I really like:
The concept popularized by John Rawls that when organizing a soceity, a useful thought experiment goes like this:
“No one knows his place in society, his class position or social status; nor does he know his fortune in the distribution of natural assets and abilities, his intelligence and strength, and the like.”
But pretend that you don’t know what starting point you will get. So make a society that you would be willing to enter from any starting position.
The line from Talking Union that goes “Take it easy, but take it”
