These exclusions and inclusions stand in antagonistic relationship to other discourses, other possible meanings, other claims, rights, and positions. Knowledge does not reflect power relations but is immanent in them. In a postmodern world view, there can be no universal truth or universal reason. In its most conservative sense, postmodernism only tries to understand multiple forms of difference, multiple interpretations, multiple ways of knowing or constructing knowledge. This could be called the phenomenology or hermeneutics of knowledge.
Postmodernism strives to deconstruct or unravel social, cultural, and human differences.
The locus of power shifts to the underprivileged, the marginalized, and the oppressed. Critical postmodernism is about real people struggling in the everyday world within their multishaped identities and subjectivities. What the relations of race, class and gender may be to any individual will always be different and changing. Foucault believed that a true critique of society, of reality, of truth, could never be absolute, but was constantly in flux as changes occurred through the progress of history. He disagreed with the Enlightenment's belief in the ability to locate any permanent foundation of reality or absolute truth.
