Suppose you're unable to discriminate the colors of two objects. According to the triangulation view, their colors might nonetheless look different to you, and that's something you can discover as a result of further comparisons. The primary motivation for this view is its apparent ability to solve a puzzle involving a series of pairwise indiscriminable objects. I argue that, due to visual noise, the triangulation view doesn't really solve the puzzle.

I motivate and defend a previously underdeveloped functionalist account of the metaphysics of color, a view that I call ‘quality-space functionalism’ about color. Although other theorists have proposed varieties of color functionalism, this view differs from such accounts insofar as it identifies and individuates colors by their relative locations within a particular kind of so-called ‘quality space’ that reflects creatures’ capacities to discriminate visually among stimuli. My arguments for this view of color are abductive: I propose that quality-space functionalism best (...) captures our commonsense conception of color, fits with many experimental findings, coheres with the phenomenology of color experience, and avoids many issues for standard theories of color such as color physicalism and color relationalism.

Suppose that, while you are dreamlessly asleep, the sizes of and distances between all objects in the world are uniformly multiplied. Would you be able to detect this global inflation? Intuitively, no. But would your experience of size remain accurate? Intuitively, yes. On these grounds, some have concluded that our experiences do not represent size and instead represent modes of presentation of size. We are, in this sense, ‘cut off’ from the sizes of things in the external world. Here, I (...) argue for a more modest conclusion: undetectable inflation reveals that our experiences represent only relative size. Call this view austere phenomenal relativism––or austere relativism, for short. I develop a framework to contrast austere relativism with its competitors, give an extended argument for the view, and then defuse a potential dilemma concerning the units in which our experiences represent size.

The orthodox monadic determination thesis holds that we represent colour relations by virtue of representing colours. Against this orthodoxy, I argue that it is possible to represent colour relations without representing any colours. I present a model of iconic perceptual content that allows for such primitive relational colour representation, and provide four empirical arguments in its support. I close by surveying alternative views of the relationship between monadic and relational colour representation.

Are color adjectives ("red", "green", etc.) relative adjectives or absolute adjectives? Existing theories of the meaning of color adjectives attempt to answer that question using informal ("armchair") judgments. The informal judgments of theorists conflict: it has been proposed that color adjectives are absolute with standards anchored at the minimum degree on the scale, that they are absolute but have near-midpoint standards, and that they are relative. In this paper we report two experiments, one based on entailment patterns and one based (...) on presupposition accommodation, that investigate the meaning of scalar adjectives. We find evidence confirming the existence of subgroups of the population who operate with different standards for color adjectives. The evidence of interpersonal variation in where standards are located on the relevant scale and how those standards can be adjusted indicates that the existing theories of the meaning of color adjectives are at best only partially correct. We also find evidence that paradigmatic relative adjectives ("tall", "wide") behave in ways that are not predicted by the standard theory of scalar adjectives. We discuss several different possible explanations for this unexpected behavior. We conclude by discussing the relevance of our findings for philosophical debates about the nature and extent of semantically encoded context sensitivity in which color adjectives have played a key role.

Imagine that the person you see through the looking glass is a real person, with her own experiences, living in an environment that is the mirror-reverse of yours. You look at your right-hand glove as you put it on your right hand; she looks at her left-hand glove as she puts it on her left hand. You feel your heart beating on your left side; she feels her heart beating on her right side. You hear a bird chirping out the (...) window to your left; she hears a bird chirping out the window to her right. Is there any difference between your experience—your what-it-is-like phenomenal character—and hers? She is looking at her left-hand glove, the mirror-reverse of you as you look at your right-hand glove. Does she see what you see, a right-hand glove, or the reverse of what you see, a left-hand glove? Since her environment is the mirror-reverse of yours, and she seems to get by in it just fine, you'd probably assume, if you had to guess, that she sees it correctly. She is looking at her left-hand glove, after all. So it stands to reason that she is having an experience as of a left-hand glove, not a right-hand glove. And it stands to reason—it seems obvious—that an experience as of a left-hand glove differs in what it is like from an experience as of a right-hand glove. In this paper, I will argue that this last presupposition, obvious though it may seem, is false. I'll argue that (unless dualism is true) there is no intrinsic difference between what it is like to experience a left-hand glove and what it is like to experience a right-hand glove: if there are any relevant experiential differences, these are either merely comparative (differences in what it is like to compare gloves) or cognitive (differences in what it is like to bring an experience of a glove under a concept like LEFT or RIGHT). So your mirror-reverse twin, who won't differ from you in what she is comparing or thinking, will have the same (type of) experience as you. I'll call the position I am arguing against orientation–experience categoricalism, and the position I am arguing for orientation–experience relationism. Orientation–experience relationism is a surprising thesis, one whose falsity you might take for granted. I will argue for it by cases. Things go wrong for the orientation–experience categoricalist in one sort of way if we imagine that you and your mirror-twin's experiences differ: basically, this leads to absurdity if we imagine that you and she both live at a world with a non-orientable spatial topology (in the sense in which a Möbius strip or Klein bottle are non-orientable). Things go wrong for the orientation–experience categoricalist in a different sort of way if we assume that you and your twin would experience the same, but that someone else might have the experience that we were just imagining that your twin might have. Under these assumptions, we have to accept the existence of partial zombies, who lack the relevant phenomenology but behave as if they have it, at very close, empirically possible worlds. In an appendix, I argue that property dualism is the best alternative for those who cannot bring themselves to accept orientation-experience relationism. (shrink)

Argues for a failure of correspondence between perceptual representation and what it is like to perceive. If what it is like to perceive is grounded in perceptual representation, then, using considerations of veridical representation, we can show that inattentive peripheral perception is less representationally precise than attentive foveal perception. However, there is empirical evidence to the contrary. The conclusion is that perceptual representation cannot ground what it is like to perceive.
