Knowledge of Color As colors have a metaphysics, so they have an epistemology. In addition to ordinary empirical truths about what colors objects have, there are also general truths stating a priori necessities: for example, “Orange is closer to red than to blue”, “There cannot be reddish green”, “Nothing can be white […]
Colors and Powers Again Locke distinguishes primary qualities from powers to produce sense impressions of them in perceivers, but he thinks that secondary qualities are “nothing else, but several powers in them, depending on these primary qualities…to produce several different ideas in us”. [1] That is, he identifies colors with powers to produce […]
Colors and Powers According to Locke, colors are nothing but powers in objects to produce ideas in our minds. He writes: “What I have said concerning colours and smells, may be understood also of tastes, and sounds, and other the like sensible qualities; which, whatever reality we by mistake, attribute […]
Color and Causality Color and causality don’t mix: causality doesn’t mention color and color is indifferent to causality. Shape is very different: shape always affects causal powers. Shape and causality are made for each other, while color and causality are complete strangers. This means that ordinary objects have two aspects—causal and non-causal. […]
Color and Perception For color, to be is to be perceived: not so for shape. That was a central tenet of the modern philosophers. Color depends on perceivers for its existence, but shape does not. Thus it makes no sense to suppose that colors exist in a possible world and yet no […]
Object Mentalism and Philosophy What impact would the truth of object mentalism have on the philosophical landscape? For expository reasons I shall speak as if it is true, though we could also conjure a possible world in which it is stipulated to be true and consider philosophy as it exists in that world. […]
Earth Mind Let’s suppose that object mentalism is true—the doctrine that every object has a mental life. I mean this doctrine as derived from the thesis that all secondary qualities need a psychological subject: since such qualities are mental they must be perceived, so everything having them is a perceiver of some sort. [1] […]
Secondary Qualities and Possible Worlds Consider a possible world in which all objects have minds, indeed selves: every physical object is a subject of consciousness. In this world every object has a brain, though the brains might not be very like the brains we are familiar with. Thus trees, rivers, mountains, post boxes, […]
Color and Object I am going to give a list of reasons for supposing (a) that colors are mental and (b) that colors are in external objects. None of them is apodictic but they provide a powerful prima facie case, which I think is supported by common sense. As to (a) […]
Mind in World I am going to describe a chain of reasoning that begins with commonsense premises and ends with a startling conclusion. It is prompted by some remarks of Berkeley concerning the instantiation of mental properties: “Now for an idea to exist in an unperceiving thing, is a manifest contradiction; for […]
