to be tropes, we dissolve the problem of inverted qualia. We develop an account of sensory concept acquisition that (...) takes the presence of qualia as an enabling condition for learning. We argue that qualia taken to be qualitons are part of our mechanism of sensory concept acquisition. (shrink)

Conceptualism is the thesis that, for any perceptual experience E, (i) E has a Fregean proposition as its content and (ii) a subject of E must possess a concept for each item represented by E. We advance a framework within which conceptualism may be defended against its most serious objections (e.g., Richard Heck's argument from nonveridical experience). The framework is of independent interest for the philosophy of mind and epistemology given its implications for debates regarding transparency, relationalism and representationalism, demonstrative (...) thought, phenomenal character, and the speckled hen objection to modest foundationalism.

Phenomenal character is determined by representational content, which both hallucinatory and veridical experiences can share. But in the case of veridical experience, unlike hallucination, the external objects of experience literally have the properties one is aware of in experience. The representationalist can accept the common factor assumption without having to introduce sensory intermediaries between the mind and the world, thus securing a form of direct realism.

A theory is disjunctive insofar as it distinguishes genuine from non-genuine cases of some phenomenon P on the grounds that no salient feature of cases of one type is common to cases of the other type. Genuine and non-genuine cases of P are, in this sense, fundamentally different. Those who advocate disjunctivist theories have (for the most part) been concerned with perception and perceptual knowledge. This entry outlines two such theories: the disjunctivist theory of experience (cf. Brewer, Hinton, Martin, Snowdon, (...) Travis) and the disjunctivist theory of appearances (McDowell). (shrink)

In this paper, we propose an account of metaphor identification on the basis of contextual coherence. In doing so, we build on previous work by Nicholas Asher and Alex Lascarides that appeals to rhetorical relations in order to explain discourse structure and the constraints on the interpretation of metaphor that follow from it. Applying this general idea to our problem, we will show that rhetorical relations are sometimes insufficient and sometimes inadequate for deciding whether a given utterance is a case (...) of metaphor. They are insufficient, since rhetorical relations fall short at times of providing a basis for disambiguating between literal and metaphorical interpretations. In such cases, contextual information other than previous discourse needs to enter the picture. To this effect, we bring the idea of external consistency into play. Beyond that, though, we will argue that rhetorical relations are sometimes inadequate to account for coherence, if conceived as relations among sentences only. The reason is that extra-linguistic elements of the situation in which the sentence is uttered may be crucial for getting at the preferred interpretation. To account for these cases, we allow rhetorical relations to connect both with previous discourse and with extra-linguistic situations. In our final refinement of the notion of contextual coherence, we forfeit any appeal to rhetorical relations in favour of Questions Under Discussion (QUD). We defend the view that this account does not only explain the same sort of cases. What is more, it solves the issue of metaphor identification in impoverished contexts. (shrink)

Recently, a number of philosophers have argued that property illusions—cases in which we perceive a property, but that property is not the property it seems to us to be in virtue of our perceptual experience—and veridical illusions—cases in which we veridically perceive an object’s properties, but our experience of some specific property is nonetheless unsuccessful or illusory—can occur. I defend the contrary view. First, I maintain that there are compelling reasons to conclude that property illusions and veridical illusions can’t occur; (...) and second, I maintain that the considerations supporting the possibility of such cases are uncompelling.

The question is whether Urmson's account depicts Austin's method needs a qualified answer. Roughly, the answer is that what it presents is not Austin's method because it is not the whole of Austin's method. Urmson confines his attention to aspects of the inner structure of the method and leaves out the question of its motivation and possible aims.

In his paper “Whatever next? Predictive brains, situated agents, and the future of cognitive science,” Andy Clark seminally proposed that the brain's job is to predict whatever information is coming “next” on the basis of prior inputs and experiences. Perception fundamentally subserves survival and self-preservation in biological agents, such as humans. Survival however crucially depends on rapid and accurate information processing of what is happening in the here and now. Hence, the term “next” in Clark's seminal formulation must include not (...) only the temporal dimension (i.e., what is perceivednow) but also the spatial dimension (i.e., what is perceivedhereor next-to-my-body). In this paper, we propose to focus on perceptual experiences that happen “next,” i.e., close-to-my-body. This is because perceptual processing of proximal sensory inputs has a key impact on the organism's survival. Specifically, we focus on tactile experiences mediated by the skin and what we will call the “extended skin” or “second skin,” that is, immediate objects/materials that envelop closely to our skin, namely, clothes. We propose that the skin and tactile experiences are not a mere border separating the self and world. Rather, they simultaneously and inherently distinguishandconnect the bodily self to its environment. Hence, these proximal and pervasive tactile experiences can be viewed as a “transparent bridge” intrinsically relating and facilitating exchanges between the self and the physical and social world. We conclude with potential implications of this observation for the case of Depersonalization Disorder, a condition that makes people feel estranged and detached from their self, body, and the world.

