I was never sure how to deal with this postmodernist crap. When someone deliberately confuses the map and the territory, what can I say?

Let us just observe that sometimes, I believe something, and then, I see something else happen. That tend to give me a sense that something is going on outside of my mind. http://yudkowsky.net/rational/the-simple-truth

This generalizes to the entire humanity, by the way. Most people believed in a Young Earth, then we discovered fossils. Most people used to think the Earth was the centre of the universe, then Copernicus, Kepler, and Newton, proved otherwise.
