tive feature of any systems - living, natural, social, financial, technical, etc. Consequently, in order to achieve the goal any object of our World should function, make any purposeful actions, operations (in this case the purposeful, deliberate inaction is in some sense an action, too). Action is manifestation of some energy, activity, as well as force itself, the functioning of something; condition, process arising in response to some influence, stimulant/irritant, impression (for example, reaction in psychology, chemical reactions, nuclear reactions). The object's action is followed by the result of action (not always expected, but always logical and conditioned). The purpose of any system is the aspiration to yield appropriate (targeted) result of action. At that, the given object is the donor of the result of action. The result of action of donor system can be directed towards any other system which in this case will be the recipient (Target) for the result of action. In this case the result of action of the donor system becomes the external influence for the recipient system. Interaction between the systems is carried out only through the results of action. In that way the chain of actions is built as follows: ... в†’ (external influence) в†’ result of action (external influence) в†’ ... The system produces single result of action for single external influence. No object operates in itself. It cannot decide on its own "Here now I will start to operate "because it has no freedom of will and it cannot set the goal before itself and produce the result of action on its own. It can only react (act) in response to certain external influence. Any actions of any objects are always their reaction to something. Any influence causes response/reaction. Lack of influence causes no reaction. Reaction can sometimes be delayed, therefore it may seem causeless. But if one digs and delves, it is always possible to find the cause, i.e. external influence. Cognition of the world only falls to our lot through the reactions of its elements. Reaction (from Latin "re" - return and "Actio" - action) is an action, condition, process arising in response to some influence, irritant/stimulant, impression (for example, reaction in psychology, chemical reactions, nuclear reactions). Consequently, the system's action in response to the external influence is the reaction of the system. When the system has worked (responded) and the required result of action has been received, it means that it has already achieved ("quenched") the goal and after that it has no any more goal to aspire to. Reaction is always secondary and occurs only and only following the external influence exerted upon the element. Reaction can sometimes occur after a long time following the external influence if, for example, the given element has been specially "programmed" for the delay. But it will surely occur, provided that the force of the external influence exceeds ...