Touch seems to enjoy some epistemic advantage over the other senses when it comes to attest to the reality of external objects. The question is not whether only what appears in tactile experiences is real. It is that only whether appears in tactile experiences feels real to the subject. In this chapter we first clarify how exactly the rather vague idea of an epistemic advantage of touch over the other senses should be interpreted. We then defend a “muscular thesis”, to (...) the effect that only the experience of resistance to our motor efforts, as it arises in effortful touch, presents us with the independent existence of some causally empowered object. We finally consider whether this muscular thesis applies to the perception of our own body. (shrink)

Judgments of visual resemblance (‘A looks like B’), unlike other judgments of resemblance, are often induced directly by visual experience. What is the nature of this experience? We argue that the visual experience that prompts a subject looking at A to judge that A looks like B is a visual experience of B. After elucidating this thesis, we defend it, using the ‘phenomenal contrast’ method. Comparing our account to competing accounts, we show that the phenomenal contrast between a visual experience (...) that induces the judgment that A looks like B, and a visual experience that does not induce this judgment, is best explained by the fact that the former visually represents B, whereas the latter does not.

The paper presents a new philosophical theory of blurred vision according to which visual experiences have two types of content: exteroceptive content, characterizing external entities, and interoceptive content, characterizing the state of the visual system. In particular, it is claimed that blurriness-related phenomenology interoceptively presents acuity of vision in relation to eye focus. The proposed theory is consistent with the representationalist thesis that phenomenal character supervenes on representational content and with the strong transparency thesis formulated in terms of mind-independentness. Furthermore, (...) the interoceptive approach is free from controversial assumptions adopted by other philosophical theories of blurred experiences and is able to account for the epistemic and motivational role of visual blur, i.e. that blurred experiences provide a prima facie justification for beliefs regarding our vision and motivate actions directed toward our eyes.

[Significantly updated in Chapter 7 of Awareness and the Substructure of Knowledge] Many have found it plausible that knowledge is a constitutively normative state, i.e. a state that is grounded in the possession of reasons. Many have also found it plausible that certain cases of proprioceptive knowledge, memorial knowledge, and self-evident knowledge are cases of knowledge that are not grounded in the possession of reasons. I refer to these as cases of basic knowledge. The existence of basic knowledge forms a (...) primary objection to the idea that knowledge is a constitutively normative state. In what follows I offer a way through the apparent dilemma of having to choose between either basic knowledge or the normativity of knowledge. The solution involves homing in on a state of awareness (≈non-accidental true representation) that is distinct from knowledge and which in turn grounds the normativity of knowledge in a way that is fully consistent with the existence of basic knowledge. An upshot of this is that externalist theories of knowledge turn out to be fully compatible with the thesis that knowledgeable beliefs are always beliefs that are justified by the reasons one possesses.

How does the philosophical debate between naive realism and intentionalism relate to the psychological debate between ecological theories and constructivist theories? The participants in each debate take themselves to be doing something distinctive, but I show that characterizing the distinction is difficult: the theories in both debates use inference to the best explanation to draw contingent conclusions about the constitutive nature of perception. I argue that both debates concern the metaphysics of perception, and that philosophers of perception are wrong to (...) think that constructivist and ecological theories are engaged in a distinct and non-metaphysical task.

