This is the website of the Principia Cybernetica Project (PCP), an international organization. The Project aims to develop a complete philosophy or "world-view", based on the principles of evolutionary cybernetics, and supported by collaborative computer technologies. To get started, there is an introduction with background and motivation, and an overview, summarizing the project as a whole

Principia Cybernetica tries to tackle age-old philosophical questions with the help of the most recent cybernetic theories and technologies.

Beyond the fact that these things are all networks of some kind, and that they are complex, it may appear that they have little in common, hence that the term "complex system" is vacuous. However, all complex systems are held to have behavioural and structural features in common, which at least to some degree unites them as phenomena. They are also united theoretically, because all these systems may, in principle, be modelled with varying degrees of success by a certain kind of mathematics. It is therefore possible to state clearly what it is that these systems are supposed to have in common with each other, in relatively formal terms.
