  5. Two causes can be identified for this : the first cause is external, by which more and more appropriations of post - structuralism and post - modernism from the west have led cultural criticism to the pursuit of an impromptu pleasure, thus making cultural criticism into an intelligent game which is of great fun but not very practical ; the second cause is internal, by which intellectuals have changed their roles from " legislators " to " interpreters " since 1990 ' s, who, on one hand, could not take the responsibility of criticism, and on the other, changed the nature of cultural criticism by bringing a set of ideologies and ideas into it
