Already thrumming

The asymmetry of structure favors the left hemisphere. 

The left hemisphere builds systems up a piece at a time. Such systems convey what they convey but they also exclude what does not fit into the system. Linguistic systems disqualify everything that cannot be spoken; rational systems disqualify everything that cannot be reasoned. 

The right hemisphere operates with respect to the stuff that comes into full view through disclosure, through the uncovering of something already extant, already given, already thrumming with the pulse of life. Man cannot create life, he can only permit it or deny it. Such right hemispheric systems of determination either by negation or by the refusal to negate are at a disadvantage to the pro-active systems of the left hemisphere, which re-present in a forceful and compelling way what it claims to know with certainty and with overly self-serving conviction. 

"Language in itself (to this extent the post-modern position is correct) can only refer to itself, and reason can only elaborate, 'unpack' the premises from which reason must begin, or that validates the process of reasoning itself – those premises, and the leap of faith in favor of reason, have to come from behind and beyond, from intuition or experience." (The Master and His Emissary, Iain McGilchrist, 2009; page 229).
