According to Paul Snowdon, one directly perceives an object x iff one is in a position to make a true demonstrative judgement of the form “That is x”. Whenever one perceives an object x indirectly (or dependently , as Snowdon puts it) it is the case that there exists an item y (which is not identical to x) such that one can count as demonstrating x only if one acknowledges that y bears a certain relation to x. In this paper (...) I argue that what we hear directly are sounds, and that material objects (such as violins and goldfinches) are only indirectly heard. However, there are cases of auditory object perception that should count as direct : Some blind persons’ ears are so sensitive to the way sound waves are modified by things in their surroundings that they can detect objects such as other persons, fences or trees. Interestingly, objects localized in this way make themselves felt via a kind of pressure in the perceiver’s face (that is why the phenomenon is commonly called “facial vision”), the perception is phenomenally quite different from hearing. Since, to some degree, most people are able to conclude from the way it sounds that, say, they stand at the foot of a concrete wall (when there is enough traffic noise around), we can imagine situations where two persons perceive the same wall, one indirectly (demonstratively apprehending sounds) and the other directly (demonstratively apprehending nothing but the wall). These cases invite us to discuss the role phenomenology plays in determining whether an object is perceived directly or indirectly. (shrink)

What is the contrary of pleasure? “Pain” is one common answer. This paper argues that pleasure instead has two natural contraries: unpleasure and hedonic indifference. This view is defended by drawing attention to two often-neglected concepts: the formal relation of polar opposition and the psychological state of hedonic indifference. The existence of mixed feelings, it is argued, does not threaten the contrariety of pleasure and unpleasure.

This article examines a somewhat neglected argument for the existence of God which appeals to the divine perspective as a way of reconciling the conflicting claims of realism and anti-realism. Six representative examples are set out (Berkeley, Ferrier, T. H. Green, Josiah Royce, Gordon Clark and Michael Dummett), reasons are considered why this argument has received less attention than it might, and a brief sketch given of the most promising way in which it might be developed.

This paper presents structural similarities and historical connections between Prior’s rejection of the Barcan formula and his critique of Berkeley’s master argument for idealism in his 1955 paper “Berkeley in Logical Form”. Making use of Mackie’s paper “Self-Refutation—A Formal Analysis”, it concludes with some suggestions concerning what is at stake in the debate between Prior and Berkeley and in structurally similar debates such as whether to accept the Barcan formula.

I here discuss Hegel's rule-following considerations as they are found in the first four chapters of his Phenomenology of Spirit. I begin by outlining a number of key premises in Hegel's argument that he adopts fairly straightforwardly from Kant's Transcendental Deduction. The most important of these is that the correctness or incorrectness of one's application of a rule must be recognizable as such to the rule-follower. Supplementing Hegel's text as needed, I then argue that it is possible for an experiencing (...) subject to follow a rule only where there is a community of individuals whose agreement can provide a standard for the correctness and incorrectness of his use. I further argue that a community must consist of members that are compresent, and thus that a collection of time-slices of an individual will not serve this purpose. I conclude by raising a potential problem for Hegel's account of rule-following concerning the correctness and incorrectness of the judgments of a community, and pointing to a possible line of response to this problem.

Many philosophers still countenance senses or meanings in the broadly Fregean vein. However, it is difficult to posit the existence of senses without positing quite a lot of them, including at least one presenting every entity in existence. I discuss a number of Cantorian paradoxes that seem to result from an overly large metaphysics of senses, and various possible solutions. Certain more deflationary and nontraditional understanding of senses, and to what extent they fare better in solving the problems, are also (...) discussed. In the end, it is concluded that one must divide senses into various ramified-orders in order to avoid antinomy, but that the philosophical justification of such orders is, as yet, still somewhat problematic.

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.).

