 We can think about the content of perception in conceptual terms. When someone has a visual experience, for example, it will seem to that person as if something is seen. One way of specifying the way things appear to the subject is in terms of the perceptual belief the subject would form on the basis of perception had he taken his perception at face value. Such a way of specifying the representational content of perception gives us the propositional content of perception. Theorists of nonconceptual content have canvassed several types of reasons for thinking that this propositional content does not exhaust the representational content of perception (see the entry on  the contents of perception).[6]
