It is a common assumption among philosophers of perception that phenomenal colors are exhaustively characterized by the three phenomenal dimensions of the color solid: hue, saturation and lightness. The hue of a color is its redness, blueness or yellowness, etc. The saturation of a color refers to the strength of its hue in relation to gray. The lightness of a color determines its relation to black and white. In this paper, I argue that the phenomenology of shadows forces us to (...) consider illumination as an additional dimension of phenomenal colors. For this purpose, I will first introduce two different interpretations of shadow-experiences, which Chalmers has called the simple and the complex interpretations, and show that they both fail to account for important phenomenal facts about shadow-experiences. I will then introduce my own alternative interpretation based on the idea that illumination is a dimension of phenomenal colors and explain how it can account for these facts. (shrink)

A central question, if not the central question, of philosophy of perception is whether sensory states have a nature similar to thoughts about the world, whether they are essentially representational. According to the content view, at least some of our sensory states are, at their core, representations with contents that are either accurate or inaccurate. Tyler Burge’s Origins of Objectivity is the most sustained and sophisticated defense of the content view to date. His defense of the view is problematic in (...) several ways. The most significant problem is that his approach does not sit well with mainstream perceptual psychology. (shrink)

The dominant view among philosophers of perception is that color experiences, like color judgments, are essentially representational: as part of their very nature color experiences possess representational contents which are either accurate or inaccurate. My starting point in assessing this view is Sydney Shoemaker’s familiar account of color perception. After providing a sympathetic reconstruction of his account, I show how plausible assumptions at the heart of Shoemaker’s theory make trouble for his claim that color experiences represent the colors of things. (...) I consider various ways of trying to avoid the objection, and find all of the responses wanting. My conclusion is that we have reason to be skeptical of the orthodox view that color experiences are constitutively representational. (shrink)

We present select examples of how visual phenomena can serve as tools to uncoverbrain mechanisms. Specifically, receptive field organization is proposed as a Gestalt-like neural mechanism of perceptual organization. Appropriate phenomena, such as brightness and orientation contrast, subjective contours, filling-in, and aperture-viewed motion, allow for a quantitative comparison between receptive fields and their psychophysical counterparts, perceptive fields. Phenomenology might thus be extended from the study of perceptual qualities to their transphenomenal substrates, including memory functions. In conclusion, classic issues of Gestalt (...) psychology can now be related to modern. (shrink)