Before the law sits a gatekeeper. To this gatekeeper comes a man from the country who asks to gain entry into the law. But the gatekeeper says that he cannot grant him entry at the moment. The man thinks about it and then asks if he will be allowed to come in sometime later on. “It is possible,” says the gatekeeper, “but not now.”—Franz Kafka..

As standardly conceived, an illusion is an experience of an object o appearing F where o is not in fact F. Paradigm examples of color illusion, however, do not fit this pattern. A diagnosis of this uncovers different sense of appearance talk that is the basis of a dilemma for the standard conception. The dilemma is only a challenge. But if the challenge cannot be met, then any conception of experience, such as representationalism, that is committed to the standard conception (...) is false. Perhaps surprisingly, naïve realism provides a better account of color illusion.An apparence ymaad by som Magyk. Chaucer. (shrink)

I propose that the fundamental challenge Berkeley left realists is to account for experiences’ ability to present items as mind-independent, consistent with the claim that experiences always present themselves among the items of awareness. By exploring two ways of responding to this challenge, and ruling out the second, I hope to show that realists aiming to secure a role for experiences in grounding our grasp of mind-independence need to adopt a specific view of perceptual experience. They must take experiences to (...) have translucent aspects, and accord such aspects an essential role in presenting us with a mind-independent world. (shrink)

Sir William Drummond (1770?-1828) enjoyed considerable notoriety in the early nineteenth century as the author of the Academical Questions (1805), a manifesto for immaterialism that is at the same time a creative synthesis of ancient and modern forms of scepticism. In this paper I advance an interpretation of Drummond's work that emphasises his extensive employment and adaptation of Hume's own ‘Academical or Sceptical Philosophy’. I also document the impact of the Academical Questions on the contemporary philosophical scene, including its decisive (...) influence on Shelley's philosophical development. (shrink)

Hans Vaihinger, in the late nineteenth century, posed a now famous trilemma for Immanuel Kant's theory of affection: If things-in-themselves are the affecting objects, then one must apply the categories beyond the conditions of their application . If one holds that appearances are the affecting objects, then one must hold that these appearances which are the effects of affection are themselves the causes of affection. If one holds that things-in-themselves affect the noumenal self in parallel with appearances affecting the empirical (...) self, then that which is a representation for the noumenal self must serve as a causally efficacious thing-in-itself for the empirical self's production of an empirical representation of the very same object.

In this paper, I argue that there is a sceptical argument against the senses advanced by Hume that forms a decisive objection to the Metaphysically Realist interpretations of his philosophy – such as the different naturalist and New Humean readings. Hume presents this argument, apparently starting with the primary/secondary qualities distinction, both in A Treatise of Human Nature, Book 1, Part 4, Section 4 (Of the modern philosophy) (1739) and An Enquiry concerning Human Understanding, Section 12 (Of the Academical or (...) Sceptical Philosophy), paragraphs 15 to 16 (1748). The argument concludes with the contradiction between consistent reasoning (causal, in particular) and believing in the existence of Real (distinct and continued) entities. The problem with the Realist readings of Hume is that they attribute both to Hume. So their Hume is a self-reflectively inconsistent philosopher. I show that the various ways to avoid this problem do not work. Accordingly, this paper suggests a non-Realist interpretation of Hume's philosophy: Hume the philosopher suspends his judgment on Metaphysical Realism. As such, his philosophical attitude is neutral on the divide between materialism and idealism. (shrink)

Sensationalistic Phenomenalism and Economy of Thought. On Ernst Mach's Concept of Science. Ernst Mach, natural scientist and major precursor of the Vienna Circle, never wants to be a philosopher. Nevertheless his writings are full of valuable hints for a modern theory of human knowledge – with respect to economical, historical and evolutionary aspects. His kind of phenomenalism is sensationalistic, monistic and instrumentalistic. This article deals with some contributions of his approach to actual debates in the general philosophy of science.

Trisvabh vanirdeśa (Treatise on the Three Natures) is Vasubandhu's most mature and explicit exposition of the Yogc c ra doctrine of the three natures and their relation to the Buddhist idealism Vasubandhu articulates. Nonetheless there are no extent commentaries on this important short test.

