The problem with the sun thing was the discussion after it. He (professor) said it use to be truth that the sun went around the earth. I said that was a false belief and that it didn't change the nature of actual truth. The discussion went on and basically ended with "we can't really know nothing." I can stand moral relativism, but not reality relativism, because almost no one actually believes it. It's just a final point someone raises whenever they've been put down in an argument.
I read a book - a light novel really, where a lecturer said something like this, I think about the rules of physics. The seven year old who happened to be in the audience wondered if he felt that way when he was on the plane that brought him to the lecture.
You are right - almost no one really believes that. He's either a real radical - which would be lucky for you because one doesn't often get to meet/observe someone who lives as though reality is arbitrary and changeable - or he is an idiot which is too bad because the class title sounds very interesting.
