Jean Baudrillard - I must say that albeit he is a self-proclaimed postmodernist theorist, it is not at all fair to lump together with others (specifically those influenced from poststructuralism). Baudrillard is a materialist. In spite of that, he has other postmodern sensibilities (fragmentation, symbolic-surface function, etc.).
He talks about history and the linear construction of time, and how this has framed our thought processes. Because of this artificial linearizing of time, he pokes fun at "ends." For Baudrillard, time has, more or less, stopped. It is no longer a question of forward or backward.
He argues that we are speeding towards hyperreality, where everything is sterile and eternal. Using the example of the compact disc, he says (roughly) "If objects no longer grow old when you touch them, you must be dead." We need to see and experince death and decay to constitute life. My only concern is this implicit statement that there is a kind of default nature positon when things were right (vinyl records, no email, news travelling via mouth, etc.).
Overall, brilliant and stimulating.
