out, change some aspects, and so on. For instance, imagine an unsymmetrical shape, such as a Swiss Army knife with several of its attachments extended—say a scissors pointing leftward, a bottle opener extended upward, a knife blade downward. One can mentally recreate how this would look if rotated: where the three instruments would point, how the foreshortening would change, how the protrusions would recede and approach relative to one another, and so on. Like the alternation between field and observer perspectives, this indicates that the underlying mental images do not themselves encode observer perspectives. They are stored in memory; and perspective-dependent views are constructed from them on the fly. But they are always presented from a perspective when they are entertained. When these scenes are mentally entertained, they yield what Christopher Peacocke (1983) has called a scenario, which consists of a point-of-view, and featured things with sensory qualities at locations specified relative to this point of view. (Perceivable things are an addition to scenarios as Peacocke envisaged them.)
