one super system cannot set the goal before the system (subsystem) of other super system. It can set the goal only before this super system which becomes a subsystem in respect of the latter. We can set the goal before ourselves, but we always set the goal only when we ar e missing/lacking something, when we suffer. Suffering is an unachieved desire. Any physiological (Hunger, thirst), aesthetic and other unachieved desires makes us suffer and suffering forces us to aspire to act until desires are satisfied. The depth of suffering is always equal to the intensity of desire. We want to eat and we suffer from hunger until we satisfy this desire. As soon as we take some food, the suffering ceases immediately. At that, the new desire arises according to "Maslow pyramid". Desire is our goal-aspiration. When we realize our wish we achieve the objective/goal. If we achieve the objective we cease to act, because the goal is achieved and the wish disappears. If we have everything we can only think of, we will not set any goals before ourselves, because there is nothing to wish, since we have everything. Therefore, even a human being with all its complexity and developmental evolution cannot be absolutely independent of other systems (of external environment). Our goals-tasks are always set before us by the external environment and it incites our desire (goal-aspiration) which is dictated by shortage of something. We are free to choose our actions to achieve the goal, but it is at this point where we are limited by our possibilities. We do not set the goal-task, we set the goals-aspirations. Then if it is not us, can there be other systems which can set goals before themselves regardless of whatsoever? Perhaps, starting from any certain level of complication the systems can do it themselves? Such examples are unknown to us. For any however large and difficult system there might be another, even higher system found which will dictate the former its goals and conditions. Nature is integrated and almost put in (good) order. It is "almost" put in order, because at the level of quantum phenomena there is probably some uncertainty and unpredictability, i.e. unconformity of the phenomena to our knowledge of physical laws (for example, tunnel effects). It is this unpredictability which is the cause of contingencies and unpredictability. Contingency/stochasticity and purposefulness are mutually exclusive. p> Principle of performance of action. Any system is intended for any well defined and concrete goal specific for it, and for this purpose it performs only specific (target-oriented) actions. Hence, the goal of a system is the aspiration to perform certain purposeful actions for the achievement of target-oriented (appropriate) result of action. The plane is designed for air transportation, but cannot float; for this purpose there is an amphibian aircraft. The result of aircraft performance is moving by air. This result of action is e...
