As “I” and “We”, we exist “now and here”. However, we should always doubt that the first person singular and plural is not a just fleeting phenomenon, appeared in the interface of the two real concept-existents such as “I as We” and “We as I”. Hegel, in his Phenomenology of Spirit, also presents our existence as “Spirit” in the circular relationship “I that is We and We that is I”. Therefore, to clarify this internal relationship, we have to first ask , about the distinctions between two moments of knowing such as “for conscience (für es)” and “for us (für uns)”, and then, about the sense of “Circle”. These questions lead us to eliminate the essential distinctions between these moments, and to build up the conscience in his self-developing process called “I”. As a result, we could reconfirm the relationship between “I” and “We” in the Circulation-relationship, where one goes always over the other for their mutual Self-formation.
