By Juval Portugali

Complexity, Cognition and the town goals at a deeper knowing of urbanism, whereas invoking, on an equivalent footing, the contributions either the challenging and delicate sciences have made, and are nonetheless making, while grappling with the numerous matters and elements of local making plans and dynamics. during this paintings, the writer is going past in basic terms seeing town as a self-organized, rising development of a few collective interplay among many stylized city "agents" – he makes the an important step of attributing cognition to his brokers and hence increases, for the 1st time, the query on find out how to take care of a fancy approach composed of many interacting complicated brokers in essentially outlined settings. hence, the writer finally addresses problems with sensible relevance for city planners and choice makers.

The e-book unfolds its message in a principally nontechnical demeanour, which will supply a extensive interdisciplinary readership with insights, principles, and different stimuli to motivate additional study – with the twofold target of additional pushing again the limits of complexity technological know-how and emphasizing the all-important interrelation of difficult and smooth sciences in spotting the cognitive sciences as one other invaluable aspect for significant city studies.

The second message starts from exactly the other direction: indeed there are significant resemblances between natural complex systems and cities, but beyond the similarities there are also significant differences that cannot be ignored. Firstly, cities are dual complex systems in the sense that each of their elementary parts – the urban agents (individuals, households, firms, or public agencies) – is a complex system, too. Secondly, and related to the above, cities are artifacts, that is to say, the product of humans’ intentions, aims, politics, learning, and hopes.

These parallel developments, discussed in some detail in Chaps. 3 and 4, are interesting and significant in several respects: First, there are several similarities between complexity theories and PPD in their perception of reality, for instance, both emphasize change, chaos and instability: PPD approaches by claiming that these properties are typical of postindustrial globalized society, that is to say, of the age of postmodernity and the new postmodern condition, while complexity theories by claiming that change, chaos and instability are some of the properties that characterize a certain type of natural and artificial systems, namely, open, complex, self-organizing systems which are far from equilibrium.
