"There has to be a constant flow of energy to maintain the organization of the system and to ensure its survival. Equilibrium is another word for death."
"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."
"A certain theory of representation implies a certain theory of meaning - and meaning is what we live by."
"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."
"I do not know whether it was the will of God, or just an evolutionary accident, but as it happens I am Afrikaans. This is a circumstance with which I am normally perfectly content. The truth is that I actually do not think about it too much, just as I do not think about it too much that I have a liver. The current flutterings about Afrikaans, however, I find disturbing. It is not doing the image of Afrikaners, and hence also of Afrikaans, any good.A mere ten years after the end of apartheid (yes, there was such a thing, and it was evil) to beat ones chest in such a self-justificatory manner, is bad taste morally.... We are … being called up by certain parties to mobilise for Afrikaans, to fight for the survival of Afrikaans, and for minority rights. The problem is, however, that I do not see myself currently as part of a minority. When, in the 1970s and 1980s, as an Afrikaner, I resisted apartheid – and not in the 1990s when it became fashionable – then I felt myself part of a minority. At present I mainly find myself with an enormous feeling of moral relief. I would now like to carry on with my life and make a constructive contribution at the level of content. I do not wish to have to write letters like this one."
"The view from complexity claims that we cannot know complex things completely... modest positions are inescapable... We can increase the knowledge we have of a certain [complex] system, but this knowledge is limited... The fact that our knowledge is limited is not a disaster, it is a condition for knowledge. Limits enable knowledge."
"In order to constitute a complex system, the elements have to interact, and this interaction must be dynamic."
