The scientific method, if applied socially, will work.
It does not attain perfection. It's just a far better system
than any other system that we know of today.
I'm not talking about utopian societies
where everybody is happy. There's no such condition.
All social systems are in a state of evolution.
An established society is one that has found a way
that worked for the people in control of that society.
All societies are emergent, constantly evolving.
There's no such thing as attaining a sane world.
Sanity depends on the acquisition of information
and applying that information to the well-being of all people
and protecting the environment.
That's what I mean when I use the word sanity.
