“The left hemisphere seems to feel quite defensive-in a strange way insecure-about the right hemisphere; and, if this is so, verbal criticism of intuitive thinking becomes suspect on the ground of motive. Unfortunately, there is every reason to think that the right hemisphere has comparable misgivings -expressed nonverbally, of course- about the left.”

“Major scientific insights are characteristically intuitive, and equally characteristically described in scientific papers by linear analytical arguments.

You struggle against that push, and start to feel your stomach protest. It's not so much even a type of seriousness as it is a circumstance, into which you pass by slow degrees. I've never seen this sufficiently examined. It mutates into a less-unreal reality that still seems different, somehow, than being fully present. Self hate is rarely unconditional.”