In the opening section of this paper we spell out an account of our na ve view of bodily sensations that is of historical and philosophical significance. This account of our shared view of bodily sensations captures common ground between Descartes, who endorses an error theory regarding our everyday thinking about bodily sensations, and Berkeley, who is more sympathetic with common sense. In the second part of the paper we develop an alternative to this account and discuss what is at (...) stake in deciding between these two ways of understanding our everyday view. In the third and final part of the paper we offer an argument in favour of our alternative. (shrink)

Although coming from two very different paths, both Kant and Patañjali present similar strategies to refute the skeptic argument that denies the real and independent existence of physical objects. This essay examines both strategies through the reconstruction of Kant’s and Patañjali’s twofold refutation of idealism: one based on the perceptual distinction between the real and the illusory, and the other one based on the ontological necessity of a permanent external object to understand change. I argue that the second strategy is (...) philosophically stronger due to its phenomenological recognition of the body as a grounding point, and that this is possible only on account of an anti-realist conception of time. Both Kant and Patañjali utilize a similar line of realist argumentation while diverging in the type of realism that they each hold. (shrink)

This paper presents the content of the unpublished notes that the Dutch mathematician Arend Heyting wrote in different periods of his life on solipsism and that are preserved in Heyting's archive at the University of Amsterdam. Most of the notes are quoted here and translated into English. Their study shows the originality of Heyting's reflections on a subject that was typical of his master, L. E. J. Brouwer, the father of intuitionism.

The later Wittgenstein advanced a revolutionary but puzzling conception of how philosophy ought to be practised: Philosophical problems are not to be coped with by establishing substantive claims or devising explanations or theories. Instead, philosophical questions ought to be treated ‘like an illness’. Even though this ‘non-cognitivism’ about philosophy has become a focus of debate, the specifically ‘therapeutic’ aims and ‘non-theoretical’ methods constitutive of it remain ill understood. They are motivated by Wittgenstein’s view that the problems he addresses result from (...) misinterpretation, driven by ‘urges to misunderstand’. The present paper clarifies this neglected concept and analyses how such ‘urges’ give rise to pseudo-problems of one particular, hitherto little understood, kind. This will reveal ‘therapeutic’ aims reasonable and ‘non-theoretical’ methods necessary, in one clearly delineated and important part of philosophy. I.e.: By developing a novel account of nature and genesis of one important class of philosophical problems, the paper explains and vindicates a revolutionary reorientation of philosophical work, at the level of both aims and methods.

Abstract: The notion that philosophy can be practised as a kind of therapy has become a focus of debate. This article explores how philosophy can be practised literally as a kind of therapy, in two very different ways: as philosophical therapy that addresses “real-life problems” (e.g., Sextus Empiricus) and as therapeutic philosophy that meets a need for therapy which arises in and from philosophical reflection (e.g., Wittgenstein). With the help of concepts adapted from cognitive and clinical psychology, and from cognitive (...) linguistics, the article shows that both philosophical projects address important and literally therapeutic tasks and explains how they can do so with genuinely philosophical argument and analysis. This brings into view new applications for philosophy, a need for therapy in core areas of the subject, and the outline of a new approach to meet what will be shown to be a central need. (shrink)

