The main research work in this thesis is to organize the intersubjectivity of Husserl¡¦s theory and to study the two documents of ¡§Ideas II¡¨ and ¡§Cartesian Meditations¡¨ which translate and reorganize the part of intersubjectiveity. The author talks about the ¡§Cartesian Meditations¡¨ first, the late publication, then ¡§Ideas II¡¨ and try to use a reverse method, form transcendental to empiricial, to explore the possibility of intersubjectivity and the trace of the phenomenology in French toward ethics and aesthetics. In addition, author organizes Schutz¡¦s criticism of intersubjectivity of the transcendental theory to contrast with the Husserl¡¦s viewpoint and poses the refutation of Schutz¡¦s criticism in the final part of this thesis. What is the possibility of intersubjectivity? This thesis itself has not been able to provide the concrete opinion. The author poses the "less then contented" as a basis of intersubjectivity, but it only retains in the appendix for the purposes of reference because of its lack of theoretical basis and the persuasiveness.
