Abstract: Thomas Scanlon, who believes liberalism of equality, is a famous political philosopher. In the face of criticisms that Joho Rawls' A Theory of Justice got, based on Rawls' moral contractualim, he changed Rawls' research direction concentrating on macro-social institutions, came up with a substantial contractualism ,from micro angle to argue the nature of individual morality, and why we should concern right and wrong, and their priority over other concerns and values. This develops the contract form of Rawls' moral theory, and complemented Rawls' negative points. It has significant influence in contemporary ethics.

Key words: Thomas Scanlon, contractualism, reasonable rejection, reason
