Gordon's work on ant colonies provides a tractable and easily understandable way in to both systems thinking and understanding complexity. By using ants and ant colonies as the object of analysis, Gordon asks questions that all systems analysts would. From exploring how actors sense and respond to their environment, to inquiring as to how the system self-regulates behaviour such as foraging for food, this work is grounded firmly in science, while being clear about what answers we still have not discovered.

My key critique of this work is that the last chapter on modelling feels undone; I would really have liked to see systems diagrams of the phenomena visualised.
