No standards or markers to which people can identify their 'self'. You can be anything you want to be. Good idioms when used in moderation. There are things that we can't do, individuals should not build expectations of themselves to which they could never fulfil. Sometimes other people or societies do and should tell us what to do.
Post modernism seems to have broken from the society as collective responsibility and control.
Now the primary unit is the individual. Not only is the individual primary but this moment, now, is primary. I am a person of the world. It is the uniqueness of individuals that is so appealing about ' people'. So rather than negating the specific, it should be celebrated.
