“The central attribute of human conscious experience, so fundamental, in fact, that we take it for granted, don’t pause to think about it, is the sense of unity. You’ve got a diversity of sensory experiences. You see things, you listen to things. This harks back to what I was saying about synesthesia. You taste things. You have hundreds of memories throughout a lifetime. Yet you think of yourself as a unified person. Yet all of these happen to you… Despite this diversity of sensory experiences, this bewildering sensory cognitive blitz of memories and sensory impressions I experience unity. How does that come about?”
