This is a very readable popular science book about how complex systems emerge from lower level behaviour. It covers slime mold, ants, cities, the Internet and the human brain. It was written in 2002 and the Internet section felt qite outdated, but I really enjoyed the sections about cities, and how neighbourhoods develop. I liked the idea of cities as a giant communal database for information collection, storage and retrieval. ( )

As of late, “Emergence” seems to be the hottest buzz word tossed around the crit spaces and seminar rooms of my chosen discipline. Thus it was important that I finally read something about just what the hell the term means. As usual, the unflagging Johnson never fails to enthrall. Who can deny the power of such observations as, “in the case of the Middle Ages, we can safely say that the early village residents shat themselves into full-fledged towns.”? He occasionally descends into the hackneyed territory of predictive cyber-nerd-speak, but he quickly segues into something else in his quest to uncover a consilience among ants, brains, Jane Jacobs, and the World Wide Web (apparently not invented by Albert Gore, but one Tim Berners-Lee. Coincidentally I voted for Tim in 2000).

Alas, this book seems to shore up my preconceived opinion that “emergence” will have little more than a tenuous relationship with some student’s “architecture” project for a Museum of Humanism in a previously Iron Curtainized locale. It’ll merely be used as one of those dialogic Red Herrings that make me look like the ass when I point out that the project lacks stairs… and walls. I suppose those things will emerge later on. ( )

Steven Johnson is an excellent pop culture / business writer. Emergence is up to the high standard set by his Everything Bad Is Good For you. Everything will be easier to digest for most. Everything deals with readily accessible pop culture. Johnson's fascinating thesis in Everything is we are smarter due to pop culture. Emergence is more remote concentrating on history of emergence theory in ants and bees. Johnson builds a bridge between our most massive emergent system, the web, and nature. His foundation is solid, but he demurs at the last moment for some good reasons. Turns out there are differences between nature's emergent systems and the web. As a "thought experiment" this book helps see and think of web movement differently. Johnson's abstract comparison between biological and technical systems is what makes Emergence fascinating and layered. I am working notes into a database and it is taking several days. ( )

This is an excellent thought provoking book that I thoroughly enjoyed, and provides a good introduction to the topic of emergence dealing with the bottom-up creation of intelligent behaviour from lower level less intelligent behaviour.

This is perfectly illustrated by the example of harvester ants whose colonies exhibit intelligence and learning that no individual ant possesses. The complexity of the colony and its structure is constructed by the behaviours of ants whose vocabulary extends to only ten discrete actions. In a real sense the ants do not consciously create the colony but it is created through the interactions between the ants. There is no helicopter view of the colony held by any ant, no master plan, yet the colony is created. It emerges from the lower level actions of the ants.

Interesting though the behaviour of ants is, the book goes on to cite many other examples much closer to home, not the least of these is the creation of cities which is shown to parallel this emergent approach.

The book explores how our mindset makes it difficult to see and accept the creation of complex intelligent behaviour in this emergent way. Our thinking tends to look for a top-down leader driven explanation, the bird in the flock that sets the direction, rather than each bird in the flock following a simple set of rules with the flock behaviour emerging as a consequence.

For me the book provided real insights into the prevalence of emergent systems and points to computer games such as Sim City which allow us to glimpse the creation and operation of emergent worlds.

Whilst the book roams across a broad canvass discussing the behaviours of cities, ants, slime mould, software, the internet and politics as emergent systems, it does not focus specifically on business organisations. However to the discerning reader the profound importance of the message of emergence and its implications will resonate in every business.

This is an excellent and stimulating read that introduces the principles of emergence and may change the way you look at how a host of systems operate including those involved in business operation and business change. ( )
