So in summary systems thinking is about closing the gap to an ideal future state using and focusing on individuals while complexity thinking is about understanding the present, and evolving through collective action to a future state which could not be fully anticipated but which is sustainable and resilient. Now I know its a lot more complex than that, and also that some of the greats before popularisation are probably turning in their graves, or their emeritus chairs when they see what has happened. However systems thinking is pervasive, and its linked with models and ideas such as memes and Dawkin’s attitudes in general, i.e. we have an emphasis on causality at the cost of evolution. ~ Dave Snowden
