The Archdruid and I are thinking the same thinks.

"With this in mind, let’s return to the distinction discussed in last week’s post. I noted there that a city is a human settlement from which the direct, unmediated presence of nature has been removed as completely as the available technology permits. What replaces natural phenomena in an urban setting, though, is as important as what isn’t allowed there. Nearly everything that surrounds you in a city was put there deliberately by human beings; it is the product of conscious human thinking, and it follows the habits of human thought just outlined. Compare a walk down a city street to a walk through a forest or a shortgrass prairie: in the city street, much more of what you see is simple, neat, linear, and logical. A city is an environment reshaped to reflect the habits and preferences of the human mind.

I suspect there may be a straightforwardly neurological factor in all this. The human brain, so much larger compared to body weight than the brains of most of our primate relatives, evolved because having a larger brain provided some survival advantage to those hominins who had it, in competition with those who didn’t. It’s probably a safe assumption that processing information inputs from the natural world played a very large role in these advantages, and this would imply, in turn, that the human brain is primarily adapted for perceiving things in natural environments—not, say, for building cities, creating technologies, and making the other common products of civilization.

Thus some significant part of the brain has to be redirected away from the things that it’s adapted to do, in order to make civilizations possible. I’d like to propose that the simplified, rationalized, radically information-poor environment of the city plays a crucial role in this. (Information-poor? Of course; the amount of information that comes cascading through the five keen senses of an alert hunter-gatherer standing in an African forest is vastly greater than what a city-dweller gets from the blank walls and the monotonous sounds and scents of an urban environment.) Children raised in an environment that lacks the constant cascade of information natural environments provide, and taught to redirect their mental powers toward such other activities as reading and mathematics, grow up with cognitive habits and, in all probability, neurological arrangements focused toward the activities of civilization and away from the things to which the human brain is adapted by evolution."
