New Questions: - Can we intentionally design for strong emergence, or is it always discovered post hoc? - Where is the line between emergent behavior and merely complex aggregation? --- ### **References** - Steven Johnson, *Emergence: The Connected Lives of Ants, Brains, Cities, and Software*. - Melanie Mitchell, *Complexity: A Guided Tour*. - Philip Anderson, “More is Different,” *Science*, 1972. - Stephen Wolfram, *A New Kind of Science*. - Wikipedia: https://en.wikipedia.org/wiki/Emergence - Kurzgesagt video on emergence: https://youtu.be/16W7c0mb-rE - TED Talk: Eric Bonabeau on swarm intelligence [The Ultimate Guide to Emergence](https://www.numberanalytics.com/blog/ultimate-guide-to-emergence) [The Emergence of 'Emergence'](https://journal.emergentpublications.com/Article/53f03ea1-5f9f-4ec8-a536-892eb4487413/github) [Emergence: The Key to Understanding Complex Systems](https://systemsthinkingalliance.org/the-crucial-role-of-emergence-in-systems-thinking/) [The Re-emergence of “Emergence”: A Venerable Concept in Search of a Theory | Institute for the Study of Complex Systems](https://complexsystems.org/publications/the-re-emergence-of-emergence-a-venerable-concept-in-search-of-a-theory/) [Emergence | Internet Encyclopedia of Philosophy](https://iep.utm.edu/emergence/) [Emergence is often misunderstood as a theory of everything explaining how novel forms of matter arise from fundamental properties.