Representationalism (aka intentionalism) has been the most significant weapon in the late twentieth century defence of direct realism. However, although the representationalist objection to the Phenomenal Principle might provide an effective response to the arguments from illusion and hallucination, plausible representationalist theories of perception are, when fleshed-out, incompatible with metaphysical direct realism’s directness-claim. Indeed within cognitive science, direct perception is the avowedly-radical anti-representationalist heterodoxy. Drawing on both the philosophy and cognitive science, we develop a robust argument against representationalist direct realism (...) which does not rest on illusory cases or the notion of an object of immediate awareness. None of the representations so far posited, or in prospect, can supply the content required of a representation in a direct realist theory of veridical perception. (shrink)

Many contemporary theorists charge that naïve realists are incapable of accounting for illusions. Various sophisticated proposals have been ventured to meet this charge. Here, we take a different approach and dispute whether the naïve realist owes any distinctive account of illusion. To this end, we begin with a simple, naïve account of veridical perception. We then examine the case that this account cannot be extended to illusions. By reconstructing an explicit version of this argument, we show that it depends critically (...) on the contention that perceptual experience is diaphanous, or more minimally and precisely, that there can be no difference in phenomenal properties between two experiences without a difference in the scenes presented in those experiences. Finding no good reason to accept this claim, we develop and defend a simple, naïve account of both veridical perception and illusion, here dubbed Simple, Austere Naïve Realism. (shrink)

This paper trials new experimental methods for the analysis of natural language reasoning and the development of critical ordinary language philosophy in the wake of J.L. Austin. Philosophical arguments and thought experiments are strongly shaped by default pragmatic inferences, including stereotypical inferences. Austin suggested that contextually inappropriate stereotypical inferences are at the root of some philosophical paradoxes and problems, and that these can be resolved by exposing those verbal fallacies. This paper builds on recent efforts to empirically document inappropriate stereotypical (...) inferences that may drive philosophical arguments. We demonstrate that previously employed questionnaire-based output measures do not suffice to exclude relevant confounds. We then report an experiment that combines reading time measurements with plausibility ratings. The study seeks to provide evidence of inappropriate stereotypical inferences from appearance verbs that have been suggested to lie at the root of the influential ‘argument from illusion’. Our findings support a diagnostic reconstruction of this argument. They provide the missing component for proof of concept for an experimental implementation of critical ordinary language philosophy that is in line with the ambitions of current ‘evidential’ experimental philosophy.

Conscious experiences are characterized by mental qualities, such as those involved in seeing red, feeling pain, or smelling cinnamon. The standard framework for modeling mental qualities represents them via points in geometrical spaces, where distances between points inversely correspond to degrees of phenomenal similarity. This paper argues that the standard framework is structurally inadequate and develops a new framework that is more powerful and flexible. The core problem for the standard framework is that it cannot capture precision structure: for example, (...) consider the phenomenal contrast between seeing an object as crimson in foveal vision versus merely as red in peripheral vision. The solution I favor is to model mental qualities using regions, rather than points. I explain how this seemingly simple formal innovation not only provides a natural way of modeling precision, but also yields a variety of further theoretical fruits: it enables us to formulate novel hypotheses about the space and structures of mental qualities, formally differentiate two dimensions of phenomenal similarity, generate a quantitative model of the phenomenal sorites, and define a measure of discriminatory grain. A noteworthy consequence is that the structure of the mental qualities of conscious experiences is fundamentally different from the structure of the perceptible qualities of external objects.

This article reviews the enactive approach to perception, which defends the role of objects, the subject and the environment in the configuration of the phenomenal character of perception, that is, the qualitative dimension of experience. Initially the case of hallucination and its implications in the understanding of the phenomenal character of perception is retaken. Then, two positions within analytic philosophy of perception, representationalism and disjunctivism, are critically explored. Finally, enactivism is presented as a more promising alternative.

This paper explores the relationship between a prominent version of the relational view of memory and recent work on forms of unsuccessful remembering or memory errors. I argue that unsuccessful remembering poses an important challenge for the relational view. Unsuccessful remembering can be divided into two kinds: misremembering and confabulating. I discuss each of these cases in light of a recent relational account, according to which remembering is characterized by an experiential relation to past events, and I argue that experiential (...) relations do not adequately distinguish between remembering and unsuccessful remembering. This is because there are, on the one hand, cases of remembering that do not instantiate the relevant experiential relations, and, on the other hand, cases of confabulation and misremembering that do instantiate the relevant experiential relations. I conclude by suggesting that any successful relationalist attempt to explain remembering needs to come to grips with unsuccessful remembering. (shrink)

