I've recently been reminded of an interview that was, sad to say, in one of my art history books. One of the crazy things said in it was that the London fog didn't exist until someone decided to paint it. Cue facepalm.
Now, I'm not sure he meant it literally, but he did seem to think that no one really experienced it until it was painted, as if no one took a moment to admire the landscape on a foggy day before then. I find it alarmingly common among PoMos to think that some form of human experience or expression is sacrosanct. I also find it enormously silly when some of these sorts lash out against a new medium, like digital art. Hell, there were some who complained about store bought paints because "real" artists made their own. New media may require different approaches, but there's nothing inherently wrong or shallower about them. It's perfectly possible for some artsy type to make a video game that's on par with the classics.
Of course, I have to drift this subject into how science is done. Science strives to remove the subjectivity of the human element. A thermometer makes a certain reading, and unless you buy into PoMo epistemology, that reading will be the same for anyone. Put simply, it doesn't matter who uses the thermometer, it only matters how they use it and how they handle the data. Done with enough double checking against experimenters accidentally or intentionally biasing the instrument, you will get a more accurate result with thermometers than you will without them.
Being able to quantify such things rubs many PoMos the wrong way. A lake measured at a certain temperature may feel very different depending on who's getting in when. On a hot day, the relatively cool water may feel refreshing. For someone experiencing hypothermia after being locked in a fridge, the water may feel warm. Either way, it's X degrees, and the human aspect changes the subjective experience. Knowing what the temperature is will tell us how different people may experience it, as well as things like what chemists can do with it. Sometimes I wonder if PoMos try to pad their schedule by making sure there's always more to gibber about.
