10 years ago Alasdair Turner (2002) reviewed Self-Organization and the City by Juval Portugali. Now, the same author published a new book where cognition pops up in the title. The review by Turner was very positive and I am also inclined to express my admiration: What a book! It took me some time to digest it, but I strongly recommend it to scholars who work on spatial agent models. On the other hand, I would like to warn the readers as the book suggests a synergetic approach to agent-based modelling, which many of us are unfamiliar with. Moreover, although being almost perfect, the book missed something that crept into my brain while reading these 400 pages.
