||Which properties are we presented with in perception? In vision, do we consciously see just color, shape, illumination, and motion, or can we visually experience more complex properties such as kinds, causation, and personal identity? The main issue concerns how rich or impoverished perceptual contents are. This issue bears on the role of contents of perception in providing rational support for beliefs. If perceptual experiences suggest a range of propositions that are candidates for being justified by those experiences, then the propositions in this range will be influenced by the contents perception can have. Some skeptical challenges may rely on the relative impoverishment of contents. If contents can be more complex, then we can ask how perceptual experience come to have such contents, and whether other mental states besides input systems traditionally categorized as part of perception can influence perceptual contents. The issue also bears on the role perceptual experience in guiding action. Which actions an experience is poised to guide will depend on which properties that experience presents. It also raises the possibility that experiences could have imperative contents, rather than just indicative contents - a possibility explored in the philosophical literature on the pain.
