A general explanation is that postmodernism is a contradiction in terms, as post means after and modern means now, it is impossible for anything to be after now. The term itself is supposed to be deliberately unexplainablehttp://fordlcmusicvideo.blogspot.com/2011/01/postmodernism-another-definition.html. Modernism refers to a certain period of the western culture of artistic and sociological history. Postmodernism is a movement away from the viewpoint of modernism.Postmodernism rejects the modernist ideals of rationality, virility, artistic genius, and individualism, in favor of being anti-capitalist, contemptuous of traditional morality, and committed to radical egalitarianism.http://www.naciente.com/essay15.htm Many postmodern artists appropriate earlier modernist and classical works and combine or alter them to create a new, ironic piece.
Rene Magritte who was born in lessines, Hainaut (Belgium) in November 21,1898 a surrealist artist..http://www.magritte.com/2.cfm
Magritte’s work frequently displays a juxtaposition of ordinary objects in an unusual context, giving new meanings to familiar things. The representational use of objects as other than what they seem is typified in his painting, The Treachery of Images (La trahison des images), which shows a pipe that looks as though it is a model for a tobacco store advertisement. Magritte’s use of simple graphic and everyday imagery has been compared to that of the pop artists. His influence in the development of Pop art has been widely recognized.
In postmodernism my favourite style is pop art .Pop-art is images of popular things. Pop-art is images of ordinary objects, mass produced common everyday items that most people like and recognize. items like record labels, or logos, or packaging, and fashion pictures of people, Road signs, hamburgers, money, soda bottles, and machinery are also common subjects. http://www.the-artists.org/artistsbymovement/Pop-Art/
