Emergence [Paperback]

Steven Johnson (Author)

Book Description

Publication Date: August 1, 2002

It is fast becoming clear that our lives revolve around the powers of emergence. Order arrives from the bottom-up, not top-down. Complexity is resolved through simplicity. Everywhere the same laws are obeyed, the same swarm logic is at work. "Emergence" looks at the cities we inhabit, the media frenzies we suffer and the games we play, showing how individual actions without central planning often create a wonderfully adaptive communal intelligence. In this compelling, revelatory book, Johnson investigates the artificial emergence which is bringing sweeping cultural and political change in its wake. Rich with insights into the future, this book allows us to witness the exhilating arrival and sudden ascendancy of a potent new idea.

This review is from: Emergence: The Connected Lives of Ants, Brains, Cities and Software (Hardcover)

This book covers the theory of emergence, which states that within a system of what seems to be anarchy, there are underlying rules that govern the pattern of behaviour and bring order out of chaos.

This books serves as an introduction to the field of emergence. It is something that is already happening around us, but we usually cannot see. The reason for this is that you need to look at a higher level then the individual organism. Ants can not see the society as a whole that they are members of. Just as we humans may have an understanding of the local community we are in and of ourselves, we need to step outside (or above) the city to understand how it functions. A city, like an ant colony does not have rules from the top as such, but rules that each occupant obeys, and it is these rules that give order to the chaos and make the resultant community behave like an organism as a whole.

I really wanted to like this book. But the level of information within it will make me put in into the light, popular fiction section of my bookshelf. One of the aspects of the book that really wanted me to give a good review is that the author makes a good introduction to the theory behind the comments system of Slashdot, the way people are chosen to rate comments and how good comments filter to the top. As such, I would have liked a review of the editorial process on Kuro5hin as well, since the two systems as fairly similar. In fact, I think the Kuro5hin system is better, because long time readers will see that the stories have moved away from an open source/linux focus to more cultural aspects, thus reflecting the change and growth of the community. But the idea of a Daily Me portal, that serves information that would suit us is explored heavily.

As I read the book though, an uneasiness came upon me, just as I do when reading books on neo-Darwinism. There is no mention of where these rules as such come from except through evolutionary survival or initial chance. If anything, the author implies that we are in a universe that had the initial conditions set, and left running. So we'd evolve or grow into who or what we are.

The idea that a God figure could be there, tweaking the parameters as the model runs, or even setting the initial conditions works against his ideas. This view is however explored in the chapter Control Artist, where the author comments on the development of software models, notably computer games. Games such as SimCity are discussed where the rules are set, but as a player we get to choose what gets built, what gets destroyed. Although here we are playing the Mayor of the City, the notion is the same; we control the macro level and not the micro level. But at the micro level, the software developer who built the game in the first place controls each inhabitant. Nothing really, is left to chance. Given the exact same initial conditions and same set of instructions the computer will create the same environment.

So, like most popular science books currently available it will educate you, entertain you and keep you occupied while reading it or totally bore you. But it is not a book of philosophy to base life on, which thankfully, the author has not tried to provide. It is very well researched, and the author seems on top of current trends and ideas. His writing style jumps around quite a bit, and some of the connections between topics might seem a little far fetched but it is an entertaining read as an introduction to the field of emergence theory.

Pet peeve 1: Notes. The notes section at the end is fairly extensive. But there are no foot notes in the book. The notes are indexed by page and quote. So as a reader you have to constantly check the notes section to see if there is a note or reference for the page you are reading.

Pet peeve 2: There was (for me) a glaring technical error on page 120.

This review is from: Emergence: The Connected Lives of Ants, Brains, Cities and Software (Hardcover)

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.

The book roams across a broad canvass discussing the behaviours of cities, ants, slime mould, software, the internet and politics as emergent systems.

It 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 at home and in business.
