If ever we were to reach a consensus, I think the Golden Rule would be the maxim of all maxim's.
I agree that it is a great Maxim, but it is not an Absolute. For example, it has two parts, and how you treat others depends on how you would like to be treated.
That's hardly an
example, IMO.
But yeah on the no absolutes.
WRT the golden rule: If you, yourself, did not want to be treated like you treat others, would you then NOT treat others as you would have them treat you?
Remember, relative morals can still be powerful and at a very high level.
But never absolute
