"Image and Content in Sensory Representation"

Sensory states express their representational content through images. Images cannot express tense, place-relative-to-the-observer, or factiveness. This creates a puzzle. Memory, fantasy, pictorial vision, and sense perception can be directed towards similar images. Yet they are different in precisely the respects that images cannot express: the image in memory is past tensed, unlocated relative to the observer, and factive; in sense-perception, it is present tensed, located relative to the observer, and factive; in pictorial vision, it is unlocated relative to the observer, untensed, and non-factive. How are these semantically significant differences expressed? Here the distinction between content (the situation expressed by the image) and force of expression (how the subject means that situation to be expressed) is relevant, as the same image could be meant with different force. But how does a sensory system express a force operator? The paper deals with the problem and a solution.
