Political philosopher who teaches at Harvard. Rawls is probably the most widely-read philosopher of the twentieth century. His books, Political Liberalism and A Theory of Justice, revived American political philosophy.

Rawls bases his theory on a social contract. He opposes the utilitarian position of justice because he believes that justice is the outcome of more than pure utility. Rawls defines justice as fairness, and proposes a means to true fairness: the "veil of ignorance". Basically, the idea is that if everyone were behind a veil of ignorance, not knowing their position in society, they would administer justice fairly, giving everyone in all social positions their due. Thus, the rich would be more sympathetic to the poor, and those with the advantage of an education would be more helpful to those without. This is also known as distributive justice.
