Two questions are addressed in this paper. First, what is it to see? I argue that it is veridical experience of things outside the perceiver brought about by looking. Second, what is it to see a material object? I argue that it is experience of an occupant of a spatial region that is a logical subject for other visual features, able to move to another spatial region, to change intrinsically, and to interact with other material objects. I show how this (...) theory is different from the idea that object-seeing is merely the visual segregation of a region of the visual field. Finally, I argue that we do not object-see objects reflected in mirrors, surfaces of back-lit objects, and depictions of objects. (shrink)

Listening to someone from some distance in a crowded room you may experience the following phenomenon: when looking at them speak, you may both hear and see where the source of the sounds is; but when your eyes are turned elsewhere, you may no longer be able to detect exactly where the voice must be coming from. With your eyes again fixed on the speaker, and the movement of her lips a clear sense of the source of the sound will (...) return. This ‘ventriloquist’ effect reflects the ways in which visual cognition can dominate auditory perception. And this phenomenological observation is one what you can verify or disconfirm in your own case just by the slightest reflection on what it is like for you to listen to someone with or without visual contact with them.

Do we directly perceive physical objects? What is the significance of the qualification ‘directly’ here? Austin famously denied that there was a unique interpretation by which we could make sense of the traditional debate in the philosophy of perception. I look here at Thompson Clarke’s discussion of G. E. Moore and surface perception to answer Austin’s scepticism.

Although meritorious, Naïve Realism faces theoretical issues stemming from the lack of clarity in the concepts forming its propositions and the relevant (but not usually acknowledged) diversity of its theses. In this paper, my goal is to provide a groundwork that mitigates these theoretical complications. One such distinction concerns its subject matter, in particular, whether it deals with the nature of perceptual episodes or their phenomenology. My first goal is to acknowledge such distinctions by delimiting the former option, which I (...) refer to as “Ontological Naïve Realism”. To accomplish this, I proposed a distinctively minimal version of this position. However, a thorough characterization of the acquaintance relation was necessary for its postulation, which revealed a diversity of the corresponding relations/predicates. This informed the postulation of the minimal thesis and thus the definition of Ontological Naïve Realism. Based on this definition, I also proposed a novel classification and taxonomy of the relevant forms of Ontological Naïve Realism, based on the width of the attribution of naïve-realistic features and whether or not they identify perceptions/illusions to acquaintance instantiations.

The Gestalt principle of isomorphism reveals the primacy of subjective experience as a valid source of evidence for the information encoded neurophysiologically. This theory invalidates the abstractionist view that the neurophysiological representation can be of lower dimensionality than the percept to which it gives rise.

Gilbert Ryle’s distinction between knowledge-how and knowledge-that emerged from his criticism of the “intellectualist legend” that to do something intelligently is “to do a bit of theory and then to do a bit of practice,” and became a philosophical commonplace in the second half of the last century. In this century Jason Stanley has attacked Ryle’s distinction, arguing that “knowing-how is a species of knowing-that,” and accusing Ryle of setting up a straw man in his critique of “intellectualism.” Examining the (...) use of the terms “intellectualism” and “anti-intellectualism” in the first half of the 20th century, in a wide-ranging debate in the social sciences as well as in philosophy, I show that Ryle was not criticizing a straw man, but a live historical position. In the context of this controversy, Ryle’s position represents a third way between “intellectualism” and “anti-intellectualism,” an option that has largely gone missing in the 21st century discussion. This argument illustrates how history can inform the history of philosophy, and how the history of philosophy can inform contemporary philosophical inquiry. (shrink)

Shoemaker argues that one could not hold both that the qualitative character of colour experience is inherited from the qualitative character of the experienced colour and that there are faultless forms of variation in colour perception. In this paper, I explain what is meant by inheritance and discuss in detail the problematic cases of perceptual variation. In so doing I argue that these claims are in fact consistent, and that the appearance to the contrary is due to an optional and (...) controversial conception of experience that should be rejected.

Colors are sensible qualities. They are qualities that objects are perceived to have. Thus, when Norm, a normal perceiver, perceives a blue bead, the bead is perceived have a certain quality, perceived blueness. `Quality', here, is no mere synonym for property; rather, a quality is a kind of property a qualitative, as opposed to quan• titative, property. (The quantitative is a way of contrasting with the qualitative perhaps not the only way.).

