Abstract

What is the relation between a perceptual experience of an object X as being red, and one's belief, if any, as to the nature of that experience? A traditional Cartesian view would be that, if indeed object X does seem to be red to oneself, then one's resulting introspective belief about it could only be a _conforming _belief, i.e., a belief that X perceptually seems to be _red _to oneself--rather than, for instance, a belief that X perceptually seems to be green to oneself instead. On such a Cartesian view, our introspective certainly about our own thoughts extends also to our perceptual experiences as to how things seem to be to us, so that our resulting introspective beliefs about our phenomenal states also count as knowledge of them.
