Cormac McCarthy, author of novels like No Country for Old Men and The Road, is, believe it or not, interested in physics and complex systems. Writing in Nautilus (great publication), he muses on language and the unconscious in The Kekulé Problem.

The shoehorn into the discussion is that people solve problems when they are asleep. Kekulé is only the most famous for this; falling asleep and solving the problem of the chemical structure of Benzine. The point is that the image he saw, that revealed the structure, did not contain any language. That is because it is from the unconscious.

Read the article to find out why the unconscious and language are separate. Is it biology, did it evolve, or are they simply incompatible? McCarthy jumps between psychology, biology, philosophy in his quest for an answer. He gets help by discussing with his friend and colleague David Krakauer, both from the Santa Fe Institute (home of really smart people). He ends up solving the problem after a ten-hour lunch with Krakauer and yes, some sleep.

This article reminds me of two other books. The Third Culture was the first collection of essays I read by John Brockman, a literary agent. He assembled a collection of scientists (Gould, Dawkins, Minsky, Schank, Pinker, Penrose, Smolin, Kauffman, and especially Gell-Mann, also at Santa Fe) to answer questions usually reserved for theologians and philosophers. C.P. Snow postulated that Science and Literature would merge into a “third culture.” It had a profound effect on my thinking. Brockman puts a similar book out each year, addressing a new question. Find him at the Edge.

Language is metaphor, and that is what makes us human. China Mieville writes of an alien race inhabiting a trading outpost at the edge of the civilized universe in Embassytown. The heroine watches as the Ariekei try to lie and fail, repeatedly. They are not built that way. Their Language requires people to speak in two voices at the same time. Humans that are conjoined twins fill the role of Ambassadors. When a linguistic “virus” invades, all hell breaks loose.

Which brings us back to language. It language itself just a virus, a parasite, riding on the cerebellum and medulla, causing the cerebrum to develop grotesquely large? Read McCarthy.
