This is an especially hard concept for college students just realizing their identity as adults.
Postmodernism troubles identity.
It lead us to realize that identity is complicated, indeed contradictory. I chose this college. In this sentence I is the subject, who has the power to choose. People within the subject's field of vision or experience are, therefore, objects, since they exist for us. Postmodernism troubles I-dentity because it recognizes that I, the subject, is also the object of someone else's interest or gaze.
