Abstract
As one of problems before input into information-related-devices, there is the relation between a complete rationality working at the objective world and a definitive rationality of human recognizing it. The rationality working objectively can be expressed as what human had better originally recognize as a same or as a different when he observes two objects if we express it from a point of view he recognizes. This is true between two other objects at the same time or between one object at one time and the same object after some time passed and the difference is one to one between a part and a whole at the same time and before and after some time passes it is one to one between the operation working from outer and a part or a whole. On the other hand, because recognition of human is incomplete, he haven't been able to recognize as a same or a different. This is called as the definitive raionality. We make it clear that he feels opposition and contradiction when he cann't recognize as a different what he should recognize originally as a different. In order to approach this definitive rationality to the complete rationality, it is important to have the awareness of the issues and this is the essence of the concept analysis.
