 How is unified conscious experience structured? As we mentioned in  Section 2.1,  two incompatible models have some currency at the moment. On the experiential parts view (EP), unified conscious experience includes simpler experiences as parts or something like parts; unified consciousness has a mereological aspect. On this view, when I have a unified experience of a pain and a noise, this unified experience includes an experience of just the pain, and an experience of just the noise. These simpler experiences are the relata of unified consciousness; they are joined as parts of the unified experience of the pain and noise together. Experiences a and b are united in a third experience, c, which is their joint occurrence. On the no experiential parts (NEP) account, the conscious mental act through which diverse contents are presented does not have other conscious states, experiences, as parts. On the first view, when I have unified consciousness of experiencing, I am conscious of many experiences. On the second view, I am conscious of just one experience.
