What happens when you take postmodernism a bit too far. The basic tenet of postmodernism is that we need to be aware that everything we do is subjective, no matter how much we strive for objectivity. We are always making assumptions, and we need to examine these assumptions and their origins in order to more fully understand whatever it is we're thinking about. If you take it too far, you end up with something like, "if everything is colored by our assumptions and we have no way of being truly objective, then how can we ever find the truth? What's the point of studying anything if we can never really know anything for sure about it?" This is a pretty useless attitude. A dash of postmodernism here and there is good, because it forces us to look at where we're coming from. Too much, and that's all you'll taste. Kind of like pepper.
