To correctly cultivate a community one must ensure individuals and groups can flourish within it. Without the possibility of evolution any organism or organisation is doomed to failure or in the best case scenario become an irrelevant vestigial form of it’s true nature. To keep the community innovative and true to it’s ideals it is also important to not have a fixed mentality.
We must allow adaptability in the face of change, disaster or loss of resources. The community must be prepared.
