"...whatever has made it into consciousness has already happened." Michael Gazzaniga (2011), p. 1636
Can one part of the brain truly “observe” another part? Not in real time. There is always a delay.
Thoughts are remnants of automatic brain processes that have temporarily captured our attention. If we are aware of a thought, we have recreated it.