Theories of philosophy of perception are too simplifying. Direct realism and representationalism, for example, are philosophical theories of perception about the nature of the perceived object and its location. It is common sense to say that we directly perceive, through our senses, physical objects together with their properties. However, if perceptual experience is representational, it only appears that we directly perceive the represented physical objects. Despite psychological studies concerning the role of memory in perception, what these two philosophical theories do (...) not explicate are the continuity of the external describable object and the role of memory in perceiving the continuity, difference, break or ending. Using empirical evidence of particular cases and the hypothetico-deductive model, this research article analyses how one is able to perceive the continuity of same things. The early stages of perceptual process are not sufficient for the perception of continuity. Empirical evidence of memory disorders shows that persons with a memory disorder do not perceive the same thing or the familiar place they previously saw and now experience or remember what they are thinking about, even if the object, the place or the person has remained the same. I will argue that the perception of continuity requires memory. In fact, observation indicates how the memory runs at the same time, when the object is seen over time. This fact implies the memory system’s essential role for perceiving the continuity of the same things. (shrink)

The goal of this piece is to put some pressure on Brian O’Shaughnessy’s claim that perceptual experiences are necessarily mental processes. The author targets two motivations behind the development of that view. First, O’Shaughnessy resorts to pure conceptual analysis to argue that perceptual experiences are processes. The author argues that this line of reasoning is inconclusive. Secondly, he repeatedly invokes a thought experiment concerning the total freeze of a subject’s experiential life. Even if this case is coherent, however, it does (...) not show that perceptual experiences are processes. (shrink)

Direct neurological and especially imaging-driven investigations into the structures essential to naturally occurring cognitive systems in their development and operation have motivated broadening interest in the potential for artificial consciousness modeled on these systems. This first paper in a series of three begins with a brief review of Boltuc’s (2009) “brain-based” thesis on the prospect of artificial consciousness, focusing on his formulation of h-consciousness. We then explore some of the implications of brain research on the structure of consciousness, finding limitations (...) in biological approaches to the study of consciousness. Looking past these limitations, we introduce research in artificial consciousness designed to test for the emergence of consciousness, a phenomenon beyond the purview of the study of existing biological systems.

This thesis proposes a perspective on language and its development by starting from two approaches. The first is the ecological-enactive approach to cognition. In opposition to the widespread idea that cognition is information-processing in the brain, the ecological-enactive approach explains human cognition in relational terms, as skilful interactions with a sociomaterial environment shaped by practices. The second is the metalinguistic approach to language, which holds that reflexive or metalinguistic language use – talking about talking – is crucial for understanding language (...) and its development. In particular, I defend two theses: 1. A child’s initial communicative behaviour can be explained in terms of attentional actions: social actions that function by directing someone else’s attention. 2. In order for the child’s communicative behaviour to be sensitive to key properties of language, such as semantic content and normativity, she needs to learn metalinguistic skills. The development of this ecological-enactive perspective on language serves two functions. First, the ecological-enactive approach started by considering basic behaviour, such as locomotion and grasping. An approach in the cognitive sciences, however, should be able to account for the full gamut of human cognition. If the perspective developed in this thesis is viable, this is a contribution to extending the ecological-enactive approach to typically human forms of cognition. Second, this perspective throws new light on philosophical problems concerning language. In the different chapters, I deal with questions concerning the nature of linguistic knowledge, explanations of communicative behaviour, and the origins of semantic content and linguistic normativity.

