| Subject and object is a pair of important philosophy category, the relation of Subject and object is one problem that any epistemology has to answer and explain. The fact of Philosophical history tells us, Philosophers must involve subject and object of cognition so long as they inspect problem of cognition, no matter if they Explicitly Propose subject and object category. The view on subject and object as well as their relation is cornerstone of researching and solving epistemological problem. One basic reason that emergence epistemology can hold important status in contemporary psychology and epistemology as well as do remarkable contribution to development of contemporary psychology and epistemology is that Piaget has original and profound opinion.Piaget uses subject and object category in strict epistemological significance. Piaget thinks that subject and object in epistemological significance does not exist when epistemology occurs, regardless of primitive human or newborn baby. Of course, subject and object category of epistemological significance also doses not exist. He thinks that subject and object as well as their category of epistemological significance is constructed by subject's activity. On Piaget's pinion, as epistemological two-pole, subject and object both mutually oppose and mutually depend. Moreover, Piaget think cognition exactly comes from interaction between subject and object. This makes him surpass traditional epistemology in epistemological origination. Moreover Piaget's viewpoint extremely approaches Marxist viewpoint that originates from practice. Especially important, Piaget think the interaction between subject and object is displayed by assimilation and compliance in the course of occurrence and development of cognition.Taking his psychological research as the foundation, Piaget not only discusses interaction of subject and objects but also does remarkable contribution to rich and develops theory on relation of subject and object. But like any theory , his theory is not perfect and it also has some limitation. Therefore, we regard correctly Piaget's theory on relation of subject and object to absorb its essence and rejects it's dregs as well as rich and develop Marxism epistemology, in which significance of researching Piaget's theory exactly lies. Until today, Piaget's theory has still important significance to cognitive correctly, rich and develop Marxism epistemology. Moreover Marxism as one open and scientific theory also needs exchange with other philosophical faction. It may model reasonable fact in the course of exchanging to unceasingly rich and develop itself. |
