Perspective / Peacocke: an explanation of perspective sensitivity (e.g. response to displacement of the food) - it should make clear the dependence of body movements on changes of the location - but: the subject never needs to move, it just needs to have the ability of re-centering of the intentional network.
Behavior / perspective / Peacocke: if an entity displays perspective behavior, it will be correlated not only with changing sensation qualities of his experience, but also with everything else, with which the sensation features are correlated - but it does not follow that he has attitudes about his retinal irritation - therefore we need to have access to other content, related to the retina irritation.
