[ Technology is] the instrumentality for accessing and using free energies in human societies for human and social purposes. - Ervin László

In some regions, under especially favorable conditions, the level of organization reaches that of enormously heavy organic substances, such as protein molecules and nucleic acids. Now the basic building blocks are given for the constitution of self-replicating units of still higher organizational level: cells. These systems maintain a constant flow of substances through their structures, imposing on it a steady-state with specific parameters. The inputs and outputs may achieve coordination with analogous units in the surrounding medium, and we are on our way toward multicellular phenomena. The resulting structures — organisms — are likewise steady-state patterns imposed steady-state patterns imposed on a continuous flow... The organic systems themselves, define the supra-organic (ecological or social) community. Ultimately the strands of communication straddle the space-time region within which the primary systems have come together, and those of its layers which provide conditions favorable to such structuration become organized as systems in their own right. We reach the level of the global (ecological, and on earth also sociocultural) system.

A system in one perspective is a subsystem in another. But the systems view always treats systems as integrated wholes of their subsidiary components and never as the mechanistic aggregate of parts in isolable causal relations.

In systems such as contemporary society, evolution is always a promise and devolution is always a threat. No system comes with a guarantee of ongoing evolution. The challenge is real. To ignore it is to play dice with all we have. To accept it is not to play God—it is to become an instrument of whatever divine purpose infuses the universe.
