" The new internal world is a world dominated by the body frame, by the location and state of the sensory portals within that frame, and by the voluntary musculature. The sensory portals sit and wait within the body frame and contribute importantly to the information generated by the maps of the outside world. They clearly indicate to the organism’s mind the locations, within the organism, of the sources of images currently being generated. This is necessary for the construction of an overall organism image, which, as we shall see, is a critical step in the generation of subjectivity. "
