We begin to ponder how the concept of stigmergy might illuminate the emergent characteristic of complex systems.
>Stigmergy is a form of self-organization. It produces complex, seemingly intelligent structures, without need for any planning, control, or even direct communication between the agents. As such it supports efficient collaboration between extremely simple agents, who may lack memory or individual awareness of each other. wikipedia 
The concept was first introduced by Pierre-Paul Grassé in 1959 to refer to termite behavior. The concept was that behavior leaves traces that shape subsequent behavior in ways that allow order to organically emerge. This concept was develop with his study of termites. In that study, he observed:
>"Stigmergy manifests itself in the termite mound by the fact that the individual labour of each construction worker stimulates and guides the work of its neighbour." wikipedia
In a sense, then, these traces are remembered patterns that shape behavior in a way that new patterns of increased complexity an be iteratively formed.
Some have hypothesized that this concept goes a long way to explain the rise of open source software and collective wikis such as Wikipedia. Others have suggested that social movements such as the Occupy Movement can also be described through this model.
Patterns, behaviors and patterns – a triple energized. A model we sense that can be aligned with Friston's Active Inference process theory.
