Right and left brain don’t phase me really. What 
really interests me is left and right visual fields 
because those are really anatomical realities. The 
brain—we don’t know what kind of real 
collaboration goes on between the right and left. 
But we know—and we know this from like hundreds 
of experiments—that the right visual field and the 
left visual field see the same thing, but differently. 
That is, the analysis of the field or the seizing of 
that field by the whole thinking and perceiving 
being are different.

It’s a bit like holding a bread knife if you are right-
handed. You hold the bread with your left hand
