- * D-12. Conflict, if important in the sense of affecting the critical
- * variables in the systems that have lost control, will lead to
- * reorganizations that escalate the conflict, bringing both loop gains
- * into the high region and increasing the outputs to their maximum. This
- * will continue until one or both organisms dies, or until one organism
- * reorganizes in a way that eliminates the conflict altogether.
- *
- * D-13. Therefore the normal steady-state interaction between organisms
- * will be one that involves no conflict.
- *
- * D-14. Interactions without conflict require that independent organisms
- * in close contact control perceptual variables that are linearly
- * independent of each other. This is the solution to conflict that will
- * occur, through reorganization, if both organisms survive. It is the
- * only solution, other than breaking contact, that can persist over
- * time.
- *
- * D-15. When there are no conflicts, each organism controls variables
- * that are independent of the other's controlled variables. The actions
- * of each organism can amount to disturbances of variables or parametric
- * disturbance of the other's control systems. These disturbances,
- * however, remain within the range where each system can continue to
- * control all its perceptions by varying its own output actions. Each
- * organism continues to maintain its own critical variables near their
- * reference levels, independently of the other.
- *
- * D-16. The shared environment will then come to a state in which it
- * simultaneously satisfies all the reference conditions in both
- * organisms. This can involve a close intertwining of physical
- * relationships, because for the behaving systems, "environment" is all
- * that is not CNS or reorganizing system. It includes, therefore, the
- * bodies of both systems, not just the world between the systems.

- I wonder how much of the above holds if you replace "organism"
- by ECS.
-
- *D-14. Interactions without conflict require that independent organisms
- * in close contact control perceptual variables that are linearly
- * independent of each other.
-
- Can you elaborate a little on the coexistence of "close contact" in
- one hand "control of linearily independent variables" on the other.
- I can see that if 2 systems perceive the same point in the plane,
- one controlling for the x dimension and one for the y, then they
- can achieve their goals simultaneously, but in what sense are they
- then in "close contact"? Since they are controllin for lin. indep.
- perceptual variable, they are virtually disconnected from each
- others (from their perceptual point of view). Only some hypothetical
- 2-dimensional CEV makes them connected.
