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.

Conceptual engineering is often understood as the practice of assessing and improving our representational tools with specific aims in mind. In this paper, I contribute to the engineering of the concept of pain with a particular focus on clinical utility. My engineering efforts center on the International Association for the Study of Pain’s (IASP) “official” definition of pain, first introduced in 1979 and revised in 2020. I discuss the general process of conceptual engineering and the original IASP definition of pain and identify three desiderata for a definition suitable for clinical practice: it should be accurate, cognitively tractable, and promote justice in patient care. Evaluating the revised IASP definition against these desiderata, I argue that it is vague and fails to fully address persistent misconceptions about pain, and that additional revisions are therefore needed. I then propose an alternative definition engineered to better meet the demands of effective and just clinical practice.

Healthcare providers often rely on the following sort of concerning reasoning when encountering patients with difficult-to-explain symptoms: in the absence of evidence for a physical cause, the symptoms are presumed to be psychological in origin. In this paper, we take up this concern in the context of chronic pain, with particular attention to how such reasoning disproportionately affects women and how it interacts with the many levels of gender bias in medicine. We first examine the unwarranted inference from diagnostic uncertainty to psychogenic diagnosis and explore how identity prejudice and diagnostic uncertainty interact in clinical practice. We then consider additional contributors to diagnostic uncertainty concerning women’s pain: gendered research gaps and male-centered diagnostic paradigms. After outlining the harms associated with psychogenic diagnoses, we consider the objection that such diagnoses might be pragmatically justified. We end by calling for a more nuanced approach to diagnosing and treating chronic pain.

Most of us have experienced some, probably many, forms of bodily pain. Unless you were born with congenital insensitivity to pain, you’ve likely experienced at least toothaches, headaches, or backaches. Pain experiences differ in intensity, quality, and duration. A toothache might be sharp and intense but fleeting, while a backache might be dull and aching yet more enduring. Despite these differences, there seems to be a common thread that unites toothaches, backaches, and so on—something that makes them all pains. This raises interesting philosophical questions: is pain physical or mental? What is the role of the pain system? And, is pain always unpleasant? These questions are the focus of this essay.

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 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.