This volume is about the many ways we perceive. Contributors explore the nature of the individual senses, how and what they tell us about the world, and how they interrelate. They consider how the senses extract perceptual content from receptoral information. They consider what kinds of objects we perceive and whether multiple senses ever perceive a single event. They consider how many senses we have, what makes one sense distinct from another, and whether and why distinguishing senses may be useful. (...) They consider the extent to which the senses act in concert, rather than as discrete modalities, and whether this influence is epistemically pernicious, neutral, or beneficial. They explore both the familiar five sense modalities and other candidate sense modalities, including a sense for flavour, inner senses (e.g., a sense for pain), and various senses that may result from using sensory substitution devices. Contributors often represent competing views, and the methods they deploy sometimes differ from one essay to the next—with some drawing upon the sciences and engineering and others relying upon conceptual analysis. All contributors agree, nonetheless, that traditional theorizing about the senses is hampered by a neglect of the senses other than vision, and by the misconception that vision is a passive receptacle for an image thrown by a lens. And many contributors believe that it is unduly restrictive to think of perception as a collation of contents provided by individual sense modalities; they think that to understand perception properly, we need to build into our accounts the idea that the senses work together. The ambition of the volume is to begin to develop better paradigms for understanding the senses, and thereby to move toward a better understanding of perception. (shrink)

This dissertation aims to revive wave theory in the philosophy of sound. Wave theory identifies sounds with compression waves. Despite its wide acceptance in the scientific community as the default position, many philosophers have rejected wave theory and opted for different versions of distal theory instead. According to this current majority view, a sound has its stationary location at its source. I argue against this and other alternative philosophical theories of sound and develop wave theory into a more defensible form. (...) Philosophers of sound tend to emphasise how sounds are experienced to be in their arguments. Most often, it is assumed that that which appears to be a distally located bearer of auditory properties in an auditory experience is a sound. Chapter 1 argues that if this distal entity is the sound source instead, many of the existing theories of sound will be severely affected. Chapter 2 discusses auditory perception and criticises the common assumption that we hear non-sound entities in virtue of hearing sounds. I show that this assumption begs the question against certain theories of sound and that the contrary view that sound sources can be directly heard is more plausible. If sound sources can be directly heard, then features commonly attributed to sounds based on auditory experiences might rather be features of sound sources. I examine eight of such features in Chapter 3. Only four of them survive. Chapters 4 and 5 review the existing theories of sound. After a taxonomy of existing theories of sound, each theory is criticised one-by-one. Some of them are problematic precisely because they rely on the implausible assumption that that which appears to be distally located in an auditory experience is a sound rather than a sound source. Lastly, Chapter 6 focuses on wave theory. It begins with two positive arguments for wave theory in general, followed by my replies to two common objections in the literature. I then move on to develop my version of wave theory. There are two core aspects of my view. The first one is a metaphysics of compression waves; the second is an account of what it is to hear compression waves. After comparing my view with a similar theory, I demonstrate the explanatory power of my view in two steps. First, the eight commonly accepted features of sounds examined in Chapter 3 are revisited. It turns out that my view can accommodate all of them. Second, explanations for four special sound-related phenomena are offered at the end of the chapter. I conclude in the last chapter with the suggestion that, as a philosopher, the best way to defend wave theory is to offer a better understanding of auditory perception which explains how compression waves are experienced.

An introductory overview of the main issues in the epistemology of perception.

To imagine is to form a mental representation that does not aim at things as they actually, presently, and subjectively are. One can use imagination to represent possibilities other than the actual, to represent times other than the present, and to represent perspectives other than one’s own. Unlike perceiving and believing, imagining something does not require one to consider that something to be the case. Unlike desiring or anticipating, imagining something does not require one to wish or expect that something (...) to be the case. // -/- Imagination is involved in a wide variety of human activities, and has been explored from a wide range of philosophical perspectives. Philosophers of mind have examined imagination’s role in mindreading and in pretense. Philosophical aestheticians have examined imagination’s role in creating and in engaging with different types of artworks. Epistemologists have examined imagination’s role in theoretical thought experiments and in practical decision-making. Philosophers of language have examined imagination’s role in irony and metaphor. // -/- Because of the breadth of the topic, this entry focuses exclusively on contemporary discussions of imagination in the Anglo-American philosophical tradition.

