An uncouth and a liberal enter in a bar.
The uncouth asks:
- "Why  limit  myself in  pursuit  of my own advantage?"
The liberal answers:
-  "You  have what you have only because others  constrain themselves,  in ways  that  make  for  a  fair  cooperative  venture  for  mutual  advantage. Constrain  yourself  by  those  rules  in return,  and  you give them fair return  for  what they give  you."
- But my natural right to property....
- Did you hear "you have what you have only because others agree to constrain themselves"?
