Overview: Aristotle believes the purpose of politics is to promote and cultivate the virtue of its citizens. The telos or goal of the state and political community is the good life. And those citizens who contribute most to the purpose of the community are the ones who should be most rewarded. But how do we know the purpose of a community or a practice? Aristotles theory of justice leads to a contemporary debate about golf. Sandel describes the case of Casey Martin, a disabled golfer, who sued the PGA after it declined his request to use a golf cart on the PGA Tour. The case leads to a debate about the purpose of golf and whether a players ability to walk the course is essential to the game.
