rpose, but it always has one and the same purpose. Haemoglobin as a system is always intended for the transfer of oxygen only, a car is intended for transportation and the juice extractor for squeezing of juice from fruit. One can use the juice extractor made of iron to hammer in a nail, but it is not the juice extractor system's purpose. This constancy of purpose obliges any systems to always operate to achieve one and the same goal predetermined for them. p> The principle of goal-setting. A car is intended for transportation, a calculator - for calculations, a lantern - for illumination, etc. But the goal of transportation is needed not for the car but for someone or something external with respect to it. The car only needs its ability to implement the function in order to achieve this goal. The goal is to meet the need of something external in something, and this system only implements the goal while serving this external "something". Hence, the goal for a system is set from the outside, and the only thing required from the system is the ability to implement this goal. This external "something" is another system or systems, because the World is tamped only with systems. Goal-setting always excludes independent choice of the goal by the system. The goal can be set to the system as the order/command and directive. There is a difference between these concepts. The order/command is a rigid instruction, it requires execution of just "IT" with the preset accuracy and only "IN THAT MANNER" and not in any other way, i.e. the system is not given the "right" to choose actions for the achievement of the goal and all its actions are strictly defined. Directive is a milder concept, whereby the "IT" is set only the given or approximate accuracy, but the right to choose actions is given to the system itself. Directive can be set only to systems with well developed management unit/control block which can make choice of necessary actions by itself. None of the systems does possess free will and can set the goal before itself; it comes to it from the outside. But are there any systems which are self-sufficient and set the goals before themselves? For example, we, the people, are sort of able of setting goals before ourselves and carry them out. Well then, are we the example of independent systems? But it is not as simple as it may seem. There is a dualism (dual nature) of one and the same concept of goal: the goal as the task for some system and the goal as an aspiration (Desire) of this system to execute the goal set before it: the Goal is a task representing the need of external operating system (Super system) to achieve certain predetermined result; the Goal is an aspiration (desire) to achieve certain result of performance of the given system always equal to the preset result (preset by order or directive). The fundamental point is that one super system cannot set the goal before the system (subsystem) of other super system. It c...
