The annoying thing is that some people use the word "post-modern" to look hip and educated. I am not saying you are like that but just saying that people just use the word to look sophisticated.
It is not clear what even that word even means or when that era started to part with that modernism era but I will guess its nature. The Post-Modern era started around the 50's, after World War II, when the T.V set was available in many homes which made mass media more pervasive. Values became increasingly more relative, mass media more prevalant, and the nation state breaks down. Values become more relative I say generally when there's lack of consensus on how one should live. Meaning there's is the weakening of any real religions and culture defining people's values along with the dissolution of community interaction. Again, mass media becomes prevalant with the television and internet and the danger is the fact that since it is so common that people become more uncritical and passive to it. The nation state dissolves in this post modern age because with the internet one can easily interact without physical limitations and things (information, labor, goods etc) can move around easily for work/ entertainment. Finally, the post modern age is marked by the blurring of any real and copy. Again, with the prevalance of mass media and anything being able to be reproduced and copied then it means it gets more difficult of telling what the original is. For example, images can easily be reproduced by anyone by using the photocopier or photoshop. Images can easily be crafted without referring to anything real. For example, one can take a photograph of something and put it on the net. One can easily manipulate that image and more one tampers with it then more it gets away from the original. But many images are presented as very photorealistic and real but one can not see the process on how it was created. Possibly it can be from a photo from a scene from reality or it could of been crafted completely digitally from photoshop. One can never really know.
The post modern age, I argue, is valueless because its values very relative and there's the weakening of true culture in Westernized countries, especially the Canada and the US. One can not have real culture when society has no direction or unifying values which ANUS argues it is because of democratization and multi-culturalism. They argue, there is such a thing as "race" and it shapes culture, which I agree. Culture is a product from a long period of history of that certain reace and ANUS points out multi-cultural societies have no true culture because they built societies recently. I say the problem is that the masses become more passive with the prevalance of generic multi national corporations and mass media. Who needs to make true culture when one can just watch TV and buy mall products. Generic, mass-produced products are preferred over true cultural products because they are cheaper, common and have more potential to generate money. I brought up mass media domination characterizes this age because it is very common and people rely on it for everything from work to entertainment to daily necessities. People spend their times living in digital-representational worlds on the internet and television than living.
