The view from complexity claims that we cannot know complex things completely... modest positions are inescapable... We can increase the knowledge we… - Paul Cilliers

In our analysis of complex systems (like the brain and language) we must avoid the trap of trying to find master keys. Because of the mechanisms by which complex systems structure themselves, single principles provide inadequate descriptions. We should rather be sensitive to complex and self-organizing interactions and appreciate the play of patterns that perpetually transforms the system itself as well as the environment in which it operates.

Each element in the system is ignorant of the behaviour of the system as a whole, it responds only to information that is available to it locally... If each element 'knew' what was happening to the system as a whole, all of the complexity would have to be present in that element.

There is no over-arching theory of complexity that allows us to ignore the contingent aspects of complex systems. If something really is complex, it cannot by adequately described by means of a simple theory. Engaging with complexity entails engaging with specific complex systems. Despite this we can, at a very basic level, make general remarks concerning the conditions for complex behaviour and the dynamics of complex systems. Furthermore, I suggest that complex systems can be modelled.
