This is an excerpt about split brain patients:

The Split brain

"Recognizing that the disconnected RH is conscious provides additional evidence that language is not necessary for human consciousness. More important, using the split brain as a model for the normal mind, a normal individual's consciousness can then be viewed as the net result of an interaction among at least two distinct states of consciousness. The question then arises why the normal person with an intact brain experiences consciousness as unified rather than dual. Sperry reasoned that normal consciousness is a higher emergent entity that transcends the separate awareness in the connected left and right hemispheres, supersedes them in controlling thought and action, and integrates their activity. Alternatively, Bogen (1990) and many of us argue that normal consciousness is also dual, with partially separate parallel processing in the two hemispheres which sometimes does result in subjective feelings of conflict. Moreover, some normal subjects behave like split-brain patients"

So the question I ask you is:
Do you think that "normal" (unsplit) consciousness is split or whole?
How do you explain this?
