Colors are sensible qualities. They are qualities that objects are perceived to have. Thus, when Norm, a normal perceiver, perceives a blue bead, the bead is perceived have a certain quality, perceived blueness. `Quality', here, is no mere synonym for property; rather, a quality is a kind of property a qualitative, as opposed to quan• titative, property. (The quantitative is a way of contrasting with the qualitative perhaps not the only way.).

Recent philosophy has seen a resurgence of the realist view of sensible qualities such as colour. The view holds that experienced qualities are properties of the objects in the physical environment, not mentally instantiated properties like qualia or merely intentional, illusory ones. Some suggest that this move rids us of the explanatory gap between physical properties and the qualitative features of consciousness. Others say it just relocates the problem of qualities to physical objects in the environment, given that such qualities (...) cannot be derived from the non-qualitative properties of objects, and it does not resolve the problem of consciousness either. I argue that such an outcome is welcome: if the physical world is full of explanatory gaps, then the mind–body explanatory gap is not so special. Moreover, the explanatory gaps regarding qualities of objects are less puzzling than the brain-qualia gap. In order to counter the usual worries concerning realism about objective qualities, I introduce ‘imperfect realism’ as an alternative to colour pluralism and complex reductionism, which accommodates realism in the face of widespread perceptual error. I conclude with a discussion of how this ‘multiple-gaps view’ sits better with a naturalistic framework compared to the Galilean-Cartesian account of qualities. (shrink)

This paper presents a new response to the colour similarity argument, an argument that many people take to pose the greatest threat to colour physicalism. The colour similarity argument assumes that if colour physicalism is true, then colour similarities should be scrutable under standard physical descriptions of surface reflectance properties such as their spectral reflectance curves. Given this assumption, our evident failure to find such similarities at the reducing level seemingly proves fatal to colour physicalism. I argue that we should (...) dispense with this assumption, and thus endorse the inscrutability of colour similarity. This strategy is inspired by parallels between the colour similarity argument and the explanatory gap between mind and body made vivid by Jackson’s (1986) knowledge argument, and in particular by type-B physicalist responses to that argument. This inscrutability response is further motivated by cases in chemistry and biochemistry in which analogous scrutability theses fail to hold. Along the way, I present a challenge to standard formulations of the colour similarity argument based on the extreme context sensitivity of the similarity relation. Most presentations of the argument fail to control for such contextual variation, which raises the distinct possibility that the argument equivocates on the similarity relation across its premises. Although ultimately inconclusive, this context challenge forces a significant reformulation of the colour similarity argument, and highlights the need for much greater care in handling claims about colour similarity.

According to a familiar modern view, color and other so-called secondary qualities reside only in consciousness, not in the external physical world. Many have argued that this “Galilean” view is the source of the mind-body problem in its current form. This paper critically examines a radical alternative to the Galilean view, which has recently been defended or sympathetically discussed by several philosophers, a view I call “anti-modernism.” Anti-modernism holds, roughly, that the modern Galilean scientific image is incomplete – in particular, (...) it leaves out certain irreducible qualitative properties, such as colors – and that we can solve (or dissolve) the hard problem of consciousness by accepting these properties as objective features of the external physical world. I argue, first, that anti-modernism cannot fulfill its promise. Even if the outer world is resplendent with primitive colors, color experience remains a mystery. Second, I argue that the theoretical costs of accepting irreducible colors in the world are enormous. Even if irreducible colors in the world could dispel the mysteries surrounding consciousness, the theoretical benefit would not be worth the cost. If the problems of consciousness and color require that we posit irreducible properties somewhere, it would be far more plausible to accept irreducible phenomenal properties on the side of the subject, and to reject irreducible colors on the side of the object.