Mill holds a metaphysical theory about the nature of things which is of the sensationalist or phenomenalist variety, and which he derives admittedly from the idealism of Berkeley. This metaphysical theory is introduced into a discussion in which he is attempting something different, namely, to offer a rival psychological account to Hamilton's intuitionist one of how it is that men possess that familiar but complex conception, Nature or the external world. It will be convenient to consider his psychological theory first.

The verb ‘to know’ can be used both in ascriptions of propositional knowledge and ascriptions of knowledge of acquaintance. In the formal epistemology literature, the former use of ‘know’ has attracted considerable attention, while the latter is typically regarded as derivative. This attitude may be unsatisfactory for those philosophers who, like Russell, are not willing to think of knowledge of acquaintance as a subsidiary or dependent kind of knowledge. In this paper we outline a logic of knowledge of acquaintance in (...) which ascriptions like ‘Mary knows Smith’ are regarded as formally interesting in their own right, remaining neutral on their relation to ascriptions of propositional knowledge. The resulting logical framework, which is based on Hintikka’s modal approach to epistemic logic, provides a fresh perspective on various issues and notions at play in the philosophical debate on acquaintance.

Wilfrid Sellars's "Empiricism and the Philosophy of Mind" begins with an argument against sense-datum epistemology. There is some question about the validity of this attack, stemming in part from the assumption that Sellars is concerned with epistemic foundationalism. This paper recontextualizes Sellars's argument in two ways: by showing how the argument of EPM relates to Sellars's 1940s work, which does not concern foundationalism at all; and by considering the view of H.H. Price, Sellars's teacher at Oxford and the only classical (...) datum theorist to receive substantive comment in EPM. Timm Triplett has claimed that Sellars's discussion simply begs the question against Price, but this depends on the mistaken assumption that Sellars's concern is with foundationalism. On the contrary, Sellars's argument concerns the assumption that the innate capacity for sensory experience counts as "thinking in presence" in the way needed for empiricist accounts of content acquisition. Price's distinction between noticing universals and being aware of them encapsulates the tensions empiricists face here. (shrink)

Coherence and correspondence are classical contenders as theories of truth. In this paper we examine them instead as interacting factors in the dynamics of belief across epistemic networks. We construct an agent-based model of network contact in which agents are characterized not in terms of single beliefs but in terms of internal belief suites. Individuals update elements of their belief suites on input from other agents in order both to maximize internal belief coherence and to incorporate ‘trickled in’ elements of (...) truth as correspondence. Results, though often intuitive, prove more complex than in simpler models (Hegselmann & Krause 2002, 2006; Grim, Singer, Reade & Fisher 2015). The optimistic finding is that pressures toward internal coherence can exploit and expand on small elements of truth as correspondence is introduced into epistemic networks. Less optimistic results show that pressures for coherence can also work directly against the incorporation of truth, particularly when coherence is established first and new data is introduced later.

What method should we use to determine the nature of perceptual experience? My focus here is the Kantian thought that transcendental arguments can be used to determine the nature of perceptual experience. I set out a dilemma for the use of transcendental arguments in the philosophy of perception, one which turns on a comparison ofthe transcendental method with the first-personal method of early analytic philosophy, and with the empirical methods of much contemporary philosophy of mind. The transcendental method can avoid (...) this dilemma only if it commits to our possessing a capacity for imaginative reflection, one which is capable of identifying certain formal properties of experience.This result indicates some of the commitments which must be made if transcendental arguments are to be used in the philosophy of perception, and it has implications for those views that take the philosophy of perception to be autonomous of the empirical science of perception.

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.

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)

Byrne & Hilbert defend color realism, which assumes that: (a) colors are properties of objects; (b) these objects are physical; hence, (c) colors are physical properties. I accept (a), agree that in a certain sense (b) can be defended, but reject (c). Colors are properties of perceptual objects – which also have underlying physical properties – but they are not physical properties.