Sense data are the alleged mind-dependent objects that we are directly aware of in perception, and that have exactly the properties they appear to have. For instance, sense data theorists say that, upon viewing a tomato in normal conditions, one forms an image of the tomato in one's mind. This image is red and round. The mental image is an example of a “sense datum.” Many philosophers have rejected the notion of sense data, either because they believe that perception gives (...) us direct awareness of physical phenomena, rather than mere mental images, or because they believe that the mental phenomena involved in perception do not have the properties that appear to us (for instance, I might have a visual experience representing a red, round tomato, but my experience is not itself red or round). Defenders of sense data have argued, among other things, that sense data are required to explain such phenomena as perspectival variation, illusion, and hallucination. Critics of sense data have objected to the theory's commitment to mind-body dualism, the problems it raises for our knowledge of the external world, its difficulty in locating sense data in physical space, and its apparent commitment to the existence of objects with indeterminate properties.

My dissertation contributes to a central and ongoing debate in the philosophy of perception about the fundamental nature of perceptual states. Such states include cases like seeing, hearing, or tasting as well as cases of merely seeming to see, hear, or taste. A central question about perceptual states arises in light of misperceptual phenomena. A commonsensical view of perceptual states construes them as simply relating us to the external and mind independent objects. But some misperceptual cases suggest that these states (...) fall short of contact with the world. The result is that perceptual states are either thought to fundamentally consist in a highest common factor that falls short of perceptual contact with the world, or are thought to be disjunctive in nature, with some cases involving perceptual contact, and others receiving a different analysis. Contrary to these views, I argue that no misperceptual cases compromise perceptual contact with worldly objects, so perceptual states should be understood as relations to the external and mind-independent world. I call this view I defend Pure Relationalism, and the view of misperceptual cases that makes pure relationalism possible Illusionism. (shrink)

The Abrahamic traditions regard God as the world’s author. But what kind of author? A novelist? A playwright? Perhaps a composer of classical music? I will argue that it is best to regard God as like an improvisational play director or the leader of a jazz ensemble. Each determines the broad melodic contours or coarse-grained plot beforehand, while allowing their musicians or actors, and chance, to fill in the more fine-grained details. This analogy allows us to regard God as the (...) ultimate author of this world, while allowing us to be, while less than co-authors, more than mere enactors of a pre-written piece. These metaphors are particularly well-suited to illustrate and flesh out an Open Theistic view of things. (shrink)

This paper reviews four current theories of brain-consciousness relations—classical Cartesian Dualism, the Identity Theory, Eliminative Materialism, and a new form of Substance Dualism that includes a modified form of the Cartesian theory. This entails a critical examination of our basic concepts of what consciousness is, of the nature of the body image, and the relation of phenomenal space to physical space. This investigation reaches the same result as that attained recently by the physicist Bernard Carr (2008)—that what is needed is (...) a paradigm shift in our basic concepts of the geometry of the Universe. In order to understand phenomenal consciousness we need to replace the present four-dimensional model with a higher-dimensional structure, in which a phenomenal space (with its contents) and physical space (with its contents) are different cross-sections (branes) of a higher-dimensional space (the bulk). Keywords: brain—consciousness—mechanisms—substance dualism—brane theory. (shrink)

I defend a solution to a long-standing problem with perceptual appearances, brought about by the phenomenon of perceptual constancy. The problem is that in conditions which are non-ideal, yet within the range that perceptual constancy works, we see things veridically despite an “appearance” which is traditionally taken to be non-veridical. For example, a tilted coin is often taken to have an “elliptical appearance”, shadowed surfaces a “darker appearance”. These appearances are puzzling for a number of reasons. I defend and elaborate (...) on an approach taken by Sean Kelly, and earlier by the art historian E.H. Gombrich, according to which we can be tricked by our ability to bring about a kind of Gesltalt shift between different possible perceptual interpretations of a scene. (shrink)

It is often thought that sensible qualities such as colours do not exist as properties of physical objects. Focusing on the case of colour, I discuss two views: the Galilean view, according to which colours do not exist as qualities of physical objects, and the naive view, according to which colours are, as our perception presents them to be, qualities instantiated by physical objects. I argue that it is far from clear that the Galilean view is better than the naive (...) view. Given the arguments in this paper, the naive view ought to be taken seriously. The discussion here appeals especially to theorists who, like Goff, are already convinced that the quantitative language of physical science fails to capture all qualities. (shrink)

Many philosophical issues concern questions of objectivity and subjectivity. Of these questions, there are two kinds. The first considers whether something is objective or subjective; the second what it _means_ for something to be objective or subjective.

