 Rawls makes four arguments in Theory, Part I for the principles of justice. The main argument for the difference principle is made later in section 49, and is substantially amended and clarified in Justice as Fairness: A Restatement. The common theme throughout the original position arguments is that it is more rational for the parties to choose the principles of justice over any other alternative. Rawls devotes most of his attention to the comparison of justice as fairness with classical and average utilitarianism, with briefer discussions of perfectionism (TJ, sect. 50) and intuitionism. Here I’ll focus discussion on Rawls’s comparison between justice as fairness and utilitarianism.
