“Postmodern” is a stupid word on the face of it. It was created when an attempt was made to designate one recent historical period (now over) as “modern”, making it a contradiction in terms. If you accept the basic illogic, then “postmodern” would mean “what comes after that”. “Modern” means “now”, “that which is temporary/passing/the current fashion”. It is directly related to the Latin root for passing fashions, which is why it is silly to be proud of being modern.
