||What kinds of information is conveyed to a subject by her conscious perceptions? Suppose you are looking into a piano at the array of hammers and strings. There will be a way these things look to you when you see them: they will look to have a certain shape, color, texture, and arrangement relative to one another, among other things. Your visual experience conveys to you that the piano has these features. If your experience is illusory in some respect then the piano won't really have all those features; but even then, there will still be something conveyed to you by your experience. Issues in this category include: what are contents and what is their relation to experiences? Which contents are contents of experience? In virtue of what do experiences have contents, when they do? What is the role of the particular objects we see in the contents of experience? What is the role of properties in the contents of experience? What is the role of concepts in determining which experiences we have, and which contents they have?
