 More recently, Nagel (1971), Davidson (1980), Dennett (1991, 1992), O’Brien and Opie (1998), and Rosenthal (2003) have all urged in one way or another that the mind’s unity has been overstated. The point these people make is not just that the mind works mostly out of the sight and often out of the control of consciousness. Virtually everyone agrees on that and the point would in no way tell against there being a real unity of some kind in the part that does enter consciousness. Rather, they maintain that not even all conscious states are unified with other conscious states.