One increasingly popular view in the philosophy of perception isexternalismabout sensible qualities, according to which sensible qualities such as colors, smells, tastes, and textures are features, not of our minds, but of mind-independent, external objects in the world. The primary motivation for this view is that perceptual experience seems to betransparent—that is, when we attend to sensible qualities, it seems like what we are attending to are features of external objects, not our own minds. Most (if not all) externalists are (...) either naïve realists or externalist representationalists. However, in this article, I argue that those who are moved by the primary motivation for externalism should instead be sense-datum theorists, for externalists’ primary motivation supports the sense-datum theory, not their actually favored views. I argue that externalists should focus on different motivations, get new ones, or become sense-datum theorists. (shrink)

To be acquainted with something (in the philosophical sense of “acquainted” discussed here) is to be directly aware of it. The idea that we are acquainted with certain things we experience has been discussed throughout the history of Western Philosophy, but in the early 20th century it gained especially focused attention among analytic philosophers who drew their inspiration from Bertrand Russell's work on acquaintance. Since then, many philosophers—particularly those working on self‐knowledge or perception—have used the notion of acquaintance to explain (...) various facts about human experience and knowledge. In this paper, I offer an overview of this work, with particular focus on the resurgent literature on acquaintance in contemporary analytic philosophy. After more fully explaining what acquaintance is (or is supposed to be), I describe some reasons for thinking that we are indeed acquainted with certain things we experience, and then I survey some of the facts about experience and knowledge that acquaintance may help explain.

I argue that the direct perception of emotion (DP) is best conceived in terms of event perception, rather than fact perception or object perception. On neither of these two traditional models can the perception of emotion be as direct as its counterpart in ordinary perception; the proponent of DP must either drop the ‘direct’ claim or embrace a part-whole model of emotion perception and its problems. But our best account of how we perceive events directly can be applied to emotion (...) perception without any loss in directness. Not only this but there are good reasons to think that such a conception better respects both empirical evidence and the phenomenology of emotion perception. (shrink)

In this paper we set out a view on which internalist proper basicality is secured by sensory experience.

I argue that scientism in general is best understood as the thesis that the boundaries of the natural sciences should be expanded in order to include academic disciplines or realms of life that are widely considered not to belong to the realm of science. However, every adherent and critic of scientism should make clear which of the many varieties of scientism she adheres to or criticizes. In doing so, she should specify whether she is talking about (a) academic or universal (...) scientism, (b) reductive, methodological, epistemological, ontological, moral, or existential, scientism, (c) full or partial scientism, (d) strong or weak scientism, and (e) in the case of moral and existential scientism: replacement or illusion scientism. The strongest version of scientism one could defend is a conjunction of the following theses: strong full epistemological scientism, strong full ontological scientism, strong full Illusion-moral scientism, strong Illusion-existential scientism, and strong full reductive scientism. After a detailed discussion of each of the main varieties of scientism and their interrelations, the paper provides a conceptual map, consisting of two figures, which displays the main varieties of scientism and the relations that obtain between them, primarily, those of implication and mutual exclusion.

This text aims at presenting a general characterization of the act of perceiving a particular object, in a framework in which perception is conceived of as a mental and cognitive faculty having specific functions that other faculties such as imagination and memory do not possess. I introduce the problem of determining the occurrence of singular perception of a physical object, as opposed to the occurrence of other mental states or attitudes. I propose that clarifying this occurrence problem requires making explicit (...) the conditions of perceptual competence/faculty so as to explain the occurrence of each perceptual performance on the basis of the use of this competence. I argue then for a direct relational model according to which the singular perception of an object depends on a competence of connecting the perceiver directly with each target object. This model is compatible with a disjunctive approach to perception according to which each particular experience of an object corresponds either to a direct perceptual relation with this object or to the illusion of having the experience of this object. The arguments in favour of this relational model rest on the idea that the faculty of perception grounds the capacity to demonstratively identify physical objects. (shrink)

I raise some objections to the theory presented in *Outside Color*.

We begin with a theory of the structure of sensory consciousness; a target phenomenon of 'presentation' can be clearly located within this structure. We then defend the rational-psychological necessity of presentation. We conclude with discussion of these philosophical challenges to the possibility of presentation. One crucial aspect of the discussion is recognition of the <cite>nonobjectivity</cite> of consciousness (a technical appendix explains what I mean by that). The other is a full-faced stare at the limitations of rational psychology: much of the (...) dialectic in the philosophy of perception pertains to matters beyond the limits of coherence---a breakwater against which philosophy crashes, and rolls back.

