Abstract: Rawls' original intention of “political turn” is to solve a problem inherent in the stability argument of A Theory of Justice.However,it seems to have brought more problems,including the possibility of overlapping consensus and the setting of political legitimacy standard.The existing interpretation of Rawls' political turn ignores the deepseated relationship between Rawls' political turn and the neoliberalism turn in Western society,and cannot provide an answer to the above problems.By drawing on Marx's ideological analysis of capitalist society,we can see that the overlapping consensus is possible because political values and life conceptions are shaped by the capitalist mode of production; The liberal principle of political legitimacy requires,and only requires,a social minimum in terms of economic distribution,which is the expression of the public political culture in western society after the neoliberalism turn in political theory.
