[James C. Bennett]

Since survival is good accomplished by the Golden Rule, is it true that cultures/societies which last the longest are therefore the best (most good)?

When a society that violates the Golden Rule comes with an expiry date, how is it survival? More importantly, how is such a society one that is thriving? (Note the key difference in terminology). "Longest lasting" is no criteria - influence, gravitas and sustained success are more important. Under these classifications, slave states fail miserably.

When a society that violates the Golden Rule comes with an expiry date, how is it survival?

It is survival if it survives.

"Longest lasting" is no criteria

If it lasts long it survives long, by definition.

influence, gravitas and sustained success are more important

So if it has all that for five years that's long survival in your criteria? Would this society outscore one who lasted for a thousand years through times of influence and gravitas, etc. and times without it?

Certainly not.
