Society can be viewed as a multicellular organism, with individuals in the role of the cells. The network of communication channels connecting individuals then plays the role of a nervous system for this superorganism, i.e. a “global brain.”
It is an old idea, dating back at least to the ancient Greeks, that the whole of human society can be viewed as a single organism. Many thinkers have noticed the similarity between the roles played by different organizations in society and the functions of organs, systems, and circuits in the body.
If cells aggregate to form a multicellular organism, then organisms might aggregate to form an organism of organisms: a superorganism.
Human society is still an ambivalent system, balancing between individual selfishness and collective responsibility.
