But in a network, the knowledge is emergent. The knowledge is not in any given individual, but it’s a property of the network as a whole. Consequently, it’s a knowledge that cannot, does not, exist in any individual, but only in the network as a whole. It’s emergent. It’s more complex in the sense that it is able to capture and describe phenomena that are not simple like cause and effect, but complex like the nature of societies or the nature of the weather. That’s a very loose characterization about it.
