Husserl's Transcendental Consciousness Theory The Main Issues

In E.Husserl's later stage,he thought over how to get through from"transcendental ego"to objective existence,objects and other persons.So,he initiated a new philosophical field"intersubjectivity"theory ,based on his transcendental philosophy. E.Husserl tried his all best to research this new field, and enlightened other people fundamentally. However, this theory was as the result of a irrational assumption,going out of ego and being to objectivity.So, E.Husserl failed.Through comprehending the CARTESIANISCHE MEDITATIONEN and other related documents,I'll try to gain a clear train of E.Husserl's thoughts,and research the effect of E.Husserl's theory, consciousness,subjectivity,relationship between the subject and object and so on.I suppose to achieve an objective:being in the inner of ego, weakening and cancelling the might of intersubjectivity,and getting back to the"subject-object"mode,which is the original intercommunication and the basis of human being's harmony.
