The Divide

from my flickr

Just read Iain McGilchrist's book on the divided brain. There is also a documentary video that summarizes the 1000 or so pages, which is difficult if not impossible. McGilchrist has a career spanning literature and neuro-psychiatry at the highest level. His thesis, formulated over 20 years is that our thinking and perception evolves from a confrontation between the verbal analytic side of our nature and the integrative perceptual side, and ideally should flow back and forth in a sort of collaboration to achieve good things.

His book has to err on the side of denotation to prevent attacks from the scientific culture which he criticises, and that is both its strength and weakness, it has to live in a left hemisphere world, defending the right, a bit like the opponents of our current demagogues, who need to use their tactics to get though a message. It is a losing game, but one that must be played for the long term.

I want to highlight the relationship to Jane Jacobs' ideas from her book on Systems of Survival where she makes a case for the healthy confrontation between cultural guardians and commercial facilitators. This work complements and consolidates her arguments across the history of the humanities and of the sciences.

Implicitly, the book links Dewey's (and Pirsig's) ideas on Quality and morals to the continental existentialists (finally!), but there is much more work to be done bridging the philosophies of the positivists with that of the continentals, especially in our English speaking cultures. There are glints of hope, for example Lakoff and Johnson's work, but too little uptake from what I can see.

Kahneman and Pinker are also present as critics in the background of McGilchrist's arguments, against thinking fast and favoring thinking slow, and arguing for the primacy of language over music. McGilchrist forcefully responds to Pinker's attack on his web site. I am also not sure how this relates to Chomsky's embedded linguistics, but we shall see. Chomsky can be quite defensive, as Tom Wolfe writes.

Existence precedes essence is so well presented, with forceful cultural, scientific and artistic evidence by someone raised in the positivist tradition. We (the West) need to budge away from Platonism. This key to our success, our domination of the environment, may no longer work now that we are on the downside of the arc of sustainability. This crisis may be a touchpoint, who knows.

I am listening to Joni Mitchell who understood that we were heading this way, back in the late sixties.
