Are colors relational or non-relational properties of their bearers? Is red a property that is instantiated by all and only the objects with a certain intrinsic (/non-relational) nature? Or does an object with a particular intrinsic (/non-relational) nature count as red only in virtue of standing in certain relations - for example, only when it looks a certain way to a certain perceiver, or only in certain circumstances of observation? In this paper I shall argue for the view that color properties are relational (henceforth, relationalism), and against the view that colors are not relational (henceforth, anti- or non-relationalism)

According to many philosophers, psychological explanation canlegitimately be given in terms of belief and desire, but not in termsof knowledge. To explain why someone does what they do (so the common wisdom holds) you can appeal to what they think or what they want, but not what they know. Timothy Williamson has recently argued against this view. Knowledge, Williamson insists, plays an essential role in ordinary psychological explanation.Williamson's argument works on two fronts.First, he argues against the claim that, unlike knowledge, belief is``composite'' (representable as a conjunction of a narrow and a broadcondition). Belief's failure to be composite, Williamson thinks, undermines the usual motivations for psychological explanation in terms of belief rather than knowledge.Unfortunately, we claim, the motivations Williamson argues against donot depend on the claim that belief is composite, so what he saysleaves the case for a psychology of belief unscathed.Second, Williamson argues that knowledge can sometimes provide abetter explanation of action than belief can.We argue that, in the cases considered, explanations that cite beliefs(but not knowledge) are no less successful than explanations that citeknowledge. Thus, we conclude that Williamson's arguments fail both coming andgoing: they fail to undermine a psychology of belief, and they fail tomotivate a psychology of knowledge.

No one disputes that certain cognitive tasks involve the use of images. On the other hand, there has been substantial disagreement over whether the representations in which imaginal tasks are carried out are imaginal or propositional. The empirical literature on the topic which has accrued over the last twenty years suggests that there is a functional equivalence between mental imagery and perception: when peopIe imagine a scene or event, the mental processes that occur are functionally similar in important senses to what happens when they visually perceive an analogous scene or event. What is in dispute is not this principle of equivalence, but rather what conclusions should be drawn from it about the representational medium used in imagery.The problem to be explained is what internal cognitive events transpire when people answer questions like “What color is a bee’s head?” Most people report that they imagine a picture of the insect and then look at the head in the image to determine its color. Although there is no more reason to accept these introspective reports as a good account of cognitive processes than in any other cognitive phenomena, there are many empirical results which lend credence to the idea that there are mental images of some kind.Some theorists have taken the empirical results as evidence that there exists a special, non-symbolic representational medium for imagery. Others have insisted that the imagery data can be explained best in terms of the more general, symbolic representations which are usually taken to underly higher level cognitive tasks. In this paper I shall evaluate the arguments for both imaginal and propositional representations in the hope of assessing the status of the imagery debate. I shall conclude that imaginal theories represent the most reasonable account of imagery.

In Clark (2000), Austen Clark argues convincingly that a widespread view of perception as a complicated kind of feature-extraction is incomplete. He argues that perception has another crucial representational ingredient: it must also involve the representation of "sensory individuals" that exemplify sensorily extracted features. Moreover, he contends, the best way of understanding sensory individuals takes them to be places in space surrounding the perceiver. In this paper, I'll agree with Clark's case for sensory individuals (

Philosophy of mind today is a sprawling behemoth whose tentacles reach into virtually every area of philosophy, as well as many subjects outside of philosophy. Of course, none of us would have it any other way. Nonetheless, this state of affairs poses obvious organizational challenges for anthology editors. Brian McLaughlin and I have attempted to meet these challenges in the present volume by focusing on ten controversial and fundamental topics in philosophy of mind. ‘Controversial’ is clear enough: we have chosen topics about which there is not a settled consensus among philosophers. By ‘fundamental’, we don’t mean that the issues are easy or that the approaches taken toward them are introductory. Rather, we mean that (i) the resolution of these topics has implications for other issues inside and outside philosophy of mind, and (ii) past rounds of debate have revealed these topics as underlying broader disagreements. We asked leading philosophers of mind to defend one side or another on these topics. The result is what you now have in your hands.

In The Quest for Reality: Subjectivism and the Metaphysics of Colour [Stroud, 2000], Barry Stroud carries out an ambitious attack on various forms of irrealism and subjectivism about color. The views he targets - those that would deny a place in objective reality to the colors - have a venerable history in philosophy. Versions of them have been defended by Galileo, Descartes, Boyle, Locke, and Hume; more recently, forms of these positions have been articulated by Williams, Smart, Mackie, Ryle, and Hardin, among others. Stroud's aim is to argue not only that these writers fail to make their cases, but that no conceivable argument could ever convince us that colors are not a part of objective reality.

In “The Location Problem for Color Subjectivism,” Peter Ross argues against what he calls subjectivism — the view that “colors are not describable in physical terms,... [but are] mental processes or events of visual states” (2), 1 and in favor of physicalism — a view according to which colors are “physical properties of physical objects, such as reflectance properties” (10). He rejects an argument that has been offered in support of subjectivism, and argues that, since no form of subjectivism is able to account for our perception of color, we are better off adopting physicalism.
