  Unfortunately for the Cinematic realist, closer scrutiny reveals that each of these proposals is problematic. A moving ‘beam’ of awareness could produce a period of time during which experience is continuously occurring, in the sense that at each moment during the interval there is an experience being had by the relevant subject, but by itself it can produce nothing more, and – for a viable form of realism, at least – more is required. For a subject to be directly aware of a temporally extended phenomenon (such as a brief movement), adjoining phases of the phenomenon must in some manner be experienced together by the subject. As noted in §1.2, realists subscribe to the Diachronic Unity Thesis: they hold that contents that appear to occur in succession can be experienced together (or be co-conscious), in just the same way as contents which appear to occur simultaneously, at least within the confines of the specious present. But since for the Cinematic realist individual episodes of awareness are durationless, and likewise the contents apprehended in such episodes, it is difficult to see how the required Diachronic Unity can be accommodated. Since ex hypothesi our awareness does not extend beyond or between momentary episodes of experiencing, there is no scope at all for adjoining phases to be experienced together in the way required.
