I argue that phenomenal externalism is preferable to phenomenal internalism on the basis of externalism's explanatory power with respect to qualitative character. I argue that external qualities, namely, external physical properties that are qualitative independent of consciousness, are necessary to explain qualitative character, and that phenomenal externalism is best understood as accepting external qualities while phenomenal internalism is best understood as rejecting them. I build support for the claim that external qualities are necessary to explain qualitative character on the basis (...) of a model of color perception as a certain sort of information filter by which perceivers gain access to external qualities.

I propose a description of one aspect of the philosophical problem about the ontology of colors by formulating and motivating six plausible premises that seem to be hard to deny in isolation but that are jointly incoherent. I briefly sketch a solution and comment on the views presented in this volume from the perspective of the puzzle.

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.

Farben sind für uns sowohl objektive, als auch phänomenale Eigenschaften. In seinem Buch argumentiert Fabian Dorsch, daß keine ontologische Theorie der Farben diesen beiden Seiten unseres Farbbegriffes gerecht werden k ann. Statt dessen sollten wir akzeptieren, daß letzterer sich auf zwei verschiedene Arten von Eigenschaften bezieht: die repräsentierten Reflektanzeigenschaften von Gegenständen und die qualitativen Eigenschaften unserer Farbwahrnehmungen, die als sinnliche Gegebenheitsweisen ersterer fungieren. Die Natur der Farben gibt einen detaillierten Überblick über die zeitgenössischen philosophischen und naturwissenschaftlichen Theorien der Farben und (...) bietet sich aufgrund seines systematischen und umfassenden Charakters auch als ein seminar- oder vorlesungsbegleitendes Textbuch an.

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

Chapter 1 is devoted to taking care of some preliminary issues. I begin by distinguishing those states of awareness in virtue of which we’re acquainted with the phenomenal characters of our experiences from those states of awareness some claim are at the very nature of experience. Then I reconcile the idea that experience is transparent with the claim that we can be acquainted with phenomenal character. -/- In Chapter 2 I set up a dilemma that is the primary focus of (...) the dissertation. In the first part of this chapter I argue that phenomenal acquaintance has three key features, what I call its ‘directness’, ‘thickness’, and ‘infallibility’. In the second part I argue, however, that it’s really quite puzzling how thoughts about phenomenal character (or any thoughts, for that matter) could have them. In the next two chapters I consider how we might resolve the dilemma described above. -/- I begin in Chapter 3 by considering an account of phenomenal acquaintance inspired by Bertrand Russell’s discussion of acquaintance. The general idea here is to excise mental representation from phenomenal acquaintance, and I ultimately reject the proposal. -/- Chapter 4 is the core chapter of the dissertation. In it I propose an account of phenomenal acquaintance that doesn’t excise mental representation. My account is comprised of three theses. First, token experiences are complex and have instances of phenomenal properties as components. Second, instances of phenomenal properties are mental representations, and they represent themselves. Third, the attention relevant to phenomenal acquaintance is underwritten by self-representation. I argue that my account explains how phenomenal acquaintance is direct, thick, and infallible, thereby resolving our dilemma. -/- I argue in Chapter 5 that my account of phenomenal acquaintance explains why there is an explanatory gap between the phenomenal and non-phenomenal truths. Accordingly, I conclude that the explanatory gap doesn’t pose a problem for physicalism. Here I implement what has come to be called the ‘phenomenal concept strategy’ for responding to the challenge posed by the explanatory gap. (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)

I advance an account of quantitative character, a species of phenomenal character that presents as an intensity (cf. a quality) and includes experience dimensions such as loudness, pain intensity, and visual pop-out. I employ psychological and neuroscientific evidence to demonstrate that quantitative characters are best explained by attentional processing, and hence that they do not represent external qualities. Nonetheless, the proposed account of quantitative character is conceived as a compliment to the reductive intentionalist strategy toward qualitative states; I argue that (...) an account of perceptual experience that combines a tracking account of qualitative character with my functionalist proposal for quantitative character permits replies to some notoriously difficult problems for tracking representationalism without sacrificing its chief virtues.

Timothy Williamson’s Knowledge and its Limits has been highly influential since the beginning of this century. It can be read as a systematic response to scepticism. One of the most important notions in this response is the notion of «evidence,» which will be the focus of the present paper. I attempt to show primarily two things. First, the notion of evidence invoked by Williamson does not address the sceptical worry: he stipulates an objective notion of evidence, but this begs the (...) question against his opponent. Second, his related thesis «Evidence equals Knowledge» does not sit well with his own content externalism: he promises to relate epistemology to philosophy of mind, but he fails to live up to this commitment in his crucial chapter on scepticism. Other minor problems concerning evidence will also be discussed in due course. (shrink)
