Best piece of philosophical advice I ever got from a former professor I had:
If you ever meet a person who claims morality is relative and therefore no one should judge…steal his stereo.
Weeelll, maybe I’m exaggerating on the “best advice” part, but it brings the point home, doesn’t it?
I was having a discussion on moral relativism with my senior class today, and I did just that (except, I didn’t steal a stereo; I stole an IPOD). When the student objected, I said, “meh. If that’s your morality, fine, don’t steal IPODs yourself. But don’t push that belief on me.” They got a good chuckle out of that. It usually brings the point home pretty well.
