Professor Sandel presents Kants objections to Aristotles theory. Kant believes politics must respect individual freedom. People must always respect other peoples freedom to make their own choices—a universal duty to humanity—but for Kant, there is no other source of moral obligation. The discussion of Kants view leads to an introduction to the communitarian philosophy. Communitarians argue that, in addition to voluntary and universal duties, we also have obligations of membership, solidarity, and loyalty. These obligations are not necessarily based on consent. We inherit our past, and our identities, from our family, city, or country. But what happens if our obligations to our family or community come into conflict with our universal obligations to humanity?
