Most things we see look colored to us. But what is color? Where, if anywhere, is it? Why do we see it? When do we see it correctly? And how should we go about answering these surprisingly difficult questions? This essay surveys philosophical work on color and color perception.

What is the function of color vision? In this paper, I focus on perceptual phenomena studied in psychophysics and argue that the best explanation for these phenomena is that the color visual system is a perceptual enhancement system. I first introduce two rival conceptions of the function of color vision: that color vision aims to detect or track the fine-grained colors of distal objects and scenes (Seeing Color) and that it aims to help organisms discriminate, detect, track and/or recognize ecologically (...) important objects, properties, and relations more directly (Seeing with Color). I then discuss two kinds of systematic perceptual phenomena investigated by psychophysicists: approximate color constancy and color induction. I argue from the premise that Seeing with Color better accommodates and explains these phenomena to the conclusion that it is the conception that an empirically-guided philosopher of color ought to adopt.

I have two main goals in this paper. My first goal is to sketch a new view of color perception. The core of the view can be expressed in the following two theses: (i) the overarching function of color vision is to enable and enhance the manifestation of relevant (species-specific) competences and (ii) color experiences are correct when they result from processing that directly and non-accidentally subserves the manifestation of such competences. My second goal is to show that the view (...) can accommodate and account for a wide variety of color perceptual phenomena, including many problem cases. Importantly, the framework allows us to differentiate between two kinds of good cases of color perception: ideal cases where the demands of the relevant competences converge and non-ideal cases where the demands of the relevant competences diverge and clash.

The mainstream view in contemporary analytic philosophy is that perception is primarily in the business of representing the mind-independent world as it is. My dissertation explores an alternative conception: that the goal of perception is to guide successful action and that perceptions do not need to track mind-independent properties to play this action-guiding role. I focus on two types of perception: color perception and pain perception. I start with the former and advocate a pragmatist, empirically-guided approach which begins by inquiring (...) into the function of color vision. After arguing that none of the extant philosophical views of color are satisfactory, I answer the function question by focusing on systematic color perceptual phenomena investigated by psychophysicists. I argue that the human color visual system is an enhancement system: that is, its job is to help us better discriminate, track, and recognize meaningful objects, properties, and relations. I then build on this idea using the notion of ‘competence-embeddedness.’ I propose that color vision is embedded in a network of competences: the aim of color vision is to help organisms manifest these competences, and color experiences are correct when they result from competence-enhancing processing. The framework is explanatorily robust. For example, it allows me to conceptualize many textbook color illusions as special cases of successful color perception where the demands of the relevant competences clash. Finally, I use the notion of ‘competence-embeddedness’ to develop a new account of pain. I argue that the pain system is not a bodily disturbance detector, but a sophisticated, context-responsive security system whose primary goal is to help organisms manifest important behavioral and cognitive competences.

What is the function of pain? A popular view in contemporary philosophy is that the pain system is a bodily disturbance detector: pain states track/detect and represent bodily disturbances and the phenomenal character of the (sensory dimension of) pain supervenes on this representational content. The view can accommodate paradigmatic pain cases, e.g., when pain follows from stepping on a nail. Once we consider more complex pain phenomena, however, it has seemingly little to offer. In this paper, I discuss dissociation between (...) pains and bodily disturbances, variation in pain thresholds, the effects of repeated stimulation on experienced pain intensity, and the modulation of pain experience by cognitive and emotional states. I argue that these phenomena suggest that the pain system is not a bodily disturbance detector, but a sophisticated security system. (shrink)
