Abstract: Marx's struggling for liberation of all mankind's life is closely related to his pursuit of social order that is fair and reasonable for mankind. Marx's early justice thought laid a foundation for the formation and development of his justice thought. "Justice is not thing-in-itself" is the logical starting point of his justice thought; "Fair, free censorship of books and newspapers is needed more necessarily”, is the sign of his political path on fighting for justice; "Inequality of man's world is the refraction of equal color " is the beginning of his defending labor people's material benefits and his fighting for justice.

Key words: Marx；justice thought, equality, material benefits
