Hi,
Hope this helps:
Marry Shelly's Frankenstein can be considered a postmodernist text because it takes into account of contemporary issues faced in the 'everyday society'. To be able to interpret Frankensein as a contemporary text, you need to adapt a perception; for example: an existentialist view (there are fragments of existentialism in todays society - Deconstruction method).
Existentialism is a prominant issue explored through Shelly's exploration of the theme prejudice. Shelly has employed symbolism to articulate the meaning given to the monster. The monster is symbolic of humanities existentialist drive, or self actualising tendency it faces in the pursuit of science and knowledge. The insatiable desire to 'seek knowledge' will ultimately lead to the destruction of ones self. If we have a look at the 'monster', he is essentially an eloquent by-product of science. Its original intention was for the 'greater good of humanity' (add evidence) but in consequence it ends up destroying everything which leads the issue of the human condition...etc