It will be obvious to anyone with a slight knowledge of twentieth-century analytic philosophy that one of the central themes of this kind of philosophy is the nature of perception: the awareness of the world through the five senses of sight, touch, smell, taste, and hearing. Yet it can seem puzzling, from our twenty-first-century perspective, why there is a distinctively philosophical problem of perception at all. For when philosophers ask ‘what is the nature of perception?’, the question can be confused (...) with other, purely empirical, questions. For example: how do our sense-organs actually work? What are the mechanisms of smell and taste? How do vision and touch actually provide us with information about the world around us? There is much general agreement, in its broad outlines, about how to answer such questions empirically; but it is not clear what role, if any, philosophy has to play in answering these empirical questions. So if these were the only questions about the nature of perception, then it would not be clear exactly what the philosophy of perception is supposed to be about. (shrink)

This is the introductory essay to the collection of essays: 'Acquaintance: New Essays' (eds. Knowles & Raleigh, forthcoming, OUP). In this essay I provide some historical background to the concept of acquaintance. I examine various Russellian theses about acquaintance that contemporary acquaintance theorists may wish to reject. I consider a number of questions that acquaintance theorists face. I provide a survey of current debates in philosophy where acquaintance has recently been invoked. And I also provide brief summaries of the other (...) essays in this volume. (shrink)

The debate between relationalism and representationalism in the philosophy of perception seems to have come to a standstill where opponents radically disagree on methodological principles or fundamental assumptions. According to Fish (this volume) this is because, not unlike Kuhnian scientific paradigms, the debate displays some elements of incommensurability. This diagnosis makes advancing the debate impossible. I argue that what is hindering progress is not a clash of research programmes, but a series of misunderstandings that can be avoided by disentangling the (...) different questions each theory is invested in and by making explicit the hidden assumptions at play in the debate. One such central assumption is what I call the Superficiality Constraint. This is the idea that the phenomenal character of experience is superficial with respect to introspection. I argue that we can make progress in the debate by assessing to what extent and at what cost relationalism can accommodate this constraint. (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)

This paper elaborates on an argument in my book *Perception*. It has two parts. In the first part, I argue against what I call "basic" naive realism, on the grounds that it fails to accommodate what I call "internal dependence" and it requires an empirically implausible theory of sensible properties. Then I turn Craig French and Ian Phillips’ modified naïve realism as set out in their recent paper "Austerity and Illusion". It accommodates internal dependence. But it may retain the empirically (...) implausible theory of sensible properties. And it faces other empirical problems. Representationalism about experiences avoids those problems and is to be preferred. (shrink)

In the philosophy of perception, direct realism has come into vogue. Philosophical authors assert and assume that what their readers want, and what anyone should want, is some form of direct realism. There are disagreements over precisely what form this direct realism should take. The majority of positions in favor now offer a direct realism in which objects and their material or physical properties constitute the contents of perception, either because we have an immediate or intuitive acquaintance with those objects (...) and properties, or because our perceptual states have informational content that represents the properties of those objects (and which is not itself an object of perception and has no specifically subjective aspect). This paper considers various forms of perceptual realism, including, for purposes of comparison, the largely abandoned indirect or representative realism. After surveying the variety of perceptual realisms and considering their various commitments, I introduce some considerations concerning the phenomenology of visual space that cause trouble for most forms of direct realism. These considerations pertain to the perception of objects in the distance and, secondarily, to the perception of shapes at a slant. I argue that one of the lesser known varieties of perceptual realism, critical direct realism, can meet the challenges offered by the facts of spatial 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)

In his book “Seeing Dark Things” (2008), Roy Sorensen provides many wonderfully ingenious arguments for many surprising, counter-intuitive claims. One such claim in particular is that when we a silhouetted object – i.e. an opaque object lit entirely from behind – we literally see its back-side – i.e. we see the full expanse of the surface facing away from us that is blocking the incoming light. Sorensen himself admits that this seems a tough pill to swallow, later characterising it as (...) “the most controversial thesis of the book” (2011, p199). -/- I will argue against Sorensen’s controversial thesis and in favour of what seems to me to be a much more natural and commonsensical alternative: when we see a silhouetted object, what we see is its edge and only its edge – so we do not see its entire back-side.