This book gives an account of work that I have done over a period of decades that sets out to solve two fundamental problems of philosophy: the mind-body problem and the problem of induction. Remarkably, these revolutionary contributions to philosophy turn out to have dramatic implications for a wide range of issues outside philosophy itself, most notably for the capacity of humanity to resolve current grave global problems and make progress towards a better, wiser world. A key element of the (...) proposed solution to the first problem is that physics is about only a highly specialized aspect of all that there is – the causally efficacious aspect. Once this is understood, it ceases to be a mystery that natural science says nothing about the experiential aspect of reality, the colours we perceive, the inner experiences we are aware of. That natural science is silent about the experiential aspect of reality is no reason whatsoever to hold that the experiential does not objectively exist. A key element of the proposed solution to the second problem is that physics, in persistently accepting unified theories only, thereby makes a substantial metaphysical assumption about the universe: it is such that a unified pattern of physical law runs through all phenomena. We need a new conception, and kind, of physics that acknowledges, and actively seeks to improve, metaphysical presuppositions inherent in the methods of physics. The problematic aims and methods of physics need to be improved as physics proceeds. These are the ideas that have fruitful implications, I set out to show, for a wide range of issues: for philosophy itself, for physics, for natural science more generally, for the social sciences, for education, for the academic enterprise as a whole and, most important of all, for the capacity of humanity to learn how to solve the grave global problems that menace our future, and thus make progress to a better, wiser world. It is not just science that has problematic aims; in life too our aims, whether personal, social or institutional, are all too often profoundly problematic, and in urgent need of improvement. We need a new kind of academic enterprise which helps humanity put aims-and-methods improving meta-methods into practice in personal and social life, so that we may come to do better at achieving what is of value in life, and make progress towards a saner, wiser world. This body of work of mine has met with critical acclaim. Despite that, astonishingly, it has been ignored by mainstream philosophy. In the book I discuss the recent work of over 100 philosophers on the mind-body problem and the metaphysics of science, and show that my earlier, highly relevant work on these issues is universally ignored, the quality of subsequent work suffering as a result. My hope, in publishing this book, is that my fellow philosophers will come to appreciate the intellectual value of my proposed solutions to the mind-body problem and the problem of induction, and will, as a result, join with me in attempting to convince our fellow academics that we need to bring about an intellectual/institutional revolution in academic inquiry so that it takes up its proper task of helping humanity learn how to solve problems of living, including global problems, and make progress towards as good, as wise and enlightened a world as possible.

This book develops a novel generalization of possible world semantics, called ‘world line semantics’, which recognizes worlds and links between world-bound objects (world lines) as mutually independent aspects of modal semantics. Addressing a wide range of questions vital for contemporary debates in logic and philosophy of language and offering new tools for theoretical linguistics and knowledge representation, the book proposes a radically new paradigm in modal semantics. This framework is motivated philosophically, viewing a structure of world lines as a precondition (...) of modal talk. The author provides a uniform analysis of quantification over individuals (physical objects) and objects of thought (intentional objects). The semantic account of what it means to speak of intentional objects throws new light on accounts of intentionality and singular thought in the philosophy of mind and offers novel insights into the semantics of intensional transitive verbs.

This paper provides new tools for philosophical argument analysis and fresh empirical foundations for ‘critical’ ordinary language philosophy. Language comprehension routinely involves stereotypical inferences with contextual defeaters. J.L. Austin’s Sense and Sensibilia first mooted the idea that contextually inappropriate stereotypical inferences from verbal case-descriptions drive some philosophical paradoxes; these engender philosophical problems that can be resolved by exposing the underlying fallacies. We build on psycholinguistic research on salience effects to explain when and why even perfectly competent speakers cannot help making (...) stereotypical inferences which are contextually inappropriate. We analyse a classical paradox about perception, suggest it relies on contextually inappropriate stereotypical inferences from appearance-verbs, and show that the conditions we identified as leading to contextually inappropriate stereotypical inferences are met in formulations of the paradox. Three experiments use a forced-choice plausibility-ranking task to document the predicted inappropriate inferences, in English, German, and Japanese. The cross-linguistic study allows us to assess the wider relevance of the proposed analysis. Our findings open up new perspectives for ‘evidential’ experimental philosophy. (shrink)

Clinical use of the term “confabulation” began as a reference to false memories in dementia patients. The term has remained in circulation since, which belies shifts in its definition and scope over time. “Confabulation” now describes a range of disorders, deficits, and anomalous behaviors. The increasingly wide and varied use of this term has prompted many to ask: what is confabulation? In recent years, many have offered answers to this question. As a general rule, recent accounts are accounts of broad (...) confabulation: attempts to unify the seemingly disparate features of all or most confabulatory phenomena under a shared set of characteristics or mechanisms. In this paper, I approach the question differently. I focus on a particular form of confabulation—mnemonic confabulation—so as to understand its distinctive features and the ways in which it does fit into accounts of broad confabulation. Understanding mnemonic confabulation is a project in the philosophy of memory; it plays an important role in guiding theories of remembering, as a form of error that must be distinguished from genuine remembering. Mnemonic confabulation, as I define it in Sect. 2, occurs when there is no relation between a person’s seeming to remember a particular event or experience and any event or experience from their past—either because there is no such event in their past or because any similarity to such an event is entirely coincidental. This account draws on my own theory of remembering, but shares many important points of consensus with other accounts of mnemonic confabulation, which I highlight in Sect. 3. In Sect. 4, I turn to accounts of broad confabulation—identifying three features such accounts have in common—and, for each, I argue that mnemonic confabulation lacks the requisite feature. As an error, mnemonic confabulation has more in common with perceptual hallucination than with the confabulatory phenomena included in standard accounts of broad confabulation. Recognizing that, despite the shared use of the term “confabulation” mnemonic confabulation and broad forms of confabulation are unrelated, is important for continued progress in debates about each.

