Good overview of John Rawls’ methods and philosophy.  “Many of us feel that our societies are a little – or even plain totally – ‘unfair’. But we have a hard time explaining our sense of injustice to the powers that be in a way that sounds rational and without personal pique or bitterness. That’s why we need John Rawls (1921-2002), a twentieth-century American philosopher who provides us with a failproof model for identifying what truly might be unfair – and how we might gather support for fixing things.”
