 Many theorists have also had a fourth thing in mind when they speak of the unity of consciousness, namely, unified consciousness of oneself, the thing that has the experiences. Here, one is or certainly seems to be (see the discussion of Rosenthal in  Section 3.1)  conscious of oneself not just as subject but, in Kant’s words (A350), as the ‘single common subject’ of many or all the aspects of the unified experience that one is now having and of a number of similar experiences past and, in anticipation, still to come. (Mutatis mutandis, the same holds for the single common agent of various bits of deliberation and action.) One has unified consciousness of self when one is conscious of oneself as the single common subject of experiences of many items in many acts of experiencing.
