I will admit I found it a bit hard to read so I'm not entirely sure but I think, more or less, they were saying we do think from the bottom up rather than the top down. Rather lending credence to my comments about knowing when you don't know - i.e. knowing instinctively before consciously, I like to think. 
Re the rainbow effect - my experience is that around the age of 10 is when I became self conscious and I think that is the same for many of us. So again I think that bears out what they are saying about personal awareness being a byproduct rather than being vital to function but it seems a vital part of the process now - you always want that bit of you to feel included.