Consider three answers to the question of what it actually is for you to be aware of the room you are in. It is for the room in a way to exist. It is for there to be only physical activity in your head, however additionally described. It is for there to be non-spatial facts somehow in your head. The first theory, unlike the other two, satisfies five criteria for an adequate account of consciousness itself. The criteria have to do (...) with the seeming nature of this consciousness, and with subjectivity, reality including non-abstractness, mind-body causation, and the differences between perceptual, reflective and affective consciousness. The theory of consciousness as existence is not open to the objection having to do with a deluded brain in a vat. The theory, as any theory of consciousness needs to, explains its own degree of failure in characterizing consciousness. It releases neuroscience and cognitive science from nervousness about consciousness, and leaves all of consciousness a subject for science. The theory is a reconstruction of our conception of consciousness. It may be that we should carry forward several theories of consciousness. But they will have to be compared in terms of truth to the five criteria for an adequate theory. (shrink)

How do I know that I see a cat? A curiously under-asked question. The paper tries to answer it.

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.

What is the distinctively philosophical problem of perception? Here it is argued that it is the conflict between the nature of perceptual experience as it intuitively seems to us, and certain possibilities which are implicit in the very idea of experience: possibilities of illusion and to the world' which involves direct awareness of existing objects and their properties. But if one can have an experience of the same kind without the object being there -- a hallucination of an object -- (...) then it seems that perceptual experience cannot essentially be such a relation. This is the fundamentally philosophical problem of perception; the various philosophical theories of perception in the 20th and 21st centuries can be seen as responses to it. (shrink)

When we perceive we are under the impression of being directly aware of concrete, mindindependent objects. We also consider perception as a basic, reliable source for acquiring beliefs and an effective means for coping with the environment. In the philosophical literature, this direct and basic character of perception is sometimes captured by saying that perception is openness to the world. Articulating, refining and vindicating as far as possible this commonsensical view of perception as openness to the world is the main (...) objective of this work. In order to make the metaphor of openness tractable in theoretical terms, I set up the dialectic in terms of a contrast between representationalism, which holds that perception represents things as being a certain way, and pure relationalism, which holds that perception can be openness to the world only by being a non-representational relation between a subject and objects in the world. The main thesis that I defend with several arguments in this work is that perception is both representational and relational. Indeed, it intelligibly relates us to the world in virtue of its representational content. In chapter one, I place perception in the broader context of intentional states. I articulate a view on which intentional states are directed toward their objects in virtue of having representational content, and show that prima facie the arguments for thinking that paradigmatic intentional states such as belief have content apply to perception too. I also explain why pure relationalists would reject the application of the content-model to perception. Chapter two is devoted to Charles Travis’s argument that perceptual experience does not have content. I counter his argument by offering a phenomenological account of perceptual constancy, and I show that content is necessary for capturing constancy in theoretical terms. Further, I argue that content helps us to better explain how the mind-independent nature of concrete objects is manifest in the phenomenology of perceptual experience. Chapter three concerns the question of how we should elucidate perceptual experience as openness to the world in the face of illusion and hallucination. I consider three possible approaches, and I argue that a view on which perceptual experience is both representational and relational can best make sense of the relevant phenomena. In the fourth chapter, I consider the debate on phenomenal character between representationalist and purely relationalist views in light of a distinction between particularity and generality. I show how representationalists are committed to there being an element of generality in perception, and how pure relationalists construe perception as wholly particular instead. I defend the representationalist view on the grounds that generality is necessary to make sense of the phenomenal and epistemic determinacy of perception. In the concluding remarks, I consider the question of whether my view can make room for the relationality of perception, and I argue again that only a distorted view of the metaphor of openness to the world could lead one to think that content and relationality are incompatible.

