Chapters 6-9 adopt a “mental trip” via a number of “environments”, more and more broader in scope, suggesting to the reader the best way to realize therein keep an eye on structures that, by means of their ubiquitous presence, make the area attainable in all its manifestations. ultimately bankruptcy 10 covers rules a few self-discipline of regulate structures and the human elements of control.

For this reason systems thinking states: if we really want to “understand” the world and its changes, it is not enough to reason in terms of chains of causes and effects between variables; we must instead get used to circular thinking. In other words, we must be aware that every variable is not only the cause of variations in variables connected down the line in the causal chain but that the causal chain can become a loop, since the last variable in the chain can be the cause of the first variable, which thus becomes “the effect of its effects,” thereby creating a circular connection.

Following Senge’s fifth discipline, I hope not to be too pretentious in calling the discipline of control systems the sixth discipline, that is: the discipline of the control of the individual, the collectivity, organizations, and the ecosystem.

The subsequent section will consider a “ring” that shows a typical explosive process, in which a variable reinforces itself through increases generated by the variable itself.
