David is a visionary. I appreciate his ability to present and explain complexity in its many forms. His subtle 'word art' has no peer. I will not be surprised at all to see THE theory of complexity emerge from the Santa Fe Institute.

Great way to conceptualize the Complex Systems perspective vis a vis the ones relevant to other disciplines. One other interesting and related concept is that of causal emergence: the idea that the causal relationships between the components of a system change as the system evolves, leading to the emergence of new causal relationships that cannot be easily predicted or explained by studying the individual components alone. It posits that the emergent properties and behaviors of a complex system are not simply the sum of the properties and behaviors of its individual components, but are the result of the complex causal relationships between those components.
