Einstein whould cringe at "God plays dice." What's _not_ relative?
Even the speed of light can change. A large amount of relativity
existed before Einstein. Einstein got rid of what was left, except
the speed of light. Quantum Mechanics shows that even the speed of
light is not absolute.

Perhaps I wasn't clear, but you just made my point.

Again, what's _not_ subject to relativity? I realize that TOR
breaks down at the Quantum level, but in my day-to-day life
this doesn't effect me alot. And please don't call me "New Age".

I'm not saying TOR solves ethical problems. I will say that TOR
provides a mental framework which can be used effectively in ethics.

I don't think you're being confrontational. I think I'm being
misunderstood. I'm saying "If something exists it is subject to
relativity". I'm also saying that TOR provides a nice framework
for dealing with some sticky issues.
