It is man who wrongly put himself at the center of the world. It is man who naively believes that he is the master of this world. The constructed modern self is oppressive and violent. Therefore, a postmodern man should deconstruct the modern self. Postmodernism dismantles the humanism of modernity.
Modernists are activist, optimistic, and self-confident.
Postmodernists are passive, cynical, and insecure. A postmodernist welcomes the idea of a decentered self because in this way one can be whoever one wants to be. There is no need to take on a fixed self. The keyword here is pluralism. Everyone should be in a process of constructing and deconstructing one's self.
