That’ll never happen, anymore than we’ll ever agree on what constitutes “liberty,” “democracy,” “capitalism,” etc. Okay, maybe it’s more likely than for those, but still fat chance.
To my mind we were special, long ago. That ended either in 1861, 1913, or 1932. Not sure which.
If we can’t agree on defining it, then what are we fighting for? Some undefined Utopia like the Communists?