In this paper, I argue that Hume has an insight into the heart of most of “new philosophy” when he claims that according to it, proper sensibles are not Real properties of material substance and Real bodies. I call this tenet “the Proper Sensibles Principle” (PSP). In the second part of the paper, I defend the interpretation - mainly against Don Garrett’s doubts - that the PSP is a rational tenet in Hume’s view and he thus endorses it. Its rationality (...) means that the PSP has a firm foundation in inductive-causal reasoning. (shrink)

My aim in this research is to study the philosophical problems of intentionality and perception by critically analyzing the relevant ideas from John Searle’s works, and also to attempt to give solutions to some of these problems. I try to elucidate Searle's theory of intentionality and his way of assimilating the problems of perception into this theory, and investigate the plausibility of his corresponding ideas in the context of ongoing debates.

In a recent paper, Haig and Borsboom explore the relevance of the theory of truth for psychological science. Although they conclude that correspondence theories of truth are best suited to offer the resources for making sense of scientific practice, they leave open the possibility that other theories might accomplish those same ends. I argue that deflationary theories of truth, which deny that there is any substantive property that unifies the class of truths, makes equally good sense of scientific practice as (...) the correspondence theory, but at lesser theoretical cost. I also argue that the considerations Haig and Borsboom draw on are better thought of as issues relevant to realism, and thus separate from the theory of truth. I conclude that while they are correct to engage questions about what makes true the various claims that arise in psychological research, they may do so without saddling themselves with a correspondence theory.

On the assumption that we may learn from our elders and betters, this paper approaches some fundamental questions in perceptual epistemology through a dispute between McDowell and Wright about external world scepticism.

Amongst those who answered Molyneux’s question in the negative or at least not in the positive, George Berkeley is of particular interest because he argued for a very radical position. Most of his contribution to the discussion can be found in his Essay towards a New Theory of Vision. I will give an exposition of his view (2) and then move on to a critical discussion of this kind of view, - what one could call the “Berkeleian view” (3). I (...) think that the problems of what has become a standard negative answer to the question (mainly brought forward by empiricists) become very clear in Berkeley’s case and one can also learn a lot from this.

This article analyzes the thesis of ethical relativism, as defended by Alchourrón and Bulygin. These authors offer, on the one hand, a suggestive conception according to which the question “what are our obligations?” is equivalent to thinking about what is to be done; on the other hand, they defend a relativist conception of ethics. They present three objections to constructivist accounts of ethics that are not relativist: a) the argument of the burden of the proof; b) a version of the (...) dilemma of Euthyphro, and c) the argument of particularism. This article presents counterarguments to these objections in the attempt to show that they are not conclusive and that a space therefore remains for objectivity in the normative sphere. Keywords: Alchourrón-Bulygin, ethical relativism, ethical constructivism, burden of proof, particularism. (shrink)

I argue that sounds are best conceived not as pressure waves that travel through a medium, nor as physical properties of the objects ordinarily thought to be the sources of sounds, but rather as events of a certain kind. Sounds are particular events in which a surrounding medium is disturbed or set into wavelike motion by the activities of a body or interacting bodies. This Event View of sounds provides for a uni- ?ed perceptual account of several pervasive sound phenomena, (...) including transmission through barriers, constructive and destructive interference, and echoes.

