Michael Sandel is a contemporary political philosopher. He is the Anne T. and Robert M. Bass Professor of Government at Harvard University. Sandel subscribes to the theory of communitarianism, and in this vein he is perhaps best known for his critique of John Rawls's A Theory of Justice. Rawls' argument depends on the assumption of the veil of ignorance, which allows us to become "unencumbered selves."
Sandel's view is that we are by nature encumbered to an extent that makes it impossible even in the hypothetical to have such a veil. Some examples of such ties are the ties we make with our families, which we do not make by conscious choice but are born with them already attached. Because they are not consciously applied, these ties are impossible to separate from someone. Sandel believes that only a less-restrictive, looser version of the veil of ignorance can be possible. Rawls's argument, however, depends on the fact that the veil is restrictive enough that we make decisions without knowing who will be affected by these decisions, which of course is impossible if we are already attached to people in the world.
He teaches the famous 'Justice' course at Harvard, conducted at Sanders Theatre, in which most undergraduates encounter moral philosophy and reasoning for the first time.
Sandel argues that modern day liberals like big judiciary and big government, whilst modern day conservatives disdain those two and promote big corporations. Sandel is against all of these, and hopes to create a feeling of community among Americans.
