The human brain has a network structure that is both local and global. There are small, local modules that perform certain functions, and they are typically close to other modules that support those functions. But there are also huge neurons known as giant fusiform cells that allow for global connectivity across the brain. Giant fusiform cells are only found in the apes, and they are found in the largest number in humans. This combination of local and global that reaches a high degree of complexity in humans is what allows for the high intelligence of apes in general, and humans in particular.
There have been moves across the world–most notably, the EU–to create more globalized, more centralized political structures. Roger Scruton argues that we shouldn’t do away with the nation-state so easily, and he argues that it’s the highly-globally-connected wealthy elites who are pushing for things like the EU and even more global governance. At the same time we are seeing a push for a stronger EU, we are also seeing a pushback with the Brexit vote last year, and also more and more desire for local political control, especially in Spain and the U.K. With many of the independence movements, though, there is a simultaneous desire to remain part of the EU.
We can understand this by thinking about the network structure of the human brain. The global elites who are more comfortable with each other than with their countrymen are the equivalent of the giant fusiform cells. The problem arises when they think the world ought to be just like them. But that’s not the reality among human beings. A brain of only giant fusiform cells wouldn’t be a healthy, productive, or likely living brain. Most people are, like most brain cells, part of a local, specialized area. They have their own local culture, religious beliefs, and industries, among other things. And they persist in the face of global culture.
The point is that those who wish to have a more globally connected world are right, and those who wish to maintain their local cultures and mores are right. We need to be both more local and more global–and have many areas of unity in between. We need a global civilization where the Scots can be Scottish, the Welsh can be Welsh, the English can be English, and they can all be British; where the British can be British, the French can be French, the Spanish can be Spanish, and they and the rest of Europe can also be Europeans. And all regions can have a weak connection through the UN. We need strong local cultures as well as natural classical artists with global reach. We need all of this simultaneously. The more the globe evolves to match the network structure of the human brain, the healthier humanity as a whole will be.
