Abstract ：What is a fair justice? Rawls proposes a contemporary social justice theory, which is known as the fair and justice theory; it not only merges the basic concepts of western justice, but also enlarges their connotations. This fair justice has been regarded in some works as a common concept of the term of a sound and lasting social cooperative system in a constitutional democratic society, therefore it is a justice included in the concept of a sound and lasting social cooperative system. This kind of justice is pragmatic while it strives for perfection at the same time. The author tries to deal with the problem of how to put this pragmatic-utopian theory into practice as well as maintain its long-time effect mainly in the Chinese background.
