Negative feedback as model for “training”

Negative feedback…is a way of reaching an equilibrium point despite unpredictable and changing external conditions.

The above quote is from Emergence: The Connected Lives of Ants, Brains, Cities, and Software by Steve Johnson, who goes on to say that negative feedback is a way of indirectly pushing a fluid, changeable system toward a goal.

Though not the context in the book, this definition and description of negative feedback is also an excellent definition of training (and, for that matter, learning). For what is training if not the process of getting to a point you want to be at based on continued refinement of what you are doing?
