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.

Feldman proposed a solution to the speckled hen problem via ‘phenomenal concepts’, a solution which Fumerton accepted with reservation. Notwithstanding the existing criticisms of Feldman as being over-intellectualist, I argue that his approach fails for other reasons.

There seem to be some misunderstandings abroad in the literature about medical epistemology and person-centered medicine concerning the nature of 'modest' or aetiological foundationalism, and some vagueness about 'emergence'. This paper urges a greater tolerance for a modest, Humean variety of foundationalism, not least because it seems to offer significant support for person-centred medicine. It also suggests a closer examination of emergence as an explanation or justification for medicine, since emergence is a complex concept that does nothing to rule out (...) foundationalism. Foundationalism has been condemned tout court without recognizing that it comes in various styles and degrees. Emergence has been used as a property of medicine to dismiss any need to seek its foundations. But emergence too comes in different forms, not all of them at odds with modest foundationalism. Modest or aetiological foundationalism is far more flexible than Cartesian foundationalism, and is compatible with modern understandings of emergence. Modest foundationalism and a particular understanding of emergence support the ontological and epistemological underpinning of person-centered medicine. (shrink)

One important strand of Sellars’s attack on classical foundationalism from Empiricism and the Philosophy of Mind is his thesis about the priority of is-talk over looks-talk. This thesis has been criticized extensively in recent years, and classical foundationalism has found several contemporary defenders. I revisit Sellars’s thesis and argue that is-talk is epistemically prior to looks-talk in a way that undermines classical foundationalism. The classical foundationalist claims that epistemic foundations are constituted by the agent’s set of looks-judgments. However, I argue (...) that only a subset of these looks-judgments are even candidates to serve as foundations for the agent’s empirical knowledge, and membership in this subset is determined by the agent’s theory of how the world is. Thus, the epistemic force of the looks-judgments in this subset is dependent on the agent’s theory of how the world is. This means that these looks-judgments aren’t foundational at all, as the agent’s theory of how the world is is epistemically is prior to the epistemic status of these looks-judgments. This is the sense in which judgments about how the world is are epistemically prior to judgments about how things look. This conclusion allows concrete elaboration of another of Sellars’s well-know claims: “I do wish to insist that the metaphor of ‘foundation’ is misleading in that it keeps us from seeing that if there is a logical dimension in which other empirical propositions rest on observation reports, there is another logical dimension in which the latter rest on the former”.

In this paper I argue that there is no viable alternative to construing our knowledge and justified belief as resting on a foundation restricted to truths about our internal states. Against Williamson and others I defend the claim that the internal life of a cognizer really does constitute a special sort of cognitive home that is importantly different from the rest of what we think we know and justifiably believe.

When contemporary philosophers discuss the nature of knowledge, or conduct debates that the nature of knowledge is relevant to, they typically treat all knowledge as propositional. However, recent introductory epistemology texts and encyclopedia entries often mention three kinds of knowledge: (i) propositional knowledge, (ii) abilities knowledge, and (iii) knowledge of things/by acquaintance. This incongruity is striking for a number of reasons, one of which is that what kinds of knowledge there are is relevant to various debates in philosophy. In this (...) paper I focus on this point as it relates to the third kind of knowledge mentioned above – knowledge of things. I start by supposing that we have knowledge of things, and then I show how this supposition reshapes various debates in philosophy. (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.

Our beliefs utilize various sources: perception, memory, induction, etc. We trust these sources to provide reliable information about the world around us. My dissertation investigates how this trust could be justified. Chapter one introduces background material. I argue that justification rather than knowledge is of primary epistemological importance, discuss the internalism/externalism debate, and introduce an evidentialist thesis that provides a starting point/framework for epistemological theorizing. Chapter two introduces a puzzle concerning justification. Can a belief source provide justification absent prior justification (...) for believing it's reliable? Any answer appears to either make justifying the reliability of a source intellectually unsatisfying or all together impossible. Chapter three considers and rejects a plethora of proposed solutions to our puzzle. Investigating these solutions illustrates the need to further investigate evidence, evidence possession, and evidential support. Chapter four discusses the metaphysics of evidence. I argue that evidence always consists of a set of facts and that fact-proposition pairs stand in confirmation relations isomorphic to those holding between pairs of propositions. Chapter five argues that justification requires what I call actually connected possession of supporting evidence: a subject must be aware of supporting evidence and of the support relation itself. Chapter six argues that the relation constitutive of a set of facts being justificatory evidence is a sui generis and irreducible relation that is knowable a priori. Chapter seven begins by showing how Richard Fumerton's acquaintance theory meets the constraints on a theory of justification laid down in previous chapters. I modify the theory so as to: make room for fallible foundational justification, and allow inferential justification absent higher-order beliefs about evidential connections. Chapter eight applies the developed theory of justification to our initial puzzle. I show how my modified acquaintance theory is in a unique position to vindicate the idea that necessarily a source provides a person with justification only if she is aware of evidence for the reliability of that source. However, this awareness of evidence for a source's reliability falls short of a justified belief and thereby avoids impalement from our dilemma's skeptical horn. (shrink)

This dissertation defends the reliability of first-person methods for studying consciousness, and applies first-person experiments to two philosophical problems: the experience of size and of the self. In chapter 1, I discuss the motivations for taking a first-person approach to consciousness, the background assumptions of the dissertation and some methodological preliminaries. In chapter 2, I address the claim that phenomenal judgements are far less reliable than perceptual judgements (Schwitzgebel, 2011). I argue that the main errors and limitations in making phenomenal (...) judgements are due to domain-general factors, which are shared in the formation of perceptual judgements. Phenomenal judgements may still be statistically less reliable than perceptual judgements, though I provide reasons for thinking that Schwitzgebel (2011) overstates the case for statistical unreliability. I also provide criteria for distinguishing between reliable and unreliable phenomenal judgements, hence defending phenomenal judgements against general introspective scepticism. Having identified the main errors in making phenomenal judgements, in chapter 3, I discuss how first-person experiments can be used to control for these errors. I provide examples, and discuss how they overcome attentional and conceptual errors, minimise biases, and exhibit high intersubjective reliability. In chapter 4, I investigate size experience. I use first-person experiments and empirical findings to argue that distant things looking smaller cannot be explained as an awareness of instantiated objective properties (visual angle or retinal image size). I also discuss how an awareness of uninstantiated objective properties cannot adequately account for the phenomenal character of size experience. This provides support for a subjectivist account of variance in size experience. In chapter 5, I investigate the sense of self. I distinguish between a weak sense of self (for-me-ness) and a strong sense of self in which there is a polarity between subject and object. I use first-person experiments from Douglas Harding to demonstrate an explicit strong sense of self, specifically when I point at where others see my face. I also argue that this sense of self is not explained by inference, thoughts, feelings, imagination nor the viewpoint. Rather, it is part of the structure of experience that I seem to be looking from here. Even if there is a sense of self, there may be no self. The question of chapter 6 is whether there can be a direct experience of the self. I argue that to function as a bearer of experience the subject must be single and lack sensory qualities in itself. I use Harding’s first-person experiments to investigate the visual gap where I cannot see my head. I argue that it conforms to the above criteria, and hence is a candidate for being the subject. This finding, in conjunction with the fact that I seem to be looking from the same location, provides prima facie evidence for the reality of the subject. I hold then that contrary to Hume and most philosophers since, that there can be a direct self-experience, if one knows which direction to attend. (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)

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)
