To confirm identity of the university, E. Spranger pointed out that we must escape from the unconsciousness of 1) the nature of the university, 2) problems caused from the dichotomy between job and non-job, and 3) problems caused from separation between research and education. Accordingly, our universities must review on: 1) the missions of scientific research, 2) appropriate educational method and 3) academic communities permitted and entrusted to universities. According to Spranger, the nature and essence of university is rooted in science or in scientific work that creates objective knowledge and the truth for human life. Thus in order to recover the essential image of university, it must perform the missions as follows. Firstly, they are liberated from unconsciousness of their position as the place creating objective knowledge and the truth. Secondly, they must not ignore the dialogical Socratic Method that means educational method in traditional colloquium of earlier universities. Third, they must (re)construct the academic communities in the university among educators, students and researchers and so on. The performance of their original missions will facilitate to construct the scientific world in the university. However, the university must give warning of corruption or manipulation of science continually. In other words, science in the university must not be victimized, what is worth, manipulated and operated from interior and exterior powers. Furthermore, if the university today has the prospect to manage \'science of totality\' - Wissenschaft der Totalitaet in Spragner\'s meaning - in order to approach to the total understanding of our life, it is an optimal approach to recover the identity of university.
