It is far from a self-evident truth that education should be just. The combination of education and justice requires a critical examination. Education means the understanding of the actors. The first understanding of the actors is their infinite richness. Review of the richness is based on the revaluation of educational justice:highlighting the original meaning of education. In the original meaning of education, the two factors of the existing world and the people should be first highlighted as the actors. Authentic education is manifested by the interaction between the people and the world, i.e, appreciating the good, which is the manifestation of human being. That is to say, education means human justice. Achieving educational justice demands world justice, understanding justice and practicing justice.
