“The classical Greek philosophers, Aristotle and Plato, established some important systems ideas. Aristotle reasoned that the parts of the body only make sense in terms of the way they function to support the whole organism and used this biological analogy to consider how individuals need to be related to the State. Plato was interested in how the notion of control, or the art of steersmanship (kybernetes), could be applied both to vessels and the State. Ships had to be steered safely toward harbour by a helmsman. A similar role needed to be followed in societies if they were to prosper.”