This paper surveys selected (though arguably representative) versions of metaphysical and epistemological disjunctivism. Although they share a common logical structure, it is hard to find a further common denominator among them. Two main conclusions are: (1) a specific standpoint on the nature of perceptual relation is not such a common denominator, which means that it is very unlikely that all of these views could be refuted with a single objection; (2) contrary to what its name suggests, disjunctivism can be correctly (...) expressed without the employment of disjunction.

In this paper, I present the enactive theory of color that implies a form of color relationism. I argue that this view constitutes a better alternative to color subjectivism and color objectivism. I liken the enactive view to Husserl’s phenomenology of perception, arguing that both deconstruct the clear duality of subject and object, which is at the basis of the other theories of color, in order to claim the co-constitution of subject and object in the process of experience. I also (...) extend the enactive and phenomenological account of color to the more general topic of the epistemological and ontological status of sensory qualities (qualia), outlining the fields of enactive phenomenology and enactive ontology.

Este artigo propõe uma releitura do artigo Other Minds de J. L. Austin, um exemplo clássico e central do realismo de Oxford, que é hoje exponenciado por autores tão distintos entre si como John McDowell, Timothy Williamson, M. G. F. Martin, Paul Snowdon ou Charles Travis. Um objectivo da leitura é pôr em relevo algumas características da abordagem das questões epistemológicas no seio dessa corrente. Começo por contextualizar o estatuto da investigação epistemológica num quadro de filosofia da linguagem comum. Segue-se (...) uma análise do artigo Other Minds em cinco passos. Finalmente exploro a aplicação ao problema das outras mentes das considerações performativas sobre conhecimento desenvolvidas ao longo do artigo, focando em particular o caso do testemunho. (shrink)

This dissertation concerns the location and nature of phenomenal qualities. Arguably, these qualities naively seem to belong to perceived external objects. However, we also seem to experience phenomenal qualities in hallucinations, and in hallucinations we do not perceive any external objects. I present and argue for a theory of the phenomenal qualities, "brain theory", which claims that all phenomenal qualities we experience are physical properties instantiated in the brain, regardless of whether they are experienced in veridical perceptions or in hallucinations. (...) I begin by more carefully identifying the phenomenal qualities, discussing how they are related to "qualia" and "phenomenal character". Then I present brain theory, and investigate its implications for the perceptual relations we stand in to external objects, noting that it is mostly neutral. I also compare brain theory to a similar theory of perception advocated by Bertrand Russell. Next, I provide an overview over the competing theories of phenomenal qualities, and relate them to theories of perception, such as representationalism, qualia theory, sense data theory and disjunctivism. The majority of my argumentation for brain theory focuses on arguing that the phenomenal qualities are instantiated in the brain, rather than on arguing that they are physical properties. Instead, I largely assume physicalism. However, even independently of the physicalism assumption, I show that we have reason to believe that phenomenal qualities are experienced in hallucinations, and that qualities experienced in hallucinations are instantiated in internal objects, such as our brains or sense data. In the first step towards this conclusion I argue that theories which deny that phenomenal qualities are experienced in hallucinations face serious problems. In the next step I argue that theories which deny that phenomenal qualities experienced in hallucinations are instantiated in internal objects face serious problems. Finally, an important part of the argumentation is my replies to objections against brain theory, including common sense objections and the "observation objection". From these conclusions, together with the physicalism assumption, I infer that we have reason to believe that brain theory is true about hallucinations. On this basis, I then argue, through a generalizing argument, that the same is the case for veridical perceptions. (shrink)