This dissertation proposes the central elements of a Social Enactive Theory of Perception. According to SEP, perception consists in sensory-based practices of interaction with objects, events, and states of affairs that are socially constituted. I oppose the representational view that perception is an indirect contact with the world, consists of the passive receiving and processing of sensory input, is in need of constant assessment of accuracy, and is a matter of individuals alone. I share the basic enactivist insight that perception (...) is a type of activity, but I depart from standard enactivism on the grounds of its individualistic bias and its limited conception of activity. Instead of motor actions, I formulate the concept of perceptual practices as the appropriate framework to understand perception. Perception is woven into socially informed, contextual, sensory-based everyday activities, such as food, dance, and dress, and even seemingly independent, basic perceptual activities and concepts are constituted by such practices. Perceptual individual interactions instantiate social perceptual practices but are not just repetitions of a script. We perceive objects in virtue of perspectives or appearances, not in spite of them, and on this basis I offer SEPâs take on experience, properties, and contents. I conceive perceptual experience as finely grained interactions between subjects and objects, both of which are spatially, temporally, and pragmatically situated. Objects and their sensory properties are perceived dynamically and always in multiple appearances. Perceptual content offers a pragmatic specification of the perceptual objects in the specific ways they appear to subjects. For SEP, perception is normatively structured. SEPâs perceptual normativity is not a worry about a supposed constant threat that our perceptions be nonveridical, but about the placement of perceptual things in a system of possibilities and expectations, cast in terms of degrees of fulfillment of expectations and in a horizon of pragmatic significance, both of which are functions of the socially constituted interactions between a perceiver and a rich theory of appearances.

Many of our ordinary beliefs about the world around us are a result of inference from more fundamental beliefs. Foundationalists in epistemology have thought that, if these ordinary beliefs are to be rationally justified, the chain of inferential justification must terminate in a belief that is justified noninferentially. Foundationalists, of the internalist variety, have thought that the most plausible candidates for ending the regress of empirical justification are experiential states, the justifying features of which the believing subject is aware. The (...) Sellarsian dilemma, taking its name from philosopher Wilfrid Sellars, has been a persistent argument against foundationalist theories of epistemic justification. There have been various formulations of the dilemma over the years, but in its most general form it says that for any construal of an experiential state where the experiential state provides justification, the experiential state will need further justification. Sellars thought that an experience, all by itself, cannot provide justification unless we apply concepts to the experience. However, the application of concepts is judgmental and conceptual judgments, like beliefs, require further justification. So, the experiential state construed this way would perpetuate the regress it was designed to terminate. On the other hand, if the experiential state is construed such that it is not in need of justification, then it cannot itself provide justification. Both options are devastating to a foundationalist epistemology. My thesis is that a solution to all forms of the Sellarsian dilemma is to require for foundational justification direct awareness of the fit between one's conceptual judgment and the justifying experiential state. I concede that one must conceptualize one's experiential states for these states to play an epistemic role. However, I argue that conceptual judgments of this sort are the foundations. The importance of this solution is that it not only terminates the regress of justification but it also captures the primary intuitions that motivate internalism and foundationalism. This is to say that although I have framed my account as a response to the Sellarsian dilemma, it is not merely an ad hoc patch that avoids what stood as a serious problem. Instead, it is a return to what has motivated and what I take to be most persuasive about internalist foundationalism. (shrink)

Defenders of the Knowledge Argument contend that physicalism is false because knowing all the physical truths is not sufficient to know all the truths about the world. In particular, proponents of the Knowledge Argument claim that physicalism is false because the truths about the character of conscious experience are not knowable from the complete set of physical truths. This dissertation is a defense of the Knowledge Argument. Chapter one characterizes what physicalism is and provides support for the claim that if (...) knowing all the physical truths is not sufficient to know all the truths about the world, then physicalism is false. In chapter two, I defend the claim that knowing all the physical truths is not sufficient for knowing all the truths about the world. In addition to mounting a prima facie case for the knowledge intuition, I present and defend an epistemology grounded in direct acquaintance to provide a more substantive argument to accept it. Chapters three through five address the physicalist objections to the Knowledge Argument. The first set of objections advocates that knowing all the physical truths is, in fact, sufficient for knowing all the truths about the world. The next set of objections admits that there is some sense in which knowing all the physical truths is not sufficient for knowing all the truths about the world. However, these objections maintain that the kind of knowledge that is absent from the complete set of physical truths is know-how or knowledge by acquaintance, and not factual or propositional knowledge. The final set of objections maintain that the kind of propositional knowledge that is left out of the complete set of physical truths is compatible with physicalism. My response to these objections is part of advancing my prima facie case for the Knowledge Argument. The final chapter addresses a structural question that pertains to the Knowledge Argument. Some philosophers have maintained that the structure of the Knowledge Argument invites a kind of self-refutation of any systematic account of reality. The concern is that the Knowledge Argument proves too much, and that the dualist who uses the argument to refute physicalism risks the argument defeating his own position. I will argue that the Knowledge Argument does not refute dualism. (shrink)
