Postmodernism developed during the 60s: itis a culutural trend of thought that does no longer believe in the concept of truth, the concept of center and it puts also the concept of authority into doubt.

In modernism there was the need to look for a point of reference and this posed a question  about art, too and its role as well. Research on art therefore become the most interesting concern for artists. 

Postmodernism questions all that was traditionally accepted even the need to lok for a meaning, a centre and thje distinction between higher and lower generes. It  concludes that there is not a single center or an absolute truth. There are many  centers and the meaning is always differed because meaning is never stable. Therefore the concept is strictly related to the relationship between signifier and signified.

In Postmodernism the position of the reader is the privileged one because he/she gives different meanings to what he/she is reading. 

One of the best examples of Postmodernism are provided by the novel Oranges are not the Only Fruit" (J. Winterson) and "Nice work" (David Lodge). The first one relies on restructuring  the books of the Bible projecting them into a new context and the second one underlines the postmodern and feminist position of Robyn, the female protagonist of the story whereas she does not believe in the concept of character according to the traditional novel which she considers a simple product of the capitalist myth of the self made man. She does therefore no longer believe in the concept of a single, unique self becuse people produce their selves in language.
