 This endeavor to see the total manifold of contents as a single mental event is meant as a direct way of dispelling the premises of ordinary “deluded” experience. For our ordinary experience is, we may say, premised on a mistaken application of categories derived from a conception of durational mental and physical objects to fleeting experienced moments themselves, the latter being on this view the real contents of all experience. To be more precise, it must be noted that categories such as “same” and “different,” and “whole” and “part,” and “necessary” and “contingent,” and “actual” and “possible,” and “essential properties” and “accidental properties,” actually apply only to durational objects, whether physical or mental. All of these categories require the comparison of one entity with another, which cannot be done in the span of an instantaneous upsurge of undivided experience.