William Molyneux raised the following question: if a congenital blind person is made to see, and is visually presented with a cube and a globe, would he be able to call the shapes before him a cube and a globe before touching them? Locke, Berkeley, Leibniz, and Reid presented their phenomenological view of shape perception, i.e. their view as to what it is like to perceive shape by sight and touch, in responding to Molyneux’s Question. The four philosophers shared the (...) view that visual perception delivers no solid shape. This view would provide a premise for an argument for immaterial objects. The purpose of my thesis is to reject that argument. Kant’s view and John Campbell’s externalist account offer a way to reject the premise of the argument in question. However, my strategy is not to adopt their view. I pursue Reichenbach’s view that the there is no congruence or incongruence involved in the visual phenomenology. I develop his view, and propose the view that visual perception delivers no flat or solid shape. Although my view endorses the premise in question, I can offer a way to reject the argument. This is because my view is compatible with a form of externalism about perception (which differs from Campbell’s). My view can also do full justice to the phenomenological views presented by the four philosophers. (shrink)

The paper argues that Plato’s dialogue form creates a Quinean “opaque context” that segregates the assertions by Plato’s characters in the dialogues from both Plato and the real world with the result that the dialogues require a hermeneutical interpretation. Sec. I argues that since the assertions in the dialogues are located inside an opaque context, the forms of life of the characters in the dialogues acquires primary philosophical importance for Plato. The second section argues that the thesis of Sec. I (...) coheres with the claim in Plato’s Seventh Letter that since philosophical truth is incommunicable by means of language it is of primary importance for philosophers to develop proper “schemes of living”. Sec. III argues since the forms of life of the characters portrayed in the dialogues is of primary philosophical importance for Plato, and since hermeneutical methods are required to interpret emerging forms of life, Plato’s dialogues are positively crafted to be read hermeneutically. Sec IV argues that Heidegger, who is famous for seeing Plato’s views as antithetical to his own hermeneutical approach, is mistaken, and that Plato’s real views are, in principle, more akin to Heidegger’s views than he thinks.

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)

In this dissertation I consider the problem of external world skepticism and attempts at providing an argument to the best explanation against it. In chapter one I consider several different ways of formulating the crucial skeptical argument, settling on an argument that centers on the question of whether we're justified in believing propositions about the external world. I then consider and reject several options for getting around this issue which I take to be inadequate. I finally conclude that the best (...) option available to us at the moment is to argue that the antiskeptical view is the best explanation of our ordinary experiences In chapter two I argue that, if we hope to ground what counts as defending antiskepticism in common sense, there is an argument against the possibility of ever knowing one has succeeded in defending antiskepticism. After showing that common sense is no place to look in setting a goal for our antiskeptical project, I present the view that what will be crucial to settling on our antiskeptical goal is coming to a successful analysis of the nature of physical objects. I suggest some minimal criteria that must be met by a view in order to be antiskeptical based on our intuitions about core skeptical cases, but acknowledge that a fully successful response to external world skepticism will require the antiskeptic to engage in some much more difficult analysis. In chapter three I consider various views of the nature of explanation and conclude, tentatively, that explanation as it interests the antiskeptic is fundamentally causal. In chapter four I consider and reject some of the core views on which best explanation facts are so fundamental that a project of attempting to vindicate probabilistically the virtues which make explanations epistemically good. In this chapter I show that views which analyze justification in terms of best explanation factors fail. In chapter five I attempt to vindicate the various explanatory virtues probabilistically. In doing so I attempt to express or translate the various explanatory virtues in terms of probabilities in order to show that having those virtues makes a view at least prima facie more probable. In chapters six and seven I explain and evaluate the various arguments to the best explanation against skepticism present in current philosophical literature. I attempt to show that extant arguments fail to appreciate the virtues possessed by classical skeptical scenarios. In chapter eight I briefly consider some options that may be open to the antiskeptic moving forward. All routes forward contain considerable obstacles, but there are some fruitful areas of research to pursue. (shrink)
