The barycenter of research of this dissertation lies in intensive researches for the theories of intersubjectivity (such as Kant's,Fichte's,Hegel's,Husserl's,Max scheler's,Schutz's,Martin Buber's,Merleau-ponty's,Sartre's,Habermas's etc.)of traditional epistemology philosophy,especially for the theories of intersubjectivity of modern western philosophy. The dissertation attempts to give the light to the interlocution and collision among various theory paradigms by a morphological investigation ,to work out respectively differrent rationality and limitation ,so as to avoid the inclination of suberjectivism and pure idealism and non-historism .The evaluation criterion of this dissertation follows as :the foundation stone of intersubjectivity is the lifeworld and communicational practice .The relations between the various subjects is multi-layered and heterogenous. intersubjectivity and the relation between subject and object is both opposing and unifying. There is a tension between historical and valual dimensionality,at the same time ,it becomes the foundation of the realization of the whole comprehension of intersubjectivity in the dimensionality of philosophical anthropology.To a certain extent ,the research takes on the value and significance of the phylogeny of philosophical thought of intersubjectivity as well. The dissertation academically explores how intersubjectivity is a philosophical issue,defmitely puts forward six modes of comprehension of intersubjectivity,and give intersubjectivity category a definition of broad sense,simultaneously divide the intersubjectivity theories into four forms ,that is ethic form ,epistemology form,existentialism form and social and historical form,which are the important innovations of the research .
