A property of a system or aggregated whole which is not shared by components of the system or the constituents of that body. | A property of a system or aggregated whole which is not shared by components of the system or the constituents of that body. | ||
Joe Norman has a great example of emergence and [[reductionism|irreducibility]] at [https://open.spotify.com/episode/4iX7DPthz47YdkPB7MWHJG? Risky Conversations]: If you try to break a [[Möbius loop]] into smaller parts, you lose its one-sidedness. Each of its segments has ''two'' sides. You can join any of its segments together, and they still have two sides. It is only when you twist the emerging structure and join it back on itself that the second side vanishes | Joe Norman has a great example of emergence and [[reductionism|irreducibility]] at [https://open.spotify.com/episode/4iX7DPthz47YdkPB7MWHJG?

So, “wetness” is a property of water, but not of a molecule of H<sub>2</sub>0. “Consciousness” is a property of a brain, but not the neural activity that ''comprises'' it.<ref>This [[paradox]] has derailed the philosophy of mind for hundred of years.</ref> “[[Bureaucracy]]” is an emergent property of a [[financial services]] organisation, not the individual communications within that organisation that make up the organisation. Well, not many of them, anyway. | So, “wetness” is a property of water, but not of a molecule of H<sub>2</sub>0. “Consciousness” is a property of a brain, but not of the neural activity that ''comprises'' it.<ref>This [[paradox]] has derailed the philosophy of mind for hundred of years.</ref> “[[Bureaucracy]]” is an emergent property of a [[financial services]] organisation, not the individual communications within that organisation that make up the organisation.

Nonetheless in each case the emergent property is a function not of the system as a whole, where it presents, but of its individual components, ''where it does not''. So changing an emergent property is tricky. | Nonetheless in each case the emergent property is a function not of the system as a whole, where it presents, but of its individual components, ''where it does not''.
